    Dietary effect of different drying methods and graded inclusion levels of ginger (zingiber officinale) on the perfonnance and gut morphology of broilers
    (Sciencedomain International, 2016) Adeyemo, G. O.; Ogunshote, E. O.; Longe, O. G.
    The experimental design was a 3 by 3 factorial arrangement in a completely randomized design. Three hundred broilers were used for the experiment; they were randomly allotted to the ten dietary treatments with 5 replicates per treatment and 6 birds per replicate. The birds were weighed weekly to determine their weight gain, body weight and feed conversion ratio. Thirty finisher birds were sacrificed and the ileum and duodenum removed for gut histo-morphometry. Results showed that drying methods influenced performance. This was observed for the average body weight gained per bird per day while the effect of the inclusion level was observed on the feed conversion ratio. Factor interaction was observed for weight gained/bird per day and feed conversion ratio. However, only numerical differences were observed for average final body weight/bird and average feed intake /bird/day. Duodenal and ilea, villous height showed significant effect (P<0.05) of drying method, inclusion levels and treatment interaction with the control having the highest mean values. It can be concluded that supplementing broiler feed with air-dried ginger at 1.5% inclusion level can be effective as it led to an increase in the final body weight, average body weight gained per day per bird and average feed intake. No effect of drying methods and inclusion levels were observed for the histo-morphometry.

    Effect of dietary inclusion of ginger (zingiber officinale) dried with different methods on perfonnance and gut microbial population of broiler chicks
    (Sciencedomain International, 2016) Adeyemo, G. O.; Olowookere, I. J.; Longe, O. G.
    Effect of dietary inclusion of differently processed ginger on performance and microbial population of broiler chicks were investigated in a 52-days feeding trial. A total of three hundred one-day old (arbor acre) broiler chicks were used for the experiment, the birds were allotted into ten dietary treatments of five replicates and six birds per replicate in a 3x3 factorial arrangement of completely randomized design. Weights of the birds were taken weekly throughout the experimental period. Birds were fed ad-libitum such that diet 1 was the basal diet (BD) without ginger, diets 2, 3 and 4 were BD+ sundried ginger at 1, 1.5, 2% inclusion levels respectively, diets 5, 6 and 7 were BD+ air- dried ginger at 1, 1.5 and 2% inclusion levels respectively, diets 8, 9 and 10 were BD+ oven-dried ginger at 1, 1.5 and 2% inclusion level respectively. On day 52 of the experiment, the birds were slaughtered. Sections of the ileum was cut and aseptically emptied into a sterile bottle for microbial analysis. Broilers fed diets containing ginger had no significant (P> 0.05) differences on the average initial body weight, average final body weight and average daily feed intake. Although the birds fed with diet containing oven-dried ginger at 2% inclusion level had the least (P>0.05) numerical difference of the average daily feed intake. The average body weight gain and feed conversion ratio (FCR) were not significant across the dietary treatments. Birds fed diet without ginger had higher body weight gain and best feed conversion ratio (P<0.05). The total Aerobic and coliform microbial counts of broilers were not significantly (P>0.05) affected by the dietary treatments. Although the total aerobic microbial count was reduced in birds fed diets containing ginger when compared with the control.

    Haematological and Serum Biochemical response of broiler chicks fed diets containing ginger (zingiber officinale) from different processing methods
    (Department of Agricultural Extension and Rural Development, University of Ibadan, 2015-07) Adeyemo, G. O.; Olowookere, I. J.; Longe, O. G.
    An experiment was conducted with 300 one day old (arbor acre) broilers to assess their haematological and serum biochemical response when fed ad-libitum varying levels of dietary ginger from different processing methods. Ten dietary treatments were formulated such that diet 1 was the basal diet (BD) without ginger, diets 2, 3 and 4 were BD+ sundried ginger at 1, 1.5, 2% inclusion levels respectively, diets 5, 6 and 7 were BD+ air-dried ginger at 1, 1.5 and 2% inclusion levels respectively, diets 8, 9 and 10 were BD+ oven-dried ginger at 1, 1.5 and 2% inclusion level respectively. On day 52 of the experiment, blood samples were collected from the wing vein of the birds for haematological and serum biochemical evaluation. Dietary treatments had no significant differences on haematological parameters, except for the packed cell volume (PCV) and monocytes which were significantly P<0.05 influenced by the dietary treatment. Broilers fed with diet containing sun-dried ginger at 1.5% inclusion level had the highest PCV value and monocyte value. The serum biochemical indices were not significantly P>0.05 affected by the dietary treatments. However, the total cholesterol was reduced across the diets that contained ginger when compared with the control.
