ABSTRACT Different levels of glycosaminoglycans (chondroitin sulfate and glucosamine sulfate) and vitamin C were injected in ovo to determine whether additive use influences the incubation parameters and bone characteristics of posthatch chicks. Hatchability was not affected by addition of glycosaminoglycans and vitamin C in ovo. However, chicks that received 4 μg additive showed 2.86% reduction in total mortality when compared with chicks from non-injected eggs. Moreover, tibia area and femur bone mineral density increased in chicks from eggs injected with […]

An experiment was conducted to evaluate the influence of two vitamin D sources and three vitamin C levels on performance, internal and external egg quality, and bone strength characteristics. In addition, the total and ionic blood calcium concentrations, bone ash and calcium were determined. Two hundred and eighty eight 23-week-old ISA Babcock B-300® laying hens were used during the 12-week study in a 2 × 3 factorial arrangement: vitamin D sources (cholecalciferol and 25-hydroxycholecalciferol – 25(OH)D3) and vitamin C levels […]

In order to prepare tilapia for winter, it were evaluated the effect of two levels of lipid (8.0 and 12.0%) and three levels of vitamin C (300.0; 600.0 and 1,200.0 mg of vitamin C/kg diet), with four replicates each treatment, plus two treatments, absent of test nutrients supplementation and supplemented with 6.0% of lipid and 125.0 mg of vitamin C/kg diet on growth performance and physiologic parameters during 112 days. It was utilized 192 fingerlings, with average weight of 5.57 […]
