Abstract
ABSTRACT The subject of this study was to figure out the effects of lentil by product (LP) on growth performance and carcass traits of the white heavy turkeys. To accomplish this goal, a total of 210 day old big-6 turkey chicks were used. The birds were divided into 7 seven groups with 3 replicates. The 1st, 2nd, 3rd, 4th, 5th, 6th and 7th groups received 0, 5, 10, 15, 20, 25 and 30 % lentil by product, respectively. All the diets were made as izonitrojenic and izocaloric. The highest live body weights of males and females were observed in the control group at the end of the 15th week, which was the time of slaughtering of females, however the differences between the control and the 2nd, 3rd and 4th groups were not significant (p>0.05). The same differences continued for males at the end of the 17th wk of age, which was the time of slaughtering of males. Similar results were observed in carcass traits, as well. The best FCR was noted in the control group and it was significantly (p<0.05) different than in the treatment groups. The lowest and highest feed intake was observed in the 7th and 3rd groups. No significant differences were observed between control and all treatment groups. As a result, it could be said that lentil by product could be added into turkey diets up to 15% with no negative effect on live body weight and carcass traits because there was no significant differences between control and treatment groups (5, 10,15 % LP).
Highlights
Feed is the single greatest cost of poultry production
The effects that derive from the incorporation of lentil byproduct (LP) in turkey diets on bird performance, carcass traits, feed intake and feed conversion ratio under an intensive production system remain largely unknown
An experiment was conducted to evaluate the importance of fattening performance carcass traits, feed intake and Feed conversion ratio (FCR) of turkeys
Summary
Feed is the single greatest cost of poultry production. In poultry diet, corn and soybean meal are most widely fed energy and protein sources, respectively, in North America, Europe and Australia and soybean meal drastic increases in feed cost over the last decade have reduced profit margin of poultry production. Lentils are separated according to color by a special machine After this processing, if lentils suffered from quality problems such as discoloration, frost damage, or seed damage (Çabuk et al 2014), these by products become occasionally available to the animal feed industry. If lentils suffered from quality problems such as discoloration, frost damage, or seed damage (Çabuk et al 2014), these by products become occasionally available to the animal feed industry These issues do not pose any problems when such lentils are fed to nonruminant animals like poultry and pigs of all ages (Mavromichalis, 2013). As far as we couldn’t find any research about the effect of lentil byproduct on turkey growing performance. To figure out the effects of different levels of lentil byproduct on growth performance and carcass traits of Big-6 white heavy turkeys was the aim of this study
