These characteristics were determined on Longissimus thoracis samples taken from 40 entire donkey males of Martina Franca breed slaughtered at 12 (Group 1, n = 20) and at 18 months (Group 2, n = 20) of age. Tenderness was evaluated at two and seven days post slaughter using a Warner-Bratzler shear force device. The chemical composition showed a signifycant increase in protein content (P < 0.05) in the meat of donkeys slaughtered at 18 months of age (22.3 g/100g) compared to the meat of younger animals (21.4 g/100g). Intramuscular fat content was significantly lower (P < 0.05) in Group 1 (2.41 g/100g) compared to Group 2 (3.71 g/100g). Shear force values at seven days post slaughter were significantly (P < 0.01) lower ((5.15 ± 0.31) kg/cm 2 ) in Group 1 compared with the results obtained at two days post slaughter ((6.25 ± 0.53) kg/cm 2 ). In Group 2 shear force values obtained seven days post mortem were higher ((5.88 ± 0.23) kg/cm 2 ) compared with Group 1 after the same ageing period but significantly (P < 0.05) lower if compared with those ((6.53 ± 0.23) kg/cm 2 ) determined in the same animals two days post slaugher.

These molecules, are receiving attention from a nutraceutical point of view because of their potential direct role in regulating metabolism and infant body condition. Donkey's milk may be considered a good replacer for cow's milk in feeding children with severe Ig-E mediated cow's milk protein allergy, due to its high similarity with human milk. In this study, the presence of cytidine, uridine, CMP, UMP, guanosine, and adenosine, involved in numerous biochemical and physiological activities, were detected for the first time through a RP-HPLC method.

Cow's milk protein allergy (CMPA) is an abnormal immunological response to cow milk proteins,... more Cow's milk protein allergy (CMPA) is an abnormal immunological response to cow milk proteins, which results in IgE-mediated reactions. The therapeutic strategy to respond to CMPA envisages the total elimination of milk or the administration of cow's milk substitutes. For this reason the use of milk from other mammalian species was tested. Among them, donkey's milk proved to be the best alternative in feeding infants affected by CMPA, since its chemical composition is comparable to human milk. In this work an in vitrostudy was performed in order to analyze the IgE reactivity to milk protein allergens from cow, donkey and goat. In particular, immunoblotting experiments using sera from milk-allergic and non-allergic adult volunteers were conducted with the aim of verifying the hypoallergenic property of donkey's milk. This study provided a preliminary evidence of the hypoallergenicity of donkey's milk when compared to bovine and goat milk. Considering the obtained r...

Twenty entire male lambs had been used in this experiment; the Longissimus Thoracis et Lumborum muscle, taken from all the 20 animals, was analyzed for chemical composition, fatty acid, cholesterol and mineral contents. Protein content was 22.1%, fat content 4.5%, cholesterol 63.5 mg/100 g. The most represented fatty acid was oleic acid (37.62% of total fatty acids), followed by palmitic acid (26.31% of total fatty acids). Phosphorus and potassium were the two most represented minerals in muscles examined, respectively 285.6 and 329.5 mg/ 100 g. The results of this study demonstrated the good quality of the meat obtained by a local ovine breed slaughtered at higher final body weight when compared with the most common suckling lambs normally commercialized in Italy.
