Effect of Multiple Stresses (Thermal, Nutritional, and Walking Stress) on the Reproductive Performance of Malpura Ewes
A study was conducted to assess the effect of multiple stresses (thermal, nutritional, and walking stress) on the reproductive performance of Malpura ewes. The study was conducted for a period of 35 days covering two estrous cycles during summer season (April-May). The ewes were randomly allocated into two groups of twelve animals each namely, GI (n=12; Control), and GII (n=1 2; Multiple stress...
متن کاملThe Impact of Spatial Structure on Viral Genomic Diversity Generated during Adaptation to Thermal Stress
BACKGROUND Most clinical and natural microbial communities live and evolve in spatially structured environments. When changes in environmental conditions trigger evolutionary responses, spatial structure can impact the types of adaptive response and the extent to which they spread. In particular, localized competition in a spatial landscape can lead to the emergence of a larger number of differ...
متن کاملVesiculation of sickle erythrocytes during thermal stress.
Since it is not known why sickle RBCs tend to undergo microvesiculation, we have investigated their susceptibility to thermal stress. While normal RBCs start to vesiculate at 49.0 +/- 0 degrees C (n = 14), sickle RBCs begin to vesiculate at 47.9 +/- 0.5 degrees C, with a range of 46.5 to 48.5 degrees C (n = 14). This abnormality is reproduced by treating normal RBCs with phenazine methosulfate ...
متن کاملEffect of Metabolic Stress on Ovarian Activity and Reproductive Performance of Dairy Cattle: A Review
Reproductive efficiency in dairy cattle has been decreased over the last 5 decades despite significant gains in genetic selection, improved reproductive technologies and nutritional care. In high-yielding dairy cattle, the negative energy balance (NEB) during the first week post-partum adversely affects ovarian activity, mainly follicle growth and steroidogenesis. Circulating levels of non-este...
متن کاملStudy of Reproductive Performance of Crossbred Ewes Treated with GnRH and PMSG during Breeding Season
Reproductive performance was evaluated in non-lactating crossbred ewes to which were administered the exogenous GnRH and PMSG. The ewes were randomly allocated in three treatment groups (n=40).After accurate detection of estrus and 2 hours prior to mating, 2.5 mL of distilled water and 2.5 mL of GnRH were injected intramuscular to each ewe of the first (control) and second group, respectively. ...
