Background: Growth Hormone (GH) gene codes for the growth hormone, an anabolic hormone synthesized and secreted by the somatotroph cells of pituitary. Growth hormone influences many processes such as growth, lactation, reproduction and metabolism. Genetic variation in the gene are utilized as markers for selecting animals that are superior in terms growth, production and reproduction traits. Information available on the polymorphism of growth hormone gene of Ganjam and Baigani goats of Odisha is scanty. The current investigation was done to explore the genetic variation of this gene and its association with morphometric traits. Methods: Genetic polymorphism in exon 2 and 3 of Growth hormone gene in Ganjam goat and Baigani goat was explored with sample size of 100 goats for each. The goats belonged to three locations: Khallikote, Rambha, Chattrapur of Ganjam district. The goats were recorded for their body weights, morphometric traits and morphological traits. Genomic DNA was isolated, the target segment comprising exons 2 and 3 was amplified and PCR-RFLP was carried out using Hae III restriction enzyme. Genotypes were scored. Result: PCR of the locus resulted in 422 bp PCR product. PCR-RFLP using Hae III restriction enzyme yielded only two variants in both the populations. The variant A had only one restriction recognition site on the target gene segment yielding two bands with size of 366bp and 56bp whereas the variant B did not have any restriction site with single band of 422bp. Three genotypes AA, AB and BB were found in both the population. In both the population, the gene and genotype frequency were significantly deviated from the Hardy Weinberg Equilibrium frequency. There was a significant difference in the genotype frequencies of growth hormone gene between Ganjam and Baigani goats. The AB genotype had higher mean value for all morphometric traits than AA and BB genotype though the differences were not found to be significant.

Abstract. Research to assess the effect of single genes on reproductive traits in bovine species is imperative to elucidate genes' functions and acquire a better perspective of quantitative traits. The present study was undertaken to characterize genetic diversity in the bovine growth hormone (GH) gene in a population of 410 Holstein dairy cows in Tunisia. The analyses were based on single nucleotide polymorphisms, and GH-AluI and GH-MspI detections and genotyping were carried out using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Data were analyzed using a mixed linear model with the MIXED procedure to reveal the possible effect of GH genotypes on reproductive traits. The frequency data of AluI(L//V) and MspI(+//−) alleles were 87.04//12.96 and 70.06//29.94, respectively. The distribution of the frequency of GH genotypes for LL/LV/VV and (−/−)//(+/−)//(+/+) were 77.75//18.59//3.66 and 15.37//29.13//55.50, respectively. The results of the statistical analyses proved that GH-AluI showed a substantial favorable effect on exanimate traits except for the age at first calving; however, only a suggestive effect of GH-MspI on the calving interval (CI) and the days open (DI) was found. The homozygous LL genotype seemed to be advantageous with respect to the CI and the DI compared with LV and VV genotypes. Heterozygous MspI(+/−) cows tended to have a longer CI and DI than MspI(+/+) and MspI(−/−) cows, but the difference was not statistically significant. A significant effect of different GH-AluI–MspI combined genotypes was found on the number of inseminations per conception, the CI and the DI, and the LL/– combined genotype seemed to be associated with better reproductive performance. Based on these results, the LL genotype of the GH locus can be considered to be a favorable genotype for reproductive traits in Holstein dairy cattle, although these findings need to be confirmed by further research before polymorphisms can be used in a marker-assisted selection program.

Abstract. The aim of this paper was to study the polymorphisms of bovine growth hormone gene. The authors genotyped 363 Hungarian Holstein-Friesian bull dams from 6 farms all over the country. Two variants (L and V) of the bovine growth hormone gene digested with AluI enzyme were identified in the experiment. Genotyping was carried out by PCR-RFLP method. The frequency data of L and V allele was 0.93 and 0.07 respectively. Distribution of the three genotypes were 87.05% (LL), 12.40% (LV) and 0.55% (VV). The studied population was in H-W equilibrium considering the genotype distribution. SPSS 11.0 for Windows was used to reveal the possible correlations between GH genotypes and production and reproduction traits and further statistical analyses. On the basis of statistical analyses it can be found that VV genotype cows had the longest milking period and LL had the shortest dry period. Both differences were significant. Cows with LV genotype had significantly higher test milking data than LL cows. Furthermore, LV genotype seemed to be advantageous for 305 days lactation milk yield. While milk composition traits, as 305 days milk fat and protein percent showed the opposite tendency, since LL genotyped dams produced significantly higher values in these traits.

Preliminary Study

SummaryPashmina, internationally known as “cashmere”, a fine luxury fibre, is being produced from Changthangi goats bred in the Ladakh region of India. The Leh district of Greater Ladakh produces around 30 000 kg of pashmina fibre which is harvested from about 0.15 million Changthangi goats reared by the Changpa nomads in Changthang region of Greater Ladakh. Changthangi goats are sometimes also called Changra goats. Pashmina producing goats are of great importance for revitalising the economy of the poverty stricken region of Changthang and the Leh district of Ladakh. The information on Changthangi goats was collected from both small and large-scale farmers in Ladakh, and 337 animals were included in the study.The body colour of Changthangi goats varies from white to light brown and nearly whole body is covered with pashmina and long hairs. The average birth weights of male and female kids were estimated as 2.11 ± 0.3 and 2.06 ± 0.2 kg, respectively while weight at 300 days was found to be 20.0 ± 2.1 and 18.7 ± 1.9 kg in male and females respectively.The pashmina yields of bucks, does, male hoggets and female hoggets were estimated as 402 ± 19 g, 248 ± 14 g, 255 ± 12 and 280 ± 16 g, respectively. The length of pashmina fibre was found to be 4.25 ± 1.2 cm in males and 4.02 ± 1.5 cm in females while fibre diameter in male and female goats was estimated as 12.9 ± 2.6 μ and 13.0 ± 3.0 μ, respectively.The twining rate was found to be very low, nearly 0.3%. A preliminary study at DNA level with PCR-RFLP indicated monomorphism at the growth hormone gene. The occurrence of disease was quite low although some genetic deformities in this breed were not uncommon.

This study was conducted to identify polymorphism of growth hormone gene of Bali cattle. A PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism) procedure was developed for determining polymorphism of growth hormone gene. The DNA was isolated from blood samples by salting out method. Total DNA were amplified with forward primer, 5’-TAGGGGAGGGTGGAAAATGGA-3’ and reverse primer, 5’-GACACCTACTCAGACAATGCG-3’. The PCR product was digested by HaeIII restriction enzyme. Result of the amplification was a specific single band with fragment 450 bp. Restriction with HaeIII restriction enzyme resulted four kinds of haplotype. Haplotype I was not cut by HaeIII restriction enzyme. Haplotype II were cut into two, 225 bp and 150 bp,. Haplotype III were cut into three size, 400 bp, 225 bp and 150 bp. Haplotype IV were cut into five fragments 450 bp, 400 bp, 275 bp, 225 bp and 150 bp.

The present investigation was planned to study growth hormone (GH) gene exon-4 polymorphism using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) in Surti and Mehsani goats. GH gene exon-4 region was found to be monomorphic on restriction digestion with HaeIII, which revealed only one genotype CC in both Surti and Mehsani goat breeds. The allelic frequency of C was 1.00 in both the breeds of goats with absence of D allele.
