Abstract

Chromium appears to be an essential trace element since 1959, but its effect on ruminal microbes is not clear yet. This experiment was conducted to study the effects of organic chromium supplementation on rumen fermentation activity. An in vitro technique was held using randomized block design with 13 treatments and 3 replications. There were four kinds of organic Cr used, produced with four different species of fungi as carriers. Fungi used as carriers were Saccharomyces cerevisiae, Aspergillus oryzae, Rhizophus oryzae and "ragi tape". The result indicated that the optimum organic Cr supplementation was 1 mg organic Cr/kg dry matter. Supplementation of 1 mg organic Cr/kg dry matter increased dry matter and organic matter digestibilities. It also tended to increase NH3 and total VFA production. Propionate production increased, which decreased methane production and increased hexose conversion efficiency in several treatments. Each fungus used as carrier of organic Cr resulted in different effects on rumen fermentation activity, but the effects was within a normal range. It was concluded that either Saccharomyces cerevisiae, Aspergillus oryzae, Rhizophus oryzae or "ragi tape" could be used as carrier in organic Cr production. Key words : organic Cr, ruminal microbes, Saccharomyces cerevisiae, Aspergillus oryzae, Rhizophus oryzae, "ragi tape"

Abstract

High environmental temperatures may cause heat stress in poultry. This may increase water consumption, decrease feed consumption and in turn, decrease production level. In addition, high temperature contributes to oxidative stress, a condition where oxidant activity (free radicals) exceeds antioxidant activity. In this research, antanan (Centella asiatica) and vitamin C were utilized as anti heat-stress agents for heat stressed broilers. The research used 120 male broilers of 2 - 6 weeks of age, kept at 31.98 ± 1.940C poultry house temperatures during the day and 27.36 ± 1.310C at night. The data colected were analyzed with a factorial in completely randomized design of 2 x 3 (2 levels of vitamin C, 3 levels of antanan and 4 replications) and continued with contrast-orthogonal test when necessary. The result indicated that the treatments of 5% antanan (A5), 10% antanan (A10), combination of A5C, and A10C significantly (P < 0.05) increased the plasma triiodothyronine hormone from 101 ng/dL to 113, 110, 121, 119 and 126 ng/dL respectively; carcass protein from 16.5% to 17.8%, 19.1%, 19.2%, 17.3% and 18.1%; feed consumption from 2711 g to 3026, 3071, 2883, 3156 and 2935 g and body weight gain from 1181 g to 1297, 1347, 1254, 1376 and 1330 g. It could be concluded that the combination of addition 5% antanan and vitamin C 600 ppm is the most effective as anti heat-stress agent in broilers. Key words : Centella asiatica, vitamin C, heat stress, broiler

Abstract

The aim of this study was to evaluate the effect of superovulation treatment using combination of CIDR, FSH and hCG in beef cattle as donor embryos using MOET programme. All animals had been palpated to evaluated the ovary status and normal cows were used as donor and synchronized with CIDR (Eazy BreedTM). At day 10 of oestrus cycle, cows were divided into two groups, first group: cows were injected intramuscularly with FSH (Antrin) 40 IU per cow with decreasing doses (for 4 days) and second group cows were treated the same way but at day 5 after FSH injection, they were injected intramuscularly with 1,500 IU hCG (Chorulon). Embryo collection was done at day 7 after Artificial Insemination (AI). Average number of corpora lutea (CL) in animals that superovulated with CIDR, FSH and hCG was significantly higher (P < 0.05) compared to animals treated with CIDR and FSH only (5.52). Average number of embryo collection and number of transferable embryos were also higher in group treated with hCG (6.00 vs 5.44) compared with those treated without hCG (4.33 vs 3.17). The conclusion is hCG superovulation injection with CIDR and FSH can increase the respon of superovulation. Key words : superovulation, CIDR, FSH, hCG, beef cattle

Abstract

Fibrous feeds vary in their physical properties. The experiment aimed to clarify the effect of physical properties of fibrous component in rations on feed intake and nutrient digestibility in goats. Rations were composed of 50% fibrous feed and 50% concentrate. The fibrous feed as treatments were as follows: napier grass (RG), rice straw (JP), cocoa pod (KC), mixed rice straw and coffee husk (JK), mixed napier grass, rice straw, coffee husk, and cocoa pod (CP). Rations were offered to four groups of 20 Etawah-grade goats weighing of 13.50±2.14 kg in a randomized block design. Physical properties of the fibrous components of ration and faeces, nutrients intake and digestibility and daily life weight gain were evaluated. Analysis of variance and correlation were applied to analyze data. Dry matter intake varied from 298-440 g/day. Goats offered KC ration had the highest intake. Low feed intake was associated with the low density of the fibrous component. Dietary fat digestibility decreased when the fibrous feed component had low capacity of oil adsorption. Young goats had life weight gain of 50-136 g/day, TDN requirement for maintenance and 50 g daily gain of 63.4 g and 131 g TDN, respectively. The results indicated that physical properties of fibrous component in the rations influenced dry matter intake and nutrients digestibility in growing goats. Key words : physical properties, intake, nutrient, digestibility, goat

Abstract

An experiment was conducted to examine the effect of different levels of tape yeast addition into rations on Rattus norvegicus performance, such as feed consumption, body weight gain, feed conversion ratio and mortality. The experimental design used was a factorial completely randomized design 2 x 4, the first factor was sex (male and female rats), and the second factor was different levels of tape yeast added into rations (0% as R1, 0.5% as R2, 1% as R3 and 1.5% as R4). The results showed that the interaction between sex and yeast addition had significant effect on feed consumption and body weight gain (P < 0.05), but the effect was not significant on feed conversion ratio and mortality. Yeast addition in male-rat rations significantly reduced feed consumption, but did not affect body weight gain. In female rats, the addition of yeast in the rations increased body weight gain. Increasing levels of tape yeast in the rations improved the body weight gain and feed conversion ratio, especially for female rats (P < 0.05). There was no single rat died during the experimental period. Rats fed ration containing 1.5% yeast showed better feed consumption, weight gain, and feed conversion ratio compared to rats given other rations. Key words : rat, tape yeast, consumption, weight gain, feed conversion ratio, mortality

Abstract

The objectives of this present investigation were to evaluate effects of using shell of freshwater snail as major source of calcium in the diets on performance and bone mineralization of growing native chicks (1-12 weeks of age). There were four dietary treatments. The first was a basal diet (negative control) containing 0.5 % bone meal, but deficient in phosphor. Three other diets which were relatively the same in composition as that of basal diet, but one supplemented with 2.5 % oyster shell (positive control) and two with 2.5% shell of freshwater snail obtained from two different water bodies: lake and rice field, respectively. One hundred birds of native chicken were divided into four groups of treatments with five replicates with 5 birds each and offered experimental diets for 12 weeks. Parameters measured included: body weight gain, feed intake, feed conversion ratio (FCR), weight of tibia bone and their ash and mineral (Ca and P) composition and retention. The chicks fed on diets containing shell of freshwater snails showed no significantly difference in body weight gain, feed intake and FCR with those fed on diet containing oyster shell, but significantly lower body weight gain than those fed on basal diet containing only bone meal. Feeding of diets supplemented with shell of snails and oyster decreased significantly the body weight gain. However, no significantly difference was observed in the weight and content of ash, Ca and P of tibia bone. Key words : freshwater snail, native chicken, mineral nutrition, bone mineralization

Abstract

Priangan sheep is a native sheep of Indonesia and considered as a hair sheep. Its main product is meat. Recently, the Priangan sheep is crossed with a Merino sheep to produce the Priangan-Merino crossbred. Since the Merino sheep is considered as a wool sheep, it is expected that the Priangan-Merino sheep will have a better quality of wool than the Priangan sheep. To measure the wool improvement of the Priangan-Merino crossbred, an experiment was conducted. Fifteen Priangan sheeps and 15 Merino crossbreds were used in this experiment. The spinning count and wool yarn staple length were measured. The experimental statistics and the design of the experiment was completely ramdomized design. The results indicated that staple strength of wool yarn of Priangan was not significantly different with that of Merino cross. Spinning count was significantly different (P < 0.01) between breed. Key words : Yarn, Priangan and Merino cross, staple strenght, spinning count
