Impact of sodium humate on performance, rumen microbial and faecal egg counts of West African dwarf goats fed cassava peel based diets
The problem of cyanide poisoning may be addressed with addition of feed additives with potentials for detoxification. This research was conducted to assess the performance, rumen microbial and faecal egg counts of West African dwarf (WAD) goats fed cassava peel based diets. Twenty WAD bucks were fed cassava peel based diets supplemented with sodium humate at 0, 5, 10 and 15 g/kg diet for a period of 87 days. The experiment was laid out in a completely randomised design. Data was collected on growth performance indices, rumen microbial count, apparent nutrient digestibility and faecal egg count and statistically analysed using SPSS. Results showed addition of sodium humate to cassava peels based diets improved (p<0.05) daily weight gain, feed conversion ratio and dry matter digestibility. Faecal egg count in WAD goats decreased (p<0.05) with addition of sodium humate in the diet. Increasing amount of sodium humate linearly decreased (p<0.05) protozoa count in the rumen of WAD goats. In conclusion, 5 g/kg diet of sodium humate is sufficient to ensure improved performance of WAD goats on cassava peel based diets.
