Limiting amino acids supplementation in low crude protein diets and their impacts on growth performance and carcass composition in Labeo rohita (rohu) adult fish

Braz. j. biol; 83 (), 2023
Abstract Ninety days study was conducted in hapas installed in earthen ponds. Fish of an average initial weight (220g) were evenly distributed in triplicate groups within fifteen hapas. Five experimental diets labeled as T1 (25% CP and NRC recommended amino acid level) as control diet, T2 (with 2% low pr...

Batata-doce em dietas para juvenis de tilápia em substituição parcial ao farelo de milho: uma análise econômica e de variáveis zootécnicas

Rev. bras. ciênc. vet; 29 (4), 2022
Objetivou-se avaliar o desempenho e a viabilidade econômica da substituição parcial do farelo de milho pela farinha de batata-doce, para averiguar se é viável ou não a inclusão nas rações para tilápia. O experimento teve duração de 30 dias entre os meses de maio e junho de 2021 em delineament...

Zootechnical indices and digestibility in juveniles of tambaqui Colossoma macropomum fed a diet containing particulate maize

Braz. j. biol; 82 (), 2022
Three experiments were done with different particle sizes of corn feed on its zootechnical performance, passing rate and apparent digestibility of juvenile tambaqui (Colossoma macropomum). In the first, 200 juveniles were used and distributed in 20 tanks (220 L), 10 fish per unit (four replicates). The e...

Effect of different protein based feed on the growth of mahseer

Braz. j. biol; 82 (), 2022
For the proper growth of fish, it is necessary to feed the fish with a proper and balanced diet. A study was conducted to find out the effect of different protein-based diets on fingerlings of Tor putitora (mahseer). A feed with dietary protein levels of 35%, 40%, 45%, and 50% were prepared. The effect o...

Particle size of oyster shell meal and calcium: phosphorus ratios in broiler diets

Ciênc. rural (Online); 52 (10), 2022
The effects of Ca:P total ratio and particle size of oyster shell meal (OSM) were evaluated in broiler diets. In Experiment 1, 800 broilers (22-42 days old) were distributed in a 2×2 factorial design, with two Ca:P ratios (1.7 and 2.0:1) and two OSM particle sizes (coarse = 1,354 µm and fine = 428 µm)...
