Simple Summary: This study evaluated the effect of dietary supplementation with organic silicon on the growth performance, blood biochemistry, digestive enzymes, morphohistology, intestinal microbiota and stress resistance in juvenile hybrid Tilapia (Oreochromis mossambicus × Oreochromis niloticus). It is concluded that organic silicon had no negative effects on the physiology and metabolism of the fish. The results showed that up to 50 mg·kg
−1 of organic silicon can be applied to the diet of red Tilapia, improving digestive, metabolic and growth performance. The interactions between zootechnical performance, physiological digestive and metabolic capacity in hybrid red Tilapia still deserve further exploration. In recent decades, interest has been aroused worldwide in the use of silicon in nutrition; however, information on its effect on nutrition and metabolism of fish is limited. The objective of the research was to evaluate the effect of dietary supplementation with organic silicon on the growth performance, blood biochemistry, digestive enzymes, morphohistology and intestinal microbiota and stress resistance in hybrid Tilapia (Oreochromis mossambicus × Oreochromis niloticus). Methodologically, six levels of organic silicon (DOS) [control (0), 10, 20, 30, 40 and 50 mg·kg−1 ] were used to feed juvenile fish (initial weight 7.51 ± 0.25 g) grown for eight weeks in 18 aquariums (15 fish/aquarium). The results indicated that growth performance showed differences (p < 0.05) for specific growth rate, feed conversion and survival. Triglycerides, cholesterol and glucose, transaminases and digestive enzymes were significantly influenced by DOS levels. The histological study confirmed that the administered diets did not cause damage and induced significant morphological changes in the proximal intestine. The 16S rRNA gene sequencing analysis of the gut microbiota showed a high diversity and richness of OTU/Chao-1, with Fusobacteria, Proteobacteria, Bacteroidetes and Acidobacteria predominating in the DOS treatments compared to the control (p < 0.05). Induction of hypoxia stress after the feeding period showed a significant relative survival rate of 83.33% in fish fed 50 mg·kg−1 . It is concluded that the DOS treatments performed better than the control treatment in most of the variables analysed. DOS had no negative effects on the fish. The results showed that up to 50 mg·kg−1 DOS improved digestive, metabolic and growth performance in hybrid Tilapia. [ABSTRACT FROM AUTHOR]- Published

Objective. To determine the response of the productive indicators when including palm (Elaeis guineensis) kernel cake (PKC) in diets for the nutrition of tilapia fry (Oreochromis niloticus). Material and methods. Three hundred sex-reversed males of tilapia (4.89 ± 0.09 g) were used and distributed according to a completely random design for 60 days, in three replicates per treatment (20 fish per replicate). The PKC was used to formulate five diets isoproteic (30.64%), isolipidics (7.38%) and isoenergetic (11.84 MJ kg-1 of feed), control (T0), 5% (T5); 10% (T10); 15% (T15), and 20% (T20). Results. Fish fed T0, T5, and T10 treatments did not show statistical differences among groups (p>0.05), but yes with the T15 and T20 in the overall nutrient digestibility, growth, and body composition. However, the inclusion of up to 20% PKC in the diet decreased the feed cost.

Objective. Characterizing the chemical composition of pre-dried chicken intestines with vegetable meal (VM), as an alternative source of protein for aquaculture. Materials and methods. Chicken intestines, grounded, cooked and defatted (CIGCD), were mixed individually with VM: rice powder (RP), wheat bran (WB), palm kernel cake (PKC), cornmeal (CM) and soybean meal (SBM), in proportions (w:w): 80:20, 70:30, 60:40, 50:50 and 40:60 (CIGCD:VM), for a total of 20 experimental treatments, according to a completely randomized design. Dry matter, crude protein, lipid, fiber, ashes, gross energy (MJ kg-1) and costs were evaluated. The principal component analysis (PCA) was applied to verify the interaction between proportions. Results. The proportions with higher levels of CIGCD, protein and lipid content increased (p<0.05), with reduced cost (p<0.05). Those with higher values of VM, fiber and ash showed high values (p<0.05). The mixtures with SBM, high figures of protein, energy and costs (p<0.05) and with PKC the lowest costs (p<0.05). Conclusions. The proportions of CIGCD:VM reached high levels of dry matter, which facilitated the dehydration process. The content of protein, lipid, energy and costs, obtained in the different mixtures, accredits them as possible aquaculture feed, to replace conventional protein in diets, according to the species, productive purpose and market requirements. The PCA with covariance matrix suggests that the mixtures CIGCD:VM, the treatments CIGCD:SBM (80:20), CIGCD:SBM (70:30) and CIGCD:SBM (60:40) have better nutritional characteristics, although, the CIGCD:PKC (80:20) ratio showed high protein levels and was the most economical.

- Abstract
To evaluate the chemical composition of the earthworm (Eisenia foetida) co-dried (EW) with vegetable meals (VM) as animal feed ingredient, the blends were mixed with wheat bran (WB), rice powder (RP), corn meal (CM) and soy cake meal (SCM) in proportions of 85:15; 75:25 and 65:35. The dry matter (DM), crude protein (CP), crude fat (CFA), crude fiber (CF), ashes and nitrogen-free extract (NFE) of the ingredients and final mixtures were determined. All the mixtures resulted with a high content of DM (≥90.00 %). No significant differences among the proportions were revealed (P>0.05). In addition, the higher inclusion of the earthworm in the proportions (85:15) increased (P<0.05) the CP (54.70 %), CFA (7.28 %), and ashes (10.20 %), mainly when mixed with SCM, CM, and RP, respectively. However, the use of vegetable meals proportionally increased the CF (7.31 %), and NFE (52.62 %), mainly with the proportion of 65:35 and with RP and CM, respectively (P<0.05). The results showed that the vegetable meals (WB, RP, CM, and SCM) are useful to co-dry the earthworm to be use for animal feed. It is concluded that the most appropriate proportion (VM:EW) will depend on the animal species, productive stage and market requirement., Para evaluar la composición química de la lombriz de tierra (Eisenia foetida) (LT) presecada con harinas vegetales (HV) como alimento animal, las mezclas se secaron individualmente y se elaboraron distintas premezclas con salvado de trigo (ST), polvo de arroz (PA), harina de maíz (HM) y harina de pasta de soya (HPS) en proporciones de 85:15; 75:25 y 65:35. Se determinó la materia seca (MS), proteína cruda (PC), grasa cruda (GC), fibra cruda (FC), cenizas y extracto libre de nitrógeno (ELN) de los ingredientes y de las mezclas finales. Todas las mezclas mostraron un alto contenido de MS (≥90.00 %). No se revelaron diferencias significativas entre las proporciones (P>0.05). La mayor inclusión de la lombriz de tierra en las proporciones (85:15) incrementó (P<0.05) la PC, GC y cenizas, principalmente cuando se mezcló con la harina de soya, harina de maíz y polvo de arroz, respectivamente. Sin embargo, el uso de las harinas vegetales incrementó proporcionalmente la FC (7,31 %) y el ELN (52.62 %), especialmente con la proporción de 65:35 y con PA y HM, respectivamente (P<0.05). Los resultados mostraron que las harinas de vegetales (WB, RP, CM y SCM) son útiles para presecar la lombriz de tierra para uso en la alimentación animal. Se concluye que la proporción más adecuada (VM:EW) dependerá de las especies animales, la etapa productiva y los requisitos del mercado.

- Abstract
The ensilability and chemical composition of silages made with different proportions (100:0; 90:10; 80:20; 70:30; 60:40 and 50:50%) of foliage (fresh and pre-wilted) and noni fruit (fresh) was evaluated. Some fermentative patterns of the original forages and the chemical content of the silages were determined. Correlations between the parameters of quality, chemical composition and the fruit levels in the mixture were made and adjusted the same one to polynomial equations. A higher inclusion of fruits with both fresh and pre-wilted foliage of noni decreases the pH and NH3-N Nt-1 in the silage. In addition, the increase in the level of fruit increased the concentration of water soluble carbohydrates (WSC) and the ratio of WSC/PC. Moreover, the pre-wilted foliage increased the dry matter (DM) content and its combination with fruit levels between 30 to 40% decreased the fibrous compounds and crude protein (CP) concentration in the silage. According to a cubic model used, the pre-wilted foliage and fruit proportions showed a higher R2 for DM, neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent-lignin (ADL) and cellulose, while CP and hemicelluloses were higher in the fresh plant material. The results showed that the pre-withered process (foliage) and inclusion levels of 30 and 40% of fruits in the mixture improved the quality of the silage intended for animals., Se evaluó la ensilabilidad y la composición química de ensilajes elaborados con diferentes proporciones (100: 0; 90:10; 80:20; 70:30; 60:40 y 50: 50%) de follaje (fresco y presecado) y la fruta de noni (fresca). Se determinaron algunos patrones de fermentación de los forrajes originales y el contenido químico de los ensilajes. Se hicieron correlaciones entre los parámetros de calidad, la composición química y los niveles de fruta en la mezcla y se ajustaron a ecuaciones polinomiales. Una mayor inclusión de frutas con follaje fresco y pre-secado de noni, disminuyó el pH y el NH3-N Nt-1 en el ensilaje. Además, en incremento en el nivel de fruta aumentó la concentración de carbohidratos solubles en agua (CSA) y la relación de CSA/PB. También, el follaje pre-secado aumentó el contenido de materia seca (MS) y su combinación con niveles de fruta entre 30 a 40%, disminuyó los compuestos fibrosos y la concentración de proteína bruta (PB) en el ensilaje. Según un modelo cúbico utilizado, las proporciones de follaje y frutos previamente presecado, mostraron un R2 mayor para MS, fibra detergente neutra (FDN), fibra detergente ácida (FDA), lignina ácido detergente (LAD) y celulosa, mientras que PB y hemicelulosa, fueron superiores en el material vegetal fresco. Los resultados mostraron que el proceso pre-secado (follaje) y los niveles de inclusión de 30 y 40% de las frutas en la mezcla, mejoraron la calidad del ensilaje destinado a los animales.
