An overview about feeling analysis and also emotion recognition from wording

cated that supplementation with dietary SBO is beneficial in attenuating the concentration of odour-causing compounds and that it modulates the composition of caecal microbiota in broiler chickens.Intensive pig production systems are a source of stress, which is linked to reduced animal welfare and increased antimicrobial use. As the gatekeepers of the welfare of the animals under their care, farmers are seen as the stakeholder responsible for improving animal welfare. The aim of this study was to explore the knowledge and attitudes of pig farmers towards pig welfare and the impact of such attitudes on farmers' selection of management strategies on the farm. We conducted in-depth semi-structured interviews with 44 pig farmers in one of the main pig producing regions of Brazil. Interviews covered knowledge and attitudes towards pig sentience and behaviour and welfare-related issues commonly observed in intensive pig farms (belly-nosing, fights, tail-biting, diarrhoea and castration without pain control) and farmers' conception and attitudes towards pig welfare. We identified many management and animal-based indicators of poor welfare, such as the use of painful and stressful management practices and use among the participants. This suggests that farmers may not be sufficiently informed or engaged in responding to consumers' expectations and commitments made by companies, which can pose a severe economic risk for farmers. The findings of this study indicate that economic, technical and social factors restrict farmers' autonomy and their ability to perform their role as stewards of animal welfare. (Re)connecting different human, animal and environmental interests may be a step to changing this scenario.Silkworm (Bombyx mori L.) pupae are a by-product derived from silk production, which is often treated as waste and thus discarded this can cause serious environmental problems and a loss of nutrients. Avadomide manufacturer Silkworm pupae are a rich source of protein and lipids, and the resulting protein meal can provide promising outcomes as livestock feed, notably for monogastric species. However, one possible issue that needs to be considered is the possible implication of the 1-Deoxynojirimycin (1-DNJ), a bio-compound of the silkworm that impairs glucose absorption, in poultry nutrition. Therefore, the present study evaluated the effect of the dietary inclusion of full-fat or defatted silkworm pupa meal (SWM) on the apparent digestibility of nutrients, feed choice and faecal microbiome in meat-producing quails. For the digestibility trial, a total of thirty-three 27-day-old Japanese quails (Coturnix coturnix japonica) were individually housed in digestibility cages and received three experimental diets a control diet (control, thermoaerophilus and Bacillus thermoamylovorans (P  less then  0.01) scored higher in SWM-FULL quails than in SWM-DEF and Control treatments. The present study demonstrated that a successful dietary inclusion of SWM for fattening quails needs to overcome the digestive criticalities caused by the of presence specific bio-compounds, namely chitin and 1-DNJ.Dairy goats may rely heavily on body fat and protein reserves in early lactation. Therefore, we aimed to determine the energy requirement and estimate the efficiency of utilization the nutrients of tissues mobilized in the first 8 weeks of lactation for milk production using the comparative slaughter technique. The average initial body mass of 51 multiparous goats was 57.19 ± 8.38 kg and a body condition score of 3.0 ± 0.5. Three goats were slaughtered at the beginning of the experiment to serve as baseline animals to estimate initial empty BW and initial body composition. We used a complete randomized design in which the factor was the day of lactation for slaughtering (the 7th, 14th, 21st, 28th, 35th, 42nd, 49th and 56th day), with six repeats, totalling 48 goats. No fasting before slaughtering. All animals received a single experimental diet. The efficiency of transferring energy from body reserves to milk was estimated using a multiple linear regression equation yielding a value of 0.76. The total energy stored in the empty body decreased over the eight lactation weeks, from 726.47 ± 26.19 to 316.18 ± 49.21 MJ, a 56.47% reduction, mainly because of a reduction in the energy from internal fat of 3.96 ± 1.98 MJ/day. In conclusion, the net energy required for maintenance is 60 ± 30 kJ/BW0.75 per day, and the net energy required for lactation decreases 70 ± 30 kJ/day during the first eight lactation weeks.Pre-slaughter transport exerts negative effects on broilers' welfare, meat yield, and meat quality, but little is known about the effect of transport on medium-growing broiler chickens. This study aimed at evaluating the effects of different durations of transport (0, 0.5, 1, 2, and 3h) on stress biomarkers and meat quality of medium-growing Yellow-feathered broiler chickens. One hundred and eighty Chinese Yellow-feathered broilers aged 75days (marketing age), of 2.02kg average BW, were allotted into five groups; each group contained six replicates (six birds/replicate (crate)). Each crate with dimensions 74×55×27cm (length × width × height) was loaded with six birds, that is, 30kg live BW/m2 crate. The tested transport durations increased BW loss (linear, P0.05), but total antioxidant capacity decreased (linear, P less then 0.01). The drip loss of breast muscle increased (linear, P less then 0.01), whereas shear force, pH at 24h postmortem, and breast meat color lightness (L*), redness (a*), and yellowness (b*) scores were not affected. In conclusion, the tested transport durations (from 0.5 to 3h) increased BW loss and some plasma stress biomarkers in 75-day-old Yellow-feathered broiler chickens, but the effect on meat quality attributes was minor.The nature of the relationship between humans and farm animals has multiple repercussions on the animals and the farmers and varies with farmers attitudes towards their animals. In particular, this relationship influences animal welfare and human working conditions. The present study, part of a larger research project investigating human-animal relationship (HAR) in pig farming and ways to improve it, had two objectives 1) to investigate the HAR in a diversity of pig farming situations and to evaluate the possible correlation between farmer attitudes, pigs' reactions to humans, husbandry practices, animal health, welfare and productivity and 2) to find a way to rapidly assign a farmer to a profile, in order to better adapt course content during training sessions on HAR. The study focused on 52 farrow-to-finish farms and consisted of a semi-structured interview with the farmer, observations of the farmer in contact with his/her livestock, two human approach tests conducted on sows and growers and productivity data.
