| Abstract |
Thirty Baladi lambs of average 25 ± 0.20 Kg body weight were randomly divided into five groups and assigned to the following feeding treatments:
1-Chopped wheat straw (ad lib) and concentrate feed mix (CFM) at 2.5%
of LBW (control group)
2- Chopped ureated WS (ad lib) and concentrate feed mix (CFM) at 2%
of LBW
3- Berseem hay (ad lib) and concentrate feed mix (CFM) at 1.5% of LBW 4- Chopped ureated WS (ad lib) and concentrate feed mix (CFM) at 1.5% of LBW and Block (ad lib)
5- Chopped ureated WS (ad lib) and concentrate feed mix (CFM) at 1.5% of LBW and 100 ml of EI-Mufeed liquid/h/d A comparative feeding trial for 18 weeks was conducted during summer. Five metabolism trials were carried out in order to evaluate the feeding value of the experimental rations.
The results obtained were as follows:
1- Berseem hay ration (group 3) had better digestion coefficients, feeding value, nitrogen balance, daily gain and feed conversion than other groups.
2- EI-Mufeed ration (group 5) recorded the lowest feed cost per Kg weight gain and the best economic efficiency. Lambs fed urea molasses block ration (group 4) was better in feed conversion (as Kg TDN/Kg gain)
3- Results indicated that no significant differences among groups in rumen liquor parameters (pH, TVFA's and ammonia). Block ration (group 4) resulted in higher pH and ammonia and lower TVFA concentrations.
4- Berseem hay ration (group 3) resulted in increased plasma TP and albumin, while EI-Mufeed ration (group 5) resulted in increased in increased plasma glucose.
It is concluded that the nutritive value of roughage can be improved by chopping to 3cm or ureation. Premixes such as EI-Mufeed or urea molasses blocks can be used to reduce the cost of nutrition.
