Seven tilapia hybrid fingerlings treatments (45 fingerlings each, as average initial body weight 3.03±0.01g) were used at period 90 days in closed system. Seven dietary approximately iso-nitrogenous (30.63±0.33 % crude protein) and iso-caloric (4757 ± 39 kcal GE/ kg diet) were formulated, fed to three aquaria for each treatment (diet). Medicinal herbs additives of three levels from marjoram (Majorana hortensis) or sage (Salvia officinalis L.) being 150, 300 and 600 mg/kg diet, respectively. The obtained results revealed that fish groups fed the low levels (150 mg/ Kg) of either marjoram or sage showed high response in final body weight, total weight gain, SGR (%/day) and RGR (%), followed  by the moderate levels (300 mg/ Kg) and finally the high levels of  the additives (600 mg/ Kg) compared to fish fed the control diet. Also, it is noted that herbal plant improve in feed utilization parameters of tilapia hybrid fingerlings, but it was declined when the level of herbal plant increased.  Fish groups fed diets containing sage reflected high values of fat productive values (%) in the low level of additives and declined with increasing the level of sage in the diet. On the other hand, fish groups fed marjoram showed that declined FPV (%) with increasing the level of the marjoram used. Therefore, it could be concluded that tilapia hybrid (Oreochromis niloticus × Oreochromis aureus) fingerlings achieve increasing by 150 and 300mg/ kg dietary addition of marjoram or sage herbs, respectively.   }, keywords = {Nile tilapia hybrid,Medicinal Herbs,marjoram,Sage,Growth performance,feed utilization}, url = {https://jappmu.journals.ekb.eg/article_82781.html}, eprint = {https://jappmu.journals.ekb.eg/article_82781_49574413e338ea75bf07cb0618f12f64.pdf} } @article { author = {Motawe,, H. and El Shinnawy, A. and El-Afifi, T. and Hashem, N. and Abu Zaid, Abeer}, title = {UTILIZATION OF OKARA MEAL AS A SOURCE OF PLANT PROTEIN IN BROILER DIETS.}, journal = {Journal of Animal and Poultry Production}, volume = {3}, number = {3}, pages = {127-136}, year = {2012}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3642}, eissn = {2090-3723}, doi = {10.21608/jappmu.2012.82782}, abstract = {This experiment was conducted to evaluate the effects of partial or complete replacement of okara meal for soybean meal on broiler performance, nutrients digestibility and economic efficiency. A total number of 350 one-day-old unsexed Ross chicks of nearly similar live body weight (45 g.) were randomly divided into equal five treatments; each contained 70 birds in seven replicates of ten birds each. Five experimental diets were formulated to be approximately iso-caloric and iso- nitrogenous according to the management recommendation guide data (Ross). Birds were fed starter- growers (1-4 weeks) and finisher (5-7 weeks) diets ad lib and had free access to water for the entire experimental period. The results showed that the whole experimental period, feeding graded levels of okara meal replacing for soybean meal at levels of either 25,50 and 75 % in broiler diets had no significant   effect on live body weight gain (BWG), feed conversion rate (FCR) and average live body weight (LBW) compared with control group. However, the differences were significant poorest (P<0.05) as replacing okara meal for soybean meal at a level of 100% compared to control group or other treatments. There were significant decreases (P<0.05) feed intake values due to using different levels of okara meal compared to control group. Results showed a significant increase (P<0.05)in average values of EE and CF digestibility  and N retention with using okara meal as replacing for soybean meal at levels of 25,50 and 75% while, the use of high level (100%) significantly decreased most of nutrient digestibility coefficient and nitrogen's balance. The obtained results showed that replacing of soybean meal by okara that replacing soybean meal by okara meal in broiler diets up to level of 75% can reduce cost of feeding, save a considerable amounts of expensive ingredients and meal at levels of 25, 50 and 75% in broiler diets had no significant effect on carcass traits of chicks, while full replacement had a significant adverse effect.

Five hundred seventy-six Hubbard broiler chicks were randomly divided into 16 equal experimental groups; each contained 3 equal replications. The chicks were kept in brooding and growing batteries during the starter and finisher periods, 0-3 and 3-7 weeks of age. Sixteen starter and finisher experimental diets were formulated and used. Each experimental group was given its respective diet and all birds were managed similarly and had free access to feed and water. The results obtained can be summarized in the following:      Apart from the effect of diet form (DF) or enzyme addition (EA), feeding CWC-diets had no adverse effect on live body weight (LBW) or body weight gain (BWG) of broilers during the entire experimental period. When the dietary CWC level reached 45% feed intake (FI) of broilers was significantly increased while feed conversion (FC) was negatively affected compared with their control counterparts. Birds fed pellets exhibited significantly better LBW and BWG than those of birds fed the mash diets, while FI and FC were not affected, regardless of the effect of dietary CWC level or EA. Similarly, LBW and BWG of broilers were positively affected due to dietary EA as compared to those of birds fed the un-supplemented diets, irrespective of the effect of DF or dietary CWC level. Increasing dietary CWC level to 30 or 45% adversely affected digestibilities dry matter, organic matter and crude protein and rate of nitrogen retention. Birds fed the pelleted diets had better digestibilities for crude protein and ether extract and nitrogen retention compared with those fed the mash diets. Dietary EA  led to an increase in the rate of nitrogen retention. Carcass traits of broilers were not significantly affected by dietary CWC level with the exception of significant reductions in dressing-out and abdominal fat percentages and an increase in relative weight of gizzard for birds fed the 45% CWC-diets compared with the controls. Dietary EA and DF had no effect on carcass traits, except that gizzard percent slightly  reduced due to feeding pellets as compared to feeding the mash diets. There were significant  reductions in serum levels of triglycerides, total cholesterol, and LDL-cholesterol for broilers fed the CWC-containing diets, particularly having the 45%level. However, blood parameters were not affected by EA or DF, with the exception of a significant decrease in triglycerides level in broilers fed pellets as compared to those fed the mash diets. Economic efficiency of broiler production was not affected by including CWC up to 30% in their diets; pelleting of diets and enzyme addition might have a beneficial effect. It could be concluded that corn-with-cobs meal can be included up to 30% in diets of broilers without adverse effects on broiler performance; pelleting of diets and enzyme addition had positive effects in this respect.}, keywords = {Corn-with-cobs meal,Pelleting,Sicozyme,broiler performance,carcass traits,blood constituents,nutrients digestibility,economic efficiency}, url = {https://jappmu.journals.ekb.eg/article_82783.html}, eprint = {https://jappmu.journals.ekb.eg/article_82783_12c2d1ba35de240ef8ad736f944a0039.pdf} } @article { author = {El-Serwy, Amina and Elwardany, I. and Ibrahim, A.}, title = {EFFECT OF DIETARY SUPPLEMENTAL AMINO ACIDS WITH OR WITHOUT PROBIOTIC ON PRODUCTIVE PERFORMANCE OF BROILER CHICKS}, journal = {Journal of Animal and Poultry Production}, volume = {3}, number = {3}, pages = {157-166}, year = {2012}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3642}, eissn = {2090-3723}, doi = {10.21608/jappmu.2012.82784}, abstract = {Three hundred and sixty, 2 weeks old, unsexed Cobb chicks were used in this study to evaluate the effect of low protein diets fortification with amino acids and Probiotic on productive performance, carcass traits and some blood constituents.
