Feed capable of improving henhouse environment and increasing dietary protein utilization rate

Abstract

The invention discloses a feed capable of improving a henhouse environment and increasing dietary protein utilization rate. Various raw materials in a compound feed with different dietary protein levels are as follows: 55-65 % of corns, 3-8% of flour, 1-5% of corn protein powder, 2-6% of corn distillers' grains, 4-30% of soybean meal, 3-6% of peanut meal, 3-6% of rice bran meal, 2-5% of rapeseed meal, 1-9% of plant oil, 0.2-0.4% of salt, 1-2% of mountain flour, 0.2-1.5% of calcium hydrophosphate, 0.05-0.15% of choline chloride, 0.08-0.2% of methionine, 0.06-0.15% of threonine, 0.3-0.8% of lysine, 0.01-0.015% of phytase, 0.2-0.3% of vitamin premix, 0.2-0.3% of trace mineral premix, a Yucca shidigero extract and a protease preparation. The feed disclosed by the invention has the advantages of scientific mixing ratio and simplicity for making; because the Yucca shidigero extract and the protease preparation are added to a broiler feed formula, the broiler dietary protein utilization rate is increased, the ammonia concentration in the henhouse is reduced and the environment condition of the henhouse is obviously improved; meanwhile, no negative effect is generated on the broiler growth performance.

Description

technical field [0001] The invention relates to animal breeding feed containing raw materials derived from plants, animals or minerals, in particular to a feed that reduces the ammonia concentration in poultry houses, improves the utilization rate of dietary protein, and improves the growth performance and intestinal health of broilers. Background technique [0002] Modern intensive feeding methods lead to an increase in the breeding density of broilers, and in cold seasons, in order to keep warm, the ventilation of poultry houses is often small, resulting in relatively high temperature and humidity in poultry houses. The utilization rate of protein feed by poultry is low, and undigested feed nutrients are excreted in the form of excrement. These excreta are fermented and decomposed in a high-temperature and high-humidity environment, which can produce a large amount of odorous gases such as ammonia and hydrogen sulfide. Ammonia is the most harmful gas in chicken coops. It c...

AI Technical Summary

Problems solved by technology

[0003] At present, the broiler breeding industry in my country mainly focuses on the improvement of growth performance, and pays little attention to the utilization rate of dietary protein, harmful gas pollution in the chicken house environment, and broiler health. Especially in the late growth period of broiler chickens, the ammonia concentration in the house increases significantly. Can achieve frequent ventilation, and the effect of reducing ammonia emissions is not obvious
