Apparent nutrient digestibility of carbohydrate (corn) in Cirrhinus mrigala under the influence of chromium chloride hexahydrate

Braz. j. biol; 80 (3), 2020
Abstract A feeding trial was carried out to assess the effect of dietary chromium supplementation on apparent nutrient digestibility coefficient (%) of gelatinized and non-gelatinized corn in Cirrhinus mrigala fingerlings for 90 days. Using various levels of chromium chloride hexahydrate six test diets d...

Effect of replacing fish meal by full fat soybean meal on growth performance, feed utilization and gastrointestinal enzymes in diets for African catfish Clarias gariepinus

Braz. j. biol; 80 (3), 2020
Abstract Study aimed to evaluate the effect of replacing fish meal with different levels of full fat soybean meal (FFSBM) on growth and digestive enzyme activities in the stomach, Liver and intestine for Clarias gariepinus. Four diets (D1, D2, D3 and D4) were formulated with 0, 15, 20 and 20 g 100-1 prot...

Brazilian red pepper leaves essential oil (Schinus terebinthifolius) in diets for feedlot lambs

Essential oil (EO) from Brazilian red pepper leaves contains antimicrobial compounds that control Gram-positive bacteria in the rumen content, improving the efficiency of ruminal fermentation. The objectives of the present study were to evaluate the effects of the Brazilian red pepper leave...

Comparative analysis of the diet composition and its relation to morphological characteristics in Achirus mazatlanus and Syacium ovale (Pleuronectiformes: Osteichthyes) from a Mexican Pacific coastal lagoon

Neotrop. ichthyol; 18 (1), 2020
The purpose of this research was to investigate differences in diet composition between Achirus mazatlanus and Syacium ovale, two flatfishes inhabiting in a tropical coastal lagoon and to investigate the relationship of their feeding habits to size, body morphometry and mouths characteristics. Fish were ...

Digestibilidade aparente do farelo de palmiste em tambaqui (Colossoma macropomum)

O objetivo deste trabalho foi determinar a digestibilidade do farelo de palmiste (Elaeis guineensis) para o tambaqui (Colossoma macropomum), em duas classes de peso: 1 (210 alevinos de 4,45±1,18g) e 2 (54 juvenis de 115,91±4,01g). Os coeficientes de digestibilidade aparente (CDA) da matéria seca, prot...

Substituition of urea for soybean meal and forced intake of minerals on the performance of growing crossbred calves

Forty eight crossbred calves, 24 males and 24 females, with weight and age of 203.6±3.7kg and 11.8±1.0 months were allotted to the following treatments: MT- mineral salt ad libitum and sugar cane mixed with 10g kg-1 mixture of urea and ammonium sulfate in a 9:1 proportion; MA - sugar cane mixed with 16...

Composição nutricional e valores energéticos determinados com frangos de corte de coprodutos do processamento do etanol de milho

It was determined by the total collection of excreta method, with broilers from 22 to 32 days of age, the coefficients of apparent metabolism of dry matter, crude protein and crude energy and apparent metabolizable energy corrected for zero nitrogen balance (AMEn) of the ethanol co-products of corn: acid...

Objetivou-se avaliar o comportamento ingestivo de cordeiros Santa Inês alimentados com resíduo de cervejaria desidratado (RCD). Foram utilizados 35 cordeiros, machos, não castrados, com peso médio inicial de 16,00±1,69kg e, aproximadamente, 70 dias de idade. Adotou-se o delineamento inteiramente ao ...

Does intensive feeding frequency affect growth performance of common snook Centropomus undecimalis (Bloch, 1792)?

Braz. j. biol; 79 (3), 2019
Abstract Salt water recirculation systems using automatic feeders are a new frontier for marine aquaculture. It is possible to decrease the vulnerability of the traditional fish farming in open systems and reduce wasteful feeding and discharge of effluents, as well as increase the economic returns. An e...

Diet selenium improves the antioxidant defense system of juveniles Nile tilapia ( Oreochromis niloticus L)

Braz. j. biol; 79 (3), 2019
Abstract From the advancement of tilapia production in recent years, diets are sought that allow the maximum growth, improving health and fish quality. In this study growth, biochemical, hematological and oxidative parameters were evaluated of tilapia fed with increasing selenium levels: 0.53, 0.86, 1.0...
