    EFFECTS OF ALKALI TREATMENT OF SOYABEAN ON CARCASS TRAITS, INTESTINAL MORPHOLOGY AND COOKING YIELD OF BROILERS
    (Department of Animal science,Nasarawa State University Keffi, 2013-01-01) Ari, Maikano Mohammed; Ayanwale, B.A.; Ogah, D.M.
    The effects of different alkali treatment of soyabeans on carcass traits, intestinal morphology and cooking yield of broilers was evaluated using 240 Anak broilers day-old chicks that were allocated into four (4) treatments of three (3) replicates as thus: Soaking in water (H20)- T1, sodium carbonate(Na2CO3) –T2, potash (K2CO3) –T3 and sodium hydroxide (NaOH) -T4 based groups. Five birds were selected from each group and fasted for 8 h prior to carcass evaluation. Plucked weight percentage did not vary significantly (P>0.05) among processed broilers, but significant (P<0.05) differences were recorded in the eviscerated weights. Neck, breast and primal cut-up parts varied significantly (P<0.05). No significant (P>0.05) differences were observed in the values for head, wing and shank. Intestinal weight and organs like lungs, liver, gizzard, heart, kidney spleen and abdominal fat deposition significantly (P<0.05) varied. Cooking yield was significantly (P<0.05) reduced in 1% NaOH. The best percentages for the fleshy primal cuts parts and the meat/bone ratio were 9.20% of breast in 1% Potash; 5.20% of thighs and 4.93% of drumstick all recorded in 1% Potash group and so also 4.35 ratio of meat to bone was recorded in 1% K2CO3. Alkaline treatment of soyabeans with 1% K2CO3is recommended for improved carcass yield in broilers.
