Effect of Propolis as Additive on Some Behavioural Patterns, Performance and Blood Parameters in Muscovy Broiler Ducks
Forty Muscovy ducklings of one day old were used in this study. They were brooded together for 3 weeks and then were randomly divided into two groups, 20 ducklings per each. Each group was housed in a well ventilated, previously cleaned, disinfected and well bedded with saw dust 3 x 3 m pen. Birds were maintained at 33 °C using gas heater and the temperature was gradually reduced by 3 °C / week until 21 °C was reached and then continued to the end of the experiment. Continuous lighting program with 23 hours light to one hour dark was maintained by the natural day light and a 60 watt bulb that placed centrally in each pen at 2 meters height above the heads of birds. Birds were daily fed ad-libitum on a commercial duck broiler starter ration up to 3 weeks of age and on a duck broiler grower finisher ration till 12 weeks old. The first group was fed on these diets without any supplements and used as a control group, however, the second one was fed the finisher rations provided and thoroughly mixed with ethanol extracted propolis at a rate of 2 gm / Kg of diet. Water was freely available allover the experiment. Behaviour, performance and blood parameters of the experimented birds were carried out. Obtained results indicated that use of propolis as a natural feed additive reflected on ducks with a reduction in stress behaviour, increased growth performance, increased immune response and resistance and improved welfare through improving the physical health state
Effect of Some Medicinal Plants as Feed Additives on Growth Performance, Blood Constituents and Carcass Characteristics of Broilers
The present work aimed to study the effect of feeding broiler chicks on diets containing different levels of fenugreek, anise and curcuma seeds powder, as natural feed additive on productive performance, carcass characteristics, some blood constituents and economic feed efficiency. One hundred and forty, one-day old (Ross 38) unsexed broiler chicks were obtained from local commercial source, weighed and randomly distributed to 7 equal groups, each of 20. The birds were fed with two basal diets (starter and finisher diets). The experimental diets were as follows: basal control diet without any feed additives (G1), basal diets supplemented with 0.2 and 0.5% fenugreek (G2 and G3 respectively), basal diets supplemented with 0.3 and 0.6% anise seeds (G4 and G5 respectively), and lastly basal diets supplemented with 0.3 and 0.5% curcuma (G6 and G7 respectively). During the experiment the body weight and feed intake were measured and consequently, weight gain and feed conversion ratio were calculated. At the end of the experiment, three birds from each group were slaughtered for blood sampling and serum extraction then. Finally, economical evaluation of the diets was calculated. The results showed that, dietary inclusion of fenugreek, anise and curcuma, had significant (P <0.05) improvement in the live body weight, total weight gain and feed conversion ratio, While, the feed intake was not affected by the dietary inclusion of them. Some blood constituents were affected with these additions. The relative economic feed efficiency was increased by dietary inclusion of the three additives
Effect of Feeding Probiotic on Performance of Broiler Ducks Fed Different Protein Levels
The present study was performed to investigate the effect of feeding Saccharomyces cerevisiae (probiotic) with different protein levels on duck performance, carcass traits and blood parameters. A total number of 40 two weeks old Molar ducklings randomly distributed into 4 equal groups.The first group was fed on control diet (16% CP) without any feed additives, while groups 2, 3 and 4 (T2, T3 and T4) were fed on basal diets containing 16, 14 and 12% CP respectively and supplemented with probiotic. Additives was probiotic, thepax (Saccharomyces cerevisiae), at 0.1% of the grower-finisher diet. The results showed that, birds fed on 16% protein diet supplemented with probiotic recorded significantly the best live body weight, body weight gain, feed intake and feed conversion compared with other treatments. There were no significant differences in hot carcass percentage, eviscerated percentage, dressing percentage and relative percentage of internal organs (gizzard, heart, liver and spleen), total protein and triglycerides, between different experimental groups. While there were significant (P<0.05) differences in serum albumin, globulin, cholesterol and uric acid between control group and other treatments. The relative economic feed efficiency was the highest in birds fed 16%protein diets supplemented with Saccharomyces cerevisiae compared with other treated groups. It could be concluded that, dietary inclusion of 0.1% S.cerevisiae in 16% protein diet improved body weight, weight gain, feed intake and feed conversion ratio and carcass traits
Effect of Feeding Propolis on Growth Performance of Broilers
An experiment was conducted to investigate the effect of propolis on broiler performance, carcass characteristics and blood parameters. The experiment was carried out with a completely randomized design of 4 treatments, supplemented with propolis at the rate of 0, 1, 2, and 3 mg/kg diet for 6 weeks. The results indicated that birds diet supplementation with propolis increased body weight (P<0.05), decreased feed intake and improved feed efficiency during the experiment. Carcass traits did not show significant differences for the treatments, with the exception of dressing percentage. The serum total protein and globulins were significantly (P<0.05) increased and the serum cholesterol and triglycerides were significantly (P<0.05) decreased in propolis supplemented broilers. No significant differences were observed in hematological parameters among the different groups. It could be concluded that dietary inclusion of propolis to poultry diets had a positive effect on growth performance and improved the immune response by elevating blood globulins level. Also, it decreases blood cholesterol and triglyceride levels.
 
Effect of Feeding Citric Acid on Performance of Broiler Ducks Fed Different Protein Levels
The present study was performed to investigate the effect of feeding citric acid with different protein levels on duck performance, carcass traits and blood parameters. A total number of 40 two weeks old Molar ducklings were randomly distributed into 4 equal groups, each of 10. The control diet was formulated to contain approximately crude protein (CP) (16%) and metabolizable energy (3000 kcal/kg diet) as recommended by NRC (1994). The first group was fed on control diet (16% CP) without any feed additives, while groups 2, 3 and 4 (T2, T3 and T4) were fed on basal diets containing 16, 14 and 12% CP respectively and supplemented with citric acid at 1.50% of the grower-finisher diet. The results showed that, birds fed on 16% protein diet supplemented with citric acid recorded significantly the best live body weight, body weight gain, feed intake and feed conversion compared with other treatments. There were no significant differences in hot carcass percentage, eviscerated percentage, dressing percentage and relative percentage of internal organs (gizzard, heart, liver and spleen) between different experimental groups. There were no significant differences in the level of serum total protein and triglycerides, while there were significant (P<0.05) differences in serum albumin, globulin, cholesterol and uric acid between control group and other treatments. There were no significant differences in the intestinal pH between different experimental groups. The relative economic feed efficiency was the highest in birds fed 16% protein diet supplemented with citric acid compared with other treated groups. It could be concluded that, dietary inclusion of 1.50 % citric acid in 16% protein diet improved body weight, weight gain, feed intake and feed conversion ratio and carcass traits

The Effect of Heat Stress on Blood Picture of Japanese Quail
This study aimed to evaluate the effect of heat stress on quail hematological parameters. A total number of 300 Japanese quail chicks (Coturnix Coturnix japonica) of 28 days old were exposed to different levels of raising temperatures (22, 29, 34, 36 and 40 ºC) for 15 days. At 42 days old, blood samples were collected from 14 birds (7 males + 7 females) that were randomly selected. The samples were used for determining red blood cells count, hemoglobin concentration, packed cell volume, total and differential white blood cells count, heterophils/ lymphocyte (H/L) ratio, mean corpuscular hemoglobin, mean corpuscular volume and mean corpuscular hemoglobin concentration. The obtained results indicated that, rearing quail birds under high environmental conditions during fattening period has a great adverse effect on these blood parameters
Effect of Dietary Supplemental Ginger on Broiler Performance, Carcass Characteristics and Blood Profile
A study using one hundred unsexed day-old broiler chicks (Ross 308), 25 birds/treatment was conducted to evaluate the effect of ginger powder as natural feed additives on the growth performance, carcass traits and blood parameters of broiler chickens. Four dietary treatments were formulated to meet the nutrient requirements of broiler chicks containing ginger powder at levels 0%, 0.2%, 0.4% and 0.6%. The results showed that no significant differences were recorded in body weight and body weight gainbetween different experimental groups. Birds fed diets supplemented with ginger exhibited better feed conversion (P>0.05) and lower feed intake than control birds. The measurements of carcass traits, hematological values and serum biochemical parameters showed no marked variation between the treated groups. It could be concluded that ginger powder at the used levels in this experiment has not potential to be used as a growth promoter in broiler chicks
