Influence of Different Origins on Productive Abilities of the First Calving Simmental Cows

Abstract

The basic scientific goal of this investigation was to make a complex view and study of milking traits of two Simmental cow groups in the production conditions of Southern Serbia. A total of 498 Simmental first calving cows and mother cows were investigated. The first calving cows originally arrived from Germany and a comparison of productive abilities between mother cows and their daughters has been performed. Average duration of all lactations investigated was 349.72 days in generation of daughters and 342.31 days in the generation of mothers. Milk production per standard lactation of the cows grown up in our conditions averaged 4127.87 kg with 3.66% or 151,26 kg of milk fat, and in the group of imported cows these values were 3321.14 kg, 3.80% and 142,82 kg respectively. Differences were statistically high significant in all parameters under investigation. The obtained results disclose the problem of acclimatizing of heads from the mother generation and confirm that import of more expensive animals with better genetic potential is economically justified for the breeder only when he is able to provide the best breeding practice and quality voluminous fodder.
