The effect of feeding dairy heifers diets with and without supplemental phosphorus on growth, reproductive efficiency, health, and lactation performance.
The phosphorus requirements for dairy heifers (0.20-0.35%) and endogenous concentrations (0.20-35%) of P in feeds fed to dairy heifers are similar, suggesting that the need for supplemental P in dairy heifer diets may be minimal. Because long-term P feeding studies on dairy heifers are unavailable, 183 Holstein heifers and 182 backcross Holstein × Jersey heifers were offered diets with (SP=0.40...
متن کاملOptimising reproductive performance of beef cows and replacement heifers.
A reproductively efficient beef cow herd is fundamental to meeting the protein and specifically, red meat demand of an ever increasing global population. However, attaining a high level of reproductive efficiency is underpinned by producers being cognisant of and achieving many key targets throughout the production cycle and requires significant technical competency. The lifetime productivity o...

The hypothalamuspituitary-testis axis was assessed using the gonadotrophin-releasing hormone (GnRH) test. All participants also received an injection of human chorionic gonadotrophin (hCG) and serum testosterone was determined before the hCG injection and on the third day afterwards. Conventional ka...
متن کاملEffect of restriction of energy during lactation on body condition, energy metabolism, endocrine changes and reproductive performance in primiparous sows.
Seventeen Landrace X Large White primiparous sows that farrowed in August 1982 were fed ad libitum (AL, n = 8) or their intakes were restricted (R, n = 9) during lactation. Litter sizes were equalized after farrowing and pigs were not allowed creep feed. Pigs were weaned 23.8 +/- .4 d postpartum. On d 6, 12 and 20 postpartum, all sows were fasted for 16 h and blood samples were collected prior ...
متن کاملTopic 4.7 Contaminant-induced endocrine and reproductive alterations in reptiles*
Many chemicals introduced into the environment by humans adversely affect embryonic development and the functioning of the vertebrate reproductive system. It has been hypothesized that many developmental alterations are due to the endocrine-disruptive effects of various environmental contaminants. The endocrine system exhibits an organizational effect on the developing embryo, altering gene exp...
