How many gallons of water does it take to make a pound of chicken?

Raising chickens for meat consumption requires a tremendous amount of water. From growing chicken feed to processing the birds, water is essential throughout the various stages of chicken production. With water scarcity becoming an increasingly pressing issue globally, determining the water footprint of chicken is important for understanding the environmental impacts of our food choices.

So how much water does it really take to produce a pound of chicken meat? Let’s take a detailed look at the water usage in the chicken supply chain and the factors that influence the water footprint of chicken.

Quick Answers

– It takes approximately 468 gallons of water to produce 1 pound of chicken. This includes the water for feed, drinking water, servicing facilities, and processing.

– The water footprint varies between conventionally-raised chicken versus organic/free-range chicken. Conventional chicken has a lower water footprint.

– The majority of water used for chicken production goes into growing the chicken feed, especially corn and soybean meal.

– Water usage also depends on the country and region in which the chicken is raised, due to differing farming practices.

Water Usage in the Chicken Supply Chain

Chicken production can be divided into three main stages, each of which requires significant water:

Feed Production

The first and most water-intensive stage is producing feed for the chickens. Chickens raised for meat are fed a high-protein diet, usually composed of corn and soybean meal. Producing the crops for chicken feed accounts for over 98% of the water used for chicken production.

Corn and soybeans have a high water footprint to grow. Corn requires between 108-150 gallons of water per pound, while soybeans require 216-300 gallons of water per pound.

So before a chicken even hatches, hundreds of gallons of water have already been used to grow its food.

Drinking Water

Over the 6-7 weeks that a broiler chicken is alive, it consumes a significant amount of drinking water. The precise amount can vary based on factors like weather and diet composition.

On average, an industry-standard broiler chicken will consume about 21 gallons of water during its lifespan. Free-range and organic chickens may consume a bit more due to their added movements and longer lifespan to market.

Water intake is essential for the chickens to maintain hydration, digest their feed, and support body growth. Proper water provision improves chicken health and the efficiency of feed conversion into meat.

Servicing Facilities

Large amounts of water are used in servicing chicken houses and processing facilities. Water applications include:

– Cleaning inside chicken barns – Surfaces are washed between flocks to disinfect facilities and reduce disease spread. Floors, walls, feeding systems, and other areas need regular cleaning.

– Employee sanitation – Hand washing facilities and restrooms for employees require steady water supply.

– Processing chickens – Water is used during scalding and defeathering, chilling chickens after slaughter, and sanitizing carcasses.

– Cleaning equipment – All equipment at processing plants must be thoroughly cleaned between batches of chickens.

– Temperature control – Water is circulated to control temperatures of chicken houses. Evaporative cooling pads may be used to cool incoming air.

Proper sanitation is crucial for chicken operations, both for food safety and biosecurity. Adequate water availability helps ensure proper hygiene.

Total Water Usage

Adding up the main components of water use gives an estimate of how much water is required per pound of chicken meat.

– Feed production: ~448 gallons
– Drinking water: 21 gallons
– Servicing facilities: ~3 gallons

So approximately 468 gallons of water goes into producing just 1 pound of chicken in typical commercial operations. Clearly feed production accounts for the vast majority of chicken’s water needs.

Factors Affecting the Water Footprint of Chicken

While 468 gallons per pound is a reasonable industry average, the precise water usage will vary based on several factors:

Conventional vs Organic/Free-Range Chicken

Production system has a major impact on water usage. Conventional chicken generally has a lower water footprint than organic or free-range chicken. Here’s why:

– Feed efficiency: Conventional chickens convert feed to meat more efficiently due to selective breeding. They require less feed per pound of weight gain, resulting in lower virtual water usage.

– Growth rate: Conventionally-raised broilers reach market weight significantly faster, in only 6-7 weeks rather than 12-14 weeks for slower growing breeds. Their shortened lifespan means less drinking water requirements.

– Housing: Organic/free-range chickens have lower stocking densities and access to the outdoors. More space per bird and outdoor ranges require greater water for cleaning and maintenance.

– Processing: Slower growth rates mean organic chickens require more water over their longer lifespan for processing procedures like scalding and chilling.

So while organic and free-range chickens have some sustainability benefits, their water footprint is estimated to be 1.5 to 2 times higher than conventional birds.

Geographic Location

The volume of water to produce feed crops like corn and soybeans depends heavily on the climate and irrigation practices of the agricultural region.

In drier Western states, producing feed crops requires far more irrigation water compared to the more rainy Midwest states. For example:

– Iowa corn: 108 gallons/lb
– California corn: 150 gallons/lb

So the location of feed crop production significantly influences the water needs of chicken farming. This should be taken into account when comparing water usage between countries as well.

Use of Byproducts in Feed

Reusing food industry byproducts in chicken feed, such as distillers grains from ethanol production or soybean hulls from oil processing, can substitute for feed crops and lower the water footprint.

Since byproducts do not require dedicated water use for crop production, incorporating them into feed formulas helps reduce the total water usage per pound of chicken.

Breed of Chicken

The genetics of the chicken plays a role as well. Modern broiler chicken breeds have been intensively selected for fast growth, which reduces their lifespan and total water intake.

Slower growing breeds, like those used for organic or pasture-raised chicken, require more water over their longer growth phase to reach harvest weight.

Comparison of Chicken’s Water Footprint to Other Meats

To put chicken’s water usage into perspective, it’s useful to compare it against other meat proteins.

Beef has a far higher water footprint than any poultry or pork. It takes around 1,800 gallons of water to produce one pound of live cattle.

– Beef: 1,800 gallons/lb
– Pork: 576 gallons/lb
– Chicken: 468 gallons/lb
– Turkey: 582 gallons/lb

Ruminant animals like beef cattle have lower feed efficiency and higher feed requirements, which greatly increases their virtual water needs for crop production. Overall, chicken has one of the lowest water footprints among commonly consumed meats.

Water Conservation in the Chicken Industry

The high water usage in chicken production means that opportunities for water conservation are also significant. Here are some steps the industry is taking to try reducing its water footprint:

– Breeding chickens for better feed conversion to reduce feed water needs

– Using recycled wastewater for producer operations whenever feasible

– Improving drinking water systems to avoid waste

– Upgrading cleaning systems in chicken houses and plants for efficiency

– Investigating alternative water sources like captured rainwater

– Returning nutrients in manure to crop fields to reduce need for irrigation

Adopting these measures can help make chicken production more sustainable as global water risks grow.

Conclusion

In summary, producing chicken is a water-intensive process, requiring about 468 gallons to raise each pound of chicken meat. The majority of this water is virtual water used in growing chicken feed crops. Variables like production system, location, and breed impact the total water footprint.

As concerns about water scarcity increase globally, the livestock industry faces challenges in minimizing its water use. Chicken production has lower water requirements than red meat, but still has significant room for improvement in water conservation practices. Sustainable solutions will be needed to ensure water resources can support future food production demands.
