The purpose of this study is to investigate the complete nucleotide sequence of the mitochondrial genome of the Taiwan Lanyu pig (Sus scrofa) and its phylogenetic relationships with other pig breeds. Thirty-four forward and reverse primers were designed. Sequencing was performed in both directions. The results showed that, the complete sequence of the mitochondrial genome of the Taiwan Lanyu (S...
With companion animals, there is a large diversity in breeding practices, which may impact genetic variability and health of selected breeds. Based on a survey, we illustrate the specificities of scent hound dog breeders regarding either their breeding goals or their mating practices. Mating between close relatives are also investigated in different cat breeds. Such mating are more or less freq...
In modern programmes of animal breeding, the polymorphisms of the milk proteins can be used as marker systems. Beta-Lactoglobulin is the major milk whey protein in the ruminants. The BLG coding gene located on ovine chromosome 3. This protein, synthesis in the mammary glands during pregnancy and the lactation stages. Studies have indicated that this protein is polymorphic in the many breeds of ...
The objective of the present study was to detect polymorphism in follicle stimulating hormone receptor (FSHR) and beta subunit of follicle stimulating hormone (FSHβ) genes and their relation to litter size and body weight trait in Baluchi, Iran black and Arman sheep breeds. PCR-RFLP technique using ACCI and HinfI enzyme treatments employed to detection of polymorphism in FSHβ marker site but de...
The purpose of the study was to detect the AluI and DdeI polymorphisms within POU1F1 gene exon 6 and 3'UTR region in Turkish sheep breeds, and their association with milk productive traits. Jugular blood samples were collected from 50 Sakiz, 50 White Karaman, and 50 Awassi sheep using EDTA as an anticoagulant. PCR-RFLP and sequencing analysis were performed to investigate possible polymorphisms...
Eleven goat breeds of different origin (10 Spanish and 1 African) were considered for this study: Zambian Dwarf, Azpi-Gorri, Blanca-Andaluza, Blanca-Celtibérica, Blanca de Rasquera, Catalana, Malagueña, Moncaína, Murciano-Granadina, Negra Serrana and Pyrenean. Nine linear body measurements for females, as well as the body weight ratio between gender and body weight, were obtained from literatur...

An experiment was conducted to evaluate the impact of different rationale on performance certain attributes Vencov, Hubbard and Croiler breeds. The average feed intake, body weight, weight gain, conversion efficiency, gain at slaughter dressing evaluated. intake were 2.18, 2.02 2.03 kg/bird, in treatments (Ist, IInd IIIrd) it 1.89, 1.76 2.57 kg/bird breeds (Vencov, Croilers) respectively. 1.07,...
We have investigated the origin of swine breeds through the joint analysis of mitochondrial, microsatellite, and Y-chromosome polymorphisms in a sample of pigs and wild boars with a worldwide distribution. Genetic differentiation between pigs and wild boars was remarkably weak, likely as a consequence of a sustained gene flow between both populations. The analysis of nuclear markers evidenced t...
Through thousands of years of breeding and strong human selection, the dog (Canis lupus familiaris) exists today within hundreds of closed populations throughout the world, each with defined phenotypes. A singular geographic region with broad diversity in dog breeds presents an interesting opportunity to observe potential mechanisms of breed formation. Italy claims 14 internationally recognized...
