Long-acting GnRH agonists have been used both for canine estrus induction and prevention. The objective of the study was to investigate the use of a deslorelin implant as a long-term and reversible contraceptive in prepubertal bitches with special regard to the time of epiphyseal closure. Thirteen healthy, crossbreed, medium-sized prepubertal female dogs were used in this study. An implant cont...

In the mammalian forebrain, most neurons originate from proliferating cells in the ventricular zone lining the lateral ventricles, including a discrete area of the subventricular zone in which neurogenesis continues into adulthood. The majority of the cells generated in the anterior portion of the subventricular zone (SVZa) are neuronal precursors with progeny that migrate to the olfactory bulb...

Characteristics of estrus, mating, and pregnancy were studied in captive fennec foxes. The monestrous cycles had mean intervals of 9.9 (!1.2) months, whether or not pups survived to weaning. Proestrus, judged by vulval swelling, began 6.5 (!0.7) days before estrus and was not accompanied by sanguineous discharge. Percentage cornified epithelial cells in vaginal smears increased at the time of e...

Background: Acute-phase proteins (APPs) may be increased due to different stresses during estrus phase in farm animals. Aims: Determining changes of APPs at different phases of non-synchronized estrous cycle group (NSEG), and Ovsynch-synchronized estrous cycle group (SEG) in Holstein cows. Methods: Twelve non-pregnant clinically and paraclinicaly healthy Holstein cows with a body condition scor...

the purpose of this research was the study of reproductive performance in postpartum dairy cows with different parities. twenty holstein dairy cows were assigned into two equal primiparous and multiparous groups. body weight and body condition score (based on 1-5 scoring) were measured every other week, starting from two weeks before calving till pregnancy confirmation. daily milk yield was als...

The goal of this experiment was to compare the effectiveness three popular synchronization protocols, viz. ovsynch, double prostaglandin (PGF2? /PG) injections, and MAP (Medroxyprogesterone acetate) sponges, in anestrous goats. Twenty one non pregnant multiparous goats with an average body condition score (BCS = 2.5) were selected. After last PG injection, all exposed fertile bucks. They observ...

Background: Early detection of pregnancy can perk up the reproductive competence dairy animals and decreasing interval between two successive AI. Several methods diagnosis both direct indirect are being practiced; but to date, none these technologies qualifies as ideal method due its limitation. The present study was designed learn about changes hormonal blood metabolites during early bovine pr...

Received: Revised: Accepted: April 04, 2013 October 17, 2013 January 25, 2014 The present study was conducted to determine the macro mineral profile and biomarkers of oxidative stress in Cholistani cattle kept at a public farm and various villages in district Bahawalpur. For this purpose 90 blood samples were collected each from estrual, anestrous and repeat breeding cattle having different age...

Aim: To compare the amylase activity in the cervical mucus and serum during estrus in normal and repeat breeder cattle and find out importance in fertility. Materials and methods: Twenty cyclic crossbred cattle were divided into two groups: normal (n =10) and repeat breeder (n =10). Animals exhibiting spontaneous estrus, were artificially inseminated (AI) twice, as per AM-PM schedule along with...
