Abstract

Abstract A total of 120 21-day-old weaned piglets ((Yorkshire × Landrace) × Duroc) were used to evaluate the effects of dietary supplementation of diacylglycerol (DAG) on the growth performance, nutrient digestibility, fecal noxious gas emission, and hematology parameters in a 42-day experiment. All pigs were randomly assigned to three groups based on the initial body weight (6.47 ± 0.45kg). There were eight replicate pens per treatment and five pigs (three barrows and two gilts) per pen. The DAG in the levels of 0%, 0.05%, or 0.10% was used as supplement to the corn–soybean meal-based basal diet. Piglets fed the diet supplemented with graded levels of DAG linearly increased the average daily gain (ADG) during days 22–42 (P = 0.027) and 1–42 (P = 0.048). In addition, a tendency in the linear reduction of fecal ammonia (P = 0.095), hydrogen sulfide (P = 0.078), and methyl mercaptan (P = 0.085) emission was observed by increasing the DAG levels in the diet. However, feeding pigs with DAG-containing diet had no significant effects on the nutrient digestibility and hematology parameters. Therefore, the suitable dose of DAG used in the diet of weaned piglets was at 0.10% to improve ADG and reduce fecal gas emission.
饲粮中添加二酰基甘油对断奶仔猪生长性能、营养物质消化率、粪便有害气体排放和血液学参数的影响
摘要本试验选用120头21日龄断奶仔猪((约克×长)×杜洛克),研究饲粮中添加二酰甘油(DAG)对仔猪生长性能、营养物质消化率、粪便有害气体排放和血液学指标的影响。按初始体重(6.47±0.45kg)随机分为3组。每个处理8个重复猪圈,每个猪圈5头猪(3头母猪和2头后备母猪)。在以玉米-豆粕为主的基础饲粮中添加0%、0.05%和0.10%水平的DAG。饲粮中添加不同水平DAG的仔猪在第22-42天和第1-42天的平均日增重(ADG)呈线性增加(P = 0.027)。此外,随着饲粮中DAG水平的提高,粪氨(P = 0.095)、硫化氢(P = 0.078)和甲基硫醇(P = 0.085)排放呈线性减少趋势。饲粮中添加dag对猪的营养物质消化率和血液学指标无显著影响。因此,断奶仔猪饲粮中添加0.10%的DAG可提高日增重,减少粪便排放。

期刊介绍: Published since 1957, this quarterly journal contains new research on all aspects of animal agriculture and animal products, including breeding and genetics; cellular and molecular biology; growth and development; meat science; modelling animal systems; physiology and endocrinology; ruminant nutrition; non-ruminant nutrition; and welfare, behaviour, and management. It also publishes reviews, letters to the editor, abstracts of technical papers presented at the annual meeting of the Canadian Society of Animal Science, and occasionally conference proceedings.
