“…BCS at estrus was positively correlated with the conception rate [10]. Campanile et al [11] did not find such relationship between BCS at breeding and pregnancy outcome. They interpreted the lack of an apparent relationship as suggesting that the effects of nutrition and metabolic status on fertility in female buffaloes can be influenced by photoperiod.…”

Abstract. The diameter of the preovulatory follicle (POF) and its effects on subsequent corpus luteum (CL) size and conception were studied in 38 lactating indigenous cycling buffaloes in the Mymensingh district of Bangladesh. Body condition score (BCS) at estrus was estimated for the buffaloes. The buffaloes were synchronized with two injections of a synthetic analogue of PGF2 α administered 11 days apart. Transrectal ultrasonography was carried out at estrus and on days 5, 9, 12 and 16 post ovulation to determine the POF and successive CL size. Pregnancy was confirmed by ultrasound examination on day 40-45 post ovulation. Twenty one (55.3%) buffaloes were diagnosed as pregnant. The conception rates of thin (BCS ≤2.0), good (BCS 2.5-3.5) and fat (BCS >3.5) buffaloes were 7.7, 88.2 and 62.5% (χ 2 = 19.54; P<0.05), respectively. The mean diameter of the POF at estrus was larger (P<0.01) in buffaloes that ultimately were diagnosed as pregnant compared with their nonpregnant counterparts (13.7 ± 0.3 vs. 11.2 ± 0.5 mm, respectively). The conception rates of buffaloes having small (9 to ≤ 12 mm), medium (>12 to ≤14 mm) and large (>14 to 16 mm) POFs at estrus were 9.1, 70.0 and 85.7% (χ 2 = 13.87, P<0.01), respectively. On day 5 post ovulation, CL size was positively correlated (CL: r=.74, P<0.01) with POF diameter. Retrospective analysis revealed that on day 5 post ovulation, the pregnant buffaloes had higher (P<0.01) post ovulation CL sizes than their nonpregnant counterparts (15.6 vs. 11.8 mm). Similarly, on day 9 post ovulation, the difference in CL size (14.3 vs. 13.6 mm) between pregnant and nonpregnant buffaloes was significant (P<0.05). In conclusion, the diameter of the POF in buffaloes has a positive impact on the size of the post ovulation CL and conception. Key words: Corpus luteum (CL), Preovulatory follicle (POF), Water buffalo (J. Reprod. Dev. 58: [219][220][221][222] 2012) T he preovulatory follicle (POF) is the prime structure behind the endocrinology of estrus in buffaloes that produces substantial amounts of estradiol. A positive correlation exists between the diameter of the POF and plasma estradiol concentration and the subsequent pregnancy rate in cattle [1,2]. It is speculated that the POF diameter is important for the subsequent development of the corpus luteum (CL) and hence conception in buffaloes. A larger POF may generate a larger CL that secretes more progesterone and thereby have a positive effect on pregnancy recognition and pregnancy rates in cattle [3,4]. On the other hand, others have reported absence of correlation [5] or negative correlation [6] between POF diameter and pregnancy outcome. For successful pregnancy, the preovulatory follicle and subsequent luteal size may be important in the indigenous buffaloes. But reports on such work in indigenous buffalo of Bangladesh are not available in the literature. So, it is important to investigate the relationship of POF size and subsequent CL size and pregnancy rate. Use of ultrasonic imaging of ovarian follicular and luteal developme...

In this paper, an account of various aspects related to buffalo reproduction are given. Fundamental concepts of the reproductive physiology as well as manipulation of the reproductive function will be presented. This will include an overview of the most recent developments of the oestrous cycle and the ovulation control, new strategies of reproductive management for the improvement of genetic gain and the application of newly developed reproductive technologies, such as in vitro embryo production, embryo and sperm sexing and cloning.

“…Such data was also partially proved for domestic animals fed with diet rich with degradable proteins that generate a high level of urea in maternal blood [20,21]. However, a maternal toxicity can not be taken into consideration as a leading mechanism that explains interleukin expression, since the phenomenon was observed mostly in fetuses obtained from mothers without gross and histological signs of adverse effects of the examined xenobiotics [10,11].…”

Unusual expression of interleukin-1alpha, -1beta and -6 was previously found in the epiphyseal cartilage of rat fetuses prenatally exposed to various non-steroidal anti-inflammatory drugs (NSAID, i.e., ibuprofen, piroxicam, tolmetin) and selective cyclooxygenase-2 inhibitor (DFU). The aim of the present study was to evaluate the role of placenta in such phenomenon. Morphology of the organ, thickness of basal and labyrinth layer, immunoexpression of COX isoenzymes were examined, and confronted with maternal biochemical data and fetal developmental parameters. Higher maternal urea level, as well as lower placental weight and labyrinth thickness were found in the group of fetuses who revealed expression of genes coded the selected interleukins, when compared with the xenobiotic-exposed pups without the selected genes expression and untreated control. A significant correlation between placental weight and maternal total protein or urea level was revealed. Histological changes like inflammatory infiltration and calcification were observed sporadically. Location and intensity of COX-1 staining was similar in all cases. However, more intense COX-2 staining for majority of cells of the basal zone and in dispersed giant cells of the labyrinth was found in inflamed organs. It could be concluded that abnormal expression of the selected interleukins is associated with low placental weight and decrease of its thickness, especially labyrinth zone, as well as with high maternal urea level.
