Texto completoOptimal animal nutrition allows adequate productive performance and correct welfare conditions of livestock species; moreover, it ensures animal’s products with high-quality characteristics that meet safety and security requirements for the consumers and guarantees a suitable nutritional value. In this context, the application of nutritional strategies, including the supplementation of additives, used to improve feed nutrition, may play a significant role in livestock production; it also represents an important issue in the regulatory framework of the European Union. In this paper, four in vivo trials are presented to evaluate the dietary effects on the quali-quantitative performance of broiler chickens and pigs. In particular, the use of synthetic emulsifiers, a polyphenols-enriched olive pulp extract and a probiotic was considered in the whole production cycle of broiler chicken. Whereas, the polyphenol-enriched olive pulp extract was added in the diet of sows and piglets to investigate the positive effects of this supplementation in two critical moments of the productive system of this species: the peripartum of the sows and the weaning of piglets. In the first experimental trial, a total of 1200 one-day-old ROSS 308 broiler chicks were assigned to four experimental groups consisting of 15 pens with 25 birds per pen. A 2×2 factorial design was applied to compare the different dietary treatments [control diet (CTR) or diet supplemented with AVI-MUL TOP (AMT) at 1g/kg from d 0 to 12, 0.75g/kg from d 12 to 22 and 0.5g/kg from d 22 to 44] and gender. Growth performance (BW, ADG, FI and FCR) were determined on days 0, 12, 22, 37 and 44 for males. One female chick (day 37) and one male chick (day 44) from each pen were chosen on BW basis and slaughtered to collect blood, liver samples and caecum content and to determine the dressing and breast muscle percentages. AMT supplementation increased BW on day 12 (P=0.02), ADG from day 0 to 12 (P<0.05), ADFI from day 12 to 22 (P=0.06). Moreover AMT supplementation reduced FCR from days 0 to 44 (P<0.05) in males. Dietary AMT significantly increased the b* index (yellowness) (P<0.01) and reduced cooking loss (P=0.03). The emulsifier also increased plasma cholesterol, HDL and LDL content compared to the control (P<0.01, P=0.02, P<0.01, respectively), while no significant differences were observed on intestinal microbial flora among treatments. The expression of Apo A-I and Apo B lipid metabolism related genes was evaluated from the liver samples and a significant up regulation (P=0.0056) of the Apo B gene was found in AMT females chicks. In conclusion, the supplementation of AMT may have a beneficial effect on the growth performance, lipid metabolism and meat quality of broiler chicks. The second experimental trial evaluated the dietary effects of a polyphenol-enriched olive pulp extract on 720 one-day old ROSS 308 female chicks, equally assigned to four experimental groups consisting of 12 pens and 20 animals each. The dietary treatments were control diets (CTR) or diet supplemented with 200 IU/kg of vitamin E (T1), 1 and 5 g/kg of Ethifenol (T2 and T3, respectively). The substance in exam had a total polyphenols concentration of 25mg/g. Growth performance (BW, ADG, FI and FCR) were determined on days 0, 10, 20 and 35. At the end of the trial, one female chick was chosen from each pen on BW basis and slaughtered to collect blood, liver samples and caecum content and to determine the dressing and breast muscle percentages. The supplementation of the olive pulp extract did not show any significant differences (P>0.05) on the growth parameters and caecum microbiological analysis among the groups; while the dietary supplementation significantly improved the b* index (yellowness) of animal skin (P=0.003). The extraction and quantification of total polyphenols and the expression of some lipid metabolism related genes (PPARα, ATGL, ACACA, CPT-1, ACOX and FASN) were performed from hepatic samples. The hepatic concentration of phenolic compounds did not show any statistical differences (P>0.05) among the groups, although it reflects the supplementation level. No statistical differences were also found in the gene expression. In conclusion, the olive pulp extract showed minor benefits on the growth performances, which however appear interesting considering the short production cycle of these animals. The third experimental trial was divided into two phases to investigated the effects of the polyphenolsenriched olive pulp extract supplementation on the performance of sows and piglets. During phase 1, 18 multiparous sows, homogeneous by age and birth order, were assigned to two experimental groups of 9 animals each. The dietary treatment were control diet (C) or diet supplemented with 1.25kg/ton of olive pulp extract (T). The compound of interest was added to the diet for a period of about 40 days (from two weeks before the expected date of birth to the end of lactation). Body condition and reproductive parameters were analyzed and colostrum samples were collected to determine the total polyphenols concentration and the antioxidant activity. In phase 2, 180 newborn piglets, homogeneous by body weight, were assigned to four experimental groups consisting of 45 animals and 9 replicates each. The Ctr-Ctr piglets were born from control sows and did not receive the extract, the Ctr-T group was composed by control sow’s piglets who received the compound; the T-Ctr piglets group was born from treated sows and they did not receive the olive pulp extract and the T-T group was composed by treated sow’s piglets who received the extract. Phase 2 was divided into two periods (prestarter from d 0 to 14 and starter from d 15 to 42) and dietary treatments were control diet (Ctr) and diet supplemented with 5.0 and 2.5kg/ton of olive pulp extract (T) in the first and second period, respectively. Growth performance (BW, ADG, FI and FCR) were determined on days 0, 14 and 42. The supplementation did not show any significant differences (P>0.05) in phase 1; however, it was observed that the body condition and reproductive parameters of the treated animals were higher than the control group. The antioxidant activity of T sows was statistically higher (P=0.05), although the total polyphenol concentrations did not show significant variations (P>0.05) between the two groups. In phase 2, the T-Ctr group showed higher body weight at day 42 (P=0.03) and higher ADG during the second period (14-42d) and overall (0-42d) (P=0.03 and P=0.05, respectively) compared to the other groups. Moreover, FCR, carcass yield and transformation yield of the T-Ctr group were statistically significant (P≤0.01) compared to the other experimental groups. In conclusion, the supplementation of the compound of interest showed the best results on the piglets’ performance, underlining the importance of milk as a vehicle of functional substances and suggesting possible beneficial effects on the general health conditions. In the fourth experimental trial, a total of 960 one-day-old ROSS 308 male broiler chicks were assigned to four experimental groups consisting of 12 pens with 20 animals per pen.The dietary treatments were control diet (CTR) and diet supplemented with 600, 400 and 200g/t of METALACT (T1, T2 and T3, respectively). The probiotic additive was composed by a mixture of Lactobacillus pharmacimis and L. rhamnosus and supplemented for a period of 48 days. Growth performance (BW, ADG, FI and FCR) were determined on days 0, 11, 22 and 48. At the end of the trial, one chick from each pen was chosen on BW basis and slaughtered to determine the dressing and breast muscle percentages. The METALACT supplementation did not showed any significant differences (P>0.05) on the growth parameters investigated. In conclusion, the probiotic did not modify the growth performance, but it is not possible to exclude possible beneficial effects on modulation of the microbial intestinal flora and on the qualitative properties of the meat. The overall results showed that the dietary supplementation of beneficial substances is not only able to significantly modify the animal’s growth performance and the quality of the products, but it is also able to improve the general welfare conditions and the intestinal balance of the livestock species.

Texto completoThe object of the research is based on the assumption that if a food is endowed with origin, authenticity and quality, it assumes for the consumer a market value much higher than a conventional product, that such signs cannot be transmitted either directly or indirectly through the packaging or advertising. The work developed through the consultation of International, European, National standards sources for the protection of food products, to identify the legal instrument of valorization suitable to the case of the “pane di Cerchiara”, in consideration of the contingents starting conditions of the product and of the context of the production. Once identified the reference sources, the research has focused on the instrument considered most appropriate to the valorization of the product bread, namely the “ marchio collettivo geografico” regulated mainly by the Code of Industrial Property for which: “un marchio collettivo può consistere in segni o indicazioni nel commercio possono servire per designare la provenienza geografica di prodotti o servizi”. This instrument is the most suitable to defend in time the product characteristics and safeguard the essence of attempts to vulgarization or use of the name by operators of food from other geographical areas, other than the area of Cerchiara and therefore devoid of that characterizing technical-cultural “quid”, inherited from a deep tradition suitable to give to the finished product unique characteristics. With the goal of a concrete realization of a distinctive sign of the alimentary product the trademark “pane di Cerchiara a lievito madre”, the activity then continued with the drafting and administering to all the bakers of the municipality concerned of a “historical questionnaire” and a “technical sheet” for the collection of the data on raw materials used, the recipes, the cooking methods and the baking techniques. Afterwards from the bakers, were collected a series of samples of all the raw materials used in the production, processing and preparation, for implementing the phase of the technical-scientific characterization of the product through an elaborate protocol of analytic investigations. The data obtained in the characterization phase, has been propaedeutic and necessary for the drafting of the production disciplinary and the regulations governing use of the trademark “pane di Cerchiara a lievito madre”, acts through which they prepare a system of rules, controls and the relevant penalties provided for by the Code of Industrial Property (ex art.11 del d.l.g. n30/2005) as a necessary condition for the verification of the admissibility of the application for the registration made by the Patent Office, not only in reference to the legality of the procedure, but also regarding the actual ability of the instruments predisposed to fulfill the intended purpose of the trademark. The trademark owner, has been identified in the Municipal Adminstration of Cerchiara di Calabria as the only institutional subject, in the social context, able to adequately represent the entire community linked to the territory of origin of the food product and be able to fulfill the function of guarantee required “ex lege” by the trademark holder, and that is ensured by a system of penalties, that punishes with the decadence, the inertia of the holder that does not control the proper use of the trademark by the users. In order to optimize the intrinsic relationship between the product and the territory and make use of the reputation of an area that already has a particular renown, it was decided to identify the legal name in the expression “pane di Cerchiara a lievito madre”, and have been developed a series of logo to match the trademark proposed to the municipality trademark holder, and the adherents bakers, until reaching the final registration of the trademark (n°CB 2014 C0035 del 07.05.2014), ultimately elaborating a tool that, also in terms of food security, stands as a guarantee for the final consumer that choosing a branded product, has the safety of consuming a food elaborated under a strict production regulations. The creation of a geographic collective mark with a strong territorial character, has ultimately pursued the aim of achieve a virtuos mechanism for an entire community and for a whole territory, aiming at increase its appeal, on the food market, environmental and of the tourism market, with the hope of providing a beginning of an enhancement of the entire geographic area of reference, worthy of a great future.
