Abstract

The Metabolizable energy and digestibility estimates
of mixed rations containing crop by-products as feeds for small ruminants was
investigated using the in vitro gas
production technique. Four concentrate feed mixtures of maize (TM), Cassava
peel (TCP), Plantain peel (TPP) and Yam peel (TYP) in a roughage base of Panicum maximum in the ratio of 40%: 60%
was formulated as potential readily available diets for small ruminants.
Results reveal that the TCP supplemented energy based diets possess a higher ME
value than the ME values for the plantain peel TPP, TM and TYP supplemented
diets. The ME values recorded for TCP and TPP were within the recommended ME
values for an average diet (6 – 13 MJ/kg/DM); hence can fulfill the energy
requirements for small ruminants when utilized. Similarly, the TYP and TPP
treatment groups recorded the highest value of SCFAs, hence being a major
source of energy as well as a building block for milk synthesis. The diet
containing TCP recorded the highest organic matter digestibility (OMD) after 24
hours of incubation. It is therefore recommended that non-conventional
feedstuffs such as crop by-products could be better substitutes as energy
sources in sheep and goat diets on account of their nutritional value in terms
of metabolizable energy (ME), short chain fatty acids (SCFAs) and organic
matter digestibility (OMD) as well as their ready availability and
predominance, cheapness and better economic gains to small ruminant farmers.

 

 Key words: Metabolizable
energy, digestibility, in vitro gas
production, crop by-products, small ruminants, diets.
