Restrição alimentar para frangos de corte

Abstract

This study aimed to conduct a literature review of food restriction on poultry production, highlighting the effects of the creation of commercial broilers. The dietary restrictions may be considered as a combined production, and this benefits the creation assisting in the reduction of paw problems, feathers, metabolic diseases such as ascites, and also the deposition of fat in the meat. To gain prominence in the market, the poultry industry had to invest heavily in methods that would alter the final product thus meeting the demands of today's consumers for more lean and healthy meats. In this scenario, the poultry production was one of the fastest growing in recent years, needing to go through many changes, particularly as regards the growth of the birds, which were genetically modified so that the animals obtain faster growth and an increase in the noble parts of the carcase as breast and thighs. It also brought negative results for the birds, because although a large body growth, its organs and its skeletal muscles did not follow this growth, leading to the aforementioned problems. To reduce these disturbances, it was necessary to use food restriction methods, which have been and are being studied for improvements that have at getting higher yields. These restriction methods can be divided into quantitative and qualitative methods, and the quantitative method is the reduction of the daily volume of feed and qualitative method is to energy restriction. These methods can also have positive and negative results in production. But it must be taken into account some important aspects so that there is success in the use of these in broiler production.
