Feed digestibility and productive performance of bullfrogs raised in cages and fed in different periods and high frequency
(Elsevier B.V., 2014-09-20)
Three feeding frequencies (24, 48 and 96 meals/day) and three feeding periods (daytime, nighttime and daytime/nighttime) were evaluated in this experiment. Bullfrogs (Litho bates catesbeianus), with average weight of 78.6 ...
COMPARISON BETWEEN TWO FEEDING RATES AND THREE FEEDING FREQUENCIES FOR HYBRID SURUBIMS REARED IN CAGES
(Univ Fed Rural Semi-arido-ufersa, 2018-07-01)
This study evaluated the effects of feeding frequency and feeding rate on productive performance of hybrid surubims reared in cages with automatic feeding. Three feeding frequencies (6, 12 and 24 meals day(-1)), and two ...
Feeding rate for pacu reared in net cages
(2012-07-01)
The objective of this study was to evaluate the feeding management of pacu juveniles (P. mesopotamicus) under different feeding rates and its relation with productive performance, body composition and hematological ...
Automatic feeders for Nile tilapia raised in cages: productive performance at high feeding frequencies and different rates
(Arquivo Brasileiro Medicina Veterinaria Zootecnia, 2016-05-01)
The main goal of modern intensive fish farms should be to increase productivity at a low cost. The automation of fish feeding plays an important role in this scenario since it may improve feed efficiency and reduce organic ...
Feeding frequency on the production viability of production and quantitative descriptors of parasitism in angelfishFrequência alimentar na viabilidade de produção e na descrição quantitativa de parasitas em acará bandeira
(2016-02-01)
Angelfish (Pterophyllum scalare) is a very important species in Brazil’s domestic market, however feeding managements differ from fish breeders to aquarists, so the cost of feed and labor become relevant items when cultivating ...
Feed digestibility and productive performance of bullfrogs fed in high and low frequency
(Elsevier B.V., 2012-01-25)
This study evaluated the effect of the feeding frequency on growth performance of bullfrogs (Lithobates catesbeianus) and established the coefficients of availability of calcium and phosphorus and the coefficient of ...
Polyculture of frogs and tilapia in cages with high feeding frequency
(Elsevier B.V., 2014-07-01)
The polyculture of frogs and tilapia was evaluated in 12 pens made of polypropylene, installed within cages linearly distributed in a pond. 43 bullfrogs (Lithobates catesbeianus) with 79.1 +/- 16.9 g were distributed in ...
Feeding strategy with alternate fasting and refeeding: effects on farmed pacu production
(Wiley-Blackwell, 2011-04-01)
P>A 36-day trial was conducted to determine the effects of repetitive periods of food restriction and refeeding on growth and energy metabolism in pacu (Piaractus mesopotamicus). A total 264 juvenile fish (36.9 +/- 2.8 g) ...
Rearing of Nile tilapia (Oreochromis niloticus) juveniles in a biofloc system employing periods of feed deprivation
(2020-04-02)
The study aimed to evaluate if different periods of feed deprivation could affect the productive and economic performance of Nile tilapia juvenile reared in biofloc technology (BFT) during nursery phase. During 56 days, ...
Effect of feedlot design and management on the fate and distribution of monensin
(Taylor & Francis, 2013-02-27)
Feedlots produce a range of trace chemicals that impact human health and/or the environment. The most widely used growth promoter in intensive cattle production in Argentina is monensin, an ionophore polyether with ...
