Dalmatian sage (Salvia officinalis L., Lamiaceae) is a well-known aromatic and medicinal Mediterranean plant that is native in coastal regions of the western Balkan and southern Apennine Peninsulas and is commonly cultivated worldwide. It is widely used in the food, pharmaceutical and cosmetic industries. Knowledge of its genetic diversity and spatiotemporal patterns is important for plant bree...
Performance of three generation (G0,G1 and G2)of indigenous chicken was evaluated to assess the effect of breeding strategies on the productivity. Data on age at sexual maturity (ASM), body weight at sexual maturity (BWM), body weight at one year of age (BWY), eggs per clutch (EGC), clutches per year (CLY), hatchability on set eggs basis (HAT) and survivability of baby chicks up to sexual matur...
Artificial insemination is practiced extensively with commercial turkeys. This is primarily the result of selective breeding for a heavier and broader-breasted commercial turkey and the consequent inability of toms to consistently transfer semen to the hen at copulation. The broiler industry has not adapted AI to the extent of the turkey industry but it is occasionally used in pedigree lines an...
The review summarizes the production and reproductive performance of indigenous chicken in Ethiopia. Even though total population is high enough (98%) than other exotic crossbreeds, gain from poultry sector still low. Thus, was encountered under free-range systems with low input for sector, which limits profit due to egg production, small size, slow growth rate, late maturity, clutch intensive ...
The objective of the present study was to determine polymorphism within the promoter region of somatotropin receptor genes in indigenous Sistani cattle (Bos indicus) and associations between this polymorphism and breeding value of birth weight. The pedigree structure was included by considering 1173 animals with 600 progeny birth weight data obtained from a Zhark breeding station in Sistan and ...

background: indigenous chickens could serve as precious genetic resources that should be considered in conservation and breeding programs. the major histocompatibility complex (mhc) has a strong association to disease resistance/susceptibility, production and reproduction traits in chicken. therefore, identifying its polymorphism in populations under selective breeding could be used for selecti...
the data of this study were collected by indigenous chicken breeding centers in the west azerbaijan for 11 generations. the (co) variance components, heritability's, correlations between traits and breeding values were estimated by multi-trait animal model using wombat software. the genetic trends of traits over 11 generations of selection, using average function of breeding values per gen...
research results and facts of indigenous sheep production were reviewed with the aim of delivering relevant information for the beneficiaries. the common production system used in ethiopia was the extensive type, which was characterized by small flock sizes and the flock being periodically devastated by diseases. some indigenous sheep groups of the country were characterized and their names wer...
