High fiber diet reduces stereotypic behavior of gilts but does not affect offspring performance
2021, Applied Animal Behaviour ScienceCitation Excerpt :Much of the concern regarding these behaviors stems from the fact that they are indicators of poor welfare (Broom, 1983; Broom and Fraser, 2015; Brouns et al., 1994; D’Eath et al., 2018; Mason, 1991, Meunier-Salaün and Bolhuis, 2015; Tatemoto el al, 2019). Poor welfare can lead to changes in performance, immune function, and behavior (Barnett et al., 1983). Moreover, the sows’ diet during gestation can modulate the subsequent behavior and welfare of piglets (Bernardino et al., 2016).
Effects of physical enrichment items and social housing on calves’ growth, behaviour and response to novelty
2021, Applied Animal Behaviour ScienceCitation Excerpt :Oostindjer et al. (2010) also demonstrated that physical enrichment (straw, wood shavings, peat, and branches) positively affected the feed conversion efficiency for piglets. These results may be attributed to the reduced stress in physically enriched living environments (Barnett et al., 1983). In contrast to the effect of physical enrichment, social housing had no effect on calves’ daily concentrate intake, average daily gain and concentrate feeding efficiency in this study.
Associations between skin lesion counts, hair cortisol concentrations and reproductive performance in group housed sows
2021, Livestock ScienceCitation Excerpt :Indeed, chronic stress associated with rough handling and heat stress can increase plasma protein and glucose levels, and also alter sow energy metabolism and nutrient digestion (Barnett et al., 1983; He et al., 2019). This could consequently lead to lower amounts of nutrients to be available for allocation to foetal development (Barnett et al., 1983; He et al., 2019). It is therefore possible that chronic stress associated with sustained aggression could have a similar effect on sow energy metabolism, with potentially negative consequences for offspring development and incidence of IUGR.
Influence of stocking density on weight gain and behavior of feedlot lambs
2013, Small Ruminant ResearchCitation Excerpt :Social relationships are important to help the animals deal with its environment, as social partners influence individual reactions to external events (Veissier et al., 1998). However, when group size becomes too large, the competition, aggression and stress may lead to reduced growth and weight gain (Barnett et al., 1983; Tan et al., 1991; O’connell et al., 2004). It can also be found when the area is too large that animals need to increase energy expenditure required for the movement to access feeding and watering (Turner et al., 2000).
Finishing diet, temperament and lairage time effects on carcass and meat quality traits in steers
2010, Meat ScienceCitation Excerpt :Calmer animals had higher ADG within both breeds (p < 0.05) and these results are also consistent with Voisinet, Grandin, Tatum et al. (1997), who reported higher ADG in calmer Bos indicus cross and Bos taurus. A depression of growth is the consequence of a series of acute or chronic responses due to human presence (Barnett, Hemsworth, & Mand, 1983; Hemsworth, Price, & Borgwardt, 1996) being more relevant with temperamental animals. In spite of being more excitable, Braford steers had higher ADG than Hereford ones (0.73 ± 0.05 and 0.53 ± 0.05, respectively; p < 0.05).
