The aim of the study was to determine if cattle breeds differing in their carcass characteristics also differ in the profiles of their leptin and metabolic hormones. Three breeds, Belgian Blue (BB) (n=12), Limousin (L) (n=12) and Aberdeen Angus (AA) (n=12) with varying ability to deposit fat and protein were compared. Blood, muscle and subcutaneous (SC) adipose tissue were sampled. Animal performance, carcass and meat characteristics were determined as well as plasma leptin concentration, leptin gene expression in SC adipose tissue, leptin-receptor gene expression in SC adipose tissue and plasma concentration of insulin, tri-iodothyronin (T3), thyroxin (T4) and cortisol. The BB bulls showed the lowest values of leptin gene expression (P<0.05). Values of plasma leptin concentration and of leptin-receptor gene expression tended to be lower in BB than in the other breeds. For a similar amount of adipose tissue (after normalisation), BB bulls showed a higher ratio of plasma leptin (P<0.05), whereas normalised leptin gene and leptin-receptor gene expressions did not significantly differ between breeds. Belgian Blue bulls also differed in their metabolic hormone profile, tending to show lower values of insulin, T3 and T4 than the two other breeds. Cortisol levels were significantly lower (P<0.05) in BB than in L and AA animals. [less ▲]

Les publications traitant des effets métaboliques des aliments enrichis en matière grasse dans l’alimentation du cheval sont nombreuses. Cet article s’intéresse d’abord au contexte de leur utilisation et à leurs caractéristiques, avant d’envisager leurs effets sur l’appétence et la digestibilité de la ration. Bien que le vocable d’aliment enrichi en matière grasse recouvre des réalités bien différentes en termes de composition, l’examen de la littérature indique qu’ils présentent globalement une bonne appétence et que la digestibilité de la matière grasse est particulièrement élevée. Ils pourraient ainsi constituer une alternative de choix à l’utilisation de quantités importantes de céréales, dont les effets négatifs sont aujourd’hui bien documentés. [less ▲]

Thirty-six young fattening bulls from three breeds (Belgian Blue, Limousin and Aberdeen Angus) were fattened over 5 months with fattening diets based either on sugar-beet pulp or on cereals. Fattening performance as well as carcass and meat characteristics were measured. There were few relevant effects of the diets on the parameters. The breeds also showed similar fattening features. However, the BB had higher killing-out proportion and their carcasses presented better scores in terms of conformation and fattening. The meat quality of the breeds differed, especially in terms of luminosity, redness and cooking losses. There were also significant influences of breed on the chemical composition of meat; fat content was lowest in Belgian Blue and highest in Aberdeen Angus. Such specificities could help to allocate breeds in appropriate niches in Belgium. [less ▲]

Thirty-six young finishing bulls from three breeds (Belgian Blue, Limousin and Aberdeen Angus) were fattened over five months with finishing diets based either on sugar-beet pulp or on cereals. Nutritional quality traits of meat - fat content and fatty acid composition with emphasis on the n - 6 and n - 3 polyunsaturated fatty acids - along with some organoleptic quality traits were measured. The Belgian Blue bulls had the lowest intramuscular fat content associated with lower saturated and monounsaturated fatty acid contents. The polyunsaturated fatty acid content did not differ to a large extent between the breeds, the Aberdeen Angus bulls showing slightly higher values. Relative to energy intake, the overall contribution of meat to the n - 3 fatty acid recommended intake was small, whatever the breed. By contrast, the contribution of meat to daily fat intake was of greater importance, especially for the Aberdeen Angus bulls. The quality traits of meat varied also according to the breed: compared to the Aberdeen Angus, the Belgian Blue bull meat had the stablest colour, the highest drip and the lowest cooking losses. The meat of Limousin bulls had intermediate characteristics for all the parameters. (c) 2006 Elsevier Ltd. All rights reserved. [less ▲]

Blood transport and hepatic metabolism of fatty acids in ruminants present several particularities. The plasma profile is characterized by a very small proportion of triacylglycerols-rich lipoproteins— chylomicrons and very low density lipoproteins — and a very high proportion of high density lipoproteins, which can reach 80 % of the total lipoproteins. This distribution is concomitant with a low triacylglycerol and non esterified fatty acids plasma content, but with very high esterified cholesterol and phospholipid contents. Futhermore, the ruminant is characterized by the secretion of the majority of very low density lipoproteins at intestinal level and by a very low hepatic capacity to export triacylglycerols in these lipoproteins ; ruminant is therefore more sensible to steatosis. Moreover, the intrahepatic lipogenesis of ruminant is reduced, with as results a dependence on fatty acids blood import, the fatty acids being then directed to one of the two major pathways of intrahepatic metabolism, oxidation or esterification into triacylglycerols.

From a biochemical point of view, in ruminants, there are two major groups of fatty acids. They are firstly the volatile fatty acids from the rumen metabolism of dietary carbohydrates, and secondly the fatty acids from the rumen metabolism of lipids. This second group is made of the fatty acids synthesized by the microorganisms of the rumen and the fatty acids originating from the hydrolysis of dietary triacylglycerols, which are mostly hydrogenated by microorganisms in the rumen before intestinal absorption. In such conditions, the absorbed fatty acids are always more saturated than the ingested fatty acids. [less ▲]

Energy metabolism of skeletal muscles in cattle is characterized by several specificities, mostly related to particularities of the digestive physiology. Energy metabolism of muscles relies on preferential utilization of some nutrients, such as volatile fatty acids and ketone bodies on the one hand, and glucose on the other hand, the contribution of non-esterified long chain fatty acids being limited. As for other species, nutrients utilization is influenced by the nature of muscle fibers, leading to preferential metabolic pathways. Energy metabolism can be either more oxidative, oxido-glycolytic, or glycolytic. Close relationships are found between energy metabolism, chemical composition of muscle - more particularly its fat level - and organoleptic quality of meat. [less ▲]

Fatty acids are member of the lipid family. They are aliphatic monocarboxylic acids with or without double bond. They are classified according different nomenclatures : the international systematic name, the omega nomenclature and the trivial names. Fatty acids are major compounds of oils and fats. Among the saturated fatty acids, C12, C16 and C18 fatty acids are the most widely distributed, whereas in the unsaturated fatty acids group, C18 with 1, 2 or 3 double bonds are the most important within the vegetable and animal terrestrian products. Fatty acids with 4 or more than 4 double bonds and 20 to 24 atoms of carbon are largely represented in the marine products. [less ▲]

The aim of this study was (i) to evaluate the effect of ovariectomy on daily energy requirement in Beagle dogs, and (ii) to evaluate the effects of ad libitum feeding with a high energy diet on energy consumption, body weight gain and blood metabolites in these spayed dogs. Four young adult female Beagle dogs were used. Ovariectomy induced a significant decrease of daily energy requirement in dogs. Ad libitum feeding, initiated 6 months after spaying, induced a significant increase in consumption in spayed dogs. This overconsumption was greatest during the first month of ad libitum feeding but continued for the entire 4 months of this period. When fed ad libitum, dogs gained excess body weight without significant effect on plasma cholesterol, triglycerides, glucose and insulin, at short term. These data suggest that energy intake should be strictly controlled to avoid excess weight gain in spayed dogs. [less ▲]
