Abstract

The present study was carried out between October 2014 and September 2015 to characterize and evaluate 297 different cattle and buffalo dairy production systems which represents the most distributed diary systems in Egypt. The Systems included Commercial Systems (CS), Government commercial Systems (GS), Government Research Systems (GR), Traditional Landless system (TLL), Traditional mixed system (TMS) and Traditional intensive Systems (TIS). Results showed that animal breeds had highly significant effect (P<0.001) on all productive traits. Least squares means ± SD of total milk yield were 10613± 2692 kg , 2715± 1697kg, 1844± 86kg, 1629± 637kg, 1661± 714kg and 2603 ± 733kg for (CS), (GS), (GR), (TLL), (TMS) and (TIS), respectively. However, 4% fat corrected milk yield (FCM) reached the value of 10136.32± 2571.29, 2470.82 ± 1544.36, 2813.09 ± 862.32, 2858.44± 1196.06, 2712.45 ± 1270.82 and 2901.17± 853.08 kg for (CS), (GS), (GR), (TLL), (TMS) and (TIS), respectively. Least squares means ± SD for average daily milk yield per head were 27.78 ± 5.53, 9.41 ± 3.74, 6.81 ± 2.02, 7.37 ± 2.68, 6.22 ± 2.49 kg and 11.30 ± 2.56 kg for (CS), (GS), (GR), (TLL), (TMS) and (TIS) respectively. The average of daily fat corrected milk per head were 26.14 ± 5.13, 8.55 ± 3.24, 10.37 ± 3.02, 10.31 ± 4.14, 10.79 ± 3.95 and 12.24 ± 4.25 kg for the same systems, respectively. This associated with lactation length (LL) of 387.77 ± 98.39, 289.50 ± 140.76, 271.04 ± 92.21, 222.59 ± 36.22, 266.15 ± 30.96 and 230.12 ± 28.96 days,

埃及不同乳制品生产系统的比较研究

本研究于2014年10月至2015年9月期间进行，以表征和评估297种不同的牛和水牛乳制品生产系统，这些系统代表了埃及分布最广的乳制品系统。这些系统包括商业系统、政府商业系统、政府研究系统、传统无地系统、传统混合系统和传统集约系统。结果表明，动物品种对各生产性状均有极显著影响(P<0.001)。总产奶量(CS)、(GS)、(GR)、(TLL)、(TMS)和(TIS)的最小二乘均值±SD分别为10613±2692 kg、2715±1697kg、1844±86kg、1629±637kg、1661±714kg和2603±733kg。而(CS)、(GS)、(GR)、(TLL)、(TMS)和(TIS)的4%脂肪校正产奶量(FCM)分别为10136.32±2571.29、2470.82±1544.36、2813.09±862.32、2858.44±1196.06、2712.45±1270.82和2901.17±853.08 kg。平均日产奶量(CS)、(GS)、(GR)、(TLL)、(TMS)和(TIS)的最小二乘均值±SD分别为27.78±5.53、9.41±3.74、6.81±2.02、7.37±2.68、6.22±2.49和11.30±2.56 kg。同一体系的平均日乳量分别为26.14±5.13、8.55±3.24、10.37±3.02、10.31±4.14、10.79±3.95和12.24±4.25 kg。与此相关的泌乳时长(LL)分别为387.77±98.39、289.50±140.76、271.04±92.21、222.59±36.22、266.15±30.96和230.12±28.96天;
