The objective of the present study was to evaluate the effect of using microminerals in organic form on the performance and quality of eggs from commercial laying hens at the end of laying. Four hundred and eighty Hisex strain hens, 72 to 80 weeks of age, were used. A randomized complete design was used, with six replications and 16 birds for each experimental unit. Five diets were evaluated: basal feed supplemented with all microminerals in inorganic form (control); basal feed […]

This experiment was conducted to evaluate the effect of inclusion of coconut meal (CM) in diets on nutrients digestibility, performance and egg characteristics of commercial laying hens. A total of 150 laying hens, with 76 weeks of age was weighed and allotted to a completely randomized design with five treatments and five replicates of six birds in each experimental unit. Five diets were evaluated, one control, without CM and the others with 5, 10, 15, and 20% of CM. Diets […]

This experiment was conducted to evaluate the effect of inclusion of cashew nut meal (CNM) in diets on nutrient digestibility, bird performance and egg characteristics of Japanese quails. A total of 270 japanese quails with 17 weeks of age were weighed and distributed into a completely randomized design with six diets and nine replicates of five birds in each experimental unit. Treatments consisted of one diet without CNM (control) and five diets containing 4; 8; 12; 16 and 20% of […]
