摘要
This experiment was conducted to investigate the effects of fat sources on growth performance, nutrient digestibility, serum traits and intestinal morphology in weaning pigs. A total of 128 weaning pigs (LandraceLarge WhiteDuroc, days of age, of average initial body weight) were allotted in a randomized complete block (RCB) design with four treatments: 1) corn oil, 2) soybean oil, 3) tallow and 4) fish oil. Each treatment had 8 replicates with 4 pigs per pen. During phase I period (d 0 to 14), pigs fed corn oil or soybean oil diet tended to show higher ADG and FCR than any other treatments although there was no significant difference. During phase II period (d 15 to 28), pigs fed corn oil diet showed better ADG and ADFI than pigs fed soybean oil, tallow or fish oil. For overall period, growth performance of weaning pigs was improved (p<0.05) when pigs were fed soybean oil or corn oil. Apparent digestibility of energy and fat was improved when pigs were fed corn oil diet (p<0.05). Supplementation of corn oil resulted in higher serum triglyceride concentration than the other treatments (p<0.05). However, there was a lower cholesterol concentration when corn oil was provided compared to tallow or fish oil. Pigs fed corn oil tended to have increased villus height compared with soybean oil, tallow or fish oil treatment (p<0.05). This experiment suggested that vegetable oils such as corn oil or soybean oil, were much better fat source for improving growth performance of weaning pigs.

本实验旨在研究脂肪源对断奶仔猪生长性能，营养物质消化率，血清性状和肠道形态的影响。共有128只断奶仔猪（LandraceLarge WhiteDuroc，日龄，平均初始体重）分配在随机完全区组（RCB）设计中，有四种处理方法：1）玉米油，2）豆油，3）牛脂和4）鱼油。每次处理重复8次，每只猪4只。在第一阶段期间（d 0到14），饲喂玉米油或豆油饮食的猪比任何其他处理都显示出更高的ADG和FCR，尽管没有显着差异。在第二阶段期间（第15至28天），饲喂玉米油饲料的猪比饲喂大豆油，牛油或鱼油的猪表现出更好的ADG和ADFI。整个时期，断奶仔猪的生长性能得到改善（p 0。05）当猪喂食豆油或玉米油时。当饲喂玉米油饲料时，能量和脂肪的表观消化率得到改善（p 0.05）。补充玉米油导致血清甘油三酯浓度高于其他处理（p 0.05）。然而，与牛脂或鱼油相比，提供玉米油时胆固醇浓度较低。与豆油相比，饲喂玉米油的猪往往具有增加的绒毛高度，牛脂或鱼油处理（p 0.05）。该实验表明，植物油如玉米油或大豆油是改善断奶仔猪生长性能的更好的脂肪来源。
