This Research Paper aimed to investigate donkey welfare in dairy husbandry systems and to identify the potential factors affecting it at animal level. In 2015, twelve dairy donkey farms (19-170 donkeys per farm, mean = 55 +/- 48), distributed throughout Italy, were visited. On each farm, the Animal Welfare Indicators (AWIN) welfare assessment protocol for donkeys was used by two trained assessors to evaluate the welfare of animals for a total of 257 donkeys assessed. The protocol includes animal-based indicators that were entered in a digitalised system. Prevalence of different scores at individual, farm and category level were calculated. Farmers were asked to fill out a questionnaire including information regarding the management of donkeys and their final destination. Answers to the questionnaire were then considered as effects in the risk factor analysis whereas the scores of the animal-based indicators were considered as response variables. Most of the donkeys (802%) enjoyed a good nutritional status (BCS = 3). 187% of donkeys showed signs of hoof neglect such as overgrowth and/or incorrect trimming (Min = 0% Max = 545%). Belonging to a given farm or production group influenced many of the welfare indicators. The absence of pasture affected the likelihood of having skin lesions, alopecia, low BCS scores and a less positive emotional state. Lack of routine veterinary visits (P < 0001) and having neglected hooves (P < 0001) affected the likelihood of being thin (BCS < 3). Belonging to specific production groups, lack of access to pasture and showing an avoidance reaction to an approaching human (AD) resulted in risk factors associated with a higher prevalence of signs of hoof neglect. Our results support the idea that lack of knowledge of proper donkey care among owners was behind many welfare issues found.

Although camelina [Camelina sativa (L.) Crantz] is a good source of protein, antioxidants, and polyunsaturated fatty acids, its antinutritional compounds limit its use in animal feeding. The aim of this study was to verify the effect of feeding laying hens with up to 20% of camelina cake from a breeding line containing a low level of glucosinolates on performance, welfare, and eggshell quality. Two hundred and forty Hy-Line® hens from 18 to 51 weeks of age were divided into three treatments: control (C), camelina cake 10% (CAM10), and camelina cake 20% (CAM20). Egg number was recorded daily, while egg weight, feed consumption, and mortality were recorded weekly. At 24 and 43 weeks of hen age, shell resistance to fracture was measured. Our results demonstrate no detrimental effects for CAM10 and CAM20 diets on feed intake, growth performance, and welfare. No difference in egg production was detected among the diets. The significant (p < 0.05) interaction of diet and age factors suggest that the addition of camelina cake, up to 20%, likely protects the eggshell of older hens. Our findings confirm that camelina cake might be an alternative and sustainable protein source for hens.

Heterophil to lymphocyte ratio, plasma corticosterone and tonic immobility test, plumage and leg score (Food Pad Dermatitis, FPD) are frequently used as indicators of welfare in chickens. Three traditional Italian chicken breeds (60 birds/group) were studied: Valdarnese Bianca (VB), Bionda Piemontese (BP) and Robusta Maculata (RM). At 80 days of age, reactivity was tested through Tonic Immobility (TI) and plumage and leg score tests. Immediately after phenotypical and behavioural tests, the blood samples were collected from the ulnar vein of chickens. TI duration was not significant among the breeds (VB 72.2 ± 8.3 s; BP 95.2 ± 9.0 s; RM 76.5 ± 8.6 s; mean ± SEM). RM and BP needed a mean number of induction significantly higher than VB (RM = 1.84 ± 0.1; BP = 1.96 ± 0.1; VB = 1.38 ± 0.1; p < 0.0001). The highest corticosterone mean concentration (3.4 ± 0.23 ng/mL) was found in the VB breed, whereas the lowest (1.71 ± 0.21 ng/mL) was found in BP birds. The heterophil to lymphocyte (H/L) ratio was significantly (p < 0.0001) higher in the VB breed (0.86 ± 0.03) than BP (0.78 ± 0.02) and RM (0.75 ± 0.03). In all birds neither plumage damages nor FPD were found. In conclusion, the three breeds showed the typical reactivity of rural breeds adapted to alternative and organic rearing systems; the anti-predatory response, the plasma corticosterone concentration and the H/L ratio could be considered a positive adaptation indicator.

In organic farms, hens can freely access the outdoor areas, a potential source of helminth infections. This study aimed to evaluate the effective use of free-range access in organic laying hen’s farms located in Italy. The other objective was to quantify the major risk factors for endo- and ectoparasite infestation and its effect on performance, health and welfare, correlated to the use of free-range access. Fifteen organic farms of laying hens were assessed and visited twice. The total number of hens in the three zones was counted and recorded three times daily. Indirect indicators (characteristics of vegetation cover, amount and weight of droppings) were recorded. To evaluate parasite infestation, 15 fresh faecal samples per flock were collected from the ground/floor or perches. From seven farms, 15 gastrointestinal tracts from end-of-lay hens were qualitatively and quantitatively examined for the presence of endoparasites at different developmental stages. The percentage of hens observed outdoors in zone 3 was affected by free-range features. As expected, zone 1 was more frequented by hens than the others. The correlations among number and weight of droppings collected outside, vegetation score and the percentage of hens showed interesting results. Only three species of parasites were found during faecal samples analysis. There was a significantly and positively correlation between the number of Capillaria and Ascaridia eggs. The results showed that the presence in the free-range area of mounds, trees and bushes attracted more animals outside and allowed them to show their natural behaviour.

Welfare of animals significantly depends on how stakeholders perceive their needs and behave in a way to favor production systems that promote better welfare outcomes. This study aimed at investigating stakeholders’ perception of the welfare of equines, small ruminants, and turkeys using text mining analysis. A survey composed by open-ended questions referring to different aspects of animal welfare was carried out. Text mining analysis was performed. A total of 270 surveys were filled out (horses = 122, sheep = 81, goats = 36, turkeys = 18, donkeys = 13). The respondents (41% veterinarians) came from 32 different countries. To describe welfare requirements, the words “feeding” and “water” were the most frequently used in all the species, meaning that respondents considered the welfare principle “good feeding” as the most relevant. The word “environment” was considered particularly important for turkeys, as well as the word “dry”, never mentioned for other species. Horses stakeholders also considered “exercise” and “proper training” important. Goat stakeholders’ concerns are often expressed by the word “space”, probably because goats are often intensively managed in industrialized countries. Although the sample was too small to be representative, text mining analysis seems to be a promising method to investigate stakeholders’ perception of animal welfare, as it emphasizes their real perception, without the constraints deriving by close-ended questions.
