Abstract

The research was conducted to identify Growth Hormone (GH) olymorphism of Limura cattle. The research was conducted in the smallholder at Lancar, Montok and Duko village, Larangan subdistrict in Pamekasan district, East Java Province and Animal Breeding Laboratory of Faculty of Animal Science, Gadjah Mada University in April 2012. Then research used 35 Limura calves and 10 Madura calves (as control). Blood samples for DNA molecular analysis, i.e. DNA isolation with SDS-PK modification method, DNA amplification with PCR method and genotyping with RFLP method. Identification of GH gene polymorphism was conducted by digesting the DNA fragment of 211 bp extended from the fourthintron region (49 bp) to fifth of exon (162 bp) by AluI enzyme. The result indicated that GH gene of Madura cattle was not polymorphic with frequencies of L allele 1.00 and V allele 0.00. The LL genotype of Madura cattle was 1.00. Frequencies ofL and V allele in Limura cattle were 0.91 and 0.09, respectively. Limura cattle indicated polymorphic with genotype LL 0.83and LV 0.17. As a results, GH gene polymorphism was found in Limura cattle with L allele frequencies higher than V allele. Limura cattles population were not deviated from Hardy-Weinberg quilibrium genetic condition.(Key words: Growth Hormone Gene, Limura Cattle, Polymorphism)

Abstract

The aims of the study was to analyze the phenotype of Ongole Grade, SIMPO, and LIMPO cows based on the exterior characteristics and body size of cattle, and to distinguish the phenotype of the first filial (F1) and the backcross(BC1) of SIMPO and LIMPO cows, reared by farmers at Pacitan, East Java. The study was conducted with purposive sampling method, involving 5 districts: Pacitan, Arjosari, Pringkuku, Nawangan, and Punung. Eighty four farmers asrespondents with total of 100 head cattle were used in the study. The results showed that the dominant coat color in Ongole Grade was white. However, none of crossbreed in F1 and BC1 had white color, but the color phenotype changeto brown and dark brown, which increase the dark intensity. The muzzle color of Ongole Grade was black, and changed to red in BC1. The hoof color’s of Ongole Grade was black, and brown for BC1. The color phenotype of F1 was similarto both color of Ongole Grade and BC1 phenotype. The increasing intensity of coat color in F1 to BC1 indicated that there was a combination of gene from Simmental or Limousin with F1 and BC1which containing of two or several set ofgenes. SIMPO and LIMPO cows had greater body size than those of Ongole Grade cows. The body’s sizes of BC1 was larger than F1 in SIMPO and LIMPO cows, which was influenced by increasing the effect of additive genes from F1 toBC1.(Keywords: Ongole Grade, SIMPO, LIMPO, First filial, Backcross, Phenotype of cattle)

Abstract

This study aims to find the best estimation of body weight (BW) of Aceh cattle by body dimensions i.e. hearth girth (HG), body length (BL) and width height (WH) of Aceh cattle at BPTU-HPT Sapi Aceh Indrapuri. Seventy nine of mature Aceh cattle (three years old), consisted of 40 female cattle and 39 male cattle were used in this study. The results showed that the regression model for the mature male cattle was BW = 2.50 (HG) + 0.19 (BL) + 0.18 (WH) – 197.89 and for the mature female cattle were BW = 1.43 (HG) + 1.51 (BL) + 0.15 (WH) – 195.42. The correlation coefficient (r) between the body dimension and BW was 0.94 and 0.86 respectively for mature male and mature female cattle. The determination coefficient (R2) for the regression model was 0.88 (male) and 0.74 (female), respectively. The mature weight of Aceh cattle could be explain by HG, BL and WH as + 80% (male) and + 70% (female), and the rest was from the unknown factor out of the regression model.

Abstract

Data on live weight (LW) at 550 days of age and body measurements such as withers height (WH), body length (BL) and heart girth (HG) of Aceh bull and heifer have been collected from 79 animals (39 males and 40 females) managed at the Indrapuri’s Breeding and Forages Centre (IBFC) of Aceh Cattle, Indrapuri District, Aceh Besar Regency, Aceh Province, Indonesia to estimate the LW from body measurements. The overall means (+ SD) for LW, WH, BL and HG of Aceh cattle over sexes were 129.37 + 30.84 kg, 96.59 + 7.11 cm, 93.10 + 11.77 cm and 118.15 + 11.08 cm, respectively. The study revealed that HG was the best predictor of LW and this variable alone contributed 70% (female), 86% (male) and 74% (all animals) of the variation in the LW of Aceh cattle. It was concluded that highest determination coefficient (R2) value of simple linear regression model was found on model LW (kg) = -172.47 + 2.59HG (cm), whereas this model were more effective and efficient for predicting the LW of male Aceh cattle.
