2. Nutritional plans of digestible phosphorus for gilts from 30 to 100 kg
ABSTRACT The objective of this study was to evaluate sequential digestible phosphorus levels for gilts from 30 to 100 kg. Sixty gilts were used, with an initial weight of 29.98±3.37 kg and final weight of 100.66±8.82 kg, distributed in a randomized block design, with five nutritional digestible phosphorus levels: 2.19-1.88-1.68, 2.69-2.38-2.18, 3.19-2.88-2

3. PHOSPHORUS REQUIREMENT OF TAMBAQUI FINGERLINGS
RESUMO Objetivou-se determinar a exigência de fósforo digestível em rações para alevinos de tambaqui (Colossoma macropomum). Utilizou-se 900 alevinos (0,51 ± 0,06 g), em delineamento inteiramente casualizado, com seis tratamentos, cinco repetições, e trinta peixes por unidade experimental. Os tratamentos constituíram-se de seis rações com diferent

4. Determination of nutrient and energy values of cottonseed meal supplemented or not with phytase and protease for broiler chicks
ABSTRACT The objective of this study was to determine the nutritional and energy compositions of cottonseed meal (CM), with or without enzyme supplementation, for broilers at different ages. A total of 672 male Cobb 500 chickens were distributed into four metabolism and ileal-digestibility trials. The experimental design was completely randomized, with four

5. Effect of observed individual data of performance and excretion on life cycle assessment of piglets
ABSTRACT: The objective was to evaluate the impact of producing piglets fed diets with different crude protein (CP) levels through life cycle assessment and experimental data. In Trial I (performance), 28 crossbred barrow piglets, with an initial average weight of 15.3 ± 1.15 kg were divided into a randomized block design with four treatments, seven replica

6. Enzyme complex at different levels in diets with enriched ingredients for commercial laying hens
ABSTRACT The objective of this study was to evaluate levels of inclusion of an enzyme complex (EC) in corn- and soybean meal-based diets for laying hens on the digestibility of nutrients and energy. A metabolism trial was conducted using 75 Dekalb Brown laying hens at 26 weeks of age, which were distributed into five treatments with five replicates in a comp

7. Nutritional plans of digestible phosphorus for growing-finishing barrows
ABSTRACT This study was conducted to evaluate nutritional plans of digestible phosphorus for barrows weighing between 30 and 100 kg. Eighty animals were distributed in a randomized block design with five nutritional plans containing 2.19-1.86-1.71, 2.57-2.23-2.09, 2.94-2.61-2.46, 3.32-2.99-2.84, and 3.70-3.36-3.32 g of digestible phosphorus kg−1 of diet, r

8. Intake, apparent digestibility, rumen fermentation and nitrogen efficiency in sheep fed a tropical legume silage with or without concentrate
Abstract Legume silage can increase the forage quality of the diets as well as supply it with nitrogen, calcium and phosphorus. The objective was to evaluate the intake, apparent digestibility, rumen fermentation and nitrogen efficiency in sheep fed a tropical legume silage with or without concentrate. Twelve crossbred sheep with an average initial body weig

9. Digestible phosphorus levels for barrows from 50 to 80 kg
ABSTRACT This study was carried out to evaluate the levels of digestible phosphorus in diets for barrows with a high potential for lean meat deposition from 50 to 80 kg. Eighty barrows, with an initial weight of 47.93±3.43 kg, were distributed in completely randomized blocks, with each group given five levels of digestible phosphorus (1.86, 2.23, 2.61, 2.99

10. Intake, performance and nutrient digestibility of sheep fed sugarcane treated and ensiled with calcium oxide or urea
The 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 c

11. Immune response of broilers fed conventional and alternative diets containing multi-enzyme complex
The present study aimed at evaluating the effect of adding a commercial multi-enzyme complex to conventional and alternative broiler diets on the immune response and occurrence of lesions in the intestinal mucosa. In total, 900 male broiler chicks were distributed according to a completely randomized design, with six treatments of six replicates each. Two co

12. Protein, calcium and phosphorus requirements in the maintenance of captive-bred capybaras
The objective was to determine the nitrogen-protein, calcium and phosphorus requirements of adult capybaras (Hydrochoerus hydrochaeris) bred in captivity through a nutritional balance study under conditions that favored the occurrence of cecotrophy. In a completely randomized design with four replicates per treatment, 16 adult female capybaras were fed isoca
