When compared to animals of the dual purpose type in the same breed, Belgian Blue double muscled bulls exhibit, at least, similar average daily gain with lower feed intake. The higher feed efficiency in the double muscled type is mainly explained by the composition of the weight gains, the muscle content is minimum 60 kg higher and the fat content 30 kg lower than in the dual purpose type when slaughtered at a similar liveweight. In both types, the dressing percentage and the lean meat proportion in the carcass increase with final liveweight.The chemical composition and the sensory characteristics of meat are also influenced by double muscling. The fat content is reduced and the polyunsaturated fatty acids proportion is increased in the double muscled type, resulting in a nutritional advantage. The difference in sensory characteristics could be, only partially, explained by the faster post mortem pH drop. The paler meat is mainly related to the myoglobin content. The advantage of the double muscled type in terms of tenderness, due to a low collagen content, is not exhibited in a "choice" cut of the carcass with a low level of collagen. Finally, according to most of the available data, the water holding capacity of meat of double muscled animals seems not very different.The concentrations of several blood metabolites indicate a partition of the absorbed nutrients propitious to protein deposition and unpropitious to fat deposition in double muscled animals. During the fattening period, this specific partition can be related to endocrine characteristics, mainly growth hormone and insulin. [less ▲]

An experiment was conducted to study effects of dietary vitamin E supplementation on animal performance, slaughter characteristics and meat quality traits in Belgian Blue double-muscled bulls. Two groups of six bulls each (404 kg) were offered (close to ad libitum) a fattening diet based on sugar beet pulp for 154 days, at which time they were slaughtered. The diet given to the control group (CG) contained 12.5 mg vitamin E/kg concentrate. The vitamin E-treated group (VG) received the same concentrate plus a supplement of 1000 mg vitamin E per bull daily. Steaks from m. longissimus thoracis were used to determine meat quality characteristics, α tocopherol concentration and thiobarbituric acid reactive substances content (TBARS), an indicator of oxidation rancidity. Supplementation had no influence on performance or carcass characteristics. The main findings were that vitamin E doubled the muscle alpha tocopherol level (1.9 vs. 0.9 mg/kg; P<0.001), lipid oxidation was suppressed as indicated by TBARS values (P<0.01 at days 7, 9, 11 and 14 after slaughter), but muscle colour was not significantly affected although a* (redness) tended to be higher for VG.

The aim of the present study was to evaluate the effects of three fibres (sugar-beet fibre, guar gum and inulin) incorporated in the basal diet of healthy dogs at 7 per cent of dry matter (DM). Parameters examined included stool output, water consumption, nutrient digestibility and fasting and postprandial plasma metabolites. All fibres increased wet faecal output; an increase in faecal DM output being observed with sugar-beet fibre only. Sugar-beet fibre and inulin increased daily water consumption. Sugar-beet fibre and guar gum decreased DM digestibility. The three fibres diminished organic matter and crude protein digestibility while ether extract digestibility was decreased by guar gum and inulin. Guar gum induced lower postprandial insulin, alpha-amino-nitrogen and urea plasma concentrations. Guar gum also lowered fasting cholesterolaemia. Sugar-beet fibre and inulin showed no metabolic effects. These physiological properties suggest that guar gum would be a suitable ingredient for dietary therapy of chronic diseases such as diabetes mellitus or hyperlipidaemia in the dog. [less ▲]

Un maïs plante entière a été ensilé à trois stades de maturité différents (S1, S2, S3) correspondant à des teneurs respectives en matière sèche de 25,1 (S1), 29,8 (S2) et 32,3 % (S3). La production de matière sèche s'élevait à 10,7 ; 11,1 et 11,7 tonnes par hectare. Chacun de ces ensilages, distribué à des taureaux à l'engraissement, a été supplémenté par des pulpes séchées, du tourteau de soja, des sels minéraux et des vitamines. Le stade de maturité n'a pas affecté les teneurs en cendres, cendres insolubles, extrait éthéré ou protéines ; cependant une réduction significative de la teneur en fibre ADF a été enregistrée avec S3. La digestibilité de la matière sèche et de la matière organique de la ration mesurée in vivo sur des taureaux en cages à bilan ainsi que celle du maïs ensilage n'ont pas été non plus influencées par le stade de maturité. En revanche, la digestibilité de la fibre ADF a été significativement plus faible pour S3 par rapport à S1 et S2 (62,1 vs 67,2 ou 65,6 %, p < 0,05 pour la ration; 54,1 vs 63,3 ou 60,7 %, p < 0,001 pour le maïs). Quant aux potentialités du rumen à dégrader les aliments, il est à noter que la dégradabilité totale par la méthode in sacco des différents composants testés a été supérieure dans le rumen des animaux qui recevaient le maïs à teneur en matière sèche élevée. Il n'y a pas eu d'effets significatifs du stade de maturité sur les performances animales durant un essai de 5,5 mois dans le cas d'une alimentation ad libitum. A partir de l'indice de consommation, du gain total de poids vif et de la production de matière sèche par hectare, il était possible d'estimer que 13,8, 14,2 et 15,7 taurillons pouvaient être engraissés respectivement à partir des ensilages de maïs S1, S2 et S3 produits par ha.

Cette étude relate les effets de la distribution de deux rations enrichies en pulpes de betterave ou de chicorée (7 p.100 ADF dans la matière sèche) en comparaison à une ration témoin sur les paramètres fécaux, la digestibilité des principaux nutriments et plusieurs paramètres biochimiques (glucose, insuline, azote alpha-aminé, urée, cholestérol et triglycérides) mesurés à jeun ou pendant six heures après le repas chez huit chiens adultes en bonne santé. Les régimes enrichis en pulpes ont entraîné une augmentation significative de l'excrétion fécale totale, de l'excrétion de MS dans les matières fécales, une diminution de la teneur en MS des fèces ainsi qu'une diminution des coefficients de digestibilité des principaux nutriments. Le régime contenant la pulpe de betterave a entraîné une diminution de la glycémie à jeun, de l'insulinémie et des concentrations en triglycérides postprandiales, des concentrations en urée et en cholestérol mesurées avant et après le repas. Le régime contenant la pulpe de chicorée a provoqué une diminution de l'insulinémie postprandiale, des concentrations en urée et en cholestérol à jeun et après le repas. Ces deux types de pulpes, semblables par leur composition, induisent les mêmes types d'effets sur les paramètres fécaux et la digestibilité des nutriments, mais les effets systémiques sont plus importants lors de la distribution de pulpes de betterave.

Metabolism of muscle growth in the hindquarter was investigated by the arterio-venous difference (AVD) technique in Belgian Blue double-muscled type bulls at maintenance or at fattening. The bulls were fitted with an aortic ultrasonic blood flow probe and with catheters in the aorta and vena cava. They were offered a diet allowing for maintenance (MP) during a period of 15 d, at the end of which measurements were made over 3 d. Bulls were then given a fattening diet (FP) and the measurements were repeated. Arterial blood flow was approximately 1 L/min greater when the bulls were standing than when lying. Blood flow was 2 L/min higher during FP than during MP. The AVD and uptake of glucose were maximal at 1400 and 1600. Uptake of alpha-amino nitrogen decreased immediately after a meal. The increase in glucose from MP to FP fitted very well with the calculated energy needs for muscle growth. The AVD and uptake of alpha-amino nitrogen, total amino acids, and total nonessential amino acids were negative during MP and positive and significantly higher during FP. There was also a significant increase in AVD and uptake of essential and branched-chain amino acids when the bulls were changed from MP to FP. When changing from maintenance to fattening, the incremental glucose and amino acid hindquarter uptake provided energy and supply for muscle protein accretion, respectively. The level of alanine transamination was also sharply reduced. [less ▲]
