| 摘 要： | 本试验通过添加植酸酶、有机酸(柠檬酸、抗坏血酸)和维生素D3、木聚糖酶来减少无机磷的添加量,提高饲料中植酸磷的利用率,降低磷的排泄量。选择30 kg左右的"斯格"纯种猪70头,随机分成7组:常磷组、低磷日粮组(NC)、NC+600 U/kg植酸酶组、NC+600 U/kg植酸酶+10 g/kg的柠檬酸、NC+600 U/kg植酸酶+10 g/kg的柠檬酸+200 mg/kg抗坏血酸、NC+600 U/kg植酸酶+10 g/kg的柠檬酸+200 mg/kg抗坏血酸+100μg/kg的维生素D3、不添加磷酸氢钙。所有日粮中都添加50 mg/kg木聚糖酶。结果表明:低磷日粮添加植酸酶、有机酸(柠檬酸、抗坏血酸)和维生素D3,平均日采食量无显著影响(P0.05),日增重显著提高(P0.05),料重比显著降低(P0.05);养分消化率均显著提高;血液指标着中,白蛋白显著降低(P0.05),碱性磷酸酶、总蛋白、谷草、谷丙转氨酶无影响(P0.05)。

| Abstract: | In order to improve the utilization of phytate P in feed to reduce phosphorus excretion,our current study was designed to add phytase,organic acids(citric acid,ascorbic acid),vitamin D3 and xylanase to reduce the amount of inorganic phosphorus addition.Seventy purebred pigs(scott) with an average initial weight about of 30 kg were randomly divided into 7 groups: control diets,low-phosphorus diets(NC),NC + 600 u/kg phytase,NC + 600 u/kg phytase + 10 g/kg citric acid,NC + 600 u/kg phytase + 10 g/kg citric aci... |
