국내의 동물복지 개념의 도입은 해외 선진국에 비해 늦었으나 정부 주도에 의해 비교적 적극적인 동물복지정책들이 도입되고 있다. 그러나 축산업 현장에서 동물복지 인식이 충분치 못하기 때문에 자발적인 개선이 아닌 정부의 정책수단에 의하여 동물복지를 추진하고 있는 실정이다. 본 연구에서는 국내 산란계 농가를 중심으로 최근 5년간 도입된 동물복지 관련 정책이 현장에서 유발하는 갈등을 유형화하여 파악하기 위하여 산란 농장 운영자들의 동물복지 관련 의식수준 및 동물복지 관련 규정 준수여부를 조사하였다. 산란 농가 현장방문을 통하여 설문조사를 진행하였으며, 산란양계농장 운영자(소유자 혹은 관리 책임자)를 대상으로 53가구의 산란양계 농가를 조사하였다(2020년 산란양계농가 수 797가구 수 기준 90% 신뢰수준(Z-score: 1.65) 10.18% 허용 오차). 현장에서의 갈등을 윤리적 고려 수준에 따라 소극적, 중도적, 적극적 3가지로 유형화하였다. 또한 윤리적 고려 수준에 따라 동물복지 관련 규정 준수 여부와의 상관관계를 조사하였다. 결과적으로, 축산 현장에서의 동물복지 관련 규정 준수 여부는 축산 농장 운영자의 윤리적 고려수준의 영향을 받는 것을 확인할 수 있었다. 다만 예외적으로 농장 운영자의 동물복지 의식수준이 높음에도 동물복지 관련 규정은 준수하지 못하는 갈등상황이 확인되었는데, 이는 현장에서 인지하고 있는 규정과 정책의 충돌로 인해 발생한 갈등 상황임을 확인할 수 있었다. 이처럼 정책 수단에 의해 추진되는 동물복지가 효과적일 수는 있지만, 아직은 현장에서 갈등을 유발하고 있음을 확인할 수 있었다.

Intensive farming methods that do not guarantee animal welfare can induce stress in pigs. Stress, in turn, can reduce their disease resistance and influence their hormones and metabolites in such a manner that productivity is negatively affected. This study was conducted to compare the stress related factors and blood characteristics of pigs raised on conventional farms and those raised on animal welfare farms. We measured the levels of cortisol, epinephrine and norepinephrine, biochemical parameters in blood and glycogen, L-lactate and heat shock protein 70 (HSP70) in muscle, as physiological markers of indicating the stress in conventional farm pigs (Control, n=10) and animal welfare farm pigs (Welfare, n=10). We found that there was a significant difference in the albumin-globulin ratio (A/G ratio), as well as the albumin (ALB), blood urea nitrogen (BUN) and aspartate aminotransferase (AST) levels between the two farms. Epinephrine was significantly higher in conventional farm, while level of norepinephrine was higher in animal welfare farm. There was no significant difference in cortisol, which is known as a stress hormone, across the two groups of farms. Muscular glycogen content was significantly high in animal welfare farm pigs. While L-lactate tended to be low in the animal welfare farm pigs, the difference between them and the conventional farm cohorts was not significant. HSP70 showed high levels of expression in conventional farm. Thus, we suggested that blood parameter results showed a stress response in the livers of conventional farm, and that catecholamine hormones, glycogen, L-lactate and HSP70 can be used as physiological factors of assessing animal welfare.

Meat quality includes technological quality attributes, consumer acceptance, and credence characteristics. In terms of credence characteristics, animal welfare is one of the most interesting topics to both consumers and the livestock industry. Consumers prefer meat produced from livestock that has been raised in low stress and ecofriendly environments. The livestock industry cares about animal welfare to meet the requirements of consumers. Animal welfare is closely associated with the stress and physiological response of livestock to stress. Moreover, stress just before slaughter (i.e., pre-slaughter stress) has negative effects on not only animal welfare but also ultimately on meat quality. It is well-documented that pre-slaughter stress can influence ante- and post-mortem biological changes of the muscles, especially their metabolic properties and metabolites. The metabolic properties and metabolites contents also can modulate the postmortem changes of the muscles. Conversion of muscles to meat during postmortem is a very important process because it determines ultimately the meat quality. Thus, understanding pre-slaughter stress and physiological responses to stress in farm animals is important for animal welfare and meat quality. The purpose of this paper was to examine the concept of stress, physiological responses to stress, measurement of stress, and the relationships between stress indices and meat quality traits.

This study was performed to development the alternative farrowing pen (AFP) and to investigate performance and behavior of lactating sows and their litter. A total of 64 multiparous sows were randomly divided into two groups and were allocated to farrowing crates (FCs) and AFPs. The AFPs contained a crate and support bars that could be folded to provide the sows with extra space on day 5 postpartum. Behavior was recorded by charge-coupled device cameras and digital video recorders, and the data were scanned every 2 min to obtain an instantaneous behavioral sample. Farrowing systems did not affect feed intake, back-fat thickness, litter size and piglet weight at birth and weaning (p > 0.05). In addition, there were no differences in the number of crushed piglets between the two farrowing systems (p > 0.05). However, the weaning-to-estrus interval was shorter in the sows of the AFPs than in thous of the FCs (p < 0.05). The sows spent most of their time lying down during the lactating period, at about 80% lateral recumbency and 10%-15% ventral recumbency. The only significant differences were in the feeding and drinking behavior between sows in the two farrowing systems (p < 0.05). The FC sows displayed more feeding and drinking behavior than the AFP sows, especially in the late lactating period (p < 0.05). Piglets in the FCs tended to spend more time walking than piglets in the AFPs (p < 0.05), whereas there were no differences in suckling and lying behavior between piglets in the two farrowing systems (p > 0.05). It is concluded that the AFPs with temporary crating until day 4 postpartum did not negatively affect performance and crushed piglet compared with the FCs. It also may improve animal welfare by allowing sows to move and turn around during the lactating period. Further research is needed to find suitable housing designs to enhance productivity and animal welfare.

본 연구는 동물복지 인증기준의 개선을 위해 농가 현장조사를 실시하였으며, 더불어 국내 농가환경에 적합한 동물복지 수준평가 방법을 개발하고자 일부 인증 농가를 대상으로 동물복지 수준의 기초자료를 확보하고자 조사를 실시하였다. 연구조사의 대상은 동물복지 산란계 인증농가 10개소를 선정하였으며, 산란계 인증농가 사육시설 조사는 사육형태, 사육두수, 사료와 음수 공간, 사육밀도, 횃대의 길이 및 모양을 수집하였다. 동물복지 수준 평가는 모래목욕의 유무, 산란상 사용, 환경풍부화물 제공, 방사장 제공, 깃털손상, 쪼기에 의한 상처 유무를 조사였다. 연구결과는 동물복지 산란계 인증농가들의 대부분이 인증기준을 준수하고 있었다. 일부 농가에서 과도한 인증기준을 지적하였는데 실제 농가내부에 급이기, 급수기 및 횃대의 시설로 인해 닭들이 움직일 수 있는 공간이 제한적인 것으로 판단되었다. 모든 농가들에서 산란상을 제공하고 있었으나 방란율이 20%이상인 농가도 있어 산란상 활용에 문제가 있음을 확인하였다. 횃대의 경우 길이는 충족하고 있었으나 10개 농가 중 3개 농가에서만 둥근형태의 횃대를 사용하고 있었다. 모든 농가에서 깔짚을 제공하고 있었으나 보충 또는 교체가 이루어지지 않아 바닥이 단단해져 닭들이 모래목욕행동을 보이지 않는 농가도 2개소나 되었다. 환경풍부화물의 경우 사료 외에 풀사료 등을 제공하는 농가는 4개소로 조사되었다. 대부분의 조사농가에서 깃털손상이 확인되었는데 이것은 조사농가 모두 유정란을 생산하고 있어 수탉에 의한 깃털손상일 것으로 판단된다. 본 연구에서 10개소의 농가만 조사하였기 때문에 전체 인증농가를 대표할 수는 없으나 일부항목에서 조사농가들 사이에서도 큰 차이를 보이고 있어 동물복지 수준평가에 면밀한 분석이 이루어져야 할 것으로 판단된다.

To predict the apparent total tract digestibility (ATTD) of crude protein (CP) in dogs we developed an in vitro system using an in vitro digestion method and a statistical analysis. The experimental diets used chicken meat powder as the protein source, with CP levels of 20% (22.01%, analyzed CP value as dry-based), 30% (31.35%, analyzed CP value as dry-based), and 40% (41.34%, analyzed CP value as dry-based). To simulate in vivo digestive processes a static in vitro digestion was performed in two steps; stomach and small intestine. To analyze ATTD the total fecal samples were collected in eight neutered beagle dogs during the experimental period. CP digestibility was calculated by measuring CP levels in dog food, in vitro undigested fraction, and dog feces. In result, CP digestibility at both in vivo and in vitro was increased with increasing dietary CP levels. To estimate in vivo digestibility the co-relation of in vivo ATTD and in vitro digestibility was investigated statistically and a regression equation was developed to predict the CP ATTD (% = 2.5405 × in vitro CP digestibility (%) + + 151.8). The regression equation was evaluated its feasibility by using a commercial diet. The predicted CP digestibility which was calculated by the regression equation showed high index of similarity (100.16%) with that of in vivo in dogs. With that, it would be a feasible non-animal method to predict in vivo CP digestibility by using in vitro digestion method and the proposed linear regression equation in adult dogs.

This review was performed to investigate the current researches on the welfare of rearing environments system in farming chicken, including stocking density, perch, housing system and research trend. The investigation indicated that most of the developed countries took much efforts into making appropriate regulations to improve the welfare of rearing environment about broilers and laying hens, particularly more parts in laying hens. Recently the regulations have varied a lot, to be more detailed than before. Moreover, some regulations give valuable suggestions to improve well-being of poultry industry such as additional facilities. Until now it has been known, the quality of the products will improve and the income of producers will increase along with the improvement of welfare. Therefore the relevant agencies and organizations can strengthen the belief of consumers especially the competition is so fierce today. In conclusion, improvement of poultry welfare should be carried out in the real situation and international trends to create the appropriate rules such as professional consulting and training.

A significant proportion of the African continent is conducive for animal agricultural production, due to its historical experience and available resources to accommodate and nurture various indigenous and exotic animal species and breeds. With food security being a global challenge, animal products can play an important role as nutrient dense food sources in human diets, particularly in Africa. However, this does not seem to reach its full potential in practice, due to numerous reasons that have not been adequately addressed. Animal welfare reservations can be highlighted as one of the major contributing factors to the curbed progress. The consequences have been scientifically proven to affect product quality and market access. However, in the African community, the concept of animal welfare has not been fully embraced. While there are international animal welfare standards in the developed world, there are inherent factors that hinder adoption of such initiatives in most developing regions, particularly among communal farmers. These include cultural norms and practices, social ranking, socio-economic status, available resources, information dissemination and monitoring tools. Therefore, there is need to harmonize what is internationally required and what is feasible to accommodate global variability. The protocols followed to ensure and evaluate farm animal welfare require regular investigation, innovation and a sustainable approach to enhance animal productivity, efficiency and product quality. Additionally, investing in animal wellbeing and health, as well as empowering communities with significant knowledge, has a potential to improve African livelihoods and contribute to food security. This review seeks to highlight the concept of animal welfare in relation to livestock and food production in African conditions.

Objective: This study aimed to evaluate the difference in the thigh meat quality of Ross 308 broiler from conventional and welfare farms. Methods: Thigh meat samples of Ross 308 broilers (age, 35 d; carcass weight, 1.1 kg) from conventional farm (RCF, n = 60) and animal welfare farms (RAWF, n = 60) were analyzed. Proximate composition, pH, color (lightness, redness, and yellowness), water-holding capacity (WHC), shear force, total aerobic bacteria (TAB), and volatile basic nitrogen (VBN) were measured and the levels of bioactive compounds such as dipeptides (anserine and carnosine), creatine, creatinine, and their anti-oxidation activity were determined. Results: The RCF and RAWF did not differ significantly in their proximate composition, WHC, color, and creatine and carnosine levels. The pH value was significantly lower in RAWF than in RCF on day 7. The shear force value was significantly higher in RAWF than in RCF throughout the storage duration. TAB in RCF on day 9 were significantly higher than those in RAWF. The VBN content of RAWF was significantly lower than that of RCF after 5 days of storage. Creatinine content was significantly higher in RAWF (3.50 mg/100 g) than in RCF (3.08 mg/100 g) on day 1. Along with higher carnosine and anserine contents of RAWF, it had significantly higher 2,2-diphenyl-1-picrylhydrazyl and 2,2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activities than those of RCF. Conclusion: These results imply that the animal welfare farming system beneficially affects the overall oxidative stability of Ross 308 thigh meat.
