Última Reproductive behavior of crossbred dairy cows grazing an intensive silvopastoral system under tropical dry forest conditions 45 Sierra-Montoya,E.; Barahona-Rosales,R.; Ruiz-Cortés,Z.T.. ABSTRACT It is widely accepted that selection for high milk yield in dairy cows has negatively affected their reproductive performance. After calving, dairy cows experience a nutritional imbalance due to an asynchrony in the occurrence of the lactation and dry matter intake peaks. In the tropics, this situation is exacerbated due to poor quality and/ or availability of the diet. A study was carried out to describe the nutritional and reproductive behavior of two-to-four parturition crossbred cows (Gyr (Bos indicus) x Holstein (Bos taurus)) divided in two groups according to their calving to first service interval (CFSI): Group 1: ≤50 days CFSI, n=7; Group 2: ≥50 days CFSI, n=8. Animals were grazing in an intensive silvopastoral system (ISS) based on... Tipo: Info:eu-repo/semantics/article Palavras-chave: Days open; Energy balance; Intake; Leucaena; Nutritional management.
