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:
Potential consequences of climate change on crop production can be studied using mechanistic crop simulation models. While a broad variety of maize simulation models exist, it is not known whether different models diverge on grain yield responses to changes in climatic factors, or whether they agree in their general trends related to phenology, growth, and yield. With the goal of analyzing the sensitivity of simulated yields to changes in temperature and atmospheric carbon dioxide concentrations [CO2], we present the largest maize crop model intercomparison to date, including 23 different models. These models were evaluated for four locations representing a wide range of maize production conditions in the world: Lusignan (France), Ames (USA), Rio Verde (Brazil) and Morogoro (Tanzania).
While individual models differed considerably in absolute yield simulation at the four sites, an ensemble of a minimum number of models was able to simulate absolute yields accurately at the four sites even with low data forcalibration, thus suggesting that using an ensemble of models has merit. Temperature increase had strong negative influence on modeled yield response of roughly 0.5 Mg ha1 per °C. Doubling [CO2] from 360 to 720 lmol mol1 increased grain yield by 7.5% on average across models and the sites. That would therefore make temperature the main factor altering maize yields at the end of this century. Furthermore, there was a large uncertainty in the yield response to [CO2] among models. Model responses to temperature and [CO2] did not differ whether models were simulated with low calibration information or, simulated with high level of calibration information. MenosAbstract:
