Abstract

Only limited work has been done to assess the potential of Philippines native goat in terms of conformation and component parts of the carcass. Thus, an experiment has been conducted at Institute of Animal Science, University of the Philippines  os Baños, Philippines to determine carcass and lean-fat-bone yield of different cuts of chevon from Philippine native goat.  Result showed that among the wholesale cuts of chevon, shoulder had significantly higher separable lean content (8.80% of LW) than leg, loin, rib, and neck. Based on % wholesale cuts (WC), however, the leg had significantly higher value (69.18%) than the other chevon cuts. Loin had significantly higher separable fat (1.67% of LW) than the other chevon cuts. Shoulder had significantly higher separable bone (4.62% of LW). Based on %WC, however, rib had significantly higher separable bone (53.36%) than the other cuts. The shoulder had significantly higher boneless recovery (9.39% of LW) than other chevon cuts.     Key Words: Chevon, Carcass, Live Weight, Wholesale Cut

Abstract

The aim of this research was held in Institute of Animal Science farm, University of the Philippines Los Banos, was to know the effects of acid protease supplementation in layer diets. Ninety-four-week old pullets were caged individually. Five treatments were randomly arranged to 95 pullets following a completely randomized design. Each treatment was replicated 19 times. The feeding trial lasted for 16 weeks. The same management practices were provided to all treatments throughout the feeding period. Pullets were fed once a day in the morning and clean drinking water was available to the pullets at all times. A basal layer diet that contained 18% crude protein (CP) and 2800 Kcal ME/kg supplemented with required vitamins, minerals and amino acids were formulated. The diets with reduced protein of 17% and 2800 kcal ME/kg was also formulated. The diet with the reduced crude protein was supplemented with different levels of protease (0.05, 0.075 and 0.1%). Six birds from each treatment were randomly selected and placed in individual digestion cages. They were fed with their respective diets with chromic oxide as indicator for 7 days. Chromic oxide was added to the different diets at 0.2%. On the 3rd to 6th day of feeding, feces were collected using stainless fecal trays installed under each cage. At the end of the collection period, fecal samples collected from each replicate of treatment were dried then subjected to proximate analysis and chromic oxide determination. Result showed that no significant difference on biweekly feed consumption and overall observations. Reduced CP + 0.1% protease was the highest on the hen day production (93.75%) and the lowest of feed conversion (1.85) while reduced CP + 0.075% protease was the highest of egg weight (58.82 g) and eggshell thickness (0.392 mm). There was no significant difference on digestibility coefficient.   Key words: Acid protease, layer diets, supplementation

Abstract

This research aimed to determine the effectiveness of several types of liquid organic fertilizer (LOF) derived from plant waste and the dose of P fertilizer on the growth and yield of upland rice on degraded acid soil. The treatments consisted of two factors. The first factor (A) was several types of LOF consisting of A1 (control), A2 (LOF containing isolates of P-solubilizing bacteria), A3 (LOF-banana waste), and A4 (A2+A3). The second factor (B) was fertilizer doses consisting of B1 (50% of the recommended dose of P fertilizer), B2 (75% of the recommended dose of P fertilizer), and B3 (100% of the recommended dose of P fertilizer). The treatment combinations were arranged in a factorial randomized block design with three replications. The research results showed that applying either LOF-banana waste or the mixture of LOF-banana waste and LOF-containing isolates of P-solubilizing bacteria improved plant height, the number of tillers, and N and P uptake by the plant. The rice grain yields among the treatments were not significantly different, but the highest rice grain yield (139.8 g/pot) was obtained at the treatment of the mixture of LOF-P isolate + LOF-banana waste (A2+A3 treatments). The 75% of the recommended dose of P fertilizer was not significantly different from 100% P fertilizer with LOF on growth and yield upland rice and nutrient uptake by the plant.

Suretno ND, Tambunan RD, Novitasari E. 2022. Production capability of panicum maximum cv gatton grass on dry land of Lampung Province. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 922-928. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The ability of forage plants to adapt differently to different types of soil. Soil type will affect the availability of groundwater, where groundwater is a limiting factor for plant growth. Limited groundwater causes drought stress in plants that disrupt plant growth and biomass production. Based on these differences in adaptability, this study aimed to determine the production capacity of Panicum maximum cv Gatton grass planted on dry land. The study was conducted at Natar Agricultural Science Park, South Lampung Regency, Lampung Province. The material used is Panicum maximum cv Gatton grass which was arranged in a completely randomized design with four replications. The planting distance of grass was 0.5 x 0.5 m2. Harvesting was performed when the grass was four months after planting, with five clumps per replication. The morphological character parameters measured included plant height, stem height, leaf length, leaf width, stem diameter, and the number of branches. Productivity parameters were seen based on the number of tillers and fresh clump weight. The results showed that for morphological parameters, as follows: the average plant height of Panicum maximum cv Gatton grass was 123.74 cm; stem height 90.65 cm; leaf length 26.64 cm; leaf width 1.46 cm; rod diameter 3.91 mm; and the number of branches 4.4. As for the productivity parameter, the average number of tillers was 42.15, with a fresh weight of grass per clump of 0.86 kg. It is concluded that Panicum maximum cv Gatton grass is a medium-type Bengal grass cultivar which has good production capability when planted on dry land.
