“…The pH 10 differed significantly among breeds (P < 0.001). The animal temperament and the management prior to slaughter are known to affect stress and energy reserves in the meat that will affect ultimate pH (Miranda-de la Lama et al, 2013). Differences in genetic susceptibility to stress among breeds are well known (Miranda-de la Lama et al, 2013).…”

“…The animal temperament and the management prior to slaughter are known to affect stress and energy reserves in the meat that will affect ultimate pH (Miranda-de la Lama et al, 2013). Differences in genetic susceptibility to stress among breeds are well known (Miranda-de la Lama et al, 2013). In particular, animals with muscular hypertrophy having a more excitable temperament and are more prone to stress than non-hypertrophic animals (Oliv an et al, 2004).…”

Summary The objective of this study was to determine the variation of the colour of longissimus thoracis muscle within and among fifteen European cattle breeds reared under comparable management conditions. A total of 436 unrelated purebred young bulls from fifteen European breeds (Aberdeen Angus, Highland, Jersey, South Devon, Danish Red, Holstein, Simmental, Asturiana de las Montañas (also known as Casina), Asturiana de los Valles, Avileña‐Negra Ibérica, Pirenaica, Marchigiana, Piemontese, Charolais and Limousin) were reared in five experimental research centres in the United Kingdom, Denmark, Spain, Italy and France. The pH of M. longissimus thoracis was measured at 24 h and after 10 days of ageing and colour at 48 h and 10 days. Two generalised linear models, Pearson correlations and a hierarchical cluster analyses were carried out. Lean meat colour differed significantly between breeds, and these fifteen European breeds could be grouped according to four classes of commercial interest: ‘very bright and pale‐red’, ‘bright and pale’, ‘red’ and ‘dark and dull red’. These groups were partially related to body size and carcass traits, fatness and muscle development and structure, and were controlled by differences in gene expression within each breed.

“…In addition, the number of animals in the group may affect the social behaviour of young cattle (Estevez et al, 2007). Although several investigations have evaluated the influence of social hierarchy (Miranda-de la Lama et al, 2013) and group size (Abdelfattah et al, 2013) on cattle growth and welfare, no studies have examined the effect of group size on behavioural and immune responses of young male buffaloes. Therefore, this study was designed in two experiments concerning fattening male buffaloes.…”

The effects of different dietary levels of maize silage (10% v. 36% DM) and group size (7 v. 14 animals) were assessed on growth performance and in vivo digestibility of 28 male fattening buffaloes. In addition, the effects of diet on meat quality and group size on behaviour and immune response were separately evaluated. Animals were weighed and assigned to three groups. The high silage -low size group (HL) was fed a total mixed ration (TMR) containing 36% DM of maize silage and consisted of seven animals (age 12.7 ± 2.6 months; BW 382.2 ± 67.7 kg at the start of the study). The low silage -low size group (LL) was fed a TMR containing 10% DM of maize silage and consisted of seven animals (age 13.0 ± 2.7 months; BW 389.4 ± 72.3 kg). The high silage -high size group (HH) was fed the 36% maize silage DM diet and consisted of 14 animals (age 13.9 ± 3.25 months; BW 416.5 ± 73.9 kg). Total space allowance (3.2 indoor + 3.2 outdoor m 2 /animal) was kept constant in the three groups, as well as the ratio of animals to drinkers (seven animals per water bowl) and the manger space (70 cm per animal). Growth performance, carcass characteristics and digestibility were influenced neither by dietary treatment nor by group size, even if the group fed 36% maize silage diet showed a higher fibre digestibility. No effect of diet was found on meat quality. Group size did not affect the behavioural activities with the exception of drinking (1.04 ± 0.35% v. 2.60 ± 0.35%; P < 0.01 for groups HL and HH, respectively) and vigilance (2.58 ± 0.46% v. 1.20 ± 0.46%; P < 0.05 for groups HL and HH, respectively). Immune responses were not affected by group size.

“…In confinement system, food can be a limiting resource when it is provided in a restricted way or when the available space in the feeder is not sufficient for all animals to feed simultaneously (Estevez et al, 2007). The effects of space restriction in feeders have been approached in broiler chickens and laying hens (Estevez et al, 1997;Hughes et al, 1997), dairy and beef cattle (Olofsson, 1999;Miranda-De La Lama et al, 2013), goats (Jorgensen et al, 2007;Van et al, 2007), and sheep (Henderson, 1985;Boe et al, 2006;Boe and Andersen, 2010). These surveys have reported changes in group behavior, increase in aggressive incidents, and reduction in feed intake and weight gain when evaluating animals with reduced feeding spaces.…”

Available space in feeders for housed sheep: social behavior and performance

This study was designed to assess the effects of feeding space availability on social behavior and performance of housed crossbreed sheep through the use of three different types of feeders. Thirty-six crossbreed ewes (Santa Inês × Dorper; 2-3 years old) with initial body weight of 34.99±4.28 kg were randomly assigned to a 3 × 3 (feeder type × available space at the feeder) factorial arrangement among nine pens. Pens had one of three feeder types (concrete bunk, plastic, or wood barrel) and one of three amounts of available space in the feeder (0.33, 0.25, or 0.20 m animal −1 ). Total dry matter intake/pen, dry matter intake per animal, total weight gain/pen, daily weight gain/animal, and food waste were evaluated. Percentage of time spent at feeding and frequency of aggressive behaviors/12 h were recorded. We observed a higher total daily weight gain in ewes with a feeding space of 0.33 and 0.25 m animal −1 . The wastes were essentially insignificant for wood feeders in all feeding space treatments. The average number of aggressive behaviors was lower (P< 0.05) for animals kept in pens with feeding space of 0.33 m animal −1 than for those maintained in pens with feeding space of 0.20 and 0.25 m animal −1 . Ewes with feeding space of 0.33 m animal −1 fed simultaneously 54% of the time, while among pens with feeding spaces of 0.25 or 0.20 m animal −1 , this period was reduced to 41 and 30%, respectively. An available feeding space of 0.33 m animal −1 is recommended for adult housed ewes, once it favors simultaneous access, lower competitive interactions at the feeder, and less variation in terms of individual weight gain among ewes.
