Performance of cobia grown in brackish water and fed with different feeding rates
Tosta,Gitonilson Antonio Moreira; Albinati,Ricardo Castelo Branco; Carvalho,Gleidson Giordano Pinto de; Carvalho,Jaciane Vergne deAbstract: The objective of this work was to evaluate different feeding rates on the productive performance of cobia (Rachycentron canadum) grown in brackish waters. For the experiment, 1,600 juveniles were distributed in 16 enclosures installed in an estuarine pond. Four different feeding rates were evaluated: 1, 3, 5, and 7% live weight (LW) per day. The following performance parameters were assessed: survival...
Substitution of soybean meal for urea in diets based on deferred buffelgrass ha...
Pereira,Gildenia Araújo; Oliveira,Juliana Silva de; Santos,Edson Mauro; Carvalho,Gleidson Giordano Pinto de; Araújo,Gherman Garcia Leal deABSTRACT The objective of this study was to evaluate the effect of substituting soybean meal for urea in diets based on deferred buffelgrass on the performance of feedlot sheep. Thirty mixed-breed sheep with an average initial body weight of 17±1.5 kg were distributed in a completely randomized design in which the experimental treatments consisted of five diets with six replicates. Diets were composed of deferr...
Qualitative parameters of pearl millet silage ammoniated with urea, at differen...
Freitas,Poliane Meire Dias de; Carvalho,Gleidson Giordano Pinto de; Santos,Edson Mauro; Araújo,Gherman Garcia Leal; Oliveira,Juliana Silva deAbstract: The objective of this work was to evaluate the effects of urea ammoniation of pearl millet silage, at different compaction densities, on chemical composition, losses in the ensilage process, fermentation profile, microbial population count, and aerobic stability. The experimental design was completely randomized, in a 2×4 factorial arrangement, with two compaction densities (600 and 800 kg m-3) and fo...
Intake, apparent digestibility, production, and composition of milk from cows f...
Murta,Rogério Mendes; Veloso,Cristina Mattos; Pires,Aureliano José Vieira; Silva,Fabiano Ferreira da; Carvalho,Gleidson Giordano Pinto deABSTRACT The objective of this study was to evaluate the effect of different sources of lipids in the diets of dairy cows on the intake and digestibility of nutritional fractions, and milk production and composition. The experiment was conducted in a 42-hectare area divided into eight paddocks covered with Brachiaria brizantha. Twelve crossbred Holstein × Zebu cows were distributed into three simultaneous 4 × 4...
Impact of total substitution of corn for soybean hulls in diets for lambs
Bastos,Milena Patricia Viana; Carvalho,Gleidson Giordano Pinto de; Pires,Aureliano José Vieira; Silva,Robério Rodrigues daThe experiment was conducted to assess the effect of substituting corn for soybean hulls on the apparent digestibility of nutrients, carcass performance and characteristics, and yield of cuts of 25 non-castrated male Santa Ines lambs with an initial body weight of 20±2 kg, at approximately 6 months of age, sheltered individually in stalls (1.10 × 1.0 m), considering a totally randomized design, fed 600 g/kg of ...
Feeding behavior and responses in grazing lactating cows supplemented with pean...
Costa,Emellinne Ingrid de Sousa; Carvalho,Gleidson Giordano Pinto de; Pires,Aureliano José Vieira; Dias,Carina Anunciação dos SantosThis experiment was conducted to study the substitution of soybean meal with peanut cake in the supplement by assessing the feeding behavior and the interaction between the thermal environment and the physiological responses of eight crossbred cows with an average live weight of 500 kg. Cows were divided into two 4 × 4 Latin squares and managed on pasture. The peanut cake was included at the levels of 0, 330, 6...
Análise econômica da utilização de silagens de cana-de-açúcar tratadas com urei...
Martins,Susi Cristina dos Santos Guimarães; Carvalho,Gleidson Giordano Pinto de; Pires,Aureliano José Vieira; Silva,Robério RodriguesObjetivou-se avaliar a viabilidade econômica de dietas contendo quatro silagens de cana-de-açúcar: sem aditivo; com 1% de ureia; com 0,5% de CaO + 0,5% ureia; e com 1% de CaO. Utilizaram-se oito vacas mestiças Holandês × Gir, distribuídas em dois quadrados latinos 4 × 4, compostos de quatro dietas, quatro animais e quatro períodos. A cana-de-açúcar utilizada foi a variedade SP 79-1011, com produção de 140 t/ha/...
Agronomic evaluation of 32 sorghum cultivars in the Brazilian semi-arid region
Perazzo,Alexandre Fernandes; Carvalho,Gleidson Giordano Pinto de; Santos,Edson Mauro; Pinho,Ricardo Martins Araujo; Campos,Fleming SenaThe objective of this study was to evaluate agronomic characteristics of 32 sorghum cultivars (Sorghum bicolor(L). Moench) in the Brazilian semi-arid region. The experimental design was set up in randomized blocks with three replications. Treatments were the 32 sorghum cultivars. The evaluated variables were: plant height, stem diameter, tiller density, number of green leaves per tiller, average leaf length, dr...

Magalhães,Albertí Ferreira; Pires,Aureliano José Vieira; Carvalho,Gleidson Giordano Pinto de; Silva,Fabiano Ferreira da; Nascimento Filho,Carlos SouzaThe objective of this study was to evaluate intake, performance and nutrient digestibility of sheep supplemented with sugarcane ensiled with four levels of calcium oxide (0.0, 0.8, 1.6 and 2.4%) and urea (1.5%), on a natural matter basis. Twenty castrated Santa Ines lambs with 24.09 kg average weight were housed in individual 1.5 m² pens, distributed in a completely randomized design. The diet supplied had a ro...
