Cysteine Amino Acid

This research aimed to observe the interaction of methionine-cysteine amino acid supplementation to decrease the effect of aflatoxin B1 (AFB1) on diet against production performance of broiler chicken. A number of 240 mixed sex broiler chickens were treated in 9 treatments by factorial design 3 x 3 with methionine-cysteine amino acid (M+C) (75,100, dan 125%) factors and AFB1 levels (0, 200, dan 400 ppb). Variables observed were: Weight gain, feed consumption, and feed conversion ratio (FCR). The results showed that increased AFB1 content in diet from 0 to 400 ppb increased chicken body weight (P <0.05) in each age group. The high body weight was balanced with high feed consumption along with increased nutrient needs, mainly sulfuric amino acid (M+C) as the precursor of glutathione to eliminate toxic through conjugation reactions. The interaction effect was firstly occurred between M + C and AFB1 treatment (P <0.05). Meanwhile increased supplementation of M + C from 75 to 125% caused decreased feed consumption in each age group of chickens, but increased AFB1 levels further increased feed consumption (P<0.05). The interaction effect between the level of M + C and AFB1 contamination in diets on feed consumption were seen in 21-day-old chickens (P<0.05). FCR was also increased (P <0.05) with the reduction of M + C content in diet at 7 days old. The effect of AFB1 on diet and interaction between M + C and AFB1 on chicken FCR in this study was not significant in all age groups. It can be concluded from the current study that supplying methionine-cystine amino acid with 75, 100 and 125% in AFB1 contaminated diet of 0, 200 and 400 ppb improves the performance of broiler chicken production.

Abstract Digestibility of AA in feed ingredients for pigs has been generally determined by feeding semipurified diets containing test ingredients as a sole source of nitrogen. However, malnutrition caused by feeding semi-purified diets may affect the digestibility of AA. Therefore, the hypothesis of this study was that the standardized ileal digestibility (SID) of AA in distillers’ dried grains with solubles (DDGS) are not affected by the addition of casein in experimental diets. In Exp. 1, 20 growing pigs were allotted to dietary treatments including 2 diets containing either 480 g/kg DDGS or 308 g/kg DDGS and 60 g/kg casein. The SID of Lys and Phe for DDGS in the diet containing casein were greater (P < 0.05) than those without casein. Exp. 2 was conducted with 20 growing pigs assigned to dietary treatments containing 0, 55, 110, or 165 g/kg casein while the concentration of DDGS decreased at 466.8, 311.2, 155.6, or 0 g/kg. The SID of most indispensable AA in DDGS linearly (P < 0.05) decreased with increasing concentration of casein. Experiment 3 was conducted to verify that the results of Exp. 1 were affected by the addition of casein or by the concentration of DDGS or both. Twenty growing pigs were assigned to dietary treatments prepared as a 2 × 2 factorial arrangement with the concentration of DDGS at 466.8 or 155.6 g/kg and casein at 0 or 110 g/kg. The SID of most indispensable AA in DDGS at 466.8 g/kg were greater (P < 0.01) than in DDGS at 155.6 g/kg regardless of dietary casein. Overall, the addition of 60 g/kg casein to experimental diets may increase the SID of AA in low-protein quality ingredients but the addition of higher concentration of casein and low concentration of dietary protein from test ingredients may decrease the SID of AA.
