Fodder for sows in lactation period and preparation method thereof

Abstract

The invention relates to fodder for sows in the lactation period. The fodder is prepared from, by weight, 10-30 parts of animal-derived waste, 15-28 parts of bean dregs, 3-12 parts of cassava leaves,25-40 parts of corn, 0.1-0.3 part of methionine, 0.05-0.18 part of tryptophan, 1.5-2 parts of calcium hydrophosphate, 0.1-0.25 part of choline chloride, 3-8 parts of peptidic yeast extracts and 5-10 parts of composite microbial seed liquid. A strain combination of the composite microbial seed liquid is composed of mucor, aspergillus niger and trichoderma reesei. According to the fodder, the animal-derived waste is used as the main component of the fodder, abundant proteins and amino acids with high content in the fodder are efficiently utilized, the requirements of sustainable development aremet, the raising cost is reduced, the production benefits are increased, and environmental pollution can also be reduced. According to a nutrition complementarity principle, other auxiliary materialsare selected to be matched with the animal-derived waste, and the formed animal-derived fodder can provide balanced and sufficient nutrients for pigs, meet the requirements of the sustainable development, reduce the raising cost, increase the production benefits and also reduce the environmental pollution.

Description

technical field [0001] The invention belongs to the field of livestock breeding feed, in particular to a feed for sows during lactation and a preparation method thereof. Background technique [0002] With the rapid development of animal husbandry, the problem of lack of protein resources has become increasingly prominent. Livestock feathers, blood, and excrement are common by-products of poultry and livestock processing. At present, the feces, feathers, and blood produced in most slaughterhouses are not fully utilized, and are usually discharged as waste liquid or burned as waste, resulting in severe water and air pollution. [0003] Feather meal is processed from the feathers of livestock and poultry and the feather stalks left after velvet. It is rich in protein. The crude protein content can reach more than 80%, and the total amount of various amino acids is more than 70%. It is an important protein. resource. Blood meal is made by drying the blood obtained from slaugh...

Problems solved by technology

[0005] However, the main component of feather meal protein is disulfide-bound keratin (composed of parallel polypeptide chains in α-helix or β-sheet conformation, which is a water-insoluble protein that plays a protective or structural role), trypsin in animals , pepsin and other hydrolytic enzymes can hardly hydrolyze it, and feeding animals with raw feathers may even cause adverse reactions in animals

However, the nutrient content of blood meal is unbalanced, methionine and isoleucine are extremely lacking, the content of calcium and phosphorus is low, and the bloody smell it contains leads to poor palatability

In addition, the energy content of chicken manure is low, and the mineral content is unbalanced, especially the calcium content is too high. If it is not balanced with other components, feeding animals with chicken manure alone is likely to cause animal malnutrition.
