ABSTRACT Rice straw and bran are low in protein. This study examined protein supplement (SPN) composed of CASREA (cassava-urea complex) and SOYXYL (protected-protein soybean meal) in rice straw and bran based ration offered to beef cattle. Experiment 1: Casrea1 (no extruded 32% urea and 58% cassava), Casrea2 (extruded 22% urea and 68% cassava), Casrea3 (extruded 27% urea and 63% cassava), and Casrea4 (extruded 32% urea and 58% cassava) were incubated in ruminal fluid. Experiment 2: Protected-protein soybean meal with xylose from Black Liquor’s (BL) of 0, 3, 6, or 9% and extruded at 120, 150, or 180oC, were incubated in ruminal fluid. Experiment 3: The best treatments of experiments 1 and 2 were used as SPN. Sixteen dairy cattle bulls aged 12-15 months were divided into 4 blocks to receive one of the following treatments: R0= rice straw and bran, R1= R0 with SPN A, R2= R0 with SPN B, R3= R0 with SPN C. SPN A, B and C composed of CASREA:SOYXYL in ratio of 20:80, 50:50, and 80:20, respectively. Casrea 2 had the highest microbial protein and post rumen protein digestibility of 29.04 mg and 76.16%, respectively. Protected-protein soybean meal with xylose from BL 3% and extruded at 150oC had the highest microbial protein and post rumen protein digestibility. SPN increased dry matter, organic matter and protein intake and their digestibility, ration efficiency, and daily gain. The highest daily gain (0.85 kg.d-1), ration efficiency (11%), and income over feed cost (Rp 7500 head-1.d-1) were R3. R3 had lower methane energy compare to R0. The result indicated that JDP supplemented with SPN (80% CASREA and 20% SOYXYL) improved ration efficiency and performance of cattle.

    ABSTRACT: Three male Kedah-Kelantan (KK) cattle each ®tted with a ruminal and a T-shaped duodenal cannulae, with an initial body weight of 178:3 AE 5:78 kg were used to study the recovery rate of urinary purine derivatives (PD) after duodenal infusion of incremental amounts of purine bases (PB). During the experiment, the cattle were fed at a maintenance energy level with a diet containing 40% oil palm frond and 60% concentrates. Basal purine ¯ows into the duodenum from the maintenance diet were estimated. Purine bases in the form of adenosine (46%) and guanosine (54%) were infused into the duodenum in four incremental rates equivalent to 10, 15, 30 and 45 mmol purine per day. Urinary allantoin, the principal PD was linearly correlated with PB input, while the contributions of other PD were not affected by treatments. The relationship between daily urinary PD (allantoin, uric acid, hypoxanthine and xanthine) excretion (mmol per day) and duodenal PB ¯ow (mmol per day) was Y ˆ 0:847X ‡ 7:146 (r 2 ˆ 0:50, P < 0:001), suggesting that 0.85 of the supplied exogenous PB were excreted in urine, with an endogenous excretion of 7.15 mmol per day. Urinary PD excretion rates of zebu cattle are similar to those of European cattle. # 2001 Elsevier Science B.V. All rights reserved.

    ABSTRACT: Thirty-eight young Alpine goats, 16.1 (±0.370)kg body weight (BW), were reared at Querétaro, Mexico, grazing on a semi-arid woody brush (Caducifolio espinoso) range land. The experimental goats (n=20) were pastured daily and supplemented with 200g/day of a complex catalytic feed (CCF). It consisted of molasses (14–18%), urea (8–10%), salt (3–4%), limestone (3–4%), cottonseed meal (13–18%), rice polishing (10–13%), corn (11–12%), poultry litter (9–10%), commercial mineral salt (1.3%), ammonium sulfate (0.3–0.5%), cement kiln dust (1.5%), and animal lard (10–15%). The control goats (n=18) were supplemented daily with 300g of a balanced concentrate (BC), containing 1.5% commercial mineral salt, 60% corn, 32.5% wheat bran, and 4% soybean oil meal. Stocking rates varied from 1.45 to 1.85AU/ha and daily stocking rate from 36.4 to 58.6AU/ha. At all times, fibrous forages were available exceeding the voluntary dry matter intake. One fistulated goat was kept in each group. Growth of the experimental goats averaged 95g/day (±3) compared to 76g/day (±5) of the controls (P
