The effect of female body color on mate selection by male Mozambique Tilapia (Oreochromis mossambicus) was assessed. A single black or gold male was placed in each of nine spawning net cages along with three gold and three black females. Number of spawns and day of spawns were recorded over a...

An experiment was conducted to evaluate the growth performance of hybrids from a diallel 3 × 3 crossing of Oreochromis karongae, O. shiranus, and O. mossambicus. Fingerlings of 3.47 ± 0.04 g were stocked at 5 fish m^-2 in nine treatments replicated twice. Final weights were significantly different...

Reproduction is a central activity for all living organisms but is also associated with a diversity of costs that are detrimental for survival. Until recently, the cost of cancer as a selective force has been poorly considered. Considering 191 mammal species, we found cancer mortality was more...

Successful reproduction of lactating dairy cattle, or in other words its reproductive performance is a limiting factor in the profit ratio of cattle breeding regarding market production. The aim of this research was to evaluate the success rate of synchronization protocols Ovsynch,...

The aim of this study was to evaluate the effects of dose, start time, and application interval of recombinant bovine somatotropin (rbST) on performance, health, and reproduction parameters of crossbred Holstein × Gyr dairy cows (3/4 and 7/8). A 2 × 2 × 2 factorial study was designed to test the...

The artificial breeding process of razor clams in Shandong and the effects of salinity on the growth of larvae were studied. The results showed that razor clam could be successfully propagated in Shandong, and their fertilized eggs could enter the D-shaped larval stage after 24 h of development at...

Cattle are generally considered a monovular species; however, recently, a bovine high fecundity allele, termed the Trio allele, was discovered. Carriers of Trio have an elevated ovulation rate (3-5), while half-sibling noncarriers are monovular. Carriers of the Trio allele have overexpression in...

Rhythmic contraction of the oviducts is essential for transporting gametes and embryos at peri-ovulation; however, its regulatory mechanism during the estrous cycle is unclear. Meanwhile, it is reported that ion currents regulate muscle contraction. Our study aimed to clarify the involvement of ion ...

Bisphenol A (BPA) is a widely used synthetic industrial compound frequently detected in food. Dietary exposure to BPA has been recognised as a potential health concern. However, there are uncertainties regarding BPA toxicity. The primary objective of this study was to summarise and analyse multiple ...
