“…In addition, eye muscle area was significantly higher in G2 and G3 than in G1 and G4, attaining 27.84 and 26.98 cm 2 vs. 25.21 and 24.62 cm 2 , respectively). These results are in agreement with those reported by Almitairy et al (2011).…”

“…The observed improvements in ADG of calves in G2 and G3 might be due to higher intake of TDN and DCP from these rations (Table 4). These results were in line with that mentioned by Almitairy et al (2011) and El-Hag et al (1993) and El-Gasim et al (1986), who concluded that adding DD in diets increased weight gain of Awassi lambs. Also, Hassan et al (2013) reported the highest ADG in lambs fed diet containing 10% DD.…”

“…In lambs, Mohammady et al (2013) found also that lean meat percentagewas higher in lambs fed DD-diet than those in control. On the other hand, Almitairy et al (2011) indicated that the eye muscle area did not reflect significant differences of lambs fed DD-diets as compared to control.…”

“…In addition, El-Shora et al (2014) found that cows fed 66% DD showed higher ADFI than the control and 100% DD groups. Almitairy et al (2011) showed that ADFI was significantly (P<0.05) higher for male lambs fed 30% than 0 or 15% DD-diets, in replacing the commercial concentrate mixture. In goats, Abd El-Rahman et al (2012) reported that the DM intake of rations supplemented with high DD was higher than that of other tested rations.…”

Aim of the present study was to evaluate the effect of replacing yellow corn with different levels of discarded dates in concentrate feed mixture on, feed intake, growth performance, feed conversion, carcass characteristics and economic feed efficiency of fattening Friesian calves. Twenty male Friesian calves (241.20±2.14 kg and 11 mo of age) were randomly assigned into four groups (five in each). Discarded dates (DD) was used in partial replacement of yellow corn grains (YCG) (w/w) in concentrate feed mixture at levels of 0% (G1), 33% (G2), 66% (G3) and 100% (G4), respectively. Results showed that DD contained higher CF, ash, lucien, isolucien, lysine, methionine, cysteine and histidine contents and lower OM, CP and NFE contents compared with YCG. All DD-diets slightly increased feed intake up to 66% DD. Final body weight, total and daily weight gain, and relative weight gain were higher (P<0.05) in G2 and G3 than in G4 and G1. Feed conversion improved (P<0.05) with increasing DD level up to 66% in G2 and G3. Average weights of pre-slaughtered animals, hot carcass, and boneless meat were higher (P<0.05), while weight and percentage of bone decreased (P<0.05) in G2 and G3 as compared to G1 and G4. The highest percentages of dressing and boneless meat was in G2, followed by G3, while G1 and G4 showed the lowest (P<0.05) percentages. Rib cut weight was higher in G3 and G2 than in G1 and G4. Percentage of lean, fat and bone was higher in G2, followed by G3, G4 and G1, respectively. Economic feed efficiency was higher for calves in G2, G3 and G4 by 19.44, 30.56 and 21.53% compared with those in G1 (control group), respectively. The current study concluded that dietary incorporation of discarded dates up to a level of 66% instead of yellow corn had impact on growth performance, carcass traits and economic feed efficiency of fattening calves. In addition, using discarded dates as by-products in ruminant diets could be useful in reducing the environmental pollution in Egypt.

“…Many animal herd owners in different countries that producing dates are using discarded dates as a supplement to their animals feed. It is the high time to use local unconventional sources of feed to fill the gap between demand and supply of the limited feed resources and to substitute the conventional high priced imported sources (Almitairy et al, 2011).…”

Twenty lactating Friesian cows with average live body weight of 550 ±18 kg in their the 2 nd to 5 th parity were used to study the effect of replacing yellow corn grains (YCG) by discarded dates (DD) in concentrate feed mixture (CFM) at levels of 0, 33, 66, and 100% (w/w), on their productive and reproductive performance. Cows were assigned randomly to four similar groups (5 in each) according to milk yield, parity and live body weight (LBW). The levels of replacement of YCG by DD in CFM were0, 33, 66, and 100% (w/w) for G1 (control), G2, G3 and G4 as tested rations, respectively.Results showed that the contents of OM, CP and NFE were higher in YCGcompared to DD-ration, however the content of CF and ash showed an opposite trend. Cows in G3 (66% DD) recorded the highest (P<0.05) digestibility coefficients of all nutrients, nutritive values and the intake of DM, TDN and DCP, followed by G2 and G4, while G1 (control) almost had the lowest values. The pH value in rumen liquor markedly decreased after feeding and its values 3 h after feeding were lower (P<0.05) with the DD-rations than control. The highest TVFA's concentration in rumen liquor was recorded with in G3 after feeding, while the lowest concentration was found in G1 after feeding. Ammonia-nitrogen concentration in G3 was higher before and after feeding than the other treatments. Cows in G3 had the highest concentrations of total proteins, globulin and glucose and the lowest concentrations of albumin and total lipids in blood plasma. Yield as actual milk and 4% FCM were higher (P<0.05) for DDrations than those of control, being the highest in G3. Cows in G3 recorded the highest (P<0.05) percentages of fat, protein, and total solids in milk. Cows in G3 showed the best feed efficiency (DM, TDN and DCP: 4% FCM) compared with those fed the other rations (P<0.05). Average daily feed cost was higher (P<0.05)in G2 and G3 as compared to G1 and G4. While, cows in G3 showed the lowest feed cost/ kg 4% FCM and the best economic efficiency followed by G4 and G2, while G1 had the opposite trends. Cows in G3 had the best of most reproductive traits as first estrus, first service, service period, number of service /conception and conception rate. It could be concluded that partial replacement of yellow corn grains by discarded dates at the level of 66% as a source of energy in concentrate feed mixture improved the feed intake, digestibility, rumen fermentation activity, yield and composition of milk, economic feed efficiency as well as the post-partum reproductive traits in Friesian cows.
