Effects of cocktail enzymes supplementation on performance and gut morphology of arbor-acre broilers fed low density diets based on corn-soyabean meal
(International Academic Journal, 2014-09) Adeyemo, G. O; Awolesi, M. E; Adebiyi, O. A.
The effect of maxigrain cocktail enzyme on performance and gut morphology were investigated in a 42-day feeding trial. A total of 240 one-week-old arbor-acre broiler chickens were fed the following diets at the finisher phase: Treatment 1 (T1): 21% CP+3000 kcal/kgME-Enzyme, Treatment 2 (T2): 21% CP+3000 kcal/kgME+Enzyme, Treatment 3 (T3): 21% CP+2600 kcal/kgME-Enzyme, Treatment 4 (T4): 21% CP+2600 kcal/kgME+Enzyme, Treatment 5 (T5): 17% CP+3000 kcal/kgME-Enzyme, Treatment 6 (T6): 17% CP+3000 kcal/kgME+Enzyme. The experimental design was a completely randomized design. The birds were randomly assigned to six (6) dietary treatments of 4 replicates each and 10 birds per replicate. The birds were fed ad-libitum and were weighed on a weekly basis to determine their growth performance. On day 42, four birds were slaughtered and sections of the duodenum, ileum and jejunum (1 cm) were removed for gut histomorphology. Maxigrain enzyme supplementation significantly increased the performance (average body weight again (ABWG), total average feed intake (TAFI)) especially with birds on treatment 1 (T1) and treatment 2 (T2). Although, birds fed treatments 4 (T4) compared favourably with those on treatment 1 (T1). Enzyme supplementation had significant (P<0.05) effect on the villus height (VH), crypt depth (CD), villus width (VD), muscular width (WD) and the villus to crypt depth ratio (V:CD) of the birds duodenum, jejunum and ileum sections across the treatments. These dietary supplement had significant (P<0.05) effect on the villus height (1629.00 µm-5620.00 µm (duodenum), 1731 µm-6851 µm (jejunum), 1149 µm-5061 µm (ileum)), crypt depth (155.00 µm-641.10 µm (duodenum), 214.40 µm-873.60 µm (jejunum), 158.60 µm-751.10 µm (ileum)), villus width (148.40 µm-426.30 µm (duodenum), 151.00 µm-538.10 µm (jejunum), 131.60 µm-675.50 µm (ileum)) and muscular width (421.70 µm-1347.30 µm (duodenum), 445.30 µm-1347.30 µm (jejunum), 334.30 µm-1584.60 µm (ileum)) and the villus to crypt depth ratio (7.90-12.03 (duodenum), 7.84-9.83 (jejunum), 6.02-11.21 (ileum)). Effect of enzyme inclusion better increased the histomorphometric parameters measured of bird's duodenum, jejunum and ileum particularly of birds on T4. The villus to crypt depth ratio of bird's duodenum section fed T2 and T6 were increased by enzyme supplementation however, there were decreases in the jejunum and ileum sections of birds fed T2 and T4. Maxigrain cocktail enzyme resulted in improved growth performance and gut morphology of broiler birds fed low energy diets, giving a cost-effective nutritional strategy for profitable broiler production.
Optimizing the utilization of soybean and benniseed (in poultry feeds) through dietary supplementation with microbial phytase
(Animal Science Association of Nigeria, 2006) Ologhobo, A. D.; Mosenthin, R; Adeyemo, G. O
The effects of microbial phytase (Natuphos® 5000) supplementation of corn-soybean and benniseed based diets were studied with two weeks old broiler birds on the parameters of growth performance, nutrient retention, and amino acid digestibility. One hundred and twenty chickens within a weight range of 190 to 210g were allotted in a completely randomised 2 x3 factorial arrangement to six dietary treatments. Body weight gain (g) 1074.17 + 12.26, feed intake (g) 1913.17 ± 15.60 and protein efficiency ratio 2.54 ± 0.16 were significantly (p '< 0.05) increased by phytase supplementation of soybean meal and benniseed diets. Significant (p •: 0.05) increases were also obtained for apparent retentions of dry matter (DM) 68.68 ± 3.72, nitrogen (N) 56.21 ± 2.83, phosphorus (P) 39.00 ± 2.14 and calcium (Ca) 58.78 ± 3.16 and apparent faecal digestibilities of protein (%) 8.11 ± 56 and amino acids. There were however significant (P • 0.05) differences in the magnitude of response by soybean meal and benniseed to phytase supplementation. For soybean meal diets, apparent retentions of N 55.74 ± 2.83 and p 37.88 ± 2.14 and protein digestibility 00.36 ± 1.20 increased-rapidly (p ■ 0.05) with 400 FTU/kg phytase but marginally with 800 FTU/kg phytase. On the contrary for benniseed diets, supplementation with 400 FTU/kg phytase increased amino acid digestibility marginally while 800 FTU/kg phytase significantly (p < 0.05) increased the digestibility of all amino acids.
Potentials of ethanolic extracts oe (jatropha curcas) on the gut morphology of broilers
(International Academic Journal, 2014) Adeyemo, G. O; Oluyede, F. A.
In a study conducted to evaluate the effect of Jatropha curcas leaf extract on the gut morphology of broiler chickens, one hundred and fifty day old Arbor Acre broiler chicks were randomly allocated to five treatments, each replicated five times, with six birds per replicate over a period of forty two days. The birds were allocated to the following treatments (T): T1 (Negative control, no antibiotics), T2 (positive control, with antibiotics), T3 (0.25g/100kg Jatropha curcas leaf extract), T4 (0.50g/100kg J. curcas leaf extract) and T5 (0.75g/100kg J. curcas leaf extract). Samples were collected from the ileum and duodenum for gut morphology assay, with the results of gut morphology revealing that J. curcas supplementation improved villi height in duodenum (p<0.05), while significantly decreasing values for villi height in the ileum (p<0.05). Crypt depth values were also significantly influenced by inclusion of antibiotics and 0.25% J. curcas extract.
