ABSTRAKPenelitian ini dilakukan untuk mengkaji pengaruh suplementasi minyak biji kapok (MBK) terproteksi dalam kombinasinya dengan konsentrat, dalam hal ini bekatul terhadap status lipida daging domba ekor tipis (DET) yang mendapat rumput lapangan (RL) sebagai pakan basal. Sebanyak 24 ekor domba DET jantan digunakan sebagai bahan percobaan yang dibagi dalam 8 kelompok perlakuan. Terdapat 2 faktor perlakuan, yakni suplementasi MBK (faktor I) dan suplementasi konsentrat yakni bekatul (faktor II). Faktor I terdiri atas 2 aras, yakni 0% (S0) dan 10% (S1), sedangkan faktor II terdiri atas 4 aras, yakni 0% (K0); 15% (K1); 30% (K2) dan 45% (K3), berdasarkan konsumsi BK. Variabel yang diukur meliputi kandungan lemak intramuskuler (LIM), bilangan iodin (BI) asam lemak daging, kandungan kolesterol dan asam lemak omega 6 daging (dalam hal ini asam linoleat). Data yang terkumpul diolah secara statistik dengan analisis ragam, pola perlakuan faktorial 2 x 4 dalam rancangan acak lengkap (RAL). Kandungan LIM domba-domba yang mendapat suplemen MBK pada aras 0 dan dedak halus 15% tidak berbeda nyata dengan kandungan LIM domba-domba tanpa suplementasi MBK dengan aras pemberian bekatul yang sama (3,45 dan 3,99 vs 3,01 dan 3,75% ABSTRACTThis 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 of thin tailed sheep received field grass as basal feed. A number of 24 heads of male thin-tailed sheep were used as experimental material. These sheep were divided into 8 treatment groups. There were two treatment 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. Several variables were measured, namely content of intra muscular fat (IMF), iodine number of muscular fatty acid, content of meat cholesterol and omega 6 fatty acid (in this case linoleic acid). The collected data were statistically analyzed by analysis of variance with factorial treatment pattern (2 x 4) in completely randomized design (CRD). Content of IMF in sheep supplemented with 0 and 15% KSO levels was not significantly different from those without kapok seed oil (KSO) supplementation at the same level of RB feeding (3.45 and 3.99% vs 3.01 and 3.75%). Supplementation of protected KSO in combination with 30 and 45% RP resulted in significantly increased (P < 0. vs 89.21 and 72.63 mg/100 g ) also significantly increased (P < 0.05) linoleic acid proportion (15.52 and 18.25% vs 3.68 and 4.04%) and iodine number (12.52 and 10.25 vs 4.09 and 4.98).
The aim of the current research was to analyze the population structure and expression of KISS1 gene associated with reproductive traits through Follicle Stimulating Hormone (FSH) level and DNA sequencing analysis based on KISS1 gene. Genotypes of 23 goat does consist of Kacang goats (n=7), Kejobong goats (n=8) and Senduro goats (n=8) were investigated using DNA sequencing, 16 out of 23 samples were synchronized to examine their FSH level using ELISA method. The data were analyzed using MEGA X software for DNA sequences and General Linier Model (GLM) for FSH plasma level. The phylogenetic tree showed the high homology between Indonesian native goats with other species showing a gene conservatism. A significantly higher FSH plasma levels were obtained from Kacang and Kejobong than Senduro goat (P = 0.002), litter size (LS) 3 than LS 1 (P = 0.0175), further CAATGCGCAACGCT haplotype and GA genotype at g.2459 G>A have a higher FSH plasma than other haplotypes and genotypes (P = 0.0027; P<0.0001) and are associated with high LS (3.0±0.18). Neither sample collection times nor parities have different significantly. The current trial indicated that CAATGCGCAACGCT haplotype and GA genotype at g.2459 G>A were correlated with reproductive traits.
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.
This research was conducted to study the influence of kapok seed oil (KSO) supplementation on cellulolytic enzyme and microbial fermentation activity. Sheep rumen fluid was used as enzyme source and inoculant, whereas carboxymethylcellulose (CMC) was used as the substrate. There were 4 levels of KSO supplementation as treatment, i.e. : 0% (T0), 5% (T1), 10% (T2), and 15% (T3). Two measured variables were reduced sugar production rate and gas fermentation production. The data were analyzed by analysis of variance in completely randomized design. The result showed that reduced sugar production rate in T0, T1, T2 and T3 treatment groups were 2.58; 2.93; 2.08 and 1.58 mg/g CMC/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 not influence the ruminal cellulolytic enzyme activity. The KSO supplementation level 10% -15% decreased the ruminal cellulolytic enzyme activity.
This research aimed to evaluated and assessed the effect of the molasses level on organoleptic quality of multinutrient block (MnB). The materials used were corn forage, bentonite, urea, salt, molasses, water, blood clamshell and egg shells. The experimental designed used was a Completely Randomized Design with 4 treatments (T0 = MnB Formulation T0 + 0% of molasses, T1 = MnB Formulation T1 + 20% of molasses, T2 = MnB Formulation T2 + 35% of molases, and T3 = MnB Formulation T3 + 50% of molasses) and 4 replications. The variables observed were moisture content, texture, colored and aroma of MnB. The results showed that the addition of molasses had significantly (P <0.05) improved of MnB organoleptic quality. The conclusion for the study, that the multinutrient block formulation with 50% molasses resulted the best organoleptic quality.
