I would like to say thank you to Courtney Cochran, my lab instructor and to the UCSB Biology department for the time taken in order to ensure accurate results. Another round of thanks goes to Emile Laroche, my lab partner who aided me in data collection and procedure.

Evidently, many issues are associated with the management of feedlots and the procedures used to ingest cattle with unacceptable levels of hormones. Indicated previously, injecting high levels of rBGH into cattle can lead to the increase in IGF-1, a hormone that has been associated with an increased risk of breast, prostate and

There has been a long history of the effect of body condition on postpartum interval; however, there have been limited reports to elucidate the interaction between body condition score and follicular populations and how this affects postpartum interval. Postpartum Interval is defined as the period of sexual rest during which the reproductive system is mainly quiescent. Follicular development is minimal; the corpora lutea, although identifiable, have regressed and are non-functional. Secretions are scanty and viscous, the cervix is constricted, and the vaginal mucosa is pale (Sheldon, 2002). A major obstacle in maintaining a 12-mo calving interval for beef producers, particularly for those using Brahman females, is the long duration of the postpartum anestrous period. In order to curb this, a postpartum animal must recover from the suppressive effects of gestation and parturition on the pituitary, ovarian and endocrine systems (Browning et al., 1994). Pituitary and ovarian function in suckled beef cows may return within 4 to 5 wk after calving (McNatty, 1988; Wright et al., 1990). Nutrition is a major factor controlling the length of the postpartum acyclicity (Randel, 1990). When an animal gains or losses body condition the amount of leptin in blood is changed (Amstalden et al., 2000; Amstalden et al., 2005), due to the increase in adipocytes, thus affecting the release of GnRH; and thereby affecting oogenesis, follicular maturation and ovulation (Gentry et

This is further backed up by a study(23) conducted in women who suffered from hypothalamic amenorrhoea. That means they have no periods because of insufficient GnRH production. The levels of leptin in these patients were discovered to be abnormally low. After being given recombinant leptin mean LH concentrations and LH pulse frequency was significantly

Despite the species or facet of the industry an operation is built to cater too, one of the easiest ways to improve the efficiency of livestock is through feed and nutrient management. Feed efficiency for livestock only becomes more important as farmers are responsible for feeding a growing population. However, in order to do that is important that a manager or owner understands the digestive system of that species and factors that can aid in this system ability to absorb the maximum amount of nutrients. This paper will be focused around different aspects of the ruminant digestive tract, and more specifically two of the smaller ruminant species being sheep and goats. I will explain in detail the 6 essential nutrients and why they are crucial to have in a feed ration, what occurs in each compartment of the stomach, including breakdown of feed,
