双低菜粕浓缩料饲喂生长肥育猪效果研究

85头长大阉割仔猪随机分成3组,第1组为对照组,第2组和第3组为试验组。分别用"8800"、"华双三号"和"中双4号"浓缩料配合成全价饲料,于44～95kg期间进行饲养试验。结果表明:从入试—4月龄左右的试验前期,第1组、第2组和第3组的平均日增重分别为(858.63±153.86)g、(934.41±150.20)g和(895.84±170.33)g;3组的饲料利用率分别为2.74、2.48和2.52。后期各组平均日增重分别为(796±179)g,(685±139)g,(753±186)g;试验全期各组平均日增重(818±105)g、(793±91)g和(811±125)g;饲料利用率3.26、3.21和3.16。利用活体背膘测定仪Piglot105估测的瘦肉率,各组间差异不显著。试验表明利用双低菜粕生产的蛋白质浓缩料可以获得好的生产性能和经济效益。

A Feeding Trial of Growing-Finish pigs PIGS fed With Concentratrates Supplemented With Double-Low Rapeseed Meal

Eighty-five Landrace×Large White castrated piglets were alloted to three treatments at random.The the control diet (treatment 1)was comprised of No.8800,while the diets for experimental groups (treatment 2 and treatment 3)were combinated with concentrates supplented with double-low rapeseed meal from either Huashang No.3 or Chinese double -low No.4. A feeding trial was conducted at the period of 44 -95Kg bodyweight(BW).The results showed that in the growing period the average daily gain(ADG) of treatment1,treatment2,and treatment 3 was (858.63±153.86) g、(934.41±150.20)g and (895.84±170.33) g ,respectively (P>0.05);and the feed efficiency (FE) was 2.74、2.48和 2.52 respectively (P>0.05). In the fishing period ADG was (796±179) g,(685±139)g,(753±186) g(P>0.05) respectively.In the whole period ADG was(818±105) g、(793±91) g and (811 ±125)g (P >0.05);FC was 3.26、3.21 and 3.16 (P >0.05).The estimated lean percentage at the end of finishing period does have sigificant differences(P>0.05).
