ANIMAL NUTRITION CALCULATIONS: A. CO-EFFICIENT OF DIGESTIBILITY Example The moisture content of hay for cattle in a feedlot is 8%. A herd of beef weaners consumes 30 kg of the hay on average and excretes 12 kg dry manure every day. Refer to the information above and calculate the digestibility coefficient of the hay. Show ALL the calculations. 1st step- CONVERSION OF MOISTURE CONTENT ✓ 8%/100X30kg=2.4 kg moisture content 2nd step REMOVAL OF MOISTURE ✓ 30kg consumed -2.4kg moisture = 27.6kg Dry Matter Please note: The manure is already DRY, hence no need to remove moisture Co-efficient of digestibility= Dry matter intake – Dry matter excreted out x 100% Dry matter intake 3rd step Substitution Co efficient of digestibility = 27.6kg – 12kg x 100% 27.6kg = 57% Activity 1 1.1 A total of 2.5 kg of green Lucerne with a moisture content of 60% was given to an animal. The animal excreted 0,255 kg of dry matter in the faeces. 1.1.1 Determine the co-efficient of digestibility of the green Lucerne. (5) Page 2 of 88

ANIMAL PRODUCTION AND DISEASES Animal production protection and control SKILLS REPRESENTATION OF DATA Agricultural sciences contain a variety of scientific data that is often required by the learners to master and represent in their question papers. E.g. Line graphs, bar graphs, histograms and pie graphs. TABLE A table organizes and represents data clearly. It consists of a heading which gives a clear representation of the data. It may include a dependent and independent variable. What is an independent variable? An independent variable is the variable that you control and often changes during the investigation. A dependent variable is the variable that is affected by the independent variable. If written in columns and rows, the independent variable is usually in the left-hand side/ column, whilst the dependent is usually in the right –hand column. Example of a table Time (months) Milk yield (kg) 1 600 2 650 3 620 4 590 5 560 If a question states that the answer should be in table form, it must be given in table form. LINE GRAPH A line graph consists of both the independent and dependent values. It is a line showing the relationship between the two values. Things to be expected on a line graph: • Heading that has both the dependent and independent variables • X-axis (horizontal part ) represents the independent variables • Used for the quantitative aspects • Y-axis ( vertical part) represents the dependent variable • Values spaced at equal intervals • Should start at zero if there is a coordinate of zero • A correct scale must be used in drawing a graph Example of a line graph Weight gain in calves over time Page 9 of 88
14 12 10 8 Series 3 Series 2 6 Series 1 4 2 0 Category 1 Category 2 Category 3 Category 4 Bar graphs Bar graphs are used where the independent variable is qualitative (non –numerical) eg months, years, types of breeds and etc. it is often used for comparisons. In the bar graph the x- axis is the independent variable and is often qualitative/ non-numerical. The dependent variable (y-axis is quantitative/ numerical) • The x-axis is discontinuous so there are spaces between the blocks/bars • Width of bars must be consistent • Correct scale is to be used at all times Example of a bar graph (a compound bar graph) 6 5 4 Series 1 3 Series 2 Series 3 2 1 0 Category 1 Category 2 Category 3 Category 4 Page 10 of 88
HISTOGRAMS A histogram comprises of numerical data on a continuous scale on the independent x-axis, e.g. groups from 0-5,6-0,11-15 years etc. a histogram consists of: • Heading that includes both variables and the relationship between them. • X- axis represents the independent variable ( numerical values) • Y- axis represents the dependent variable (numerical data) • X-axis is continuous so there are no spaces between the blocks/bars/ columns • Blocks/bars / columns must be equal in width • Correct scale is to be used at all times. Example of a histogram ACTION VERBS Good understanding of the action verbs is essential to a learner in answering the questions provided.

B83 pathos 3.4 PAPER 2 Topic 1: Basic Genetics Did you know? A mind map is a diagram in which information is represented visually, usually with a central idea placed in the middle and associated ideas arranged around it. One can draw mind maps on every topic or sub-topic in Agricultural Sciences. See the Mind map of Basic Genetics on page » k Terminology In Basic Genetics it is very important to know the genetics terms in order to be able to do most of the questions. The following is a list of terms and their definitions in Basic Genetics: Allele -__variations of the same gene Atavism - reappearance of a characteristic in an organism after a period of absence Biometrics -__the use of statistics in biology Biotechnology the use of organisms to produce useful substances Breeding - process of producing plants or animals by sexual reproduction Cloning - aresearch activity that creates a copy of some biological entity (a gene/cell/organism) Dihybrid cross a genetic cross which involves 2 pairs of contrasting characteristics Dominant *« Co-dominance * Incomplete an allele that masks the effect of another & is expressed in the appearance of an individual type of inheritance where both alleles are dominant and fully expressed in the phenotype type of inheritance where both alleles are dominance partially expressed, often producing an intermediate characteristic. Epistasis - masking of the phenotypic effect of alleles at one gene by alleles of another gene Page 42 of 88

• Land is in a specific environment (land cannot be moved) • Production potential of land varies/ Production capacity varies / Production potential differs / production varies from area to area • Appreciates (its value increases overtime) • Value depends on location • Unlimited life expectancy • Can be bought and sold • It is collateral- (A valuable asset that is pledged to a lender to secure a loan. If the borrower defaults, ownership of the collateral transfers to the lender). ❖ THE TECHNIQUES/ METHODS OF INCREASING LAND PRODUCTIVITY • Improve water management/ water provision/ irrigation • Improve soil fertility • Education/ training • Changing farming practices • Adapt scientific methods of farming/ use of scientific methods/ used of technology • Consolidate small uneconomical land units/ consolidation of small units • Restoring land potential • Increase the size of gardens • Infrastructure • Diversification ❖ THE LAW OF DIMINISHING RETURNS o Yield/ production/ output will increase with an increase in input until optimum production is reached. o When the optimum production is reached the yield/ production/ output stabilise or remain constant o A further increase in input result in a decreasing in output/ production/ yield Page 56 of 88
❖ ADVANTAGES/ BENEFITS OF HAVING MACHINERY (or tractor) • Able to work on a large area faster • Use of machinery is more effective • More cost effective to produce ❖ PROBLEMS RELATED TO SOIL AS A PRODUCTION FACTOR • Law of diminishing returns • Physical condition of the soil • Soil limits the number of farming practices. 2. LABOUR: LABOUR: defined as physical and mental efforts/ skills provided in return for compensation ❖ BROAD CATEGORIES OF LABOUR • Skilled labour • Semi-skilled labour • Unskilled labour ❖ TYPES OF LABOUR/EMPLOYMENT • Permanent labour/ Fixed worker (Full-time): work 48 hour a week/ work ordinary hours set for the farming sector, -Sign a contract -Live permanently with their families on the farm -Employed on a permanent basis. -Enjoy certain privileges, e.g. permission to cultivate their own piece of land -Usually more proficient -A stable type of labour Page 57 of 88
-They do routine work on farm e.g. Skilled labour Example a foreman, Cultivate a field with a tractor Task: ➢ Feeding of stud rams ➢ Dosing of sheep ➢ Dipping ➢ Herding ➢ Inspection of watering points ➢ Counting of sheep and records • Part-time labour: work 2 days a week/ less than 48 hours per week/ work less than ordinary hours for the sector e.g. morning only • Temporal labour: Stand in for permanent/ they are employed for a specific task as the need arises. ➢ Shearing of sheep ➢ Upgrading of dams and watering troughs • Seasonal labour: work during peak periods such as during harvesting. -live elsewhere, employed seasonally during peak periods for repetitive tasks, such as; ➢ Harvesting/ harvesting period ➢ Planting/ planting period ➢ sheep shearing team • Casual labour: work less than 24 hours per month/ a week -live elsewhere, employed on a temporary basis for non-repetitive work such as; ➢ Building ➢ Erecting of a fence ➢ Construction of tunnels ❖ PROBLEMS ASSOCIATED WITH LABOUR IN AGRICULTURE THAT AFFECT LABOUR PRODUCTIVITY • Lack of skills/ limited education/ lack of training or education • Labour shortages/ scarcity/Shortage/ scarcity of labour • Industrial competition • Poor labour management Page 58 of 88
• HIV and AIDS/ Social • Theft / safety • Damage to expensive equipment/ damage infrastructure • High cost of labour • Irresponsible workers • Workers arriving late for work • Abuse of property • Competition from industries/ economic migrants • Poor working conditions ❖ LABOUR CHALLENGES/ CHALLENGES CAUSING LABOURS TO LEAVE THE AGRICULTURAL SECTOR • Law wages/ search for better wages/ opportunities • Lack of training/ unskilled labour • Low productivity • Long working hours • Competition • Unfavourable working conditions/ ill-health/ non-conducive working environment ❖ THE METHODS OF INCREASING LABOUR PRODUCTIVITY/ ADDRESSING CHALLENGES ASSOCIATED WITH LABOURS • Managing labour/ labour management/ Good management • Improve economic conditions of labourers or workers (by providing incentives for work, higher salaries, paying bonuses, providing insurance and pensions and give them farm products ) • Adequate living conditions/ improved living conditions/ improving work and living (adequate food, water and leave) • Addressing HIV and AIDS (organize AIDS awareness campaigns. Provide access to condoms. Supply vitamins and anti-retroviral medium) • Improving educational conditions (sending workers to trainings. Provide in-service training) • Ensure that labourers are trained/ skills development/ provide training/ education • Adherence to basic conditions of service • Provision of health education • Giving praise and recognition to labourers/ motivation • Provision of appropriate tools/ equipment/ cloths for the job • Improve on labour utilisation Page 59 of 88
• Rewards for good work • Improve working conditions • Remuneration • Proper planning must be done • Supervision must be done ❖ LABOUR LEGISLATION ACTS AFFECTING FARM WORKERS IN SOUTH AFRICA A. The labour relations Act-1995 ➢ Regulates the relationship between employer and employees and trade unions. Dismissal and labour disputes are dealt with. B. The basic conditions of employment Act-1997 ➢ Regulates working hours, overtime, night shift and payments of wages ➢ Intended to ensure that fair labour practices exist C. The occupational health and safety Act-1993 ➢ It deals with the safety in the workplace ➢ Aims to provide and regulate health/ safety in the work place ➢ Ensure that protective clothing is provided, gloves, footwear/gumboots, goggles/eye protection, dust masks, noise/ear protection D. The compensation for occupational injuries and diseases Act- 1993 ➢ It makes provision for payment of compensation for injuries or diseases contacted while employees are on duty ➢ Applies to employer/ employees who are injured, disabled or killed at work E.

CAPITAL CAPITAL: It is the money or equipment saved or accumulated by the farmer to use in the production process. OR it is the money or equipment employed in the production process. OR Is the wealth/money and goods accumulated through savings and is employed to start a business and in the production process. EXAMPLES: buildings, machinery, implements and money used in the agricultural production process. Assets: are the things the farmer owns that are of the financial value EXAMPLE: Land, machinery, buildings and livestock Categories of assets/ Types of assets 1. Tangible Assets (are any assets that have a physical presence. Examples include cash, stocks, bonds, property, buildings, equipment, inventory, precious metals and art) Page 61 of 88
2. Intangible Assets (are assets that have no physical presence. Examples include patents, copyrights, goodwill and trademarks. It is usually difficult to determine the value of intangible assets) 3. Financial Assets (is an asset that has a value that’s based on a contract. Examples include cash, stocks, bonds and derivatives) 4. Fixed assets (are long-lived assets that cannot be easily converted into cash. Examples include property, buildings, equipment and furniture) 5. Current Assets (include cash and assets that are expected to be converted into cash, consumed or expended in the next year or current operating period. Example fertilizers and seeds) ❖ TYPES OF CAPITAL I. FIXED CAPITAL: Involves fixed assets/ is the capital that is invested on things of permanent nature. EXAMPLES: o Land o Building o Fences o Dams o Pumps o Boreholes o Orchard II. MOVABLE CAPITAL: capital goods that can be moved from one place to another. OR is invested on medium term things EXAMPLES: o Tractors o Machinery o Equipment o Livestock o Implements III. PRODUCTION CAPITAL (working capital, floating capital): involves goods used in the production process. OR is short term capital. OR Capital used in the everyday operations of running the farming venture EXAMPLES: o Fuel o Spare parts o Seeds o Fertiliser Page 62 of 88
o Feed o Dip/ sprays o Wages o Salaries o Transport costs o Repairs o Contract work ❖ METHODS OF CREATING CAPITAL/ SOURCES OF CAPITAL / SOURCES OF FINANCE • Savings/ Own capital/ Individual’s own savings o Not paid with interest o Capital can be created though savings and investments • Production/ production and local market sales o Profit o The famer can increase production to accelerate the accumulation of capital • Credit/ loans/ loan capital o Require collateral (paid with interest) o Allow farmers to get goods or services before they pay for them. o Farmers can use credit to borrow money from financial institution but they must pay interest on the borrowed money • Grant o It is free ❖ SOURCES CREDIT / SOURCES OF CAPITAL WHERE THE FARMER CAN GET A LOAN OR SOURCES OF FINANCE WHERE THE FARMER CAN GET A LOAN • Commercial bank • Land bank/ Ithala bank • Trust company • Agricultural co-operatives • Business partner ❖ Normally fixed asset and movable assets act as collateral (The bank will only give credit when there is security, hence farm assets will act as security) ❖ THREE CLASSES OF CREDIT ✓ Long-term credit: -the interest rate is very low Page 63 of 88
-takes a long time to repay -have repayment periods of 10 to 35 years -the source for long-term credit is the LAND BANK -It is used for big capital goods such as: LAND, BUILDINGS, FENCES, PUMPS, BOREHOLES, and DAMS ✓ Medium-term credit: -the interest rate is relatively high -Have repayment period of 2 to 10 years -the source for medium-term credit is the AGRICULTURAL CO- OPERATIVES, NGO, AND COMMERCIAL BANK -UMOTHOMBO is an NGO that provides loans to sugar cane producers -it is used to buy movable capital: TRACTORS, MACHINERY, EQUIPMENT, and LIVESTOCK ✓ Short-term credit: -the interest rate is very high -have repayment period less than 2 years -the loans must be repaid within two years -the source for short-term credit is COMMERCIAL BANKS -It is used as working capital to buy goods for production process such as: SEEDS, PESTICIDES, FERTILISERS, SALARIES, WAGES, AND FUEL ❖ THE PROBLEMS ASSOCIATED WITH CAPITAL AS A PRODUCTION FACTOR • Scarcity of capital/ capital is scarce ➢ It is not easy to get capital ➢ Some capital goods cannot be manufactured in the country and must be imported ➢ Many financial institutions are reluctant to finance beginner farmers as they doubt their ability to repay the loan • Cost of capital ➢ The high cost of capital puts additional pressure on management to increase profits • High interest rate / High rate of interest ➢ The cost of acquiring and servicing borrowed capital is high and may increase at a rapid rate • Depreciation of capital/ Depreciation and loss Page 64 of 88
➢ Capital goods such as machinery, equipment and vehicles are subject to depreciation (reduction in value over time) and will have to be replaced. ➢ Machinery, equipment and vehicles can also be easily stolen • Over-capitalisation ➢ This situation prevails when the farmer spends too much money on capital goods than is necessary e.g. buying many types of ploughs when he only uses one at a time. The other ploughs lie idle and depreciate in value • Under-capitalisation ➢ This situation may prevail when the farmer does not have sufficient capital to produce the intended quantity of goods and may lead to losses and eventual failure of the business • Risk factor/ uncertainty ➢ Drastic changes in the climate resulted in a drop in the expected yield ❖ FINANCIAL MANAGEMENT SYSTEMS (Financial records, farm asset records, and farm budget) INCLUDES: o Keeping an inventory o Keeping cash analysis book o Preparing key financial statements () o Preparing budgets o Analysing financial results ➢ INVENTORY -Is the record of assets ➢ CASH ANALYSIS BOOK -used to record receipts and payments -Daily records summarised at the end of the month ➢ FINANCIAL STATEMENTS: Includes: 1.

• To analyse past and current performance • To plan for the future of the farm 4. MANAGEMENT MANAGEMENT: is the art of getting other people to do work in a co-ordinated effort. OR Involves planning how production will be organised and co-ordinated to achieve the set outcomes in the production process. Farm management: application of basic business principles and scientific principles of agriculture to the farm business Strategic management: management that allows the business to anticipate and adapt to changes in the future. /OR The process of developing strategies that allows a business to achieve its vision, mission, and objectives and adapt to changing conditions. Strategic farm risk management: involves developing objectives, a vision and mission, and developing business strategies. OR is a process designed to keep both the risks associated with the farm and the costs of running the farm to a minimum. NO RISK RISK MANAGEMENT STRATEGIES 1 Storm or hail damage Insurance against such damage 2 Animal diseases Animals should be adequately inoculated against any diseases 3 Crop diseases Care should be taken in choosing a cultivar that is disease resistant or alternatively ensure that plants get adequate protection against disease. 4 Damage to Motor Vehicles; a) Insurance may be taken Machinery and equipment b) Employees should be properly trained in the use of all machinery & equipment. 5 Injury to workers a) Workers should be properly trained and made aware of the various risks b) Insurance (workmen’s compensation) c) Medical Aid benefits 6 Strikes a) Management must be aware of all government regulations pertaining to the employment of farm workers.
