In the first experiment, twenty-seven mature NZW does and nine bucks with an average live body weight of 2.75-3.00 Kg and 5-6 months of age were divided into 3 experimental groups, with 3 replicates each, to study does productive and reproductive performance. Three experimental diets were formulated for does and bucks. Diet 1 (T1) served as the control and contained no Moringa oleifera leaf meal (0%). Diet 2 (T2) and Diet 3 (T3) contained Moringa oleifera leaf meal at the levels of 3% and 6%, respectively. In T2, the 3% MLM replaced 1% soybean meal and 2% barley. In T3, MLM at the level of 6% replaced 2.5% soybean meal and 4.5% barley. In the second experiment, the resulted bunnies of the used does in the first experiment (48 kids distributed to 4 replicates; 4 rabbits each) with an average weight of (800±20 g) were used in a fattening period lasted for 56 days starting after weaning (at 35 days age) and lasted till the 13th week of age. The growing rabbits continued to receive 3 and 6% MLM in their diets (T2 and T3) in a comparison to those received diets without MLM (T1) which served as the control. The second diet (T2) was contained 3% MLM substituted 2% yellow corn and 1% soybean meal. The third diet (T3) contained 6% MLM substituted 4% yellow corn and 2% soybean meal. Productive performance and carcass traits were measured. Economic efficiency of using these materials during the two experiments was considered as well. \u0000The obtained results showed that incorporating MLM in diets of mature NZW rabbits reduced significantly number of services for per conception (NSC), days open (DO) and kidding interval (KI). On the other hand, it had no significant effect on gestation period length (GPL) of does. Litter size (LS) significantly (P<0.05) increased with increasing MLM in the diets compared to the control diet. Litter weight (LW, g) followed the same trend of litter size with the superiority of high level of MLM in most cases. Mean bunny weight (MBW, g) significantly improved (P<0.05) with substituting MLM in the experimental rations.

Twenty five New Zealand White (NZW) does aged 5 months weighting 3140± 26.55g were randomly distributed into 5 experimental treatments (5 does/ treatment).

The study aimed to test three levels of linseed oil with soluble (1.5%, 3.0% and 4.5%) as feed supplementation to basal diet on some productive and reproductive performance of rabbit does. Some blood parameters as well as the economic efficiency of using these levels were also studied. \u0000 The obtained results show that 3.0% linseed oil supplementation significantly decreased (P≤0.05) the number of services per conception (NSC), days open (DO) and kidding interval (KI) without affecting the length of gestation period (GPL) compared to those of the control group. \u0000No significant effect on litter size (LS) as well as daily weight gain (DWG) from birth till 35 days of age due to different levels of linseed oil supplementation compared to those of the control group. While, supplementation with 4.5% linseed oil significantly improved (P≤0.05) litter weight (LW) and mean bunny weight (MBW) of NZW’ does. Although there were no significant differences among the experimental groups in mortality rate (MR%) during the first two periods (birth-21 and 21-35 days of age), the 3.0% linseed oil treatment gave the lowest (P≤0.05) MR%. \u0000Blood parameters showed that linseed oil supplementation groups had the highest (P≤0.05) total protein (TP) level recorded after the first parity followed by those recorded at the end of the experiment and after the second parity, respectively. The level of globulin (Glob.) was increased but without significant difference after the first parity and the albumin (Alb.) concentrations gave its high values in the 3.0% oil supplementation group. The highest total lipids (TL) obtained with 1.5% and 4.5% oil supplementation groups without significant differences between them, but such differences were significant with the other two experimental groups (control and 3.0% oil supplementation). The supplementation of diets with linseed oil generally tended to decrease cholesterol level compared to that of the control. The control group recorded the highest (P≤0.05) high density lipids (HDL) values compared to other groups of linseed oil supplementation which were insignificantly differed. Supplementing does’ diets with linseed oil resulted to significantly increase tri-glycerides (TG) (P≤0.05) especially after the first parity and at the end of the experiment. The 3.0% linseed oil supplementation recorded the lowest (P≤0.05) TG value among the other two supplemented groups at the end of the experiment. \u0000Conclusively, it could be concluded that supplementing diets of rabbit’ does with 3.0% linseed oil would impact positively on dams reproductive, productive traits and their health status. From economic point of view, the addition of oil as a source of Omega-3-polyunsaturated fatty acids decreased average feed consumed per parity by about 13% and improved relative economic efficiency by about 40%.","PeriodicalId":11684,"journal":{"name":"Egyptian Journal of Rabbit Science","volume":"169 1-4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83436584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
