as lycopene and allicin extracts in growing chicks’ diets. Chicks for
group 1 were feed basal diet and served as a control, chicks of second
group were fed basal diet supplemented with 150 mg V.E/ kg, chicks
of 3rd, 4th, 5th, 6th
, 7
th
, and 8th groups were fed basal diets
supplemented with 100, 200 and 300 mg lycopene or allicin/kg of
diet, respectively. The results showed that the improvement of feed
conversion ratio had been realized for chicks of T7 group compared
with the other rest groups. Plasma total cholesterol value in addition to
intestinal counts of total aerobic and anaerobic bacterial and total
coliform were significantly decreased for all experimental groups of
supplementation extracts and concentrations compared with control.
The greatest reduction of bacterial count was observed in the intestinal
chicks fed 300 mg of allicin/kg diet (T8) compared with the others. In
conclusion, using extracts of lycopene and allicin for cocks' diet could
be recommended for realizing the best results of growth performance
and antibacterial influence.

Two hundred and fourty Hubbard broiler chicks at three weeks of age were used in this study. Chicks were weighed and randomly distributed into sixteen treatments, with three replicates (5 chicks of each), The Experiment was terminated when birds were 7 weeks old. Weight gain, feed intake, feed conversion and some blood serum constituents were measured. At the end of the experiment digestibility values and carcass characteristi...

A total of 243 Gimmizah layer hen and 27 cocks aged 24 weeks were randomly distributed to nine dietary treatments in (3 x 3) factorial arrangement with 3 levels of Lys (0.527, 0.586 and 0.677 % of diet) and 3 levels of Met (0.380, 0.451 and 0.489 % of diet). Results indicated that, Gimmizah layer hen fed diets supplemented with 0.380 % Met regardless of Lys % significantly increased egg production percentage (EP) and egg mass (EM) as compared with all other dietary treatments. The highest EP and EM were recorded for layer hen fed 0.380% Met and 0.677% Lys with the ratio 0.97 of total sulphur amino acids (TSAA) and Lys. Supplementation Gimmizah layer hen diet with different levels of Met and Lys insignificantly affected on the amount of feed intake (FI) among different treatments, while, feed c...

Different levels of Ch.F (0, 0.125, 0.25, 0.5 and 1.0%) were used to study their affects on some blood parameters, intestinal total bacterial count and histomorphology of growing rabbits. Sixty cross-breed male rabbits (New Zealand white X Black Baladi) at 6 weeks of age with an average 572 g live body weight were used. Rabbits were randomly distributed to 5 treatments (12 animals per each). The results could be summarized as the following: Total protein, albumin, globulin, triglycerides and urea significantly increased by increasing the level of Ch.F in the experimental diets compared with the control group. Raising the level of Ch.F from 0.125 to 1.0 % significantly increased PCV %. The different levels of Ch.F in rabbits diet had no significant effect on differential leukocyte counts. Addition of Ch.F had a great value for reduction of the microbial load in intestine. ...

Two hundred and sixteen chicks were used for each experimental amino acid during 2-6, 7-12 and 13-18 wks of age. Chicks were distributed into six treatments and replicated three times. The six graded levels of Met for first experiment were 0.26, 0.30, 0.34, 0.38, 0.42 and 0.46%, during 2-6 and 7-12 wks of age and 0.21, 0.26, 0.32, 0.38, 0.44, and 0.50%, during 13-18 wks of age, while Lys was constant ( 0.99% ) during the mentioned experimental periods. The six graded levels of Lys ( second experiment ) during 2-6 wks of age were 0.65, 0.70, 0.75, 0.80, 0.85 and 0.90%, also during 7-12 wks of age were 0.50, 0.60, 0.70, 0.80, 0.90 and 1.00 %, besides during 13-18 wks of age Lys levels were 0.45, 0.55, 0.67, 0.78, 0.89 and 1.00%, while Met levels were 0.46%, 0.47% and 0.50% during the same pervious mentioned perio...

A total of 150 male Gimmizah local strain chicks (4 weeks of age) were randomly distributed among five treatment groups in battery brooder placed in a temperature-controlled room until 14 weeks of age. The first treatment was fed the basal diet only without any supplementation and kept in the first sector under optimum temperature 22-24 o C and relative humidity (RH) 45-55 % (normal) used as negative control. Whereas, the other four treatments were kept in the last sector under chronic heat stress condition (38°C±1; 55-65 % RH) for three successive days a week from 11.00 am until 15.00 pm. The first heat stress group was fed the basal diet only without any supplementation and used as positive control (PC). Whereas in the other three treatments were fed the basal diet supplemented with Spirulina platensis at levels (0.5 and 1 g/kg diet) and vitamin E (75 mg/kg diet). The results indicated that different supplementations as Spirulina and VE decreased adverse effect of heat stress on growth performance and blood total protein, albumin, globulin, createinin, ALT, AST, total lipids, LDL, WBCs, RBCs, immunity of Chickens. In conclusion, addition of Spirulina platensis improved growth performance, immunity and can be decreased adverse effect stress on chickens under heat stress condition.

The first group was fed on a basal diet while the 2, 3,4 and 5 groups were fed on diets contained 0.125, 0.25, 0.5 and 1.0% chamomile flowers (Ch.F), respectively. The results could be summarized as the following: The beast feed conversion ratio recorded with rabbits fed diet containing 0.25% Ch.F. Incorporation of Ch.F in rabbit diet improved digestibility coefficient values, blood biochemical parameters. Addition of Ch.F had a great value for reduction the microbial load in intestine. Also, Ch.F has a powerful effect on enterobacteriaceas colonization in different part of small intestine and has the capability to reduce much of pathogenic
strains. From the present results it can be recommended that the best level that should be applied from the Ch.F as natural growth promoter and economical efficiency is 2.5
kg / ton diet.
