Abstract

The current study was conducted to evaluate the effects of different proportions of Coix lacryma-jobi cv. Daheishan meal substituted for alfalfa meal on growth performance, health status, apparent nutrient digestibility and slaughter performance of growing meat rabbits. A total of 150 weaned New Zealand white rabbits, aged 35 days with similar body weight, were assigned to a 28-day feeding experiment and a 11-day digestion experiment. For feeding experiment, one hundred experimental rabbits with the body weight of (1.00±0.09) kg were randomly allocated to 5 groups with 10 replicates per group and 2 rabbits per replicate. For digestion experiment, fifty experimental rabbits with the body weight of (1.12±0.05) kg were allocated to 5 groups with 10 replicates per group and 1 rabbit per replicate. In the digestion experiment, the sampling period was 4 days. Experimental rabbits in the 5 groups of feeding experiment or digestion experiment were fed five isoenergetic, isonitrogenous and isofibrous diets including one control diet (contaning 16% alfalfa meal, group C) and four test diets which used Coix lacryma-jobi cv. Daheishan meal to replace 25% (group S25), 50% (group S50), 75% (group S75) and 100% (group S100) alfalfa meal in the control diet, respectively. The results showed as follows:1) there were no significant differences in average daily feed intake (ADFI), average daily gain (ADG) and feed/gain (F/G) in each period among groups (P>0.05), but the ADG and F/G in group S50 were better. The morbidity, mortality, health risk index in the whole period, and hot carcass weight, commercial carcass weight, reference carcass weight, commercial slaughter rate and drip loss percentage at the end of the test had no significant differences among groups (P>0.05), but the numerical value of most indicators in group S50 were higher than those in group C. 2) Different proportions of Coix lacryma-jobi cv. Daheishan meal substituted for alfalfa meal had significant effects on the apparent digestibility of dry matter, crude protein, ether extract, ash, neutral detergent fiber, calcium and phosphorus (P<0.05 or P<0.01). All nutrient apparent digestibility (except ether extract apparent digestibility lower and crude fibre apparent digestibility similar) in the 4 test groups (groups S25, S50, S75 and S100) were higher than those in group C, especially group S50. According to above results, dietary alfalfa meal of commercial rabbits can be totally replaced by Coix lacryma-jobi cv. Daheishan meal, and 50% is the best replacing proportion in this study.

Key words： Coix lacryma-jobi cv. Daheishan meal; growth performance; nutrient apparent digestibility; slaughter performance; growing meat rabbits
