Manure Production: Chickens' Astonishing Output

Chicken manure is a valuable byproduct with a high nutrient content, making it a great natural fertilizer. On average, a chicken will produce approximately 0.5 pounds of fresh manure per pound of feed consumed. This can vary depending on the breed and feeding habits of the chicken, with industrial hens producing about a quarter-pound of manure per day, and heritage breeds producing about half of that.

Industrial hens produce about a quarter-pound of manure per day

Chicken manure is an excellent natural fertilizer for gardens and crops due to its high nutrient content. It contains all the essential nutrients required for crop production, including potassium and phosphorus, and has been used for this purpose for centuries. In addition to its nutritional benefits, poultry fertilizer can also increase the soil's water infiltration rates by improving its structure and increasing soil organic matter content.

The amount of manure produced by a chicken depends on various factors, such as breed, feed consumption, and management programs. According to Commercial Meat and Egg Production, industrial hens produce about a quarter pound of manure per day. This estimate is based on the amount of feed consumed by these hens, which is typically higher than that of heritage breeds due to their breeding for maximum production under controlled environmental conditions.

Comparatively, estimates from the early 20th century suggest that pre-industrial chickens produced about half as much manure as their modern counterparts. For example, according to Morrison's Feeds and Feeding, 200 chickens would produce approximately 8,500 pounds of manure per year, averaging about 0.116 pounds per chicken per day. However, it is important to note that modern industrial hens are likely to have higher manure production due to their increased feed consumption.

Manure production can vary significantly depending on the management programs in place. On-farm records are the most accurate way to determine manure production for each operation. For example, in Georgia, manure production estimates for different types of poultry operations are as follows: 2.5 pounds per broiler, 20-30 pounds per commercial layer, 44 pounds per broiler breeder, and 8 pounds per replacement pullet. Proper management of poultry manure through nutrient planning can help maximize its benefits and address any potential environmental concerns.

Manure production varies with management programs

According to Commercial Meat and Egg Production, industrial hens produce about a quarter pound of manure per day. This number was calculated based on the amount of feed consumed by the hens. Because these hens are bred for maximum production, they consume more feed and probably produce more manure.

In contrast, pre-industrial chickens produce less manure. For example, according to Morrison's Feeds and Feeding, 200 chickens produce about 8,500 pounds of manure per year, which is about 0.116 pounds per chicken per day.

To maximize the nutrient value of poultry litter, it should be incorporated into the soil immediately after spreading. Forty to 70% of the total nitrogen is available during the first six weeks, and the remaining nitrogen is slowly released as organic residues decompose. Poultry manure can also increase the soil's water infiltration rates and short-term organic matter content.

Manure has a gross value of over $60 million

Chicken manure is a valuable resource, and it has been recognised for centuries as an organic fertilizer and a source of plant nutrients. A chicken produces approximately 0.5 pounds of manure for every pound of feed consumed. This manure has a high moisture content of about 75%, but it rapidly loses water through evaporation, and the final product has a moisture content of 20-40%. Manure production can vary depending on management programs and bird-related factors, but on average, it is estimated that 2.5 pounds are produced per broiler, 20-30 pounds per commercial layer, 44 pounds per broiler breeder, and 8 pounds per replacement pullet.

The value of chicken manure lies in its nutrient content, which includes potassium and small quantities of other elements. It is an excellent source of plant nutrients and can increase the soil's water infiltration rate and soil organic matter content in the short term. This makes it a beneficial product for crop production. In Georgia, for example, the yearly poultry production results in an estimated 1.3 billion broilers, 12 million commercial laying hens, 11.8 million broiler breeder hens, and 12 million replacement pullets. The manure produced by these birds has a potential gross value of more than $60 million.

The economic benefit of chicken manure can be significant, especially when effectively marketed and managed. The average delivered cost for commercial operators is $20 per ton of broiler litter, and proper nutrient management can further enhance its value. For example, incorporating litter into the soil immediately after spreading can increase its nutrient availability, with 40-70% of total nitrogen becoming available in the first six weeks.

Chicken manure is also the basis for several fertilizers. Companies like Seven Springs Farm Supply offer poultry manure fertilizers, such as Everlizer, Sustane, and Harmony Ag Organic Fertilizer, which are marketed and sold to farmers. These fertilizers are often sold in large quantities, with full truckloads or tons available for purchase. The cost of these fertilizers can vary, with prices ranging from a few thousand to tens of thousands of dollars, depending on the brand and formulation.

In summary, chicken manure is a valuable resource with a gross value of over $60 million, as demonstrated by its essential role in crop production and its potential for generating economic benefits through effective marketing and nutrient management. Its nutrient content, ability to improve soil structure, and wide availability make it a sought-after product in the agricultural industry.

Manure has a moisture content of 75% initially

Chicken manure is a valuable byproduct, and it can be used as a fertilizer due to its high nutrient content. On average, a chicken will produce approximately 0.5 pounds of fresh manure per pound of feed consumed. This manure has a moisture content of about 75% initially. This moisture content is important to consider as it affects the weight and volume of the manure, as well as its potential uses and applications.

The high moisture content in chicken manure is mainly due to the water content in the feed consumed by the chickens. The water is necessary for the digestion process and is also used to regulate the bird's body temperature through panting and perspiration. The moisture content in manure can vary depending on several factors, including the bird's diet, water intake, and environmental conditions. For example, chickens that consume more water in hot weather may have higher moisture content in their manure.

As the fresh manure sits, it rapidly loses water through evaporation. This evaporation process reduces the moisture content to a range of 20-40%. The final moisture level depends on factors such as bedding type and quantity, bird concentration, watering equipment, and ventilation systems. Therefore, while the initial moisture content is high, the final moisture content of chicken manure can vary significantly depending on various factors.

Chicken manure with a lower moisture content is easier to handle and transport. This is because high-moisture manure is heavier and more challenging to process and apply to fields or gardens. Additionally, the lower moisture content helps preserve the nutrients in the manure, making it a more effective fertilizer. Therefore, while chicken manure initially has a high moisture content, this decreases over time, and the final moisture level can be managed to some extent by controlling environmental factors.

Broilers produce 2.5 pounds of manure

The large quantity of manure produced by broilers can present a disposal problem for producers, especially considering the bedding used for the birds, which adds to the bulk. The average delivered cost for commercial operators is $20 per ton of broiler litter, so effective marketing can make poultry litter economically beneficial for growers.

The moisture content of the final product is typically between 20-40%, depending on factors such as bedding type, bird concentration, and ventilation systems. To maximize the nutrient value of poultry litter, it should be incorporated into the soil immediately after spreading, as 40-70% of the total nitrogen is available during the first six weeks.

Estimates of manure production per 1000 broilers vary, with Parker et al. (1959) estimating 621.4 kilograms, Hamm (1966) citing over 2,722 kilograms of litter, and Pfost (1960) stating around 2,041 kilograms of dry droppings for a ten-week rearing period. These estimates may be based on smaller birds or longer rearing periods than those used on present-day broiler farms.
