Estradiol administration and reproductive performance in rats

Journal of Experimental Zoology, 1968
AbstractEstradiol in doses of 2 and 4 micrograms increased uterine triphenyltetrazolium (TTC) metabolism at day of breeding when administered for two days prior to breeding. Estradiol as administered in these experiments resulted in decreased uterine TTC metabolism at day 4 and 8 of gestation when compared to the metabolism of untreated females.Two ...

Epidemiology of reproductive performance in dairy cows

Animal Reproduction Science, 2000
The objectives of this presentation are to review results of our previous and on-going research with respect to the risk factors and consequences of poor reproductive performance in dairy cows, and to develop an economic framework to optimize decisions related to dairy cow reproductive performance. To make profitable breeding and replacement decisions,

Reproductive history of cane rat: a review of the reproduction and reproductive performance

2018

Welfare Index and Reproductive Performance in the Sow

Reproduction in Domestic Animals, 2006
ContentsTo study the relationship between on‐farm welfare and reproductive performance in the sow, the TGI 35L Animal Needs Index was modified for use in Finnish pig production. The modified index had a maximal total score of 100. It was comprised of six categories: ‘locomotion’ (maximal score 21 for dry sows and 11 for lactating sows), ‘social ...
