Animal Feed Science and Technology · 2020 · 37 citations
The addition of phytase enzyme to broiler feed as a means of improving phosphorus (P) availability and reducing P excretion is widespread practice. New phytases with enhanced functionality continue to be developed. We tested the effects of a next generation biosynthetic bacterial 6-phytase on growth performance, tibia ash and P digestibility in broilers. Treatments included a nutritionally adequate positive control (PC) diet, a negative control (NC) diet formulated with reductions in Ca and avai…
Effect of the addition of ultraviolet light on broiler growth, fear, and stress response
The Journal of Applied Poultry Research · 2020 · 35 citations
Senior authorCorrespondingThe objective of this study was to determine the effects of ultraviolet light supplementation on production parameters, fear responses, and stress susceptibility in broiler chickens. Birds were reared under either light emitting diode (LED) bulbs supplemented with UV light fixtures (UV) or just LEDs (Control). Growth, feed conversion, tonic immobility, inversion, composite asymmetry, plasma corticosterone, heterophil-to-lymphocyte ratio, and humoral immunity were measured to determine treatment…

Senior authorCorrespondingSeveral feed additives such as synbiotics and organic acids may be viable options for controlling Salmonella in poultry. This experiment was conducted to study the effects of synbiotic product or synbiotic plus enhanced organic acid program on broiler performance, intestinal histomorphology, and cecal and carcass Salmonella load. A total of 648 day-of-hatch Cobb 700 male broiler chicks were randomly allocated to one of 4 dietary treatments: basal control diet (CON), CON diet supplemented with a…

articleOpen access1st authorCorrespondingHeat stress is one on the main welfare issues that broiler chickens face and it can lead not only to decreased welfare but production as well. The seaweed Ascophyllum nodosum has demonstrated the ability in several species to decrease body temperature and affect immune function. To determine whether adding an extract of this seaweed into the diet of broiler chickens would decrease the negative effects of prolong heat stress on broiler growth, a study was conducted. Broilers were fed a control di…

articleOpen accessThe capacity of combinations of feed enzymes, natural betaine and a probiotic, combined with alternative plant-based ingredients, to totally replace soybean meal (SBM) in a broiler diet was evaluated. Day-old Ross 308 males (2,574) were assigned to 9 treatments (13 pens/treatment, 22 birds/pen) in a completely randomized design. All diets were pelleted and fed ad libitum in 4 phases: starter, grower, finisher 1, finisher 2 (0-10, 10-21, 21-35, and 35-42 d of age, respectively). Treatments includ…
