“…Regarding reactivity towards humans, our estimate (h 2 = 0.23) was in agreement with those found previously in dairy cattle [13,40,46], and beef cattle [27,31]. The heritability estimates found in the present study thus provide evidence in support of the possibility of selecting for emotional traits in sheep.…”

-A total of 1347 weaned lambs from eight genotypes were tested over five consecutive years: Romanov (ROM) and Lacaune (LAC) pure breeds, the two F1 crossbreeds (RL and LR) and the offspring of ewes from these four genotypes sired with Berrichon-du-Cher rams (BCF). The lambs were individually exposed to three challenging tests involving novelty, human contact and social isolation. Ten synthetic variables were used to express social reactivity (i.e., active vs. passive strategy), exploratory activity and reactivity to humans. BCF crossbreds were more active (i.e., high bleats, locomotion and attempts to escape) than purebreds and F1. In contrast, ROM expressed more passive responses (i.e., low bleats and vigilance postures) than LAC and BCF crossbreds. In addition, ROM approached a motionless human less and had longer flight distances to an approaching human than did LAC and BCF crossbreds. When restrained, ROM, and to a lesser extent B×ROM and B×LR, avoided human contact more than did LAC, RL and B×LAC. Most of these differences were explained by direct additive genetic effects while maternal influences or heterosis effects were rarely significant. The highest heritability was for high bleats (h 2 = 0.48). Females were more active and avoided human contact more than did males.genetics / emotional reactivity / human contact / social isolation / sheep

“…Finally, the posterior mean estimate of the heritability of DOC was 0.19, confirming the evidence of additive genetic variance for this trait, as suggested by the studies of Le Neindre et al (1995) and Phocas et al (2006) in Limousin cattle.…”

Survival or longevity is an economically relevant trait in cattle. However, it is not currently included in cattle selection criteria because of the delayed recording of phenotypic data and the high computational demand of survival techniques under proportional hazard models. The identification of longevity-correlated traits that can be early registered in lifetime would therefore be very useful for beef cattle selection processes. The aim of this study was to estimate the genetic correlation of survival (SURV) with: growth -birth weight (BW), weight at 120 days (W120), weight at 210 days (W210); carcass -cold carcass weight (CCW), conformation (CON), fatness (FAT) and meat colour (COL); teat morphology -teat thickness (TT), teat length (TL) and udder depth (UD); leg morphology -forward (FL) and backward legs (BL); milk production (MILK) and docility (DOC). In the statistical analysis, SURV was measured in discrete-time intervals and modelled via a sequential threshold model. A series of independent bivariate Bayesian analyses between cow survival and each recorded trait were carried out. The posterior mean estimates (and posterior standard deviation) for the heritability of SURV was 0.05 (0.01); and for the relevant genetic correlations with SURV were 0.07 (0.04), 0.12 (0.05), 0.10 (0.05), 0.15 (0.05), 20.18 (0.06), 0.33 (0.06) and 0.27 (0.15) for BW, W120, W210, CCW, CON, FAT and COL, respectively.

“…The scale of the handling score ranged from 0 to 4 and the release score ranged from 0 to 2 (Table 1). The use of a subjective measure of calmness or stress is a commonly used method for describing behaviour (Benhajali et al 2010;Le Neindre et al 1995;Réale et al 2000). During all captures, animals were handled by the same handling team lead by L.J.…”

The use of box-traps for wild roe deer: behaviour, injuries and recaptures

2017

Tracking devices are commonly used to locate and monitor wild animals for studying spatial ecology and survival rates. There is growing interest in capture effects, partially to minimize the impact on the study species, but also for animal welfare reasons. This study aims to examine roe deer behaviour in box-traps, when restrained, when released and during recaptures to quantify injuries and deaths over a period of 41 years. We use data from 2911 captures from 926 individuals between 1973 and 2014. We recorded behaviour inside the box-traps over two seasons. We also recorded behavioural data from 671 catches of 346 individuals during six seasons to study habituation. Additionally, we discuss boxtraps in relation to ethological theory and animal welfare. Over a 41-year period, one roe deer suffering from starvation was found dead in a trap (0.035%), which cannot be solely related to capture (N = 926). About 58% of all roe deer were recaptured at least once during their life time. There was a low prevalence of injuries (0.5% of the captures, N = 2911), and they occurred predominately to the nose or antlers in velvet (in males). During the first hour after capture, animals typically stand very tense between eating bouts. Thereafter, the deer tended to move more softly and exhibited resting behaviours (e.g. lying down). Overall, we conclude that this method of capture and handling had very low impact on the welfare or survival of roe deer, which also habituated to recapture over successive events. • We recorded recaptures, injuries and behaviour during restraint in boxtraps.• About 58% of roe deer were recaptured during their life time.• The estimated direct mortality and wounds was 0.035 and 0.5% respectively.• Roe deer habituate to the capture and become calmer at consecutive captures.Electronic supplementary material The online version of this article
