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:

CONCLUSIONES:
Es posible en sistemas agrícolas pastorear los CdeS sin deterioro en el corto/mediano plazo de las propiedades físicas del suelo y la productividad del cultivo de soja. El pastoreo con cargas moderadas (3-4 UG/ha) genera producciones de carne del orden de los 250350 kg de PV/ha en un corto período de tiempo.
En sistemas agrícola-ganaderos es importante puntualizar que, un aprovechamiento de pasto durante el invierno siempre repercute en forma positiva en el sistema. Se levanta una de las restricciones que es la capacidad de carga en el invierno. Podemos entrar con mayor carga en la primavera temprana, cosechar mayor cantidad de pasto y aumentar así la producción de carne del sistema. |
