RESUMO
Animals have fundamentally contributed to the development and growth of different cinematographic and audiovisual activities. As established in article 13 of the Treaty on the Functioning of the European Union (TFEU), the basic text that establishes the objectives of the EU and from which the regulations or directives emanate, animal welfare is protected for the good of the general interest and therefore, must be taken into account when developing different European Union policies, especially those that may affect the internal market. This work aims to analyze each of the European regulations on animal protection and welfare to subsequently focus on each of the animal protection codes of the different countries of the union, trying to determine those premises related to the protection or the welfare of the animals that participate in these types of activities. We also wanted to make a brief comparison with countries such as the United Kingdom (UK) or the United States of America (USA), which are highly relevant to this topic. As a result of this analysis, the absence of standardized norms in the European Union has been revealed; however, in the UK and the USA, specific laws related to animal use in film media exist. Therefore, to develop new standards that guarantee the protection of animals in audiovisual productions in the EU are necessary, and these standards could also be expanded to other sectors or activities related to working animals.
RESUMO
The aim of this study was to assess the effects of replacing 44% of conventional feeds in a high-cereal concentrate (CON) with by-products (BYP concentrate; 18% corn distillers dried grains with solubles, 18% dried citrus pulp, and 8% exhausted olive cake) on the meat characteristics and fatty acid (FA) profile of fattening light lambs. Two groups of 12 Lacaune lambs were fed concentrate and barley straw ad libitum from 13.8 to 26.0 kg of body weight. There were no differences (p ≥ 0.130) between groups in the pH, chemical composition, color, and texture parameters and in the estimated proportions of pigments in the longissimus dorsi. Feeding the BYP concentrate reduced the concentration of thiobarbituric acid reactive substances (TBARS) in the meat after 6 days of refrigerated storage (unmodified atmosphere), probably due to the greater polyphenol content in this concentrate. Compared with CON-fed lambs, the meat and the subcutaneous fat from BYP-fed lambs had lower saturated and greater polyunsaturated FA content as well as greater n-6/n-3 FA. In summary, feeding a blend of corn distiller dried grains with solubles, dried citrus pulp, and exhausted olive cake did not change the composition of the meat but improved its antioxidant status and FA profile.
RESUMO
The objective of the study was to assess the effects of feeding sunflower meal (SM) and seeds (SS) protected against rumen degradation on carcass characteristics and composition and fatty acid (FA) profile of lamb meat. The protection of SM and SS was achieved by treating both feeds with malic acid at 150 °C for 2 h (MAH treatment) and in a previous study this treatment was shown to decrease ruminal degradability of protein of both feeds and fat degradability of SS. Two homogeneous groups of 12 lambs each were fed ad libitum high-cereal concentrates and cereal straw from 14 to 26 kg of body weight. The two concentrates differed only in the treatment SM and SS, which were included either untreated (control) or MAH treated. The MAH-fed lambs had greater thickness of dorsal fat (p = 0.016) and greater (p ≤ 0.016) values of the color parameters a* (redness) and C* (chromaticity) of the Rectus abdominis muscle. However, there were no differences in carcass measurements and in water-holding capacity, chemical composition, pH, color, or fatty acid of Longissimus muscle. In summary, the MAH treatment resulted in only subtle changes in meat composition and quality.
