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 g...

In the infantile animal the reproductive organs gradually develop but do not begin to function as organs of reproduction until the age of puberty, although their internal secretions begin before this time. In the female the cause for their functioning lies outside the ovary itself, for immature ovaries transplanted into adults begin to function immediately, whereas adult ovaries transplanted in...

Rudolf Cardinal, 22/24 Nov 1998 Implantation and the decidual response • Implantation in humans and some other species is invasive – the uterine surface epithelium is breached and the underlying stroma is invaded. (In yet other species, the epithelium remains intact with the fetal and maternal epithelia in close contact.) • The blastocyst makes a signal (unknown) which induces a stromal respons...

As the pioneering research cited in the previous chapter demonstrates, the kinds and concentrations of nutrients affect the development of the asexual apparatus of watermolds. The beginning efforts to study the relationship between nutrition and morphogenesis, not only of the sporangia but of the sexual apparatus as well, were severely hampered by lack of attention to precise chemical definitio...

cass traits as barrows fed the C-SBM diet (P > 0.10). In Exp. 2, 60 barrows (initial and final BW of 74.6 and 104.5 kg, respectively) were used to estimate the dTrp requirement. The levels of dTrp used in Exp. 2 were 0.06, 0.08, 0.10, 0.12, or 0.14%. Response variables were growth performance, PUN concentrations, carcass traits, and pork quality. The dTrp requirement was estimated to be 0.102%....
