本试验旨在研究钙、磷对免疫抑制仔猪生长性能、血液生理生化指标及矿物元素代谢的影响。选取18头22日龄“杜长大”三元杂交断奶仔猪(公母各占1 / 2),随机分为3组,每组6个重复,每个重复1头猪。其中,对照组和模型组饲喂基础饲粮,试验组饲喂含1.5倍NRC (2012)钙、磷标准的饲粮。试验第23天,模型组和试验组仔猪腹腔注射18 mg / kg BW伊立替康(CPT),连续注射4 d,用于建立免疫抑制仔猪模型,对照组注射等量生理盐水。试验期为28 d。结果表明:1)与对照组相比,腹腔注射CPT显著降低了仔猪的平均日增重(P

The aim of this study was to investigate the effects of calcium and phosphorus on growth performance, blood physiological-biochemical indices and mineral element metabolism of immunosuppressed piglets. Eighteen Duroc×Landrace×Yorkshire weaned piglets at 22 days of age were selected and randomly divided into three groups, each group consisting of six replicates with one piglet per pen. The control group and model group were fed a basal diet, while the experimental group was fed a diet containing a higher level of calcium and phosphorus [1.5 ti...
