ABSTRACT - This study was conducted to evaluate the interaction between dose of estradiol cypionate (ECP) and ovarian status in beef cows on which different weaning/suckling regimens were imposed before fixed-time artificial insemination (FTAI). A total of 8070 estrous cycling and anestrous cows were subjected to three experiments, when calves were weaned early (Experiment 1), anti-suckling nose plates were applied for 9 or 10 days (Experiment 2), or there was continued suckling (Experiment 3). The cows were administered an estradiol/progesterone?based treatment regimen for FTAI and were treated with 0.5 or 1.0 mg of ECP im at the time of progesterone intravaginal device removal. Artificial insemination was performed from 46 to 56 h after the time of ECP treatment. Pregnancy per artificial insemination (P/AI) was affected by dose of ECP differentially in early-weaned and suckled cows. Whereas P/AI percentage was greater in early-weaned cows treated with 0.5 than 1.0 mg ECP (P < 0.05), P/AI percentage was greater for suckled cows treated with 1.0 than 0.5 mg ECP (P < 0.05). Although there were greater P/AI percentages in estrous cycling than anestrous cows (P < 0.05) when there was nose plate weaning and continuation of suckling, there was no difference between estrous cycling and anestrous cows (P = NS) when there was early weaning. Overall results indicate ECP administration affects fertility in a dose-dependent manner, suggesting an interaction between suckling and estrous cycling effects. As more critical the condition was (i.e., suckling anestrous cows), larger dose of estradiol was required. © 2021 MenosABSTRACT - This study was conducted to evaluate the interaction between dose of estradiol cypionate (ECP) and ovarian status in beef cows on which different weaning/suckling regimens were imposed before fixed-time artificial insemination (FTAI).

ABSTRACT.
Lotus uliginosus (greater lotus, GL) and L. corniculatus (birdsfoot trefoil, BT) are species markedly different in their genetics, morphology and environmental adaptation. We evaluated the hybrids and parental species under differential conditions: in vitro culture, growth chamber and open field environments. The experimental evaluation included biochemical, physiological, developmental and productive parameters. Parental species exhibited significant differences in root growth under different osmotic potentials generated by polyethylene glycol, and hybrids exhibited variability in their response compared with their parents. Plants grown in pots and subjected to drought exhibited differences in biochemical parameters. Proline accumulation and oxidative damage measured by lipid peroxidation were higher in birdsfoot trefoil than any other genotype, and the lowest values were observed in greater lotus. The total phenolic content in shoot ranged from 147 to 279mg gallic acid equivalents 100g-1 dry mater. With regard to antioxidant capacity estimated by 2,2-diphenyl-1-picrylhydrazyl, greater lotus had the highest value and birdsfoot trefoil the lowest, at almost one-third, whereas hybrids had intermediate values. Under stress conditions, water-use efficiency showed significant differences between both parental species. In the field, under either irrigation or drought, the dry matter accumulated by the hybrids was higher than that of the parents. Hybrids express recombination of features, making them an interesting material to continue evaluation.
