RESUMO
Abstract This study assessed the anthelminthic feed additive albendazole effect on the main indicators of the quality of sheep meat obtained from infected and deworming animals. A total of 20 heads of Akzhaik meat and wool sheep (i.e. 2 years of age, of different sex) were used in a 20-day experiment and 2 groups of 10 heads were formed (n = 4). The sheep were fed with the basic diet (i.e. control, group CON), without adding anything, and the second group was fed the basic diet orally with the addition of a dose of 1.2 g / head (an experimental group). At the end of the experiment, a control slaughter was carried out from each group in order to study the biochemical composition of meat and its quality. The anthelmintic feed additive albendazole did not have a significant effect on the indicators (organoleptic and physicochemical) of meat quality (P> 0.04). However, the ratio of fat and ash in the meat of the control group has differences in indicators and is reduced by 24.81% and 0.03%, respectively. The drug had a significant effect on the biological value of meat in the experimental group, where there is a higher content of essential amino acids (P = 0.06), nonessential (P = 0.05) concentrations in comparison with the CON groups. The results obtained show that the meat of the experimental groups of sheep, when using the anthelminthic feed additive albendazole, did not have a significant effect on organoleptic parameters, but significantly positively influenced the metabolism, live weight gain and biological value of meat.
Resumo Este estudo avaliou o efeito do aditivo anti-helmíntico albendazol sobre os principais indicadores de qualidade da carne ovina obtida de animais infectados e desparasitados. Um total de 20 cabeças de carne Akzhaik e ovelhas de lã (ou seja, 2 anos de idade, de sexo diferente) foi usado em um experimento de 20 dias e dois grupos de 10 cabeças foram formados (n = 4). As ovelhas foram alimentadas com dieta básica (ou seja, controle, grupo CON), sem adicionar nada, e o segundo grupo foi alimentado com dieta básica por via oral com a adição de uma dose de 1,2 g / cabeça (um grupo experimental). Ao final do experimento, foi realizado um abate controle de cada grupo para estudar a composição bioquímica da carne e sua qualidade. O aditivo anti-helmíntico albendazol não teve efeito significativo sobre os indicadores (organolépticos e físico-químicos) de qualidade da carne (P > 0,04). No entanto, a proporção de gordura e cinzas na carne do grupo de controle tem diferenças nos indicadores e é reduzida em 24,81% e 0,03%, respectivamente. A droga teve efeito significativo sobre o valor biológico da carne no grupo experimental, onde há maior teor de aminoácidos essenciais (P = 0,06), concentrações não essenciais (P = 0,05) em comparação com os grupos CON. Os resultados obtidos mostram que a carne dos grupos experimentais de ovinos, ao utilizar o aditivo anti-helmíntico albendazol, não teve efeito significativo nos parâmetros organolépticos, mas influenciou positivamente de forma significativa no metabolismo, ganho de peso vivo e valor biológico da carne.

RESUMO
Food security is important, and is being increasingly focused on during animal production. In bovine carcasses, we can find hematomas that are the consequences of traumas caused by several factors. These cause the extravasation of blood from vessels, causing the blood to accumulate in muscular tissues, which can then serve as a substrate for bacterial proliferation. The objective of this study was to quantify the occurrence of hematomas in bovine carcasses and to determine their degree of severity, to measure the economic impact these hematomas can cause. The slaughter of 385 animals was monitored, and 56.88% showed some type of hematoma. In injured animals, there were a total of 427 lesions, with an average of 1.94 of injuries per animal. There was a total loss of 65.7 kg of meat, with following proportional distribution: 12.32% in the front room (8.1 kg), 33.18% near the ribs and the lumbar region (21.8 kg), and 54.49% (35.8 kg) in the hindquarter. The resulting economic loss was calculated to be a total of US$ 206.66 (R$ 817.93). We conclude that the occurrence of hematoma lesions in bovine carcasses from the north central mesoregion of Paraná is responsible for economic losses.(AU)

Objetivou-se quantificar a ocorrência de hematomas em carcaças bovinas e determinar o grau de severidade destes, a fim de mensurar o impacto econômico causado. Realizou-se o acompanhamento do abate de 385 animais e constatou-se que 56,88% apresentavam algum tipo de hematoma. Dentre os animais lesionados houve um total de 427 lesões, sendo em média 1,94 de lesões por animal. Perfazendo uma perda de 65,7 kg de carne no total, distribuídos em 12,32% no quarto dianteiro (8,1kg), 33,18% na região das costelas e lombar (21,8kg), e maior perda no quarto traseiro, sendo 54,49% (35,8 kg). O resultado econômico das perdas evidenciam um total de U$ 206,66 (R$ 817,93). Foi possível concluir que a ocorrência de lesões decorrentes de hematomas em carcaças bovinas provenientes da mesorregião norte central do Paraná é responsável por perdas econômicas.(AU)

The aim of this study was to determine the effect of lycopene addition to the curing mixture for steamed and grilled breast muscles on the chemical composition, sensory attributes and physicochemical parameters of the final products. The experimental material comprised a total of 48 breast muscles of Hybrid XL turkeys aged 15 weeks and fed commercial pelleted diets. The material was divided into three groups (control, experimental groups I and II). Sixteen breast muscles (8 left and 8 right) were assigned to each group. Control group samples were immediately transported to a laboratory. The remaining 32 muscles were steamed and grilled, where 16 samples were cured before heat treatment. The curing brine contained tomato peel extract standardized for 5% lycopene content. The results of the study indicate that the lycopene increased vitamin E levels and decreased the ash and vitamin A content of the final products. Lycopene also lowered the aroma and flavour scores, and increased the shear force values of the final products. The addition of lycopene lowered the pH of the products measured in a water homogenate and deteriorated the hydration properties of meat. Lycopene increased the darkness and the contribution of redness, which led to an increase in colour saturation and hue values of the evaluated samples. It can be concluded that lycopene exerted antioxidant effects and improved the colour parameters on the external surface and along the cross-section of processed meat. However, the specific flavour of tomatoes deteriorated the sensory attributes of the final products.

The present research was aimed at analyzing the performance and the chemical composition of the chicken meat (chest and thigh/on-thigh) fed with different rations containing fish meal or white oat. Five treatments with 5 repetitions with 10 birds for each experimental unit had been tested, totalizing 250 animals created, from 1 to 40 days old. The chickens had been lodged in cages receiving rations contend 4.5% and 9% of fish meal, or, 10% and 20% of white oat, and the control diet. The chemical analyses of humidity, ashes, rude protein and ether extract were done in an animal for each repetition. It was not observed difference (P>0.05) for the ration consumption, gain of daily weight and alimentary conversion. There was no difference (P>0.05) in the chemical composition of the chest broiler meat. In the thigh/on-thigh analyzed, the treatment including 9% of fish meal provided significant increase of lipids in relation to the control diet and to that including 20% of white oat ration. It is conclude, that it is possible to use the 4 types of rations tested without intervening in the birds performance, being that, the 9% of fish flour inclusion and 10% of oat had increased the lipids in the chickens thigh/on-thigh meat.(AU)
O presente trabalho objetivou analisar o desempenho zootécnico e a composição química da carne dos frangos (peito e coxa/sobrecoxa) alimentados com diferentes rações, contendo farinha de peixe ou aveia branca. Foram testados 5 tratamentos, com 5 repetições, com 10 aves por unidade experimental, totalizando 250 animais criados, de 1 a 40 dias de idade. Os frangos foram alojados em gaiolas, recebendo rações contendo 4,5 e 9% de farinha de peixe, ou 10 e 20% de aveia branca, e ração controle. As análises químicas de umidade, cinzas, proteína bruta e extrato etéreo foram feitas em um animal de cada repetição. Não foram observadas diferenças (P>0,05) para o consumo de ração, o ganho de peso diário e a conversão alimentar. Não houve diferença (P>0,05) na composição química da carne do peito de frango. No corte coxa/sobrecoxa analisado, o tratamento com inclusão de 9% de farinha de peixe proporcionou aumento significativo de lipídios em relação à ração controle e àquela com inclusão de 20% de aveia branca. Conclui-se, portanto, que é possível utilizar os 4 tipos de rações teste sem interferir no desempenho das aves, sendo que a inclusão de 9% de farinha de peixe e de 10% de aveia aumentaram os lipídios na carne da coxa/sobrecoxa dos frangos.(AU)
