title: [Characterization of the nutritional status of wild boars in forest surroundings on the basis of mesenteric fat and blood parameters].
abstract: Blood samples as well as mesenteric fat for measurement of biochemical parameters were taken from 51 wild boars (36 males, 15 females) slaughtered over a period of one year. The relative weight of the mesenteric adipose tissue as well as its lipid content showed a maximum in the autumn and regularly decreased until the end of the next summer. The lipid content thus ranged from 39 to less than 10% at the end of the summer. Variations in the blood levels of some metabolites measured in the plasma were compared with the nutritional status of the animals. The values showed a high glycaemia (158 mg/dl) that varied little with the season. In contrast, the cholesterol level decreased from the autumn till late winter with a minimum value in March (89 to 50 mg/dl). The level of total proteins, which was low from February to September, increased during the autumn-winter period, independently of the albumin content which seemed to be constant. The urea content was highly variable thus masking possible seasonal variations. The creatinine level showed a minimum in the autumn (2.0 mg/dl) and a maximum in the summer (2.9 mg/dl), a period with little abundant food supplies. Thus, the wild boar exhibits large seasonal variations of its metabolism and constitutes body reserves which are mobilised during periods of reduced food availability. The mesenteric fat weight as well as the blood levels of cholesterol and creatinine seem to characterize rather well the nutritional status of this animal.
