There is little information on the nutrition of red-winged tinamous (Rhynchotus rufescens) reared in captivity, and their nutritional requirements still need to be determined. This study aimed at determining dietary crude protein requirements and testing four organic selenium supplementation levels in the diet of red-winged tinamous during the breeding season. Birds were housed in a conventional broiler house divided in 16 boxes with one male and three females each. Iso-energy (2800kcal ME/kg) pelleted feeds, based on corn and soybean meal, were supplied in tube feeders. In the first experiment, treatments consisted of four different diets containing different crude protein (CP) contents (15, 18, 21, or 24%) and in the second experiment, the four diets...

Effect of Environmental Temperature During the First Week of Brooding Period on Broiler Chick Body Weight, Viscera and Bone Development
Provedor de dados: 89
Autores: Moraes,VMB; Malheiros,RD; Furlan,RL; Bruno,LDG; Malheiros,EB; Macari,M.
The objective of the present study was to assess the development of broiler chicks during the first week post-hatching when reared at three different environmental temperatures. A total of 480 day-old chicks were placed in three environmentally controlled rooms (20, 25 and 35°C) from 1 to 7 days of age. Body weight gain, feed and water intake, as well as liver, gizzard, heart, yolk sac and bursa of Fabricius weights were measured daily. Tibia and femur bones were weighed and their length and width (medial diameter) were also obtained. The chicks reared at 20º C had lower weight gain and ingested less food than chicks reared at 25°C and less water than chicks kept at 35°C. Relative weights of the liver, heart, and gizzard were affected by environmental...

Composição e Digestibilidade dos Aminoácidos das Sojas Integrais Processadas para Aves
Provedor de dados: 89
Autores: Café,M B; Sakomura,NK; Junqueira,OM; Malheiros,EB; Del Bianchi,M.
O presente trabalho foi realizado com o objetivo de determinar a composição em aminoácidos e os coeficientes de digestibilidade dos aminoácidos da soja integral extrusada, tostada e do farelo de soja reconstituído de óleo. Foi utilizada a metodologia da alimentação forçada (Sibbad, 1976) com galos adultos. Para o cálculo dos coeficientes de digestibilidade dos aminoácidos das sojas testadas, foram consideradas as perdas endógenas e metabólicas obtidas de galos em jejum. Os dados médios de digestibilidade verdadeira de todos os aminoácidos testados foram de 91,1% para a soja extrusada, 78,6% para a soja tostada e 90,5% para o farelo de soja. Os resultados obtidos permitem concluir que a digestibilidade dos aminoácidos da soja integral tostada foi inferior a...

Atividade enzimática pancreática de frangos de corte alimentados com dietas contendo enzima ou probiótico
Provedor de dados: 89
Autores: Lima,ACF; Macari,M; Pizauro Júnior,JM; Malheiros,EB.
Este trabalho foi realizado para avaliar o efeito da adição de enzima e/ou probiótico, bem como do estresse calórico sobre a atividade de enzimas digestivas de frangos de corte aos 7, 14, 28 e 42 dias de idade. O delineamento experimental utilizado foi o inteiramente casualizado em parcelas subdivididas com 6 tratamentos primários, constituindo um esquema fatorial 6x2 (rações x temperatura) e 4 tratamentos secundários (idades de amostragem), com 2 repetições. Não foi verificado efeito significativo dos tratamentos sobre a atividade específica das enzimas, exceto para as atividades de amilase aos 14 dias e tripsina aos 28 dias de idade, nas quais a adição de enzima proporcionou maiores atividades. Já a idade de criação afetou significativamente todas as...

Influence of sex, age, and fasting on blood parameters and body, bursa, spleen and yolk sac weights of broiler chicks
Provedor de dados: 89
Autores: Pires,DL; Malheiros,EB; Boleli,IC.
The effects of water and feed fasting for 24, 48 and 72 hours post-hatching on blood parameters (mean corpuscular volume, MCV; red blood-cell, RBC; hematocrit, HCT; hemoglobin, HGB; plasma glucose, CGP; plasma total protein, PP, and differential leukocytes count), and on body, liver, spleen, bursa, and yolk sac weights were analyzed. Erythrogram data were obtained with a blood cell counter. Total plasma protein and plasma glucose were determined by using the Bradford method (1976) and a glucose PAP liquiform kit (Labtest, cat. n. 84), respectively. Specific leukocyte counts were carried out on blood smears stained with Rosenfeld solution. According to the obtained data, water and feed post-hatching fasting reduced MCV values, which also were lower in males...

Evaluation of babassu meal in feed for layer hens during the growth phase
Provedor de dados: 89
Autores: Carneiro,MIF; Sakomura,NK; Malheiros,EB; Araújo,JA; Silva,EP da; Kawauchi,IM; Fernandes,JBK; Sousa,JRST de.
Studies were conducted to evaluate the nutritional value and inclusion levels of babassu meal (BM) in the diet of grower layer pullets in substitution to wheat meal. Digestibility, metabolism and growth trials were conducted. Twelve cecectomized roosters were used in the digestibility assay to determine the coefficients of standardized digestibility of amino acids (CSDAA). The metabolism trial was conducted with 30 adult roosters to determine the apparent metabolizable energy corrected for nitrogen (AMEn) of BM. A growth trial was performed to determine replacement levels of wheat midds by BM diet using 360 six-week-old commercial layer pullets. BM was included at the 0, 75 and 150 g/kg of BM, during grower and development rearing phases, respectively....
