 หัวเรื่อง:ผลการใช้มันเส้นเป็นหลักในสูตรอาหารขุนแกะ ผู้เขียน: Sumon Pojun, Prasert Pojun, Sawakon Rojanastid สื่อสิ่งพิมพ์:pdf Abstract The study was aimed at supplementation levels of concentrate composing of dry cassava chip as basal feed for lambs receiving fresh para-grass ad libitum. Eighteen weaning lambs were divided into 3 groups of 6 animals each ( 4 males, 2 females ). Each group was randomly allocated to supplemented concentrate at 200, 400 and 600 gm/head/day until 30 kg body weight. The result showed that average daily gain and feed conversion ratio of lambs fed with the above diets were 73.13, 111.52,131.15 gm/day and 8.17, 6.68 and 6.42, respectively. Although there was no significant differences in average daily gain, feed conversion ratio, fattening period and carcass quality between group 2 and group 3, lambs received 600 gm concentrate/head/day showed the best daily gain (131.15 gm/day ), feed conversion ratio ( 6. 42 ) and fattening period ( 137 days ). Costs of feeding per 1 kg. liveweight gain were 12.00, 12.34 and 12.89 baht for the respective groups 1, 2 and 3. |
