Alterations in some clinical biochemistry values of Honamli and Native Hair goats during pubertal development

WOS: 000369517400006Honamli goats have been defined and recorded as a new breed but the literature is very limited on these goats. In terms of meat production, they have been reported as having some of the highest potential among the goat breeds in Turkey. The aim of the present study was to determine the alterations in blood serum chemistry values in the puberty period in Honamli and Native Hair goats. Selected biochemistry parameters were chosen due to their association with meat production potential. Blood samples of Honamli (n = 90, 45 animals for each sex) and Native Hair goats (n = 90, 45 animals for each sex) were obtained from goat herds in the Western Mediterranean region of Turkey. The values of alkaline phosphatase (ALP), alanine transaminase (ALT), aspartate transaminase (AST), creatine kinase (CK), calcium, cholesterol, creatinine, iron, magnesium, phosphorus, total lipids, triglycerides and uric acid were measured in the sera obtained from blood samples of males and females in equal numbers of each species, in the three age groups of 4, 8 and 12 months. One-way analysis of variance and the Tukey test were performed for statistical evaluation. In both male and female animals, ALT, AST, CK, calcium, cholesterol, creatinine, iron, magnesium, phosphorus, total lipids, triglycerides and uric acid levels exhibited significant (P<0.05) differences between the age groups. Our findings suggest that there are age-associated parallel increases of ALT values in female goats and total lipid values in male goats. The present study also reveals that the analyzed biochemical values usually change after 4 months of age when compared with the other age groups.Scientific and Technological Research Council of Turkey (TUBITAK-TOVAG)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [112O939]; TUBITAK-TOVAGTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK)This article is a part of the project funded by the Scientific and Technological Research Council of Turkey (TUBITAK-TOVAG; Project no.: 112O939).

Melatonin receptor 1A gene RsaI and inhibin alpha subunit gene HaeII polymorphisms in Honamli and Hair goat breeds reared in Western Mediterranean region of Turkey

The melatonin receptor 1A (MTNR1A) and inhibin alpha subunit (INHA) genes play a significant role in the reproductive characteristics of animals. Blood samples were collected from 371 goats (Honamli and Hair) reared in Antalya and Burdur. The polymerase chain reaction (PCR) products were digested by RsaI for the MTNR1A gene and HaeII for the INHA gene. Two alleles (A and G) and three genotypes (AA, AG, and GG) were observed for the INHA gene, while two alleles (R and r) and two genotypes (RR and Rr) were observed for the MTNR1A gene. The highest allelic frequency value for G (91.8%) was found in Honamli goat breeds for the INHA gene while the highest value for R (98.1%) was found in Hair goat breeds for the MTNR1A gene. The GG genotype for the INHA gene and the RR genotype for the MTNR1A gene were identified as the most common genotypes of the Honamli and Hair goat breeds. The rr genotype for the MTNR1A gene could not be determined in the breeds. Both Honamli and Hair goat breeds were in Hardy-Weinberg equilibrium for the genes that were studied. In conclusion, this study confirms the existence of genetic polymorphism in the MTNR1A and INHA genes as detected by PCR-RFLP analysis in Honamli and Hair goat breeds

Identification of beta-Lactoglobulin Gene SacII Polymorphism in Honamli, Hair and Saanen Goat Breeds Reared in Burdur Vicinity

This study was conducted to determine DNA-polymorphism of a SacII RFLP at exon 7 of the beta-lactoglobulin (beta-LG) gene in Honamli (31), Hair (39) and Saanen (41) goat breeds. A total of 111 goats were genotyped for the beta-lactoglobulin-SacII polymorphism by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). In the studied breeds, digestion of amplification product with SacII restriction enzyme revealed two alleles namely, A and B and three genotypes (AA, BB and AB). Allelic frequencies for Hair, Saanen and Honamli breeds were 0.42, 0.37 and 0.53 respectively for A allele; 0.58, 0.63 and 0.47 respectively for B allele, while genotypic frequencies were 0.13, 0.12 and 0.19 for AA, 0.28, 0.39 and 0.13 for BB, and 0.59, 0.49 and 0.68 for AB respectively. Deviation from Hardy-Weinberg equilibrium was not observed in the studied breeds. As a result, this study provided information on the polymorphism of beta-lactoglobulin in three goat breeds. Additionally, this study reported the existence of a genetic polymorphism at beta-LG gene in Honamli goat breed for the first time

Goat production systems of Turkey: Nomadic to industrial

12th International Goat Conference (ICG) -- SEP 25-30, 2016 -- Antalya, TURKEYWOS: 000435750100004Goats play an important socio-economic role in many marginal rural areas of the world. Indigenous goat breeds have taken an important role in the livelihood strategies of impoverished farmers, especially those in harsh, remote areas. Those roles include their use as security and diversification of assets, social and cultural functions. They are also valued for their productive performance, adaptation and disease resistance. Turkey is one of the leading countries in the world for goat population and production. Hair, Kilis, Angora and Shami are the main goat breeds of the country. Hair goats are raised in many parts of the country but are concentrated particularly in the mountainous regions country, while the Angora breed is concentrated mainly in Central Anatolia. Kilis and Shami goats are known for their higher milk yield and litter size and are mainly focused in the south-east region of Turkey. Apart from these four breeds, the minor breeds such as Honamli are located in the Bolkar Mountains in the Mediterranean region (specifically Antalya, Isparta and Konya) and the Norduz breed in Van province. A limited number of dairy goats such as Mainz, Saanen and their crossbreds are located in the Aegean and Marmara regions of Turkey. The population of goats in Turkey is about 11 million head. Hair goats make up approximately 10 million of the total number and the rest make up the balance. There are many reasons for goat production in Turkey, including the country's geography and ecological condition, as well as the socio-economic situation of the rural communities. Goats have been raised in the Anatolian Plateau for many centuries providing dairy, meat, hide and hair to the inhabitants. It is the main source of animal protein for the rural masses in the mountainous regions of the country and less so for the urban population. Goats provide approximately 3% of the total red meat, 2.5% of the total milk and 18.5% of the total hide production for Turkey. They are also the only source of mohair and animal hair production in the country. Although their number and economic significance has decreased over the years, goat breeding still plays and important socio-economic role for the people living in remote areas of Turkey. Investments in intensive goat enterprises have increased significantly in the last few decades in Turkey although marketing margins across the value chain between producers, middlemen, processors, and consumers unjustifiably irregular.Turkish Minist Agr & Livestock, Cukurova Univ, Sheep & Goat Breeder Assoc Turke
