“…No difference in carcass weights was observed by Myers et al (1999) for young steers managed at pasture for 82 days after weaning or fed concentrate, nor by Berge et al (1991) for young bulls managed at pasture or fed grass or maize silage (ad lib or rationed). Furthermore, bulls fed a total mixed ration (TMRlucerne and maize) for 5 months, managed at pasture for 6 months, then slaughtered at similar weights generated similar carcass characteristics as bulls fed concentrate for 6 months (Blanco et al 2014). In this latter study, the rotation TMR/pasture/TMR over a period of 10 months generated carcasses with lower conformation scores and carcass yield and higher fat scores.…”

To improve their income, European cattle breeders have to produce cattle carcasses with the best score on the EUROP system. The objectives of this study were to identify the rearing practices applied on farms at each period of a heifer's life and to study the relationship between these practices and the carcass characteristics. Farm surveys (n ¼ 45) were performed to assess the rearing practices. A factorial analysis of mixed data followed by a hierarchical clustering on principal components was performed for each life period. The clusters resulting from these typologies were related to the carcass characteristics (weight, conformation and fat scores). For the suckling period, the cluster characterised by a calving season in autumn, a short pasture period and systematic supplies of stored grass and concentrate in stall gave heavy carcasses with the highest conformation scores. For the growth period, the best cluster for producing favourable carcass characteristics was characterised by the longest pasture period, feeding the most stored grass and feeding a regular concentrate supply throughout the year. For the fattening period, the cluster characterised by the oldest age at the beginning of the period and at slaughter, slaughter in winter and autumn, a long pasture period and regular concentrate supply gave the heaviest carcasses with the highest conformation scores. This study highlights several rearing practices that could be used as a means to influence the carcass characteristics, and also the life periods at which animals are sensitive to changes in management practices to improve weight and conformation scores. HIGHLIGHTSCarcass characteristics are related to rearing practices applied at each life period of heifers. Rearing practices can be used as a means to influence carcass characteristics.

“…The continuous provision of an unnaturally energy‐rich diet and reduced physical activity under zoo conditions can explain this difference (Hatt & Clauss, ). The positive correlation between diet and growth rate is well‐known in farm animals (Blanco et al, ; Borton et al, ; Pla, ), has been detected in reptiles (Ritz et al, ), as well as in several primate species (Leigh, ) and nutria (Głogowski et al, ) and might exist in further wildlife species. Moreover, dependence of height growth on caloric intake has been demonstrated in humans (Berkey, Gardner, Frazier, & Colditz, ; Fomon et al, ).…”

Weigh and see—Body mass recordings versus body condition scoring in European zoo elephants (Loxodonta africana and Elephas maximus)

Regular body mass (BM) monitoring plays a key role in preventative health care of zoo animals. In some species, including African (Loxodonta africana) and Asian elephants (Elephas maximus), the process of weighing can be challenging, and alternative methods such as visual body condition scoring (BCS) have been developed. We investigated the temporal development of both parameters regarding correlation patterns between them, and their suitability as monitoring measures in dependence of an elephant's life stage. While BM is more suitable in calves and juveniles under the age of 8 years, both BM and BCS are considered equally reliable in adult elephants. In elephants over the age of 40 years, BCS might be more suitable for assessing the physical status. Independent of species and sex, juvenile zoo elephants grow in BM nearly linearly with age, and reach a higher BM at an earlier age compared with conspecifics of free‐ranging and semi‐captive populations in the countries of origin. The BCS typically remains constant during this life stage, seemingly unaffected by growth. In adult animals, breeding females have a lower BM and BCS than nonbreeders, and BM and BCS typically indicate fluctuations in the same direction. In geriatric elephants (>40 years) a drop in BCS occurs commonly, while BM may even increase in this life stage. We recommend regular body mass recording in zoo elephants to enhance our knowledge of body mass development and allow the formulation of objective practical recommendations. BCS presents a valuable and simple tool for complementary monitoring of an elephant's condition, especially in adult and geriatric individuals.

“…36 A finishing period of 84 days for TMR beef increased ADG by 46.6% when compared with grazing steers, 16 whereas the finishing period (56 days) in the current experiment increased ADG by 31.4%. 9 It could be hypothesized that despite the compensatory growth in both studies, the shorter finishing period in the current experiment may have not allowed a reduction in the connective tissue's impact on toughness. 43 Beef tenderization in the current experiment was similar to that of concentrate-fed young bulls slaughtered at 550 kg LW, 44 estimated using the maximum load, which was approximately 13% in the first week and 16% in the second week.…”
