Download Exam 1 | ANSI 3653 - APPL ANIMAL NUTRITION and more Quizzes Zoology in PDF only on Docsity! TERM 1 Do Animals have feed or nutrient requirements? DEFINITION 1 Animals have requirements for nutrients and energy not for a specific feed. The feed is merely a carrier to supply the nutrients and energy that the animal needs. TERM 2 Nutrients required by animals? DEFINITION 2 WaterVitaminsMineralsCarbohydrateLipidsProteins TERM 3 Is energy a nutrient? DEFINITION 3 No energy is not a nutrient. Nutrients such as Carbohydrate, lipids and protein are converted into the energy needed to supply the body. TERM 4 Feed DEFINITION 4 Any material included in the diet or ration because of its nutrient composition and/or nutrient properties. TERM 5 Ration or diet DEFINITION 5 A 24-hr allowance of feed or mixture of feed ingredients TERM 6 Balanced ration or diet DEFINITION 6 implies that the ration or diet is nutritionally adequate to meet animal nutrient requirements for a specific purpose TERM 7 Concentrate DEFINITION 7 Any feed ingredient with low crude fiber and contains relatively high energy, protein, mineral, vitamin, or additive content. TERM 8 Roughage DEFINITION 8 any feed ingredient with greater than 20% crude fiber content and contains relatively low levels of nutrient density and typically is low in dry matter digestibility TERM 9 Maintenance DEFINITION 9 Condition in which an animal is neither gaining or losing body weight. TERM 10 When is an animal in a positive energy balance DEFINITION 10 When an animal is consuming more nutrients than required for maintenance and added production functions are supported. TERM 21 As Fed DEFINITION 21 Implies that "free water" is present in the feed TERM 22 Dry Matter DEFINITION 22 implies that "free water" has been removed through a mathematical calculation or removed through a drying process TERM 23 What nutrient component of livestock feeds is present in the highest amount on a dry matter basis? DEFINITION 23 Carbohydrates TERM 24 Principal Functions of Carbohydrates DEFINITION 24 Source of energy for bodily functionCarbon Skeletons for building other nutrientsMilk Synthesis TERM 25 Starch Linkage DEFINITION 25 Alpha 1 linkage that can be broken down by bacteria and digestive enzymes TERM 26 Cellulose linkage DEFINITION 26 Beta linkage of glucose that must be digested microorganisms in the rumen or the cecum of an animal TERM 27 What is unique about cellulose and starch digestion in the cecum of the horse? DEFINITION 27 Horses practice coprophagy (eating of fecal matter) because the primary site of absorption (small intestine) is past the primary site of digestion (Cecum). TERM 28 3 Principal Volatile Fatty Acids DEFINITION 28 Propionic AcidAcetic AcidButyric Acid TERM 29 Nutrient Found in the highest concentrate DEFINITION 29 Protein TERM 30 Dietary Essential Amino Acid DEFINITION 30 Amino Acids required in the diet and cannot be synthesized at a rate sufficient to meet the nutritional requirements of the animal. TERM 31 Name the Dietary Essential Amino Acids DEFINITION 31 PhenylalanineValineThreonineTryptophanIsoleucineMethionineHistidineArginineLeucineLysine TERM 32 4 Most limiting Essential Amino Acids DEFINITION 32 ThreonineTryptophanMethionineLysine TERM 33 1st Limiting Amino Acid DEFINITION 33 The essential amino acid that is present in the lowest quantity in the diet when expressed as a percentage of the animals amino acid requirement TERM 34 Non-ruminant Essential Amino Acid DEFINITION 34 Processed in the cecum by billions of microorganism TERM 35 Ruminant Essential Amino Acid DEFINITION 35 Processed in the rumen by billions of microorganisms TERM 46 3 Essential Fatty Acids DEFINITION 46 LinoleicLinolenicArachidonic TERM 47 Functions of lipids DEFINITION 47 Dietary energy sourcesource of essential fatty acidsInsulationcarrier of fat soluble vitaminsMajor factor in quality grading of beef TERM 48 Fat deposition in body DEFINITION 48 InternalIntermuscularSubcutaneousIntramuscular TERM 49 Lipid Feed Application DEFINITION 49 Increase energy content of dietControl dustBind small particlesMaintenance of equipment TERM 50 Major functions of minerals DEFINITION 50 Growth and development of bones, teeth, and soft tissueRegulation of cell acid:base balanceComponent of enzymesRegulation of body properties TERM 51 Absorption of inorganic trace minerals DEFINITION 51 Sulfates: 70-75% absorptionOxides: 20-25% absorption TERM 52 Absorption of organic trace minerals DEFINITION 52 100% absorption TERM 53 Proximate Analysis (Weende System) DEFINITION 53 Procedures to estimate nutrient components of feeds TERM 54 What analysis is not determined by chemical analysis? DEFINITION 54 Crude Protein100g Protein/ 16g Nitrogen=6.25 TERM 55 Why 6.25 is used to determine Crude Protein DEFINITION 55 Protein contains on average of 16% Nitrogen by molecular weight TERM 56 What does Ether Extract value determine DEFINITION 56 Measurement of lipid content TERM 57 What does percent Ash determine DEFINITION 57 Measurement of minerals in the feed TERM 58 Crude fiber vs. Nitrogen Free Extract DEFINITION 58 Crude fiber- estimates less digestible carbohydrate fractionNitrogen Free-extract: Estimates non-fibrous carbohydrates TERM 59 Neutral Detergent Fiber DEFINITION 59 Neutral Detergent Fiber is the most common measure of fiber used for animal feed analysis, but it does not represent a unique class of chemical compounds. TERM 60 Acid Detergent Fiber DEFINITION 60 Predict digestibility of forage by animals TERM 71 Positive associative effect DEFINITION 71 consumption of one feed will result an increase in the consumption of another feed TERM 72 Negative associative effect DEFINITION 72 Consumption of one feed will result a decrease in the consumption of another feed TERM 73 What must be on a feed tag that contains medicated feed? DEFINITION 73 Must say "Medicated" statement of purpose or claim active drug ingredient amount in the feed TERM 74 Required guaranteed feed analysis DEFINITION 74 Min Crude Protein Max Crude Protein Equivalent from Non Protein Nitrogen Min Crude Fat (Ether Extract) Max Crude Fiber TERM 75 How are feed ingredients listed? DEFINITION 75 Listed in order of largest percentage in the ration to smallest percentage in the ration TERM 76 Custom Mix DEFINITION 76 Feed mixed just for you by the feed company and can only be sold to you.
