The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched.

Abstract

Four, rumen fistulated crossbred (Brahman x native) beef cattle steers were randomly assigned to receive four dietary treatments according to a 2 x 2 factorial arrangement in a 4 x 4 Latin square design. Factor A was carbohydrate source; cassava chip (CC) or CC + rice bran at a ratio 3:1 (CR3:1) and Factor B was cotton seed meal level (CM); and 109 g CP/kg (LCM) and 328 g CP/kg (HCM) at similar overall CP levels (490 g CP/kg). The animals were fed 5 g concentrate/kg BW, and urea-treated rice straw (UTS) (50 g urea/kg DM) was fed ad libitum. Carbohydrate source did not affect feed intake, nutrient digestibility, blood urea nitrogen, rumen fermentation, or microbial protein synthesis; however, animals fed with CC had a higher population of total viable bacteria than the CR3:1 treatment (P < 0.05). Animals that received HCM had a lower total feed intake while ruminal pH was higher than the LCM fed treatment (P < 0.05). The population of total viable and cellulolytic bacteria in animals that received HCM were lower than the LCM fed treatment (P < 0.05). Moreover, use of HCM in beef cattle diets resulted in lower microbial protein synthesis when compared with the LCM fed treatment (P < 0.05) although efficiency of microbial protein synthesis was nonsignificantly different among treatments. Therefore, cassava chip combined with rice bran can be used in a concentrate diet for beef cattle. It is also noted that a high level of cotton seed meal in the concentrate may impact rumen fermentation and animal performance.
