Our results suggest that estrous cycles may be associated with clock gene expression in the Small-tailed Han sheep (STH sheep). This is the first study to systematically analyze the expression patterns of clock genes of different estrous cycles in ewes, which could form a basis for further studies to develop the relationship between clock genes and the estrous cycle.

The interaction between genotype and environment changes depending on the interaction of the sub-environments. The environments have a hierarchically structured impact. With regard to the growth of the chicks, nutrition seems to have a higher value than red mite infestation. While a clear interaction between genotypes and poultry red mite infestation was observed in ad libitum feeding, the genotypes reacted similarly to infestation under feed restrictions.

Packaging methods (vacuum packaging and modified atmosphere packaging) allow for maintaining high-quality meat during a long period of storage (30 d) under refrigeration conditions. An interaction between the storage time, packaging method, and mesophilic aerobic bacteria and coliform counts was observed. Storage time affected the number of aerobic psychrotrophic bacteria, redness, pH, shear force value, and desirability of the meat's aroma and taste.

This study investigated the interactive effects of weather conditions, transportation time and loading density on carcass damages and meat quality traits of pigs. Pigs exposed to short transportation at low space allocation during hot weather conditions produced the lowest pork quality. Pigs exposed to short transportation at high loading density during cold weather conditions produced the highest pork quality. Hence, weather and transport conditions are of great importance for the pork quality.

This study aimed to detect a potential association between GHR/AluI polymorphism and milk yield and milk composition traits in dairy cows raised in commercial herds using the PCR-RFLP assay. In conclusion, the GHR gene should be regarded as potential candidate genes in marker-assisted selection programs to improve the performance of milk and related traits in Turkey dairy cattle populations.
