This study has been carried out in the Western Mediterranean Region of Turkey on seven different Honamli goat flocks. The aim of this study was to determine the growth characters, survival rate (till weaning, 105th day), some reproductive characteristics and marketable milk yield. The data were collected from 516 does and 210 kids (125 buckling and 85 doelings). The results indicate that the numbers of multiple birth and litter size were 32.8 % and 1.35 respectively. Survival rates of kids at the 30th, 90th, and 105th days were 98.5, 97.2, and 97.2 %, respectively. The average birth weight for the buckling and doelings was 4.1 and 3.7 kg, respectively. The average weaning weights for buckling and doelings were 26.9 and 23.4 kg, respectively. The effects of dams' age, on sex and birth type on the growth of Honamli kids were statistically significant (p < 0.05, p < 0.01, and p < 0.001). While the diameters of erythrocytes of Honamli goats are smaller, the density of hemoglobin in the erythrocytes is more than Asian, Indian, and American caprine breeds. The average lactation length and marketable milk yield was assessed to be at 210.3 days and was 89 L, respectively. The growth characteristics of Honamli kids at weaning age were assessed to be higher than most of the other goat breeds in Turkey. The results further indicated that there is a significant variation in the production traits among the different Honamli goat flocks. Production traits of Honamli goats at different breeding conditions should further be investigated to come to a definite conclusion.
本研究在土耳其西地中海地区的七个不同霍纳姆利山羊群中开展。本研究的目的是确定生长特征、存活率(至断奶,第105天)、一些繁殖特征和可销售奶产量。数据收集自516只母羊和210只羔羊(125只公羔和85只母羔)。结果表明,多胎率和产仔数分别为32.8%和1.35。羔羊在第30天、第90天和第105天的存活率分别为98.5%、97.2%和97.2%。公羔和母羔的平均出生体重分别为4.1千克和3.7千克。公羔和母羔的平均断奶体重分别为26.9千克和23.4千克。母羊年龄、性别和出生类型对霍纳姆利羔羊生长的影响具有统计学意义(p<0.05、p<0.01和p<0.001)。霍纳姆利山羊的红细胞直径较小,但其红细胞内血红蛋白密度高于亚洲、印度和美洲的山羊品种。平均泌乳期和可销售奶产量分别评估为210.3天和89升。霍纳姆利羔羊断奶时的生长特征评估高于土耳其的大多数其他山羊品种。结果还表明,不同霍纳姆利山羊群之间的生产性状存在显著差异。应进一步研究不同养殖条件下霍纳姆利山羊的生产性状,以便得出明确结论。
