Animal Reproduction Science, 2011
During the last three decades, there has been remarkable progress in many aspects of ovarian biology due to advances in real-time ultrasonography, which permits non-invasive, repeated monitoring of ovarian structures in conscious and non-anaesthetised animals.

The oestrous cycle in pigs spans a period of 18-24 days. It consists of a follicular phase of 5-7 days and a luteal phase of 13-15 days. During the follicular phase, small antral follicles develop into large, pre-ovulatory follicles. Being a polytocous species, the pig may ovulate from 15 to 30 follicles, depending on age, nutritional status and other ...

Reproductive cycle of the elephant
Animal Reproduction Science, 2011The combination of a few factors, including poor captive reproduction, secession of importation from the wild and advances in hormone detection and ultrasonography, has contributed to the current knowledge on the elephant reproductive cycle. Several reproductive features in elephants differ markedly from other mammals.

Horses are long-day breeders. During the breeding season, cycle length is about 22 days with 5-7 days of oestrus. Gonadotroph cells are localized in the pars distalis as well the pars tuberalis of the pituitary and heterogeneity in the pattern of LH and FSH storage within the gonadotroph population is considered the basis for the differential ...

Reproductive cycles of buffalo
Animal Reproduction Science, 2011The domestic water buffalo (Bubalus bubalis) has an important role in the agricultural economy of many developing countries in Asia, providing milk, meat and draught power. It is also used in some Mediterranean and Latin American countries as a source of milk and meat for specialized markets.

The cervids are a complex assemblage of taxa showing extreme diversity in morphology, physiology, ecology and geographical distribution. Reproductive strategies adopted by various species are also diverse, and include a range from highly seasonal to completely aseasonal birth patterns.

Cell reproduction cycle of mycoplasma
Biochimie, 1999The cell reproduction cycle of parasitic wall-free bacteria, mycoplasma, is reviewed. DNA replication of Mycoplasma capricolum starts at a fixed site neighboring the dnaA gene and proceeds to both directions after a short arrest in one direction. The initiation frequency fits to the slow speed of replication fork and DNA content is set constant.

THE ANNUAL REPRODUCTIVE CYCLE IN MALLARDS
Journal of Steroid Biochemistry, 1983In wild mallard drakes plasma FSH and LH levels were elevated at the height of the breeding season in spring, decreased towards the end of the reproductive phase and were low during the time of photorefractoriness in summer, when the testes were regressed. In contrast plasma prolactin concentrations increased only towards the end of the breeding season

The reproductive cycle of the gelada baboon
Animal Behaviour, 1974Changes in the visual appearance of the sexual skins of female Theropithecus gelada associated with different stages of the reproductive cycle and with age are analysed using data from a large sample of females in the wild. Changes associated with the oestrous cycle and with pregnancy and birth are confirmed by a more detailed study of particular ...
