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 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.

Abstract

This research was conducted to study the influence of kapok seed oil (KSO) supplementation oncellulolytic enzyme and microbial fermentation activity. Sheep rumen fluid was used as enzyme sourceand inoculant, whereas carboxymethylcellulose (CMC) was used as the substrate. There were 4 levels ofKSO supplementation as treatment, i.e. : 0% (T0), 5% (T1), 10% (T2), and 15% (T3). Two measuredvariables were reduced sugar production rate and gas fermentation production. The data were analyzedby analysis of variance in completely randomized design. The result showed that reduced sugarproduction rate in T0, T1, T2 and T3 treatment groups were 2.58; 2.93; 2.08 and 1.58 mg/gCMC/minute, respectively, whereas gas production were : 15.97; 13.26; 10.54 and 7.57 mg/g CMC,respectively. Kapok seed oil supplementation up to 5% DM of cellulose substrate (CMC) did notinfluence the ruminal cellulolytic enzyme activity. The KSO supplementation level 10% - 15%decreased the ruminal cellulolytic enzyme activity.

Abstract

This research was conducted to study the influence of protected kapok seed oil (PKSO)supplementation in its combination with concentrate, in this case was rice bran (RB) on lipid content ofthin tailed sheep received field grass as basal feed. A number of 24 heads of male thin-tailed sheep wereused as experimental material. These sheep were divided into 8 treatment groups. There were twotreatment factors, i.e. : PKSO supplementation (S) as factor I and RB supplementation (K) as factor II.Factor I consisted of 2 levels, i.e. 0% (S0) and 10% (S1), whereas factor II consist of 4 levels, i.e. 0%(K0), 15% (K1), 30% (K2) and 45% (K3), respectively, based on dry matter (DM) intake. Severalvariables were measured, namely content of intra muscular fat (IMF), iodine number of muscular fattyacid, content of meat cholesterol and omega 6 fatty acid (in this case linoleic acid). The collected datawere statistically analyzed by analysis of variance with factorial treatment pattern (2 x 4) in completelyrandomized design (CRD). Content of IMF in sheep supplemented with 0 and 15% KSO levels was notsignificantly different from those without kapok seed oil (KSO) supplementation at the same level ofRB feeding (3.45 and 3.99% vs 3.01 and 3.75%). Supplementation of protected KSO in combinationwith 30 and 45% RP resulted in significantly increased (P < 0.05) IMF content (4.75 and 5.93% vs 4.32and 5.40%) and significantly decreased (P < 0.05) meat chollesterol content (62.46 and 65.26 mg/100 g vs 89.21 and 72.63 mg/100 g ) also significantly increased (P < 0.05) linoleic acid proportion (15.52 and18.25% vs 3.68 and 4.04%) and iodine number (12.52 and 10.25 vs 4.09 and 4.98).

Abstract

The study aims to utilizing mollases as reducing sugar to bind ammonia from urea through maillard reaction in high temperature as a source of Non-protein nitrogen (NPN) slow release in order to improve the efficiency of NPN and of the avaibility of total protein. The study used mollases and cow rumen fluid from Ungaran slaughterhouses. The method of the study was factorial complate random design with 2x3 treatments and 3 replications. The treatments were A0B1 (mollases-urea non heated 1 hour incubation), A0B2 (mollases-urea non heated 3 hour incubation), A0B3 (mollases-urea non heated 5 hour incubation), A1B1 (mollases-urea heated 1 hour incubation), A1B2 (mollases-urea heated 3 hour incubation) and A1B3 (mollases-urea heated 5 hour incubation). The data were analyzed using analysis of variance (ANOVA). The results showed that NH3, Volatile Fatty Acids (VFA) and total protein production in different hours of incubation were significant (P<0,05), meanwhile production in mollases heat treatment and interaction between them were not significant (P>0,05). The longer the time of incubation, the lower the production. The highest NH3production was found at one hour of time of incubation. The VFA and total protein productions increased along with the increasing time of incubation with highest production was found at 5 hours of time of incubation. Keywords : Slow release, maillard reaction, NH3, VFA, protein total
