Zhang D, Yuan C, Guo T, Liu J, Lu Z. Effects of Different Dietary Energy Levels on Development, Quality of Carcass and Meat, and Fatty Acid Profile in Male Lambs. Animals (Basel) 2023; 13:2870. [PMID: 37760270 PMCID: PMC10525359 DOI: 10.3390/ani13182870] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 07/25/2023] [Accepted: 08/25/2023] [Indexed: 09/29/2023] Open
Abstract
This experiment was conducted to study the effects of dietary energy level on the growth performance and meat quality of weaned Alpine Merino lambs. The study ran for a total of 104 days (20-day pretrial, 84-day trial). From three groups of test lambs, we randomly selected ten lambs per group to determine slaughter performance, meat quality characteristics, and organ indexes. The slaughter performances of the lambs improved as the dietary energy level increased. The live weight before the slaughter of the lambs was significantly higher in the high group than in the low and medium groups. The carcass weight was significantly higher in the high group than in the low group. Dietary energy level had little effect on the organ weight of lambs. Meat quality differed among the three dietary energy levels. The muscle yellowness and redness scores decreased significantly as the energy levels increased. The C18:0, C21:0, C20:1, C18:2n6c, and C20:2 contents in the muscle were significantly higher in the high group than in the medium and low groups. The C18:3n6 content in the muscle was significantly higher in the low group than in the medium group. The C20:5n3 content in the longissimus dorsi was significantly higher in the high group than in the medium and low groups. The monounsaturated and unsaturated fatty acid contents in the muscle were significantly higher in the high group than in the low group. A dietary energy level of 10.5 MJ/kg is suitable for fattening weaned male Alpine Merino lambs.

Cottonseed and Soy-bean agro-industrial by-products used in feedlot cattle diet: effects on beef fatty acid profile and quality parameters. REVISTA BRASILEIRA DE SAÚDE E PRODUÇÃO ANIMAL 2022.

Abstract
ABSTRACT Beef composition are directly influenced by the dietary fat, particularly in ruminants, due to rumen biohydrogenation, which promotes alterations in the dietary fatty acid (FA) profile and affects the meat quality. Beef sensorial, chemical, and FA compositions of intramuscular and subcutaneous fat were evaluated, from 40 Nellore males finished on feedlot diet based, containing cottonseed (CSB) and soybean by-product (SOB) as agro-industrial by-product fat sources. CSB as a fat source, did not alter the beef pH, shear force, chemical composition, or subcutaneous FA profile compared with the SOB diet. Differences were observed at yellow and red beef color, with low and high CSB diet inclusion; on the contrary, inclusion of SOB in the diet led to an intensely unpleasant aroma in aged and cooked meats. Regarding beef FA profile, CSB with 3% dietary fat produced steaks with a lower proportion of C 17:0 , having 1.359 and 3.238 g/100 g of intramuscular FA, whereas CSB with 5% dietary fat led to an increase in C 18:2 n -6 , with 0.298 and 0.132 g/100 g of intramuscular FA in steaks from animals fed with CSB and SOB, respectively. CSB produced more intense red beef color, unpleasant aroma, and higher linoleic acid content; however, the color and aroma of the meat produced from cattle fed with CSB in the diet were less intense and were like those observed in cattle fed with SOB; these could therefore be recommended for use as agro-industrial by-products in beef cattle diet.

Abstract
The effects of different fats in the diet were evaluated on the basis of animal performance, carcass and meat-quality traits. Four groups of eight Friesian steers were intensively finished with concentrate and cereal straw given ad libitum. Four different types of fats were included at a 4% level in the diet, namely, palm oil, sunflower oil, tallow and hydrogenated fat. The feeding trial lasted for 84 days. There were no differences on animal performance or carcass characteristics, except for animals from the hydrogenated-fat diet, which had the greatest percentage of muscle and moisture, and the lowest percentage of fat in a 6th rib dissection. Meat colour, texture, lipid oxidation and consumer acceptability did not differ among the diets. Nevertheless, the effects of ageing or display time were more important than those of the source of fat. Intramuscular fatty acid profile was hardly influenced by the fat source. In conclusion, the type of fat added at the final stage of the rearing process, at a 4% of inclusion level, did not produce noticeable variations on productive parameters or product quality. This would allow to formulate rations for cattle, using the most profitable source of fat (added at low levels), without having variability on the product quality.

Abstract
Objetivou-se avaliar a eficiência de dietas contendo diferentes aditivos sobre o desempenho, características qualitativas da carcaça e da carne de 150 novilhas Brangus suplementadas a pasto diariamente com 0,32% do peso vivo. Os tratamentos foram: suplemento base (sem aditivos); farinha de algas calcárias (Lithothamnium calcareum) adicionada ao suplemento base; vitamina E e selênio orgânico adicionados ao suplemento base; gordura protegida adicionada ao suplemento base; uma aplicação por via subcutânea de vitamina D 7 dias antes do abate + suplemento base; e uma associação de vitamina E, selênio orgânico e gordura protegida adicionados ao suplemento base + uma aplicação por via subcutânea de vitamina D 7 dias antes do abate. Os animais foram suplementados por 109,80 ± 11,71 dias, quando foram abatidos ao alcançarem 337,95 ± 20,56kg de PV. O delineamento experimental foi inteiramente casualizado, com seis tratamentos e 25 repetições. O desempenho, as características de carcaça e da carne não foram afetados pelos aditivos utilizados. A média da área de olho de lombo de 52,00 cm² e a média da espessura de gordura subcutânea de 3,58mm dos animais que receberam a associação de aditivos não diferiram dos valores dos animais do tratamento controle. A adição de vitamina D3 não teve efeito sobre a força de cisalhamento da carne. O uso de aditivos conforme os protocolos adotados não foi eficiente para melhorar o desempenho, as características de carcaça e as características físicas da carne de novilhas suplementadas a pasto.

Abstract
Objetivou-se com este trabalho avaliar as características de carcaça e cortes comerciais de tourinhos Red Norte suplementados com óleos de fritura e de soja terminados em confinamento. Utilizaram-se 27 animais Red Norte com peso corporal inicial médio de 317 ± 33kg. Os animais receberam ração ad libitum com relação volumoso:concentrado 40:60, sendo: dieta controle; suplementados com óleo de soja e suplementados com óleo de fritura, durante 112 dias, sendo 28 dias de adaptação, e abatidos com 481,0; 488,7 e 462,6kg para os tratamentos controle, suplementados com óleo de soja e óleo de fritura respectivamente. A espessura de gordura subcutânea (EGS) e a área de olho de lombo (AOL) foram medidas entre a 12ª e 13ª costelas. A suplementação com fontes lipídicas não influenciaram o peso final, peso de carcaça quente, peso de carcaça fria, AOL, EGS, perdas por resfriamento, pesos e rendimentos dos cortes dianteiro, traseiro especial e ponta de agulha. Entretanto o rendimento de carcaça foi menor para animais suplementados com óleo de soja. O pH final foi maior (P<0,01) para as carcaças dos animais suplementados com óleo de fritura, e a temperatura final (P<0,02), foi maior para os animais com suplementação lipídica em relação aos animais sem suplementação. A suplementação lipídica utilizada para tourinhos em confinamento não influenciou as características de carcaça. Entretanto, animais suplementados com óleo de fritura apresentaram carne DFD, enquanto os animais suplementados com óleo de soja apresentaram menor rendimento de carcaça.
