Abstract

The invention discloses a piglet compound feed containing antimicrobial peptide for the later stage of nursery and a preparation method of the piglet compound feed. The compound feed is prepared from the following components in parts by weight: 58 to 61 parts of maize, 14 to 16 parts of bean pulp, 8 to 12 parts of imported DDGS (Distillers Dried Grains with Soluble), 5 to 8 parts of fermented soybean meal, 2 to 4 parts of glucose, 1.8 to 5 parts of imported fish meal, 0.4 to 0.8 part of calcium hydrophosphate, 0.15 to 0.2 part of lysine, 0.1 to 0.4 parts of table salt, 0.8 to 1.0 part of stone powder, 0.15 to 0.2 part of composite trace element premix, 0.10 to 0.15 part of rice bran, 0.08 to 0.10 part of methionine, 0.05 to 0.10 part of threonine, 0.03 to 0.10 part of choline, 0.02 to 0.05 part of composite multivitamin premix, 0.02 to 0.05 part of antioxidant, 0.01 to 0.03 part of plectasin antibacterial peptide, 0.01 to 0.03 part of cecropin and 0.02 to 0.05 part of plant essential oil complex. Proved by experiments, the antibacterial peptide feed disclosed by the invention can obtain body weight which is slightly higher than that of an antibiotic group and better feed rewards and has no influence on metabolism of piglets, body tissue proteinosis and an immunologic function. The piglet compound feed has important economic value and social value for ensuring piglet growth, intestinal health and food safety of human beings.

Description

technical field [0001] The invention relates to the technical field of animal nutrition and feed, in particular to a compound feed for piglets in the late nursery period containing antimicrobial peptides and a preparation method thereof. The feed is suitable for feeding piglets one month after weaning. Background technique [0002] Natural weaning generally occurs when piglets are around 3 months old. In actual production, in order to improve the productivity of sows and the utilization rate of farrowing houses, and reduce the vertical transmission from mother to piglets, pig farms usually choose to wean piglets around 3 weeks old. However, at this time, the digestive system of piglets is not yet fully developed, the secretion of gastric acid is insufficient, the volume and weight of digestive organs are relatively small, and the activity of various digestive enzymes is low. In addition, early weaned piglets have not yet established a stable intestinal microbial flora, and ...
