Abstract:

This experiment was carried out to determine
the effect of coat pigmentation on feed and water intake of West Africa Dwarf Sheep
using 24 weaned lambs with different coat pigmentations. Feed intake of Panicum maximum and concentrate feed, water consumption, weight gain as
well as feed efficiency were measured. The analysis of variance showed that the
effect of coat pigmentation was significant (p< 0.05) on forage intake,
weight gain, feed efficiency and water consumption. However, concentrate feed
intake was not significantly (p>0.05) affected by coat pigmentation. The
least value of weight gain was recorded for black sheep with the weekly gain of
0.49 ± 0.19kg. There was no significant difference in the weekly weight gain of
brown sheep and white sheep with 0.69 ±0.12kg and 0.60 ± 0.15kg respectively.
Brown coat pigmentation type had the highest feed efficiency of 0.25± 0.05
followed by white sheep (0.21 ±0.03) while the black sheep had the least feed
efficiency (0.18 ± 0.02). The mean daily
water consumption of the WAD sheep ranged from 0.96 ± 0.02 litre to 1.50 ±0.02
litre with the brown sheep having the highest water consumption while black
sheep had the least.  Female sheep
had lower feed efficiency and water
consumption than male sheep. In conclusion, animals with light pigmentation had higher values for feed
intake, daily water consumption and feed efficiency than the dark (black)
pigmentation.

Keywords: Coat pigmentation, feed intake, water
consumption, sheep.
