1 AA22 Animal Science II Unit C Animal Management Essential Standard 5.00: Understand management of agriculture animals. Objective 5.01: Classify animal housing, facilities and waste management

2 Beef Housing and Facilities A. Types of Operations- producers should plan facilities and equipment to suit the various types of beef operation(s). 1. Cow-Calf Producers- a herd of cows are bred each year to produce calves. Calves are usually sold at 6months to 1 yr of age. 2. Seedstock- also known as purebred breeders. Keeps herds of registered stock 3. Cattle Feeders i. Stocker Operations- purchase calves from cow-calf ii. producers. Feedlot- raise animals to finished weight.

3 B. Types of Housing 1. Confinement Barns i. Cold- opens to environment on one side. a. Uses a pole-type building with an open-span structure to make it easier to remove waste. b. Can use various solid bedded or slotted floors. 2. Warm- closed, insulated and kept warm. a. Most expensive type of facility. b. Used in colder climates. c. Can use solid bedded, slotted or solid flushing floor systems.

4 2. Open Feedlot- no buildings, just windbreak fences and sunshades to protect from wind, snow, and sun. i. Unpaved floors with some concrete around feeding and watering stations. ii. Requires more land area. iii. Floors are typically dirt, therefore drainage and runoff controls are important.

6 3. Open Barn and Feedlot- open front barn and feedlot. i. Provides protection from environmental elements. ii. Used in Midwestern part of United States. iii. Unpaved floors with some concrete around feeding and watering stations.

7 4. Feeding Barn and Lot- same system as open barn and feedlot except feed bunks are located in the barn.

8 5. Pasture- typically used for cow-calf producers and requires minimal facilities. i. Important to manage pastures to maximize growth potential of forages, distribute manure and control parasites. Methods include: a. Pasture Rotation- cycles animals through a series of pastures. b. Strip Grazing- providing animals with smaller sections of grass every few days. Maximizes forage growth and land utilization, but requires more labor.

9 C. Beef Operation Considerations 1. Number of Cattle- determined by the resources available and the type of operation.

10 2. Amount of Land- varies depending on operation. General guidelines: i. Feedlots- 5 acres for every 500 head of cattle. ii. Partial Confinement & Pasture- depends of location of facilities, pasture management, age of animals, etc.

11 3. Location and Environmental Factors i. Easy access to roads. ii. Space for expansion. iii. Movement of cattle. iv. Environmental Considerations- odor, wind, dust, runoff.

12 4. Feed Storage and Handling- systems vary depending on type of facilities. 5. Money and Labor i. Input costs to build and maintain facilities. ii. Labor supply.

13 D. Beef Cattle Equipment 1. Corrals- needed for all types of beef cattle enterprises. i. Parts Include a. Holding Pen- first system cattle are moved into from a larger open area such as a pasture or feedlot. b. Sorting Pen- workers can separate cattle into smaller groups than holding pen. c. Working Chute- usually includes a crowding pen that again moves cattle into a smaller group. Cattle are then moved into an alleyway system where they are funneled from the crowding pen into an individual line. d. Headgate- holds cattle so worker can perform preventative maintenance or treat injury/illness.

14

15 ii. Advantages: a. Easier to handle cattle. b. Reduces labor. c. Saves time. d. Safety of workers and animals. e. Reduces stress on animals.

16 Dairy Housing and Facilities A. Types of Operations 1. Intensive Dairy Production- animal raised in a more confined setting such as an open lot or tie stall barn. 2. Pasture Dairy Production.- cattle are turned out on pasture continuously or for portions of the day.

17 B. Types of Housing 1. Stall Barns- cows confined to a stanchion or tie stall. i. Structure at the front of stall usually serves as feed ii. bunk with an automated watering system. Waste removed in center aisle by motorized or automated equipment.

18 2. Free Stall Barn- cows maneuver throughout barn. i. Stalls are a bedded area for cattle to rest. ii. Facility may be fully or partially enclosed and temperature regulated. iii. Floors may be dirt, solid concrete or slatted. iv. Waste removed by motorized equipment.

19 3. Pasture i. Cows kept on pasture continuously or for portions of the day. ii. Producers often use a combination of pasture and some type of barn facility. iii. Replacement heifers are often raised on pasture.

20 4. Portable Hutches- used to house young calves. 5. Heifer Barns- used to house replacement heifers after portable hutches. Animals can be grouped in pens or in individual stalls.

21 C. Dairy Operation Considerations Same as beef considerations.

22 D. Dairy Cattle Equipment 1. Headlocks- modified headgate system where larger numbers of cattle can be restrained. i. Typically attached to feed bunks so animals are ii. accustomed putting head into latch system. Routine veterinary care and reproductive related procedures are usually administered in headlocks.

23 2. Headgate and Working Chute- same system as what is used for beef cattle. Used for more intensive veterinary procedures and hoof trimming.

24 3. Milking Equipment i. Milking Parlors- separate room/area where cattle are milked. a. Most common method of milking cows. b. Includes a pit where workers operate equipment used to milk animals. c. Most common milking parlor design is the herringbone.

25 4. Milkhouse- room where milk is filtered, cooled and stored in stainless steel tanks.

26 Swine Housing and Facilities A. Types of Operations- producers plan facilities based on type on type of operation. 1. Sow- maintains sows for breeding, gestation and farrowing. Manage piglets until weaning. 2. Nursery manage piglets from weaning until approximately 50lbs. 3. Grow-Finish- manage barrows and gilts until they are ready for market. 4. Farrow-to-Finish- manage groups of sows and piglets all the way to market weight.

27 B. Types of Housing 1. Pasture or outdoor without climate controlled buildings. 2. Confinement Houses i. Cold- may be open on one or more sides. Used ii. mainly for finishing hogs. Warm- controls temperature, moisture, odor and airborne diseases through a ventilation system. Used mainly for breeding, farrowing and young pigs. 3. Most North Carolina swine operations use warm confinement houses.

29 C. Swine Operation Considerations 1. Location and Environmental Considerations i. Odor is a major problem with swine facilities. ii. Access to roads, power and water.

30 2. Proximity- swine operations are highly vertically integrated. Need to be in an area that has other operations of similar type in order to secure a contract with a company. 3. Regulations i. Some areas have restriction on the construction of ii. new facilities. Special waste management considerations are also a factor.

31 4. Feed Storage and Handling- confinement facilities typically use feed/grain bins to store feed. 5. Money and Labor i. Input costs to build and maintain facilities. ii. Labor supply.

32 D. Swine Equipment 1. Feeding and Watering Systems- many confinement swine facilities have automatic feeding and watering systems. i. Automatic feeding and watering are more ii. expensive, but they save on labor. Hand or non-automatic systems cost less, but require more labor.

33 2. Floors i. Solid- usually made of concrete. ii. Partially Slotted- a portion of the floor is slotted with another section being solid. iii. Totally Slotted- entire floor is slotted to allow for continuous removal of waste.

34 3. Farrowing hog enterprises require small equipment such as castrating knives, ear notchers, and needle teeth clippers. i. Gestation Crates/Stalls- animals spend 24 hours a ii. day in crate during gestation period. Allows producers to meet specific nutritional needs of each animal and removes potential for injury from other aggressive sows. iii. Very controversial method or housing pregnant animals. Many larger companies are phasing out the use of gestation crates and moving to a group housing system where animals can go into individual pens if they choose, but can also come out to move and socialize with other females.

39 Poultry Housing and Facilities A. Types of Operations 1. Egg Production- produces eggs for human consumption. 2. Broiler Production- poultry produced for meat consumption. 3. Replacement Pullet Production- raising chickens to replace either egg or broiler production operations. 4. Egg Hatcheries- hatch eggs.

40 B. Types of Housing 1. Confinement Houses- clear span structure with insulated ceiling and walls to prevent heat stress. Ventilation is a key consideration in building design. i. Broilers and Turkeys a. Usually have dirt floors covered with wood shavings or straw. b. Lights are on 24 hours a day.

41 ii. Laying Flocks a. Use wire cages to save space and to have cleaner eggs. b. Artificial light controlled by timers are used because laying hens require at least 14 hours of light per day.

42 iii. Replacement Pullets a. Laying pullets may be raised in cages for brooding or until moved to laying houses. b. Broiler breeder pullets are raised in confinement houses on dirt floors. c. Lights are controlled to regulate sexual maturity and egg production.

43 2. Range or Outside Structures- some turkeys and chickens are grown on range or outside, but the trend is away from this method because of land requirements, diseases, predators and weather. Popular method of housing poultry raised by small scale or niche producers. 3. Egg Hatcheries- buildings located separately from production facilities. Include large scale incubators to hatch eggs and equipment to process, sort and transport chicks in preparation for shipment to a production facility.

45 C. Poultry Operation Considerations 1. Location and Environmental Considerations i. Access to roads, electricity, water. ii. Odor, waste management and mortality management. 2. Proximity- poultry operations are highly vertically integrated. Need to be in an area that has other operations of similar type in order to secure a contract with a company.

46 3. Feed Storage and Handling- confinement facilities typically use feed/grain bins to store feed. 4. Money and Labor i. Input costs to build and maintain facilities. ii. Labor supply.

47 D. Poultry Equipment 1. Brooders- using infrared heat lamps to keep young chicks at optimal temperature. i. Chicks are typically brooded on the floor in a ii. section of the poultry house. Uses a hover guard to keep chicks from wandering away from heat source.

48 iii. Optimum temperature for chicks is degrees Fahrenheit. Temperature is reduced 5 degrees per week until reaches degrees Fahrenheit. iv. Take temperature 3 from floor to obtain accurate temperature for chicks.

49 2. Feeding and Watering Systems- highly automated in both all types of poultry houses.

50 Animal Waste Management Regulations A. Confined Animal Feeding Operations (CAFO)- used to describe operations that raise large numbers of animals in a confined setting. B. It is a violation of state law for waste to reach surface water.

51 C. A $10,000 per day penalty may be assessed if there is a man-made conveyance such as a pipe or a ditch to route waste away from a holding pit or lagoon even if no waste is actually discharged. D. It is against the law for anyone to cause a water quality standard violation.

52 E. Senate Bill mandates the number of animals that require a waste management plan and permit. i. 250 or more swine. ii. 100 or more confined cattle. iii. 75 or more horses. iv. 1,000 or more sheep. v. 30,000 or more confined poultry.

53 F. Animal waste management system operators must be certified. G. In addition to state regulations, local county and city regulations such as zoning and facility locations also apply. H. In addition to fines and lawsuits brought by governmental agencies, third-party lawsuits can be bought by individuals or organizations against livestock and poultry operations.

54 I. It is easier to prevent animal waste problems than to correct them. J. Types of Waste Management Systems 1. Type A Systems- primarily rely on anaerobic lagoon and soil/plant systems for the treatment of animal wastes with low fiber such as swine and poultry. 2. Type B Systems- primarily rely on soil/plant systems for the treatment of animal waste with high-fiber such as cattle, horses, and sheep.

55 K. Components of a North Carolina Animal Waste Management Plan 1. Odor Control- from decomposing manure, feed, and carcasses 2. Insect Control- eliminates or reduces causes of insects and uses approved materials to control. 3. Animal Mortality- approved methods to quickly dispose of dead animals.

56 4. Riparian Buffers- vegetative buffers. 5. Waste and Soil Testing- both the animal waste and the soil on which it is applied must be tested. 6. Record Keeping- must be done to include soil and waste analysis reports as well as land application dates and rates for each application site. 7. Waste Application Rates- follow the waste utilization plan. 8. Emergency Management- plan to manage disasters from flood, fire, disease, etc.

57 L. Components of a Waste Utilization Plan 1. Source of nutrients. 2. Amount of nutrients. 3. Placement of nutrients. 4. Timing of nutrient applications.

58 M. Best Management Practices- methods that reduce the loss of nutrients thereby reducing the potential for negative environmental impact. Examples: 1. Buffers- distances from streams, homes, or property lines.

59 2. Grassed Waterways- natural or constructed water runoff. Helps control erosion.

60 3. Conservation Tillage- using a no till drill so soil surface is not disturbed.

61 3. Strip Cropping- growing alternating crops in strips that follow the contour of the land.

62 5. Contour Planting- planting across a slope while following the contour of the land. 6. Crop Residue Management- any tillage method that leaves crop residue.

63 7. Coastal Bermuda grass is used on much land where animal waste is applied because it removes high amounts of nutrients from the soil as well as controls erosion.

64 Student Project Assignment Group members will create a preventative maintenance schedule for their farm for an entire calendar year. All animals were purchased on December 31 st. Therefore maintenance schedules begin January 1 st. Projects are presented on PowerPoint with each month specifying maintenance procedures for each group of animals Ex: January Calves Brood Cows Steers/Slaughter Animals

65 Maintenance schedule must include: 1. Vaccinations- Cost per animal When and how administered What disease your preventing 2.Parasite Control- Cost When and What Product Status consideration- pregnant versus open 3.General Maintenance- depends of livestock Castration/Docking Hoof Care Weaning Stress Management
