摘要

本试验旨在探讨不同断奶重量对21日龄断奶仔猪生长性能、营养物质表观消化率、血清生化指标及肠道健康的影响。选取40头初生日龄相同、21日断奶的健康长×大二元杂交猪,分为L (5.0 ~ 5.5 kg)和H (6.5 ~ 7.0 kg)处理,每个处理5个重复,每个重复4头仔猪。两组被喂食相同的饮食。数据显示,断奶后21日龄高重仔猪的平均日增重显著高于低重仔猪(p 0.05)。绒毛高度(VH)、隐窝深度(CD)和VH:CD比(VRC)差异不显著,门、属水平肠道菌群相对丰度差异不显著(p < 0.05)。综上所述,仔猪21日龄断奶后的生长性能与其断奶重有关。

Effects of Different Weaning Weight on Growth Performance, Serum Biochemical Indices and Intestinal Health of Piglets.

A 3-week feeding experiment was conducted to explore the effects of different weaning weights on growth performance, apparent nutrient digestibility, serum biochemical indices, and intestinal health of piglets weaned at 21 days of age. Forty healthy (Landrace × Yorkshire) binary crossbred pigs with the same birth age and weaned at Day 21 were assigned to two treatments including L (5.0-5.5 kg) and H (6.5-7.0 kg), each with five replicates and four piglets per replicate. The two groups were fed the same diet. Data revealed that the average daily gain of high-weight piglets after weaning at 21 days was significantly higher than that of low-weight weaned piglets (p < 0.05); The crude fat (EE) and crude protein (CP) of H-piglets was significantly higher than that of l-piglets; There was no significant difference in the contents of total protein (TP), alkaline phosphatase (ALP), glutamic pyruvic transaminase (ALT), cholesterol (CHO), glucose (GLU), immunoglobulin M (IgM), triglyceride (TG), albumin (ALB), glutamic oxaloacetic transaminase (AST) and UREA between H-piglets and l-piglets after weaning at 21 days (p > 0.05). There was no significant difference in the villus height (VH), crypt depth (CD) and VH:CD ratio (VRC), and no significant difference in the relative abundance of intestinal flora at phyla and genus level (p > 0.05). In summary, the growth performance of piglets after weaning at 21 days is related to their weaning weight.

期刊介绍: As an international forum for hypothesis-driven scientific research, the Journal of Animal Physiology and Animal Nutrition publishes original papers in the fields of animal physiology, biochemistry and physiology of nutrition, animal nutrition, feed technology and preservation (only when related to animal nutrition). Well-conducted scientific work that meets the technical and ethical standards is considered only on the basis of scientific rigor. Research on farm and companion animals is preferred. Comparative work on exotic species is welcome too. Pharmacological or toxicological experiments with a direct reference to nutrition are also considered. Manuscripts on fish and other aquatic non-mammals with topics on growth or nutrition will not be accepted. Manuscripts may be rejected on the grounds that the subject is too specialized or that the contribution they make to animal physiology and nutrition is insufficient. In addition, reviews on topics of current interest within the scope of the journal are welcome. Authors are advised to send an outline to the Editorial Office for approval prior to submission.
