A comparison between tianfu black rabbit and new zealand rabbit in growth rate and feed conversion efficiency 天府黑兔新品系与新西兰兔生长发育规律及饲料转率的比较研究
An increase in the metabolisable energy and improvement in feed conversion are important factors for poultry producer 对于家禽饲养者而言,代谢能的增加和饲料转化率的改善是相当重要的因素。
The growth and the feed conversion were improved by adding multienzyme in the miscellaneous meal diet for fattening pigs 在杂粕型日粮中添加杂粕溢多酶,能提高肥育猪的生长速度和饲料转化率。
Results of the performance tests show an average improvement of at least 2 % of the feed conversion , depending on species 动物生产性能试验结果表明,根据畜禽种类不同,加酶后饲料转化率平均至少提高2 % 。
A recent test with layers fed corn - based diets demonstrated a significant reduction of feed consumption resulting in a noteworthy decrease of feed conversion by 5 . 8 % 最近对饲喂玉米基础日粮的蛋鸡试验表明,饲料消耗量的显著减少,饲料转化率改善5 . 8 % 。
When the same amount of multienzyme was added in the diet with different contents of miscellaneous meals , the daily gain and the feed conversion were higher with lower content of miscellaneous meals 在不同杂粕含量的日粮中添加相同量的杂粕溢多酶,杂粕含量少的日增重高,饲料转化率也高。
When the content of miscellaneous meals in diet is the same and the adding amount of a yiduo multienzyme was different , the daily gain of pigs and the feed conversion were improved with the increase of adding amount of multienzyme 摘要日粮中杂粕含量相同而杂粕溢多酶添加量不同时,肥育猪日增重和饲料转化率随著杂粕溢多酶添加量的增加而提高。
The results of this experiment showed that the nutrition level had a certain effect on weight gain , feed conversion rate and lactation weight loss in every stage during gestation , and the effect of metabolic weight and average daily feed intake on sow ' s gestation weight gain during early days of gestation period was significant ( p < 0 . 05 ) 结果表明,不同的营养水平影响到妊娠各阶段增重、日增重和料肉比以及泌乳损失,妊娠前期代谢体重、日均采食量对泌乳损失的影响显著( p < 0 . 05 ) 。
Bs of different dosages simultaneously inoculated rabbit with inactivated vaccines of rabbit hemorrhagic disease virus ( rhdv ) . the hi liters of antibody against rdhv induced by rdhv inactivated vaccine in the group of high dosage bursin are higher than control group about 2 - 3 liters averagely . and the result of t - lymphocyte transformation assay shows that the bursin can temporarily enhance the t - lymphocyte transformation . the results of effects of bursin on body weight gain and feed conversion ration in rabbits show that bs can increase growth of mammal . the effect of bursin has a relation to its dosage , but has no ralation to the difference of interspecies and the method which come into the body 试验中还发现, bs对鸡体有一定的增重作用从而提高了饲料报酬。将不同剂量bs与兔瘟灭活苗同时免疫家兔,高剂量的dbs 、 cbs组可使兔瘟hi抗体水平较免疫对照组提高2 - 3个滴度。 t -淋巴细胞转化试验表明: bs可短暂促进t -淋巴细胞的活化。
