Efeito da adição de aminoácidos protegidos (metionina e lisina) no desempenho e nas características da carcaça de cordeiros árabes machosRESUMO Este estudo foi realizado na Agricultural Research Station of the College of Agriculture / Basra University / Karma Ali, no período de julho de 2019 a maio de 2020, para avaliar o efeito da adição de aminoácidos protegidos (metionina e lisina e a mistura destes) no desempenho de cordeiros Arabi e algumas características das carcaças. 16 cordeiros machos foram selecionados com um peso médio de 27,95 kg, com 5 a 6 meses de idade e foram distribuídos aleatoriamente em quatro tratamentos, sendo quatro animais por tratamento, e foram alojados em gaiolas separadas para cada grupo; primeiro o tratamento controle (sem aditivos); o segundo tratamento (5 g) de metionina protegida; o terceiro tratamento (5g) de lisina protegida; o quarto tratamento (5g + 5g) de metionina e lisina protegida por kg de mistura alimentar, por (90) dias. Os resultados indicaram um aumento significativo (p< 0,05) a favor do quarto e do segundo tratamento nas taxas finais de peso vivo e no ganho diário e total de peso em comparação com o primeiro tratamento e houve uma melhora na quantidade de alimento consumido e a eficiência da conversão alimentar. Além disso, houve um aumento significativo (p< 0,05) nos pesos de carcaça, taxas de depuração e pesos das articulações dos ombros e pernas do quarto e do segundo tratamentos em comparação com o primeiro tratamento. Não houve diferenças nos pesos dos cortes no pescoço, lombo e costelas.PALAVRAS-CHAVE: aditivos alimentares; desempenho de carcaça de cordeiro; aminoácido protegido.

“…This result was in agreement with the result of Li et al, (2019) when they used protected methionine (3, 4.5) g / head / day in feeding male lambs of Ningxia Tan breed for 60 days, where they obtained a significant increase in the total protein concentration compared to the control group, and this may be explained by the fact that the protection protein reduces the degree of degradation it in the rumen and increases its reach to the stomach and small intestine, which an increase in the absorption of amino acids and thus increase the protein in the serum (Richardel, 2004;Ali e al., 2005). Kandil et al, (2017) reported an increase in the total protein concentration in serum as a result of methionine supplementation. Other studies did obtain significant differences such as Imik and Gunlu (2011) when using the protected methionine at 2 g /kg of diet in Morkaraman breed compared with the control group.…”

This study was conducted at the animal field of the Agriculture College / University of Basra / Karma Ali site for the period from 7/10/2019 to 1/5/2020 to investigation the effect of adding protected amino acids (methionine and lysine and their mixtures) on some physiological trails of male Arabi lambs. Sixteen male lambs with an average weight of (27.95) kg and an age of 5-6 months were selected, and randomly divided into four group (4 animals per group). The results indicated that there were no significant differences in the concentration of hemoglobin, packed cell volume, the number of red and white blood cells, cholesterol, triglycerides and the activity of the liver enzyme (ALT and AST) between the different treatments, while there was a significant (p <0.05) increase in the total protein and albumin concentration in the fourth treatment compared with the first treatment (control), while, there was a significant decrease (p <0.05) in the urea concentration for the fourth, third and second treatments compared with the first treatment. The concentrations of glucose, thyroxine and growth hormone increased significantly (p <0.05) in the fourth and second treatment compared with the first treatment. However, it can be concluded from the study that feeding the male lambs with 5g methionine or mixing it with lysine by 5g raises the concentration of glucose, growth hormones and thyroxine in the blood. Also, the levels of methionine and lysine used did not change the concentration of the studied biochemical parameters
