For improved outcomes on the birds and to improve quail farming in Nigeria, components to be added to the poultry feed used to breed quail birds are needed.
The goal of this study was to use two (2) weeks old Japanese quail to perform a twelve-week feeding trial to assess the effect of feeding varied amounts of Ocimum gratissimum on growth and egg size (Coturnix coturnix japonica).
Materials and Methods: In a completely randomised design experiment, 120 birds were assigned to four dietary treatment groups, each with three (3) replicates of ten (10) birds. The feeding ratios were Control (C) containing 0 g/kg; T1, 20 g/kg; T2, 40 g/kg; and T3, 60 g/kg of dried and ground Ocimum gratissimum. Throughout the trial, the animals were given unlimited amounts of food and water.
As a result of weight loss, T1, (20 g/kg) had the highest values (122.56 g, 234 percent, 0.623 and 23.49 respectively) while T3, (60 g/kg) had the lowest values (81.92 g, 156 percent, 0.487, 34.92 respectively) for weight gain (WG), percentage weight gain (PWG), specific growth rate (SRG), and feed conversion ratio (FCR). However, the C, (0 g/kg) had the greatest protein efficiency ratio (PER) of 9.149, while the T3, (60 g/kg), had the lowest (5.535). T2, (40 g/kg) had the greatest mean egg weight, length, and width values (10.01, 8.77, and 7.81, respectively), whereas T1, (20 g/kg), had the lowest (8.84, 7.63 and 6.70 respectively). The response criteria that were watched, recorded, and submitted to Anova and T-test were weight increase, feed utilisation indices, and egg size. Mean weight gain, percentage weight gain, specific growth rate, food conversion ratio, protein efficiency ratio, and circumference of the widest point of the eggs at long axis (length) showed significant differences (P0.05), whereas weight of eggs and circumference of the widest point of the eggs at short axis showed no significant differences (P>0.05) (width).
Conclusion: Quail birds given T1, (20 g/kg), produced results with no harmful effects on the birds and can be recommended in Japanese quail diets, according to this study.
