Mating ratio is the ratio of males to females in a population kept for breeding purpose. It is also called sex ratio and one of the major factors for the productive and reproductive performance of each and every species of animals but also an important determining factor for cost economics for rearing. Quails (Coturnix sp.) are generally kept for egg production in Far East and Asian Countries, while they are reared primarily for meat production in European and American Countries. Quails are also used as laboratory birds because of their short life span and small size. Mating ratio affects lots of traits like productive traits, reproductive traits and some other parameters also either directly or indirectly, alone or in combination with other factors in quails as well as other avian species and animals. Besides the other effects the major and important one are observed in fertility and hatchability of eggs. Number of results found by different scientists but most of the studies observed that higher mating ratio (1:1 to 1:3) performed better than lower mating ratio (1:4 to 1:7) in terms of egg production. Similar results were recorded from most of the researchers for the hatched chick weight and fertility while the others found just opposite results for fertility. But for hatchability trait and embryonic mortality the results have so many variations with majority of non significant difference among the different mating ratios. There are very less literature were found on the effect of mating ratio on carcass traits and behavioral traits while the not a single literature was recorded for the effect of mating ratio on feed intake, feed conversion ratio and cost economics for rearing for extra males in breeding group/population. This review summarizes how mating ratio affect the number of economic traits of quail. The aim is to emphasize the role of mating ratio in quail farming and lots of future needs and scopes for the research works in that field.
