Productive Performance of Lactating Buffaloes Fed Rations Containing Sugar Beet Tops and Corn Silages

Abstract

Sixteen multiparous lactating buffaloes in 2 nd and 5 th lactating season and weighing 500 to 600 kg were used after 8 weeks of calving in complete switchback design with four groups. Buffaloes in the first group were fed the control ration (R1) containing 60 % concentrate feed mixture (CFM) + 20 % rice straw (RS) + 20 % berseem hay (BH) on DM basis, while in the other groups buffaloes were fed rations consisted on DM basis of 40 % CFM + 20 % RS + 40 % sugar beet tops silage (SBTS) and corn silage (CS) in different ratios, 2:1 (R2), 1:1 (R3) and 1:2 (R4) on DM basis, respectively. Results showed that the contents of CP and ash increased with increasing the proportion of SBTS, but OM, CF and NFE contents increased with increasing the proportion of CS in the rations. Digestibility coefficients of DM, OM, CF, EE and NFE, TDN and feed intake as DM and TDN increased (P<0.05) with increasing CS level, however, CP digestibility, DCP value and CP and DCP intake increased (P<0.05) with increasing SBTS level. The pH value and NH3-N concentration increased (P<0.05) with increasing SBTS level of, however TVFA's concentration in rumen liquor (RL) increased (P<0.05) with increasing CS level. Buffaloes fed R3 recorded (P<0.05) the highest milk and 7% FCM yield, however, those fed R1 had the lowest yield. The percentages of fat, lactose and total solids (TS) in milk increased (P<0.05) with increasing CS level, however, the percentages of protein, solids not fat (SNF) and ash increased (P<0.05) with increasing SBTS level. Animals fed R3 showed the lowest amounts of DM and TDN required per kg 7% FCM while R4 showed the lowest amounts of CP and DCP required per kg 7% FCM. however, those fed R1 revealed the highest amounts (P<0.05). Buffaloes fed R3 showed the lowest feed cost/kg 7% FCM and the highest price of 7% FCM and economic efficiency, but those fed R1 had on opposite trend (P<0.05).

Some Nutrition Studies on Using Ureated Sugar Beat Leaves and its Effects on Sheep Performance

“…The increase of total protein concentration in blood plasma by increasing ureated sugar beet leaves. (T2 and T3) compared with T1 may be related to the enhancement in metabolic process particularly digestible crude protein and nutritive value (Table 2) and higher energy intake for ureated SBLS, than control group consequently the higher microbial protein mas which raised ruminant TPN concentration, which leads to more absorbed amino acids by papilla's in small intestine to blood stream (Mansour and Al-Zahar, 2018) and (Bendary et al, 2000). Albumin (AL), Globulin (Gb) and urea (Ur) concentrations were mat (Table 6) significant (P>0.05) difference were detected among treatments, the figures, were 4.07 & 4.07 vs 3.5 g/dL for AL, trait, 3.73& 4.03 vs 3.23 g/dL respectively for Gb trait while urea were 38.33 & 39.00 38.67 g/dL res.…”

Effect of Replacing Berseem Hay by Dried Sugar Beet Tops on Performance of Friesian Calves

“…They found that the nutritive value expressed as TDN and DCP for R3 (100% DSBT) was significantly lower (P<0.05) than for R1 (0% DSBT) and R2 (50% DSBT) but there is no significant differences between R1 and R2 were observed. Gaafar et al (2011) reported that the TDN and DCP values increased (P<0.05) with increasing the level of sugar beet tops silage in the rations when feeding lactating buffaloes after 8 weeks of calving.…”

“…However, the apparent digestibility of DM and CP were not significantly higher between G1 and G4, but the lowest value reported with G5. Gaafar et al (2011) and Bahira, Mohamed (2002) who found that the percentages of total digestible nutrients TDN and digestible crude protein DCP were improved by feeding on rations containing different forms of sugar beet tops.…”
