Abstract
Nutrition and suckling are largely recognised as the most important factors affecting the postpartum period and consequently the reproductive efficiency of beef cattle. The aim of this study was to evaluate the effects of body condition score (BCS) and suckling restriction with and without the presence of the calf on milk production, reproductive efficiency and calf performance. Sixty-three crossbred (Angus × Hereford) multiparous cows were managed to maintain different BCS at calving and thereafter (low vs moderate; L, n = 31 and M, n = 32). Within each group of BCS (L and M) at week 9 postpartum (66 ± 0.88 days postpartum) cows were assigned to three suckling treatments (ST): (i) suckling ad libitum (S, n = 20); (ii) calves fitted with nose plates during 14 days remaining with their dams (NP, n = 22); and (iii) calves were completely removed from their dams for 14 days, and thereafter returned (CR, n = 21). Milk production was assessed by milking procedure at Day 65 (the day before onset of ST) and every 20?22 days until the end of the experiment. Cows were bled via jugular venipuncture every 28 days from Day ?98 (Day 0 = calving) until Day 66. From Day 66 cows were bled every 7 days until the end of the mating period (Day 128). Concentrations of progesterone, non-esterified fatty acids and ?-hydroxybutyrate acid and insulin were measured. Presence of corpus luteum (CL) was recorded and maximum follicle diameter was measured in all cows from the onset of the ST (Day 66) and during the following 4 weeks (until Day 94) in a weekly frequency. At Day 94, more cows (P < 0.001) in NP and in CR had CL compared with S cows (68, 57 and 21% for NP, CR and S, respectively). At that time, more cows in M-BCS presented CL than cows in L-BCS (77 vs 25; P < 0.0001). Within M-BCS, there were no differences in milk production between ST groups, while L-BCS cows with NP or CR produced less milk than S cows. Calf liveweight at weaning was 159.3 ± 3.1, 150.1 ± 2.9 and 147.0 ± 3.1 kg for S, NP and CR, respectively (P < 0.001). Suckling restriction with and without the presence of the calf had similar effects on reproductive performance, milk production and calf growth, while BCS interacted with ST to influence milk production. These results indicate that temporary suckling restriction could be an excellent management tool to increase reproductive performance of cows in moderate condition. MenosAbstract

En los últimos tiempos nos hemos acostumbrado a leer cómo algunas prácticas agrícolas que se aplican en nuestro país afectan al ambiente, a las personas, a la biodiversidad, o a las tres cosas al mismo tiempo. El trabajo .Disminución de la calidad del suelo a través de 13 años de producción agrícola?, publicado en la revista Nutrient Cycling in Agroecosystems por los investigadores del Instituto Nacional de Investigaciones Agropecuarias (INIA) Andrés Beretta, Osvaldo Pérez y Leonidas Carrasco, muestra que las prácticas agrícolas en Uruguay tienen efectos adversos también en el propio suelo y que podrían afectar la sostenibilidad de la propia producción. En el artículo los investigadores hacen público el estudio que hicieron en muestras de suelo de distintas partes del país que fueron remitidas al INIA La Estanzuela, ubicado en el departamento de Colonia, entre 2002 y 2014. En las muestras los científicos analizaron el pH (con que se mide la acidez o alcalinidad), los iones de calcio (Ca), magnesio (Mg), potasio (K) y sodio (Na), y el carbono orgánico del suelo (SOC). |
