Interazioni tra animali selvatici e suini domestici allo stato brado in un allevamento biologico nella Sila Grande
No full textFree ranging farming systems present several positive aspects; however, there can be some negative effects, due to the natural factors to which the animals are exposed (e.g. possible interactions with wild animal species), that may have detrimental effects both on animal welfare and farm economics, and on the genetic of wild and domestic species. We analysed the interactions between a group of free ranging domestic pigs and wild animals (wild boar and predators) living in the same area. We verified the occurrence of spatial overlap between wild and domestic animals, especially between pigs and predators during the pigs birth season. Spatial overlap between pigs and predators jeopardises animal welfare: in fact, predation was the main responsible for piglets mortality. Genetic issues are raised by the spatial overlap and by the lack of breeding control, which lead to the presence of hybrids (wild boar x domestic pig, and vice versa) and of mixed breed pigs, which prevent the use of quality labels based on breed certification. All these aspects are detrimental to the farm economy
Welfare issues of modern laying hen farming
No full textThis review starts with a brief outline of poultry behaviour and biology and a description of the present laying hen farming situation in Italy. Moreover, it points out the situation of EU legislation currently in effect for laying hen welfare. It then reviews the main welfare issues of layer farming. The following aspects are considered: rearing system (e.g. stocking density, light intensity and photoperiod, equipment and facilities) and some health aspects. All these aspects represent important issues for farmed species, but special attention should be paid when we deal with intensively farmed species like poultry, where a lot of potential stressors may impair the welfare with consequences on health and production. The adoption of suitable housing systems and of adequate management techniques, as well as the presence of well trained stockpersons with a sound knowledge of poultry physiology and behaviour, are particularly important in guaranteeing a sufficient welfare level to poultry. Therefore, the adoption of specific codes of recommendations is highly desirable

No full textThe Animal Welfare Indicators (AWIN) project meets the stakeholders to ensure the acceptability of on-farm turkey welfare assessment
No full textThe overall goal of the AWIN project is to improve animal welfare by developing , integrating and disseminating information about animal welfare indicators.
The research objectives to be carried out in 4 Workpackages will focus on sheep, goats, horses, donkeys and turkeys .
The WP1 aims to develop and refine welfare assessment protocols and optimize ways to integrate them in the production chain. Moreover , WP1 aims to develop a protocol to use epidemiological data collected at slaughterhouse and or health information to identify challenges to animal welfare.
A turkey expert group decided to focus on the development of indicators for intensive systems for growing turkeys. Moreover they decided that the birds should be evaluated 2 to 3 weeks before slaughter. With regard to the gender , which should be used for the evaluation of the turkey welfare , the experts agreed to consider both males and females in the evaluation. The reason for it was lack of clear evidence indicating in which of the genders the welfare problems would be more significant. The turkey group proposes a two-step action: a first step at the slaughterhouse and the second on commercial farms .
STEP 1:
The choice of the appropriated number of flocks would be done at the slaughterhouse according to the characteristic of turkey's industries in each participating country. From each observed flock the following data will be collected: death on arrival, carcass weight, breast burns, footpad lesions, condemnations /down-grading information. The distribution of the collected data from the slaughterhouse evaluation will indicate the number of farms to be chosen as the extremes of the curve: the best farms (less death on arrival carcass weight-breast burns-footpad lesions-condemnations/down-grading) and the worst one.
STEP 2:
Many indicators found in the literature were considered and discussed by the turkey expert, as well as the implementation of the prototype with such
indicators in practical conditions on turkey farms. In addition most of such indicators were never tested far validity , feasibility and reliability. The turkey group decided to take an innovative approach of on farm evaluations, which could be feasible, well accepted by the farmers (understandable and including no animal handling), less time consuming than previous examples, but at the same time effective strict and objective as the previous developed protocols that demand massive amounts of time.
The turkey group members carne to a consensus in using a transect approach far the on farm evaluations . Turkey flocks are comprised of several thousand birds that, like other meat poultry, may vary tremendously on their welfare level. The choice of assessing the effectiveness of the transect methodology far on farm application, was based primarily on the potential of this methodology to be a valid, effective, and precise to provide a reliable evaluation of critical welfare issues common in meat poultry such as the incidence of leg problems, immobility and injuries.
The line transect methodology has successfully used in wildlife studies far decades. Far animal welfare assessment it is applied as divided walking paths covering the full area of the production house. The procedure is to a certain extend similar to the daily farm animal care routine. Depending on the width of the house , the production area is divided in around 2.5 m wide bands limited by the walls, feeder and drinker lines, creating invisible birds movement barriers. Transects are performed in random order alternately in both directions . The observers walk slowly recording in a tablet all incidences of following validated welfare indicators: immobile, limping, dirty, sick, agonizing and dead, all clearly identifiable during data collection. Percentage of incidence of each condition per transect is calculated by dividing the total population size by the number of transects, assuming a random bird distribution . This procedure is envisioned as a general assessment procedure far the most common welfare issues in meat poultry and as a practical tool far management purposes.
