in order to study on the effect of incomplete sire's pedigree on the prediction of breeding value and estimation of genetic trend, two quantitative traits such as weaning weight and average daily gain with heritabilities 0.15 and 0.30 were simulated. phenotypic, genetic and environmental correlations were assumed 0.5. resulted data files with different proportion of missed sire pedigree (0...

Rice (Oryza sativa L.) is one of the most significant cereal crops, about 3 billion people, nearly half the world's population; depend on rice for survival and it offers up to 80% of daily energy intake in most of the Asian countries. Knowledge of the distribution, extent and pattern of genetic variation is useful for estimation of any possible loss of genetic diversity and its role in breeding...

the main objective of this study was to investigate the economic efficiency of investment in sugar beet breeding research in iran. the required information including the value and cost of sugar beet production in 2010 and the budget allocated to the sugar beet breeding research were obtained from the office of statistics and information technology of ministry of jihad-e-agriculture and agricult...

This paper discusses when to start and stop breeding cows in their lactation. First, a review of the literature on the optimal voluntary waiting period (when to start breeding cows) shows that there is not much consensus on how long the economically optimal voluntary waiting period is. Secondly, the paper then describes a computer program that calculates the insemination value (IN$) for cows in...

BACKGROUND Milk proteins genes have been the focus of the researches as the candidate target genes that play a decisive role when animal breeding is desired. OBJECTIVES In the present study, the transcriptional levels of Beta-lactoglobulin (BLG) and Alpha S1 casein (CSN1S1) genes were investigated during prenatal, milking and drying times in mammary glands of the Adani goats which showed high...

Introduction Today, a wide range of molecular tools and powerful computers provides us with an unprecedented capacity to generate data that reveals the architecture of genomes, genes, traits, and how these contribute to the value of the germplasm units (populations, lines, varieties, hybrids, cultivars) used in breeding programs. Complementary work is characterising the key environmental variab...

Reliable selection criteria are required for young riding horses to increase genetic gain by increasing accuracy of selection and decreasing generation intervals. In this study, selection strategies incorporating genomic breeding values (GEBVs) were evaluated. Relevant stages of selection in sport horse breeding programs were analyzed by applying selection index theory. Results in terms of accu...
