Study On Technology And Optimization Of The Key Links In Large-scale Production Of Meat Rabbit

Rabbit industry in our country is in a critical stage of the transformationfrom traditional farming to intensive factory farming. This study based on the rabbit production status, focus on the following parts in commodity rabbit production including: feed nutrition, breeding mode, estrus synchronization, weaning weight and feeding mode, aims to improve meat rabbit breeding scale, conservation, the level of modern farming, and eventually obtain the biggest economic benefits.Feed nutrition test showed that the optimal diet suite to HYLA female rabbits in the All in All out mode to promote reproductive female rabbit lactation is as followings:crude Protein is the 17~18%, digestible energy is 10.5MJ/kg ~ 11 MJ / kg, crude fiber level is about 13% and the lysine level is about 1%.Breeding pattern contrast test showed that in the All in All out mode 35 day old weaning survival rate, 70 days of age fattening survival rate were all significantly higher than that of traditional breeding mode(P < 0.01).Estrus synchronization test showed that the mother rabbit estrus synchronization optimal light processing: breeding 7 days before light, day light 16 h, after mating 7 days dimming; under the premise of light plus breeding, without the injection of the hormone, oestrus rate remains high.The weaning weight contrast test showed that: with higher weaning weight, slaughter weight gets higher, which is more conducive to the promotion of the economic benefits.Feeding experiment showed that slaughter weight inad libitum feeding group was significantly higher than that of restricted feeding group(P < 0.01), feed meat ratio of restricted feeding group(3.09) was significantly lower than ad libitum feeding group(404)(P < 0.01). Each rabbit income of ad libitum feeding group was significantly lower(3.86 yuan) than that of restricted feeding group. Different feed amount was not significant on survival rate of litters; slaughter weight with restricted feeding reduction showed a trend of decrease, reasonable range of restricted feeding for fattening rabbits breeding efficiency improvement is very obvious, in different regions, different varieties and different seasons we should follow different feed standard feeding fattening rabbits.
