“…Additionally, birds subjected to group stress can experience secondary welfare consequences as result of negative interactions within the group; these are in particular ‘Soft tissue lesions and integument damage’ from injurious pecking. For example, aggressive pecking is one of the most common causes of skin or eyelid lesions, head injuries and eye loss in quail (Kiani, 2022 ), and pecking also causes serious injury in ducks (Rodenburg et al., 2005 ). These ABMs are therefore discussed in the appropriate sections (e.g.…”

This Scientific Opinion concerns the welfare of Domestic ducks (Anas platyrhynchos domesticus), Muscovy ducks (Cairina moschata domesticus) and their hybrids (Mule ducks), Domestic geese (Anser anser f. domesticus) and Japanese quail (Coturnix japonica) in relation to the rearing of breeders, birds for meat, Muscovy and Mule ducks and Domestic geese for foie gras and layer Japanese quail for egg production. The most common husbandry systems (HSs) in the European Union are described for each animal species and category. The following welfare consequences are described and assessed for each species: restriction of movement, injuries (bone lesions including fractures and dislocations, soft tissue lesions and integument damage and locomotory disorders including lameness), group stress, inability to perform comfort behaviour, inability to perform exploratory or foraging behaviour and inability to express maternal behaviour (related to prelaying and nesting behaviours). Animal-based measures relevant for the assessment of these welfare consequences were identified and described. The relevant hazards leading to the welfare consequences in the different HSs were identified. Specific factors such as space allowance (including minimum enclosure area and height) per bird, group size, floor quality, characteristics of nesting facilities and enrichment provided (including access to water to fulfil biological needs) were assessed in relation to the welfare consequences and, recommendations on how to prevent the welfare consequences were provided in a quantitative or qualitative way.

“…Водночас, зустрічаються повідомлення про те, що ефективнішим є утримання курей в угрупуваннях невеликих розмірів. Таким чином, описані в літературі дослідження щодо оптимального розміру групи досить неоднозначні, а також проведені в експериментальних умовах, що ускладнює екстраполяцію результатів на промислові умови, де одночасно вирощують сотні тисяч курей (Kiani, 2022). Отже, величина угрупування несучок яєчного кросу за їх утримання в клітках 12-ярусних батарей є чинником, що впливає на їх збереженість, несучість, ефективність використання наявних площ, обсяги та ефективність виробництва харчових яєць.…”

The group size of hens is one of the key stimuli that affects the welfare of the bird. This is especially important for hens, which evolutionarily live in much smaller groups in the natural environment than in the conditions of enterprises producing edible eggs. But the specific parameters of hеns group size for keeping them in cages of multi-tiered batteries of traditional structures, known as "conventional cages" or "battery cages" according to the international classification, are not regulated by either domestic or foreign standards. There are only restrictions on the minimum number of chickens in one cage of batteries of "improved" designs ("modified enriched cages", or "furnished cages"). It should be at least 7 birds. Therefore, the purpose of the work was to study the productivity and efficiency of the production of edible eggs by increasing group size of hеns in cages of 12-tier batteries of traditional structures from 9 to 93 birds at the standard stocking density (area provision). For this, in the conditions of a modern complex for the production of edible eggs, 4 groups of hens were formed, each of which was kept in a separate poultry house-similar in area (2915 m2), equipped with 12-tier "Big Dutchman" cage batteries, the size and area of which cages differed. The group size of hens on 1st group was 9 birds/cage, 2 groups – 17 birds/cage, 3 groups – 52 birds/cage, 4 groups – 93 birds/cage, density of keeping hens of all groups – 22.6-23.1 birds/m2 with regulatory requirements no more than 25 birds/m2. It was established that an increase the group size of hens in cages from 9 to 93 birds contributes to an increase in the level of preservation (by 5.7%), laying per initial laying hen (by 9.1%), the volume of egg production (by 71.4%), in including based on the calculation per 1 m2 of the poultry house area, the level of profitability of their production from 34.7% to 40.1% and the reduction of the cost price from 1.70 to 1.56 UAH/egg.

IntroductionIt is estimated that 1.4 billion quails are reared each year for their eggs and meat, but animal welfare assessment protocols for this species have yet to be established. The objective of this study was to devise an animal welfare assessment protocol developed through a multidimensional approach that contained a number of animal-based indicators (ABIs) for quails (Coturnix japonica) reared for meat production.MethodsDuring 2021 and 2022, the identical auditor visited and audited 14 Spanish farms in their initial year of integration into an animal welfare certification scheme. The protocol is categorised into 4 principles and 12 criteria. The “good feeding” principle includes 6 indicators (1 ABI), “good housing” includes 10 indicators (5 ABIs), “good health” includes 12 indicators (9 ABIs), and “appropriate behaviour” contains 8 indicators (5 ABIs). The final welfare assessment is calculated at the farm level using scores from the on-farm recordings. The assessment is a step-by-step weighted sum of the scores from the various indicators, with the final score ranging between 0 and 100.Results and discussionThe main welfare issues found on all farms were a lack of temperature and humidity records, a poor lighting pattern, and the absence of an outdoor range or access to one. To a lesser degree, it was also found that there were excessive numbers of birds per feeder, the presence of improperly functioning drinkers (i.e., not working, inadequate water flow, or dripping water), poor litter quality, and a high prevalence of birds with dirty plumage and lameness. Despite this, the farms achieved a good overall score, being classified as “enhanced” (n = 11) and “acceptable” (n = 3). The tool proved helpful in identifying specific welfare issues at the farm level and conducting benchmarking.
