Abstract :  The current experiment was conducted to examine the impact of a supplement of microalgae insert ignore into journalissuearticles values( Schizochytrium limacinum ); on the performance, rumen fermentation, and blood metabolites in lambs during summer. Forty lambs were used in a 49-day experiment. The lambs were group-fed either a basal diet insert ignore into journalissuearticles values(alfalfa hay and concentrate, n = 20); or the basal diet along with 5 g/day microalgae insert ignore into journalissuearticles values(n = 20);. Feed intakes were recorded daily and body weight insert ignore into journalissuearticles values(BW); was measured weekly. Overall, microalgae feeding increased insert ignore into journalissuearticles values(P < 0.05); the BW and average daily gain. There were no significant differences for average feed intake or feed efficiency insert ignore into journalissuearticles values(P > 0.05);. Microalgae feeding decreased rumen pH insert ignore into journalissuearticles values(P < 0.05); and tended to reduce proportion of acetate insert ignore into journalissuearticles values(P < 0.1);, while it increased total rumen volatile fatty acid concentration insert ignore into journalissuearticles values(8.6%; P < 0.01); and proportions of propionate insert ignore into journalissuearticles values(13.9%, P < 0.01); and valerate insert ignore into journalissuearticles values(P < 0.01; 26.5%); compared with the control animals. Microalgae feeding increased insert ignore into journalissuearticles values(P < 0.05); blood glucose insert ignore into journalissuearticles values(98.47 vs. 84.97 mg/dL); and insulin insert ignore into journalissuearticles values(64.14 vs. 29.26 ng/mL);, whereas it lowered total cholesterol concentrations in blood insert ignore into journalissuearticles values(62 vs. 58 mg/dL, P < 0.1); compared with the control animals. The results of this study indicate that microalgae supplement influences productivity and enhances dietary energy utilization in lambs during the summer.
