1. Simulation of diets for dairy goats and growing doelings using nonlinear optimization procedures
ABSTRACT The objective of this study was to simulate total dry matter intake and cost of diets optimized by nonlinear programming to meet the nutritional requirements of dairy does and growing doelings. The mathematical model was programmed in a Microsoft Excel(r) spreadsheet. Increasing values of body mass and average daily weight gain for growing doelings

2. Formulação de dietas de custo mínimo da matéria seca para bovinos de corte em planilha eletrônica.
ABSTRACT: The diet is one of the main costs animal production in feedlots. In addition, diet composition is one of the main determinants of the animal's performance. Therefore, adequate diet formulation is crucial for the success of the feedlot. This publication describes the fundamentals of diet formulation through the criteria of least cost of dry matter a

3. Evaluation of swine diet formulation based on amino acid digestibility estimates.
Tres experimentos foram conduzidos para testar a hipotese de que dietas formuladas usando valores da digestibilidade verdadeira dos aminoacidos (DVAA) de ingredientes alternativos (IA) resultam em desempenho similar ao obtido com dietas a base de milho e farelo de soja (MFS). A DVAA foi obtida com os metodos ileal em suinos (I) e alimentacao precisa em galos

4. Elaboração de fórmulas enterais artesanais de baixo custo adequadas em fluidez e osmolalidade / Developing of handmade enteral formulations of lower cost adequate in fluidity and osmolarity
The enteral nutrition consists in the administration of nutrients (food and/or nutritional supplements) into the gastrointestinal tract by using a probe when the oral ingestion is inadequate. Handmade preparations represent an option of enteral diet, which consist in solutions in which the foods are used freshly, or food products and/or modules of nutrients.

5. Net energy evaluation of feeds and determination of net energy requirements for pigs
Feeds for pigs can be attributed different energy values according to, first, the step considered in energy utilization (DE: digestible energy, ME: metabolizable energy and NE: net energy) and, second, the method used for estimation at each step. Reference methods for evaluating DE content are based on in vivo digestibility measurements; indirect estimates o

6. Evaluation of coffee hulls as a feedstuff for HolsteinâZebu dairy cows / AvaliaÃÃo da casca de cafà como alimento para vacas leiteiras HolandÃs-Zebu
The objective of this experiment was to evaluate the performance of Holstein-Zebu dairy cows fed concentrates containing 25% of coffee hulls (Coffee) or citrus pulp (Pulp) in substitution to ground corn grain (Corn; 47.4% of the concentrate). Forty two cows were blocked based on milk yield and allocated to one of the three treatments for 56 days, after a 14-
