Application of Expanded Double-Low Rapeseed in the Diets of Lactation Sows
摘要
Abstract
The objective of this study is to explore the optimal proportion of expanded double-low rapeseed to add directly to lactation diets. Twenty-eight Landrace×Large White prepartum sows were assigned randomly into four groups in this experiment, with 7 in each group, and 1 as the replicate. Four diets with the same level of protein and energy were formulated to meet the NRC (1998) nutrient requirements through gradual increment of expanded double-low rapeseed levels (0%, 10%, 15%, 20%). The experiment period lasted for 28 days. The results showed that: 1) the average daily feed intake of the group of 10% expanded double-low rapeseed level was significantly higher than that of the control group, while the average daily feed intake of the group of 20% expanded doublelow rapeseed level was significantly lower than that of the control group (P＜0.05); 2) the body weight losses of 20% expanded double-low rapeseed group was significantly increased than that of the control group (P＜0.05); 3)the litter weight at the age of 28 days and litter weight gain from the age of 0 to 28 days of 20% expanded doublelow rapeseed level had significantly increased (P＜0.05); 4) the crude fiber and phosphorus digestibility of the group of 10% expanded double-low rapeseed level were significant higher than that of the control group (P＜0.05) ; and the apparent digestibility of nutritional ingredients in the control group was significantly higher than the group of 20% expanded double-low rapeseed level (P＜0.05); 5) it was found that the percentage of ALT, AST, T3, T4 and TSH had no significant differences among all groups versus the control (P＞0.05); 6) the milk solid, milk protein, milk fat in group of 20% expanded double-low rapeseed level was significant different (P＜0.05) than those in the control (P＞0.05). It was concluded that the optimum proportion of expanded double-low rapeseed added to the diets of lactation sows was from 10% to 15%, and the maximum proportion should not exceed 20%.关键词
