A total of 75 weaned male New Zealand White (NZW) rabbits (5 weeks old) with an average initial body weight of (596.00±13.05 g) were randomly assigned to five experimental groups (15 rabbits for each). Five experimental diets were formulated; the first was used as a control diet (0% PPF and PPP). The other four diets were formulated to replace barley with either PPF or PPP at the levels of 25 and 50%. Results indicated that PPF and PPP are rich sources in vitamins C (2.4, 2.8μg/100g), vitamins E (25, 23μg/100g) and vitamin A (10, 13μg/100g). The content of gross energy (GE) in PPF was higher than that of PPP and barley. The obtained results revealed also that average of BW, BWG, FI and FCR were not affected (P<0.05) by feeding growing rabbits on diet containing either PPF or PPP under each tested level (25 and 50%) compared to rabbits group fed the control diet during (9-13) and (5-13) weeks old. Feeding growing rabbits on diets contained 50% PPF or 50% PPP resulted in noticeable improvement in both average BWG and FCR in comparison to the other experimental groups including the control group during the whole period (5-13 weeks old). Digestibility of OM, CP, EE and CF were not affected significantly by the inclusion of PPF (25 and 50%) or PPP (25 and 50%)compared to the control group. Besides, there were insignificant differences in TDN and DE among the control group and the other tested groups contained PPF or PPP under each tested level (25 or 50%). Rabbits fed a diet containing 25 and 50% PPP had the lowest (P<0.05) NH3-N concentrations while, rabbits fed 25% PPP supplemented diets had the highest (P<0.05) TVFA value. Rabbits fed diets containing 50% PPF or 50% PPP had heavier (P<0.05) liver, heart and edible giblets compared the control group while, rabbits fed diet containing 50% PPP showed the lowest (P<0.05) abdominal fat and the higher (P<0.05) values of serum antioxidant marker and enzymes (TAC, GSH-Px, SOD and CAT). Plasma triglycerides, cholesterol and LDL concentrations were decreased (P<0.05) while HDL concentration increased (P<0.05) in PPF and PPP supplemented groups compared to the control group. The inclusion of PPF or PPP in rabbit diets at a level of 25 or 50% improved economical efficiency and net revenue compared to the control group. Conclusively, according to the circumstances of this experiment, PPF or PPP could be incorporated in growing rabbit diets up to 50% as a partial replacement of barley, without any significant impairment of the growth performance and to achieve a better antioxidant status of rabbits and higher economic efficiency of diets.","PeriodicalId":11684,"journal":{"name":"Egyptian Journal of Rabbit Science","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75647531","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}

Rabbits aged 5-6 months and weighed 3098.15 ± 20.24 g on average. Plasma biochemical parameters were determined at 13, 21, 28 days of pregnancy and at kindling day. Also, the does weigh, litter size, litter weight, milk yield and milk compositions were determined. \u0000The results showed that,leptin levels increased slightly during gestation days, reached to the highest value (2.91 ng/ml) at day 28 of pregnancy and then declined at delivery day.  Furthermore, leptin levels positively correlated with GST and negativelywith H2O2and MDA. Both H2O2and MDA were at the lower levels day 28 of pregnancy when leptin recorded its highest level (2.91 ng/ml). This clear that, leptin may play an important role in the system of antioxidant and free radicals. Blood proteins (TP, Alb and A/G, except Glb) were associated positively with leptin levels. This indicates that, leptin may interfere with blood proteins metabolism. Furthermore, leptin correlated negatively with plasma TL, TG and Glu which declined during gestation days and recorded their lower values (154.47,135.11 and 106.55 mg/dl, respectively) at day 28 of pregnancy. Additionally, leptin also was in a negative relationship with BUN levels, which were higher than normal range at days 13 and 21 of pregnancy. Afterwards, significantly declined at day 28.Also, CR levels correlated negatively with leptin levels. The liver enzymes (AST and ALT) were in a negative relationship with leptin levels. These enzymes declined during gestation days recorded their lower values at day 28 of pregnancy, respectively. Also,body weight of dam, litter weights and size were positively associated with leptin levels, because leptin play an important role in regulating BW by controlling the mass of adipose tissue. Additionally, the results showed a negative relationship between leptin levels and milk yield, MF, ML and milk ash. In contrast, MP, MTS and MSNF were associated positively with leptin levels. \u0000In conclusion, the study clarified the importance of leptin levels during pregnancy period in primiparous rabbit does through its relationship with blood parameters and the productive performance of both dam and the kits. However, its relationship with these parameters need further studies, especially, studies on rabbits are very rare and most of them have been conducted on other species.","PeriodicalId":11684,"journal":{"name":"Egyptian Journal of Rabbit Science","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73100840","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}

The experiment aimed at studying the effect of linseed oil at the rate of 1,2, 3 and 4% on their productive performance, carcass characteristics, some blood parameters, T3 and T4 as well as histological changes in the liver and testis of the tested animals. \u0000            Adding linseed oil to rabbit diets at the level of 2% improved significantly (P≤0.05) LBW compared to the control one as well as the other 3 levels of oil. The DWG showed no significant differences among the five experimental groups, except for the treatment of 2% linseed oil which significantly differed (P≤0.05) compared to the control group and the other 3 treatments of linseed oil. The highest significant BWG value (P≤0.05) was obtained with adding 2% linseed oil to the diet, while the lowest value obtained with the 4% oil treatment, but without significant difference with other 2 oil levels or the control one. The increase in BWG came in a descending order with increasing oil % in the diet. The amount of daily feed intake remarkably (P≤0.05) decreased than the control one with age when diets contained 2 and 3% linseed oil. The pest (P≤0.05) FCR (3.58) was obtained in the group of 2% linseed oil, while the worst (4.36) was recorded with adding 4% linseed oil to the diets. Live body weight at slaughtering time as well as carcass weight insignificantly differed among the five tested groups. \u0000Adding linseed oil to the diets of tested rabbits improved carcass weight generally over that of the control one. The group fed 2% linseed oil diet gave the highest carcass weight. Regarding weights of carcass organs, i.e. head, heart, abdominal fat and back quarters, except back quarters yield, showed no significant differences among the 5 different treatments.
