| مستخلص: | 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. Istražen je utjecaj spola teleta na svojstva mliječnosti holštajn i simentalskih krava. Utvrđeno je da su holštajn krave koje su otelile žensku telad u prvoj laktaciji imale veću mliječnost (p<0,0001), te manji udio mliječne masti i mliječnih proteina (p<0,01). Utvrđen je povoljan utjecaj ženskog spola teleta na mliječnost holštajn krave u drugoj laktaciji (p<0,0001). Simentalske krave koje su prvu i drugu laktaciju započele nakon oteljenja ženske teladi također su imale veću mliječnost i laktacijsku dobit, no utvrđene razlike nisu statistički značajne. Upravljanjem spolom teladi uporabom seksiranog sjemena moguće je povećati mliječnost holštajn krava i dohodovnost holštajn mliječnih farmi. Premda u simentalskoj populaciji nije uočen značajan utjecaj spola teleta na svojstva mliječnosti, zapažene indicije pozitivnog utjecaja ženskog spola na mliječnost nameću potrebu daljnjih istraživanja. U vremenu otežanog poslovanja mliječnih farmi, upravljanje spolom teladi treba biti jedan od alata za postizanje povoljnije razine profitabilnosti. |
