El objetivo de este estudio fue evaluar el impacto de la carga animal y la alimentación diferencial de los terneros o creep feeding (CF) sobre su tasa de crecimiento y la eficiencia reproductiva de las madres. Sesenta piezas de cría Hereford fueron asignadas a un diseño que estudió el efecto de la carga y el creep (n = 15/grupo): 1) Carga baja (1,1 UG/ha); 2) Carga baja con CF; 3) Carga alta (1,7 UG/ha); 4) Carga alta con CF. Los animales pastorearon en forma continua en campo natural reservado (Ornitophus pinnatus) con una disponibilidad de 2100 kg MS/ha. Los terneros recibieron una ración comercial con 21% de proteína cruda. Se realizó detección de celo diario, peso y condición corporal cada 14 días, comportamiento en pastoreo y producción de leche cada 3 semanas. Los terneros del grupo carga baja con CF tuvieron mayores pesos al destete (P<0,01). El consumo de ración disminuyó las horas destinadas a pastoreo pero no el consumo de leche. Las vacas de los grupos CF aumentaron de peso y produjeron más leche, por lo que no mejoró su eficiencia reproductiva. Las vacas de carga alta no vieron deprimida su performance reproductiva a pesar de que perdieron peso. Concluimos que el CF tuvo un impacto positivo en peso al destete sin afectar el desempeño reproductivo de las madres. |

ABSTRACT.
Brown rot caused by the fungus Monilinia fructicola is the most important disease in peach production areas of Brazil. The increased concern with the environment, consumers and workers' health, emphasizes control strategies other than fungicide applications. Among them genetic resistance is the most efficient. However, availability of resistant genotypes is still limited. Thus the main objective of this work was to seek sources of brown rot resistance, as well as to study the segregation, estimate the heritability and verify the possible existence of maternal effects. Heritability of brown rot resistance was investigated in peach fruits of several genotypes from the Embrapa peach breeding program. Sixteen progenies and 20 parents were evaluated. Disinfested fruits were wounded with a microsyringe and inoculated by deposition of a 10 ?L drop of a 2.5×104 spores mL?1 of M. fructicola. The fungus inoculum was obtained from a culture originated from peach mummies from four different sites. After inoculation, the fruits were incubated under controlled conditions for 72 h, before evaluation of lesion size and sporulation. High phenotypic variability and transgressive segregation were observed for brown rot resistance in fruits. Several genotypes showed similar resistance as 'Bolinha', the standard Brazilian cultivar for resistance. The heritability of brown rot resistance in fruits (diameter of the lesion and sporulation), was medium. Parental selection based on phenotype, enables a medium genetic advance for brown rot resistance. The selections Conserva 947 and Conserva 1600 were the parents with higher brown rot resistance (similar to 'Bolinha'), with the potential of passing this trait to their offspring.
