<b>Whole rice in japanese quails’ diet

Abstract

A trial was conducted to evaluate the use of dehulled and unpolished whole rice in Japanese quails' diet. A total of 100 80-days-old Japanese quails (149.07 ± 10 g) were distributed in five treatments: 0% dehulled and unpolished whole rice (control diet based on corn and soybean meal), 20, 40, 60, and 80% of whole rice in replacement of corn; respectively, treatments 1, 2, 3, 4, and 5. Productive performance was evaluated through egg production (%), egg weight (g), body weight (g), egg mass (g), feed conversion per egg mass and feed conversion per dozen eggs. The following variables measured the internal quality of eggs: albumen height (mm), yolk color and percentage, egg white percentage and Haugh units. The external quality of eggs was measured through specific gravity (g cm-3), shell thickness (μm) and shell percentage. Treatment means were analyzed through polynomial regression at 5%. As the level of whole rice was increased in the diets, a significant linear increase in egg production (p = 0.005), egg mass (p = 0.007), shell thickness (p = 0.03) and specific gravity (p = 0.007) was observed. Feed conversion per egg mass (p = 0.006), feed conversion per dozen eggs (p = 0.003) and egg color (p < 0.0001), on the other hand, were reduced linearly. The increased utilization of whole rice increased the cost of the diet. In conclusion, the addition of dehulled and unpolished whole rice in partial substitution of corn in Japanese quails' diets increases the egg production and reduces the yolk color.

Energy values and standardized ileal digestibility of amino acids in some feedstuffs for broilers

“…Freitas et al (2013) and Quevedo Filho et al 2013observed that 25 and 30% inclusion, respectively, did not affect the performance of Japanese quail in the laying phase. Gopinger et al (2015), in turn, concluded that brown rice bran can replace up to 80% of corn in the diet of Japanese quail, increasing egg production; however, it reduces yolk color due to the lack of carotenoids present in corn.…”

Ingredientes alternativos en la alimentación de codornices

“…Según Rostagno et al (2017), el arroz partido y la harina de arroz contienen 3219 y 3152 kcal/kg de energía metabolizable respectivamente. El arroz partido constituye una alternativa para su utilización en la alimentación animal por el bajo costo (Gopinger et al, 2014;Rahman et al, 2019), permitiendo que estos coproductos del arroz puedan ser utilizados en la alimentación de aves en zonas cálidas (Farias et al, 2014).…”
