The aim of this study was to investigate the effect of Tenebrio molitor meal (TM) and/or olive leaf powder (OL) supplementation to quail diet on animal performance, carcass yield and some blood parameters. One hundred and forty-four 1-day-old Japanese quails (body weight: 29.9 ± 0.46 g) were divided into four groups of 36 chicks, receiving four different diets, i.e., G1: Standard commercial (SCD); G2: SCD + 3% TM; G3: SCD + 3% OL; and G4: SCD + 3% TM + 2% OL. Feed and water were provided ad-libitum. The results showed that TM and OL inclusion promoted quail body weight at 5 weeks of age; p = 0.001. Feed conversion ratio (FCR) of G3 was significantly (p < 0.01) reduced compared to the other groups. Overall mortality was not different, at around 6.25%, between groups. Carcass [(71.5–74.3%)], gizzard [(2.5–2.7%)], heart [(1.1–1.2%)] and giblet [(6.8–6.9%)] yields were not influenced by the diet. No significant effect of the diet was observed for serum proteins, creatinine, urea and lipids. To conclude, the mixture of an incorporation of TM and OL in quail diet showed no adverse effects on growth performance, carcass constituent yields and serum constituents
Effect of feeding two-grain legumes, peas and faba beans, on egg quality and laying performances
(2020) Ait-Kaki, Asma; Deineko, T.; Moula, Nassim
Soymeal is now the main source of protein laying hens. This raw material is mainly produced abroad which makes Europe highly dependent on imports. A better protein autonomy could limit this economic impact and the environmental issue related to the cultivation of soybean. One of the options regularly studied over the past few decades to increase protein production in Europe is the cultivation of protein crops such as peas, faba beans and lupin. However, some inconvenient can limit their use in animal food as an alternative to soymeal, i.e., lower protein levels; presence of anti-nutritional factors; and non ideal amino acid profile. Therefore. te aim of this work was to assess the impact of using peas and faba beans as an alternative to soybean, on hens laying performances as well as on physical and nutritional eggs quality, including fatty acids profile. Two diets were tested, one containing only 22% of soymeal as proteins source (control group); and the second contains 45% of two leguminous plants (30% of peas and 15% faba beans) supplemented to 6% of soy meal. The egg-laying rate was significantly lower for the experimental group (51.79 vs. 60.63 %, p <0.05). However, no significant effect (P > 0.05) was found concerning physical (egg weight, weight, shell weight and weight, shell thickness and strength), and nutritional parameters (cholesterol and essential fatty acids).La harina de soja es ahora la principal fuente de gallinas ponedoras de proteínas. Esta materia prima se produce principalmente en el extranjero, lo que hace que Europa dependa en gran medida de las importaciones. Una mejor autonomía proteica podría limitar este impacto económico y la cuestión ambiental relacionada con el cultivo de soja. Una de las opciones estudiadas regularmente en las últimas décadas para aumentar la producción de proteínas en Europa es el cultivo de cultivos proteicos como guisantes, habas de faba y lupin. Sin embargo, algunos inconvenientes pueden limitar su uso en alimentos animales como alternativa a la harina de soja, es decir, niveles más bajos de proteínas; presencia de factores anti-nutricionales; y perfil de aminoácidos no ideal. por lo tanto. El objetivo de este trabajo era evaluar el impacto del uso de guisantes y frijoles faba como alternativa a la soja, en las prestaciones de puesta de gallinas, así como en la calidad de los huevos físicos y nutricionales, incluido el perfil de ácidos grasos. Se probaron dos dietas, una que contiene sólo el 22% de la harina de soja como fuente de proteínas (grupo de control); y la segunda contiene el 45% de dos plantas leguminosas (30% de guisantes y 15% de habas de faba) complementadas al 6% de la harina de soja. La tasa de puesta de huevos fue significativamente menor para el grupo experimental (51,79 frente a 60,63 %, p <0,05). Sin embargo, no se encontró ningún efecto significativo (P > 0,05) con respecto al físico (peso del huevo, peso, peso y peso de la cáscara, grosor y fuerza de la cáscara), y parámetros nutricionales (colesterol y ácidos grasos esenciales
Effect of olive leaf incorporation in animal feed on broiler turkey (Meleagris gallopavo) growth performance, welfare, oxidative status, and blood and biochemical serum parameters

This work investigates how incorporating olive leaves (OLs) (Olea europaea) into turkeys' (Meleagris gallopavo) diets affects their performance, welfare, blood biochemical parameters, and oxidative status of those reared in intensive farming conditions. The potential of this ingredient was assessed by comparing two dietary incorporation rates of olive leaves, 3 % and 6 %, in three commercial feeds corresponding to three growth phases over 15 weeks where feed was provided ad libitum. A total of 270 animals (broiler medium strain) were used. They were divided into three groups: the OL0, OL3, and OL6 regimens with OL incorporation rates of 0 %, 3 %, and 6 %, respectively. Animals were allocated to three pens of approximately 15 m2 of surface area; each pen had 30 animals, with a density of three turkeys per square meter. Throughout the rearing period, the diet had no effect on bird mortality. Olive leaves boosted growth rates. Indeed, after the experiment, the OL3 group had significantly higher weights than the OL6 and OL0 groups, which had the lowest feed conversion ratio. Furthermore, after bleeding, the weights and evisceration was significantly (p < 0.05) higher in the OL3 and OL0 groups compared to the OL6 group. However, OL0 turkeys had significantly higher spleen, heart, and abdominal fat weights than OL3 and OL6 turkeys. The three experimental groups had no significant differences (p>0.05) in carcass yield or gizzard or liver weights. OL supplementation improved oxidative status but had no effect on animal welfare or blood biochemical parameters, with the exception of the mean corpuscular hemoglobin concentration (MCHC), which was significantly (p < 0.05) lower in the OL3 group than in the OL0 and OL6 groups. Except for the mean cholesterol level, which was significantly (p < 0.05) lower in the OL3 and OL6 (1.29 g L−1) groups compared to the OL0 group, and the albumin level, which was higher in the OL0 group compared to the OL6 group, no significant effect was observed on biochemical serum parameters. Thus, a 3 % OL supplementation in the turkey diet appears promising for improving the bird's growth performance.
