A total of 216 day old broiler chicks (Arbor Acers) were weighed and distributed into equal 4 experimental groups of three replicates for each to explore the effect of dietary grape seeds (0, 0.5, 1.0 and 1.5%) addition on growth parameters, nutrients utilization and carcass characteristics as well as economic efficiency during fattening period (1-35 days of age). The results indicated that live body weight, body weight gain , feed conversion ratio and production index traits significantly (P≤0.05) improved for chicks fed diet contained 1.0% grape seeds (GS), while these parameters recorded non-significant improvement by 0.50 and 1.5%GS levels compared with chicks fed the control diet during the entire experimental period (0-35 days of age). Using GS in broilers diet recorded non-significant improvement for nutrients digestibility than the control except for fiber digestibility which was significantly improved. Feeding value improved (P>0.05) for chicks by dietary grape seeds addition. Total edible parts (%) insignificantly elevated by feeding different GS diets than the control. Chicks fed 1.0% GS diet recorded the best economic efficiency compared with the control at the entire experimental period. Therefore, it might be concluded that feeding diet contained 1.00% GS for broiler chicks might be used to improve growth performance and nutrients utilization as well as economic efficiency during the fattening period.

The current work was done to study the impact of supplementation Spirulina platensis alage into the rations of growing Friesian calves on feed intake, rumen fermentation activity, digestibility, growth performance and economic efficiency. Eighteen Friesian calves aged 12 months with initial live body weight of 219.06 ± 5.35 kg were divided into three groups for 150 days feeding trial. Calves were individually fed a basal ration composed of 50% concentrate feed mixture (CFM) + 30% corn silage (CS) + 20% rice straw (RS) on dry matter basis without supplementation (control, R1) or with 1 g (R2) and 2 g (R3) dry Spirulina alage/ head/ day. Results showed that calves fed R3 recorded significantly (P<0.05) the highest nutrients digestibility and feeding values compared with R2 and the control one (R1). Intake of total dry matter (DM), digestible crude protein (DCP) and total digestible nutrients (TDN) were nearly similar for the different groups. The concentration TVFA’s was significantly higher, while pH values and NH3-N concentration were significantly lower (P<0.05) in rumen liquor with the two Spirulina rations compared with the control one. Total protein concentration in plasma increased significantly (P<0.05) with Spirulina rations compared with the control one, while the rest of blood metabolities did not affected by the dietary treatments. Final live body weight, total and daily weight gain, as well as the improvement of daily gains were significantly higher (P<0.05) for the high level of dry Spirulina compared with the low level of dry Spirulina and also the control one. Feed conversion as DM, TDN and DCP required for producing one kg weight gain were lower significantly (P<0.05) for calves with Spirulina rations compared with those of control. Average feeding cost was nearly similar for the different groups. Whereas, feed cost per one kg live weight gain was significantly lower (P<0.05) for the two Spirulina rations than that of the control one. As well as, total revenue of body weight gain and net revenue as well as economic efficiency were significantly higher (P<0.05) for calves fed Spirulina rations than those of control ration.
