Some Practical and Biotechnological Methods for Improving Reproduction Traits in Sheep
However, reproduction in sheep is seasonal, many breeds of sheep are able to mate not only in autumn, but out-of-season as well. The main factor determining seasonality is the photoperiod, but other factors can influence reproductive pattern, such as genetics, management practices and social cues. The fertility of spring and early summer breeding is usually lower; this imposes the need for alte...
متن کاملAssociation of Melatonin Receptor 1A Gene Polymorphisms with Production and Reproduction Traits in Zandi Sheep
Melatonin regulates some major physiological processes such as maturation and function of reproductive system, pubertal development, seasonal reproduction and adaptation. The activation of melatonin hormone is mediated by melatonin receptor. Previous studies showed melatonin receptor 1A gene (MTNR1A) is highly polymorphic in seasonally breeding species. The aim of the present study was detectio...
متن کاملStudy on sexual reproduction and some morphological and pathological traits of Ophiognomonia leptostyla in Iran
Walnut anthracnose caused by Ophiognomonia leptostyla is the most important and prevalent fungal disease in most walnut growing areas in Iran. Seventy-five isolates of Ophiognomonia leptostyla, causing walnut anthracnose, were obtained from Juglans regia from various regions of Iran. In order to study the sexual reproduction of the fungus, the isolates collected from various parts of Iran were ...
