No full textEffects of protein sources on performance, carcass composition, blood parameters and meat quality in Charolais heifers
No full textThe aim of the present study was to evaluate the effects of feeding faba bean and sweet lupin as alternative protein sources to soybean on productive performance, blood parameters, carcass composition, and chemical-physical characteristics of meat and its fatty acid (FA) profile in Charolais heifers. Twenty-four heifers were divided into three homogenous groups and fed with durum wheat straw and three iso-energetic and isonitrogenous pelleted complete diets containing 14% (on as-fed basis) soybean meal; 28% faba bean; and 20% sweet lupin seed. The animals were slaughtered after a 168 day feeding period, and the Longissimus lumborum muscle was sampled for meat quality measurements. The feed conversion index was better in the heifers fed faba bean compared with the soybean treatment group (6.71 versus 7.17). No differences were found among treatment groups in productive performance, slaughtering data and physical features. The concentration of linoleic acid in the meat of the soybean group differed significantly from that in the lupin group (2.38 versus 2.11%). Feeding lupin seed increased the concentrations of C20:3 n-6 (0.09%) and C20:4 n-6 (0.20%) in meat significantly, compared with the soya- and faba bean treatments (0.06-0.07% and 0.12-0.13%, respectively). No differences were found among groups for blood parameters, except for urea concentration, which was lower in the lupin group compared with the concentrations in the serum of heifers receiving the soya bean treatment (31.29 as opposed to 37.56 mg/dL). In conclusion, since faba bean and lupin seed did not affect any of the parameters negatively, these legume grains can be included successfully as alternative protein sources in beef cattle diet

No full textEffects of dietary extruded linseed (Linum usitatissimum L.) on performance and meat quality in Podolian young bulls
No full textThis study compared effects of a diet containing 3% extruded linseed (EL) (Linum usitatissimum L.) with a control diet (C) on growth, carcass traits, and meat quality in young Podolian bulls. After 208 days on feed, the bulls were slaughtered at 18 months of age. Samples of Longissimus lumborum (LI) were analysed to assess their physical and chemical parameters and intramuscular fatty acid composition. Average daily gain, feed intake and feed efficiency were not affected by treatments. Bulls fed EL (n = 6) had significantly greater final (612 kg versus 593 kg) and slaughter weights (583 kg versus 563 kg) than those fed C (n = 6). Compared with C, EL significantly increased percentages of lean from the pelvic limb (71.9% versus 69.3%) and of bone from the lumbar region (30.0 versus 27.1%). Meat pH recorded at slaughter was significantly greater for C than EL (6.7 versus 6.4). Diet did not affect meat colour, chemical composition and shear force of either the raw or cooked meat. Total amounts of saturated, monounsaturated and polyunsaturated fatty acids were not influenced by the diets. Concentrations of linoleic acid (C18:2 n-6) (3.30 versus 4.08) and total n-6 fatty acids (3.83 versus 4.73) were reduced by EL, while EL significantly enhanced linolenic acid (C18:3 n-3) (0.45 vs 0.20) and total n-3 fatty acids (1.64 versus 1.18) in the meat compared with C. Thus, dietary supplementation with 3% EL improved the amount of n-3 fatty acids in the meat from young Podolian bulls without affecting their performance
Effect of an extruded linseed diet on meat quality traits in Nero Lucano pigs
No full textThe study aimed to evaluate the effect of a diet containing extruded linseed (Linum usitatissimum L.) on growth performances, carcass traits and meat quality in Nero Lucano pigs. Sixteen male piglets were weaned at about 50 days of age and divided into two homogeneous groups fed a control diet (C) or a diet containing 3% extruded linseed (EL). The trial lasted 32 weeks and pigs were slaughtered at 9 months of age. Samples from the Longissimus dorsi (Ld) muscle were analysed to assess physical and chemical parameters and intramuscular fatty acid composition. Average daily gain, feed intake and feed conversion ratio were not affected by the diet. Pigs fed the C diet showed a significantly greater slaughter weight in comparison to the EL group (116.50 vs 108.25 kg) Meat pH and chemical composition were not influenced by the diet. No differences were found for shear force (WBS) in raw meat, while cooked meat of the EL group showed a lower WBS value. The EL diet significantly lowered total SFA and increased total PUFA, of both n-6 and n-3 series. Among the n-6, significant differences between dietary treatments were found for linoleic acid. As for the n-3 series, EL feeding significantly enhanced linolenic acid, EPA, DPA and DHA. Feeding EL also significantly lowered the PUFA/SFA and n-6/n-3 ratios and the AI and TI, with benefits for human health. In conclusion, dietary supplementation with 3% EL didn't affect growth performance while it improved the fatty acid profile of meat

No full textNational survey on training and clinical practice of the Pneumologist in Respiratory Intensive Care
No full textBackground. Despite the expansion of respiratory intensivology (IR) in the last 15 years in Italy, there are so far no data concerning the training and the clinical activity of the pneumologist in IR. Aim. To analyse with a survey the training and the clinical practice of the pneumologist in IR. Methods. The survey was performed in 2007 via web by sending a 26-items questionnaire to the 315 pneumologists belonging to the AIPO Study Group of Respiratory Intensive Care. Results. The rate of response to the questionnaire was of 81.9%. 215 pneumologists (68.3%) with a stated interest for IR (male gender: 87%; age > 35 years: 94.3%; belonging to Hospital Pulmonology: 69.4%) were included into the study. Training in IR during the university specialty was believed insufficient in 97.3% of cases. For each of the 8 considered IR activities, training occurred more often in the working environment (range: 21.7-74.0%) than during the university specialty (range: 1.4-38.4%), with a length 50% cases, utility of guidelines and need for considering the majority of IR activities as part of the clinical store of the pneumologist was declared. In 96.6% of cases, Respiratory Intensive Care Unit was considered as the setting where to perform noninvasive ventilation. The autonomy in performing IR activities in the clinical practice turns out to be heterogeneous (range: 2.9-94.3%) with values > 70% only for fiberoptic bronchoscopy, cardio-pulmonary resuscitation, noninvasive monitoring and noninvasive ventilation. Conclusions. From this survey for the pneumologist emerged the existence of a gap between the importance to have IR within his own clinical store and the inadequacy of the university training received. It is required to improve the training of the pneumologist to give him/her the instruments needed for the clinical management of the respiratory critical patient
