Comparison of Nutritional Value in Domestic Double-Low Rapeseed Meal and Imported Common Rapeseed Meal for Growing Pigs
摘要
Abstract
This experiment was conducted to compare the nutritional value in domestic double-low rapeseed meal and imported common rapeseed meal.Two experiments were conducted in this study.Experiment 1:eighteen castrated barrows with similar initial body weight of (48.3 ± 2.4) kg were used in a completely randomized design.The total collection method was used.The barrows were randomly allocated to 3 groups with 6 replicates per group and 1 pig per replicate.The barrows in 3 groups were fed a basal diet or two other experimental diets.The basal diet was formulated to meet requirements of growing pigs and two other experimental diets were formulated by substituting 20％ of the basal diet with domestic double-low rapeseed meal or imported common rapeseed meal,respectively.The test lasted for 14 days (9 day for adaptation and 5 day for collection).Experiment 2:eighteen castrated barrows (fitted with simple T-cannulas) with similar initial body weight of (35.3 ± 3.8) kg were used in this experiment.The indicator method was used.The barrows were randomly allocated to 3 groups with 6 replicates per group and 1 pig per replicate.The barrows in 3 groups were fed a N-free diet or two other experimental diets.The two experimental diets were formulated with domestic double-low rapeseed meal or imported common rapeseed meal as the sole source of protein and amino acids.The test lasted for 7 days (5 day for adaptation and 2 day for collection).The results showed that the apparent digestible energy and the apparent digestibility of energy in domestic double-low rapeseed meal were significantly lower than those in imported common rapeseed meal (P ＜ 0.01),and the apparent metabolizable energy in domestic double-low rapeseed meal was significantly lower than that in imported common rapeseed meal (P ＜ 0.05).The standardized ileal digestibility of amino acids in domestic double-low rapeseed meal was lower.In conclusion,the nutritional value in domestic double-low rapeseed meal is lower than that in imported common rapeseed meal.关键词
