摘要

本试验旨在研究饲粮中添加藜皂苷(QS)和海藻(SW)对断奶仔猪生长性能、粪便评分和气体排放的影响。选取120头21日龄杂交([约克×长白]×杜洛克)断奶猪,随机分为3个处理组。这些饲粮处理包括(1)TRT1: CON(基础饲粮)、(2)TRT2: CON + 200 mg/kg QS和(3)TRT3: CON + 500 mg/kg SW。根据猪的体重和性别,每处理10个重复栏(每栏2公,每栏2母)饲养5周。QS的加入显著(p <0.05)提高了全期平均日增重(ADG)和平均日采食量(ADFI)。此外,在第1周和第5周,添加QS有增加ADG的趋势,而在第1周,与CON相比,添加QS有增加ADFI的趋势。然而,在整个试验过程中,饲料系数、粪便评分和气体排放均未表现出显著的影响。综上所述,QS对断奶仔猪的生长性能有有益影响,对仔猪的气体排放和粪便评分无负面影响。

Inclusion of dietary Quillaja saponin and seaweed on growth efficiency, noxious gas emissions, and fecal score in weaning pigs
This study aimed to investigate the dietary effects of Quillaja saponin (QS) and seaweed (SW) on growth performance, fecal score, and gas emissions in weaning pigs. A total of 120, 21-day old crossbred ([Yorkshire × Landrace] × Duroc) weaning pigs were randomly assigned to three treatment groups. These dietary treatments consisted of (1) TRT1: CON (basal diet), (2) TRT2: CON + 200 mg/kg QS, and (3) TRT3: CON + 500 mg/kg SW. Pigs were raised in 10 replicate pens per treatment (two males per pen and two females per pen) for 5 weeks based on body weight and sex. The inclusion of QS significantly ( p < 0.05) increased average daily gain (ADG) and average daily feed intake (ADFI) during the overall period compared to the control diet. Moreover, the tendency to increase ADG was found at weeks 1 and 5, whereas ADFI showed a tendency to increase at week 1 with the supplementation of QS compared to the CON diet. However, the feed conversion ratio, fecal score, and gas emission failed to show significant effects throughout the experiment. In summary, QS has a beneficial effect on the growth performance of weaning pigs without any negative effect on gas emission and fecal score.

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.
