Body condition score (BCS) is a useful tool in assessing the energy status of dairy cattle. Previous research has shown that it is heritable and genetically correlated to reproductive performance. Currently, interest exists in developing selection indexes for fertility that include BCS information. Before such indexes are developed, it is important to assess the genetic covariance between BCS a...
A method is proposed to transform the red and near infrared data into a soil index in order to map soil features. The index maximises soil variation and helps improve soil feature mapping while it suppresses spectral response from vegetation cover. Geo-statistical analysis of fi eld data, on the other hand, helps understand spatial dependency pattern and map it, which may not be directly visibl...
in this study which was carried out in 1974 in the province of isphahan a total of 23,273 individuals in the cities, and 18,671 individuals in the villages of the same area were studied. results show that the median age in rural area is 16 and in urban area is 18 years. the birth rate in rural is 27.7 per thousand were as the same rate in urban area is 40.2 per thousand. similarly the general f...
Conventional wisdom arguably suggests that parenting is satisfying for parents: individuals in early to mid adulthood often claim to look forward to entering parenthood and having children, and even in contexts of highly developed societies where childbearing has become financially expensive and are associated often with considerable trade-offs in terms of professional careers and pursuing othe...
The teratogenic potential of Liv.52, a commonly used liver protective and rejuvenating agent of herbal “Ayurvedic” origin, was studied. The crude powder suspended in normal saline was administered orally to female pregnant rats in a dose of 100 mg/100 g of body weight during the entire period of gestation. This dose of Liv.52 had no adverse effect on body weight, growth and size of the offsprin...
Background: Fatty acids are known to be critically important in multiple biological functions. Phospholipid fatty acids of follicular fluid, an important microenvironment for the development of oocytes, may contribute to the women’s fertility and the efficacy of assisted reproduction techniques. The aim of this study was to investigate the effect of fatty acid composition of follicular fluid ph...
Background: The male antifertility activity of Gossypol, the active ingredient of cotton seed, inspired the idea for development of an agent with male contraceptive activity. The result of subsequent studies lead to the discovery of several class of compounds with antifertility activity. In this study the antifertility activity of iso-Propyl and iso-Butyl derivatives of dihydropridine were ev...
