Two groups of 12 Belgian Blue double-muscled cull females were used successively in a 2-year repeated experiment and divided into three groups according to age, allowing four animals per group each year. The aim of the trial was to relate, during the finishing period, the metabolic and endocrine parameters with age. Females were fattened with a diet based on maize silage and were blood sampled on several occasions. The average daily gain (ADG) decreased with the age of the cows. Plasma glucose and triglycerides decreased also with age while the youngest females showed lower concentrations of urea than those older. The composition of plasma non-esterified fatty acids also differed considerably between groups. The hormones that best related with ADG were IGF-1 and insulin. Plasma concentrations of thyroid hormones were lower in the oldest animals. No difference between groups was found for GH. Heifers presented lower concentrations of GH and IGF-1 than those reported elsewhere in fattening bulls of the same breed. It may be concluded that in Belgian Blue double-muscled females, glucose, IGF-1 and insulin are good indicators of the growth potential. Young adult cows presented intermediate characteristics of metabolic and endocrine status that were close either to younger or to older cows. [less ▲]

A 4-year experiment has been conducted on finishing Belgian Blue cull cows of double-muscled type in order to study the effects of diets containing adequate levels of metabolizable protein, but either normal (NENP), low (LENP) or medium (MENP) levels of metabolizable energy, on animal performance, carcass and meat characteristics, and plasma metabolites and hormones. The LENP diet was offered during the whole (LENP group) or second half of the finishing (NENP-LENP groups), and the MENP diet during the whole finishing (MENP group). The degree of fatness required for the slaughter of animals from NENP groups was close to 4.5 (scale from 0 (very lean) to 5 (very fat)). In each underfed group, the slaughter of the animals was synchronized to that of NENP cows, by degressive degree of fatness. The same duration of finishing was thus obtained for all groups. The experimental feeding strategies reduced the amounts of fat deposited in the carcass and the meat while muscle deposition was remarkably preserved. The proportions of saturated and monounsaturated fatty acids in intramuscular fat were also decreased while their proportions increased in plasma free fatty acids. Plasma insulin levels were also reduced and those of IGF-1 were, surprisingly, maintained. The low energy diet promoted thus the settlement of a discrete lipolytic state while high levels of IGF-1 preserved muscle deposition. This feeding strategy should be evaluated in other breeds of cattle. [less ▲]

In order to measure Animal performance and, carcass and meat characteristics of Belgian Blue double-muscled culled females, a fattening trial was carried out on a total of 78 animals. Fifteen females were slaughtered at the beginning of the trial and 63 were fattened on a maize silage based diet. The initial average live weight was 571.2kg. The total fattening gain was 91.1 kg for a period of 91.4 days. At slaughter, the warm carcass weight was 405.9kg and the killing-out proportion 63.3%. The carcasses were characterised by a high proportion of muscles (67.6%) and rather low proportions of adipose tissue (18.2%) and bones (14.2%). The muscle and adipose tissue accretions were 36.0 and 28.2 kg. Meat was lean as indicated by high protein content (88.5%) and low fat content (6.6%) in dry matter. A high proportion of polyunsaturated fatty acids was also found (6.8 mol %). [less ▲]

The effects of different sequences of food restriction and fattening have been studied on plasma metabolites and hormones in double-muscled Belgian Blue bulls. Twenty animals were divided into five groups. The first group (control, CG) was given, ad libitum, a fattening diet based on sugar-beet pulp. In G2 and G3, fattening was interrupted after 103 and 187 days, respectively, by a period of food restriction lasting about 2 months during which the animals received a maintenance ration. They were finished with the same diet as CG. The last two groups, G4 and G5, received a limited amount of the restriction diet to support 0.5 and 0 kg gain per day, respectively, for 4 months, before being fattened as CG. Plasma glucose, alpha-amino nitrogen, non-esterified fatty acids, urea, creatinine, thyroxine (T4), 3, 3', 5'-tri-iodothyroxine (T3), and insulin-like growth factor-1 (IGF-1) were measured in blood samples taken every 2 weeks. Plasma GH and insulin profiles were measured in serial blood samples obtained at three different times during growth. Animals that showed compensatory growth had lower plasma urea, associated with high levels of T3, T4 and IGF-1. Animals from G2 and G3 failed to show compensatory growth. In Belgian Blue bulls, compensatory growth is markedly affected when food restriction is severe or fattening interrupted. [less ▲]
