This study was carried out to investigate the effect of pomegranate dried waste (PDW) supplementation as natural antioxidant source on some reproductive and productive traits and blood constituents' doe rabbits, during summer season in Egypt. Twenty eight of New Zealand White (NZW) does aged 6 months with an average weight of 2942.5 ± 48.14 g were used from April and lasted 16 weeks with 7 does per treatment groups and allotted into four dietary groups. First group was served as control, while, 2 nd , 3 rd , 4 th groups were fed control diet with levels 0.5, 1.0 and 1.5% PDW, respectively. Results indicate that PDW levels at 0.5, 1.0 and 1.5 with a few exceptions were ranked first, second and third as had the highest values for feed intake during pregnancy (P<0.01), and lactation periods (P<0.05), litter size at birth (P<0.01) and weaning (P<0.05), litter weight at weaning (P<0.05), milk production (P<0.01) through 4 weeks of lactation, while it was lowest values of and pre weaning mortality rate (P<0.0001) during birth to weaning age. Doe rabbits receiving 0.5, 1.0 or 1.5% levels of PDW had a significant decrease in blood triglyceride (TG), low density lipoprotein (LDL) and very low density lipoprotein (vLDL). The activities of different blood plasma enzymes were significantly enhanced. Interestingly, PDW levels increased both the blood plasma antioxidant enzymes (TAC, SOD and GPx). These results may indicate that dietary supplementation of PDW could be used up to 1.0 % to have a favorable effect in the improvement of doe rabbits performance and antioxidant status during summer season in Egypt.

This study was conducted to evaluate the effects of some herbal extracts on growth performance and blood parameters of growing New Zealand White (NZW) rabbits under Upper Egypt conditions of the summer season. Seventy two weaned rabbits At 5 week 's age (743.17±12.4 g body weight) were randomly divided into 6 groups. Control group, rabbits received water without additives. In C1 and C2 groups, rabbits received chamomile aqueous extract at 5 and 10 ml/L of drinking water, respectively. In R1 and R2 groups, rabbits received rosemary aqueous extract at 5 and 10 ml/L of drinking water, respectively. The last group (CR) rabbits received a mixture from chamomile and rosemary aqueous extract 5 /L water. During the experimental period the body weight, average daily gain, feed intake (FI), feed conversion ratio (FC) and some blood parameters were estimated. Also, the mortality rate was calculated. The result revealed that the supplement a combination of chamomile and rosemary (CR) increased (P< 0.05) average body weight gain and daily gain as compared C1, R1 and R2 groups. The feed intakes did not affected between the treated groups and control one. However, the feed conversion ratio was significant improved (P<0.01) of rabbits drinking water contains a mixture of chamomile and rosemary extracts (CR) when compared with rosemary groups (R1and R2). The Serum total protein (TP), albumin, glucose, total cholesterol and triglyceride concentrations were significantly lower (P<0.05) in all treated groups than control group. Supplementing chamomile at levels 5ml and 10ml/L to drink water of rabbits decreased the concentration of serum urea and creatinine when compared with control group. Supplement rosemary extract at 10 ml/L to drinking water of growing rabbits increased (P˂0.05) the number of WBCs as compared with control group (7.07 vs. 3.65 x10 3 , respectively).

The present study aimed to investigate the effects of different levels of dietary supplementation of rocket (Eruca Sativa) seeds, carrot (Daucus Carota L) seeds or bay laurel (Bay laurel Nobilis L)., leaves and their mixed between them on some reproductive and productive traits, antioxidant status of doe rabbits and their offspring's, during the pregnancy and lactation periods, under the same conditions.Forty eight New Zealand White (NZW) doe rabbits about 6-7 months old (2.890-3.070 kg) were randomly allotted to eight dietary groups (6 rabbits in each treatment group). The first group was fed a basal diet as control group,(T1); while the experimental second to eighth groups were fed the basal diet supplemented with 1.0% rocket seed (T2); 1.0% carrot seed (T3); 1.0% bay laurel leaf (T4); 0.5% rocket seed+0.5% carrot seed (T5); 0.5% carrot seed+0.5% bay laurel leaf (T6); 0.5% rocket seed+0.50% bay laurel leaf (T7) and 0.33% rocket seed+0.33% carrot seed+0.33% bay laurel leaf (T8), respectively. The experimental period lasted for 16 weeks. Live body weights of does before and after parturition days and at first day of lactation were significantly higher (P=0.05, 0.002 and 0.01) in all treated rabbits as compared to control group respectively, while the response of does live body weights at weaning day was not significant. All treated groups had significantly higher total feed intake during pregnancy and lactation when compared to the control group. During pregnancy constantly plasma, antioxidant capacity and endogenous antioxidant enzymes in terms of glutathione peroxidase (GPx) and superoxide dismutase (SOD) were higher in treated groups compared to the control group, however the effect was significant in some treated groups. Hence, lipid peroxidation in terms of TBARs was significantly reduced in all treated groups 464 BASYONY & AZOZ compared to control. Metabolic and sex hormones (T3 and E2) were significantly leveled up in all treated groups, while the effect on progesterone (P4) hormone was significantly higher for some treatments. During lactation period weekly and total milk yield were higher in treated groups. The improvement of milk yield was significant increased in T3, T4, T7 and T8 compared to the control group. During lactation period data on plasma antioxidant, constituents and hormones followed the same trends as in these concerning pregnancy periods, where treated groups surpassed the control group and favored the parameters evaluated. Litter size and weight at weaning significantly (P=0.01 and 0.004) increased for all feed additives compared to control, respectively. The same trends were observed in litters weight gain fed diets supplemented with different feed additives. Means of pre-weaning survival rate (%) from birth to weaning age in the treatments groups were better significantly than control group. Conclusively, the findings of this study demonstrated that dietary supplementation of feed additives rocket seeds and carrot seeds or Bay leaves individually or in combinations improved reproducti...

A factorial design was conducted to evaluate the effect of live dried yeast (Saccharomyces cerevisiae) (SC) and sodium butyrate (SB) on growth and physiological performance of growing New Zealand White)NZW(rabbits. Sixty weaned rabbits were specified indiscriminate into six equal groups were fed for eight weeks. All trail groups were fed a uniform rabbit's pelleted diet, (1) basal diet control, (2) basal diet plus 0.3 g sodium butyrate (SB), (3) basal diet plus 0.5g SB, (4) basal diet plus 0.1% Saccharomyces cerevisiae (SC), (5) basal diet plus 0.1g SC plus 0.3g SB and (6) basal diet plus 0.1g SC plus 0.5g SB. Data of growth performance, pH, ammonia-N (NH 3-N) and volatile fatty acid (VFA) production of cecal content, digestibility and nutritive value, nitrogen balance and blood biochemical were analyzed in 2×3 factorial design. The results revealed that feed additives as SC and SB used alone improved significantly body weight (BW) and body weight gain (BWG) as compared to the control group. Addition the basal diet with 0.1 SC revealed (P<0.05) improved in feed conversion ratio (FCR). Cecum pH did not (P>0.05) effect by SC and SB or their mix supplementation. Using mixture of SC and SB or alone gave a positive results on the volatile fatty acids (VFA) concentration vs control group. The opposite trend was noted in NH3-N concentration, which was (P<0.05) decreased related to control one. Rabbits fed diets containing 0.1 SC caused (P<0.05) to improve in dry matter (DM), organic matter (OM), crude protein (CP), crude fiber (CF) and Nitrogen free extract) NFE (digestibility and nutritive value of DCP. Growing rabbits fed SB at 0.3 and 0.5g / Kg diet (P<0.05) increased the CP digestibility, nutritive value of DCP. Addition SC in rabbits diets initiated observable increased (P<0.01) in serum total protein (TP) and Glob vs control. Also, lipid profile as Cholesterol (CHO), TG low and High density lipoprotein (HDL) was decrease (P<0.01) vs control. Also, 0.5g SB
