摘要: 对安徽白山羊的体性状和肉用性能进行了测定。公羊4,6,8,12月龄的平均体高分别为42.10,46.35,47.66和55.65cm;母羊4,6,8月龄和成年的平均体高分别为40.08,43.76,45.90和63.30cm:羯羊48.30cm。公羊4,6,8,12月龄的平均体长分别为44.24,49.22,50.75和65.00cm;母羊4,6,8月龄和成年的平均体长分别为41.91,46.28,50.06和67.2cm:羯羊45.70cm。公羊4,6,8,12月龄的平均胸围分别为50.08,52.98,56.04和65.00cm;母羊4,6,8,12月龄的平均胸围分别为45.74,49.5,53.33和74.00cm;羯羊50.00cm。公羊4,6,8,12月龄的平均管围分别为6.48,6.78,6.85和7.20cm:母羊4,6,8月龄和成年时的平均管围分别为6.10,6.36,6.61cm和7.80cm;羯羊6.78cm;公羊4,6,8,12月龄的平均宰前体重分别为9.36,12.51,14.59和18.10kg;母羊4,6,8月龄、成年的平均宰前体重分别为7.73,9.67,12.40和26.50kg;羯羊11-45kg;12月龄公羊、成年母羊、羯羊的平均空体重分别为16.66,23.78,10.09kg。平均屠宰率(依宰前活重)12月龄公羊、成年母羊、羯羊的平均屠宰率(依宰前活重)分别为51.11%、49.06%、48.13%。12月龄公羊、成年母羊、羯羊的平均屠宰率(依空活重)分剐为54.50%、54.67%、54.49%。12月龄公羊、成年母羊、羯羊的平均净肉率分剐为34.31%、35.64%、33.50%。12月龄公羊、成年母羊、羯羊的平均肉骨比分别为1:2.10、1:2.70、1:2.85。12月龄公羊、成年母羊、羯羊的平均眼肌面积分别为8.40.8.05,2.96cm^2。

Abstract: Body properties and meat performances of Anhui white goat were determined. The average height of rams at 4, 6, 8 and 12 months old were 4:2.10, 46.35, 47.66 and 55.65 cm, resp., that of ewes at 4, 6, 8 months old and adult ewes were 40.08, 43.76, 45.90 and 63.30 cm, resp., and that of wethers were 48.30 cm. The average body length of rams at 4, 6, 8 and 12 months old were 44.24, 49.22, 50.75 and 65.00 em, resp., that at ewes of 4, 6, 8 months old and adult ewes were 41.91, 46.28, 50.06 and 67.20 cm, resp., and that of wethers were 45.70 cm. The average chest circumference of rams at 4, 6, 8, 12 months old were 50.08, 52.98, 56.04, 65.00 cm, resp, that of ewes at 4, 6, 8, 12 months old were 45.74, 49.50, 53.33 and 74.00 cm, resp., and that of wethers were 50.00 cm. The average cannon circumference of rams at 4, 6, 8 and 12 months old were 6.48, 6.78, 6.85 and 7.20 cm, that of ewes at 4, 6, 8 and 12 months old were 6.10,6.36,6.61 and 7.80 cm, resp., and that of wethers were 6.78 cm. The average liveweight before slaughtering of rams at 4, 6, 8, 12 months old were 9.36, 12.51, 14.59 and 18.10 kg, resp., that of ewes at 4, 6, 8 months old and adult ewes were 7.73, 9.67, 12.40 and 26.50 kg, resp., and that of wethers were 11.45 kg. The average empty body weight of 12-month-old rams, adult ewes and wethers were 16.66, 23.78, 10.09 kg, resp. The average dressing percentage of 12-month-old rams, adult ewes and wethers according to the liveweight before slaughtering were 51.11% ,49.06 % ,48.13 %, resp., that of 12-month-old rams, adult ewes and wethers according to the empty body weight were 54.50 % ,54.67 % ,54.49 %, resp. The average meat percentage of 12-month-old rams, adult ewes and wethers were 34.31% ,35.64 % ,33.50 %, resp. The average meat-bone ratio of 12-month-old rams, adult ewes and wethers were 1: 2.10, 1:2.7, 1:2.85, resp..
