Abstract
The study investigated the effect of alkali-treated groundnut shell meal on the growth rate and nutrient digestibility of broiler birds. One hundred and eighty 28-day old Anak 2000 broilers chicks were utilized for the experiment which was randomly allocated to the five dietary treatments at the rate of 36 birds per treatment with 4 replications. All experimental birds were given weight amount of feed and water was provided ad libitum under standard management practices. Fifty kg of groundnut shell (GS) was soaked in 750 litres of water with 3kg of potash for 3 days. The shell was afterward, sieved, sundried, ground and supplemented in the diet tagged PTGSM. Same procedure was repeated for salt (STGSM) and alum (ATGSM). The chick diets were compounded to be isocaloric(about 2990 kclg-1ME) and isonitrogenous (about 22%CP); the result showed that final weight (1975 vs. 1600.00 vs. 1775.22 vs. 1616.29 and 1454g/bird), weight gain (48.13 vs. 34.04 vs. 38 57 vs. 33.34 and 28.38g/bird/day) and FCR (4.54 vs.5.21 vs. 6.09 vs. 4.35 and 4.21) were significantly (P<0.05) influenced for control, PTGS, ATGS, STGS and UTGS diets, respectively. Same processing methodwas repeated for the finisher phase (28-56days) with adjustment on the energy and protein contented to be about 2700 kclg-1ME and 20%CP, respectively and their growth rate and nutrient digestibility determined. The result showed that birds fed the control diet had the heaviest (P<0.05) final weight (1975 g/bird), while those fed the control and ATGS gained more (P<0.05) weight (48.13 and 38 57 g/bird/day) and FCR was better for birds fed the PTG and ATGS (5.21 and 6.09). Crude fibre digestibility was better (P<0.05) in birds fed the PTGS, (55.25%), ATGS (55.13%), STGS (55.64%) and UTGS (55.23%) than those fed the control diet; neutral detergent fibre digestibility was better in birds fed the ATGS (44.37%), STGS (41.96%) and UTGS (43.54%) while birds fed the PTGS, ATGS and STGS had better (P<0.05) acid detergent lignin digestibility (65.33 vs. 67.94 and 68.34%).From the findings of this study, farmers can use PTGSM for poultry production without any adverse effect on the growth rate and meat of broilers.
