Abstract
This study was conducted to find out how much losses the breeders get when their cattle experience a decline in day open (DO), service per conception (S/C), and calving interval (CI).There were 108 lactating dairy cows from the dairy farm, Wagir District, Malang Regency.The data that has been taken is then processed by analysis using linear regression method.The results of the analysis prove that reproductive management has an effect of 82% on farmer expenditure.For each setback DO per day, the farmer pays Rp. 609,05.Meanwhile, for each additional S/C the farmer pays Rp. 99,921.7.For each setback the farmer CI will incur a fee of IDR 228,54 / day.So that the equation found is expendses = 609,05 (DO) + 99,921.7 (s / c) +228,54 (CI).
本研究旨在了解当奶牛的开放日(DO)、单胎产仔数(S/C)和产犊间隔(CI)下降时，养殖户的损失有多大。来自玛琅县瓦格尔县奶牛场的108头泌乳奶牛。然后使用线性回归方法对所采集的数据进行分析处理。分析结果证明，生殖管理对农民支出的影响达82%。对于每天的每个挫折DO，农民支付609,05卢比。同时，每增加一份S/C，农民要支付99,921.7卢比。对于每一次挫折，农民CI将产生228,54印尼盾/天的费用。因此，得出的方程是:费用= 609,05 (DO) + 99,921.7 (s / c) +228,54 (CI)。
