Abstract
The study was conducted at the Poultry Station of the Regional Center for Food and Feed, Ministry of Agriculture, Egypt. The aim was to determine the effect of adding fennel seeds and dill seeds as feed additives to fattening diets.
A basic corn and soybean diet meeting all requirements recommended by the decision of the Ministry of Agriculture (1996) was fed to birds in the control and handler groups in the first week of life. Been fed on a from 1 to 22 days percentage of protein 22% and energy 3035.1 kcal/kg And The chicks were fed on rationale who 23 to 42 daysIt contains a percentage of protein19% andenergy3180kcal/kg.
The main results can be summarized as follows:
5.1.Chemical analysis of medicinal plants:
1. Proportion of dry matter, organic matter, crude protein, ether extract, crude fiber, ash and nitrogen-free extract (NFE) in Fennel seeds It was Straight. Moisture 9.90%, CP 11.35%, EE 3.93%, CF 22.5%, NFE 41.02%, and ash 10.96% on an air dry matter basis.
2. Proportion of dry matter, organic matter, crude protein, ether extract, crude fiber, ash and nitrogen-free extract (NFE) in seeds dill it was straight.
Moisture 10.30%, CP 18.00%, EE 2.33%, CF 20.7%, NFE 33.5%, and ash 16.50% on an air dry matter basis.
5.2.Growth performance:
1. At 3 weeks old, average viv.w LBW is minimally affected by FV and AG. While vivo weight increasedLBW significantly beforeFV and AG at the end of an experiment.
2. There are statistically significant differences in body weight on (LBWG) between treatments during 3-6 weeks of age. It was valuable for LBWG for group 4 feeding FV , and group 8 feedsAG. Both FV and AG increased body weight gain significantly. The level for FV of (0,0% - 2,0% - 0.4% - 0.6% - 0.8%) in the final diet (3-6a week )led to improvementLBWG. However, levels of AG ranged from 0.4% to 0.6% in the final diet (3–6a week) have no effect onLBWG.
3. Feed consumption during 3-6 weeks was significantly affected by fennel seeds and dill seeds as feed additives. However, there were slight differences in feed consumption for the whole experiment over the period due to the medicinal plants.
4. Feed conversion improved significantly (P < 0.05%). With FV. Best feed conversion value T5 (0.8% FV). Also use AG as a feed additive at level (0.0% -0.2% - 0.4% - 0.6% - 0.8%). Improves average feed conversion. but at the level of 0.6% (diet starter / finisher )AG, mean feed conversion (2.03 g) was lower than the other levels, but still better than the control group.
5. She wasn’t there deaths Refer to any of the experiments treatment or treatment.
5.3. Slaughter paths:
1. The percentages of carcass related to body weight deficiency were significantly increased with FV for experiment groups, while there was no significant effect due to AG.
2. There were significant effects of AG on giblets. While the effect on gizzard FV was not significant.
3. The percentage of heart weight increased significantly with the use of AG as a feed additive. FV had no effect on heart weight.
4. There was no significant effect of FV and AG on liver segments.
5. There is a significant effect of FV on the edible part. On the contrary, there was no significant effect of AG.
6. Seeds FV and AG significantly reduced the percentage of abdominal fat.
7. Use FV or AG Affected me pellets the blood white As effect As a feed additive, it significantly increases the weights of the spleen, follicle, and adrenal glandTimothy.
8. Use FV or AG As a feed additive, it significantly increases the weights of the spleen, follicle, and adrenal gland Timothy.
5.4. Blood plasma analysis:
1. There is no significant effect of using FV or AG as feed additive on total protein, albumin, and globulin and A/G ratio.
2. The total fat level decreased significantly with the additionfv. The use of AG as feed additives had no significant effect on total lipids.
3. The level of cholesterol in the blood plasma decreased by using FV
and AG.
4. It has been increased GOT, GPT were significantly increased by FV and AG as feed additives but their values remain in the normal range, so the use of FV or AG as feed additives has no harmful effect on liver function.
5.5. Immunological measurements
1. Use of FV or AG seeds as feed additives significantly increases the weights of spleen, bursa and thymus.
2- Injection of PHA-P into the toe web (in vivo cell-mediated immunoassay)
• After 24 hours of injection, it can be concluded that the chickens fed the diet with dill at a level of 0.6% and fennel at a level of 0.8% had a maximum swelling response to basal cutaneous hypersensitivity with little difference compared to the other traits and the control.
• Swelling response decreased by 48 and 72 hours. The dill group had a significantly higher skin swelling response at 48 hours compared to the control group.
3- Antibody response to sheep red blood cells (SRBCs)
• Total antibodies to SRBCs predicted that individuals fed the fennel groups had significantly over-responsive to SRBCs at 7 days post-secondary injection, whereas at 14 days post-secondary, the dill and fennel groups had significantly over-responsive to SRBCs.
• With regard to Immunoglobulin-M, the results showed that the fennel groups had a significantly over-responsive to SRBCs at 7 days post-secondary injection, while at 14 days post-secondary, the fennel group had a significantly over-responsive to SRBCs compared to the other groups.
• With regard to Immunoglobulin-G, the fennel group showed a significantly over-responsive to SRBCs at 7 days after the primary injection, while the dill group showed a significantly over-responsive to SRBCs at 7 and 14 days after the secondary injection.
5.6. Sensory Evaluation (Panel Test):
Both fennel seeds work FV and dill seeds AG It improves carcass color, taste, smell and consistency. It was the best level FV 0.8% and AG was 0.6% during the whole experiment.
5.7. Economic evaluation:
Relative Economic Efficiency (REE) is improved. for relationships Experimental from Medicinal plants. All diets containing medicinal plants performed better on REE than Control hanger.
The best values were for the two groups5 fennel and 8dillat levels (0.08% / 0.06%)(starter / finisher diet), respectively.
Conclusion:
Medicinal plants fennel seeds and dill seeds can be used as a feed additive in place of chemical compounds with no negative effects on producing birds.
from the results obtained in this study, it can be concluded that FV can be used in broiler feed at a ratio of 0.08% (starter/final feed), AG with a level of 0.06%. These levels improve weight gain, feed conversion, immunological performance, sensory evaluation, and economic efficiency.
