| description | The effect of environment on the reproductive performance of 50 Holstein cows at the Iwo Road Dairy Farm of Oyo State, Nigeria, was evaluated by summarising and analysing data collected on the cows over a seven year period (January 1970 to December 1976).Two main seasons were discernible from the rainfall and temperature data:
(i) the dry season with a mean rainfall of 36mm and mean maximum and minimum temperatures of 31.6oC and 22.3oC respective1y;and
(ii) the wet season with a mean rainfall of 176 mm and mean maximum and minimum temperatures of 29.s0c and 22.7% respectively.
These seasonal variations adversely affected reproductive performance. Data collected for the dry and wet seasons respectively were: services per conception, 3.7.and 2.5; number of conceptions, 35 and 121; first oestrus after calving, 61 and 50;days from first service to conception, 64 and 52; and number of claves born, 53 and 91. |
