ABSTRACT

Study was conducted on Holstein Friesian (HF) × Sahiwal crossbred cows and heifers during 1998–1999. Crossbred cows and heifers were categorized into two groups viz., ‘Frieswal’ (5/8 HF inheritance) and ‘other crosses’ (having other than 5/8 HF inheritance). The overall herd fertility of cows and heifers was 34.01±1.11 and 34.80±1.22 per cent, respectively. Seasons significantly (P0.05) influenced the herd fertility of both cows and heifers. Herd fertility of ‘Frieswal’ cows and heifers ranged from 33.26±6.39 to 39.25±1.51 and 32.46±1.45 to 37.72±2.76 percent, respectively in various seasons. The corresponding values in ‘other crosses’ were 30.80±1.48 to 45.08±2.17 and 29.58±3.65 to 39.41±1.39, respectively. Both in Frieswal and other crosses cows herd frtility per cent was the highest during summer and lowest during winter seasons
