Abstract
The objective of this study was to evaluate the effects of utilization of cavalcade as concentrate diet substitute on performance, and economic return in growing sheep. Eight male and eight female Santa Ines crossbred sheep with the initial weight of 16.5±2.0 kg. This experiment used randomized Completely Block Design. Four dietary treatments, were 1) ruzi (T1), 2) ruzi plus concentrate at 1% of body weight (BW) (T2), 3) ruzi : cavalcade 50:50 w/w (T3), and 4) ruzi plus cavalcade at 1%BW (T4). The results showed that the sheep fed with concentrate supplementation (1% of BW) had the significantly highest weight gain and average daily gain (ADG) (P<0.01). In addition, the sheep fed with cavalcade supplement (1% of BW) had the significantly highest total dry matter intakes (g/kg BW0.75) (P<0.01). The sheep fed with ruzi : cavalcade 50:50 w/w had the significantly highest total protein intake (P<0.01) but the significantly lowest NDF and ADF intake (P<0.01). The sheep fed with ruzi had the significantly lowest blood urea nitrogen. Regarding the economic return, it was found that the sheep fed with concentrate supplementation (1% of BW) and cavalcade supplementation (1% of BW) had feed cost per body weight gain of 58.13 and 60.77 Baht/sheep, respectively. It was concluded that supplementation of cavalcade 1% of BW in ruzi roughage diets could be an alternative protein source as substitution of concentrate diet for growing Santa Ines crossbred sheep.
