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. |

ABSTRACT.- Background and aims: Since 1750, the species-rich grasslands native to the Río de la Plata basin in southern South America have sustained low-input livestock production. Typically, these grasslands have low herbage phosphorus (P) concentration, and P deficiency in livestock is not rare. Worldwide, P fertilization is used to increase the productivity and nutritive value of grasslands, but it is unknown whether the Río de la Plata grasslands are limited by P availability. -- Methods: We quantified the response of aboveground net primary productivity (ANPP) to P supply in a meta-analysis of 39 trials carried out between 1968 and 2016 comprising 285 independent comparisons (cases) between unfertilized controls and P-fertilized treatments. -- Results: The ANPP of unfertilized controls ranged from 400 to 17,500 kg dry matter (DM) ha-1 y-1. In 74% of cases, P fertilization did not increase ANPP. The average response was therefore low, at 399 kg DM ha-1 (relative effect + 15%), and largely unrelated to ANPP, vegetation, or soil characteristics. Conversely, in 59% of cases herbage P concentration did increase, particularly at high fertilization rates (average 0.43 mg P g DM-1; relative effect + 36%). -- Conclusions: Despite low herbage P concentration, the current ANPP of Río de la Plata grasslands seems little limited by P supply. Luxury consumption was common in response to P fertilization. Prevailing low herbage nitrogen-to-phosphorus ratios -below 11:1 in 65% of unfertilized controls- suggest nitrogen may be limiting ANPP. In this legume-scarce ecosystem, P fertilization is unlikely to boost productivity and may pose an environmental risk. © 2024 Springer Nature MenosABSTRACT.- Background and aims: Since 1750, the species-rich grasslands native to the Río de la Plata basin in southern South America have sustained low-input livestock production.
