Pasture Area

Abstract The expression production potential represents the maximum amount of products that can be obtained per unit area. However, what is the maximum amount of product that can be obtained in a pasture area? To answer this question, it is necessary to understand the factors related to forage accumulation, grazing efficiency, chemical composition of the forage plant, forage intake and nutritional requirements of animals, management, genetics, and management of the production system. The average annual productivity of beef cattle in Brazil is approximately 120 kg of body weight (approximately 60 kg of carcass) per hectare. This index is below the parameters reported in the literature. Adequate management of pastures with tropical forages usually provides a stocking rate above one animal unit (450 kg) per hectare. The increase in the stocking rate, combined with high individual body weight gain, provides high productivity, which may exceed 1260 kg of body weight (approximately 630 of carcass) per hectare per year. The production of beef cattle in tropical pastures has a high response potential with regard to the adoption of technologies to increase productivity indices.

High Productivity

Backgrounds: Broiler chickens are high productivity livestock. To achieve this productivity, many farmers provide feed additives. Fermented milk is one of the feed additives given through drinking water. Providing feed additives, regularly, will affect the performance of these broilers. Purpose: To investigate the potential of providing fermented milk through drinking water on the performance of broiler chickens. Method: Direct observations and perform calculations on several aspects that support the research. Result: After making observations, it was known that there are differences in the starter phase and the finisher phase. The observation was carried out from the age of 0-27 days. Broiler performance determined by the parameters of feed consumption, chicken body weight, and feed conversion. Conclusion: The observation shows an increase in feed consumption. However, in feed conversion and body weight gain instability is caused by physical conditions, temperature, and palatability in each phase of the broiler chickens.

Abstract To evaluate the effects of stocking and supplementation rates on steers grazing mixed-grass prairie during winter, 16 pastures (10 to 21 ha each) were selected and treatments were arranged in a 3 x 2 factorial design; the first factor was an stocking rate of 39.4, 33.2, and 29.7 animal-unit-d/ha harvested over 88 d of grazing; the second factor was supplementation at 0.9 or 1.4 kg/d. Steers were fed a 43% CP cottonseed meal-based pellet. Pastures were stocked annually in late January (2009, 2010, and 2011) with British x Continental crossbred beef steers (body weight = 202 ± 6.7 kg; n = 137 steers/yr) at stocking densities described above. Data were analyzed by ANOVA with pasture as the experimental unit and year as a random variable; least-squares means were separated with linear and quadratic contrast. From late-January to mid-March, average daily gain (ADG, kg) did not differ (P = 0.13) among stocking rates, but ADG differed (P = 0.01) between 0.9 and 1.4 kg of supplement/d. From mid-March to late-April and over the entire grazing period, ADG responded to stocking rate and interacted (P < 0.01) with supplementation rate; ADG tended to respond quadratically (P ≤ 0.09) to stocking rate at 0.9 kg/d of supplementation, but with 1.4 kg/d of supplement ADG was not affected (P ≥ 0.18). Body weight gain per hectare tended (P < 0.08) to interact between stocking and supplementation rates. With 0.9 kg/d of supplement the BW gain per hectare increased quadratically (P < 0.01) in response to increasing stocking rate, where supplementation at 1.4 kg/d resulted in BW gain per hectare increasing linearly (P < 0.01). Optimal supplementation rates with high-protein feeds is related to stocking rate. At lower stocking rates, less supplement seems to be most beneficial. At higher stocking rates, more supplement is justified.

1. Antlers were removed in September from 2-4-year-old red deer (Cervus elaphus L.). Both well-fed penned stags and less. well-nourished grazing stags were studied.2. For deer of the same age, both log antler weight and log antler specific gravity were related to body-weight in September and to body-weight gain between March and September. The antlers of 3- and 4-year-old stags were heavier and tended to be denser relative to body-weight and body-weight gain than those of 2-year-old stags.3. For grazing stags of a given age, antler weight and specific gravity, and body-weight and body-weight gain, were progressively less in the three successive years of the study. This appeared to reflect increasing stocking rate over this period.4. The composition of the antlers did not vary significantly between penned and grazing stags or with age. However the concentrations of ash, phosphorus and magnesium in dry matter showed significant positive correlations with specific gravity, that of zinc a significant negative correlation, while calcium, copper and manganese showed no significant correlation.5. The antlers evidently provide a useful index of the changes in body-weight of the stags.

Previously, we have found that the addition of L-ascorbic acid to chitosan enhanced the reduction in body weight gain in guinea pigs fed a high-fat diet. We hypothesized that the addition of L-ascorbic acid to chitosan would accelerate the reduction of body weight in humans, similar to the animal model. Overweight subjects administered chitosan with or without L-ascorbic acid for 8 weeks, were assigned to three groups: Control group (N = 26, placebo, vehicle only), Chito group (N = 27, 3 g/day chitosan), and Chito-vita group (N = 27, 3 g/day chitosan plus 2 g/day L-ascorbic acid). The body weights and body mass index (BMI) of the Chito and Chito-vita groups decreased significantly (p < 0.05) compared to the Control group. The BMI of the Chito-vita group decreased significantly compared to the Chito group (Chito: -1.0 kg/m2 vs. Chito-vita: -1.6 kg/m2, p < 0.05). The results showed that the chitosan enhanced reduction of body weight and BMI was accentuated by the addition of L-ascorbic acid. The fat mass, percentage body fat, body circumference, and skinfold thickness in the Chito and Chito-vita groups decreased more than the Control group; however, these parameters were not significantly different between the three groups. Chitosan combined with L-ascorbic acid may be useful for controlling body weight.

The objective of the research was to evaluate to effect of feeding mengkudu on performances of broilers. The research design used was completely randomized design. One hundred broilers were distributed into five treatments. The treatments were different levels of mengkudu meal (0, 0.75%, 1.5%, 2.25 % and 3%). The observed measured were feed consumption, average body weight (gain) and feed conversion. Results showed that feeding mengkudu (Morinda Citrifolia L.)  no effect significant (P>0.05) on feed consumption, average body weight and feed conversion.  In conclusion, feeding mengkudu meal up to 3% (in diet) does not negatively affect feed consumption, average body weight, and feed conversion.

The aim of the study was to determine the development of ramie plants (Boehmeria nivea L. Gaud) and the effect of using ramie leaves on feed on the body weight gain of Wonosobo Sheep (Dombos). Research on the development of ramie plants using survey methods in the area of ramie plant development in Wonosobo Regency. While the research on the use of ramie leaves for fattening was carried out in Butuh Village, Kalikajar District, Wonosobo Regency in 2018. 21 male Dombos were divided into 3 feed treatments with forage proportions of 70%, 50% and 30 ramie leaves respectively. %. The results showed that currently ramie plants were being developed in Wonosobo Regency by CV. Ramindo Berkah Persada Sejahtera in Gandok Village, Kalikajar District, Wonosobo Regency, Central Java. Until now the area of the crop has reached 13 ha. Of this area will produce ramie leaves 195,000 kg / year. If one sheep needs 4 kg of ramie / tail / day leaves, then the potential capacity of sheep is 135 heads / year, if the given one is 50% then the Jurnal Litbang Provinsi Jawa Tengah, Volume 16 202 Nomor 2 – Desember 2018potential capacity is 270 heads / year and if it is reduced again to 25% of ramie leaves then the potential capacity 440 heads / year. The use of ramie leaves as a feed for Wonosobo Sheep fattening can be given as much as 30% in fresh form.
