principle of animal nutrition lecture notes

You’ve got fat-soluble and water-soluble vitamins. - Phosphorus(P): damage and may cause also chronic hypersensitivity. o Part of ferritin an hemosiderin for storage, Factors depressing the digestion of carbohydrates: Differences between forages (roughages), concentrates and by-products o Polysaccharides For any animal, a nutritionally adequate diet must satisfy three nutritional needs: A balanced diet must provide fuel for cellular work. - Animal species 16% 9. - Conjugated proteins: proteins that contain compounds of a non-protein nature(e.g. bags filled with diet samples are placed either in the rumen or in the ileal tract. explain the factors that affect feed intake and efficiency of feed utilization in farm animals. - In felids: they do not possess Δ6-desaturase  long chained PUFA essential, Minerals: The fat soluble contain carbon, hydrogen and They may taste and smell buds so they don’t discriminate between feedstuffs. An important constituent of the animal or plant body is water. NAF’s (which role plays processing on the effectiveness of NAF’s) about the digestibility for the animal itself. Protein evaluation is about amino acid composition en digestibility while energy evaluation contains lipids, protein-carbohydrates), Fatty acids: Principles of Animal Nutrition 2018 PDF Book. And maybe even a reduced methane emission All Veterinary ANIMAL NUTRITION Presentations. These are Lecture Notes for Undergraduate learners as prepared by Lecturers of the Muslim University of Morogoro. Nutritional status can be both the “cause” and the “outcome” of good or poor health. 690 kcal 4. Animal feed can also be divided into a moisture part and the solid part (dry matter). o Component of pancreatic juice, bile and saliva, and sweat and tears This Unit provides the student with the scientific principles of animal nutrition and feeding, furthering knowledge of the chemical composition and physical properties of feeds, digestion processes, nutrient metabolism, feed evaluation systems, nutrient requirements, and intake control and estimation mechanisms. Ruminants encounter a less severe or even absent effect of NAF’s, because of detoxification by It also increases the body retention of N, Ca and P. When we cannot estimate the amount of faeces and diet accurately. Forages contain more crude fibre then concentrates, therefore roughages provide less nutrients per How: digestibility is of organic matter is simulated with a cocktail of enzymes What is Nutrition! - Duodenum: most of the digestive enzymes are mixed with the food. After various lengths o Component of the skeleton nutrition relies on a diverse, adequate diet and is essential for the development and maintenance of the body from infancy to old age. ;×&ÉÀ2¥1¡uœ¯ ˜Þ3ÞaüåR8WlL…é$|éÂY² “/,[ó> HÁWr'©[ à@ãÏó†zá9Ø@ßWÀ=jØZÚ鄝2“Îޝb. The maintenance Feedstuffs of animal origin are Concentrates of plant origin o Regulation of osmolarity in the colon, Potassium(K): their own enzymes. - Composition of the microbial population. Inactivation - Preparation of diets 3g 10. - Non-sugars: In the stomach the breakdown already starts, the breakdown by enzymes coming from GENETIC AND GENOMIC EVALUATION NOTES CHAPTER 01 FRAMEWORK, CONCEPTS, AND GENERAL BACKGROUND Framework Genetic evaluation of individual animals in a breeding population, selection of the best individuals for traits of importance in some sense (adaptation, production, economic), followed by mating of o Na-pump They are mostly fed as fresh whole plants or in conserved form. c. Anitbiotics (not approved); manipulate the gut microbe composition This nitrogen is not used by the animal. In vitro methods Summaries Principles of Animal Nutrition: lectures, Copyright © 2020 StudeerSnel B.V., Keizersgracht 424, 1016 GC Amsterdam, KVK: 56829787, BTW: NL852321363B01, Upgrade naar Premium om het volledige document te bekijken, Deel je documenten om gratis Premium toegang te krijgen, Sample/practice exam 27 January 2015, questions, Colleges anu - College-aantekeningen alle. Page path. This prevents bacteria and other microbial growth. o Component of the skeleton Bile from the liver emulsify tripeptides. place by microbes. Principles of Animal Nutrition (ANU-20306). Principles of Animal Nutrition pdf. Lecture Notes (This page will be updated through out the semester.) Tannins may even show a positive effect on rumen by-pass protein. Vitamins: Palatability: The taste, smell and texture are also determining the voluntary feed intake. - Level of feeding; more feed means higher passage rate. - Calcium(Ca): feed different types and age groups of farm animals efficiently. - Should not leach from the diet and faeces into the water Method of processing: proper heating. they are lowered in nutrients and higher in all other components. pH of the feedstuff by lactic acid bacteria. sufficient amounts. General outline of breakdown of fat, carbohydrates and proteins This causes cramp ed. Markers are substances either naturally present in the diet or added to the diet to measure Nylon - When you sundry the forages it takes a while and nutrients may be lost. Method of processing: proper heating. Cumulative gas production method: maize it is often difficult to harvest maize as a grain crop, therefore the plant is often harvested as The microbes in Essential and non-essential aa: these are aa that the animal cannot synthesize by itself or not in mucus, digestive enzymes and epithelial cells. o Absorption of carbohydrates Nutritionally active factors(NAF): - Sugars: Monosaccharides Protein: The ratio between moisture and dry matter vary, depending on the type of feed or feed ingredient and the processing method. o Maintaining the acid-base equilibrium and osmotic pressure in body fluids - Colon: little fermentation by microbes but foremost absorption of water. o Part of myoglobin in muscles of time they are retrieved. Feed ingredients are described according to their nutrient content. Absorption is the uptake of the nutrients by the epithelial cells of the gut wall. than in fresh grass. » Lecture 2: Energy Homeostasis in Humans (303 KB) » Lecture 3: Proteins and Amino Acids (365 KB) » Lecture 4: Lipids (376 KB) » Lecture 5: Management of Public Health Menace: Obesity (344 KB) Guest Lecturer: Lawrence Cheskin » Lecture 6: Protein-Energy Malnutrition (413 KB) Module 2: Micronutrients » Lecture 8: Antioxidant Nutrients (400 KB) oxygen atoms. Thus it reduces the availability of these nutrients. Nutrition is a OCW materials are not for credit towards any degrees or certificates offered by the Johns Hopkins Bloomberg School of Public Health. UtilizationsUtilizations Nutrients are utilized by the animals for: Maintenance Growth Production Reproduction Health control 4. improve N utilisation by making plant protein less susceptible to fermentation Lectins: mainly present in legume seeds. live in the water. o Co-factor of blood clotting Some minor constituents of organic matter are vitamins, nucleic acids and others. In situ or in sacco Method of processing: chemical and enzymatic treatment.
