<b>Black pepper (<i>Piper nigrum</i>) in diets for laying hens on performance, egg quality and blood biochemical parameters

Abstract

The objective of this study was to evaluate the increasing levels (0, 0.1, 0.2, 0.3, 0.4, 0.5 and 0.6%) of black pepper in diets for laying hens on performance, egg quality and blood biochemical parameters. Hissex White hens (n=168) at 30 weeks of age were used. The experimental method was completely randomized with seven treatments with four replicates of six birds each. Estimates of black pepper levels were determined by polynomial regression. The performance showed no significant differences (p > 0.05). The eggshell percentage was significantly influenced (p < 0.05), in which the level of 0.30% inclusion impaired eggshell quality. Triglycerides level increased significantly (p < 0.05), according to increasing levels of black pepper in the diet. It can be concluded that black pepper can be used in diets for laying hens as phytogenic additive without harming the performance. However, this inclusion causes a reduction in eggshell percentage and an increase in the level of triglycerides in the bloodstream.Pimenta do reino (Piper nigrum) na dieta de poedeiras leves sobre o desempenho, qualidade do ovo e análise bioquímica sanguínea RESUMO. Objetivou-se com este trabalho avaliar a inclusão de níveis crescentes (0; 0,1; 0,2; 0,3; 0,4; 0,5 e 0,6%) de pimenta do reino na dieta de poedeiras comercias leves sobre o desempenho, a qualidade do ovo e os parâmetros bioquímicos sanguíneos. Foram utilizadas 168 poedeiras da linhagem Hissex White com 30 semanas de idade. O delineamento experimental foi o inteiramente casualizado com sete tratamentos contendo quatro repetições de seis aves cada. As estimativas dos níveis de pimenta do reino foram determinadas por meio de regressão polinomial. As variáveis de desempenho produtivo não apresentaram diferenças significativas (p > 0,05). A percentagem de casca foi influenciada significativamente (p < 0,05) onde o nível de 0,30% de inclusão de pimenta do reino piorou a qualidade da casca dos ovos. A concentração de triglicerídeos apresentou diferenças significativas (p < 0,05) onde a inclusão de pimenta do reino ocasionou aumento crescente da concentração de triglicerídeos no sangue das aves. Concluiu-se que a pimenta do reino em dietas para poedeiras leves pode ser utilizada como aditivo fitogênico sem ocasionar alterações no desempenho produtivo. Todavia, com o advento desta inclusão, a pimenta do reino apresenta redução do percentual de casca do ovo e incremento na concentração de triglicerídeos na corrente sanguínea.Palavras-chave: alimento alternativo, casca do ovo, fitogênico, metabolismo sérico, piperina.

The Influences of Black Pepper, Turmeric and Fennel Essential Oils Supplementation in Feed on Egg Quality Characteristics of Layers

“…These findings are comparable to those of Liu et al (2020), who found that turmeric had a favorable effect on boosting HDL levels, and Elnaggar et al (2021), who reported that a combination diet of turmeric and black pepper produces better effects than either turmeric or black pepper individually. The effect of D1 (1 % black pepper) on TC or Total Cholesterol level is superior to Melo et al (2016) and Sidhu et al (2017). The results of the LDL levels indicated a substantial (p<0.05) decrease due to the incorporation of the D1 and D4 diet in the egg yolk are reported to be similar to those of Elnagger et al (2021).…”

“…The enhanced eggshell quality is due to increased laying bird feed intake, which releases serum calcium from plasma protein, allowing more Ca2+ from the blood to be involved in the production of eggshells, and our findings are superior to those of Liu et al (2020). Melo et al (2016), reported that black pepper improves egg quality, and our findings with black pepper inclusion were superior to their findings. In the current study, the egg shape index of laying hens fed with D1 (1 % black pepper) was greater than the other experimental groups, which is similar to Bugdayci et al (2018).…”

Effect of supplementing layer hen diet with phytogenic feed additives on laying performance, egg quality, egg lipid peroxidation and blood biochemical constituents

“…(2013) reported that dietary inclusion of black cumin seed at the levels of 10 to 15, 30 and 30 to 50 g/kg, respectively, increased egg weights. Furthermore, Melo et al. (2016) reported no significant differences in egg weight between control and black pepper supplemented groups.…”

Growth, Carcass Traits, Blood Hematology, Serum Metabolites, Immunity, and Oxidative Indices of Growing Rabbits Fed Diets Supplemented with Red or Black Pepper Oils

“…Interestingly, it was identified that piperine has massive advantages over other natural products: it produces no residues in the animal meat, increases cell recovery, and promotes anti-apoptotic and anti-oxidative activities. This suggests that piperine could be beneficial when used in the event of a compromised immune system, which is usually treated with antibiotics [19,20]. …”
