Abstract

On the day of induced estrus, jugular vein blood samples were collected from healthy repeat breeder cattle (n=45) for the estimation of haemoglobin, glucose, cholesterol and total protein, followed by pregnancy diagnosis on day 45 post-insemination. There was no difference (p<0.05) in haemoglobin, plasma cholesterol and plasma total protein in animals showing weak, intermediate or intense estrus, however, plasma glucose was high (p<0.05) in animals exhibiting intense estrus compared to their counterparts exhibiting intermediate estrus. Between pregnant and non-pregnant counterparts, plasma total protein was high (p<0.05) on the day of induced estrus in the former, whereas other blood/plasma parameters were similar (p>0.05). In brief, plasma ...

Abstract

Repeat breeder cattle (n=45) were synchronized using intravaginal progestational device (TRIU-B) based Co-Synch protocol. On day 6 post artificial insemination (AI), all the animals were administered (i.m.) either 10 µg GnRH analogue, (n=15), 1500 IU hCG (n=15) or normal saline (n=15). Pregnancy...

Abstract

The female yaks (n=52) were detected in estrus by parading vasectomized bull between 8-9 am (morning) and between 3-4 pm (evening). A group of females (n=18) detected in estrus in morning were inseminated twice on the same day between 9-10 am and between 4-5 pm. The remaining females (n=13)...

Abstract

Semen was collected from seven exotic stallions for the evaluation of seminal characteristics and freezability of semen. The appearance of fresh semen was milky-white to creamy and consistency of gel-free semen was variably thick. The total volume of semen, gel-free semen and gel in semen was...

Abstract

Estrus mucus (EM) and blood (serum) was collected from 40 apparently normal cattle (Normal breeder, NB=20; Repeat breeder, RB=20) at the time of insemination for glucose, minerals, alkaline phosphatase (ALP), lactic dehydrogenase (LDH) and α-amylase concentration. In NB cattle, serum glucose and...

Abstract

Fertility is declining in domestic animals across the world. The reduction in fertility could be attributed to male, female and managemental factors. Although artificial insemination (AI) using frozen semen emerged 50 years back, fertility rate with AI technology is less and unpredictable. In AI...
