Abstract
The productive and reproductive performances of dairy cattle along with the management aspects of the farm have a direct effect on farm profitability. The present study was carried out from a sample of 120 dairy herds using pretested and well-organized semi- structured questionnaire in Bharatpur Metropolitan City, Chitwan. Productive and reproductive performances of two common breeds, Jersey Cross and Holstein Cross were analyzed. The average daily milk yield, lactation length, lactation milk yield, peak yield and dry period for Jersey Cross and Holstein Cross with the Nepalese hill cattle were observed to be 7.39±0.87 and 9.30±0.76 L./day; 303.31±8.12 and 314.18±12.75 days; 2253.39±265.28 and 2936.36±237.55 L.; 12.77±0.92 and 15.11±0.85 L. and 65.26±7.71 and 70.83±10.27 days respectively. The age at first calving (29.08±1.99 and 30.42±1.81 months), Service period (82.37±10.99 and 100.64±13.44 days), Service per conception (1.71±0.54 and 1.82±0.58 times/cow) and Calving interval (365.37±10.92 and 385.56±13.46 days) respectively for Jersey crosses and Holesteinc crosses. The significant relationship (p<0.05) was found between farms having single breeds and double breeds on the productive performances. Likewise, the significant relationship (p<0.05) was also found between farms having single and double breeds on reproductive performances. The significant relationship (p<0.05) was observed between the herd size and age at first calving on jersey cross and none of the parameters showed significant relationship (p>0.05) between the herd size and productive parameters. Further research on needs to be carried out see the particular relationships among production, reproduction and management aspects.
奶牛的生产和繁殖性能以及农场的管理方面对农场的盈利能力有直接影响。本研究是在Chitwan巴拉特普尔市的120头奶牛群中使用预先测试和组织良好的半结构化问卷进行的。分析了泽西杂交和荷斯坦杂交两个常见品种的生产和繁殖性能。泽西杂交和荷斯坦杂交与尼泊尔山地牛的平均日产奶量、泌乳时长、泌乳量、高峰产奶量和干期分别为7.39±0.87 l /d和9.30±0.76 l /d;303.31±8.12天和314.18±12.75天;2253.39±265.28和2936.36±237.55 l;分别为12.77±0.92天和15.11±0.85天和65.26±7.71天和70.83±10.27天。泽西杂交和荷尔斯坦杂交的初产龄(29.08±1.99和30.42±1.81个月)、产仔期(82.37±10.99和100.64±13.44天)、单胎产仔期(1.71±0.54和1.82±0.58次/头)和产犊间隔(365.37±10.92和385.56±13.46天)。单种养殖场与双种养殖场的生产性能呈显著相关(p<0.05)。单、双品种养殖场在繁殖性能上也存在显著相关(p<0.05)。泽西杂交上,猪群规模与初产年龄呈显著相关(p>0.05),各参数与生产参数均无显著相关(p>0.05)。需要进行进一步的研究,看看生产、再生产和管理方面的特殊关系。
