Compounded feed for adult meat chickens capable of lowering ammonia gas concentration of meat chicken houses

Abstract

The invention discloses a compounded feed for adult meat chickens capable of effectively lowering ammonia gas concentration of meat chicken houses. The compounded feed comprises the following ingredients in percentage by weight: 60% to 75% of corn, 6% to 12% of soybean meal, 5% to 10% of corn DDGS, 4% to 8% of cottonseed meal, 2% to 4% of pig meat and bone meal, 2% to 4% of lard oil, 2% to 5% of hydrolyzed feather meal, 0.6% to 1% of stone powder, 0.3% to 0.8% of dicalcium phosphate, 1% to 1.5% of special premix for adult meat chickens and 0.02% to 0.07% of plant extract premix, wherein the plant extract premix comprises 0.01% to 0.02% of Yucca plant extract, 0.02% to 0.03% of Lauraceae plant extract and 0.005% to 0.015% of garlic extract. Compared with the prior art, the compounded feed has the advantages that the requirements of growth of the adult meat chickens on nutrients are fully met on the basis of researching an ammonia gas generation mechanism of the meat chicken houses; andby adding the plant extract premix, the probability of generation of ammonia gas in the meat chicken houses is effectively lowered, and the culture loss is reduced.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to a compound feed for broiler chickens which reduces the ammonia concentration in a broiler house and a preparation method thereof. Background technique [0002] my country's poultry breeding volume and poultry egg output have been ranked first in the world for many years, and its poultry meat output is second in the world. At this stage, it is undergoing a transformation from a simple production method and low production efficiency to a modern, intensive and large-scale farming model. On the one hand, due to the significant progress in the establishment of standardized demonstration farms for large-scale livestock and poultry breeding, the planning and construction, technical capabilities and management levels of the broiler chicken industry have been significantly improved. On the other hand, experts at home and abroad have carried out a lot of research on environmental control p...

AI Technical Summary

Problems solved by technology

However, the daily growth capacity of chickens is limited, and they cannot convert all the protein and amino acids they eat into their own nitrogen source, and some of the nitrogen in the protein is still converted into ammonia gas emissions

At present, there is a shortage of protein resources in the world

[0005] Therefore, it is still an unsatisfied demand to develop a protein resource that can save feed raw materials, improve feed conversion rate, and reduce the ammonia concentration in the chicken house.
