The purpose of the given work was to study the dairy efficiency of the delivered, local and crossbreed goats in three different generations (F1, F2 and F3), derived from their crosses, as well as the biochemical composition of milk and some bloodplasma hormones, participating in the process of lactopoez. For the biochemical tests of milk we have selected casein and serumproteins, iron in lactof...

Acetyl-coenzyme A carboxylase α (ACC-alpha) is considered as the key regulatory enzyme in fatty acid biosynthesis. ACC-alpha gene is located on Caprine chromosome 11 and is polymorphic in many goat breeds. In the current study, we aimed to find possible single nucleotide polymorphisms (SNPs) in the exon 1 region of the ACC-alpha gene in Iranian Mahabadi goat breed. Genomic DNA was extracted fro...

The objective of this study was to identify morphological measurements that best distinguish Moroccan Barcha and Atlas goat breeds. Ten measurements (body weight - BW, body length - BL, heart girth - HG, withers height - WH, rump height - WH, back length - BAL, neck length - NL, head length - HL, ear length - EL, and ear width - EW) of 876 adult animals of both sexes (547 Barcha and 329 Atlas) ...

The aim of this study was to investigate allele frequencies at the CSN1S2 locus in two Chinese dairy goat breeds and the effects of its variation on dairy goat economic traits. Seven hundred and eight goats from Xinong Saanen (XS, n = 268) and Guanzhong (GZ, N = 440) breeds were selected. The milk samples of 268 XS goats were collected during the middle of lactation, body size parameters (708 g...

The genetic diversity was studied using microsatellite DNA markers in Laoshan dairy goat (LS), Xinong Saanen dairy goat (SN), Guanzhong dairy goat (GZ), Banjiao goat (BJ) and Guizhou white goat (GW). Within the nine polymorphic loci, allele frequencies, number of effective alleles (Ne), heterozygosity (He), polymorphism information content (PIC), genetic identity (I) and Nei’s standard genetic ...

OINCE its domestication the goat has served man well. As a source of milk, meat, mohair, and skins it has furnished him both food and clothing, and because of its brush-eating proclivities, has spared him untold amounts of hard labor with the brush hook. Since 1900 the Angora goat industry in the United States has undergone rapid expansion. At present it is confined largely to the Southwestern ...

BACKGROUND Transmissible spongiform encephalopathies (TSE) are fatal neurodegenerative diseases of several mammalian species, including humans. In Italy, the active surveillance through rapid tests on brain stem from small ruminants started in 2002 on randomly selected samples of healthy slaughtered animals. Sampling number was proportionally related to the regional small ruminant population. O...

The relationships between goat κ-casein (CSN3) variants and milk composition were studied in 1143 goats from 4 breeds (Camosciata, Frisa, Orobica, Verzasca). Individual milk samples were analysed by isoelectrofocusing. The effect of CSN3 type on protein and casein content was evident, B variant being associated to higher levels of both traits. Since the B variant is mainly present in local capr...

This study was conducted in the Ruminants Research Station, Office of Agricultural Research/ Ministry Agriculture- Iraq to detect CYP17 gene polymorphisms Local and Shami goat, as well establish if SNPs could be associated with some productive reproductive traits such total milk yield (TMY) its components, addition which included litter size fertility. An important single nucleotide (SNPs) (G22...
