(Received 11/02/2020, accepted 29/03/2020) DOI. 10.21608/ejvs.2020.23856.1151 ©2020 National Information and Documentation Centre (NIDOC) Introduction The semi-intensive system has been reported to be the most common system of production for West African Dwarf (WAD) goats in most part of sub- Saharan Africa [1], with improved performance when compared to the extensive system and less labour input in comparison to intensive system. Given the above scenario, it cannot be said that this system is without challenges. One of such challenges is the poor quality of the forages these animals graze given that they become lignifed as the season progresses from the rainy to the dry seasons.. This has posed to be a challenge on the performance of the animals.

Vol. 51, No. 2, pp. 263-270 (2020) Egyptian Journal of Veterinary Sciences https://ejvs.journals.ekb.eg/ 29 has reported that the cause of low production rate from local goats is primarily due to poor feeding practices and lack of intensifcation of the production system have reported it. Feeding practices aimed at improving the utilization of these forages will help to improve the performance of the animals. Poor quality forages such as mature grass, may be improved by physical, chemical or biological treatment. One of such procedure is supplementing with feed materials that will modify the rumen environment in order to improve utilization of the forages. Extensive research has been performed on the effectiveness of feed supplements that P OOR quality forages such as mature grass could be improved by physical, chemical and biological treatment. One of such procedure is supplementing with feed that will modify the rumen environment to improve forage utilization. A 90-day study was conducted to ex- amine the rumen ecology of semi-intensively raised West African Dwarf (WAD) goats fed supplemented concentrate diet containing incremental levels of sodium humate. The thirty (30) WAD bucks (age 10-15 months) used in this study were randomly assigned to fve dietary treat- ments containing 0, 5, 7.5, 10 and 12.5 g/kg diet of sodium humate in a completely randomized design. Data were obtained on rumen pH, ammonia nitrogen, total volatile fatty acids (VFA) and some of their various proportions (Acetate, propionate and butyrate), protozoa, fungi and bacteria counts and were statistically analysed using the GLM procedure of SPSS (version 23). Results revealed that pH, NH3-N, and fungi count were affected (p<0.05) by the inclusion of sodium humate in the diets. However, volatile fatty acids and the various proportions, protozoa and bacteria counts were not affected (p>0.05) by the inclusion of sodium humate in the diets. It was concluded that sodium humate could be used in the diet of semi-intensively managed WAD goats to stabilize the rumen pH and that levels up to 10 g/kg diet could be utilized to improve fungi count.
