Body fat composition of the mink (Mustela vison), polecat (Mustela putorius), and the raccoon dog (Nyctereutes procyonoides) was studied. The animals were fed a wet diet, supplemented with 5 % lard (LA) or fish oil (FO) for 5-6 months. At pelting, five animals per dietary group were sampled. Dietary levels of cetoleic (C22:1ω11), eicosapentaenoic (EPA, C20:5ω3), and docosahexaenoic (DHA, C22:6ω3) acids were 0.4, 0.3, and 0.5% in the fat of the LA diet, and 7.6, 4.2 and 4.3% in the FO diet, respectively. In the FO diet, EPA and DHA accumulated especially in the liver and heart, while cetoleic acid showed the highest affinity to the heart muscle and subcutaneous fat. The highest levels of EPA were found in raccoon dogs and polecats fed the FO diet. The mean EPA levels ranged from 6.7-9.3% in the liver fat and 7.2-8.0% in the heart muscle fat. In the mink, the corresponding values were 2.7% and 3.9%, respectively. DHA levels were the highest in the liver fat of the polecats, being 18.5% in the FO diet. In addition, the liver in raccoon dogs fed the FO diet (13.8%) differed significantly from themink (9.4%). The differences in the accumulation of these long-chained marine fatty acids were apparently caused by species differences in the efficiency of their peroxisomal β-oxidation.

Sheep Production

In sheep production the ability of the animal to retain and mobilize body fat reserves is of considerable importance in determining the sheep productivity or even its survival. The most common way to predict body fat reserves is the body condition score. On the other hand, it is accepted that breeds have a different fat distribution within the body (Taylor et al., 1989). In general, ewes breed for milk production tend to deposit more fat in internal depots and those breed for meat production deposit more fat in the carcass depot (Frutos et al., 1997). This kind of fat distribution can explain the use of an objective and more precise way to predict the internal fat in ewes of the Churra breed, in which the internal fat depots plays an important role. Thus, it is reasonable hypothesize that the internal fat depots are related with muscle and subcutaneous fat measurements. As a result, the study herein reported was undertaken to achieve the relationship between real time ultrasound measurements obtain over thoracic, lumbar and sternum regions to predict the internal fat depots of Churra da Terra Quente (CTQ) milk breed.

Nutritional Adequacy

When larvae of the parasitic fly Agria affinis (Fallén) were reared on fatty acid free diets, the characteristically high palmitoleic acid content of the body fats was much increased. Oleic acid in the diet was effective in reducing this, but not so effective as a mixture of fatty acids. The body fats still contained unusually high proportions of palmitic, palmitoleic, and oleic acids even when a mixture of fatty acids was fed. These observations are related to earlier observations on the nutritional adequacy of various fatty acids.

Terrestrial Insects

The body fat of the midge, Tanytarsus lewisi (Chironomidae), has been analysed, and has been found to contain major amounts of polyethenoid fatty acids normally associated with the fat of fish. It is interesting to note that this insect does all its feeding while in the larval stage on the bed of the river, under water, and that the body fat resembles that of algae, and plankton, which probably are the main sources of food, and differs considerably from the composition of most terrestrial insects hitherto recorded.

Tissue Tumour

Subcutaneous body fat is a distinct anatomical entity with unique physiology, metabolism, and disease. The main roles of fat are energy storage, hormone production, and insulation. Free fatty acids and glycerol can be assembled into triglycerides, and conversely triglycerides can undergo lipolysis. Insulin is the key hormone that controls this fine balance. Pregnancy is associated with increased truncal body fat and breast ptosis. Cellulite is the padded appearance of fat and there is currently no single proven treatment. Lipomas are the most common soft tissue tumour and can be treated with excision or liposuction. Lipodystrophies are disorders characterized by the selective loss of body fat and lipofilling is a useful treatment modality. Panniculitis is the inflammation of subcutaneous fat and treatment involves dealing with the precipitating cause. The plastic surgeon should be familiar with the anatomy, physiology, and pathology of fat in order to treat this wide array of adipose-related conditions.

DOI: http://dx.doi.org/10.5007/1980-0037.2017v19n4p459 Physical exercise is one of the forms of prevention and treatment of obesity and associated diseases such as hepatic steatosis. The aim of this study was to analyze whether hepatic steatosis interferes in the effect of physical exercise on the body composition of obese children and adolescents. The sample consists of 40 obese individuals, 13 children (8.17±1.33 years) and 27 adolescents (12.28±1.36 years). Total and segmental body composition was estimated by DEXA. Anthropometric measurements were performed, as well as ultrasound examination of the liver to measure intra-abdominal and subcutaneous fat, and to diagnose hepatic steatosis (HS). The intervention consisted of 20 weeks, with recreational/competitive activities being applied to children and, for adolescents, concurrent training (aerobic and resistance). The Levene’s, repeated-measures ANOVA and effect size tests (ES) by Eta-Squared were performed. It was observed that, although not statistically significant, analyzing the effect size, physical activity in both children (body fat ES effect time= 0.210 and ES effect group= 0.208; fat mass ES effect group = 0.338; fat android ES effect Interaction= 0.267), and adolescents (intra-abdominal fat ES effect group = 0.230) regardless of whether or not HS was effective in reducing body fat. Therefore, exercise was effective in improving the body composition of obese children and adolescents, regardless of HS.

Practical Measurement

The reproductive performance of the sow may be associated with the amount of fat stored in the body and the rate at which fat may be depleted. As body fat represents the easily mobilisable reserves of energy, an accurate and practical measurement of fat content is crucial. King et al (1986) have shown that linear baekfat measurements are the best single predictors of body fat compared to any other indirect indices of body composition. However practical experience has also suggested that fat measurements over the tuber coxae of the ileum (hip bone) will also provide an assessment of the fat status of a sow although its relationship to back fat depth is uncertain. Furthermore ultrasound techniques have not been tested in commercial conditions and the effectiveness of normal commercial practice in maintaining body fat reserves has not been previously examined.The object of the investigation was to assess whether the fat status of the sow as determined by ultrasonic fat measurements at the P2 position (6.5 mm from the midline of the backbone at the last rib) and hip bone would give an objective assessment of the condition and performance of the sow. The effectiveness of normal commercial practice in maintaining herd condition was also assessed.

The Impact

This study evaluated the impact of nutritional status of Morada Nova sheep at lambing on the reproductive and productive performance and on the survival of lambs in early weaning system. Nineteen, Morada Nova sheep were assigned to two groups according to body condition score (BCS) at lambing: low BCS (n = 11) and high BCS (n=8) with body condition respectively of (mean ± SD) 2.0 ± 0.3 e 2.9 ± 0.1. From birth until lamb weaning (45 days), sheep were weighed weekly and checked the BCS, loin subcutaneous fat thickness, loin depth, hematological profile, milk composition and production, and every three days, we measured the uterine diameter. Lamb weightings were performed up to one week after weaning (52 days). The lower availability of muscle and fat reserves in the low BCS group negatively affected milk production and consequently performance of suckling lambs. However, the results indicated that the uterine involution process, the reproductive parameters including prolificacy, rate of multiple births, number of white blood cells, milk quality, body weight of lambs at birth and mortality rates were not affected by the body condition. The results allowed to describe the responsiveness to opposite nutritional status of Morada Nova sheep, showing their characteristics of adaptation.

ABSTRACTBody condition score, assessed subjectively on the live animal, was related to the directly determined body composition of 73 mature, non-pregnant, non-lactating cows of Hereford × Friesian, Blue-Grey, Galloway, Luing and British Friesian genotypes. Relationships between condition score and chemically determined body fat were all very highly significant, and considered to be of value for predictive purposes. Differences between genotypes in the proportion of fat stored in the main depots of the body resulted in differences in the relationship between condition score and body fat. British Friesian cows had a higher proportion of their fat in the intra-abdominal depots and the lowest proportion of subcutaneous fat, resulting in their being fatter at any given condition score. Hereford × Friesian cows had the highest proportion of subcutaneous fat and were thus the least fat at any condition score. One unit change in condition score was associated with a change of 2242 (s.e. 103) MJ of body tissue energy in Hereford × Friesian, Blue-Grey, Galloway and Luing cows and 3478 (s.e. 392) MJ in British Friesian cows. These figures may be used to bring a greater degree of precision to the nutritional management of beef and dairy cows.

ABSTRACTNinety-two British Friesians and 62 Jersey castrated male cattle were slaughtered serially in five age groups at 13, 89, 170, 339 and 507 days, and dissected fully into lean, bone, intermuscular fat, subcutaneous fat, perirenal-retroperitoneal fat (kidney knob and channel fat), omental fat and mesenteric fat. The aim was to investigate the partition of body fat in these dairy breeds and the role of the partition of fat in determining carcass value.Relative to live weight, Friesians had more lean, subcutaneous fat and carcass fat (subcutaneous and intermuscular) at most ages, and Jerseys had more kidney knob and channel fat, and intra-abdominal fat. Friesians had a higher killing-out proportion and lean:bone ratio, and thicker subcutaneous fat.The order of increasing relative growth of fat depots with total body fat as the independent variable was, for Friesians: intermuscular < mesenteric < kidney knob and channel fat < subcutaneous < omental. In Jerseys the order was: intermuscular < mesenteric < subcutaneous < kidney knob and channel fat < omental. There were only small breed differences in the distribution of subcutaneous fat between eight regions. t I is suggested that, between breeds, there is a physiological link between the capacity for milk-fat production and the partition of fat within the body, with relatively high milk-fat producers depositing proportionately more fat intra-abdominally.Since the timing of slaughter is often determined by level of external finish in beef production, the breed difference in the partition of fat, which caused Jerseys to have a higher proportion of kidney knob and channel fat, and intermuscular fat, at the same proportion of subcutaneous fat, would reduce carcass value in Jerseys compared with Friesians.
