Maintenance Requirements

Improving the productivity and profitability of smallholder cattle enterprises in Indonesia requires greater and more efficient utilisation of underutilised feed resources such as rice straw. The experiment tested the hypothesis that an Ongole cow with low energy requirements can maintain weight (W) on a rice straw-based diet with the addition of a small amount of tree legumes. Thirty-two Ongole cross (Bos indicus) cows were allocated to one of four treatments in a randomised block design with eight cows per treatment. Cows were offered untreated rice straw ad libitum with four levels of tree legumes (0, 11, 21, and 42 g DM/kg W0.75.day) for 20 weeks. Feed intake was determined daily and liveweight was measured every second week. There was no difference in total feed intake between the treatment groups (P > 0.05). Intake of tree legumes was higher when more was offered (P < 0.05), but cows did not consume all of the legumes offered to them. The inclusion of tree legumes in the diet had no effect on organic matter digestibility, ME content of the diet, liveweight gain or estimated energy balance of the cows (P > 0.05). Rice straw alone contained insufficient ME and rumen-degradable N to meet the maintenance requirements of the cows. From the regression relating liveweight change and ME intake for all cows across all diets, the inclusion of tree legumes in the diet at ~12 g DM/kg W0.75.day or 2.8 g DM/kg W.day was enough to meet the energy requirements for maintenance of Ongole cows fed rice straw ad libitum.

Xylanase Enzyme

SUMMARYThe present study aimed to investigate the effects of adding xylanase enzyme (XY) to a basal diet containing 300 g maize stover and 700 g concentrate/kg dry matter (DM) on feed intake, ruminal fermentation, total tract and ruminal digestibility, as well as some blood parameters. Four male Rambouillet sheep (39 ± 1·8 kg body weight), with permanent rumen and duodenum cannulae were used in a 4 × 4 Latin square design. Sheep were fed a basal diet without xylanase addition (control, XY0), or with the addition of xylanase at 1 (XY1), 3 (XY3) or 6 (XY6) μl/g of diet DM for 84 days, with four 21-day experimental periods. Feed intake, digestibility and rumen fermentation parameters were determined on days 16–21 in each experimental period, and the apparent ruminal neutral detergent fibre (NDF) digestibility was determined on days 16 and 17. Treatments XY1 and XY3 increased feed intake, whereas digestibility was increased with XY6. Ruminal NDF digestibility increased when sheep were fed diets treated with xylanase. Ruminal pH, ammonia-N and acetic acid increased with xylanase treated diets. Propionic acid concentration increased with diet XY1 at 3 h post-feeding, but after 9 h post-feeding its concentration decreased in the rumen of sheep fed xylanase treated diets. Xylanase had no effect on blood urea, phosphorus and triglycerides. Addition of xylanase at 6 µl/g DM in a diet containing 300 g maize stover and 700 g concentrate/kg DM and fed to Rambouillet sheep improved feed digestibility and ruminal fermentation without affecting blood parameters.

Present Trial

Introduction:The present trial was designed to investigate the effect of urea or urea molasses treatment of maize stover (MS) on feed intake, nutrient digestibility and profitability of sheep. Twenty yearling male lambs of Hararghe Highland breed at the initial body weight of 15.4 ± 0.57 (mean ± SD) kg.Experiment:The experimental animals were sorted into five blocks based on the initial weight and assigned randomly to four treatments; namely, untreated maize stover ad libitum (T1); urea treated maize stover (UTMS) ad libitum (T2); urea-molasses treated maize stover (UMTMS) ad libitum (T3); all of which were supplemented with 300g concentrate mix of wheat bran (WB) and noug seed cake (NSC) at the ratio of 2:1 and only urea-molasses treated maize stover ad libitum (T4). Feeding trial was carried out for ninety days and digestibility trial for seven days following 3 days of adaptation to the metabolic cage and carrying the fecal collection bag.Results:The result depicted that the content of crude protein (CP) is 5.9, 8, 10, 30.1, and 17.2%, for MS, UTMS, UMTMS, NSC and WB respectively. Total DM intake was higher for T2 (700.7 g/day) and T3 (770.9 g/day) than sheep fed T1 (538.28 g/day) and T4 (481.4 g/day). Apparent DM and CP digestibility were higher for T2 and T3 than T1 and T4. Hence, urea or urea-molasses treated maize stover with concentrate supplement had a good impact on feed intake and digestibility. Conversely, urea-molasses treated maize stover alone failed to improve the feeding value of MS. Therefore, MS treatment with urea and urea-molasses with energy and protein source of supplement has a desirable alternative in enhancing the utilization of maize stover.
