Abstract

Considering the challenging market conditions for dairy farms, calf gender management should be one of the tools used to increase profitability. The objective of this paper was to examine the effect of calf gender on lactation milk traits in Holstein and Simmental cows. Holstein cows that calved a female calf had a higher milk yield (p<0.0001) and lower milk fat and protein content (p<0.01) in the first lactation. The favourable effect of female calf on milk yield was also found in the second lactation of Holstein cows (p<0.0001). Simmental cows that calved female calves in the first and the second lactation also had higher milk yield and lactation gain, however the differences were not significant. Although no statistically significant effect of calf gender on milk yield was determined in the Simmental population, indications of positive effect of female calf gender on lactation milk yield impose the need for further research. Using gender selected semen as a tool for calf gender management could enable to increase the milk yield of Holstein cows and the profitability of Holstein farms as well.

犊牛性别对荷斯坦奶牛和西门塔尔奶牛泌乳性状和泌乳增重的影响

考虑到奶牛场具有挑战性的市场条件，小牛性别管理应该是提高盈利能力的工具之一。本文的目的是研究小牛性别对荷斯坦奶牛和西门塔尔奶牛泌乳性状的影响。产下母牛犊的荷斯坦奶牛在第一次泌乳时产奶量较高（p＜0.0001），乳脂和蛋白质含量较低（p＜0.01）。荷斯坦奶牛在第二次泌乳中也发现了母牛犊对产奶量的有利影响（p＜0.0001）。在第一次和第二次哺乳中产下母牛犊的西门塔尔奶牛也有较高的产奶量和泌乳增重，但差异不显著。尽管在西门塔尔群体中没有确定小牛性别对产奶量的统计学显著影响，但雌性小牛性别对泌乳产奶量有积极影响的迹象表明，需要进一步研究。使用性别选择精液作为小牛性别管理的工具，可以提高荷斯坦奶牛的产奶量和荷斯坦农场的盈利能力。

期刊介绍： Mljekarstvo is an open access, peer-reviewed international quarterly scientific journal. The first issue was published in 1951, by the Croatian Dairy Operators'' Association (today: Croatian Dairy Union, publisher). In a paper at a Union conference held 28 October 1951 in Zagreb it was said: "Our desire is that this magazine does not meet the fate of its predecessors, but that it continues to reflect the creative efforts and to provide guidelines for the producers as well as all other operators employed in the dairy industry." It is our pleasure today to say that wishes of the enthusiasts who attended the conference have come true, and the magazine Mljekarstvo during the last six decades was a reflection of the creative efforts of numerous dairy scientists and experts, and through its texts it served as a guideline in improving production and processing of milk and dairy products. Mljekarstvo has been following all the achievements of the dairy profession in Croatia, and it also gives the short surveys of world achievements. The result of the research of local and foreign scientists and experts always find their place in the magazine Mljekarstvo. It has been edited by our outstanding dairy experts employed at colleges, research institutions and dairy companies.
