Dorper and Merino lamb carcasses of the A age group with a fat code 2 (±7% SCF) from three main production areas in South Africa were used for this study. The right sides of the carcasses were used to determine the raw nutrient and physical (carcass) composition of each cut as well as for the whole carcass by calculation. Three cuts (shoulder, loin and leg) from the left side were cooked in order to determine the nutrient composition thereof. Nutrients showing the greatest differences between raw and cooked treatments, were protein, total fat, C16:0 saturated fatty acid (SFA) and C18:1n9c monounsaturated fatty acid (MUFA). Moisture losses due to cooking resulted in an increase in the protein and cholesterol concentrations of the cooked cuts. Iron content was lower in the cooked loin cut but increased in the cooked leg cut when compared to the corresponding raw cuts. The vitamin B content of all three cooked lamb cuts was lower, although not significantly so, than that of the corresponding raw cuts. Lamb is a good source of protein, iron and the B vitamins, especially vitamin B 12 when cooked.

“…Esta enzima catalisa a fosforilação da adenosina difosfato (ADP) do fosfato de creatina, tornando a ATP disponível para a contração muscular (Purchas et al, 2004). Thomassian et al (2007) relataram que o pico de CK ocorre 6 horas após o exercício, e que após esse período os valores são semelhantes ao de repouso.…”

RESUMO.O presente estudo objetivou avaliar o comportamento das enzimas creatina quinase (CK) e aspartato amino transferase (AST) antes e imediatamente após o desafio das provas atléticas de apartação e três tambores e a influência do sexo. Foram utilizados 41 equinos da raça Quarto de Milha, sendo 20 animais destinados à prova de apartação e 21 animais para a prova de três tambores. Amostras de sangue foram obtidas dos animais duas horas antes das provas e no máximo cinco minutos após para determinação das enzimas. Os resultados permitiram concluir que a atividade sérica das enzimas CK e AST foi significativamente mais elevada após as provas de apartação e três tambores e que os valores de AST foram mais elevados nas fêmeas e os valores séricos de CK foram menores nos machos não castrados em relação aos machos e às fêmeas.Palavras chave: bioquímica sérica, cavalos, enzimas musculares, exercício.Serum activities of aspartate amino transferase, creatine kinase in equine subjected two competitions ABSTRACT. The present study aimed to evaluate the behavior of the enzymes creatine kinase (CK) and aspartate amino transferase (AST) before and immediately after Team Penning and Barrel race competitions and the influence of sex. Were used 41 Quarter Horses, with 20 animals for Team Penning competition and 21 for Barrel race. Blood samples were obtained from animals two hours before and five minutes after the race for enzymes determination. The results showed that the serum CK and AST activity were significantly higher after the exercises. The serum AST activity was higher in female and the serum activity was lower in castrated males compared to non-castrated males and females.Keywords: serum biochemistry, muscular enzyme, exercise, equine. IntroduçãoA avaliação do desempenho dos cavalos atletas é fundamental para o reconhecimento de suas habilidades e a intensidade de exercício mais adequada em diferentes fases de treinamento. O exercício causa alterações reversíveis na ultraestrutura do músculo esquelético equino, como elevações na permeabilidade do sarcolema e das proteínas musculares, como creatina quinase (CK), aspartato amino transferase (AST) e mioglobina que são liberadas na circulação (Mc Cutcheon et al., 1992).

“…The coenzyme is naturally present in most foods but in different amounts. As for muscle tissue, its concentration depends on a slaughter animal species (6,10), primal cut (6), gender (17), muscle kind (14,16,18), and oscillates from 13.8 up to 45 µg/g in fish, 0.10-130 µg/g in shellfish/molluscs, 0.08 -7.47 µg/g in vegetables, and finally, 0.51-9.48 µg/g in fruits (6,9).…”

The research material included 96 slaughter rabbit carcasses. Half of them came from the animals managed in small-scale backyard farming units where animals were fed a natural ingredient diet, while the other half was from rabbits kept under commercial production conditions and fed commercial rabbit pellets. The thigh and saddle muscle samples were collected from each carcass to establish a content of ubiquinone (CoQ10) and crude protein along with its collagen level. Determination of tissue coenzyme Q10 (UQ10) was carried out by high-performance liquid chromatography with some modification. Crude protein concentration was estimated using Kjeldahl procedure, while total collagen content by the method of Stegemann modified by Hurych-Chvapil, using hydrolysis according to Möhler and Volley. Ubiquinone level in slaughter rabbit tissue ranged between 76 and 127 μg/g tissue. The studies indicated that rabbit rearing system and muscle type are determinants of CoQ10 content. Meat of rabbits managed under the traditional backyard farming system exhibited higher CoQ10 concentration as compared to that determined in rabbits from the commercial rabbitry. Additionally, the CoQ10 level in the saddle was significantly higher than that in the thigh muscles, and the relationships was noted in both types of rabbit production systems. When the CoQ10 content was expressed per gram of fibrillar protein, there were not significant differences between saddle and thigh muscles. The correlation coefficient between ubiquinone and fibrillar protein averaged to 0.94. The studies also demonstrated a higher protein level in the saddle than in thigh muscles. However, no differences in protein concentration were reported in respect to the rabbit farming system. The protein composition in the saddle muscles, irrespective of a rabbit production system, revealed significantly lower collagen content compared to the proteins in thigh muscles. The obtained results and data from literature provide evidence that rabbit meat, especially from the traditional (organic) management system, is one of the best sources of animal protein and ubiquinone Q10.
