Rabbit is the third most commonly used animal model in different fields of scientific research, such as reproductive biology, fertility and embryo transfer studies, and immunology. This animal species, often used in antibodies production, has minority of scientific records about the immunological status of its reproductive organs. The aim of this study was to find histological and immunological...

Reproductive biology of three important small indigenous fish species mola (Amblypharyngodon mola), punti (Puntius sophore) and chela (Chela cachius) was studied for 12 months from January to December, 1999 in the Department of Fisheries Management, Bangladesh Agricultural University, Mymensingh. Gonadosomatic index (GSI) and ova diameter were analysed to determine their reproductive cycle. Thr...

The pampas deer (Ozotoceros bezoarticus) is a South American grazing deer which is in extreme danger of extinction. Very little is known about the biology of the pampas deer. Moreover, most information has not been published in peer-reviewed scientific journals, and is only available in local publications, theses, etc. Therefore, our aim was to update and summarize the available information reg...

We report here the toxic effects of chlorpyrifos, a broad-spectrum organophosphorous insecticide, on female reproductive function in rat model. We observed significant alterations in the rhythmicity and phasic cellular characteristics of estrous cycle with a concomitant increase in diestrus index in chlorpyrifos treated female rats in a dosedependent manner (5.4 and 8.1 mg/Kg.b.wt./day) compare...

The goal of any breeding operation is to maximize reproductive efficiency and minimize the cost of producing live offspring. The reproductive performance of broodmares can be assessed by determining pregnancy and foaling rates for a season or, preferably, for each cycle. Mean pregnancy rates per cycle are 50% to 60% under current management conditions. However, the rates vary widely depending o...
