Low-carbon environment-friendly conservation-stage piglet feed

Abstract

The invention discloses low-carbon environment-friendly conservation-stage piglet feed. Based on physiological characteristics of conservation-stage pigs, multiple raw materials are combined with one another, the nutrients are complementary, the protein content of the feed is about 16 percent, functional additives such as phytase, a compound enzyme preparation, a compound acidifying agent, a compound microecological preparation and oligosaccharide are added into the piglet daily ration, the growth performance is the best, the apparent digestibility of the crude proteins is the highest, a feed conversion ratio is the lowest, and the content of nitrogen and phosphorous in fecaluria is the lowest. Compared with a control group which has the high protein content (19%) and is free of functional additives, the feed provided by the invention has the advantages that the apparent digestibility is improved by about 10 percent, the feed conversion ratio is reduced by about 9 percent, and the nitrogen content in fecaluria is reduced by 38 percent; compared with daily ration which has the protein content of 17-18 percent and contains a certain amount of functional additives, the feed provided by the invention has the advantages that the apparent digestibility is improved by 10 percent, the feed conversion ratio is reduced by 1.8 percent, and the nitrogen content in fecaluria is reduced by 25-35 percent. Therefore, after a certain amount of additives are added in the low-protein amino acid balanced daily ration, the apparent digestibility of piglet to crude proteins is obviously improved, the feed conversion ratio is reduced, the emission of N and P in the fecaluria is reduced, the production performance of piglets is greatly improved, the environmental pollution is effectively reduced, and the requirements of low carbon and environment friendliness are met.

Description

technical field [0001] The invention relates to the field of animal feed, in particular to a low-carbon and environment-friendly feed for piglets in the nursery period. Background technique [0002] Piglet production is the primary link in large-scale pig production. Improving piglet production capacity is the key to increasing economic benefits of pig raising. High piglet survival rate is the goal pursued by every farmer. However, due to the rapid growth and strong appetite of the piglets in the nursery period, the internal organs are not fully developed but the burden is too heavy, the active immune system cannot develop synchronously, resulting in a sharp decline in maternal antibodies after weaning, the body's resistance is relatively poor, and many diseases are prone to occur. At present, some feed mills and farmers design high-protein formulas in order to pursue high production capacity, and some unabsorbed amino acids will be excreted from the body, resulting in exces...

Problems solved by technology

However, due to the rapid growth and strong appetite of the piglets in the nursery period, the internal organs are not fully developed but the burden is too heavy, the active immune system cannot develop synchronously, resulting in a sharp decline in maternal antibodies after weaning, the body's resistance is relatively poor, and various diseases are prone to occur

At present, some feed mills and farmers design high-protein formulas in order to pursue high production capacity, and some unabsorbed amino acids will be excreted, resulting in excessive nitrogen emissions and waste of protein resources.

At the same time, excessive antibiotics, heavy metals, etc. are added, causing environmental pollution
