“…This is associated with the fact that not all SFAs are hypercholesterolemic, and MUFAs exert a protective effect, likewise PUFAs. It is assumed that an AI value lower than 0.5 is beneficial for human health [84], although some authors recommend an atherogenicity index for animal lipids in the range from 0.5 to 1.0 [81,85]. In the present study, the values of AI of the organically and conventionally produced meat did not differ significantly.…”

The aim of the study was to assess the fatty acid profile and nutraceutical properties of lipids contained in fallow deer (Dama dama) meat produced in organic and conventional farming systems. Longissimus lumborum (LL) and semimembranosus (SM) muscles from 24 fallow deer carcasses were selected for the study. The fallow deer meat from the organic farming system was characterized by significantly lower intramuscular fat content. The fatty acid profile in the organic meat was characterized by a particularly high proportion (p < 0.0001) of conjugated linoleic acid—CLA (LL—2.29%, SM—2.14%), alpha-linolenic acid—ALA (LL—4.32%, SM—3.87%), and docosahexaenoic acid—DHA (LL—2.83%, SM—2.60%). The organic system had a beneficial effect (p < 0.0001) on the amount of polyunsaturated fatty acids (PUFAs), including n-3 PUFAs, which resulted in a more favorable n-6 PUFA (polyunsaturated fatty acid)/n-3 PUFA ratio. The significantly higher nutritional quality of organic meat lipids was confirmed by such nutraceutical indicators as the thrombogenic index (TI), ∆9-desaturase C16, elongase, and docosahexaenoic acid + eicosapentaenoic acid (DHA+EPA) in the LL and SM and cholesterol index (CI), and the cholesterol-saturated fat index (CSI) indices in the SM. LL was characterized by higher overall quality.

“…According to the relevant nutritional recommendations, the PUFA/SFA ratio in the human diet should be 0.4 or higher [55]. Some authors [81] suggest that this ratio should be in the range from ≥ 0.45 to 1.0. In the present study, these criteria were fulfilled only by the meat from the organically farmed fallow deer.…”

“…In the last years, the high interest in animal welfare, in the organic animal products, and the need of healthier diets in Western Country populations, led to more sustainable livestock systems. The rustic breed is more suitable for this purpose, and recent studies confirmed the Maremmana suitability to the extensive farming conditions (TOCCI & SARGENTINI, 2020).…”

“…From 15 to 24 months (fattening period) the fresh grass consumption, estimated comparing grazed areas with ungrazed areas, was on average 20.0 kg/head/day. In the same age range the concentrate supplementation is reported in TOCCI & SARGENTINI (2020). The chemical composition of pasture feed is in table 1.…”

This study evaluated the performance at slaughtering of calves; young bull and bull of Maremmana breed, and compared, through Analysis of Variance (ANOVA) and Principal Component Analysis (PCA) on fatty acid composition, the characteristics of the resulting meat categories: veal, young bull meat and bull meat. The Maremmana cattle is a local endangered breed deriving from Tuscany and Latium. The animals of this study were raised under same conditions in pasture with hay and concentrate supplementations. Eighteen calves of 12-14 months, 27 young bulls of 18 months and 14 bulls of 20-24 months were slaughtered in this trial. The performances at slaughtering were considered, and on the meat samples, the chemical analysis and the fatty acid composition were carried out. Results were submitted to ANOVA and PCA, and a Heat map that considered the fatty acid distances among meat typologies was built. Slaughtering performances were better in young bulls and bulls. Chemical composition didn’t differ among meat categories. Saturated fatty acids (SFA) were similar among meats, but Monounsaturated (MUFA) and Polyunsaturated fatty acids (PUFA) were lower in veal. Desirable fatty acids and Healthy Indices were better in veal. The results of PCA and Heat map confirmed that veal was quite different from other meats. Maremmana meat deriving from animals of different age has shown overall good characteristics, suitable for the diet of western country population.

We assessed the effects of inclusion of chickpea from 24 to 21%, as feed basis, in diets for organically reared bulls. Sixteen young bulls (270 ± 6.4 days of age; 246 ± 0.13 kg in weight) belonging to a native Italian breed (Maremmana) were randomly assigned to two dietary treatments. The control diets were based on mixed grass hay, maize meal, and barley meal. In the experimental diets, barley was equally substituted by locally produced chickpea. Animals were weighed every 2 weeks until the prefixed slaughtering weight (630 kg). Plasma metabolites were measured at the 1st, 7th, and 14th month of the experiment. Chemical composition, colour, shear force, and water holding capacity of meat were assessed on Longissimus thoracis et lumborum 7 days after slaughter. The chickpea-fed animals showed a significantly greater average daily gain (1064 vs. 1168 kg/day), a shorter growing phase (364 vs. 335 days), and a better carcass conformation. Plasma metabolites and meat quality were not influenced by the treatments. The better growth performance and carcass quality of the chickpea fed bulls resulted in a higher economic profit for the chickpea-based diets. Results suggest that chickpea may allow sustainable performance improvement of native breeds within their traditional farming systems.
