Abstract:
The relationships between ovulation rate and nutrition remain confused, probably because of uncontrolled variation in experimental conditions. To help resolve the problem, we analyzed data from 20 experiments conducted between 2002 and 2016, in Uruguay with grazing ewes. All experiments were carried out by a single laboratory under comparable conditions of experimental design and measured variables. The studies used a total of 3?720 ewes, of purebred Corriedale, Polwarth, or East Friesian x Polwarth genotypes. In all experiments, a control group grazed native pastures and extra nutrition was provided to the treatment groups using either improved pastures or supplements. Ovulation rate was measured by counting corpora lutea using laparoscopy or rectal ultrasound or by counting foetuses at ultrasound on day 45 of gestation. For statistical analysis, data were grouped according to nutritional treatment (control or supplemented) and, within these groups, type of supplement to provide energy or protein (protected or not from rumen degradation). Across all experiments, 92?99% of the ewes ovulated and the effects of diet, length of supplementation, and initial live weight and genotype are reported. Within diets, ovulation was most affected by overall energy intake during supplementation (P?MenosAbstract:

La agricultura de precisión involucra un conjunto de estrategias de manejo orientadas hacia un uso más eficiente de los recursos y por tanto contribuye a una intensificación sostenible. Como forma de aportar al conocimiento y perspectivas de esta temática, INIA realizó una encuesta donde releva y analiza el estado de
situación y potencialidades de esta estrategia de manejo en los sistemas agrícolas del Uruguay.
"La agricultura d de precisión es una estrategia de manejo que reúne procesos y analiza datos individuales, temporales y espaciales, que combinados con otra información del sitio apoya la toma de decisiones de manejo de acuerdo a la variabilidad estimada, buscando mejorar la eficiencia de uso de los recursos, la productividad, la calidad, la rentabilidad y últimamente la sostenibilidad de la producción agrícola.
