Problems solved by technology

However, studies have shown that broiler chickens are exposed to low-concentration hydrogen sulfide for a long time. They are first stimulated by hydrogen sulfide, causing ophthalmia and respiratory symptoms. 3+ Combined, the inactivation of enzymes will cause tissue hypoxia, which can lead to weakened chickens, decreased immune function, and even chronic poisoning
It can be seen that broilers are exposed to such a low-concentration hydrogen sulfide environment for a lifetime, which will seriously endanger their health, which will inevitably lead to a decline in productivity, and will also have a negative impact on the quality and safety of poultry meat.

Abstract

The invention discloses broiler feed capable of reducing emission of hydrogen sulfide. According to the broiler feed, corn is selected as an energy raw material, and a part of soybean meal is replaced with cottonseed meal and peanut kernel meal in a proper proportion. The use amount of sulfur-containing amino acid methionine is reduced, and the synthesis action of an animal body is enhanced by adding betaine and increasing the use amount of reinforced choline chloride, folic acid and the vitamin B12, so that growth needs are met. By adding an enzyme preparation, prebiotics and antibacterial peptide (limulus), the immunity of the intestinal tract and the health level of the intestinal tract are improved, and the absorption and utilization rate of the intestinal tract to nutrients including sulfur is promoted. Therefore, the developed feed can promote the growth of broilers, improve the sulfur utilization rate of the feed and reduce emission of hydrogen sulfide in the breeding process.

Description

technical field [0001] The invention belongs to the field of animal nutrition and relates to a feed, in particular to a broiler feed which reduces hydrogen sulfide emission. Background technique [0002] Hydrogen sulfide is a harmful gas produced by the fermentation of manure in the process of large-scale farming, and its harm is no less than that of ammonia. Broiler chicken breeding in my country has a high degree of scale. The number of broiler chickens in a house is generally 30,000 to 50,000. The output of manure is large, and the fermentation of manure produces a lot of harmful gases. Because the concentration of hydrogen sulfide in the chicken house is not as high as that of ammonia gas, it often does not attract people's attention and does not realize the harm of hydrogen sulfide. However, studies have shown that broiler chickens are exposed to low-concentration hydrogen sulfide for a long time. They are first stimulated by hydrogen sulfide, causing ophthalmia and re...
