Our data suggest that benzene and quercetin have direct stimulatory and inhibitory effects, respectively, on basic ovarian functions. Moreover, no protective action of quercetin against the effects of benzene was found. Rather, it was found to enhance the effect of benzene on progesterone release. Therefore, quercetin cannot be considered for preventing or mitigating the effects of benzene on reproductive processes.

Meat chickens are selected for rapid growth for many decades. This fast growth rate causes some welfare problems. Additionally, litter quality is another important factor in chicken welfare. We raised slow-growing broilers as an alternative of fast-growing broilers and we used slatted floor as an alternative of deep litter. Slow growing broilers had better welfare parameters and slatted floor had positive effects on welfare parameters such as foot pad dermatitis and hock joint dermatitis.

Most gene mtDNA 16S rRNA studies were with aquatic organisms, insects, and a few mammalian species; no reports involved cattle. The objective of this research was to characterize the genetic and phylogenetic diversity among 12 cattle breeds utilizing gene mtDNA 16S rRNA. The base percentages of this gene had a strong bias towards A + T. Only transitions or transversions were detected. The phylogenetic analysis indicated the existence of Bos taurus and Bos indicus ancestry in Chinese cattle.

Increasing genetic resistance to gastrointestinal parasite infections in sheep would limit the use of drugs and the emergence of resistant parasites. However, this is a very complex trait. The identification of genomic areas associated with the trait is hindered by genotype–environment interactions. Therefore, it is necessary to obtain information from non-cosmopolitan sheep populations. Here, the West African Djallonké sheep genomic profile is analyzed to contribute to solve this gap.
