“…Efficient chili pepper active compounds are capsaicin, capsisin and capsantine. Chili pepper fruits are used by broiler and layer producers for increasing chicken appetite (Ozer et al, 2005), darkening the yolk color and improving laying performance (Ozer et al, 2006). Al-Kassie et al (2012) indicated that dietary inclusion of hot red pepper decreased the heterophil/lymphocytes (H/L) ratio, indicating its role in the immune system of birds.…”

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.

“…Red pepper fruits ( Capsicum annuum L.) are commonly eaten as vegetables and are an important source of spice (Özer et al., 2005). They are a good source of vitamins C and E (Palevitch and Craker, 1995; Daood et al., 1996), as well as provitamin A and carotenoid compounds, with well‐known antioxidant properties (Krinsky, 1994, 2001; Matsufuji et al., 1998).…”

“…(1986a,b) have reported that capsaicin enhanced the energy metabolism of rats through its beta‐adrenergic action and decreased perirenal adipose tissue weight. In chickens, 1% dietary red pepper caused faster development of ovaries (Özer et al., 2005), and capsaicin significantly increased intestinal mucus production (Jamroz et al., 2006). The small intestine is one of the most important sites of nutrient absorption.…”

To evaluate the effect of three kinds of red pepper supplementation 'Kagawa Hontaka' produced at Shiwaku Islands (KHS), Miki (KHM) and Takanotsume (TKT) on production performance, egg quality and intestinal histology in laying hens. A total of 32 laying hens (39 weeks of age) were randomly allotted to four groups, each comprising eight hens. Birds were fed a basal diet supplemented with red pepper at 0% (control), 0.5% KHS, 0.5% KHM and 0.5% TKT, respectively. Compared with the control group, no significant difference (p > 0.05) in feed consumption, final body weight, hen-day production, egg mass, feed efficiency, shell-breaking strength, shell thickness, shell ratio, albumen ratio, yolk ratio and Haugh units was observed among the experimental groups. Roche yolk colour fan (RYCF) value increased significantly in all experimental groups (p < 0.05). Furthermore, the KHS and KHM groups showed higher RYCF values than the TKT group (p < 0.05). Spectrophotometric measurements of yolk colour, redness (a*) and yellow index (YI) values were higher in the KHS and KHM groups (p < 0.0001). The yellowness (b*) value was lower in the TKT group (p < 0.05). The lightness (L*) value was lower in the KHS and KHM groups (p < 0.05). Villus height, villus area, cell area and cell mitosis in all intestinal segments tended to be higher in all experimental groups. Jejunal cell area and cell mitosis were higher in experimental groups than in the control group (p < 0.05). The cells on the villus tip surface were protuberated in all experimental groups. In conclusion, the KHS, KHM and TKT groups showed hypertrophied intestinal villi and epithelial cell functions. These results indicate that dietary red pepper has stimulating effect on intestinal villi and the structure of epithelial cells, and the 0.5% KHS and KHM groups improved in egg yolk colour.

“…Physiologically, foods such as those containing capsaicin have been found to influence metabolism or homeostasis, sometimes resulting in clinically important effects on animal gastrointestinal, cardiovascular and respiratory systems [7,19]. Human studies have demonstrated that red pepper consumption decreases appetite while it increases satiety [26], as well as energy expenditure [28], which is thought to be mediated by increased activity of sympathetic nervous system by capsaicin [25].…”
