Reproductive status of Alburnus chalcoides adults from Anzali Wetland was investigated by histological examination of gonads, assessment of sex steroids (i.e. Progesterone (P), Estradiol-17ß (E2), Testosterone (T)) and reproductive indices (i.e. absolute fecundity, oocyte diameter, hepatosomatic index (%HSI) and gonadosomatic index (%GSI)). Totally, 42 females and 16 males were captured during ...

Growth patterns of 182 cows [73 Angus (AA), 31 Charotais (CC), 38 Charolais x Angus (CA) and 40 Holstein x Angus (FA)] were studied from birth to maturi ty. Breed type significantly affected weight and condition at all ages. Crossbred cows were heavier than AA and lighter in weight than CC cows (P<.01) at all periods. Differences between CA and FA cows were small. The CA cows were somewhat heav...

Litchi is an important fruit tree in tropical and subtropical areas of the world. However, there is widespread confusion regarding litchi cultivar nomenclature and detailed information of genetic relationships among litchi germplasm is unclear. In the present study, the potential of single nucleotide polymorphism (SNP) for the identification of 96 representative litchi accessions and their gene...

According to the requirements of different fertilizers for early-maturing and late-maturing broccoli, this study aimed establish models formula fertilization apply them in recommendation by aid soil testing performed main broccoli-producing areas. In paper, based on effective functions nitrogen- (N), phosphorous- (P), potassium (K)-balanced broccoli two mature types, were established. The recom...

The productivity of breeding colonies of Mongolian gerbils can be substantially enhanced by using as breeding stock only the 40% of females that exhibit vaginal opening before reaching 25 days of age. Early-maturing females are more likely to breed successfully on first pairing. The lifetime fecundity of early-maturing females is more than twice that of their late-maturing sisters. In those cas...
