Class Grow Out Project The broiler industry makes up a huge part of the agricultural sector and continues to expand with each passing day. With the cheapest price per pound and a feed conversion ratio second only to catfish, chicken is the one of the most economical viable sources of protein. With the population of the world expected to reach over nine billion people before 2050, intellectual minds must find a way to expand our current food production by almost seventy percent with the same amount of land. Auburn University students are learning everyday what concepts the broiler industry have used in order to gain larger carcass yields than fifty years prior and how the industry can still obtain more carcass yield gains. Sexual dimorphism,

At market day or day forty-two the disparity in total weight is large at almost seventy-five kilograms. Total body weight gives only a partial image of the difference and in order to see the full scale of the difference processed hot carcass weights and breasts weights must be examined. Graph 2 below contains the data for carcass and breast weights. The difference in hot carcass weights is about seventy-one kilograms and the difference in breast yield is almost thirty-one kilograms. The gap between the males and females might not look that large, but this experiment started with three hundred and sixty birds with only seventeen mortalities. In the commercial world, a typical complex process one million to about one and a half million broilers in a week’s time. Therefore, the yield difference would be huge and with more yield comes hopefully more profit. So it is important for companies to make smart and fact based decision in order to stay competitive in today’s market. However, as important as total carcass yield it is not the only thing that influences company’s decisions on what sex of broiler to grow. Feed conversion ratio or FCR is another key factor in the decision making. FCR is defined as the amount of feed consumed in order to gain one kilogram of mass. In this experiment, the male broilers consumed a total amount of eight …show more content…
For this experiment only two different stocking densities was used. Those stocking densities were thirty birds per pen or sixty birds per pen. The sixty birds per pen is close to the standard that is used in the industry today. During the experiment, rooms twelve through nine contained birds at thirty birds per pen and room eight contained the birds that were at a stocking density of sixty birds per pen. Graph 5 below shows average weight per bird in the low stocking density pens versus the high stocking density pen. As one can see the birds that were housed at a lower stocking density had a larger average body weight at day forty-two than the birds at a higher stocking density. Unlike what was proposed in the hypothesis, the birds at the higher stocking density has a large diffrence in mortality when compared to the low stocking density birds. There was a total of two moratlities out of a 120 birds in the high stocking density and a total of sixteen out of 240 birds in the low stocking density. Therefore, the higher stocking density program fared a lot better in terms of livability than the low stocking density program. This data is displayed in graph six. As well as mortality and body weight gain, FCR can be influnced by the stocking density. If there are too
