Abstract

The research aims to evaluate calsium soap protection as feed supplement based on dry matterdigestibility, organic matter digestibility and pH in vitro in the rumen and post rumen. Calsium soapwas produced from sardine fish oil and soybean meal, through two protection methods. It wassaponification and microencapsulation. This research used Split Subject Repeated MeasurementDesign with 3 treatments (calcium soap, soybean meal and pangola grass) which each treatment wasrepeated 5 times. The observation kinetics of dry matter digestibility, organic matter digestibility, andpH rumen fluid were done in incubation times (2, 4, 8, 12, 24 and 48 hours respectively). The firstresults of the research showed that in the first step (rumen) has dry matter digestibility of calciumsoaps: 38.65; 40.00; 42.66; 46.32; 54.40 and 51.40% respectively; organic matter digestibility: 39.44;41.27; 44, 31; 46.32; 56.62 and 52.50% respectively. Kinetics of pH rumen fluid: 6.89; 6.79; 6.78;6.74; 6.71, and 6.88 respectively. In the second step (post rumen), the digestibility of calsium soapproduction has dry matter digestibility of 74.85% and organic matter of digestibilty of 72.94%. Theresults could be concluded that in the rumen, calcium soap is the most microbial degradation resistantcompared the others and it can be degraded and digested in the abomasum to the small intestine.Therefore pH of rumen fluid is optimal, so it does not interfere with the fermentation in the rumen.Keywords: calsium soap, in vitro, dry matter digestibily, organic matter digestibility, pH value

Abstract

This study aimed to determine the effect of medium chain fatty acids (MCFA) on propionic acidsand lamb meat chemical quality. The treatment given was R1: feed without medium chain fatty acids(MCFA), while R2 dan R3 were the feed contained 1.0% and 1.5% of MCFA, respectively. The twelveheads of lambs yearling weight of 16-17 kg were used as materials. Biological trial was done for threemonths and then was slaughtered. Before being slaughtered, the animal was taken rumen fluid to beanalyzed for propionic acid. The carcass was sampled to be analyzed for chemical composition,cholesterol and fatty acids content. This study showed that methanogenic inhibitor feed with 1.0-1.5%MCFA could be used as sheep feed, and the results: the propionic acid content in rumen increased 29.59– 36.11%. The cholesterol content decreased 7.14-10.06%. For the meat fatty acids composition,unsaturated fatty acids increased 9.05 – 17.96%. while saturated fatty acid decreased 6.59 – 11.88%.

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).
