Morphofunction characteristics of udder of Swiss breed cows

Abstract

The research conducted on Swiss cows imported to Uzbekistan revealed significant differences in udder shape and milk production among different groups. In group I, comprising 6 cows (50%), a pelvic udder shape was predominant, while in group II, 10 cows (83.33%) had a cup-shaped udder. Interestingly, there were no cows with pelvic udders in group III, with 8 cows (66.67%) having cup-shaped udders and 4 cows (33.33%) having round udders. Milk production data showed notable variations between cows with different udder shapes. In group I, cows with pelvic udders produced 449.7 kg of milk during lactation, with a milk fat yield of 22 kg and a milk protein yield of 19.2 kg. Comparatively, cows with pelvic udders in group II produced 513.9 kg of milk with 4% fat yield and a milk fat yield of 98.1 kg. Notably, cows in group I produced 1300.4 kg of milk, which is 40.6% of the standard requirements of the Swiss breed, while cows in group II produced 850.7 kg, equivalent to 26.6% of the standard requirements. These findings suggest a strong correlation between udder shape and milk production efficiency in Swiss cows.
