The aim of this research was to compare different feeding strategies to increase the weight and body condition score (BCS) of Ongole (Bos indicus) and Bali (Bos javanicus) cows kept by smallholder farmers in Indonesia. Thirty mature, non-pregnant, non-lactating Ongole and Bali cows were allocated to one of three treatment groups in a randomised block design, with five cows of each breed per treatment. The experiment consisted of a 2-week adaptation period and 24-week experimental period. In Weeks 1–17 cows were offered one of three diets; rice straw ad libitum plus gliricidia (Gliricidia sepium) at 3 g DM/kg W.day (RSG3), rice straw at 10 g DM/kg W.day plus gliricidia at 10 g DM/kg W.day, or elephant grass (Pennisetum purpureum) ad libitum. During Weeks 18–24 the cows previously fed the RSG3 diet were offered rice straw ad libitum plus rice bran at 10 g DM/kg W.day. There was no change to diets of the other groups. Feeding untreated rice straw plus gliricidia or rice bran only provided enough metabolisable energy for maintenance of both breeds. Ongole and Bali cows consuming elephant grass gained weight at 0.25 and 0.33 kg/day, respectively. However, even at these higher growth rates it would still take ~4–6 months for cows to gain 1 BCS unit (1–5 scale). Maintaining a good BCS would be a better management strategy.

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.

This study aimed to evaluate how different irrigation water depths influence the agronomical features of elephant grass (Pennisetum purpureum Schum) cv. Roxo. Grass was cultivated in a pasture belonging to the Bovine Sector of the National Agrotechnical School of Caceres – MT. The experiment was a block design with five treatments and four repetitions. Treatments consisted of five water depths: 0 = 0% of available water (AW), 1 = 21% of AW, 2 = 34% of AW, 3 = 74% of AW, and 5 = 100% of AW. Evaluated features were production (dry matter ha-1), plant height, leaf/steam ratio, and stem diameter. Dry matter production of cuts from May and July increased linearly with increasing water depth (P < 0.05). Plant height increased linearly as water depth increased in the cuts of May and September, while the height of July cuts was 71.76 cm under an irrigation depth of 390.77 mm. In May, July, and September cuts, leaf percentage decreased linearly as water depth increased (P < 0.05). An increase of 1 mm in water depth reduced leaf percentage by 0.0936% (May), 0.0295% (July), and 0.0122% (September). Our results indicate that to improve dry matter production, May, July, and September cuts should be irrigated with water depths of 56.03 mm, 601.78 mm, and 577.65 mm, respectively.

The aim of this experiment was to test the effectiveness of two diets in increasing liveweight (LW) and body condition score (BCS) of Brahman cows in Indonesia. Diets were based on rice straw, with additional energy and nitrogen (N) provided in the form of onggok (a cassava by-product) plus urea or a tree legume. Thirty mature, non-pregnant, non-lactating Brahman crossbred cows (288 kg LW, BCS 2/5) were allocated to one of two treatment groups. Cows were kept in individual pens for 21 weeks and offered one of two diets; (1) urea-supplemented rice straw ad libitum plus 10 g onggok DM/kg LW.day, or (2) untreated rice straw ad libitum plus 5 g onggok DM/kg LW.day and 5 g Gliricidia sepium DM/kg LW.day. The urea supplement provided no advantages over using locally available N sources such as gliricidia, with both supplement types meeting the rumen-degradable N requirements of the cows. Cows on both diets gained weight at a similar rate (0.19 kg/day) for the first 15 weeks of the experiment. Liveweight gain in Weeks 16–21 was only 0.04 kg/day, despite an increase in total feed intake and energy content of the diets compared with Weeks 1–15. Liveweight of cows stabilised during Weeks 16–21 at 304 kg, BCS 2.2. While our results demonstrate that Brahman cows can maintain LW on rice straw-based diets, they may not be able to maintain a BCS sufficient for good reproduction rates (i.e. BCS 3 or higher on 1–5 scale). Better quality diets containing higher levels of energy are required for cows to gain and maintain a suitable BCS.

SUMMARYIndonesian Ongole and swamp buffalo bulls were fed ad libitum a diet of elephant grass (Pennisetum purpureum) with five levels of rice bran (0, 1·2, 2·4, 3·6 and 4·8 kg/head/ day) in a study lasting 161 days. Measurements were made of the digestibility of the diet, the balances of nitrogen, phosphorus, calcium and water and the metabolizability of the gross energy. Using multiple regressions, the daily intakes of metabolizable energy were partitioned between maintenance and growth.Feeding rice bran stimulated appetite, initially improved feed conversion efficiency and increased growth rates. Each additional kilogram of rice bran fed depressed grass dry-matter intake by 0·8 kg in the buffaloes and 0·6 kg in Ongoles. Rice bran had little effect on digestibility of dry matter, organic matter and energy. Metabolizable energy contents of rice bran and elephant grass were calculated to be, respectively, 9·5 and 8·2 MJ/kg dry matter. Nitrogen and phosphorus status was improved in the supplemented animals but the balance of calcium was adversely affected. Voluntary feed intake was always higher in the buffaloes but the differences were reduced with increasing rice-bran supplementation.Metabolizable energy requirements for maintenance and growth did not differ significantly between Ongole and buffaloes and were similar to values calculated for British animals.

Two experiments were conducted with weaned entire male Bali cattle (Bos javanicus) between 6 and 12 months of age. A randomised block design was used in both experiments, which consisted of four treatments (diets), with five replicates (animals) per treatment. In both experiments, the average daily liveweight gain (LWG), feed and water intake and diet digestibility were determined over 8 or 10 weeks, with chest girth and wither height measured at the commencement and end of the experiments. In Experiment 1, the treatments were fresh native grass, native grass supplemented with fresh sesbania, fresh sesbania and fresh sesbania supplemented with rice bran. In Experiment 2, the treatments were sole diets of leucaena hay, sesbania hay, moringa hay or gliricidia hay supplemented with sesbania hay. In Experiment 1, animals fed sesbania supplemented with rice bran had higher DM intake than did animals fed the other three diets. DM digestibility (DMD) was significantly lower for weaners fed the native grass diet than for those fed the other diets. Animals fed sesbania or sesbania supplemented with rice bran had a higher LWG (0.34 and 0.43 kg/day, respectively) and estimated metabolisable energy (ME) intake (0.71 and 0.80 MJ of ME/kg W0.75.day, respectively) than did animals fed native grass alone (0.03 kg/day; 0.58 MJ of ME/kg W0.75.day) or native grass supplemented with sesbania (0.07 kg/day; 0.64 MJ of ME/kg W0.75.day). In Experiment 2, animals fed gliricidia hay had the lowest DM intake. DM intake of animals fed moringa hay was higher than that of animals fed gliricidia hay, but lower than the intake of animals fed sesbania hay or leucaena hay. DMD of the sesbania and leucaena hay diets was lower than that of the gliricidia and moringa hay diets. Animals fed leucaena and sesbania hays had a higher LWG (0.47 and 0.43 kg/day, respectively) and estimated ME intake (0.75 and 0.78 MJ of ME/kg W0.75.day, respectively) than did animals fed moringa hay (0.22 kg/day; 0.66 MJ ME/kg W0.75.day) or gliricidia hay supplemented with sesbania hay (0.0 kg/day; 0.48 MJ ME/kg W0.75.day). In conclusion, tree legumes can safely be fed to growing Bali cattle as the sole component of the diet and some of them will increase LWGs above that of native grasses, which are typically fed to Bali cattle in villages.

Odot elephant grass is a tropical forage forage that is easily developed, has high production and can be used as animal feed.This study aims to determine the effect of ameliorant types and organic fertilizer (Agrodyke) doses on the growth of odot elephant grass (Pennisetum purpureum cv. Mott) on peatlands. This study used a 3x3 factorial randomized block design (RBD) with 3 replications consisting of: (1) ameliorant type factor (A) consisting of 3 levels, namely: A1 =dolomite lime, A2 = Shellfish shell, A3 = Eggshell. (2) Agrodyke fertilizer dose factor (D) Consists of 3 levels, namely: D0 = 0 gram / plant, D1 = 10 gram / plant, D2 = 20 gram / plant. Observation parameters are the number of leaves, number of shoots, leaf length, plant height. The results of this study indicate that the type of ameliorant did not significantly affect the number of leaves, number of shoots, leaf length, and plant height at 2 MST, 4 MST, and 6 MST. Versatile fertilizer (Agrodyke) dosage significantly affected the number of leaves and plant height at 6 MST. But no significant effect on the number of leaves, number of shoots and plant height in 2 MST and 4 MST. Keywords: Peat, Ameliorant Species, Odot Elephant Grass, Agrodyke.

Randomized Block Design

The study aimed to evaluate the agronomic characteristics of elephant grass (Pennisetum purpureum Schum.) genotypes on energy production in the combustion form. A randomized block design with 3 repetitions was used. The treatments were arranged in subdivided plots scheme, considering as a plot the genotypes and as subplots, the harvest season. The agronomic characteristics plant height (H), leaf length (LL), leaf blade width (LBW), stem diameter (SD), tillers number (TN), stem percentage (SP), dry matter yield (DMY) were evaluated. The rainy season provided greater H to elephant grass genotypes with height above 3.5 m. The average SP obtained by the genotypes was 68.21% and 67.21% to the first and second year of cultivation, respectively, which gives the biomass good quality of burning. The rainy season provided greater DMY comparing to the dry season. In the first year of cultivation there were genotypes with annual dry matter yield (ADMY) above 50 ton ha-1 year-1, however, the non-maintenance of soil fertility promoted the reduction of 39.17% and 39.05% in the DMY and ADMY, respectively. Analyzing the agronomic characteristics, we conclude that the promising genotypes of elephant grass to produce energy in the form of direct combustion are CNPGL 91-25-1, Cubano Pinda, BRS Canará, Porto Rico and Mercker.

The purpose of this research was to evaluate the behavior per se of elephant grass (Pennisetum purpureum Shum) hybrids for energy purposes by means of morpho-agronomic traits in four evaluation sections. An experiment in randomized block design with three replicates was applied to evaluate the hybrids. The plot consisted of a 15-m row with 1.50-m row spacing, and 1.50-m spacing between plants. The usable area was composed of the five central plants. It was evaluated Number of tillers per clump; Stem diameter; Plant height; Plant dry matter yield; and Percentage of dry matter. Computational resources from the GENES Program were used to analyze the results. In both cuts, the H7, H11, and H14 hybrids was superior to the others in the four evaluation cuts for all evaluated characteristics, proving to be a potential genotype to be used for energy biomass production.

SUMMARYHerbage accumulation is determined by the tissue turnover of individual plants and by the regulation patterns of the number of individuals in a plant population, which function in conjunction to enable swards to adapt to variations in growth and management conditions. Based on the hypothesis that intermittent grazing strategies change the proportion of basal and aerial tillers and, consequently, sward herbage accumulation, the objective of the current experiment was to evaluate the components of herbage accumulation in elephant grass cvar Napier (Pennisetum purpureum Schum. cvar Napier) from January 2011 to April 2012. The treatments corresponded to combinations of two post-grazing (post-grazing heights of 35 and 45 cm) and two pre-grazing conditions (0·95 and maximum canopy light interception during regrowth – LI0·95 and LIMax) and were allocated to experimental units (850 m2 paddocks) according to a 2×2 factorial arrangement in a complete randomized block design with four replications. The following response variables were evaluated: the population density of basal tillers (TPDb) and the population density of aerial tillers (TPDa), the number of aerial tillers per supporting unit (A/B+VC), growth rates of the leaf (LGR) and stem (SGR), leaf senescence rate, net leaf accumulation rate (LAR), and the contributions of basal and aerial tillers to sward growth and senescence. The swards managed with the LI0·95 target had greater TPDb than those managed with the LIMax target, but no difference was recorded between the LI pre-grazing targets for TPDa. The larger A/B+VC ratio recorded for the swards managed with the LIMax target resulted in a higher contribution of aerial tillers to the growth and senescence of swards. This growth strategy resulted in a higher SGR and lower LGR and LAR for the swards managed with the LIMax target relative to those managed with the LI0·95 target. The post-grazing height targets affected only LGR during winter and the second summer and SGR on average for the experiment, with higher values recorded for the swards managed at 35 cm. The LI pre-grazing targets played a central role in defining the compensatory mechanisms responsible for the competitive ability of the plants, which were primarily expressed in the variation of the proportion of basal and aerial tillers in the tiller population and interfered with the components of herbage accumulation and total herbage yield of the swards.
