| In our country, the development of feed industry of Rabbit was far behind lagged compared to other livestock and poultry . Many problems need to be solved urgently. The most prominent point was the problems of feed nutrition standards. At present there is no uniform nutritional standard for rabbits. Many materials introduced the standard of the United States, Germany and France, but our rabbit production was always based on the NRC feeding standards, the nutrition standard of rex rabbit from Gu zilin in 1998 and recommended feeding standards of French kerry mo breeding company. Combining the status of domestic, professor GuZiLin of Agricultural University of Hebei Based on many years of raising experience summarized a set"one feeding of whole"of breeding method.This experiment was conducted with three different models to study the effect. Experiment 1: Sixty nursing Rex Rabbits which were parturition synchronization, healthy, similar weight were selected and divided into three groups(â… ,â…¡,â…¢) randomly, twenty Rex Rabbits in each group. They were fed with different diets according to three feeding standard of NRC, French kerry mo and"one feeding of whole". After 30 days experiment, effects on milk performance, nutrition digestibility, weight change of female rabbits, growth and development of young rabbit were studied. The experiment results showed that:(1)Under the three models, 21 day-lactational performance and weaning rabbit weight of groupâ…¡were higher obviously than the groupâ…¡( P <0. 05), Weaning young rabbits survival rate of the groupâ…¡was higher obviously than the groupâ…¡andâ…¡( P <0. 05);(2) The body weight of the nursing rabbits in groupâ…¡andâ…¡can recover to the weight level of postpartum weight after weaning, but the groupâ…¡did not;(3)Feed intake for the nursing rabbits of groupâ…¡was higher obviously at the period of 0 to 10 days than the groupâ…¡, and at the period of 11 to 20 days was higher obviously than the other two groups, but at the period of 21 to 30 days, feed intake of the groupâ…¡was higher obviously than the groupâ…¡andâ…¡;(4) The nutrition digestibility at the 20th day of groupâ…¡was higher obviously than groupâ…¡andâ…¡( P <0. 05).Experiment 2: Test was continued after the first one, young rabbits were from the experiment 1 and treatment was the same as the last one, feeding diet with the three nutrition level respectively. After 60 days experiment, effects of different feeding models on growing performance, hair density, diarrhea rate and mortality, nutrition digestion rate and blood index were observed. The experiment results showed that:(1) There were no obvious difference(P>0.05) for the three groups on final weight and daily gain of the young rabbits at the period of 30 to 90 days; but daily feed intake of the groupâ…¡was higher observably(P<0.01), about 10.31% higher than groupâ…¡; feed intake of the groupâ…¡was higher extremely than the other two groups, about 4.58% and 4.89% respectively;(2) The diarrhea rate and mortality of growing rabbits in groupâ…¡were lower, compared with the other two groups;(3) The digestibility of groupâ…¡was lower obviously than groupâ…¡andâ…¡( P <0. 05);(4) Hair density of groupâ…¡was 14.99% higher than groupâ…¡, the difference was obvious(P<0.01),but there was no obvious difference on the hair length(P>0.05);(5) Effects of each text group diet on growing rex rabbit on blood biochemical (total protein, albumin, globulin, cholesterol, serum urea nitrogen, blood glucose, blood calcium, blood phosphorus, glutamic-pyruvic transaminase, aspartate aminotransferase, alkaline phosphatase and immunoglobulin (lgA, lgM, lgG) were compared, there were no obvious difference(P>0.05) .
