Gmos Is A Meat Rabbit Production

It has become clear over the last decade that non-digestible oligo sacchar ides (NDO) are likely to play a variety of physiological and nutritional roles in improving gut microflora, enhancing body immunity, regulating endocrine secretion and increasing nutrient availability potentially, which broaden the traditional function of NDO. As a non-nutritional regulator, NDO has extensive prospect among dietary antibiotic replacements. This study was conducted to evaluate the effects of GMOS on growth performance, immune index, meat quality, butcher index, PH in stomach and intestianl and the using ratio of nutrition on New zealand rabbits.Seventy-two 35-d-old New Zealand rabbits were divided into three groups with three replicates, each of which including 8 rabbits, in a randomized block design. The complete breed rule was divided into two scheduled times: 35—50-d-old and 50—70-d-old. The whole test expect was 35 days. The three groups were fed with same basic diet, group blank contains 0%; group antibiotic contains 0.005% olaquindox; group CMOS contains 0.5% GMOS in prophase and 0.25% GMOS in anaphase. Weight measure in every week, feed intake were measured in everyday, digestible ratio were measured in per test. The meat quality, immunity index and butcher ratio all were mensurated in the end of the test.The results as follows:1. Compared with group blank and group antibiotic, the mortality ration and the diarrhea frequencies in group GMOS all were decreased (P<0. 05) in two tests.2.35—50-d-old, the average daily gain(ADG) in group GMOS was higher than group blank and group antibiotic (P<0. 05) ;the average daily feed in take(ADFI) in group GMOS was higher than group blank (P<0. 05) and group antibiotic (P>0. 05). Feed gain(F/G) in group GMOS was lower than group blank and group antibiotic (P>0. 05) . 50-70-d-old, ADG in group GMOS was lower than group blank and group antibiotic (P>0. 05) ;ADFI in group GMOS was lower than group blank and group antibiotic (P<0. 05) ;F/G in group GMOS was lower than group blank and group antibiotic (P>0. 05) .3. PH in cecum and duodenum between in'group GMOS were significant lower group blank (P<0. 05) ;there were no significant difference between gr...
