    Abstract This study was conducted to determine the improvement of the Bali cattle population in smallholder farms based on the structure of population. This research was carried out from September to November 2019 at the Maiwa Breeding Center Partnership, Enrekang Regency. The type of research used was descriptive research, which we study that describes the variable condition, that are birth rates, mortality, sales, purchases, and population structure at the smallholder farm. The first stage was to collect data by direct observation in the field. The second stage was to carry out tabulation and data analysis. The results of the research were that the increased of Bali cattle at the Maiwa smallholder farm partnership in Maiwa Breeding Center in Enrekang Regency was influenced by calving rate of cows. The calving rate was founded  was 23% in 2017, 32% in 2018, and 46% in 2019, respectively. The mortality rate and sales of cattle was 6%in 2017, 4% in 2018 and 17% in 2019, respectively. The population dynamics was affected by calving rate, mortality and sales livestock in a year. Prediction of population growth increased gradually (7% a year) from 2020 to 2025 based on the population structure of Smallholder Farm in 2019. It is expected that the calving rate is at least 60% in a year. Keywords : Population dynamics, calving rate, mortality rate, birth rate, population growt

    Growth hormone receptor (GHR) is one factor affecting animal growth. GHR is required by growth hormone (GH) to carry out its effects on target tissues. The objective of the study was to estimate genetic diversity of the GHR|AluI gene in Bali, limousin, simmental and pesisir cattle. Genotyping was performed on 248 animals, including 162 Bali, 21 limousin, 17 simmental and 48 pesisir. Single nucleotide polymorphisms (SNP) had been found in exon 10, coding for the cytoplasmic domain of GHR, which was located at position 81 bp (A/G) induced amino acid substitutions Ser/Gly. Genotype frequencies of Bali cattle AA (0.988), GG (0.006) and AG (0.006) were evidenced for the GHR AluI monomorphism, but mostly different from limousin GG (0.667), AA (0.238) and AG (0.095), simmental AG (0.529), GG (0.471) and AA (0.000), pesisir AA (0.604), GG (0.375) and AG (0.021) were the evidence of polymorphism. Homozigosity (monomorphism) in Bali cattle might be affected by adaptability in extreme environmental conditions such as poor nutrition and improper management practices. It also could be affected by natural selection and phenotype plasticity phenomena

    Calf birth weight (CBW) is one of the important selection criteria to predict mature body weight and for calving ease in beef cattle. The GH and GHR genes are considered as candidate genes responsible for growth traits in cattle. The objectives of this study were to identify the polymorphism of GH|MspI and GHR|AluI genes and its association with CBW in Grati-PO cattle. A total of 186 Grati-PO cattle raised by BCRS from May to December 2017. Genomic DNA were isolated from whole blood and used in genotyping analysis using the PCR-RFLP method. The result showed that the average of CBW of Grati-PO cattle in present study was 25.58¬Ī3.31 kg. There was no statistical difference for CBW between male and female. The genotype frequency of CC, CT, and TT of GH gene were 1.1, 18.8 and 80.1 %, respectively and allele frequency of C and T of the GH gene were 0.105 and 0.895, respectively. While the genotype frequency of AA, AG, and GG of GHR gene were 66.1, 25.3 and 8.6 %, respectively, and allele frequency of A and G of GHR gene were 0.788 and 0.212, respectively. It concluded that both GH|MspI and GHR|AluI gene are polymorphic but not significantly associated with CBW in Grati-PO cattle
