The effect of crossbreeding with Red and White Holstein on milk yield of Romanian Simmental cattle



Zootehnie si Medicina Veterinara 40(7-9): 12-19



For 301 Romanian Simmental (RS) and 106 Red and White Holstein (RWH) X RS cows, lactation milk yield in the first 3 lactations averaged 5082 (4163-5296) and 5633 kg (4676-5982) resp., milk fat percentage 3.92 (3.91-3.93) and 3.92, and milk fat yield 199.6 (162.6-208.4) and 217.4 (183.5-234.5) kg. For 191 and 29 cows with 25 or 37.5% of RWH inheritance resp., lactation milk yield in the first 3 lactations averaged 4311 and 5128 kg at 3.88 and 3.90% fat.
