Phenotype potential of Busha in milk production

Autochthonous breed in Croatia became marginalized during the second half of the twentieth century due to their small production. Nowadays, genetic characteristics, good adaptability, traditional and other values of these breeds comes to the fore and becoming more challenging for breeders, especially in the organic production system. Sustainability of the breed is in close relationship with its economic affirmation. Busha is more suitable for milk rather than meat production due to her small body frame, therefore new information about milk yield and milk characteristics must be backbone for the future production expectations. The aim of this research was to estimate Busha’s production potential, more precisely milk yield and its chemical composition. Average daily milk production was 7.06 kg/day while during the second month of lactation daily milk production was 9.01 kg. In the second month of lactation daily milk production ranged from 6.45 to 11.91 kg. Estimated average milk production in standard lactation was 2154 kg while lactation potential of cows ranged from 1520 of 2805 kg/305 days. The average fat content was 4.15% and the average content of milk protein was 3.45%. The effect of the lactation stage on the content of fat, protein, lactose, and ash in milk of Busha was not observed. The lactation persistence from third to tenth month was 93.1%. The observed indicators of milk production and chemical composition of the milk are consistent with previous observations. Busha has good potential for milk production, especially in organic, traditional or extensive production.
