Abstract

This study was performed to determine the growth of Java bulls fed rice straw and concentrates at different levels of protein. Twelve heads of Java bulls, one and a half years old, with initial body weight ranging from 113.83-191 kg were used in this experiment. They were grouped into four replications based on the initial body weight. The rice straw (30%) and concentrates (70%) diet containing three different levels of protein (8.27; 11.03 and 14.43%) were fed during nine weeks. Data gathered were the average daily gain and the average body measurements (chest girth, shoulder height and body length). Result of this study showed that the increase of protein levels from 8.27 to 14,43% did not significantly influence the average daily gain, shoulder height, and body length of Java bulls (P > 0.05), but it influenced daily chest girth (P < 0.05). The average daily gain (ADG), shoulder height and body length were 0.633 kg, 0.08 cm, and 0.09 cm, respectively. The highest average of daily chest girth of Java bulls was T2 = 0.19 cm, followed by T3 = 0.15 cm, and T1 = 0.12 cm. It is concluded that the increase levels of protein from 8.27 to 14.43% did not affect the average daily gain, shoulder height and body length of Java cattle. However, the highest chest girth was achieved by Java cattle which fed concentrate containing 11.03% of protein. Key Words: Growth, Java Bull, Rice Straw, Concentrate, Levels of Protein

Abstract

This study was set up to evaluate the performance of Java and Ongole Crossbred (OC) bulls fedconcentrate and rice straw. A total of four Java bulls and four OC bulls were used in this experiment. Thebulls were fed concentrates (50% of the total dry matter feed requirement) and rice straw (ad libitum).The concentrates were consisted of rice bran, beer waste product, copra meal, minerals, with crudeprotein (CP) and total digestible nutrients (TDN) contents of 15.32% and 73.09%, respectively. Theaverage daily gain (ADG), dry matter intake (DMI), protein and energy intake, and feed conversion ratio(FCR) were observed. The results of this study showed that the ADG, DMI, CP and TDN intake, andFCR were not significantly different (p> 0.05). The ADG of Java and OC bulls were 0.58 kg and 0.78kg, respectively. The averages of DMI, CP and TDN intake were 6.59 kg (2.09% of BW), 0.81 kg and4.34 kg for Java bulls whereas for OC bulls were 6.42 kg (2.11% of BW), 0.78 kg, and 4.20 kg,respectively. The FCR of Java bulls was 11.49 and those of OC bulls was 9.21. It can be concluded thatJava and OC bulls raised intensively and fed concentrate and rice straw had the similar performance.
