Using some fodder shrubs and industrial byproducts in different forms for feeding goats in Sinai [electronic resource].

Berseem hay (BH) and mixture of fodder shrubs (FS), which consisted of 30% Acacia saligna (AS) and Atriplex nummularia (AN) were chopped and ground to be used as roughage in desert goats rations. Eighteen mature male goats with an average live body weight of 32.91 :.0.414 kg were used in metabolism trials to assess the effect of FS and form of the ration on the digestibility. nitrogen balance and water balance and some rumen fermentation parameters. Animals were randomly assigned into sex feeding groups. R1 (BH+CFM) as mash, R2 {(BH) as mash + (CFM) as block}, R3 (BH + CFM) as block. R4 (FS+CFM) as mash, R5 {(FS) as mash + (CFM) as block} and R6 (FS + CFM) as biock. The experimentai rations contained 60 % CFM + 40 % roughage, the concentrate feed mixture (CFM) consisted of (23.5% date seed, 15% olive pulp, 25% wheat bran. 25% radicell, 10% molasses and 1.5% urea). The results showed a significant (P<0.05) difference in dry matter intake of CFM only between R1 and R6. the highest value of total dry matter intake was in R1 and the 10\'l3st value was in R5.Ration 1(R1) showed the highest digestion coefficients for all nutrients. The same trend was observed for the nutritive value as TON and DCP. There was a significant (P<0.05) difference in nitrogen balance among groups, the highest value was in R1, while the lowest value was in R5. Twenty four male goat kids (4 months old and 15.67 : 1.11 kg average live body weight) were used in a growth trial for 6 months. Animals were divided randomly into three feeding groups, R1 (BH + CFM) as mash, R3 (BH + CFM) as block and R6 (FS + CFM) as block. The same CFM and roughage: concentrate ratio, which were used in the diGestion trails were used in the growth trail. Average daily gains of animal R1 and R3 were significantly (P<0.05) higher than those in R6. On the other hand, animal in R6 had the highest economic efficiency than R1 and R3. From the previous data, it could be concluded that using feed blocks consisting of 60% CFM and 40% FS seems to be a good, practical and economical for feeding system for goats in the desert area.
