Endocrine Profiles of Oestrous Cycle in Buffalo: A Meta-analysis
A meta-analysis was conducted to summarize the results of studies which have described the profiles of hormones during the oestrous cycle in buffalo using a fixed effect model and a random effect model. Plasma progesterone concentrations were lowest (0.30±0.06 ng/ml) during the peri-oestrous phase and increased (p = 0.067) through the early luteal phase to a maximum concentration (1.94±0.03 ng/...
متن کاملControl of the mare's oestrous cycle by prostaglandins.
Several authors have recently demonstrated the luteolytic action of exogenous prostaglandin F2\g=a\(PGF2\g=a\)in various laboratory and domestic animals and there is now ample evidence that PGF2\g=a\is the uterine luteolytic hormone which terminates the life of the CL in many species (McCracken, 1972; McCracken, Carlson, Glew, Goding, Baird, Gr\l=e'\en & Samuelsson, 1972). In cattle, Rowson, Te...
متن کاملThe Oestrous Cycle and Its Control in Livestock
In nature it is the general rule that animals breed once annually and parturition occurs in the spring, the time most favourable to the progeny in that they grow up during the period of increasing light and warmth and also at the time when food for the mother is most abundant and adequate lactation is ensured. Under the conditions of feeding and housing provided by domestication the breeding se...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولFollicular, endocrine and behavioural dynamics of the Indian rhinoceros (Rhinoceros unicornis) oestrous cycle.
Longitudinal ultrasound, behaviour and endocrine evaluations were conducted, over 14 to 18 months, in two young female Indian rhinoceroses (Rhinoceros unicornis) to characterize the oestrous cycle. Both females showed the same pattern of follicular development producing a large follicle (10-12 cm diameter) on one of the ovaries that persisted for 8.5 +/- 4.68 days before spontaneously ovulating...
