Th e aim of this study was to compare the genetic variation of fi ve local chicken breeds reared in Poland. Twenty-seven microsatellite markers were investigated in 138 birds belonging to fi ve breeds: Miniature Cochin (MCO), Gold Italian (GI), Green Legged Partridge (GLP), Silver Italian (SI) and White Leghorn (WL). One hundred eighty fi ve alleles were detected in the overall population, with...

Since horse breeds constitute populations submitted to variable and multiple outcrossing events, we analyzed the genetic structure and gene flows considering horses raised in France. We used genealogical data, with a reference population of 547,620 horses born in France between 2002 and 2011, grouped according to 55 breed origins. On average, individuals had 6.3 equivalent generations known. Co...

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...

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,...
