To investigate the effect of feeding growing lambs on dried sugar beet pulp (DSBP) or/and dried sugar beet tops (DSBT) as replacement of concentrate feed mixture (CFN) or/and berseem hay (BH) on characteristics of puberty, testosterone profile, scrotal circumference and physical semen characteristics of ram lambs, 24 ram lambs (3/4 Romanof x % Rahmani) aged 5 mo with 23.46 kg average body weight were divided into four groups, 6 animals in each. Ram lambs in the 1st group (G1) were fed on ration composed of 50% CFM+50% BH (control ration). Ration of the 2nd, 3rd and 4th groups were as the following: G2: 25% CFM+25% DSBP+50% BH; G3: 25% CFM+25% DSBP+37.5% BH+12.5% DSBT and G4: 25% CFM+25% DSBP+25% BH+25% DSBT. Results show that the dietary treatment had no significant effects on puberty characteristics of ram lambs including age, body weight, scrotal circumference and testosterone concentration at different puberty stages (first mounting, mounting accompanied with erection and mounting accompanied with erection and ejaculation of 1st sperm. The group differences in physical semen characteristics of the 1st ejaculate at puberty including ejaculate volume (EV), percentage of initial motility (IM) and abnormal sperm (AS), sperm cell concentration (SCC), and output of live sperm (LS) and live normal sperm (LNS) were not significant. Only LS percentage in G3 decreased (P<0.05) as compared to G1 (control). Ram lambs in G4 fed mixed of 25% DSBP+25% DSBT showed higher (P<0.05) testosterone concentration and lower scrotal circumference than in G1. During the collection period of semen, EV and percentages of IM and AS were not affected significantly by dietary treatment. However, inclusion of 25% DSBP (G2) in diet of ram lambs decreased (P<0.05) percentage of LS and inclusion of 25% DSBP 25% DSBT (G4) increased (P<0.05) SCC/ejaculate and LNS output as compared to the control and other treatment groups. Output of TS increased (P<0.05) in G4 than in G2 and G3, but did not differ from that in the control group (G1). It could be concluded that inclusion of 25% dried sugar beet tops and 25% dried sugar beet pulp could be used successfully as a replacement of 25% of berseem hay; and 25% of concentrate feed mixture in diet of ram lambs.

Aim of this study was to evaluate the effect of treatment with vitamins A (VA), C (VC) and AD3E, selenium (Se) or their combination before September mating season, on productive and reproductive performances of crossbred ewes and their offsprings. Total of 72 crossbred ewes (3-4 y of age and 44.19 kg live body weight, LBW) were used in this study. Ewes in the 1st group (G1) served as a control without treatmant, while those in treatment groups were treated orally with VA (5000 IU/ewe, G2) or injected with 1 ml of AD3E (G3), Se (G4) or VC (G5), or with the same treatments of their combination (G6). LBW of ewes and lambs as well as placental weight (PW) were recorded. Milk yield was individually recorded and milk samples were taken for chemical analysis during 45 d of the suckling period. Blood samples were collected for determination of progesterone (P4) concentration during 50 post-mating in ewe serum, and of concentration of total proteins (TP), albumin (AL), globulin (GL) and cholesterol in lamb serum at weaning. Reproductive indexes including estrus rate (ER), fertility rate (FR), fecundity rate (FCR) and prolificacy rate (PR) were also calculated. Mortality rate (MR) of lambs was recorded at weaning.
Results show that the effect of treatment on LBW of ewes, PW of ewes or LBW of lambs at birth or weaning based on sex of lambs and type of birth, milk yield, milk contents, except fat percent, P4 concentration, and average LBW of lambs at lambing or weaning based on sex and type of birth was not significant. Average PW of all lambs was lower (P<0.05) in G3 and G2 than in G1, G4, G5 and G6. Milk fat percent increased (P<0.05) in G2 and G3 (5.04 and 5.43%), while it did not differ in G4, G5 and G6 (4.28, 4.62 and 4.29%) compared with G1 (4.47%). ER was 0.0, 25, 33.3, 16.7, 25 and 16.7% (P<0.05) during the transit period and 100, 83.4, 91.6, 100, 100 and 100% (P<0.05) at the end of breeding season in the treatment groups, respectively. FR was 83.3, 91.7, 75.0, 75.0, 91.7 and 91.7% (P<0.05), FCR was 125, 133, 100, 92, 108 and 108%, and PR was 150, 145, 133, 122, 118 and 118% in the six groups, respectively. Ewes in G2 showed the highest (P<0.05) twin births and the lowest single type (62.5:37.5%, P<0.05) versus an opposite trend in other treatment groups (G3-G6). MR of lambs at weaning was 0% in G1, G2 and G6 versus 8.33, 9.10 and 7.69% in G3, G4 and G5, respectively. Lambs of G6 showed the highest (P<0.05) concentration of TP, AL, GL and cholesterol.
In conclusion, The treatment with vitamins A (VA), C (VC) and AD3E, selenium (Se) or their combination before September mating season improvement the productive and reproductive performances of crossbred ewes and their offsprings.

Twelve adult Rahmany rams 62.4kg of body weight and 3 years of age were used in this study , with aimed to overcome oxalic acid in sugar beet vein silage and to estimating the effects of oxalic acid residual on rumen microorganisms activities. The animals were randomly divided into four groups , assigned to four digestion trials. The experimental rations were50%concentrate feed mixture(CFM)+50% roughage as berseem hay for control or one of sugar beet top silages either, untreated (USBS),chemical treated(CSBS) or biochemical(B-CSBS), for second , third and fourth rations respectively .Trials were conducted and lasted for 22 days .The results of chemical composition for tested ingredients and calculated chemical composition of the consumed rations fed by adult Rahmany rams reveals’ that the B-CSBS was higher of CP and NFE, while the CF and Ash had lower values when compared with control and USBS groups, however the means of cell wall constituents of experimental diets indicated that the B-CSBS silage had the lowest contents of neutral detergent fiber (NDF),acid detergent fiber(ADF),acid detergent lignin(ADL),hemicelluloses and cellulose. on the other side ,the data of oxalic acid was clearly that the chemical and biochemical sugar beet tops silages were lower of oxalic acid than those of untreated sugar beet tops .The digestibility of B-CSBS was higher in OM ,CP, EE and NFE compared with CSBS, USBS and control diet . At the same time the USBS was significantly higher (p<0.05) for NDF, ADF, ADL, cellulose and Hemicellulose than other tested groups. while feed intake of USBS was significantly (P<0.05)higher compared with other groups and the values were ranged between 2316-2952g / h /d dry matter. Ruminal TVFA were significant higher (p<0.05) of acetic, butrtate and iso-biotrate for USBS group compared with the other tested groups, whereas propionate and valerate were significantly lower (p<0.05) for the same treatments in this respect .The highest values of total celluolytic bacterial, total bacterial and total protozoal count were obtained at 3 hrs post feeding of USBS was significantly (P<0.05) lower. While the rumen nitrogen in both of chemical and biochemical treated sugar beet top silage caused increase of NPN in rumen, however, total nitrogen of B-CSBS was significantly(P<0.05)higher at 3 and 6 hrs post feeding compared with other experimental groups..

A total of 30 New Zealand White (NZW) doe rabbits 9~12 months old and weight 2.74±0.23 kg was divided in to three equal groups, according to their weights and age, ten animals in each. Rabbits of 1st group (G1) were fed commercial rabbit diet (control group). Rabbits of the 2nd group were received a dose of ascorbic acid (AA) 25 mg/rabbit/day in drinking water one week before service (G2) until the weaning age of bunnies while, those of the 3rd group (G3) were received a dose of ascorbic acid 50 mg/rabbit/day in drinking water one week before service until the age of weaning of bunnies. All rabbits were given diets to meet NRC (1977) requirements of doe rabbits for pregnancy and suckling. Results revealed that total dry matter intake (DMI), TDN and DCP were significantly (P<0.05) higher for G2 and G3 than those of control group. Digestibility coefficients of DM, CF and EE were significantly higher (P<0.05) by supplementation of ascorbic acid than in control group. Concentrations of total protein and globulin were significantly higher (P<0.05) in G3 and G2 than in G1. Urea-N concentration was lower (P<0.05) in G3 and G2 than in G1. Average daily milk yield (ADMY) of does was significantly (P<0.01) higher in G3 at 10 and 20 days of suckling. Fat percentage was significantly higher in does received ascorbic acid than the control group. However, lactose content was significantly (P<0.05) decreased in G3 compared to G2 and G1. Litter size at birth and weaning was significantly (P<0.05) higher in G3 than in G2 and G1. Litter weight at weaning was significantly higher in treated groups than the control group. Mortalityrate during the suckling period was the highest in G1 than those in G2 and G3.
