Feeds And Feeding Of Sheep And Goat

Comparisons were made between 24 Ethiopian rams and 24 Galla goats for voluntary intake, feed selectivity and growth performance when offered three levels of sorghum stover. The levels observed were 25,50 and 75 g/kg live weight per day. Measurements of intake, growth and feed selectivity were taken over a period of 10 weeks.
Both sheep and goats consumed more stover (P<0.001) as rate of offer was increased (22, 31, 32 gDM/kg live weight per day; 19,26,29 g/kg live weight per day, respectively, for sheep and goats). Increasing the level of offer beyond 50g/kg live weight per day did not, however, promote a substantial increase in intake. No difference (P>0.05) was observed in the pattern of feed selectivity between sheep and goats. Both species showed a similar preference for leaf and sheath matter as the level of offer was increased.Sheep gained weight faster (P<0.001) than goats at all rates of offer, (28.0 vs 9.0; 54.0 vs 23.0; 62.0 vs 31.6 in favour of sheep). Those on a higher level of offer showed a faster rate of gain than those on a lower level of offer.
It was concluded that both species can benefit from generous offers and that the benefit, judged by improved intake and growth, is due to selective feeding.

CHAPTER ONE - [ Total Page(s): 2 ]No performance comparison has been made between sheep
and goats that have been fed untreated crop residues at levels that
would allow selective intake. Alimon (1989) only measured the digestible
organic matter (OM) intake of goats offered increasing levels of feed,
but did not measure any related growth performance. Aboud et al (1993)
showed that certain levels of offer encouraged sheep to eat selectively.
By offering goats and sheep the same type of sorghum stover at these
levels ... Continue reading---
