Effects of feeding different levels of dried brewery grains on egg quality parameters and laying performance

One of the key goals of poultry production is to decrease the expenses associated with feed.The by-product of brewing known as dried brewers' grains (DBG) may be a promising and cost-effective alternative to conventional feedstuff, such as maize and soybean meal.The aim of this review was to assess the impact of brewer's dried grains on the performance and quality of eggs produced by layer chickens under intensive management conditions.Fully dried grain has a dry matter content of 93%, a metabolize energy content of 2360 kcal/kg, a nitrogen-free extract content of 48.6%, and an ether extract content of 6.2%.In a study, adding BDG at a level of 18% to the chicks' diet could decrease production costs compared to the control diet, , which made it economically feasible.Moreover, it increased economic efficiency without having any negative effects on the chicks' feed intake, weight gain, or feed conversion efficiency.The quality of the albumen, yolk, and shell was unaffected by diets containing DBG.As the proportion of BSG in the rations increased, the feed cost decreased, primarily owing to its more affordable purchase price.It can be therefore concluded that adding DBG to the diet of layer chickens affects neither egg output nor quality, and it can even be financially beneficial.
