A novel selection algorithm for maximizing genetic response while constraining the rate of inbreeding is presented. It shown that proposed method controls by maintaining sum squared contributions at a constant value and represents an improvement on previous procedures. To maintain from all generations are weighted equally this facilitated modifying numerator relationship matrix. By considering optimization many initial mating proportions (the to next generation) not equal their long-term...

Abstract Predicted rate of genetic response for multiple trait breeding objectives from multivariate analyses is compared with that univariate a range schemes, A selection index approximates multipl best linear unbiased prediction (BLUP) animal model utilized. Changes in parameters due to linkage disequilibrium generated by are accounted for. This study shows asymptotic the aggregate value, and its component traits, on predictions, can easily be calculated first generation responses, which...

Gynecological diseases are triggered by aberrant molecular pathways that alter gene expression, hormonal balance, and cellular signaling pathways, which may lead to long-term physiological consequences. This study was able identify highly preserved modules key hub genes mainly associated with gynecological diseases, represented endometriosis (EM), ovarian cancer (OC), cervical (CC), endometrial (EC), through the weighted co-expression network analysis (WGCNA) of microarray datasets sourced...

The expected benefits from optimized selection in real livestock populations were evaluated by applying dynamic algorithms to two of sheep (Meatlinc) and beef cattle (Aberdeen Angus). In addition, the effects introducing BLUP evaluations on population structure, genetic gain, inbreeding investigated. use BLUP-EBV accelerated rates gain Meatlinc, but Aberdeen Angus are not as evident. Although steady increases average coefficient (F) observed, (ΔF) before after introduction significantly...

Domestic cat hepadnavirus (DCH) is an infectious disease associated with chronic hepatitis in cats, which suggests a similarity B virus infections humans. Since its first identification Australia 2018, DCH has been reported several countries varying prevalence rates, but presence Taiwan yet to be investigated. In this study, we aimed identify the and genetic diversity of Taiwan. Among 71 samples tested, eight (11.27%) were positive for DCH. Of these cases, three cats had elevated levels...

Parrot bornavirus (PaBV) is an infectious disease linked with proventricular dilatation (PDD) severe digestive and neurological symptoms affecting psittacine birds. Despite its detection in 2008, PaBV prevalence Taiwan remains unexplored. one of the leading bird breeders; hence, understanding distribution aids preventive measures controlling spread, early recognition, epidemiology, transmission dynamics. Here, we aimed to detect rate assess genetic variation Taiwan. Among 124 birds tested,...

Abstract Managing the rate of inbreeding (ΔF) provides a general framework for managing genetic resources in farmed breeding populations. Methods ΔF have been developed over last five years and they allow attainment greatest expected progress while restricting at same time increase inbreeding. This is achieved by optimising contribution that each candidate selection must to produce next generation. The methods take into account all available performance pedigree information use Best Linear...

SUMMARY Data on ovulation rate and numbers of ova transferable embryos recovered from superovulated cattle sheep were analysed using generalized linear models, quasi-likelihood, restricted maximum likelihood (REML) mixed models (GLMMS). The data pertained to the operation nucleus breeding schemes in commercial application embryo transfer sheep. Results analyses showed that involving Poisson Binomial distributions inappropriate because over-dispersion, quasi-likelihood model negative binomial...

A selection index (I) method was compared with independent culling levels (N), a restriction in the program, using two replicated single generation experiments Tribolium castaneum, which are considered forms of antagonistic selection. The first experiment designed to increase adult weight without changing pupal weight, while second intended improve egg laying weight. In both genetic correlation between traits involved were positive but higher 1 than 2. proportion 10%. 1, effect as expected...
