13. HÍBRIDOS DE QUITOSANA-ARGILA PARA ENCAPSULAMENTO E LIBERAÇÃO SUSTENTADA DO FERTILIZANTE NITRATO DE POTÁSSIO
The use of controlled release fertilizers is a trend for improving productivity, reducing costs and environmental pollution. Such materials release gradually the nutrients to the plant in order to supply its requirement and are an alternative to improve fertilization. The preparation of a microsphere from natural materials (chitosan and montmorilonite clay)

15. Development and evaluation of iron-rich meatloaves containing pork liver for schoolchildren
AbstractIron deficiency is a highly prevalent nutritional problem worldwide and it impacts on the cognitive development of children. Therefore, the aim of this research was to develop meatloaf with high iron content by using in their formulations pork liver. Meatloaves were prepared with additions of 9.98% and 13.31% (formulations A and B) of pork liver in o

17. Nutritive value of Tanzania grass for dairy cows under rotational grazing
A nutritional analysis of Tanzania grass (Megathyrsus maximus Jacquin cv. Tanzânia was conducted. Pasture was managed in a rotational grazing system with a 30-day resting period, three days of paddock occupation and two grazing cycles. Ten Holstein × Zebu crossbred cows were kept within a 2-ha area divided into 11 paddocks ha-1. Cows were fed 2 kg of corn

18. Alpha-tocopherol and gamma-tocopherol concentration in vegetable oils
Vegetable oils are the richest dietary sources of vitamin E. Vitamin E determination levels in foods are of great importance to adjust the ingestion of nutrients by the population. The purpose of this paper is to determine the concentration of alpha-tocopherol and gamma-tocopherol in vegetable oils and compare the alpha-tocopherol value to the nutritional re

19. Digestible lysine requirements of broilers
Modern broilers have been submitted to continuous genetic improvement, and therefore, their nutritional requirements must be constantly updated to ensure their performance. Two experiments were carried out to evaluate different digestible lysine levels for starter (1021 days) and grower (22-35 days) phases. The experiments were carried out with male and fema

20. Nutritional requirements of digestible threonine for growing meat-type quails
The objective of this study was to estimate the nutrient requirements of digestible threonine for meat-type quails (Coturnix coturnix sp) in the growth phase. A total of 1350 not sexed meat-type quails were distributed in a completely randomized design with six threonine levels (10.80, 11.50, 12.20, 12.90, 13.60 and 14.30 g/kg as fed), five replications and

22. Modelos matemáticos para predição das exigências nutricionais da colina para frangos de corte / Mathematical models for prediction of nutritional requirement of the choline for chicks
A colina é um nutriente essencial nas dietas de frangos de corte. Os valores de exigências nutricionais são variáveis e foram estabelecidos há muitos anos. Assim, o objetivou-se com este trabalho reavaliar as respostas de frangos de corte de alto potencial genético de 1 a 7, 1 a 14 e 1 a 21 dias de idade como também modelar as respostas por diferentes

23. Calcium levels and calcium: available phosphorus ratios in diets for white egg layers from 42 to 58 weeks of age
The experiment was conducted to determine the nutritional requirement of calcium and the best calcium:available phosphorus ratio for commercial layers at the post-laying peak. A total of 324 Hy-Line W-36 laying hens were utilized in the period from 42 to 58 weeks of age, distributed in a completely randomized design in a 3 × 3 factorial arrangement, compose
