1. Evaluation of an herbal choline feed plant additive in lamb feedlot rations
ABSTRACT An experiment was carried out to evaluate the effect of an herbal choline feed plant additive on the productive parameters and blood metabolites of finishing lambs. Forty male Hampshire × Suffolk lambs (initial body weight of 30.36±3.75 kg) were assigned according to a completely randomized design. Treatments consisted of dietary inclusion of the

2. Replacing sodium bicarbonate with half amount of calcareous marine algae in the diet of beef cattle
ABSTRACT This study evaluated the effects of feeding calcareous marine algae or sodium bicarbonate as rumen buffer on the performance, behaviour, in vitro diet digestibility, and meat quality of beef cattle. A total of 180 Charolaise bullocks (536±38 kg; 14±1 months of age) were divided into two homogeneous groups and fed a diet with a mineral mix containi

5. Effects of Dietary Brewery Spent Grain Inclusion on Egg Laying Performance and Quality Parameters of Bovans Brown Chickens
ABSTRACT Poultry rations are composed mainly of conventional cereal grains and proteins. Using non-conventional agro-industrial by-products may reduce the cost of production and thereby improve productivity. A study was conducted to evaluate the effect of dietary brewery spent grain inclusion on egg laying performance, quality parameters of bovans brown and

6. PERTINENCE CURVES IN FUZZY MODELING OF THE PRODUCTIVE RESPONSES OF BROILERS
ABSTRACT The selection of the type of fuzzy systems pertinence curve allows a better representation of the mathematical model and a smaller simulation error. We aimed to study the effect of pertinence curves in fuzzy modeling of broiler performance, created in different production systems. For the development and testing of fuzzy models, three commercial avi

7. METHIONINE PLUS CYSTINE TO LYSINE RATIO IN DIETS FOR TAMBAQUI JUVENILES
RESUMO Objetivou-se determinar a relação da metionina mais cistina com a lisina em rações para juvenis de tambaqui (Colossoma macropomum). Utilizou-se 600 juvenis de tambaqui com pesos iniciais de 0,28 ± 0,08 g e 0,94 ± 0,33 g em delineamento em blocos ao acaso, com seis tratamentos, cinco repetições em dois blocos, e vinte peixes por repetição, du

8. Poultry by-product meal as dietary protein source for dourado, Salminus brasiliensis: an economic appraisal
ABSTRACT: The dourado, Salminus brasiliensis, a large, carnivorous, Neotropical, Characin, is highly regarded for fish farming and sport fishing alike. However, studies on the farming and husbandry of dourado are still scarce. This study evaluated the performance of dourado fed diets formulated so as to contain increasing levels of poultry by-product meal as

9. Effect of enzyme addition on energy utilization and performance of broiler chickens fed wheat-based diet with different metabolizable energy levels
ABSTRACT. An experiment was carried out to investigate the effect of multi-enzyme in high and low levels of metabolizable energy (13.81 and 11.51 MJ kg-1 diet) on performance and energy utilization of broilers fed wheat-soybean meal diets from 0 to 21 days of age. Result showed that birds fed diets containing 11.51 MJ kg-1 consumed significantly (p < 0.05) m

10. Common moist diet replacement to promote sustainable Cobia Rachycentron canadum (Linnaeus) near- shore farming in Brazil
ABSTRACT: Cobia is one of the most promising warm water aquaculture species. In Brazil, cobia farming began in 2008 in the state of Rio de Janeiro from experimental scale facilities to regular near-shore farms based on fresh/frozen fish diets composed mostly of Sardinella sp. Despite the encouraging results achieved in the promotion of sustainable cobia farm

11. Feeding rate and feeding frequency affect growth performance of common snook (Centropomus undecimalis) juveniles reared in the laboratory
ABSTRACT The effects of feeding rate and feeding frequency on the growth of laboratory-reared common snook (Centropomus undecimalis) were evaluated. Juveniles with mean±SD weight of 2.55±0.48 g and total length of 6.81±0.48 cm were divided into groups of 20 fish and reared in 30 polyethylene tanks of 50 L for 60 days. The experimental design was a 3 × 3

12. Feeding frequency affects feed intake and growth in juvenile pirarucu (Arapaima gigas)
RESUMO O pirarucu é uma das principais espécies de peixe para o desenvolvimento da aquicultura na região amazônica. Neste trabalho foi avaliada a frequência de alimentação ideal para juvenis de pirarucu com base em crescimento e eficiência alimentar. Juvenis de aproximadamente 80 g foram alimentados uma, duas, três ou quatro vezes ao dia até a saci
