Abstract Nutrition of breeding female birds can influence egg quality and is therefore extremely important for the development of the embryo and the successful hatching of a high quality chick. We investigated the effect of combining different levels of dietary energy and protein, with accompanied amino acid levels, in the diets of female ostriches on the composition of their eggs. Ninety pairs...

Mormyrid electric fish rely on the waveform of their electric organ discharges (EODs) for communicating species, sex, and social status, while they use the sequences of pulse intervals (SPIs) for communicating rapidly changing behavioral states and motivation. Little is known of electric signaling during courtship behavior because of two major difficulties: (1) the fish are not easily bred in c...

Improving feed efficiency in dairy cattle could result in more profitable and environmentally sustainable dairy production through lowering feed costs and emissions from dairy farming. In addition, beef production based on dairy herds generates fewer greenhouse gas emissions per unit of meat output than beef production from suckler cow systems. Different scenarios were used to assess the profit...

Objectives To assess the cost-effectiveness of uterine artery embolisation (UAE) and myomectomy for women with symptomatic fibroids wishing to avoid hysterectomy. Design Economic evaluation alongside FEMME randomised controlled trial. Setting 29 UK hospitals. Population Premenopausal who had amenable UAE or 254 were (127) (127). Methods A within-trial cost–utility analysis was conducted from pe...

Maximization of genetic gain in forest tree breeding programs is contingent on the accuracy of the predicted breeding values and precision of the estimated genetic parameters. We investigated the effect of the combined use of contemporary pedigree information and genomic relatedness estimates on the accuracy of predicted breeding values and precision of estimated genetic parameters, as well as ...

Genomic selection (GS) as theoretically introduced by Meuwissen et al. (2001) has been successfully implemented worldwide in dairy cattle breeding programs reflecting large populations, i.e., Holsteins, Fleckvieh, Jersey, and Brown Swiss, and has revolutionized conventional breeding schemes. Revolution of dairy cattle breeding programs via GS was the logical consequence due to the obvious possi...

Rhizomania disease is one of the most important diseases of sugar beet in Iran and many other parts of the world, and plays an essential role in decreasing sugar yield in fields. The best approach to control this disease is to use resistant varieties. For the involvement of resitance genes in breeding programs, tagging these genes by molecular markers is necessary. In this approach, some breedi...

Recognition of genetic reserves and desirable genes is the basis of breeding programs. So far, in Iran, due to the lack of recognition of genetic resources, a considerable breeding program has not been done on native plants. The study of the genetic diversity of violets as a native plant with ornamental and medicinal uses is the great importance in advancing the breeding goals of this plant. So...
