An estimation of optimum dietary concentration of soy bean meal for carps (Catla catla, Labeo rohita and Cirhinus mrigala)

Braz. j. biol; 84 (), 2024
Abstract Soybean meal is an inexpensive plant origin protein which has been used in practical diets as a replacement of animal protein such as fish meal or chicken meal, due to the uneconomical price of animal protein diets. Consequently, a research study was conducted on some commercial species of India...

Effects of Se nanoparticles supplementation on growth performance, hematological parameters and nutrient digestibility of Labeo rohita fingerling fed sunflower meal based diet

Braz. j. biol; 84 (), 2024
Abstract The aim of the present study is to assess the effects of selenium nanoparticles on the growth, hematology and nutrients digestibility of Labeorohita fingerlings. Fingerlings were fed with seven isocaloric sunflower meal-based diet supplemented with different concentrations of nanoparticles namin...

Can Saccharomyces cerevisiae supplementation improve piglets’ performance and intestinal health after weaning?

This study aimed to assess the impact of two commercial Saccharomyces cerevisiae strains (CHY1 and CHY2) on the intestinal health and performance of weaned piglets challenged with enterotoxigenic Escherichia coli during the nursery phase. One hundred ninety-two piglets with an average weight of 6.70 ± 0...

Use of phytase and citric acid supplementation on growth performance and nutrient digestibility of Cirrhinus mrigala fingerlings fed on canola meal based diet

Braz. j. biol; 83 (), 2023
Abstract Fishmeal; being a limited and costly feed ingredient is continuously been substituted with locally available plant proteins. However, the occurrence of anti-nutritional factors in plant meal suppresses its potential to be fully replaced. Therefore, in this study we aimed to study the synergistic...

Inclusão da ractopamina na nutrição de peixes: revisão de literatura

A demanda da população mundial por produtos aquáticos esta se incrementando, enquanto que a produção da pesca extrativa reduzindo, alcançando em muitos casos, seu máximo potencial produtivo. Como consequência, não será possível em curto prazo, sustentar o fornecimento de produtos aquáticos, d...

Effect of exogenous emulsifier and different fat sources on the performance, carcass characteristics, nutrient digestibility, and serum lipid profile of broiler chickens

A study was conducted to evaluate the effect of an emulsifier on reduced-energy diets using two fat sources for broilers. The study was designed as a 2 x 3 factorial arrangement of treatments. The first factor was 2 fat sources (poultry fat or beef tallow). The second factor was a basal diet with the rec...

Replacement level of rubber seed cake for soybean meal on the growth of Japanese quail

Braz. j. biol; 82 (), 2022
A four-week feeding trial on the simultaneous replacement of 0 to 50% of soybean meal and 0 to 100% of soybean oil on the growth performance, carcass composition and profitability was conducted using 45 randomly chosen one-week-old growing Japanese quail. The five experimental diets were; D0 = Diet conta...

Blood metabolites and fecal starch as indicators of feed efficiency of beef cattle in the feedlot

The use of blood metabolites (BM), fecal starch (FS), and apparent digestion of starch, (ATTSD) as indicators of feed efficiency (FE) in beef cattle in the feedlot was studied. Fourteen bulls were used, originating in an industrial cross, without a defined racial group, with mean body weight of 284.86kg,...

Nutritive evaluation, metabolisable energy and digestible amino acid contents of different indigenous feedstuff for Nile tilapia (Oreochromis niloticus)

Braz. j. biol; 81 (1), 2021
Abstract Three trials were executed to examine the nutritive profile, metabolisable energy and digestible amino acid (AA) contents of four indigenous feed ingredients including wheat (W), wheat middling (WM), canola meal (CM) and rapeseed meal (RSM) in Nile tilapia. Three samples of each test ingredient ...
