Feeding Behaviour of Sahiwal and Friesian Cattle Under a Zero Grazing System in a Tropical Climate

Abstract

A study was conducted in a tropical environment in Kenya, to determine the feeding behaviour of Friesian and Sahiwal cattle fed on napier grass (Penni.setum purpureum) under zero grazing conditions. Measurements were taken from 16 Sahiwal and 16 Friesian heifers over a period of 3 months. on feed and water intake. diet selection and time of feeding. 1\ synopsis of the results indicated that the Sahiwal is a highly selective feeder compared to Friesian. Feed intake was significantly higher for the Sahiwal cattle. Water consumption of the Sahiwal was estimated to be two-thirds that of the Friesian. TIle time spent eating by the Sahiwal was not significantly affected by high day temperatures. unlike the Friesian. which would rest at that time. TIle Sahiwal tended to rest during the night when temperatures were relatively low, while the Friesians appeared not to be affected during such times. These results. therefore, suggest that under warm tropical conditions. feed intake. water consumption and feeding habits of the Sahiwal and Friesiao cattle are different. Further investigations need to be carried out to verify whether these differences occur throughout the year. and under other production systems.
