Effection Of Production Performance Of Mutton Merino Sheep By Adding Micro Ecological Feed In Diets

China is the world's largest mutton sheep producer,which sheep scale is about 300 million.The northeast of China is Very important fine-wool sheep region in history.In recent year,because the scale of mutton merino sheep rapidly increased by hybridizing local fine-wool sheep with German mutton merino sheep and South African mutton merino sheep,it become one of optimization model of the hybridization combining with meat and wool.This study select the mutton merino sheep to evaluate comprehensive production performance through the production data collection and analysis of it.The administration of monensin,Twain 80,zymin,panaxoside and enzymes living bacterium inhibitors to mutton merino would combine open-circuit calorimetry chambers,growth test and slaughter experiment to analyze the different the effect of microecological feed on population growth,slaughtering,meat and other comprehensive production performance,aiming to supple the data for The mutton sheep breeding and hybrid improvement applications in Jilin province.The results showed that the meat performance of mutton merino sheep was better than that of northeast fine wool sheep and small tail sheep.Diet adding Monensin ?Tween 80?Mixed enzyme preparation?Panaxoside?Ferment and so on Mic-feed preparation,Significantly improve the early mutton Merino sheep ADG,but no significant difference in the whole period ADG.Significantly improve the specificity of flavor substances 4-methyl nonyl acid content;In stress state,the average daily gain is 184.90 g in adding Panaxoside,and 208.33 g in adding Ferment,which is Significantly higher than the control group 170.30 g,anti stress effect remarkable;Mixed enzyme preparation group was significantly lower than the control group in crude fat content,the water content was higher than the control group.Micro ecological feed preparation can be used for Mutton Merino sheep early growth and meat quality control and anti stress.
