Abstract This study aimed to determine the quantitative characteristics, the determinant of body size and shape, and the correlation of body measurements and the bodyweight of Bali and Simbal cattle in Renah Pamenang, Merangin District. The survey method was used along with purposive sampling, the samples were Bali and Simbal cattle aged I1 (Incicivus 1) and not in pregnant condition, with 60 cattle consisting of 30 males and 30 females. Observed data included: body weight, body weight gain, body length, shoulder height, chest circumference, chest weight, chest width, hip height, and canon circumference were analyzed using the t-test method. The principal component analysis was used to determine the determinant of size and shape of Bali and Simbal cattle followed by the regression and correlation analysis to determine the relationship and closeness of the relationship between body measurements with body weight. The result showed that the body weight, body weight gain, and body size of Bali cattle were significantly different (P <0.05) from Simbal. The body weight, body weight gain, and body size of Bali cattle were lower than Simbal cattle. The main characteristic of size in Bali and Simbal cattle was the Chest Circumference. The dominant characteristic of shape in Bali and Simbal cattle was shoulder height. The highest correlation between body measurements and body weight in Bali and Simbal cattle was the chest circumference.

Jumlah sampel 60 ekor ternak sapi bali dan 60 ekor ternak sapi simbal. Data yang dihimpun: bobot badan, panjang badan, tinggi pundak, lingkar dada, dalam dada, lebar dada, tinggi pinggul, dan lingkar kanon. Data yang diperoleh dianalisis menggunakan uji t, Analisis Komponen Utama, serta analisis regresi dan korelasi. Hasil penelitian bobot badan dan ukuran-ukuran tubuh sapi bali dan sapi simbal berbeda nyata (P<0,05). Rataan bobot badan sapi bali jantan dan betina adalah 203,58 ± 18,68 kg, 190,43 ± 11,16 kg lebih rendah dari sapi simbal jantan dan betina adalah 379,883 ± 49,14 kg, 350,033 ± 31,41 kg. Faktor penentu ukuran tubuh sapi bali dan sapi simbal jantan dan betina adalah lingkar dada. Korelasi tertinggi antara ukuran-ukuran tubuh dengan bobot badan pada sapi bali dan sapi simbal jantan dan betina adalah lingkar dada. Kesimpulan, karakteristik morfometrik dan bobot badan sapi bali lebih rendah dibandingkan dengan sapi simbal.  

This study aims to determine the association of quantitative characteristics with growth hormone gene (GH gene) in kerinci duck using PCR-RFLP method. Samples total used was 96 Kerinci ducks consisting of 43 males and 53 females and 96 blood samples. DNA was extracted using the protocol Genomic DNA Purification Kit from Promega and then amplified by PCR using a pair of primers5&#39;-CAA GGA ACA GAG GGT TTC CA-3&#39; and Revers : 3&#39;-GGG AGA TAG GGC AAA CAT CA-5&#39;, with a length of product 855 bp. The amplification product was cut using restriction enzyme AluI with the AG↓CT cutting site. Growth hormone/AluI fragments of Kerinci duck were electrophoresed using 1.5% agarose gel and visualized using doc gel. Data collected includes body weight, weight gain, body measurements, and blood of Kerinci ducks. The differences in body weight, body weight gain, and body measurements, as well as differences in body weight between genotypes were tested by T-test. The determinants of the size and shape of Kerinci duck were analyzed using PCA. This study showed that the body weight, weight gain, and body sizes of male Kerinci ducks were significantly different (P&lt;0.05) than female Kerinci ducks. The Kerinci duck GH|AluI gene is polymorphic with three genotypes, i.e, +/+ of (49%), +/- of (39.6%), and -/- of (11.5%), and two alleles, namely (+) by 69% and (–) by 31%. Conclusion: body weight, weight gain, and body sizes of male Kerinci ducks were higher than female. The size identifier of male and female Kerinci ducks were sternum, shank lengh, and shank circumference, while shape identifier was wing length. GH Genes|AluI in Kerinci duck is polymorphic. GH gene |AluI of Kerinci ducks was associated with body weight, weight gain, and body measurements, and the best is the genotype (+/+).

This study aims to characterize the phenotype and determine the diversity of the Myostatin (MSTN) gene at Bangkok chickens using the Polymerase Chain Reaction- Restriction Fragment Length Polymorphism (PCR-RFLP) method. This study used 50 Bangkok chicken blood samples taken from the axillary vein on the wing. DNA was extracted using the protocol Genomic DNA Purification Kit from Promega and then amplified by PCR (polymerase chain reaction) using a pair of primers F: 5'GGT TTT GAC GAC ATG AGC CT3' R: 5'CAG GTG GAA TGT CAT GCA GA3' with product length 955 bp. Amplification products were cut using restriction enzyme MboI with cutting site ↓GATC. MSTN|MboI fragments of the Bangkok chicken were electrophoresed using 2% agarose gel and visualized using doc gel. The average difference test (T-test) on body weight and weight gain of Bangkok chickens from DOC to 3 months by gender. Polymorphism analysis includes allele frequency and genotype. Male and female Bangkok chickens have low phenotype diversity. The MSTN|MboI gene fragment is monomorphic with band positions of 492 bp, 244 bp, and 219 bp resulting in a genotype of ++, and there is one type of allele with a + allele frequency of 100%.

Penelitian bertujuan untuk mengetahui kemampuan pelepah sawit fermentasi dengan prolinas (PSFP) sebagai pengganti jerami jagung dalam ransum sapi perah dan melihat pengaruhnya  terhadap kualitas susu sapi perah PFH.  Penelitian ini menggunakan sapi perah PFH  laktasi ke 4 sebanyak 4 ekor. Penelitian ini menggunakan rancangan bujur sangkar latin (BSL) dengan 4 perlakuan dan  4 periode sebagai ulangan. Perlakuan  terdiri dari P0: Hijauan 55% + Konsentrat 45% (kontrol), P1: Hijauan 55% ( 90% jerami jagung + PSFP 10%) + 45% Konsentrat, P2: Hijauan 55% ( 80% jerami jagung + PSFP 20%) + 45% Konsentrat, P3: Hijauan 55% ( 60% jerami jagung + PSFP 40%)   + 45% Konsentrat. Peubah yang diamati adalah kadar bahan kering, protein, lemak dan bahan kering tanpa lemak susu sapi perah PFH.  Data dianalisis menggunakan program  SAS. Hasil penelitian menunjukkan bahwa perlakuan subtitusi jerami jagung dengan pelepah sawit fermentasi dengan prolinas tidak mempengaruhi (P>0,05)  kadar protein susu tetapi nyata menurunkan (P<0,05) kadar bahan kering dan bahan kering tanpa lemak susu tetapi  meningkatkan kadar lemak susu. Dari hasil penelitian ini dapat disimpulkan bahwa subtitusi jerami jagung dengan pelepah sawit yang difermentasi dengan prolinas meningkatkan kadar lemak susu sapi perah.Kata kunci:  Pelepah sawit, prolinas, kualitas susu.
