  • Abstract:

A fifty-six day feeding trial was conducted to assess the nutritive value of rumen digesta and poultry droppings mixed meals in West African Dwarf (WAD) Sheep’s diets.

Four diets were formulated such that sun-dried rumen digesta (SRD) having a crude protein content value of 13.87% was not included in control diet (A) but incorporated in diet B, while sun-dried rumen digesta-poultry droppings (SRDPD) and fermented rumen digesta-poultry droppings (FRDPD) mixed meals were included in diets C and D, at 25% inclusion level, respectively. The diets were fed to sixteen (16) West African Dwarf sheep at four sheep per dietary treatment.

The dry matter intake (DMI) significantly (P<0.5) increased with inclusion of SRD, SRDPD and FRDPD in the diets, the DMI values varied from 78.98g/kgW0.75 (diet A) to 85.09g/kgW0.75 (diet D). Digestibility of dry matter, fibre fractions and other nutrients varied (P<0.05) significantly, the digestibility value of crude fibre increased with inclusion of rumen digesta and poultry droppings in the diets from 30.78% (diet A) to 43.96% (diet C) and decreased to 21.03% (FRDPD). This observation implied that the inclusion of the dietary rumen digesta and poultry droppings enhanced the dietary intake and digestion of the diets.   . The weight gain differences were not significant (P>0.05) but the values varied from 31.61g/kgW0.75/day (SRDPD) to 33.57g/kgW0.75/day (FRDPD). The feed conversion ratio was not influenced by the inclusion of SRD, SRDPD and FRDPD but the diet D (FRDPD) produced animals with highest feed intake and weight gain.  The positive nitrogen retention values reported in this study were influenced significantly (P<0.05) and decreased with the dietary inclusion of SRDPD and FRDPD. However, the result showed that all diets, with or without dietary inclusion of rumen digesta and poultry droppings could satisfy the dietary protein requirements of the animals due to high crude protein contents of the diets because the animals did not showed signs of ill health.  Therefore, the inclusion of fermented  rumen digesta (abattoir waste) and poultry droppings mixed meal (FRDPD) in sheep or goats formulated diets would be a valuable source of protein and energy supplement and purposeful outlet for the wastes which could reduce environmental pollution.
