Farelo de algodão na dieta de codornas japonesas

Abstract

Abst ractThe objective of this study was to evaluate different levels of inclusion of cottonseed meal in the diet of Japanese quail. Twenty Japanese quails were used in a completely randomized design consisting of five treatments and six replicates, with eight quails per replicate. The treatments used were: basal diet with 0% cottonseed meal; inclusion of 4% cottonseed meal, 8% cottonseed meal, 12% cottonseed meal, and 16% cottonseed meal. Feed intake per egg mass (kg/dz), feed conversion per egg mass (kg/kg), viability of birds, and weight gain were evaluated. The egg quality variables were: egg weight (g), yolk weight (g), eggshell weight (g) albumen weight, percentage of yolk, eggshell and albumen, and specific gravity (g/cm 3 ). Cottonseed meal in the diet influenced (P<0.05) individual feed intake (g/bird/day), yolk weight (g), albumen, and percentage of yolk, eggshell and albumen. No significant difference was observed for the other variables (P>0.05). Cottonseed meal can be added to the diet of Japanese quail without compromising performance or egg quality.

Addition of homoeopathy in the diet of Japanese quails increases egg weight

“…The data found for productivity are within the parameters cited by Ferronato et al (2020) as the conventional margin of laying of one egg per quail per day. In the present study, the average was above the reference value.…”

Calcareous seaweed flour in the diet of Japanese quails and its effects on egg conservation

“…Quail farming is considered an alternative activity for small producers due to its low initial investment, use of small areas, and low labor (BITTENCOURT et al, 2019;VALENTIM et al, 2019). However, over the years, this activity has grown and has ensured good returns to rural producers (FERNANDES et al, 2018;FERRONATO et al, 2020). Among the difficulties found in the production of quails, we can mention the quality of eggs, most notably the quality of shells, which is affected by bird age, bird nutrition, and heat stress (SILVA et al, 2018).…”
