ABSTRACT: Sixteen West African Dwarf (WAD) goats of mixed sexes, aged between 5 -7 months of age and having an average weight of 6.80 kg were used to assess the nutrient digestibility and intake of diets containing graded levels of sweet orange peel meal (SOPM) in a completely randomized design. Four diets A, B, C and D containing 0%, 12.5%, 25% and 50% SOPM respectively were formulated and fed to the WAD goats for 84 days. Results show that there was no effect (p>0.05) of treatment on dry matter, organic matter, crude protein, crude fibre, nitrogen free extract and ether extract digestibility of WAD goats. Nutrient intake was also not affected (p>0.05) among the treatment groups except ether extract intake where treatments A, B, and C were significantly higher (p>0.05) than treatment D, while between treatment A, B and C there was no difference (p>0.0). The study shows that SOPM can be used to replace maize offal up to 50% without negative effect on nutrient digestibility and intake of WAD.

ABSTRACT: Four types of sweet orange peel meals: Ibadan sweet peel meal (ISPM), Valencia peel meal (VPM), Washington peel meal (WPM) and composite sweet orange peel meal (CSOPM) were assessed using the in vitro gas technique. The proximate constituents were analysed, and also milled samples of the four types of sweet orange peel meals in triplicates were incubated using 200mg/30ml innoculum for 24hrs. At post incubation, total methane gas produced was measured using 4 ml of 10M NaOH. The metabolizable energy (ME), organic matter digestibility (OMD) and short chain fatty acid (SCFA) were estimated. Dry matter was highest in CSOPM (87.66%) and lowest in WPM (80.50%), while crude protein (CP) and nitrogen free extract (NFE) values were highest in WPM (9.95% and 69.28% respectively). In vitro gas production volume (IVGP), ME, OMD and SCFA were not significantly different (p>0.05) among the sample types. However, absolute values showed that WPM had highest values of IVGP (48.33ml/200mgDM), ME (9.36MJ/kgDM), OMD (66.71%) and SCFA (1.09mmol/200mgDM). The potential extent of gas production 'b' of WPM (75.82ml/200mgDM) was significantly higher (p<0.05) than the other peel meal types and VPM (36.86) was the lowest. The potentially degradable fraction 'a+b' for WPM (81.96ml/200mgDM) was significantly higher than all the other peel meal types, while VPM (44.72) was the least. The rate constant 'c' of VPM, WPM and CSOPM were similar (p>0.05) among the treatments.

ABSTRACT: The nutritive value of four diets containing different levels of sweet orange peel meal (SOPM), D1(0%SOPM), D2(12.5% SOPM), D3(25% SOPM) and D4(50% SOPM) were evaluated in terms of their chemical composition, in vitro gas production (IVGP), metabolizable energy (ME), organic matter digestibility (OMD), short chain fatty acids (SCFA) and in vitro gas production characteristics. Results showed that the in vitro gas production characteristics did not show any significant difference (p>0.05) among treatments. The values for potential gas production 'b' and the potentially degradable fractions 'a+b' for all the dietary treatments were similar (p>0.05), but absolute values of D4(50% SOPM) for 'b' and 'a+b' (30.88 and 38.59) respectively, were higher than those of D1, D2 and D3. The rate of fermention 'c' was also similar across the treatments. In vitro gas production volumes were significantly affected (p<0.05) among the treatments. Metaboliazable energy for D4(6.56MJ/kgDM) was significantly higher than D1(5.30 MJ/kgDM), D2(5.32 MJ/kgDM) and D3(5.39 MJ/kgDM). The OMD and SCFA followed the same trend.
