Understanding the mechanisms that lead organisms to be separated into distinct species remains a challenge in evolutionary biology. Interspecific hybridization, which results from incomplete reproductive isolation, is a useful tool to investigate such mechanisms. In birds, interspecific hybridization is relatively frequent, despite the fact that closed species exhibit morphological and behaviou...

The objective was to evaluate the increasing levels of magnesium in water supplied laying quails (Coturnix coturnix japonica), kept climatic chambers under thermoneutral temperature and thermal stress, on their performance morphometry organs. birds were distributed a completely randomized design, 2x4 factorial arrangement, 2 temperatures (24 32 ºC) 4 (50, 150, 250 350 mg L-1), with six replicat...

The aim of this study was to describe the fauna of flies associated with captive Coturnix coturnix (L.) (Galliformes: Phasianidae) droppings. Samples of 150 g of quail droppings were exposed in the quail house for 48 h in plastic containers to promote eventual access of flies, and then placed in emergence traps. The number of adults and species emerging was recorded daily. This procedure was ca...


 The study aimed to determine the effect of adding Tenebrio molitor growth quail (Coturnix-coturnix ja- ponica). research approach is quantitative. This type experimental with a completely randomized design (CRD) consisted 4 treatments and 5 repetitions. used were P0 (control), P1 (larvae eating vegetable waste), P2 fish P3 + waste). parameters in this stu- dy consumption, growth, egg wei...

Feeding quail chicks diets containing soybeans fermented with two cultures of Aspergilli (A. oryzae N.R.R.L. 451 and A. oryzae N.R.R.L. 506) resulted in significantly superior weight gains (p less than 0.05) through a 4-week growth period and confirmed previous observations made with identical cultures in broiler studies. Subsequent hen-day egg production and egg size were changed little by die...
