The ultimate pH of the longissimus muscle was measured in 1536 lambs routinely slaughtered at a meat export works in the southern part of the North Island during the 1981/82 season. The mean ultimate pH of ail samples was 5.60, and 7.2 percent of the carcases had values equal to, or above, 6.00 whereas 85.3 percent of carcases had values below 5.80 which is considered to be optimal. The ultimate pH values of samples from lambs slaughtered during the summer period was significantly higher than those obtained during three other seasonal sampling periods and Perendale lambs had significantly higher ultimate pH values as compared to Iambs of other breeds. There was no statistical association between distance travelled before slaughter and the ultimate pH of carcases but there was a highly significant direct correlation between holding periods of lambs in the stockyards and ultimate pH of their meat. There was also a highly significant inverse correlation between fleece weight and ultimate pH and it is suggested that both this effect and the seasonal pattern of ultimate pH values indirectly reflect the major role that nutrition may play in the development of high ultimate pH meat in lambs. It is further suggested that washing of animals prior to slaughter and the length of subsequent resting periods are important factors in relation to the development of undesirably high ultimate pH values.  相似文献

今年我区牛品改的阶段成果和下半年工作意见   总被引:1,自引:0,他引:1  
广西今年牛品改的任务创历史新高。杂交配种的母牛头数 :2 0 0 1年为 8万头 ,2 0 0 2年为2 0 1万头 ,今年定为 50万头。开展杂交的地方增至 76个县 (市 ) ,任重而道远。为完成这个任务 ,计划增建 80 0个配种点 ,培训技术人员 1 50 0人。 1 -4月份已培训配种员 961人 ,新建了 43 2个配种点 ,全区已杂交配种母牛 7 8万头 ,占全年任务的 1 5 56%。来宾市兴宾区报道 ,1 -3月份已配母牛 973 6头 ,占全年任务的 2 2 % ,灵山县畜牧站配种点报道 ,1 -5月份已杂交母牛 1 50 0头 ,初步检查受胎率 65%~ 70 % ,看来大量工作还留待下半年完成。自治区畜…  相似文献
