Feed suitable for sows in perinatal period and piglets in lactation period and preparation method thereof

Abstract

The invention relates to the technical field of pig feed formulas, in particular to a feed suitable for sows in the perinatal period and piglets in the lactation period at the same time. The feed comprises the following formula: 10%-40% of puffed corn, 10%-30% of barley flour, 2.5%-18% of enzymolysis soybean, 1%-10% of whey protein concentrate, 0.5%-25.0% of whey powder, 0.5%-12.5% of glucose, 0.5%-12.5% of fructose, 1.0%-5.0% of super steam fish meal, 0.05%-1% of lysophospholipid, 1%-5% of puffed flaxseed, 0.2%-2.5% of deep sea fish peptide, 0.2%-1.0% of sodium chloride, 0.1%-0.2% of egg yolk antibody, 0.02%-0.05% of yucca extract, 0.1%-1.0% of 1-glycerol monobutyrate, 0.2%-2% of bovine colostrum, 0.5%-1% of calcium formate, 0.5%-0.8% of calcium hydrogen phosphate, 0.03%-0.05% of compound vitamins and 0.2%-0.4% of compound trace elements. The feed can shorten the birth process of sows, reduce the stillbirth rate, reduce the diarrhea rate of piglets and improve the weaning litter weight.

Description

technical field [0001] The invention relates to the technical field of pig feed formula, in particular to a feed suitable for both perinatal sows and lactating piglets. Background technique [0002] Most nutritional research on breeding sows has focused on effects during gestation or lactation, with little research on the transition from late gestation to lactation. From the 95th to 105th day of gestation until the sow is about to give birth, the secretion in the milk alveolar cavity of the sow increases significantly, and the mammary acinus gradually begins to secrete and accumulate milk. The third stage of rapid mammary gland development is after the sow gives birth. Stimulated by the piglet arching the sow's teat with its nose and the piglet sucking the teat, and with the continuous secretion and accumulation of milk by the sow's mammary gland acinus, the weight of the sow's mammary gland continues to increase until about the 21st day of the sow's lactation period Gradua...

Problems solved by technology

However, the energy concentration in the feed of sows in the late pregnancy is too high, resulting in excessive fat deposition in the mammary glands and milk ducts of sows, and the occurrence of insufficient lactation or sudden angalactia after farrowing

At this time, there is a need for a lactation-promoting product that provides high-efficiency energy, high-quality protein, balanced fat, and an appropriate amount of dietary fiber for the sows during the perinatal period (5 days before and 5 days after farrowing), so that the sows’ small intestine The proportion of absorbed glucose, lactic acid and fat is increased, and the proportion of short-chain fatty acids (SCFA) absorbed by the hindgut is reduced, thereby alleviating the sow’s use of its own fat reserves during lactation, severe weight loss, and affecting the success rate of conceiving the next litter
