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.

“…This result is corroborated by other studies. Nogueira et al (2014) evaluated the inclusion of different levels of palm oil in the feed of laying hens and concluded that plant-derived lipid sources did not affect production variables even as Faitarone et al (2016) studied 33-week-old laying hens of the Lohmann LSL lineage and concluded that the inclusion of canola, soybean, and linseed oil in the feed did not significantly affect production performance, emphasizing that soybean oil can be replaced by other vegetable sources of oil. In our study, SC and CC using CCOHA did not significantly affect EWL, LP, FCDZ, and FCEM (p>0.05).…”

The objective of this study was to evaluate egg production and quality after including crude corn oil with high acidity (CCOHA) in the feed of laying hens. The design was completely randomized to three treatments and six replicates each. The sample included 90 hens of the Lohmann LSL lineage, housed in cages; each cage contained five animals and constituted an experimental unit. The evaluated feeds were corn-based feed with degummed soybean oil (CSO), corn-based feed with CCOHA (CC) and sorghum-based feed with CCOHA (SC). At the end of the 28-day cycle, the following productivity parameters were evaluated: egg weight at laying (EWL), laying percentage (LP), feed conversion per dozen eggs (FCDZ) and feed conversion per egg mass (FCEM). The evaluated internal and external quality parameters of the eggs were yolk percentage (YP), yolk index (YI), and yolk pH (YpH); albumen percentage (AP), albumen index (AI), and albumen pH (ApH); percentage shell (PS) and shell surface area (SSA); Haugh unit (HU) and egg yolk color (EYC). There were no significant differences in EW, LP, FCDZ, and FCEM between the experimental feeds. Moreover, the use of crude corn oil with high acidity in laying hens rations did not influence the parameters of YP, YI, YpH, AP, AI, ApH, PS, SSA, HU, and EYC.

“…Faitarone et al (2013) also commented that the high inclusion of oil in hens' diets cause a significant reduction on the feed intake, attributing this result to high percentages of long-chains of polyunsaturated fatty acids in fish oil that transfer their sensory characteristics to the diets, changing their palatability (Ayed et al, 2015). Normally, oils of animal origin, such as fish oil, tend to cause a larger effect in feed intake than oils of vegetal origin (Bertipaglia et al, 2016;Silva et al, 2017), attributing this effect to peculiar odor and flavor that these by-products transfer to the diets from their polyunsaturated fatty acids (Freitas et al, 2013, Nogueira et al, 2014.…”

The present study aimed to evaluate increasing levels of fish waste oil in laying hens diets on performance, egg quality, and sensory features of the eggs. 192 Hisex White laying hens with 29 weeks of age were used, with water and food ad libitum. The experimental design was completely randomized consisting of eight treatments corresponding to the inclusion levels of fish waste oil (0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 and 3.5%) in the diets, with four replicates of six birds each. Data collected were subjected to polynomial regression at 5% of significance. Differences (p<0.05) were observed in feed intake and egg mass. Feed intake increased until 2.50% of fish waste oil in the diets. Differences were not observed (p>0.05) in all variables analyzed. Differences were observed (p<0.05) in flavor. Eggs from birds fed diets up to 2.00% present better acceptance by the tasters. Above this level, there was a considerable drop in acceptance. From these results, the present study indicates that the use of fish waste oilin laying hens diets did not affect the egg quality. However, its high inclusion negatively affected the feed intake, egg mass, and egg flavor.
