| Abstract |
This study was carried out in order to study the possibility of incorporating raw or treated guava by-product in broiler finisher diets. Guava by-product was collected from Vignobles Gianclis Company after that were dried and ground Guava by-product was boiled in water for one hour boiled in alkaline solution 0.1 N for one hour, boiled in acid solution 0.1 N for one hour, and autoclaved for 20 minutes at 15 1P pressure. Chemical analysis was conducted on both raw and treated guava byproduct samples.
Results showed that raw, autoclaved, alkaline and acid treated contained 9.08, 7.45, 6.17% and 9.05% crude protein, 10.0, 7.4, 5.5 and 4.8%, ether extract 39.5. 49.4, 53.3 and 47.9%, crude fiber. 32.97, 28.0. 26.04 and ,29.46% N- free extract and 2.55. 2.25, 3.01 and 2.68% ash, respectively.
The ME values ranged between 1206 to 2226 Kcal/kg respectively.
Three hundreds and fifteen broilers at four weeks old were used in feeding experiment. The chickens assigned to 21 experimental diets in three replicates of 5 chickens each. The first experimental diet (control). while other twenty experimental diets contained raw and the treated guava byproduct with the following percentage 2%, 4%, 6% and 8% at the expense of the control diet.
Results showed that the experimental diets had no significant effect on body weight and body weight gain through out the experimental period 1ncreasing level of whether raw or treated guava by-product had a significant effect on feed intake, protein intake and energy intake. when compared to those of the control diet. Feather score was not affected by the level of inclusion or by the treatment of the guava by-product. Mortality rate was affected by dietary treatment however the level of inclusion, the 6 or 8 % significantly increased the mortality rate.
There were no significant effects due to dietary treatment and levels of inclusion on carcass weight, relative weights of drumsticks or thighs and gizzard + proventricul weights. There were no significant interaction (processing X level) on relative weight of breast. back, drumsticks and thighs. No significant differences, in the relative abdominal fat weight for broilers receiving 2, 4 or 6 % raw or treated guava by-product. However, broilers received 8 % raw or treated guava by-product have significantly less abdominal fat than those received other dietary levels or the control.
Feeding high levels' of the studied by-product (4, 6 and 8%) resulted in increased relative weigh and length of intestine and cecum length.
Data from the present study indicate that up to 4 % level of Sun-dried raw guava by-product containing diet could be utilized effectively by finisher broiler chicks without adversely affecting on performance parameters.
