A. TahaDesert Research Center- Cairo-Egypt.Journal Article20191101Eighteen adult non-pregnant; non-lactating Barki ewes, aged 3-4 years with initial body weight of 36.71 ± 4.798 (kg) were randomly divided to three groups (n=6). The first group (G1) was kept unshorn along two years (spring 2016 to spring 2018), the second group (G2) was shorn once in the common time of spring (2017) while the third (G3) was shorn biannually in spring and autumn (2017) to investigate the effects of biannual shearing on body weight, some fleece traits, wool production and some wool traits. Mid-side samples of about 200 gram of wool were taken from each animal just before 2018 shearing to determine the studied wool traits. No significant differences were detected among G1, G2 and G3 in final body weight. Biannual shearing improved (P<0.05) the body weight gain, wool yield, cotting grade, the uniformity of fiber diameter in G3 fleeces compared with the corresponding values of G1 and G2. Moreover, G2 and G3 produced more clean wool, higher percentages of fine fibers, stronger staples with higher elongation rate than G1 (P<0.05). Mean fiber diameter, Kemp score, prickle factor and medullation index declined (P<0.05) in G2 and G3 compared with G1. The results indicated that biannual shearing as a management procedure could be conducted with no expected negative effects on most of the wool traits. It might also be useful in improving body weight gain, clean wool production, wool yield, uniformity of fiber diameters, staple strength and elongation rate.https://jappmu.journals.ekb.eg/article_64347_5ba81cf92ccc019aba5a7f5ccc4f52ae.pdfMansoura University, Faculty of AgricultureJournal of Animal and Poultry Production2090-3642101120191101Impact of Dietary Supplementation with Ginseng or/and Garlic on Growth Performance, Blood Biochemical Parameters and Carcass Traits of Growing Male V-Line Rabbits3453506786410.21608/jappmu.2019.67864ENAya M.Abdel-RahmanAnimal Production Research Institute, Dokki, Giza 12619, EgyptA.

Z.MehrezDepartment of Animal Production, Faculty of Agriculture, Mansoura University, Mansoura 35516, EgyptJournal Article20191105This study was conducted to investigate the effect of adding ginseng or/and garlic powder in the diet on growth performance, biochemical parameters and carcass traits of growing male rabbits. Weaned V-line male rabbits (n=48) were divided into four groups. They were assigned at random to receive a basal diet without supplementation (control group), supplemented with 50mg Ginseng or/and 5gm Garlic/kg diet. Growth performance parameters were recorded at age intervals from 5-14wk. Serum biochemical and carcass traits were determined at 14wk of age. Results show that dietary fortification with ginseng or/and garlic caused a significant increase (P≤0.05) in live body weight and body weight gain of male rabbits at 14wk old. Rabbits fed the diets supplemented with garlic alone or combined with ginseng displayed significantly better (P≤0.05) means of feed conversion ratio. Rabbits fed the ginseng or garlic plus ginseng-supplemented diets displayed significantly higher (P≤0.05) serum triglycerides and cholesterol levels. On the other hand, rabbits fed garlic or garlic plus ginseng supplemented diets showed significantly lower (P≤0.05) levels of serum low-density lipoprotein. Dietary supplementation with ginseng and garlic singly or in combination did not significantly affect dressing-out percentage, and weights of carcass yield, hind parts and edible organs of rabbits. However, rabbit fed the garlic-fortified diet displayed significantly heavier (P≤0.05) testes than did the control group and other experimental groups. The current study indicated that addition of ginseng or/and garlic powder in the diet increased growth performance without any adverse effect on immunity and carcass traits of growing V-line male rabbits.https://jappmu.journals.ekb.eg/article_67864_a71a29bad99cbef773f244cfa47782ac.pdfMansoura University, Faculty of AgricultureJournal of Animal and Poultry Production2090-3642101120191101Effects of Zingiber Officinale and Ambrosia Maritima on some Physiological Parameters and Kidney Structure in Rats3513556787110.21608/jappmu.2019.67871ENA. A.Abd El HamidAnimal production Department, Faculty of Agriculture Al- Azhar University, Cairo, EgyptJournal Article20191115The present work was carried out to investigate the effect of ZOR Roscoe (ZOR), AML L (AML) and their mixture on some physiological parameters and kidney structure of male albino rats. This study was undertoken in the animal house belong to Animal Production Department, Faculty of Agriculture, Al-Azhar University. Twenty-four male albino rats with an average body weight 100-130 g. The animals were divided into 4 similar groups group<sub>1</sub> (Control untreated group), group<sub>2</sub>, ( rats fed with diet contain 5% ZOR Roscoe), group<sub>3</sub> (rats fed on diet contain 5% AML L) and group<sub>4</sub> (rats fed on diet containg 2.5% ZOR Roscoe +2.5% AML L.). During the whole experimental period blood samples were collected and serum was analyzed for concentration of glucose, cholesterol, triglyceride , urea and criatinin. At the end of the experiment, rats were scarificed to obtain the kidneys. Results indicated that treatment of rats with zingiber officinal and AML for 8 Weeks showed mild ischemic charges of some glomeruli and tubules in the cortex of the kidney, Meanwhile mix with zingiber officinal and AML showed minimal ischemic changes of some glomeruli and tubules in the cortex of the kidney. All medicinal plants treatment had hypochlosterolemic and hypolepidimic effects being the highest for the comparing treatment. Treatment of rats with medicinal plants for 8 weeks significantly increased serum urea and creatinine concentration.https://jappmu.journals.ekb.eg/article_67871_ab464dce5f3314a0085d19048997bf7b.pdf
