ABSTRACT
The objective of the present work was to investigate the effects of two levels of crude protein (CP) provided to mature dams during late gestation on subsequent heifer’s growth postweaning and reproductive performance. At 121 d prepartum, 68 multiparous Angus cows were blocked by BW and expected calving date and
randomly assigned to low protein (LP, 6% CP) or high protein (HP, 12% CP) at 12 pens per treatment. Following calving, all cow/calf pairs were housed together until weaning, then female progeny were removed and maintained on pasture as a single group. At puberty (P = 0.01) and pregnancy determination (P = 0.05) the HP heifers were heavier than LP heifers. The LM area was greater at 20 mo of age in HP compared to LP heifers (P = 0.01). Serum IGF-1 concentration was greater in HP heifers compared to LP heifers (P = 0.05). No dam nutrition effects were found on offspring age at puberty (P = 0.98), final pregnancy rate (P = 0.28). Protein supplementation during late gestation does not affect reproductive performance of the offspring heifers but did impact their BW evolution. The use of diet with low amount of protein which the female fetus is exposed in utero can affect her subsequent development. |

The emergence of new technologies, the conservation of biodiversity and genetic resources, the environmental consequences of current agriculture practices, the impacts of climate change, the gaps in 79 adoption of key technologies and the expansion of plant pest and diseases are all examples of current challenges of the food and agriculture system that requires a scientific, policy and future-oriented, regional approach. The Cooperative Program for the Development of Agricultural Technology in the Southern Cone (PROCISUR), integrated by the National Agricultural Research Institutions (NARIs) of the Southern Cone, conducted a foresight exercise to build capabilities on this discipline and to raise awareness about the usefulness of foresight approaches to policy makers. |
