Behavior of climatic factors and their relation with the reproductive indicators of meat cattle.

Abstract

It was evaluated the influence of climatic factors in the reproductive behavior of the cattle breeding. The major values of temperature (30.5 - 32.5°C) were measured in the rainy season where it was verified a greater concentration of fertile heats (73, 92% total), although in the months of higher temperature the occurrence heats was of 31,12%. The precipitations did not exceed the 123 millimeters, the more rainy years were 2005 and 2006, where less periods of services were obtained (111 and 128 days), and periods between births (391 and 408). It was determined with accuracy the dry season extend from May to September and the rainy season from October to April. The relative humidity tended to increase since 2007 which corresponds with the years of major period of service and birth intervals. It was recommended to establish an exploitation system taking into account these conditions.
