【摘要】：為了探討復合微生態(tài)制劑對藏香豬育肥增重的影響,試驗選擇60日齡斷奶、體重(12.71±0.33)kg藏香豬斷奶仔豬90頭,隨機分為3組,每組30頭。1組飼喂基礎日糧+0.1%復合微生態(tài)制劑,2組飼喂基礎日糧+抗生素,3組飼喂基礎日糧。試驗期120 d。結(jié)果表明:藏香豬3,4月齡體重1組顯著高于2,3組(P0.05);5月齡體重1組2組3組(P0.05);6月齡體重1組3組2組(P0.05);藏香豬2~≤3月齡的日增重1組顯著高于2組、3組(P0.05);3~≤4月齡、4~≤5月齡的日增重各組間無顯著差異(P0.05);總采食量、平均日采食量、平均日增重、料重比均為1組3組2組。說明在本試驗條件下,藏香豬2,3,4月齡時在基礎日糧中添加0.1%復合微生態(tài)制劑可促進其生長發(fā)育,提高日增重,降低料重比,且效果優(yōu)于抗生素。
[Abstract]:In order to study the effect of compound microecological preparation on weight gain of Tibetan Xiang pigs, 90 weaned piglets with body weight of (12.71 鹵0.33) kg were randomly divided into 3 groups. Each group of 30 head .1 group was fed with basal diet 0.1% compound microecological agent and group 2 was fed with base diet antibiotic group 3 groups were fed basic diet. The experiment period was 120 days. The results showed that the weight gain of Tibetan Xiang pigs in group 1 was significantly higher than that in group 2 (P0.05) and that in group 1 was significantly higher than that in group 2 (P0.05). There was no significant difference in daily gain between groups of 4 ~ 鈮，
