Apparent Digestibility Coefficients of Nutrients and Energy from Animal-Origin Proteins for Macrobrachium rosenbergii Juveniles Rosane Lopes Ferreira, Cecília de Souza Valente, Lilian Carolina Rosa Silva, Nathã Costa de Sousa, Marlise Teresinha Mauerwerk, et al. Fishes, 2024 In prawn farming, the main protein source used in aquafeed formulations is fishmeal. Nevertheless, one estimates that in the coming years, this protein source will no longer be able to meet the demand for the activity. The search for new ingredients is important to meet the increasing demand and minimize environmental impacts, such as the reduction in fish stocks and the eutrophication of aquatic systems. The objective of this study was to determine the apparent digestibility coefficients of dry matter (DM), crude protein (CP), gross energy (GE), and ether extract (EE) of fishmeal, poultry co-products (viscera and hydrolysed feather), and insect meal (Gromphadorhina portentosa) for giant river prawn (Macrobrachium rosenbergii) juveniles. To determine the apparent digestibility coefficients (ADCs), 90 prawns (average weight, 15 g) were randomly distributed among three experimental units. The reference feed was formulated according to the requirements of the giant river prawn, with 35% crude protein and a gross energy of 3600 kcal kg−1. The test diets comprised 70% of the reference diet and 30% of the respective test ingredients. Prawns were fed three times a day until apparent satiety. Faeces were collected using the indirect siphoning method, twice a day at the same feeding site (at 7:30 a.m. and 6:30 p.m.). The water parameters were temperature (27 °C), dissolved oxygen (6.65 mg L−1) and pH (7.76). The ACDs of DM, CP, EE, and GE were, respectively, 61.48; 88.28; 99.89 and 88.25 for fishmeal; 76.48; 81.55; 97.29 and 85.13 for poultry viscera meal; 73.82; 75.21; 73.17 and 76.42 for hydrolysed feather meal; and 52.35; 59,48; 87.95 and 67.64 for G. portentosa meal. The values of protein (%) and digestible energy (kcal kg−1) were 55.20 and 3711 for fishmeal; 47.27 and 4285 for poultry viscera’s meal; 65.03 and 4145 for hydrolysed feather meal; and 47.72 and 3616 for G. portentosa meal. These results showed the potential use of insect meals and poultry co-products as ingredients for the diets of M. rosenbergii juveniles, as they present digestible values close to those found for fishmeal, the main raw material used in aquaculture diets.
Dietary supplementation with fumaric acid improves growth performance in nile tilapia juveniles Suzane C. V. das Neves, Suzianny M. B. C. da Silva, Gisely K. A. Costa, Eudes S. Correia, Alexandre L. Santos, et al. Animals, 2022 Organic acids have recently been identified as promising replacements for antibiotics in aquafeeds that promote fish growth and feed efficiency. This study evaluated the inclusion of fumaric acid (FA; 0, 5, 10, 15, 20, and 30 g/kg) in diets (350 g/kg CP; 3.4 kcal digestible energy/g) of Nile tilapia juveniles. Fish (average weight 1.7 ± 0.1 g) were distributed in three 40 L aquaria per treatment (13 fish/aquaria) in a completely randomized design. Over 35 days, the fish received the experimental diets three times daily to apparent satiety. The maximum weight gain, feed efficiency ratio, and protein efficiency ratio were recorded in fish supplemented with 14–15 g/kg FA. After 28 days, Enterobacteriaceae was registered only in the gut of tilapia without FA augmentation. Gram-negative bacteria in the fish gut decreased (p < 0.05) in fish receiving 17 g/kg of dietary FA, increased after this level. The intestinal villi height and width were affected (p < 0.05) by FA levels and feeding time. Thus, inclusion of 15 g/kg of FA was effective in promoting growth, improving intestinal morphometry, and decreasing negative gut bacteria of Nile tilapia juveniles after 35 days.
Effect of dietary crude glycerin on the productive performance of nile tilapia fingerlings RAFAEL E. BALEN, WILLIAM F. CARNEIRO, KATSCIANE A. ROSSATO, LILIAN C.R. SILVA, FÁBIO MEURER Anais Da Academia Brasileira De Ciencias, 2020 The aim of this study was to evaluate the effect of different crude glycerin levels in the diet of Nile tilapia fingerlings (mean initial weight 0.32 ± 0.06 g, n = 450) on growth performance parameters, whole-body composition, blood glucose and liver morphology. Crude glycerin was tested at six different levels (0, 4, 8, 12, 16, and 20%) in diets containing 30% digestible protein and 3,000 kcal kg-1 digestible energy. After 37 days of feeding, the inclusion of crude glycerin resulted in positive effects on final weight, visceral fat, weight gain, feed conversion, specific growth rate and feed intake. The different treatments did not influence fillet yield, glycemia, survival and hepatosomatic index, but intermediate levels of inclusion decreased the area of hepatocytes. Regarding fish body composition, significant differences were found in moisture and ash contents, with no changes in crude protein and total lipid. The inclusion of crude glycerin in the Nile tilapia diet improves growth performance without negatively affecting survival rate and glycemia of fingerlings.
Use of essential oils for Nile tipalia breeders during breeding season André Freccia, Fábio Meurer, Ana Tereza Bittencourt Guimarães, Lilian Dena dos Santos, Lilian Carolina Rosa da Silva, et al. Revista Academica Ciencia Animal, 2020 The present study aimed to evaluate the dietary supplementation of a commercial Saluto® compound containing essential oils extract of cinnamon (Cinnamomum zeylanicum), oregano (Origanum vulgare), rosemary (Rosmarinus officinalis) and pepper (Capsicum sp.) on breeding performance of female and male Nile tilapia (Oreochromis niloticus). The experiment had a completely randomized design with five treatments (0, 50, 100, 150, and 200 ppm of essential oil supplementation) and four repetitions during the breeding season of Nile tilapia.

In the correlations of variables at the female reproductive peak no statistical differences were found for the reproductive parameters and quality of the larvae. The nutritional additive inclusion did not impair reproductive parameters during the 120 days of evaluation, and inclusions above 50 ppm promoted an increase in the hepatosomatic index of Nile tilapia females during the reproductive season.
Alcoholic extract of propolis in nile tilapia post-larvae and fingerlings’ diets: Effects on production performance, body composition and intestinal histology LILIAN D. DOS SANTOS, IZABEL V. ZADINELO, LILIAN C.R. DA SILVA, ROGÉRIO L. ZILLI, MARCO ANTONIO B. BARREIROS, et al. Anais Da Academia Brasileira De Ciencias, 2019 The aim of this study was to evaluate the production performance of Nile tilapia post-larvae and fingerlings fed with increasing levels of alcoholic extract of propolis into diets. In Experiment 1, 1800 post-larvae were distributed in 30 tanks, in a completely randomized design with five treatments composed by the inclusion of 0, 1, 2, 3 and 4 g of dry propolis/kg of feed, and six replicates. In experiment 2, 1600 fingerlings were distributed in the same system and designed as experiment 1. No significant effect was observed between treatments, for final weight, total and standard length, survival, and intestinal villus height. However, the propolis extract inclusion of 1 g/kg in Nile tilapia post-larvae and fingerlings' feed resulted in a better body condition factor and higher body protein deposition (p<0.05). The condition factor is an estimate for the future growth of the animals, possibly the fish treated with propolis extract will present better growth, survival and greater reproductive potential rates. The results of the present study demonstrate that alcoholic extract of propolis improves the nutritional condition of Nile tilapia post-larvae and fingerlings, potentially leading to increased productivity in subsequent stages, as well as leading to improvement in fingerlings muscle deposition.
Digestible energy and inclusion of crude glycerin in diets for curimbatá juveniles Rafael Ernesto BALEN, Gilson BUENO JUNIOR, Leda Maria Saragiotto COLPINI, Robie Allan BOMBARDELLI, Lilian Carolina Rosa da SILVA, et al. Boletim do Instituto De Pesca, 2017 O curimbatá é um importante recurso pesqueiro, porém pouco se sabe sobre suas exigências nutricionais. O objetivo deste trabalho foi determinar o coeficiente de digestibilidade aparente (CDA) e o efeito da inclusão da glicerina bruta (GB) em dietas para juvenis do curimbatá Prochilodus lineatus. Foram coletadas fezes de peixes alimentados com dieta-referência, baseada em ingredientes de origem vegetal, e com dieta-teste, tendo o marcador inerte óxido de cromo III (0,1%). No experimento de crescimento foram utilizados 750 juvenis (18,71±2,70 g) em delineamento experimental inteiramente casualizado, com seis tratamentos (dietas contendo 0, 4, 8, 12, 16 e 20% GB) e cinco repetições, durante 64 dias. Para P. lineatus, a GB apresentou CDA de 0,76 para energia bruta e energia digestível de 2.850,99 kcal kg-1 da dieta. Os diferentes níveis de inclusão afetaram o peso final (PFM), conversão alimentar (CAA), taxa de crescimento específico (TCE) e ganho de peso (GPM), assim como os níveis sanguíneos de glicose e triglicerídeos. A análise de regressão mostrou efeito linear negativo das dietas sobre PFM, TCE e GPM e efeito linear positivo sobre CAA. A glicerina bruta pode ser utilizada como fonte de energia e sua inclusão em 4% da dieta promove melhor desempenho produtivo do curimbatá.
