Abstract

The aim of this study was to evaluate the inclusion of 50% broken rice (BR) in diets for meat quail from 1 to 35 days old, starting at different ages. A total of 875 mixed quail were allocated to five treatments in a completely randomized design with five replicates of 35 birds. The treatments consisted of a maize- and soybean meal-based control diet and four other similar diets in which the inclusion of 50% BR was started at different ages, namely, 1st, 8th, 15th and 22nd days. Feed intake, weight gain, feed conversion and mortality rate were evaluated weekly. At 35 days, 10 quail per plot were weighed and selected to be slaughtered for evaluations of live weight, carcass yield and gizzard yield. Lastly, a study of economic viability was carried out. No significant difference (p > 0.05) was detected for the performance parameters, live weight or carcass yield, but a higher gizzard yield was found (p < 0.05) in the treatment without BR. The inclusion of BR from the first day of life provided better economic viability. Diets with a maximum inclusion of 50% BR can be formulated for meat quail at any age.

Highlights

Feeding accounts for the costliest production factor in quail farming
There is no information on the sudden replacement of maize with broken rice at a certain bird age, considering that, in practice, the producer may apply this type of substitution whenever the price of maize rises
Maize and broken rice have relative differences in their chemical composition that may reflect on the intestinal physiology of animals and, on their production performance

Summary

Introduction

The energy component is the second factor that most elevates the cost of a diet, only after protein. In this respect, numerous alternative feedstuffs have been the object of study to ensure effective animal nutrition with satisfactory performance, at a low cost. The processing of rice generates a waste called ‘broken rice’, whose chemical composition is similar that of the polished grain and which has the potential to replace (fully or partially) maize in the diet of quail (Filgueira et al, 2014). Maize and broken rice have relative differences in their chemical composition that may reflect on the intestinal physiology of animals and, on their production performance
