The Effects Of Performance On Jirong Rabbits And Economical Returns Were Analyzed Under Different Composition Of Diet

The effects of performance on Jirong rabbits and economical returns were analyzed under different composition of diet by this study . A total of 108 choiced Jirong rabbits of 50-day was raised 80 days and were divided to 9 groups,three rabbits and three duplicates each group.The composition of diet was included afalfa (50%, 60%, 70%,,80%), Legmus chinensis(50%, 60%, 70%, 80%) , corn meal (49%, 39%, 29%, 19%) and additives 1%, compared normal diet as control group .They were weighed at the time of 20th,40th,60th,80th days after beginning and butchered on the 80th day (one each group) .The performances , rates of abatage, areas of fur skin and densities of wool are detemined .The result shows :in the whole experiment period ,the day weight gains have been raised in 20-day .40-day.60-day. 80-day experiment period.Compared with control grop in the 20-day experiment period, afalfa â…  , afalfa â…¡, afalfa â…¢, Legmus chinensis â…£ have great distinctions (P<0.01);afalfaâ…£, Legmus chinensisâ… ,Legmus chinensis â…¢ havedistinctions(P<0.05);from the 21th to 40d, Legmus chinensis â…¡ has distinction (P<0.05), afalfa â… , afalfa â…£, Legmus chinensisâ…¢, Legmus chinensis â…£ have lower distinctions (P<0.05);from 41th to 60d, afalfa â… , afalfa â…¡, afalfa â…¢,afalfaâ…£ have great distinctions (P<0.01);from the 61th to 80d, Legmus chinensis III has great distinction(P<0.01), ), afalfa â…£, Legmus chinensis â… , Legmus chinensis â…£ have distinctions (P<0.05);Compared with control group in the 40dexperiment period , afalfa I has great distinction (P< 0.01), afalfall has distinction (P<0.05);in the 60d experiment period ,afalfall -. afalfa IIL afalfa IV have great distinctions (P<0.01), Legmus chinensisIV has distinction (PO.05);in the 80d experiment period , afalfa I s afalfall -. afalfa Illhave great distinctions (P<0.01);under the conditions of cutting down the feed-meat ratios ,the appetite each group has no distinction (P>0.05);as far as the areas of fur skin were concerned , afalfa I -. afalfa UK afalfa R/\ Legmus chinensis II > Legmus chinensisIV are higher than control groups and afalfa IV > Legmus chinensis IV have distinctions (P<0.05).The analytic results of economic returns shows that the cost of forages decreases by raising the ratios of asalfa and Legmus chinensis to the eight experiment groups. Composited every target , the economic returns of afalfa III are higher.
