Abstract EN

The present study was conducted at Sheep and Goat Research Station/ Al-Shatra/ Dhi-Qar Agriculture Directorate/ Ministry of Agriculture.

The study was done during the period 25/5/2016 to 25/8/2016.

The aim was to study the effect of giving different levels of Yeast daily to Arabi lambs to enhancethe intake of baggas and itseffect on lambs performance.

A total of 17 Arabi male lambs aged 3 – 4 months with an average weight of 20.54 ± 2.57 kg.

the lambs were distributed randomly in to three feeding groups.

The first group (5 lambs) fed a control ration , consist of 20% wheat powder , 25% wheat bran , 25% barely , 20% crushed corn , 7% soya bean meal and 3% vitamin and minerals.

As well as baggas treated with urea and molasses ad libtium.

Lambs was fed a concentrate as 2% of their live body weight.

The second group (6 lambs) fed a control ration with 3 gm yeast/animal/day.

The third group (6 lambs) fed a control ration with 5 gm yeast/ animal/day.

The results showed that RBC and Hb did not significantly differ due different groups.

However, PCV revealed a significant (p˂0.05) differences among treated groups.

A group of lambs received 3 gm yeast/head/day highest value in comparison with control and 5 gm yeast/head/day (22.18, 17.62 and 18.82 respectively).

There was no significant differences in WBC, while differential counts showed significant differences in lymph cell (71.54, 67.82 and 67.66%) for groups of 3 gm yeast/head/day, 5 gm yeast/head/day and control groups.

All studied biochemical parameters significantly decreased due to treatments except globulin significantly increased.
