Pregnancy rates, determined by per rectum palpation, were analyzed with respect to cow parity (range 1 to >8 calvings) and body condition score (BCS, 1=thin to 9=fat) at pregnancy examination for 3734 beef cattle females on 3 commercial beef operations (8 herds) in 3 Florida counties in 1989 and 1990. The means and standard deviations for the herds were the following: pregnancy rate, 81.3+-39% (range 62.1 to 91.5%); BCS, 4,7+-0.6 (range 4.3 to 4.9); and parity, 3.9+-2.3 (range 2.8 to 4.8). Significant associations were found between pregnancy rate, parity, BCS and herd (P<0.001); and between the variable interactions, parity with BCS, herd with BCS, and herd with parity (P<0.001). Cows with a BCS<4 had a pregnancy rate of 59%; those with a BCS >5 had a pregnancy rate of 90%. Cows having a parity of <4 had a PR of 80%, while cows having a parity >4 had a PR of 85%. The interaction of parity with BCS was significant, resulting in pregnancy rates as follows; parity <4 and BCS was 1%; parity <4 and BCS > 5 was 88%; parity >4 and BCS <4 was 66%; and parity >5 and BCS >5 was 93%. Body condition, parity and the interacxtion of body condition and parity play important roles in the reproductive performance of commercial beef cows in Florida. |
