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.
There are opportunities to improve livestock family farms (LFFs) sustainability in Uruguay by using the co-innovation approach to change management practices and incorporate technologies. To harness these opportunities, between 2012 and 2015, a research project was implemented in Eastern Uruguay, where three simultaneous processes occurred at three levels: farm, region, and research team. At farm level, the work was carried out in seven LFF as case studies following three steps: (i) characterization and diagnosis; (ii) redesign; and (iii) implementation, monitoring, and evaluation. At the regional level, a participatory approach to planning, monitoring, and evaluating the project?s progress with regional stakeholders was adopted. At the team level, a Participatory Action Research approach was used. Consensus on the objectives and methods allowed for combined knowledge to solve practice-oriented problems. The 3-year project demonstrated the effectiveness in improving LFF sustainability, opened a learning space with stakeholders, and utilized a co-innovation model to improve rural development outcomes.
