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.
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.
