Because more poultry meat and eggs are being produced worldwide, people are asking for better, more sustainable ways to farm. This means finding new and better ways to feed animals in the future. From 2000 to 2020, global egg production went up by more than 41%, increasing from 51 million to 87 million tonnes, with an average annual growth rate of 3%.In 2023, poultry meat production hit 145 million tonnes and is still rising. With 6.29 million tonnes produced in 2020, India is fast approaching the level of production in the USA (6.29 million tonnes) produced in 2020. With an average egg size slightly lower than that in the USA (average weight of a standard large chicken egg 56.7 grams (2 oz) in the USA as against 50 to 55 grams in India), the Indian egg sector estimated that they have already overtaken the USA in terms of the number of eggs produced. India produced 149.11 billion eggs in the 2024–25 period, while the United States produced approximately 105 billion eggs in 2025. This growth is making it more important to find sustainable ways to feed animals.Even though raising poultry is less harmful to the environment compared to other types of animal farming, it still has some negative effects, such as increasing global warming, making water too rich in nutrients (eutrophication), and making soil too acidic. Low-carbon poultry feed is now moving from just an idea to real, practical use. Feed is responsible for about 70% of the total carbon footprint in poultry farming, so it’s the biggest area where we can cut down on carbon emissions. To make poultry farming more sustainable, we need to change how we get, mix, and use feed. Soybean meal and fishmeal have been the main sources of protein for animals, used in everything from chicken farming to fish farming. But keeping on using them at the same levels is bad for the environment. The reason we’re looking for alternatives isn’t because these materials don’t work well for animals—they are very effective. It’s because they cause serious environmental and economic problems, especially for systems that try to be sustainable and manage fish resources properly.

CIRCULAR AND ALTERNATIVE INGREDIENTS
Producers are actively moving away from relying entirely on conventional corn and deforestation-linked soy. Feed formulations are increasingly incorporating agro-industrial by-products, former foodstuffs (circular feed), and alternative protein crops like rapeseed and peas.
Life Cycle Assessments show that feeds formulated with these by-products can have a carbon footprint nearly 40% lower than traditional raw material feeds.

THE “BIG THREE INGREDIENTS” OF POULTRY FEED
Poultry sector consumes ~60% of India’s maize (~20+ million tonnes annually).Soybean meal demand: ~6-7 million tonnes domestically. In commercial broiler and layer operations, dry fish meal is rarely used When added at strategic levels, typically 3-8% in starter feeds and 2-5% in grower phases, fish meal enhances palatability, encouraging birds to consume more feed during critical early stages. This increased intake, paired with high digestibility, results in superior weight gains and improved FCR. In the layer segment, specialized demand exists for producing enriched eggs. The long-chain n-3 fatty acids (like DHA) in marine lipids transfer efficiently into the yolk.

1. SOYBEAN MEAL (THE PROTEIN BASE) : Soybean meal is the main source of protein in chicken feed around the world, but it has a big impact on the environment. The protein in soybean meal is high in lysine, which is first limiting amino acid in most chicken diets. This makes it a great match for grains like corn and wheat. India does not allow growing or bringing in raw genetically modified (GM)soybeans or seeds. India’s soybean production fell a lot during the 2025-2026 growing season, reaching about 11 to 12.7 million tons, which is much lower than before, causing a serious shortage of supply. When there are not enough non-GM soybeans locally, they get them from certain African countries. Non-GM soybeans are more expensive than GM ones. Even though GM soybean meal has been allowed sometimes to meet the protein needs for animal feed, there are worries about the effects on the environment. These worries include carbon emissions from cutting down forests in important areas like the Amazon and Cerrado, more risks for climate change, loss of wildlife, and pollution from farm chemicals running into water.

2.CORN / MAIZE (THE ENERGY SOURCE) : Corn provides the bulk energy in most poultry diets. While corn generally has a lower carbon footprint per kilogram than soy, birds eat much more of it. The primary carbon issue with corn is its heavy reliance on synthetic nitrogen fertilizers. Manufacturing these fertilizers is extremely energy-intensive, and applying them to fields releases nitrous oxide (N₂O),a green house gas nearly 300 times more potent than carbon dioxide. Tractor fuel for plowing is another important issue.

3.FISH MEAL (THE SPECIALITY PROTEIN) : Though used in far smaller amounts (typically for young chicks or breeder birds), fish meal has a complex environmental footprint. The issue of TMA accumulation leading to a fishy flavor in brown-shelled eggs arises from a genetic defect in up to 10% of brown-feathered hens. Normally, TMA is oxidized in the liver into a harmless compound by the action of the enzyme trimethylamine oxidase. The synthesis of this enzyme depends on the expression of the FM03 gene, located on chromosome 8. In the case of anon-synonymous mutation in the FM03 gene (designated T3295),hens cannot oxidize TMA, which then accumulates in the yolk. Poultry diets restrict fish meal to 5-10% of total feed due to ecological inefficiencies. Fishmeal is sourced from small forage fish like anchovies and sardines, which are crucial to the marine food web. Overfishing these species endangers higher trophic levels, leading to decline predatory fish, marine mammals, and seabirds.Moreover, forage fish populations are vulnerable to climate change, causing unstable fishmeal supplies and significant price volatility.India is the third-largest producer and exporter of fishmeal.

ECONOMIC HURDLES TO TRANSITION OF CIRCULAR PROTEINS
The transition to circular proteins, such as microbial biomass, insect meal, or fermented agro-industrial waste, is essential for stabilizing ecosystems and is crucial for a sustainable livestock industry. However, commercial feed mills face significant economic barriers due to scale, commodity pricing, and supply chain maturity, making it challenging to replace traditional soybean meal. Here are the primary economic hurdles commercial mills face today:

THE PRICE PARITY GAP
Decades of agricultural subsidies, optimized supply chains, and massive economies of scale keep their prices relatively low and stable (historically ranging from $600-$750 per ton for soy, and $1,500 to $2,000 for fishmeal). In contrast, alternative proteins like Black Soldier Fly Larvae (BSFL) or microalgae carry immense initial capital expenditures (CapEx) to build high-tech bio-manufacturing or fermentation facilities.
Although insects like Black Soldier Fly Larvae (BSFL) raised on organic waste represent the ultimate circular protein, converting low-value biomass into high-value feed with a minimal land and water footprint. BSFL defatted protein meal and de-oiled powder generally trade between ₹110 and ₹250 per kg in Indian market & wholesale price roughly between $1,320 and $3,000 USD per ton.

SCALE AND VOLUME CONSISTENCY
Commercial feed mills produce feed continuously, requiring tens of thousands of tons of standardized ingredients every single month. Currently, very few alternative protein manufacturers can guarantee that volume without interruption. If a mill alters its highly specific formulation to include 5% insect meal, and the supplier falls short on delivery, the mill has to halt production, re-calibrate its software, and reformulate the diet using different ingredients. This downtime is extraordinarily expensive.

HIDDEN COSTS OF NUTRITIONAL REBALANCING
Soybean meal and fishmeal are highly dependable. Nutritionists have a clear understanding of how these ingredients function within the digestive systems of fish and birds. When a mill uses insect meal or a plant-based alternative to fishmeal, the amino acid profile changes. As a result, the mill needs to purchase additional synthetic amino acids, such as L-methionine or L-lysine, along with specific feed enzymes to compensate for the missing nutrients. This helps maintain the animals’ growth rates. Even if the base alternative protein is priced competitively, these added ingredients increase the overall cost of the final feed formulation.

RETROFITTING MILL INFRASTRUCTURE
Feed mills are designed to handle, grind, and pellet traditional grains and meals. However, alternative ingredients often have very different physical properties. For instance, some insect meals contain significantly more fat than solvent-extracted soybean meal. High levels of lipids can cause blockages in extruders, reduce the quality of feed pellets (making them prone to breaking during transport), and damage machinery. To effectively use these new ingredients at high levels, mills usually need to invest heavily in upgrading their equipment, such as adding new vacuum liquid-coating systems for fats. Many mills are reluctant to make these costly investments due to financial concerns.

REGULATORY APPROVAL COSTS
The global feed industry has strict rules to stop harmful substances from getting into the food chain. To get approval for a new type of protein, like microbial biomass or insect protein, used in animal feed, companies must do many expensive and time-consuming tests. These tests check for safety, look for heavy metals, and measure how well the protein is digested. This process can take many years.The cost of these tests ends up being passed on to the feed producers, which raises the cost of the ingredients. Unless these alternative proteins can be made in large amounts and sold at prices that are as good as soy or wild-caught fish, they are probably only used in special, high-end, or environmentally friendly feed products, not in regular, mass-produced feeds..Fig.2:

It shows how being efficient with resources, taking care of the chickens’ health and happiness, keeping the farm safe from disease, making sure the chickens are productive, and making the whole food system strong and able to handle challenges are all connected and important.

THE GLOBAL RACE TO DECARBONIZE LIVESTOCK DIET

CIRCULAR INGREDIENTS & CARBON REDUCTION
Upcycling Waste: Using agricultural and slaughterhouse by-products (like DDGS, fruit pomace, and rendered fats) reduces reliance on land-intensive virgin crops and prevents landfill methane. The sustainable use of fruit and vegetable residues (FVRs) in poultry feed formulations has gained considerable attention due to their potential in advancing animal health However, certain challenge such as anti-nutritional factors, palatability issues, and processing techniques are also associated while incorporating these residues into poultry diets. Fermentation technologies create new opportunities to recover nutrients from agricultural residues and improve their value in poultry diets.

Carbon-Optimized Formulation: Modern feed software integrates Life Cycle Assessment (LCA) data to dynamically select ingredients based on their carbon footprint, not just cost and nutrition. LCA is a measurement of the emissions generated during its cultivation, processing, and transport. The software can calculate the exact environmental cost of using raw protein crops (like soy) versus supplementing with synthetic amino acids. It optimizes the diet to prevent protein overfeeding, which simultaneously lowers the feed’s initial GWP (Global Warming Potential) and reduces the nitrogen output (and offensive odors) in the poultry droppings.

THE SHIFT TO DDGS (DISTILLERS DRIED GRAINS WITH SOLUBLES)

Cost Advantage: Maize-based DDGS (₹17-₹20/kg) is significantly cheaper than soymeal (~₹40/kg), driving rapid adoption in the poultry industry.
Substitution Limits: DDGS can replace 25-30% of maize demand. Insect protein and algae can replace small portions of soy (5-10%).
Ongoing Conventional Reliance: Despite these alternatives, conventional ingredients will still make up 60-70% of overall feed requirements.
PRECISION NUTRITION
Targeted Diets: Formulating feed to match exact amino acid and energy needs improves the Feed Conversion Ratio (FCR).
Lower Emissions: Preventing protein overfeeding reduces nitrogen in manure, which directly lowers harmful nitrous oxide (N₂O) emissions downstream. Fig.3

Fig.3: Alternative protein sources for animal feed in a circular bioeconomy could include things like leftover materials from farming and food processing, meals made from insects and worms, leftovers from biorefineries, proteins made by microbes, and by-products from aquatic sources.

BETWEEN REALITY AND RHETORIC: LOW-CARBON POULTRY FEED
Moving from using a wide variety of ingredients in poultry feed to providing exactly what the birds need at each stage of growth is key to creating real low-carbon feed. While some talk about replacing soy with new ingredients, the actual science is about making tiny, precise changes. It’s about giving birds exactly the right nutrients they need, in the right amounts, so nothing is wasted. Real reductions in carbon emissions from poultry feed don’t come from using popular or fashionable ingredients. They come from making sure every part of the feed works as efficiently as possible. Ensuring every gram of feed is used well is the best way a farm can help the environment. Instead of providing too much crude protein, experts can use specific synthetic amino acids like L-Methionine, L-Lysine, and L-Threonine.This helps reduce the total amount of crude protein in the birds’ diets. By cutting crude protein by just 1.5%, farms can lower their carbon footprint by about 70 kg of CO₂ equivalent per ton.

CONCLUSION
Despite having significant potential, incorporating insects, algae, fermented products, and agricultural and industrial by-products into chicken feed continues to face multiple challenges. These challenges include scientific, technical, economic, and legal difficulties. For insects, key issues include variability in their nutritional content based on their diet, high chitin content that complicates protein digestion for chickens, higher production costs compared to traditional protein sources, and the absence of established international safety and quality standards. Consumer acceptance of chicken products derived from insect-based diets remains uncertain, which may hinder large-scale adoption. The effort to reduce the carbon footprint in chicken feed presents a mix of real benefits and exaggerated claims. While some measurable progress is achievable, the extent and impact of these improvements often fall short of what companies assert. Reducing the carbon footprint in chicken feed is neither a complete solution nor a total myth; it represents incremental steps within a broader system that is not sustainable. The true advantages come from the following areas:

– Integrating a circular bioeconomy into feed production
– Minimizing reliance on imported protein
– Utilizing waste materials effectively
– Developing better alternative ingredients

The industry must shift from making grand promises to achieving tangible improvements. This involves recognizing and celebrating small achievements, such as 5-10% reductions, while also being honest about limitations and working towards broader changes that extend beyond mere feed modifications. This conclusion reflects both the actual progress being made and the gap between marketing claims and real-world outcomes, offering a balanced assessment of the industry’s current position regarding sustainable feed promises. Hybrid feeding systems that combine commercial and alternative feed sources generally provide the most consistent results, although maintaining mineral balance is essential during the laying phase.

Importance of Livestock and Poultry Sector in India

India’s livestock sector plays a crucial role in the country’s agricultural and economic landscape, supporting the livelihoods of millions by providing employment, income and nutritional security. Poultry and livestock sector provides essential inputs for sustainable farming practices, ensuring the country’s food security. India’s poultry industry is currently valued at $ 30 billion which engages over six million people (both directly as well indirectly) and the poultry industry has grown rapidly over the past decade. Indian poultry industry is now one of the most efficient producers of broiler meat and eggs globally, due to well established integrated companies, contract farming and a strong domestic market.

Rising Growth and Feed Demand Imbalance
The livestock sector – dairy, poultry, fisheries and allied sector is witnessing a much faster growth than the agriculture crops (Soybeans & Maize), there is apprehension that domestic feed production may not be able to ensure steady supplies while exposing the sector to price volatility. The Confederation of Indian Industry (CII) in its vision document 2047 for the Indian poultry sector has also mentioned that the sector is growing at a healthy rate of 8% annually and could see further acceleration. Availability of good quality feed ingredients and their prices are major challenges for manufacturing of good quality compound feeds.

Role of India–US Interim Trade Agreement
Under the recently announced India-US interim-trade, the decision to eliminate or cut duties on a range of items from the US including dried distillers’ grains (DDGs) and red sorghum, is likely to ensure steady supplies of animal feed in coming years. Commerce minister Piyush Goyal had stated that India will provide quota-based duty concessions on DDGs to the US under the deal. Feed demand is projected to grow faster than domestic supply, making large scale imports necessary by the early 2030s. Domestic production of energy sources like maize and protein sources like soymeal often fall short of growing demand of the poultry, dairy and fisheries sector.

Feed Cost Pressure and Need for Imports
Domestic feed supply is increasingly constrained by limited arable land and productivity gaps. The feed costs constitute 60% to 65% of the cost of the production of the animal husbandry sector any volatility in the feed prices lead to rise in cost of production and subsequent rise in prices. Thus, feed imports, especially of reduced or zero duty imports of soybeans / soybean meal and maize, can help bridge the demand-supply gap. Imports from established origins such as US soy can provide consistent, high-quality protein during periods of domestic tightness. When used judiciously, imported soy can help smooth feed costs, improve formulation consistency, and enable feed manufacturers to meet the quality benchmarks demanded by large integrators and processors.

Growing Demand for Protein and Feed
With increase in income and urbanisation as demand for dairy and poultry products increases, according the United States Department of Agriculture (USDA) in its report titled ‘The Growing Demand for Animal Products and Feed in India’ has stated that at the current growth in the productivity of maize and soybean, would not be able to meet rising demand of feed. Feed demand is projected to grow faster than domestic supply, making large scale imports necessary by the early 2030s. “By ensuring a timely and cost-effective supply of these essential feed ingredients, the government is directly addressing the challenge of feed inflation. This will not only stabilise production costs for farmers but also ensure that high-quality protein remains affordable,”

Industry Concerns Over Feed Availability
Several National and State level Poultry Associations in a recent communication to Shri Rajiv Ranjan Singh, Union Minister of Animal Husbandry, Dairying and Fisheries, Government of India, has raised concern about availability and rising price of soybean meal in the country which pose risk to poultry production. The sector fears a crisis, which can severely affect livestock production and consumer prices. With nearly seven months until the next harvest of domestic soybean products, sustaining poultry production at viable cost will be difficult, directly impacting egg and chicken prices and overall inflation. Even maize prices have witnessed volatility as demand for the grain is rising not only because of rise in animal feed demand but also its being used for making ethanol and other industrial use.

Future Demand Projections (2047 Vision)
India’s population is around 1.4 billion and is projected to be approximately 1.53 billion by 2047. This increase in population directly correlates with the higher demand for food including eggs and chicken. Per capita poultry meat and eggs are expected to be 15 kg and 200 eggs annually by 2047. Around 38 million tonne (MT) of broiler feed and 34 MT of layer feed will be required in 2047. At 30% penetration rate, cattle feed requirement will be around 90 MT in 2047. Fish and shrimp feed required will be around 7 MT in 2047.

Way Forward: Ensuring Sustainable Feed Supply
Ensuring sustainable feed supplies in coming years would be a key challenge for the sector. By ensuring cost-effective supply of animal feed ingredients, the government can directly address the challenge of feed inflation. This will not only stabilize production costs for poultry, dairy and aqua farmers but shall also ensure that high-quality protein remains affordable for the consumers. The interim deal with the US provides a window of opportunity for allowing feed ingredients imports which is expected to boost the sustainable growth of the India’s poultry sector in the coming years.

Patna, April 23, 2025 — The Compound Livestock Feed Manufacturers Association (CLFMA) of India, in Collaboration with the U.S. Grains Council and with support from the Bihar Poultry Farmers Association (BPFA) successfully hosted a seminar at Patna. The seminar, themed “Poultry in India: Current Challenges & the Way Forward,” brought together more than 60 participants, including feed manufacturers, poultry farmers, nutritionists, grain suppliers, and researchers from across the region.

The seminar opened with a welcome address by Ms. Nayantara A Pande, Marketing Specialist, U.S. Grains Council, followed by a keynote on “Poultry in India and The Potential” by Mr. Divya Kumar Gulati, Chairman, CLFMA of India. He highlighted the urgent need for collective action to address rising feed costs and market volatility, stressing that strategic collaborations will be pivotal in driving sectoral resilience.

Mr. Divya Kumar Gulati, Chairman, CLFMA of India, shared, “The Indian poultry industry is at a critical crossroads, where timely interventions and strategic collaborations are essential to overcoming the challenges posed by rising feed costs, supply chain disruptions, and market volatility. According to a recent Crisil Ratings report, the industry’s profitability is expected to dip by 50 basis points in the 2025-26 fiscal year, largely due to the rising prices of key feed ingredients like maize and soybean, which account for 90% of total feed costs. However, revenue growth is still projected to rise by 8-10%, driven by strong demand and consumption. Events like these provide an invaluable platform for exchanging insights, fostering collaboration, and exploring sustainable solutions that will not only benefit our sector but also contribute to the nation’s economic resilience.” The seminar was anchored by engaging sessions led by leading voices from the Indian poultry and feed sectors.
