Effects of Dietary Turmeric and Hot Pepper Powder Supplementation on Productive Performance of Local Laying Hens

Abstract

The objective of this study was to investigate the effect of dietary supplementation with turmeric (TU), hot pepper (HP), or a combination of them as a powder on productive performance and functional properties of table eggs local strain (Sinai strain) hens at late production phase . A total number of 105 Sinai hens, 59-wks-old were weighed individually and randomly distributed equally into seven experimental treatments of three replicates each. The experimental design consists of the following groups; the first group was fed the basal diet without studied supplements and served as a control. The second and third groups were fed the basal diet supplemented with 0.1 and 0.25 % turmeric powder , respectively. The fourth and fifth groups were fed on the basal diet supplemented with 0.1 and 0.2 % hot pepper, respectively. The sixth and seventh groups were fed the basal diet with 0.1 % TU + 0.1 % HP or with 0.1 % TU + 0.2 % HP, respectively. The results obtained could be summarized as follows: hen fed diet supplemented with 0.1 % TU + 0.2 % HP recorded significantly the best values of egg number / hen, the second sate achieved for birds fed on diet with 0.2 % HP. Laying rate % improved significantly by adding a mixture of turmeric and hot pepper during all experimental period. Hens received diets plus turmeric at 0.1 and 0.25 % achieved the highest egg weight. Diets supplemented with mixture of TU + HP achieved the supreme effects on egg mass g / hen at all experimental periods. However, there were no significant effect on feed intake was due to adding TU or HP or both together. While , FCR values were clearly improved significantly with added turmeric + hot pepper (T6 and T7) compared to the control group. A significant improvement was found in shell thickness and Haugh unit as affected by diet with turmeric and pepper, nevertheless, shell and yolk index and percentage didn't show a statistical change during the experimental period between treatments. Hen groups received pepper 0.2 % alone or plus 0.1 % turmeric attained the highest economic efficiency compared the rest of hen groups. Conclusively, from the present study, it could be concluded that supplementing the elderly Sinai hen diets with turmeric, hot pepper or blender of both enhanced the bioavailability of turmeric also improved the liver functions as clearly exerted by enhancing egg production significantly especially, with 0.1 % TU + 0.2 % HP which improved reproduction performance, egg quality, FCR and EEF parameters during laying period.

Assessment of Production Performance and Egg Quality of Commercial Laying Hens Fed Black Pepper and Red Pepper Additives

“…In contrast, no significant difference was observed in feed conversion (feed/egg mass) between the treated groups and the control. Contrary to our findings, [18] reported a significant influence of red pepper on feed conversion ratio (feed/egg mass). Additionally, a mixture of red pepper and other phytogenic additives has also been reported to influence egg weight and mass positively in comparison with the non-supplemented control group [20], [24].…”

“…The control, however, shared statistical similarities with the other treated groups despite being the least. These findings are in agreement with other studies where dietary inclusion of phytogenic feed additives (fennel, black cumin and hot red pepper) led to significant (P < 0.05) differences in egg production [16]- [18]. However, some studies with red pepper contradict these findings and report a non-significant effect on egg-laying performance [19]- [21].…”

Impact of Dietary Supplementation of Grape Seed Powder as an Antioxidant on Growth Performance, Carcass Traits and Blood Constituents of Growing Female Rabbits Under Hot Climate in Egypt

“…In comparison to other dietary treatments (G2, G4, and G1), the serum concentrations of cholesterol and triglycerides were significantly lower in the G3 group of rabbits and significantly higher in the G2 and G3 groups in terms of total protein, albumin, and cholesterol. Consistent with the current findings, Azouz (2001) discovered that supplementing Hubbard broiler chicks' meals with fenugreek seeds led to a considerable increase in blood globulin and total protein. Globulins are carrier proteins for steroid and thyroid hormones and play a vital role in natural and acquired immunity to infection (Ganong, 2005).…”
