水合硅铝酸钠钙对生长肥育猪生长性能、养分表观消化率及抗氧化能力的影响
Effects of Hydrated Sodium Calcium Aluminosilicate on Growth Performance,Nutrient Apparent Digestibility and Antioxidant Ability of Growing-Finishing Pigs
摘要
Abstract
This experiment was conducted to investigate the effects of hydrated sodium calcium aluminosilicate (HSCAS) on growth performance, nutrient apparent digestibility and antioxidant ability of growing-finishing pigs. A total of 45 healthy ' Duroc × Landrace × Yorkshire' growing-finishing pigs with an average body weight of (4. 08 ± 10. 0) kg were randomly allocated into 3 treatments with 5 replicates per treatment and 3 pigs per replicate. Pigs in control group were fed a basal diet, and the others in experimental groups were fed the basal diet supplemented with 0. 25% and 2. 50% HSCAS, respectively. The experiment lasted for 70 days and divided into two periods (48 to 80 kg and 81 to 110 kg). The results showed as follows; 1) compared with the control group, the addition of 0. 25% HSCAS to the diet had no significant effects on growth performance, serum urea nitrogen content and antioxidant ability of pigs (P >0. 05) , but significantly decreased the crude protein (CP) and energy apparent digestibility of pigs in 81 to 110 kg (P <0. 05). 2) Compared with the control group, the addition of 0. 25% HSCAS to the diet significantly increased the feed/gain in 81 to 110 kg and 40 to 110 kg, and significantly increased serum urea nitrogen content (P <0. 05) , but significantly decreased the apparent digestibility of CP, energy and crude ash, serum superoxide dismutase activity, and total anti-oxidation capability of pigs in 81 to 110 kg. The results indicate that the addition of 0. 25% HSCAS to the diet has no significant influence on the growth and health of growing-finishing pigs, but the addition of 2.50% HSCAS to the diet can significantly decrease the growth performance, nutrient apparent digestibility and antioxidant ability of growing-finishing pigs.关键词
