The present study aimed to evaluate the impact of different levels of dietary replacement of barely by prickly pear fruits (PPF) and peel (PPP) on growth performance, carcass traits and antioxidant status of rabbits. 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.
本试验旨在评价不同水平的刺梨果实(PPF)和果皮(PPP)对家兔生长性能、胴体性状和抗氧化能力的影响。选取75只平均初始体重为(596.00±13.05 g)的5周龄断奶雄性新西兰白兔(NZW),随机分为5个试验组,每组15只。配制5种试验饲粮;第一组作为对照日粮(0% PPF和0% PPP)。其余4种饲粮分别以25%和50%的PPF或PPP水平替代大麦。结果表明,PPF和PPP富含维生素C(2.4、2.8μg/100g)、维生素E(25、23μg/100g)和维生素A(10、13μg/100g)。PPF总能(GE)含量高于PPP和大麦。结果还表明,在(9 ~ 13)周龄和(5 ~ 13)周龄期间,与对照组相比,饲粮中PPF和PPP各测试水平(25%和50%)对生长兔的平均体重、体增重、FI和FCR均无影响(P<0.05)。在整个生长期内(5-13周龄),与其他试验组(包括对照组)相比,在饲粮中添加50% PPF或50% PPP可显著提高生长兔的平均体增重和饲料转化率。与对照组相比,添加PPF(25%和50%)或PPP(25%和50%)对OM、CP、EE和CF的消化率无显著影响。此外,对照组和其他测试组的TDN和DE在各测试水平下均含有PPF或PPP(25%或50%),差异均不显著。25%和50% PPP饲粮中NH3-N浓度最低(P<0.05), 25% PPP饲粮中TVFA值最高(P<0.05)。饲粮中PPF含量为50%或PPP含量为50%的家兔肝脏、心脏和可食性脏器均较对照组重(P<0.05),腹部脂肪含量最低(P<0.05),血清抗氧化标志物和酶(TAC、GSH-Px、SOD和CAT)含量较高(P<0.05)。与对照组相比,PPF和PPP添加组血浆甘油三酯、胆固醇和LDL浓度降低(P<0.05), HDL浓度升高(P<0.05)。与对照组相比,在家兔日粮中添加25%或50%的PPF或PPP可提高经济效益和净收入。综上所述,在本试验条件下,PPF或PPP可在生长兔饲粮中添加50%以上的大麦,在不显著损害生长兔生长性能的情况下,达到较好的抗氧化状态和较高的饲粮经济效益。

The present study was conducted in the experimental farm of Animal Production Department, Faculty of Agriculture, South Valley University, Qena, Egypt, where there is a prevailing a subtropical climate. The experiment started in 15th of January 2012 to the end of May 2012. The work aimed to study the effect of zinc oxide (Zn O) levels supplementation on semen quality and fertility rate of buck New Zealand White (NZW) rabbits under subtropical conditions. A total number of thirty buck rabbits (16 weeks of age and average body weight 2368±14.21) were randomly divided into three equal treatments (10 bucks of each) without significant difference in average body weight between treatments. The 1st treatment (T1), rabbits saved as control (0 g Zn O supplement/ kg diet). The 2nd and 3rd treatments (T2 and T3), rabbits were fed with basal diet containing 75 and 150 ppm Zn O/ kg diet, respectively (0.096 and 0.192 g Zn O supplement/ kg diet, respectively). The results indicated that all the physical semen characteristics of NZW were significantly (P<0.05) improved by Zn O supplementation of buck NZW rabbits except ejaculate volume and sperm motility. Sperm concentration, total sperm count and live spermatozoa were significantly increased (P≤0.05) in the bucks of T2 and T3 as compared to the control ones. Moreover, fertility rate and litter size at birth were higher (P<0.05) in the bucks of T2 and T3 (Zn O supplementation) as compared to the bucks in T1 (control group). In conclusion, adding 75 or 150 ppm zinc O/ kg diet improved the physical characteristics of semen quality and fertility rate of buck NZW rabbits under subtropical conditions.
本研究在埃及Qena的南谷大学农学院动物生产系实验农场进行,那里主要是亚热带气候。实验开始于2012年1月15日至2012年5月底。本试验旨在研究亚热带条件下饲粮中添加氧化锌(Zn O)对新西兰白兔精液质量和受精率的影响。选取16周龄、平均体重2368±14.21的雄兔30只,随机分为3组,每组10雄兔,各组平均体重无显著差异。第1次处理(T1),对照组(添加0 g Zn / kg日粮)。第2和第3处理(T2和T3)分别饲喂锌含量为75和150 ppm / kg的基础饲粮(锌添加量分别为0.096和0.192 g / kg)。结果表明:补锌对NZW雄兔除射精量和精子活力外,其他各项精液物理性状均有显著改善(P<0.05)。T2和T3雄鹿的精子浓度、总精子数和活精子数均显著高于对照组(P≤0.05)。T2组和T3组雄鹿的产仔率和窝产仔数均高于T1组(对照组)(P<0.05)。由此可见,在亚热带条件下,饲粮中添加75或150 ppm的锌可改善雄NZW兔的精液质量和受精率。

A total number of 30 primiparous New Zealand White (NZW) pregnant rabbit, does were used in the current study to evaluate the changes of leptin levels during pregnancy in relation to each of physiological, reproductive and productive performance of does. 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. The 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. In 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.

本研究选用30只新西兰白(NZW)初产妊娠兔,评价妊娠期间瘦素水平与妊娠兔生理、生殖和生产性能的关系。5 ~ 6月龄,平均体重3098.15±20.24 g。测定妊娠13、21、28天及点火时血浆生化指标。测定母猪体重、产仔数、产仔重、产奶量和乳成分。结果表明,瘦素水平在妊娠期间略有升高,在妊娠第28天达到最高值(2.91 ng/ml),随后在分娩当天下降。此外,瘦素水平与GST呈正相关,与h2o2和MDA呈负相关。妊娠第28天h2o2和MDA水平较低,而瘦素达到最高水平(2.91 ng/ml)。这表明,瘦素可能在抗氧化和自由基系统中起重要作用。血蛋白(TP、Alb和A/G, Glb除外)与瘦素水平呈正相关。这表明,瘦素可能会干扰血液蛋白的代谢。此外,瘦素与血浆TL、TG和Glu呈负相关,在妊娠期间下降,在妊娠第28天达到最低点(分别为154.47、135.11和106.55 mg/dl)。此外,瘦素也与BUN水平呈负相关,在怀孕第13和21天时BUN水平高于正常范围。随后在第28天显著下降。此外,CR水平与瘦素水平呈负相关。肝酶(AST和ALT)与瘦素水平呈负相关。这些酶在妊娠期间下降,分别在妊娠第28天出现较低水平。此外,母鼠体重、窝重和体型与瘦素水平呈正相关,因为瘦素通过控制脂肪组织的质量来调节体重。此外,瘦素水平与产奶量、MF、ML和乳灰分呈负相关。相反,MP、MTS和MSNF与瘦素水平呈正相关。综上所述,本研究通过瘦素水平与血液参数及母兔和仔兔生产性能的关系,阐明了妊娠期初产兔瘦素水平的重要性。但其与这些参数的关系还有待进一步研究,特别是对家兔的研究非常少,大多是对其他物种的研究。

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.

A number of eighty growing NZW rabbits at 5 weeks age and 620 ± 30 g average live body weight were weighed and distributed into five experimental groups. 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.             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. Adding 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. Weights of liver, kidney and testis and their yield as well as dressing percentage and back quarters yield noticeably increased (P≤0.05) in the group of 2% linseed oil diet compared to the control one and other 3 linseed oil treatment groups. Diet supplemented with linseed oil generally increased blood TP, Alb., HDL, LDL, T3 and T4 values compared to the control group, while it decreased glob. and cholesterol as well as TG in the two high levels of oil supplementation only. The experimental dietary treatments showed beneficial effect of omega-3-PUFA on liver and testis structures of rabbits fed diet supplemented with linseed oil at the rate of 2 and 3% since it did not show any abnormality in the histological structure of both organs. Conclusively, on the light of the aforementioned results, it could be concluded that addition of linseed oil to growing rabbit diets at the rate of 2 followed by 3% resulted in lowering daily feed intake accompanied by improved feed conversion ratio and increase in body weight gain without adverse effects on hematological aspects.

取5周龄、平均活重620±30 g的生长獭兔80只,称重后分为5个试验组。本试验旨在研究添加比例为1、2、3和4%的亚麻籽油对试验动物生产性能、胴体特性、部分血液参数、T3和T4以及肝脏和睾丸组织学变化的影响。饲粮中添加2%水平的亚麻籽油,与对照组和其他3个水平的油相比,显著提高了家兔的体重(P≤0.05)。除2%亚麻油处理与对照组及其他3个亚麻油处理相比显著差异(P≤0.05)外,5个试验组间DWG无显著差异。饲粮中添加2%亚麻籽油的体重增重值最高(P≤0.05),添加4%亚麻籽油的体重增重值最低,但与其他2种油水平或对照差异不显著。体重增重随日粮中油脂含量的增加呈递减趋势。饲粮中添加2%和3%亚麻籽油时,日采食量随日龄显著低于对照组(P≤0.05)。饲粮中添加2%亚麻籽油组的虫率为3.58 (P≤0.05),添加4%亚麻籽油组最差(4.36)。屠宰时活重和胴体重在5个试验组间差异不显著。在饲粮中添加亚麻籽油对试验兔胴体质量的改善总体优于对照组。饲粮中添加2%亚麻籽油的组胴体重最高。在胴体各器官(头、心、腹脂肪和背部)重量方面,除背部产量外,5个处理间均无显著差异。与对照组和其他3个亚麻籽油处理组相比,2%亚麻籽油饲粮组肝脏、肾脏和睾丸重量及其产量、屠宰率和后躯产量显著提高(P≤0.05)。饲粮中添加亚麻籽油可提高血TP、Alb含量。HDL、LDL、T3、T4值较对照组明显降低。和胆固醇以及甘油三酯在两种高水平的油的补充。试验饲粮处理显示,在饲粮中添加2%和3%亚麻籽油时,欧米茄-3- pufa对家兔肝脏和睾丸的组织结构都有有益的影响,因为这两种器官的组织结构都没有出现异常。综上所述,在生长兔饲粮中添加2%的亚麻籽油,再添加3%的亚麻籽油,可以降低日采食量,提高饲料系数,增加体重,但不会对血液学产生不利影响。此外,同样的处理诱导雄性的胴体特征以及肝脏和睾丸的组织学结构变化最为显著。

Twenty five aging V-lines buck rabbits, 24-month of age weighing at average 3230±41.7 g and 30 multiparous does aged 7- month at average body weight 3150±38.5 g were used. Bucks were randomly distributed to five equal groups for orally administered with 3 ml of different sources of refined vegetable oil/buck/daily, for seven consecutive weeks prior to semen collection as follows: group: 1 were given  sterilized water and served as control (C), group; 2 sesame oil (Ses), group: 3 linseed oil (Lin), group: 4 sunflower oil (Sun), group: 5 mixture oil (Mix) oil containing equal portions of Ses, Lin and Sun. Serum testosterone, follicles stimulating hormone (FSH), luteinizing hormone (LH), prostaglandin (PGF2α), total antioxidant enzymes (TAC) and malonylaldehayed (MAD), reaction time(RT) and semen quality were measured. Results revealed that as follows: 1-      Concentrations of serum testosterone, FSH and LH were significantly (P≤0.01) improved in treated groups compared with control group otherwise PGF2α recorded highest values in all treated groups. 2-      Aging buck rabbits consumed either Lin or Mix oils recorded the best values of serum testosterone, FSH and LH hormones concentration. 3-      All experimental treated groups represented significant (P≤0.01) increase of TAC and significant (P≤0.01) reduction in MAD compared with control. 4-      Reaction time, advanced motility, ejaculate volume, sperm concentration, abnormal sperm, dead sperm, fertility rate and litter size at birth were statistically (P≤0.01) improved for groups supplemented with Lin and Mix oils compared to the other treated groups and control. Conclusively, from these results it could be concludedthat supplementing aging buck rabbits with Lin or Mix oils (rich source of n-6 and n-3) for 7 consecutive weeks before mating or artificial insemination, had improved the reproductive performance, libido, antioxidant status and fertility traits.
选用24月龄平均体重3230±41.7 g的衰老v系雄兔25只和平均体重3150±38.5 g的7月龄多胎雄兔30只。雄鹿随机分为5组,在采集精液前连续7周口服不同来源的精制植物油3 ml /雄鹿/d,分别为:组1只雄鹿给予无菌水作为对照(C);2香油(Ses),组:3亚麻籽油(Lin),组:4葵花籽油(Sun),组:5混合油(Mix),油中含有等量的Ses, Lin和Sun。测定血清睾酮、促卵泡激素(FSH)、促黄体生成素(LH)、前列腺素(PGF2α)、总抗氧化酶(TAC)、丙二醛脂(MAD)、反应时间(RT)和精液质量。结果表明:1-与对照组相比,各治疗组血清睾酮、FSH和LH浓度均显著(P≤0.01)提高,PGF2α均最高。2-老龄雄兔的血清睾酮、卵泡刺激素和黄体生成素浓度均以林氏油和混合油为最佳。3-与对照组相比,各试验组TAC显著(P≤0.01)升高,MAD显著(P≤0.01)降低。4-与其他处理组和对照组相比,添加林油组和混合油组的反应时间、提前运动能力、射精量、精子浓度、异常精子、死精子、生育率和出生产仔数均有统计学意义(P≤0.01)的提高。综上所述,在交配前或人工授精前连续7周添加富含n-6和n-3的林油或混合油,可改善衰老雄兔的繁殖性能、性欲、抗氧化能力和生育性状。

This study carried out to evaluate the effect of feeding diets containing olive cake meal (OCM) at 10 % and 20 % with or without citric acid at levels 0.1 % or 0.2 % on growing rabbits performance. One hundred and five weaning New Zealand white (NZW) rabbits about 4 weeks old were allotted at random to seven experimental groups with 15 rabbits in each group contained  three replicates (  five rabbits in each ) in a growth trail lasted for forty days. The experimental diets were as follows: Diet 1 was used as a  control without adding olive cake or citric acid, and Diets 2, 3 and 4 : contained 10 %  olive cake and were supplemented with zero, 0.1 and 0.2 % citric acid respectively, Diets 5, 6 and 7 : contain 20 %  olive cake and  were supplemented with zero, 0.1 and 0.2 % citric acid respectively.  Results could be summarized as follows:Addition of olive cake plus citric acid to growing rabbit diets significantly increased   live body weight (LBW) and daily weight gain (DWG). Feed conversion ratio (FCR) was improved and mean values of  feed intake (FI)were increased along with adding 10% olive cake   plus 0.1% citric acid in the rabbit diets . Economic efficiency percentage (EEf), relative economic efficiency (REE) and performance index (PI) were higher in growing rabbits fed diets containing 10% olive cake meal   plus 0.1%citric acid than the other groups. A significant increase in apparent digestibility coefficients of CF, EE, NFE, and TDN were detected while, there was insignificant increase in DM, OM, CP, DCP and DE % and apparent digestibility coefficient with addition olive cake    plus citric in the rabbit diets.  Carcass, liver, heart, giblets and dressing percentages in rabbits fed 10% olive cake recorded  higher values compared with other dietary treatments. Cholesterol and triglycerides in rabbits fed diet containing 10% olive cake without or with 0.1% citric acid showed lower values compared to the other treatment. Total lipids, total protein, albumin, globulin, albumin /globulin ratio, and liver enzymes activity ALT and AST levels were not affected by the dietary treatments. Conclusively, dietary incorporation of 10% olive cake meal supplemented with 0.1% citric acid could be recommended to improve growth performance, feed utilization  and economic return of growing rabbits production.
本试验旨在评价添加10%和20%橄榄饼粕(OCM)和不添加0.1%或0.2%柠檬酸对生长兔生产性能的影响。选取4周龄左右的断奶新西兰白兔105只,随机分为7个试验组,每组15只,每组3个重复,每组5只,试验期为40 d。试验饲粮为对照,饲粮1不添加橄榄饼和柠檬酸,饲粮2、3、4为10%橄榄饼,分别添加0、0.1、0.2%柠檬酸,饲粮5、6、7为20%橄榄饼,分别添加0、0.1、0.2%柠檬酸。结果表明:在生长兔饲粮中添加橄榄饼和柠檬酸可显著提高生长兔的活重和日增重。在家兔饲粮中添加10%橄榄饼+ 0.1%柠檬酸可提高饲料系数(FCR)和平均采食量(FI)。10%橄榄饼粕加0.1%柠檬酸组的经济效率率(EEf)、相对经济效率(REE)和生产性能指数(PI)均高于其他各组。饲粮中添加橄榄饼加柠檬酸显著提高了CF、EE、NFE和TDN的表观消化率系数,而DM、OM、CP、DCP和DE %及表观消化率系数无显著升高。饲喂10%橄榄饼的兔胴体率、肝脏率、心脏率、内脏率和屠宰率均高于其他饲粮处理。饲粮中添加10%橄榄饼,不添加0.1%柠檬酸或添加0.1%柠檬酸的家兔的胆固醇和甘油三酯值低于其他处理。总脂、总蛋白、白蛋白、球蛋白、白蛋白/球蛋白比和肝酶活性、ALT和AST水平不受饲料处理的影响。综上所述,饲粮中添加10%橄榄饼粕和0.1%柠檬酸可提高生长兔的生长性能、饲料利用率和经济效益。
