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 ...
Short-term cycles of feed deprivation and refeeding promote full compensatory growth in the Amazon fish matrinxa (Brycon amazonicus)
(Elsevier B.V., 2014-09-20)
Developing nutritional strategies that can reduce production costs for the fish industry without affecting productive performance is paramount to make the activity sustainable. We investigated if short-term cycles of feed ...
Feeding behavior of growing-finishing pigs reared under precision feeding strategies
(Amer Soc Animal Science, 2016-07-01)
The feeding behavior of growing-finishing pigs reared under precision feeding strategies was studied in 35 barrows and 35 females (average initial BW of 30.4 +/- 2.2 kg) over 84 d. Five different feeding programs were ...
Feeding level and frequency for freshwater angelfish
(Sociedade Brasileira de Zootecnia, 2012-06-01)
The objective of this study was to determine the optimal feeding level and feeding frequency for the culture of freshwater angelfish (Pterophyllum scalare). A randomized block design in a factorial scheme (3 × 2) with three ...
Global liver gene expression differences in Nelore steers with divergent residual feed intake phenotypes
(Biomed Central Ltd, 2015-03-25)
Background: Efficiency of feed utilization is important for animal production because it can reduce greenhouse gas emissions and improve industry profitability. However, the genetic basis of feed utilization in livestock ...
