EFFECT OF USING BLACK PEPPER AS NATURAL FEED ADDITIVE ON PERFORMANCE AND CARCASS QUALITY OF BROILER CHICKS
Journal Title: Int J of Preclin & Pharm Res - Year 2014, Vol 4, Issue 2
Abstract
ABSTRACT The effect of feeding broiler chicks on diets containing different levels of black pepper as natural feed additive on productive performance, carcass characteristics and economical efficiency were studied. A total of one hundred and sixty, one-day old, unsexed (Hubbard) broiler chicks were randomly divided into four experimental groups. Each group was further subdivided into five replicates at the rate of eight chicks per pen in a complete randomized design. The chicks were fed on two basal diets (starter and finisher). The black pepper (Piper nigrum L.) was added to the basal diets at levels (0.0, 0.5, 0.75 and 1%) resulting in four (A,B,C and D) formulae respectively ,with group A serving as control. The experimental diets were fed for 6-weeks duration. Health of the stock and performance parameters was recorded. Dressing, edible giblet (liver, heart and gizzard), commercial cuts percentages (breast, drumstick and thigh) and economical evaluation were calculated. The result indicated group supplemented with (1%) black pepper had significantly (P<0.05) heaviest values for body weight gain, feed intake, dressing, best feed conversion ratio, and commercial cuts percentages (breast, drumstick and thigh). The birds fed on the control group produced significantly (P<0.05) highest abdominal fat percentage. The mortality rate and the percentages of edible giblets (liver, heart and gizzard) were not affected significantly (P>0.05) by the addition of the black pepper on broiler diets. Birds fed on the highest level of black pepper (1%) yielded the highest net profit as compared to other experimental groups. Keywords: Natural feed additive, Black pepper.
