Consensus from the literature is that heat stress reduces the duration of behavioural oestrus, the incidence of oestrus and the length of the cycle. Although the systematic review of data [19] indicates a decrease in the length of behavioural oestrus by an average of 7.1 h, the timing of...
As noted, fat-tailsheep breedsare tolerant of extreme aridity, whereas cashmere breeds of goats are adapted to an extremely cold environment. View chapter Chapter Breeding climate-resilience crops for future agriculture Climate Change and Crop Stress ...
"The one thing I know for sure is that we can do better than Joe Biden as a person who can deliver our message in this election cycle," Rep. Adam Smith, D-Wash., had previously told ABC News. "And we have time to do that. And we should." “我唯一可以肯定的一件事是,作为能够...
Production animals, such as sheep, which are exposed to high ambient temperatures (> 30 °C) experience heat stress which consequently affects their overall productivity and reproductive performance [9]. Heat stress arises when the effective temperature of the environment exceeds the animals’ upper...
Genes that affect the normal cell cycle are also modified in animals suffering from heat stress condition. The mRNA expressions of p21 and p53 genes involving in the regulation of the cell cycle arrest were reported to be up-regulated during extreme heat stress condition (Sonna et al., 2002)...
The 12 h light (0600 to 1800 h) and dark cycle was controlled manually (Supplementary Figure 1). During the baseline and recovery periods the cows experienced ambient conditions where temperature ranged from 3 to 23.4 °C (mean 10.4 °C) and relative humidity ranged from 43.7 to ...
Sheep urine affects soil solution nutrient composition and roots: differences between field and sward box soils and the effects of synthetic and natural sh... Urea-N in sheep urine returned to soil is an important component in the N-cycle of extensively managed grassland soils but relatively litt...
Distribution of Cycle threshold (Cq) values for the candidate reference genes (n = 29 samples) obtained by qPCR. Data of the three replicates per sample were averaged and those of the two thermal treatments were pooled for each gene. Boxes show the range of Cq values within each gene; ...

an initial denaturation at 95 °C for 15 min, followed by 10 touchdown cycles of 95 °C for 10 s and 61–57 °C for 1 min (with a 0.6 °C decrease per cycle), and finally 25 cycles of 95 °C for 20 s and 57 °C for 1 min for annealing. The primers for the KASP assays...
