Abstract

This investigation was conducted to study the influence of the pelleted field grass (FG) toperformance of Java thin tail (JTT) sheep. Twelve heads of male JTT sheep were devided into 3 groups,consisted of 4 heads as replication, respectively. There were three kinds of ration as treatments, namely:fresh FG (T0), pelleted FG (T1), and combination between 85% FG and 15% rice bran (T2). Themeasured variables were: feed dry matter (DM) consumption, in vivo dry matter digestibility (IVoDMD)and in vivo organic mattter digestibility (IvoOMD), molar proportion of partial volatile fatty acids(VFAs), and daily body weight gain (DBWG). Data were analyzed by analysis of variance (ANOVA) incompletely randomized design (CRD). Result of this investigation showed hat feed consumption bysheep received pelleted FG was higher (P< 0.05) than those received FG (513 vs 393 g). Ratio of aceticacid : propionic acid in sheep received pelleted FG was lower (P<0.05) than those in sheep received FG(2.53 vs 3.46). Feeding of the pelleted FG resulted in DBWG significantly differed from combinationbetween FG and rice bran (69 and 72 g), and were higher (P<0.05) than feeding of FG (53 g). Inconclusion, the feeding of pelleted FG resulted the higher DM consumption and ruminal propionic acid,the lower acetic acid : propionic acid ratio, than feeding of fresh FG. Feeding of pelleted FG to male JTTsheep increased the DBWG, equivalent to those by feeding of combination between 85% fresh FG an15% rice bran.

Abstract

The objective of this study was to study the mineral status of Java thin-tailed (JTT) sheep grazed in Mijen-Semarang, Central Java. Six month old of male JTT sheep and paddock with field grass vegetation were used in the research. Fifteen male JTT sheeps were divided into three groups consisting of 5 heads per group, and grazing for 2 month (in early rainy season, late rainy season and dry season, respectively). The measured variables were feed consumption, digested organic matter, mineral (calcium, phosphorus, magnesium, copper, zinc) level in forage, feces, blood, and daily body weight gain. The data were analyzed by analysis of variance with one-way classification. Magnesium and zinc status of JTT sheep were adequate, whereas phosphorus status was deficient in all season. Calcium in early and late rainy season were deficient (7.37 and 7.86 mg/100 mL, respectively), whereas in the dry season was adequate (8.70 mg/100 mL). The copper deficiency was found in dry and late rainy season (with the Serum copper level was 0.62 and 0.51 µg/mL, respectively, and borderline in early rainy season (64.7 µg/mL). Serum copper in the late rainy season was lower (P<0.05) than it in early rainy season and dry season. There were seasonal variation of mineral status of Java thin-tailed (JTT) sheep grazed in Mijen agricultural area, Semarang, Central Java.

Abstract

The objective of the present study was to investigate the effect of feed deprivation over the first 48 h post-hatch on the composition of fatty acids in broiler meat. Sixty 1-d-old Ross chicks were divided to two experimental groups, i.e., birds provided access to feed and water ad libitumimmediately post-hatch until d 35 and birds deprived from feed but not from water over the first 48 h post-hatch. Blood for cholesterol analysis was collected on d 34. The same birds were sacrificed on d 36, and immediately breast meat, abdominal fat, heart and liver were collected and weighed.Feed deprivation over the first 48 h post-hatch retarded (P<0.05) growth performance of chickens, but had no impact (P>0.05) on the abdominal fat, fatty acid profile of meat, total serum cholesterol level as well as the weight of heart and liver of broiler. In conclusion, early post-hatch feeding is a beneficial means to enhance the final body weight of broilers without affecting the meat quality.
THE INFLUENCE OF SEASON AND TOPOGRAPHY ON MANGANESE (Mn) STATUS OF GRAZING JAVA THIN-TAILED SHEEP IN THE AGRICULTURE AREA IN MIJEN OF SEMARANG-CENTRAL JAVA Widiyanto, W.; Kusumanti, E.; Mulyono, M.; Surahmanto, S.

Abstract

The research was aimed to study the manganese (Mn) status of grazing in Java thin-tailed sheep (JTTS),its interrelation with Mn status in the forages and soil, the influence of seasonal factors and landtopography upon the status of respected mineral. Twenty male JTTS of about 6 months old and 2paddocks with field grass vegetation were used in the research. Treatment factor I was topographynamely plain and slope, while treatment factor II was season, namely dry season and rainy season. Thenumber of experimental sheep was divided into 4 groups with 5 heads of sheep for replication in eachgroup and had been grazed for 2 months. The measured variables were soil pH, Mn content in the soil,forage, feces, and blood plasma. The collected data were processed using analysis of variance withfactorial treatment pattern of 2 X 2 in completely randomized design. Mn level in blood plasma of sheepgrazed on plain and slope paddocks were 0.62 and 0.61 mg/l, respectively, in dry season whereas inrainy season were 0.68 and 0.52 mg/l, respectively. Topography did not influence the level of Mn inblood plasma in dry season. Level of Mn in blood plasma of the sheep was lowest in slope area, whereasin plain area was the highest (P<0.05). Manganese level of soil, forage, feces and blood plasma ofexperimental sheep showed the adequate Mn status.
