Abstract
Effects of dietary coconut oil meal with or without an enzyme mixture on laying performance and physical parameters of eggs of Japanese quail (<em>Coturnix coturnix</em>)
Highlights
Feed cost accounts for more than 70% of the total recurrent cost of production and greatly influences the profitability of quail production and the affordability of meat or eggs to consumers
The level of coconut oil meal (COM) or supplementary enzyme had no significant effect on birds live weight (Table 2)
Feed intake and the total egg production of the quail fed with 10% COM incorporated diet was significantly higher than those of quails fed diet incorporated with 0% and 20% COM
Summary
Feed cost accounts for more than 70% of the total recurrent cost of production and greatly influences the profitability of quail production and the affordability of meat or eggs to consumers. Locally available agricultural by-products such as coconut oil meal or copra in diets at higher levels, replacing ingredients such as soybean meal and maize meal could reduce the feed cost while minimizing adverse environmental impacts associated with livestock, including quail. Nutritive value of coconut oil meal has been reported to be poor due to low concentrations of several limiting amino acids, high levels of dietary fiber and non starchy polysaccharides, and the rancidity (Sundu et al, 2006). Panigrahi et al (1989) found no adverse effects of 20% COM on laying performance of chicken whereas Moorthy and Dietary Coconut Oil Meal on Laying Performance of Japanese Quail. Objective of this study was to determine the effects of incorporation of COM upto 20% with or without an enzyme mixture (BIO-GRAIN CG) on egg production of Japanese Quails
