“…Similarly, Gentry et al (1992) observed increased gains from birth to 30 days of age in Suffolk lambs injected with 900 IU DL-α-tocopheryl acetate. Our results are also in accordance with other studies conducted in different breeds, with vitamin E supplemented in the concentrate (Álvarez et al, 2008;Ripoll et al, 2013) or in grass silage-based feed (Kasapidou et al, 2012). However, several other studies have demonstrated a beneficial effect of vitamin E treatment on growth traits in lambs (Macit et al, 2003a).…”

The effect of intramuscular injections of vitamin E on growth, carcass traits, intramuscular collagen (IMC) characteristics and decorin of growing lambs was studied. A total of 24 15-day-old Ile de France suckling male lambs were divided into two groups and weekly intramuscular injections of DL-α-tocopheryl acetate (control group, 0 IU; Vitamin E treatment, 150 IU) were given until the lambs were 64 days old. Lambs were individually weighted at 15, 29, 43, 57 days of age and at slaughter (71 days old). Dry matter intake and average daily weight gain were recorded. Hot and cold carcass weights were recorded and dressing percentages were calculated after dressing and chilling (2°C to 4°C for 24 h). Carcass shrink losses were calculated as well. Longissimus muscle (LM) pH and area were measured. The pelvic limb was removed and its percentage was calculated based on cold carcass weight. IMC and decorin analyses were assessed on LM and semimembranosus muscle (SM). DL-α-tocopheryl acetate treatment reduced ( P < 0.05) collagen maturity and increased ( P < 0.05) decorin in both LM and SM muscles of growing lambs, while it did not affect IMC content. In addition, vitamin E did not influence growth, carcass weight, dressing percentage, carcass shrink losses and area of LM but decreased ( P < 0.05) the pelvic limb percentage. The LM pH values were higher ( P < 0.05) in vitamin group than in control group. Furthermore, different IMC characteristics between the muscles ( P < 0.01) were apparent. Multiple intramuscular injections of DL-α-tocopheryl acetate influence extracellular matrix in lambs, which could affect meat tenderness.

“…However, it has been reported that there is a higher α-tocopherol accumulation in skeletal muscle of lambs intramuscular injected (Salvatori et al, 2004) or supplemented (Ripoll et al, 2013) with vitamin E when compared with control lambs. Lamb growth performance are presented in Table 2.…”

“…The percentage of polyunsaturated (PUFA), monounsaturated (MUFA) and saturated (SFA) fatty acids were calculated. Intramuscular lipid oxidation was determined according to the method of Ripoll et al (2013b) at 7 d of air exposure. The thiobarbituric reactive substances (TBARS) are expressed as milligrams of malondialdehyde (MDA) per kilogram of muscle.…”

The aim of this study was to analyse three commercial beef categories of the ‘Serrana de Teruel breed’ to define the appropriate commercial option. Twenty ‘Serrana de Teruel’ male calves at 9 months were assigned to the commercial beef categories (young bulls, bulls and steers), slaughtered at 12, 22 and 22 months of age, respectively. The in vivo ultrasound backfat thickness was greater than the dorsal fat thickness, and the young bulls and steers had a similar fat thickness, that was greater than the bulls in both areas. The slaughter weight and cold carcass weight were significantly different between the commercial categories. However, the differences were not sufficient to modify the dressing percentage, carcass conformation and fatness degree between the young bulls and bulls. The maximum stress of the muscle at 7 d of ageing was lower in the steers than in the young bulls and bulls. In general, the lightness of the meat in the bulls was lower than that in the young bulls and steers. The subcutaneous fat of the bull carcasses had a vivid colour and stored more carotenoids than that of the young bulls and steers. Hence, bulls produced heavier and better conformed carcasses with more edible meat and less fat than the other categories. However, steers are recommended to produce large carcasses with more trim and cover fat than the other categories. Finally, it seems that bulls are the most suitable commercial category to ‘Serrana de Teruel’ breed.

“…The difference in results may have been due to sheep weights at slaughter: in our experiment slaughter weights were around 33kg, while Poornahavandi and Zamiri (2008) slaughtered animals weighing more than 53kg. It has been reported that fattening to increase slaughter weight also increases fat deposition (Safdarian et al, 2008).…”

The purpose of this study was to determine how feeding sheep coffee pulp affects carcass characteristics and what changes occur in physicochemical, antioxidant capacity and oxidation of the meat during refrigerated storage. The experiment was carried out in 15 Blackbelly lambs weighing an average 22.86±0.76kg. The animals were assigned to three treatments: T0=control diet, T1=diet with 8% coffee pulp, and T2=diet with 16% coffee pulp. After fattening for 56 days, the sheep were slaughtered and the carcasses assessed. The inclusion of 16% coffee pulp in the diet increased carcass dressing from 48.19 to 50.83% and decreased the amount of fat in rumen and intestines from 3.43 to 2.53% (P<0.05). The inclusion of coffee pulp in the diet did not alter the amount of crude protein or fat in meat or its oxidation and antioxidant capacity during refrigerated storage. However, the inclusion of coffee pulp in the diet decreased fat in the rumen and intestines, and thus increased the amount of usable meat.
