Agricultural Research Center , Dokki, GizaJournal Article20190827This studyiwasiconducted to evaluate the effectsiof added two levels of chamomile flowers to the rations of Baladi calves on growth performance, feedingivalues as well as some rumen and blood parameters. A total of 21 calves with an averageilive body weight of 100 kg, with an averageiage of 3-4 months were used in a feeding trial that lasted 360-d duration period. Animals wereidivided into threeisimilar groups (7 in each group) andifed their basal ration according to NRC (1996) recommendations. The dietsicontained 0, 5 and 10 g chamomile flowers / 100 kg BW/day for treatments G<sub>1 </sub>(control), G<sub>2</sub> and G<sub>3</sub>, respectively. The basal ration (control) was formulated from concentrate feed mixture (CFM), berseem hay (BH) andirice straw (RS). In addition, 9 rams were used to evaluate the digestibility and feeding values of the experimental rations. Measurements of some rumen fermentation parameters and blood constitutes were determined as well. Results ishowed that the digestionicoefficients of all nutrientsiand feeding valuesiwere improved withiincreasing the leveliof chamomile (0, 5 and 10g / 100 kg BW/ day) in the rations and theidifferences were mostlyisignificantly between controliration and the high leveliof chamomile-ration. The results of rumen parameters showed that pH values, ammonia-N and TVFAs concentrations slightly changed over most sampling times among dietary treatments were observed, otherwise at sampling time (2hr post feeding), ammonia-N was significantly lower with the high chamomile ration than that of control one. However, addition of chamomile had significantly increased total volatile acids (TVFA's) concentrations at 4 hrs post feeding. The highest values of protozoa count and microbial protein at 4 hrs were recorded with G<sub>3</sub> (0.840 and 684, respectively) and the lowest values were recorded with G<sub>1</sub> (0.672 and 0.576, respectively). Regarding growth performance, the daily body gain (DBG) was higher with increasing chamomile level during the different growth periods. During 1period, the DBG in G<sub>2</sub> was insignificantly higher than G<sub>1</sub> but G<sub>3</sub> was significant higher than G<sub>1</sub>. While, DBG during the second period was not significantly different among treatments. During the whole period, the final body weight was significantly higher with the two tested rations compared with that of unsupplemented one (control). Calves consumed approximately similar quantity of DM as g/ kgw<sup>0.75</sup> since all calves had similar body weight. The daily DM intake expressed as g/kg w<sup>0.75</sup> during the first period was higher than that consumed during the second period in all treatments. Most of the blood constituents were not significantly affected by adding chamomile flowers in the tested rations. The values of Hb and RBC,s tended to increase in animals given chamomile flowers and the differences were significant only for blood Hb concentration. Moreover, serum total protein and globulin concentrations were significantly higher with the high level of chamomile ration compared with control. Meanwhile, the concentrations of total lipids and cholesterol as well as the enzymes activity (GOT, GPT) were lower with the chamomile supplemented rations (G<sub>2</sub> and G<sub>3</sub>) than those of control group (G<sub>1</sub>) and the differences were significant respecting total lipid concentration only. The economic efficiency was improved with increasing the level of chamomile in calve rations ( 3.546, 3.570 and 3.641for G1, G2 and G3, respectively).https://jappmu.journals.ekb.eg/article_46064_8da0614992820ea2d3a1df531f702e8e.pdfMansoura University, Faculty of AgricultureJournal of Animal and Poultry Production2090-364281220171201Effect of Using Tanniniferous Plants Shrubs in Feeding Barki Ewes on some Productive and Physiological Parameters4674764606510.21608/jappmu.2017.46065ENE.

This study aimed at exploring the possibility of complete replacement of berseem hay (control) in the diet by leaves and stems of tanniniferous shrubs plants and its effect on productive and physiological responses, in addition to some milk and blood biochemical constituents. Forty mature healthy Barki ewes at late pregnancy, 3-4 years old with an average live body weight (LBW) 51.5±0.46 kg were randomly divided into 4 similar groups. The 1<sup>st</sup> group (Hay) was fed the control diet which consisted of 40% concentrate feed mixture plus 60% berseem hay (BH), while in the 2<sup>nd</sup>,3<sup>rd</sup> and 4<sup>th</sup> groups, BH as percentage was replaced by <em>Acacia</em>, <em>Atriplex</em> and <em>Cassava</em> respectively. Body weight of ewes and their offsprings were recorded biweekly. Milk yield was measured weekly and milk samples of each animal were taken for milk analysis. Blood samples were collected biweekly for measuring some hematological and biochemical parameters. Feeding tanniniferous plants shrubs did not result in significant differences on body weight of Barki ewes and their offsprings, while improved milk productivity and increased milk protein and lactose. According to the results of biochemical parameters of blood, it could be concluded that feeding tanniniferous plants shrubs did not cause any negative effects on blood parameters of the experimental animals under the present study.https://jappmu.journals.ekb.eg/article_46065_c942340466a9356aabacafc906de6c8f.pdfMansoura University, Faculty of AgricultureJournal of Animal and Poultry Production2090-364281220171201Estimate of Direct and Maternal Genetic Parameters for some Production and Reproduction Traits in Friesian COWS through Sire and Animal Models4774824606710.21608/jappmu.2017.46067ENH.

Data were covered the period from 1985 to 2003. A total records were 2302 of 755 cows were sired by 45 bulls were analyzed using LSMLMW and MTDFREML programes. Unadjusted means of MY, LP, DP, DO and CI were 4875 kg, 333 d, 72 d, 119 d and 405d, respectively. Sire heritability were 0.43, 0.28, 0.30, 0.26 and 0.24 for MY, LP, DP, DO and CI, respectively. In this respect, direct and maternal heritabilities for the same traits were 0.34, 0.17, 0.13, 0.15 and 0.17, and 0.11, 0.15, 0.14 0.23 and 0.10, respectively. For sire model, genetic correlations among productive traits ranged from -0.30 (LP and DP) to 0.76 (MY and LP), while between reproductive and productive traits were postive and high (0.86 to 0.93) except DP and each of DO and CI were low and positive (0.13 and 0.09), respectively. The same trend as in the sire model was obtained also in the direct genetic correlations (ra1a2) among the same previous traits. Likewise estimates of maternal genetic correlations (rm1m2) were the similar the direct genetic correlations. Accuracy of decled breeding value, ranged from 35 to 88, 72 to 89 and 37 to 87 for sires, cows and dams, respectively, for different studied traits. This indicte that genetic improvement should be preferable realized through cows which the minimum of acurrecy was highest comparing to sires or dams. The present high estimates of genetic correlations between MY, LP and reproductive traits (DO and CI) that offer the possibility genetic improvement if selection for MY avaiable. Also the actual estimate of maternal heritability suggested that the maternal effects take into account in the analysis models and selection for productive and reproductive traits in Friesian cows cows in Egypt.https://jappmu.journals.ekb.eg/article_46067_3659c9f08c5e1da32604090a22531291.pdfMansoura University, Faculty of AgricultureJournal of Animal and Poultry Production2090-364281220171201Effect of Housing System on Japanese Quail Performance4834904606810.21608/jappmu.2017.46068ENY. K.BadawiAnimal Production Research Institute, Agric. Res. Cent., Min. of Agric., Dokki, Giza, EGYPTJournal Article20190827This study was conducted to investigate the effect of two different housing systems; floor pens vs. battery cages on productive traits in Japanese quail. Three hundred, one day old chicks were individually weighed and randomly divided into two equal experimental groups according to housing system (150 birds in each group), each group was randomly assigned to three replicates. Body weight, body weight gain, feed consumption, feed conversion ratio and mortality rates were recorded weekly during the first experimental period. At the end of the growing period slaughter test was carried out to estimate carcass quality characteristics. Feed intake , feed conversion ratio and mortality rates were recorded. The dressed carcass, heart, liver, head and gizzard were weighed. The pooled weight of heart, liver, gizzard, and edible meat were designated as total edible meat (TEM). Using floor pens improved Gizzard weight, and gizzard percentage values compared to battery cages. Egg production, and egg quality traits, were estimated during the second experimental period. It was concluded that housing system had no significant effect on productive most traits of Japanese quails. Using floor pens improved gizzard weight, gizzard percentage, egg yolk weight and egg yolk percentage values of floor pen reared quails compared to battery cages. It was concluded that housing system had no significant effect on most of productive traits of Japanese quailhttps://jappmu.journals.ekb.eg/article_46068_bfd99da87b5b05613d0eb277e171a216.pdfMansoura University, Faculty of AgricultureJournal of Animal and Poultry Production2090-364281220171201Concentration Dependent of Lactoferrin can Improve In vitro Maturation, Fertilization and Embryonic Development of Buffalo Oocytes.4914944607110.21608/jappmu.2017.46071ENY.

The current study aims to investigate the effect of different concentrations of bovine lactoferrin (bLF) on <em>in vitro</em> maturation, <em>in vitro</em> fertilization and embryo development of Egyptian buffalo oocytes. Each of<em> in vitro</em> maturation, <em>in vitro</em> fertilization (IVF) and embryonic development medium was supplemented with bLF at concentrations of zero (control), 0.01, 0.03, 0.05 and 0.1 mg/ml for each trail. Lactoferrin insignificantly enhanced maturation rates compared with control group. The highest rates (p<0.001) of IVF (52.73 and 43.33%) were observed for both 0.03 and 0.05 mg/ml supplementations to IVF medium. All bLF levels increased (p<0.0001) cleavage rate and proportion of embryos at both morula and blastocyst (p<0.05) stages than the control medium with advantage to 0.03 mg/ml concentration along examined developmental stages. The current study revealed that low levels of bovine bLF has a supportive effect (especially 0.03 mg/ml) on each of IVF media and embryo development of the Egyptian buffalo oocytes.https://jappmu.journals.ekb.eg/article_46071_9195c65305dcac1ab8a92711cdf7c2d2.pdf
