The experiment was extended from January 2019 to February 2019. The highest mean value was recorded for IR strain body weight at 7 days of age (172.4 ± 0.60, 172.2 ± 0.9 and 169.94 ± 0.99 g) in green, blue and white light, respectively. But for Cobb strain (169.42 ± 1.03, 167.22 ± 1.04 and 168.028 ± 0.83 g) in green, white and blue light, respectively. Where, body weight at 35 days of age was recorded for Cobb and IR strains at blue light (2002.17±12.81 g) and (2083.51±19.61 g), respectively, followed by white light (1985.22 g) and (2001.91±16.30 g), respectively, while green light registered the least value (1980.68 g) and (2001.82 ± 10.66 g), respectively. There were significant differences (P ≤ 0.05) in the values of growth hormone concentrations between control group (white light) and other two lights groups blue and green, on other hand, there were no significant differences in the values of growth hormone concentrations between Cobb and IR strains, the interaction between LED colors and strains was insignificant (P = 0.982).</strong>https://mjapfp.journals.ekb.eg/article_160908_9a582c3d5893d06e436d947b3eb2a03e.pdfMenoufia University, Faculty of AgricultureMenoufia Journal of Animal Poultry and Fish Production2357-08145320210301EFFECT OF SOME BIOLOGICAL AND NATURAL SUPPLEMENTATION ON RUMINANT PERFORMANCE555616120610.21608/mjapfp.2021.161206ENB.

However, the DCP% was not affected (P<0.05) by additives and its values ranged between 11.81 and 12.27%.</strong><strong> Animals fed enriched diets (Y, G and YG) showed higher ADG (180, 184 and 186 g/d, respectively) compared to control group (160g/d). Additives have no significant effect on feed intake either in the form of CFM or the roughage and consequently the total feed intake. All feed additives and their combination significantly (P<0.05) enhanced, with the same extent, the feed efficiency indicators of the enriched diets compared with control one. Yeast/garlic combined addition revealed the highest daily profit percentage relative to control (42%) followed by garlic (34.0%) and then yeast alone (31%) treatments. Energy utilization was significantly different (P<0.05) between the test groups where, the G group showed the highest values, but C group was the lowest values. When the combined additive (YG) was supplemented, N balance exhibited 15.2% increase above the control group. The concentration of blood immunoglobulins (IgA) and IgG differed (P <0.05) among groups being their concentration were enhanced by the respective additives. It could be concluded that using feed additive such as dry yeast (6 gm/h/d) or garlic powder (40 gm/h/d) or their combination (3gm plus 20 gm, respectively) in finishing diets of lamb tended to increase digestibility coefficients for most of nutrients, increasing nutritive value as TDN and appeared to increase the daily gain as well as enhanced the immune status of animals.</strong>https://mjapfp.journals.ekb.eg/article_161206_81c89cb2581200e902e5adf64e28e13f.pdfMenoufia University, Faculty of AgricultureMenoufia Journal of Animal Poultry and Fish Production2357-08145320210301RELATIONSHIP BETWEEN IMMUNE RESPONSE AND SOME REPRODUCTIVE HORMONES IN NORFA CHICKENS.575816369810.21608/mjapfp.2021.163698ENA.

The treatment (T1) was used as control with 200 mg/ ton diet sodium selenite. The results showed that application of nano-selenium in layer diets was effective in increasing egg number and egg mass. Also, nano-selenium improved some immunological traits, feed conversion and some egg quality traits. The optimum level of nano-selenium was 200 mg/ ton diet, which recorded 5.40 g feed/ g egg mass compared to 9.24 g feed/ g egg mass in control treatment (200 mg/ ton diet).

<strong>This study was conducted at the French Group Company at Al-Sadat City in Menoufia Governorate to investigate the effect of different pre-incubation egg storage period on the egg weight loss, hatchability, hatch window, duckling quality, duckling immunity, and its body weight. 384 fertile eggs were collected from 200 females of Pekin ducks (Anas platyrhynchos) at the age of (26 weeks of production), which mated by artificial insemention with 30 male of Muscovy ducks (Cairina moschata) to produce Molar ducks. Eggs were divided into four equal treatments (each of 96 eggs) and subjected to different storage periods (0, 4, 8 and 12 days) to determine the effects of different storage periods on egg weight loss, hatchability, hatch window, duckling quality, duckling immunity, and its body weight were measured for the different treatments. The results revealed that there were insignificantly differences (p ≤ 0.05) in egg weight loss by the different pre-incubation egg storage period. Storage eggs for 0 days had the highest hatchability percentage (92.2 %) compared to other experimental groups. Data demonstrated that storage eggs for 12 days achieved the largest hatch window (17:30 hours) when compared with 0, 4 and 8 days of storage. The relationship between storage period and duckling quality revealed that storage eggs for 0 days achieved the highest quality compared to the other groups. Immunity also, was affected by storage period (0 days was the hightest immunity) compared with the other groups. The effect of storage period on duckling body weight at age of one day was also studied. Data indicated that thrid group (storage periods 8 days) achieved significantly (P ≤ 0.01) highest body weight (76 g).</strong>
<strong>It could be concluded that storage of fertile duck eggs should not exceed 8 days to avoid excessive loss of egg water that impair the albumen contents which needed by the developing embryo for growth during incubation. The storage also, affected the transfer of maternal immunity to the embroyes and the hatched duklings. </strong>https://mjapfp.journals.ekb.eg/article_171241_17a4def018b75ee7063f30d4e1ecba0e.pdfMenoufia University, Faculty of AgricultureMenoufia Journal of Animal Poultry and Fish Production2357-08145320210301COMPARATIVE STUDY OF BROILER HYBRIDS PRODUCTIVE PERFORMANCE AT TALA TERRITORY – MENOUFIA GOVERNORATE THROUGH SEASONS OF THE YEAR.596017124410.21608/mjapfp.2021.171244ENM.
