The Effect of Space Allowance During Pre-Slaughter Transport of European Quail Breeders on Welfare, Carcass Traits and Meat Quality

The objective was to evaluate whether space allowance during pre-slaughter transport of European breeding quail affects welfare, carcass traits and meat quality. A total of 248 quails (body weight = 344.90 ± 2.09 g) were used. During pre-transport, the quails were fasted for 5 hours and 30 minutes. The poultry were caught and placed in plastic transport crates with an area of 0.40 m2. The treatments consisted of a different space allowance in each crate: 22, 28, 34 or 40 quails per crate. Immediately upon arrival at the slaughterhouse, the quails were stunned. During bleeding, blood samples were collected. The carcasses were individually weighed. The meat quality was measured. Data were analysed using the effects of space allowance during transport of quails and pickup truck as dependent variables. Death on arrival increased as the space allowance in transport crates decreased (p=0.08). Glucose and uric acid levels were not significantly different between groups (p≥0.14). The cold carcass weight presented the maximum value when the crates contained 31 quails (p=0.03). The meat pH, intensity of red, intensity of yellow and cooking losses were not different between groups (p≥0.12). The meat lightness value presented the maximum value when the crates contained 31 quails (p=0.04). In view of the above, the number of European breeding quails transported in crates must not exceed 30 animals.(AU)

Perfil do consumidor de ovos e carne de frango do município de Janaúba-MG / The consumer profile of eggs and chicken meat from the municipality of Janaúba-MG

Neste estudo foi caracterizado o perfil do consumidor do município de Janaúba-MG, em relação ao consumo de ovos de poedeiras comerciais e carne de frango. Foram aplicados 155 questionários, utilizando-se o método “survey”, estruturados com perguntas discursivas e de múltipla escolha e direcionados a pessoas escolhidas aleatoriamente. Constatou-se que a preferência por ovos brancos foi mais elevada (46,45%) comparada aos vermelhos (34,19%), em virtude da aparência (40,65%). Alguns consumidores acreditam que o ovo, dependendo da cor da sua casca, não apresenta equivalência nutricional (23,23%) e a maioria (45,81%) afirmam que a qualidade externa é o fator que mais influencia no ato da compra. No entanto, o consumo semanal pela maior parte dos entrevistados é baixo, não ultrapassando duas vezes por semana (47,74%). Com relação à carne de frango, a maioria consome (72,99%), e o frango caipira é o preferido pelos consumidores (50,32%). Entretanto, o consumo da carne ocorre, no máximo, duas vezes por semana (56,57%). 27,1% dos entrevistados afirmaram não consumir carne de frango; destes 3,87% acreditam que a mesma possui antibióticos e 8,39%, hormônios. Do total de entrevistados, 78,06% já ouviram falar em bem-estar animal. Destes, 83,23% aceitariam pagar mais caro por um produto obtido de aves criadas em sistemas que seguemos padrões de bem-estar. 73,13% dos entrevistados aceitariam pagar mais por um ovo enriquecido nutricionalmente. Mediante o exposto, observa-se que o baixo consumo tanto da carne quanto do ovo está associado a falsas informações divulgadas relativas à alimentação das aves e ao sistema de produção. Portanto, se fazem necessários maiores esclarecimentos sobre as questões levantadas, o que pode refletir em aumento no consumo tanto dos ovos quanto da carne de frango.(AU)

This study characterized the municipality of Janaúba-MG user profile, in relation to the consumption of eggs commercial laying hens and chicken meat. 155 questionnaires were applied, using the method "survey", structured with essay questions and multiple choices and targeted to people chosen at random. It was found that the preference for white eggs was higher (46.45%) compared to red (34.19%), because appearance (40.65%). Some consumers believe that the egg depending on the color of its bark, has no nutritional equivalence (23.23%) and the majority (45.81%) state that the external quality is the factor that most influences upon purchase. However, the weekly consumption by most respondents is low, not more than twice a week (47.74%). With regard to chicken meat, most consuming (72.99%), and the jerk chicken is preferred by consumers (50.32%). However, the consumption of meat is no more than twice a week (56.57%) 27.1% of respondents said they consume chicken meat; 3.87% of these believe that it has antibiotics and 8.39%, hormones. To total respondents, 78.06% have heard of animal. Destes welfare, 83.23% would accept paying more for a product obtained from birds reared in systems seguemos welfare standards. 73.13% of respondents would accept paying more for an enriched egg nutritionally. Through the above, it is noted that the low power consumption as much meat as egg is associated with false information disclosed for the feeding of poultry and the production system. So are needed further clarifications on the issues raised, which may reflect increased consumption of both eggs as the chicken.(AU)

Effect of creatine addition in feeds containing animal meals on the performance and carcass yield of broilers

The objective of this study was to evaluate the performance and carcass characteristics of broilers fed exclusively vegetable diets and diets containing animal meal with the addition of creatine or not after day 8. In the experiment, 1080 one-day-old male chicks were distributed according to a completely randomized experimental design into six treatments with six replicates each. A control diet based on corn and soybean meal was formulated, to which animal meals and creatine were included or not. Diets were formulated to contain equal mineral (calcium, phosphorus and sodium) and amino acid (available methionine + cystine, lysine and threonine) levels. The following treatments were applied: A. control (diet based on corn and soybean meal); B. control + creatine (600g/ton); C. inclusion of 5% meat and bone meal (MBM), D. inclusion of 5% MBM + creatine (600g/ton), E. inclusion of 5% blood meal (BM), F. inclusion 5% BM + creatine (600g/ton). Weight gain, feed intake, feed conversion, carcass yield and viability were evaluated. At 42 days of age, BM dietary inclusion impaired weight gain and feed conversion ratio. The inclusion of MBM affected only feed conversion ratio. The addition of creatine ito the diet with BM improved weight gain when compared with the BM diet with no creatine. The addition of creatine to the diet containing 5% BM improved weight gain when compared with the same diet without the use of the additive.(AU)
