The effect of programmed assistance at parturition on the behaviour of the mother and its offspring in primiparous ewes under extensive rearing was evaluated. Programmed parturition assistance was defined as the manoeuvres performed immediately after the beginning of the expulsion phase to shorten it. Twenty-eight 2-year-old Corriedale primiparous ewes (body condition score (BCS): 3.4 ± 0.1; body weight (BW): 35.5 ± 0.7 kg) with a single foetus were used. Before lambing and considering BW, BCS and sire, the ewes were randomly assigned to (i) Programmed-parturition-assisted (PPA; n = 14): ewes whose lambing was programmed to be assisted or (ii) Not-assisted (NA; n = 14): ewes that were not assisted and their lambs were born through natural labour. The duration of the foetus expulsion phase, maternal behaviour score (MBS, 1-5), onset of grooming, lamb/ewe BW ratio and lamb desertion were determined in the ewes. Birth weight, Apgar test (score 0-10), O2 saturation, meconium-stained coat, latency to first bleat, success to stand and suck, were registered in the lambs. PPA ewes registered shorter duration of labour (19.2 ± 4.2 vs. 42.6 ± 7.8 min), earlier onset of grooming (1.2 ± 0.4 vs. 3.0 ± 0.6 min), higher MBS (4.5 ± 0.1 vs. 3.1 ± 0.4) and did not desert any lamb during the first 72 h from birth. The lambs born to PPA mothers registered higher O2 saturation (97.6 ± 1.0 % vs. 93.4 ± 1.3 %), bleated earlier (2.4 ± 0.5 vs. 4.6 ± 0.8 min), stood up earlier (24.1 ± 4.2 vs. 36.8 ± 8.0 min) and recorded shorter time to suck (36.5 ± 6.7 vs. 71.0 ± 12.9 min). No effect of treatment on Apgar test or meconium-stained coat was observed, but regardless of treatment, meconium-stained lambs had a higher lamb/ewe BW ratio than unstained ones. The reduction of the duration of foetal expulsion phase, through programmed parturition assistance, positively affected the vigour of the lambs as well as the maternal behaviour of primiparous ewes, which in turn would increase the chances of lamb survival and ultimately, improve the welfare of the ewe-lamb unit. © 2023 Elsevier B.V.

ABSTRACT.- Irrigated rice fields are major sources of two important greenhouse gases (GHG), methane and nitrous oxide. As an initial step towards obtaining local information, emissions of CH4 and N2O from rice paddy soil were measured by the static chamber technique in greenhouse and field experiments conducted in eastern Uruguay. In the greenhouse experiment, the effect of two flooding moments (21 and 45 days after emergence) and nitrogen fertilization (0 and 50 kg N ha-1) on gas emissions was studied. Early flooding and nitrogen fertilization tended to increase N2O emissions. In the field experiment, effect of winter soil cover crop and nitrogen fertilization (0 and 82 kg N ha-1) were tested. Higher CH4 fluxes were observed mainly during the reproductive stage of the plant in the N-fertilized treatment with ryegrass winter crop. N2O flux peaked at flushing. Results indicate that the use of cover crops might increase GHG emissions during the rice cycle. Despite differences in agronomic management practices employed in Uruguay, CH4 and N2O fluxes are within magnitudes previ-ously reported for rice fields worldwide. .-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-. RESUMEN.- Los arrozales son fuente de dos importantes gases de efecto invernadero (GEI), metano y óxido nitroso. Como un paso inicial hacia la obtención de información local, se midieron las emisiones de CH4 y N2O del suelo y de las plantas de arroz mediante la técnica de la cámara estática en experimentos en invernáculo y a campo en el este de Uruguay. En el experimento en invernáculo, se estudió el efecto del momento de inundación (21 y 45 días después de la emergencia) y de la fertilización nitrogenada (0 y 50 kg N ha-1) sobre las emisiones. La inundación temprana y la fertilización nitrogenada tendieron a aumentar las emisiones de N2O. En el experimento a campo, se estudió el efecto de la cobertura invernal y de la fertilización nitrogenada (0 y 82 kg N ha-1). Se detectaron mayores flujos de CH4 durante la etapa reproductiva de la planta en el tratamiento fertilizado con cobertura invernal previa de raigrás. El flujo de N2O fue máximo después de los baños. Los resultados indican que el uso del cultivo de cobertura podría incrementar las emisiones de GEI durante el ciclo del arroz. A pesar de las distintas prácticas de manejo del cultivo empleadas en Uruguay, los flujos de CH4 y N2O se encuentran dentro de los valores informados previamente para arrozales de otras partes del mundo.
