The use efficiency and feed conversion of extruded pelletized diets were compared. Eight isoproteic (220 g kg⁻¹ digestible protein) assayed for 90 days in a 2 x multifactorial design with two carbohydrate levels (400 500 kg⁻¹), lipids (40 80 kg⁻¹) diet processing (pelletization extrusion) three repetitions. growth Piaractus mesopotamicus fed these the quality control indices gauged. density was lower as level 400 lipid 40 kg⁻¹. interaction presented higher leaching value low diet. Fish best...
Growth and metabolism were investigated in juvenile tambaqui (Colossoma macropomum) fed with isoenergetic diets four treatments protein (P) lipid (L) g kg−1: P350L49; P301L81; P253L113 P205L145, respectively. The experiments carried out the laboratory facilities. Fish growth, intermediary metabolites (total sugar, lactate, pyruvate, ammonia, protein, fatty acids, triacylglycerols, amino acids glycogen), enzyme activities of lactate dehydrogenase, malate glutamate aspartate aminotransferase...
Farming of the freshwater fish is emerging in Brazil and many species from wild are promising. The teleost matrinxã (Brycon cephalus) holds several characteristics such as fast growth rate, high commercial value adaptability to artificial raring conditions, which make it a promising for commerce. use pesticides aquatic environment frequent Brazil, methyl parathion very common aquaculture. We have determined enzymatic activity acetyl cholinesterase white muscle brain exposed 2ppm...
The responses of the digestive physiology juvenile pacu to different diet processing were studied. Fish fed with isoproteic diets 260 g kg−1 crude protein (CP) containing levels carbohydrate (DCh) (400 or 500 kg−1), and two (pelletization extrusion) for 90 days. extruded showed decrease gastrointestinal transit time (GI transfer) amylase activity, but maltase activity did not alter. Protease intestine depicted increase when DCh was raised. also caused enhancement apparent digestibility...
The objective of this work was to evaluate the effect pelletized or extruded diets, with different levels carbohydrate and lipid, on gastrointestinal transit time (GITT) its modulation in pacu (Piaractus mesopotamicus). One hundred eighty juveniles were fed eight isonitrogenous diets containing two (40 50%) lipid (4 8%). Four four extruded. Carbohydrate experimental caused no changes bolus time. However, permanence related diet processing. Fish exhibited highest Regression analysis behavior...
In fish, studies on a wide variety of physiological effects exercise have been reported since long time. It has attributed special attention to some types exercise, however, its application as healthful practice in the rearing and welfare farming fish is rising last few years. this particular, long-term intermittent sustained swimming (ISS) not yet explored. work, freshwater Brycon amazonicus was submitted for 30 days at velocity 1.0 body-length sec-1 12h interspaced by under still water....
The student must be alphabetized to able read maps, as well learning write and proficient at the required mathematics. children that has never created his own cartographic representation plenty of difficulties when it comes understanding a map. In this article, some lived experiences are recounted based on proposals elaborated for work unites research, teaching extension which aims preparing professors initiate alphabetization programmes in their respective schools.
O objetivo deste trabalho foi comparar o método de quantificação óxido cromo pelo espectrofotometria absorção visível e atômica nas dietas fezes pacu para determinação dos coeficientes digestibilidade aparente extrusadas ou peletizadas. ensaio realizado com 180 pacus (69,6 ± 17,9 g). Os peixes foram alimentados as contendo 26% proteína bruta 4022,3 Kcal.kg-1 energia, sendo um lote desta dieta peletizadas outro extrusadas, acrescidas 0,5% Cr2O3 em sua formulação. Amostras ingredientes,...
The objective of this work was to evaluate the effect macronutrients and essential amino acids on digestive process freshwater teleost Matrinxã (Brycon amazonicus). Juveniles were fed with diets containing starch plus free or oil for 15 days. These fish compared others without addition acids. After experimental span, 12 from each treatment randomly sampled collect stomach, pyloric cecum, anterior posterior intestine assaying enzymes activity. Increase gastric proteolysis due dietary...
