摘要

本研究旨在调查季节和泌乳量对喀布尔Bini Hesar奶牛场荷斯坦奶牛产奶量的影响。为此，从1392-1393年（2013-2014年）奶牛场牛群账簿记录中收集数据。考虑到奶牛的产奶阶段，总产奶量在春季最高18454.95±33L，其次是夏季17060.85±34.5L，而在冬季最低16398.45±31.5L，泌乳量分别为12.04±0.7、13.24±0.8和14.10±0.6升/天。泌乳1～3日，奶牛个体产奶量逐渐增加。第3次泌乳时产奶量最高，第1次泌乳时最低。研究发现，季节和泌乳次数对产奶量有显著影响。

Effect of Season and Lactation Number on Milk Production of Holstein Friesian Cows in Kabul Bini-Hesar Dairy Farm

The present study was designed to investigate the effects of season and lactation number on milk yields in Holstein dairy cows at Kabul Bini Hesar Dairy Farm. For this purpose, data were collected from the dairy farm herd book records during 1392-1393 (2013-2014). Considering the milk yield stages of the cows, the total milk production was highest during the spring season 18,454.95 ± 33 L followed by summer 17,060.85 ± 34.5 L while the lowest milk production obtained in winter 16,398.45 ± 31.5 L. Moreover, the average daily milk production of the cows was significantly different (p 0.05) between the 1st, 2nd and 3rd lactations and the amounts were 12.04 ± 0.7, 13.24 ± 0.8 and 14.10 ± 0.6 L/day respectively. Milk yields of individual cows were gradually increased from 1st to 3rd lactation. The highest milk yield was recorded in 3rd lactation and the lowest was in 1st. From this study it was found that season and lactation number had a significant effect on the milk quantity.
