A total of 360 1-day-old broiler chicks were randomly assigned to 4 treatments with 5 replicate cages and 18 birds per cage for a 35-day trial to investigate the effects of supplementing Achyranthes Japonica Nakai (AJN) root extract in low crude protein (CP) diet on growth performance and carcass traits. Experimental diets were divided as standard CP content diet, low CP content (LCP) diet, and LCP diet supplemented with 0.025 or 0.050% AJN root extract. Dietary CP reduction impaired growth performance and carcass traits, while supplementing AJN root extract improved growth performance and carcass traits.

Probiotic effects on growth performance, carcass traits, blood parameters, cecal microbiota, and immune response of broilers were studied. Two hundred one-day-old male chickens were allocated to one of five treatments (four replicates of 10 birds per treatment): control, and the same control diet supplemented with 0.005%, 0.01%, 0.015% and 0.02% probiotics. Probiotics in feed at 0.01% or higher levels of supplementation improved body weight gain (+12%) and feed conversion rate (-5%) compared with the control. There were no effects on carcass traits, but the relative weights of drumsticks and wings showed increasing and decreasing linear responses, respectively, to probiotic supplementation level. Blood plasma glucose and albumin contents linearly increased (from 167.1 to 200.5 mg dl-1, and from 1.70 to 3.25 g dl-1) with increasing probiotic supplementation. Triglycerides and cholesterol contents were lower in probiotic supplemented treatments (average contents 71.3 and 125.3 mg dl-1 vs. 92.6 and 149.9 mg dl-1 in the control). Probiotics decreased cecal Escherichia coli counts, but had no effects on immunity related organs or immune response. The linear trends, either positive or negative, observed in many of the parameters studied, suggest that more studies are needed to establish the optimal concentration of probiotics in broiler feed.

The study determined the effect of three different levels of Boswellia serrata tree resin (BSR) supplementation in diets for broiler chickens on the growth performance, selected slaughter analysis, nutrient digestibility, as well as haematology, biochemical and some humoral immunity blood parameters. In total, 200 1-day-old broiler chickens were assigned randomly to four treatments. The broiler chickens were fed diets containing 0 (C), 1.5 (BSR1.5), 2 (BSR2), or 2.5% Boswellia serrata resin (BSR2.5). The BSR treatments improved (P < 0.05) the feed intake and feed conversion ratio at breeding Days 22–35, but did not differentiate the nutrient digestibility in the diets. The best-quality carcass with a high proportion of muscles and low fat content (Control versus BSR diets, linear, P < 0.05) was obtained in broiler chickens fed diets supplemented with 2% and 2.5% BSR. The blood profile was affected by the BSR treatments. The lymphocyte count increased linearly in blood (P < 0.05) along the increasing amounts of BSR. The content of uric acid and aspartate aminotransferase activity in blood plasma decreased upon the BSR supplementation (Control vs BSR diets, linear, P < 0.05; and Control vs BSR diets, linear, P < 0.01, respectively). The resin of Boswellia serrata can be considered as a good botanical feed additive, which can have positive effects on the performance and health of broiler chickens.
