Survey of single strand conformation polymorphism of kappa-casein gene in Alpine and Saanen goats in Iran
Journal Title: Animal Science Papers and Reports - Year 2013, Vol 31, Issue 2
Abstract
To study the genetic polymorphism of Îș-casein (CSN3) gene as candidate gene for marker-assisted selection in different domestic livestock species, blood samples were randomly withdrawn from 34 Alpine and 42 Saanen goats. DNA was extracted from blood samples and a 416 bp fragment from exon 4 of the CSN3 gene was amplified by polymerase chain reaction (PCR). PCR products were analysed using single strand conformation polymorphism (SSCP) method. Results indicated that there were two (K1 and K2) conformational patterns with frequencies 0.91 and 0.09 for Alpine and 0.76 and 0.24 for Saanen goats, respectively. A Chi-square test confirmed Hardy-Weinberg equilibrium for the gene in both breeds.

Expression of contractile protein-encoding genes TPM2 and TNNT3 during ontogenesis in pigs raised in Poland
Troponin is a regulatory proteins complex composed of subunits TnC, TnI, and TnT encoded by separate genes â TNNT1, TNNT2 and TNNT3. It is a component of thin filaments (along with actin and tropomyosin), to which calciu...
Polymorphism and structure of exon 2 of caprine melatonin receptor 1b gene and its relations to fertility and seasonal estrus
The first description is presented of nucleotide sequence of exon 2 of caprine melatonin receptor 1b (MT2). No polymorphisms of MT2 gene were detected between high fertility and year-round estrous goat breeds and low fer...
Chemical composition, fatty acid profile, including health indices of intramuscular fat, and technological suitability of the meat of young bulls of three breeds included in a genetic resources conservation programme fattened within a low-input system
Proximate composition and the proportions of 38 fatty acids (FA) were determined in the meat (m. longisimus lumborum and m. semitendinosus) of young bulls of 3 native Polish breeds (Polish Red â PR, White-Backed â WB and...
Economic evaluation of cow-calf herds. I. Calculation methods
Methodology for a comprehensive evaluation of production and economic variables for suckler herd production in Slovakia were developed using herd records from 2008 through 2012. Major characteristics of the production sy...
The concentration of free fatty acids in goat milk as related to the stage of lactation, age and somatic cell count
The study aimed at determining the concentration of free fatty acids (FFA) and some chemical and physical traits of goat milk as related to the stage of lactation, age and somatic cell count (SCC). Used were 60 Polish Wh...
