Abo-BakrAnimal and Poultry Nutrition Department, Desert Research Center, Mataria, Cairo, EgyptJournal Article20190716The objectives of this work were to study productive performance and blood biochemical alterations in Barki ewes fed silage from salt tolerant plants mixture (SSP), and its impact on the growth rate and blood biochemical parameters of neonatal lambs. Forty-eight adult estrus synchronized Barki ewes at 2–3 years old with average of 38.39±1.85 kg live body weight were randomly divided into two experimental groups (24 in each). The first group (BH) was fed a control diet of berseem (<em>Trofolium alexandrenum)</em> hay and commercial concentrate, while the second one (SSP) was fed silage made from a mixture of four salt-tolerant plants (<em>Atriplex halimus</em> 50%; <em>Beta vulgaris</em> 25%; <em>Pearl millet</em> 15% and <em>Carthamus tinctorius</em> 10%). All born lambs were housed with their mothers during neonatal period. Live body weight changes, blood biochemical parameters of Barki ewes and their lambs were recorded immediately after birth and weekly until the end of the neonatal period (28 d post-partum). Results showed that during the first month of lactation, ewes of both groups lost weight without any significant effect of treatment on total weight loss. Male and female lambs obtained from ewes fed SSP had higher birth and final body weight. However, lambs of ewes fed hay showed insignificantly higher daily gain and total gain. There was no effect of age on total gain and daily gain. Male lambs were heavier at birth than females in both groups and consistently higher allover the neonatal period. Milk yield and composition were not affected by dietary treatment, except for ash percentage that increased in milk of ewes fed SSP ration. Ewes fed SSP had significantly lower concentrations of plasma total proteins (TP) and albumin (AL), while insignificantly lowered concentration of globulin (GL) and AL/GL ratio than. Concentration of TP was lower (P<0.05) in lambs of SSP group. Also in lambs, the effect of age was significant (P<0.01) on TP, GL and AL/GL ratio, with the higher values were recorded at birth and at the first week of age. Ewes of SSP group had significantly lower values of plasma glucose and total lipids, while cholesterol was not affected by treatment. Time after parturition affected only total lipids. Lambs responded to treatment like mothers, but day after lambing had no effect. Ewes of SSP group recorded significantly higher values of liver and kidney function parameters in plasma (AST, ALT, ALP. urea and creatinine), being within the normal range. In conclusion, utilization of silage made from salt-tolerant plants as animal feeds seems to be alternative and acceptable feed resources without serious adverse effects on ewes and their lambs during neonatal period under harsh conditions.Mansoura University, Faculty of AgricultureJournal of Animal and Poultry Production2090-36429820180801Effectivenesss of some Feed Additives for Detoxification of Aflatoxin B1 in Laying Hens3453564113510.21608/jappmu.2018.41135ENKh.

R.El-GogaryPoultry Production Dept., Fac. of Agric., Mans. UniversityRdwa F. S. A.IsmailPoultry Production Dept., Fac. of Agric., Mans. UniversityJournal Article20190716An experiment was undertaken to study the influence of dietary Aaflatoxin B1 (AFB1) on layer performance and the efficacy of some non-nutritive feed additives such as chemical Hydrated sodium calcium Alumino Silicat (HSCAS), prebiotic Mannan-oligosaccharides (MOS) and lactobacillus acidophilus based probiotic (Biotop) to eliminate the adverse effects of AFB1 on productive and reproductive performance, egg quality and some blood constituents of local laying hens. A total number of 150 Dokki-4 hens plus 30 Dokki-4 cocks 28 weeks old, were divided into 5 groups of 3 replicates (10 hen +1 cock) and housed in floor pens .The remaining 15 cocks were also divided into 5 groups of 3 cocks each and reared separately in wire-cages for semen evaluation and fed the same treated diets. Birds were allotted on the following treatments basal diet ( without any additives), basal diet contaminated with 1 ppm aflatoxin B1/kg diet (AFB1-diet), AFB1-diet+5g HSCAS/kg diet, AFB1-diet+1gMos/kg diet and AFB1-diet+1g Biotop/kg diet. All experimental groups were fed on the experimental diets for 8 weeks as treated period, then they were fed free toxin diet for 4 weeks as a recovery period. Criteria of response were productive traits, egg quality, reproductive traits, semen evaluation, plasma biochemical constituents, AFB1 residue of egg yolk, New castle disease virus(NDV) antibodies titer and Protection percentage.The obtained results could be summarized as follows: The three AFB1-detoxifying agents applied significantly ameliorated the deleterious effect of AFB1, on final body weight and body weight gain. Addition with HSCAS, Mos or Biotop increased egg number/hen, average egg weight and egg mass. The best feed conversion ratio was obtained with the control group and dietary supplementation of HSCAS, Mos, or Biotop to AFB1–diet improved (FCR). Feed additives supplementations to AFB1-diet increased yolk weight, shell weight %, shell thickness, yolk color and yolk cholesterol. No significant difference due to treatments among albumen weight %, yolk index %, Haugh unit % and egg shape index %. At the end of the recovery period all egg quality parameters were recovered in groups fed on AFB1-diets during treated period except those which fed on AFB1-diet alone without feed additives for shell-thickness and yolk cholesterol content, where lower than the control and other treatments. The addition AFB1-detoxifying agents significantly improved semen volume, sperm concentration, motility rate, sperm abnormality and dead sperm. Hens fed diets supplemented with HSCAS, Mos or Biotop recorded higher values of fertility, hatchability and chick weight at hatch and lower values of chick abnormality compared to AFB1-diet. After recovery period alterations caused by AFB1-diet were negated for fertility, hatchability and chick weight at hatch but group previously fed AFB1-diet alone without any additives still recorded significantly higher value of chick abnormality compared with control and other treatments. Addition of HSCAS, Mos and Biotop significantly reduced the severity of AFB1 effects by increasing plasma total protein, albumin , globulin, Calcium and phosphorus and decreasing plasma AST,ALT,ALP, Creatinine, cholesterol and uric acid compared to AFB1-diet. AT the end of recovery period after the withdrawal of the contaminated feed , all groups fed the aflatoxicated diet with HSCAS, Mos or Biotop were recovered for all blood parameters except AST ,ALT ,cholesterol and creatinine. Addition of HSCAS, Mos or Biotop to the aflatoxin contaminated diet significantly ameliorated the harmful effect of aflatoxin on immune response to NDV in all examined samples for hen serm, egg yolk and post-hatch chick. Addition of feed additives (HSCAS, Mos or Biotop) significantly decreased the level of AFB1 residues in egg yolk compared to those fed AFB1-diet alone. After 4 weeks of recovery period, there were no residues in egg yolk. Conclusively, Feeding AFB1 contaminated diet (1 ppm Aflatoxin B1) resulted significant reduction in productive and reproductive performance of Dokki - 4 laying hens. Addition of HSCAS, Mos or Biotop to the aflatoxin contaminated diets significantly ameliorated the harmful effect of aflatoxin and can be recommended as antitoxin for detoxification of AFB1in diets of laying hens. Four weeks recovery period was quite good to improve the laying performance.Mansoura University, Faculty of AgricultureJournal of Animal and Poultry Production2090-36429820180801Changes in some Hemato-Biochemical Parameters and Hormonal Aspects in Baladi and Shami Kids in Relation to Their Mortality Rates during the Postnatal Period3573654113910.21608/jappmu.2018.41139ENM. .

Fifty pregnant does were randomly divided into two groups according to their breed Baladi and Shami 25 each group, Baladi does (averaged 21.12 kg LBW) while Shami does averaged 35.78 kg LBW, all animals were estrus synchronized using PGF2α during the Reproductive season from Sep to Feb 2016 and mated naturally. Gained kids were kept with their dams along the study period (Feb to Mar 2016)<em>.</em> After parturition, 101 kids (39 and 62, Baladi and Shami, respectively) were observed for one month of age<em>.</em> The mortality percentages for male and female kids were respectively 33<em>.</em>33% and 14<em>.</em>28% in Baladi while were 87<em>.</em>50% and 36<em>.</em>84% in Shami<em>.</em> Throughout the post-partum period haematological profile, glucose, cortisol and T3 were recorded at intervals of 1 day, 7<sup>th</sup>,14<sup>th</sup>,21<sup>th</sup> and 28<sup>th</sup> for all kids. the blood serum was then separated and kept at -25 ° C until the analysis was performed. In general, statistical analysis showed, the haematological profile of kids showed, the overall mean of WBCs (x10<sup>3</sup>/µL), RBCs, (x10<sup>6</sup>/µL), Hb (g/dl) and Hct (%) in Baladi and Shami kids , were (6.81 and 7.71), (8.70 and 8.44), (9.99 and 9.91), and (30.31 and 29.72), respectively, without significant difference. The obtained results showed that overall mean of glucose levels in Baladi and Shami kids, were (76.99 and 53.74), respectively with significant difference (P<0.051). The overall mean of cortisol in Baladi and Shami kids, were (487.32 and 496.86), respectively without significant difference. While The overall mean of T3 hormone of Baladi and Shami kids, were (1.37 and 1.35), respectively with significant difference (P<0.051). Kids that died then after had lower values of all studied parameters. The percentages decrease as compared to live kids within the 14 days in WBCs was between 25% and 41% in Baladi kids, while in Shami kids was between 20% and 41%. For RBCs, the decreased was between 28% and 31% in Baladi while was between 21% and 29% in Shami kids. The percentage decrease of Hb in Baladi kids was between 27% and 35% while in Shami kids was between 23% and 34%. The percentage decrease of Ht in Baladi kids was between 12% and 22% while in Shami kids was between 8.1% and 23%. The decrease percentage of glucose levels in Baladi were between 39% and 47%, while in Shami kids, was between 21.3% and 28.5%. The cortisol hormone in Baladi kids were between 28% and 34%, while in Shami kids were 21%-31%. For T3 hormone the decrease was between 18.5% and 19.2% in Baladi while was between 14.8% and 19.1% in Shami kids. it was concluded that Hematological profile, glucose, cortisol and T3 are indicative of health status of kids and had great effect on kids’ survivability. Baladi kids had significant higher values of both glucose and T3 than Shami ones that might indicate its higher ability to cope cold stress hence showed significant reduction of mortality rate.Mansoura University, Faculty of AgricultureJournal of Animal and Poultry Production2090-36429820180801Effect of Dipping Eggs Time into Different Glucose Solutions on Hatchability and Subsequent Growth Performance of Hatched Domyati Ducklings3673744114110.21608/jappmu.2018.41141ENA.

E.SarhanPoult. Prod. Dept. Fac. of Agric., Damietta Univ., Damietta, Egypt.Journal Article20190716This study amid to investigate the effect of dipping fertile Domyati duck eggs contained different glucose solutions (0.0, 5.0, 10.0 and 15.0%) and two dipping times (3 and 6 minutes) at the 24<sup>th</sup> day of incubation period on hatchability traits, duckling's quality and some blood parameters as well as subsequent growth performance of hatched ducklings and economic efficiency. A total number of 432 fertile eggs of Domyati duck at the 24<sup>th</sup> day of incubation period were distributed into eight experimental groups, each of three replicates in a factorial design (4 x 2). At the end of the 28<sup>th</sup> day of incubation period dead embryos, unhatched eggs, culled and healthy hatched ducklings were counted as well as hatched ducklings' length (cm) and weight (g) were recorded. Hatched ducklings of each experimental group were divided into three replicates and reared till 21 days of age to study the effect on subsequent growth performance and economic efficiency. Hatchability of fertile eggs was insignificantly improved by about 9.47 % of eggs dipped into 10.0% glucose solution as compared with those dipped into 0.0% glucose solution, while it was significantly decreased by dipping eggs into 15.0%glucose solution. Dead embryos (%) was insignificantly decreased by dipping eggs into 10.0%glucose solution than those dipped into 0.0% glucose solution only. Moreover, no significant changes in hatched weight, duckling's length (cm) and culled ducklings (%) due to dipping eggs into different glucose solutions. Dipping time of eggs had no significant effects on all studied hatching traits, while interaction between glucose solution and dipping time had significant effects on dead embryos, unhatched eggs and hatchability (%). Serum cholesterol level was significantly decreased in hatched ducklings produced from eggs dipped into 5.0 and 15.0% glucose solution comparing with those dipped into 0.0 and 10.0% glucose solutions at hatch. Dipping time of eggs had no significant effects on all studied blood parameters, while interaction between glucose solution and dipping time had significant effects on blood glucose and cholesterol. All studied growth performance traits were significantly affected due to dipping eggs into different glucose solutions, and the interaction between glucose solutions and dipping time except of FCR for hatched ducklings during the whole experimental period. Performance index recorded the best value of ducklings produced from eggs dipped into 10.0% glucose solution for 3 minutes (G5) than other interaction during the period of 1-21 days of age. No significant differences were recorded in relative weights of different carcass parts at hatch and 21 day of age except of liver at 21 day of age. Ducklings produced from eggs dipped into 10.0% glucose solution for 3 minutes (G5) recorded the best net return and economic efficiency than other interactions. It was concluded that dipping fertile Domyati duck eggs into 10.0% glucose solution for 3 minutes at the 24<sup>th</sup> day of incubation period could be used for improving hatchability, growth performance, net return and economic efficiency.
