THEORETICAL CLASSES - Introduction. Animal production and nutritional requirements of mankind. The importance of animal nutrition within animal production industry. Overview of compound feed production. - Analytical composition of animals and plants. Main factors affecting body composition. Methods for the estimation of in vivo animal body composition. - Animal growth. Physiological basis of growth. Characterization of growth curves. Definition of precocious animals and of compensatory growth. Main factors affecting animal growth. - Proximate analysis of feeds by the Weende and Van Soest approaches. Reference to other analytical techniques routinely used in animal nutrition labs. - Digestive processes. Functional anatomy of the digestive tract. Digestive enzymes. Microbiological fermentation of feeds. Main factors affecting digestibility. Methods used in digestibility evaluation. Methods used in feces collection. True and apparent digestibility. - Nutritional energetics. Conventional scheme of diet energy partition. Main factors affecting diet energy utilization. Efficiency of energy utilization for maintenance and production. Use of direct and indirect calorimetry for estimation of heat production. Establishing energy balances. - Requirements and metabolism of nutrients: o Carbohydrates. Functions. Classification and characterization. Utilization of carbohydrates in different species. o Lipids. Functions. Classification and characterization. Essential fatty acids. Methods for evaluating lipid quality. Lipid oxidation. Qualitative and quantitative fatty acid requirements. Utilization of lipids in different species. o Proteins and amino acids. Functions. Classification and characterization. Essential and non-essential amino acids.

Evaluation Type

Evaluation with final exam

Assessment Components

designation	Weight (%)
Participação presencial	0,00
Exame	100,00
Total:	100,00

Eligibility for exams

Students must attend 2/3 of the practical classes to have access to the final exam.

Calculation formula of final grade

Students may do 2 mid term written exams and will be aproved if the sum of the two exams is higher than 9.5 values. Students may do a final written exam and will be aproved if classification is higher than 9.5 values. Students that are aproved in the mid term exams may also do the final exam but then only the final exam classification will be considered.
