Cow Calf Raising What is the importance of breed in the genetic Extensive (Ranching) strategy in beef cattle production? o Animals maintained in vast tracts of open land Matching applicable performance or functional levels o Usually leased from public lands to environmental, management, and marketing o Limited by agrarian reform and peace and order conditions. Integrated Farming Choosing a breeding system, either continuous (in o Utilizes small vacant lots or spaces between which replacement females are produced within the agricultural crops plantations herd) or terminal (in which replacements are o (shown: cattle farming integrated in a mango introduced externally); and farm) Selecting genetic types, breeds and individuals within the breeds that are compatible with the performance level needed and breeding system chosen Genetic Classification of Breeds Basic Classification o Bos taurus – European cattle o Bos indicus – Humped cattle (Zebu); arose in Intensive System south central Asia o Animals confined What is a breed? o Fed by cut-and-carry method o Animals of common origin with certain o Supplemental feeding with concentrates distinguishing characteristics passed uniformly from parent to offspring o Breed characteristics result from both natural B. Breeder Farm Operation selection and from that imposed by people Calves raised until ready for breeding then sold o “Composite” breeds are formed from two or Main output: quality breeder animals more breeds Utilizes purebred animals Large base needed for selection of replacement animals C. Growing-Fattening (Feedlot) Operation Raising of newly weaned calves or culled mature heifers to slaughter weight Requires simple facilities and level of management Growing stage (7-12 months of age) done extensively or intensively Fattening stage (5-7 months duration) done intensively  Functional Traits of Characteristics 8. Marbling (USDA Quality Grade) Important in Beef Production Intramuscular fat 1. Body Size Indicator of palatability factors of tenderness, Heavier at birth tend to be heavier throughout juiciness, and flavor life Increases with age up to physiological maturity Larger animals usually gain weight faster, and Higher in earlier maturing and higher milking weight and nutritional requirements for body types maintenance are closely related Yield is often inversely proportional to marbling Use the “Frame score” to objectively measure skeletal dimension used to estimate current and future body size 2. Milking Potential Genetic capability to produce milk (not actual volume) 3. Age at Puberty Smaller individuals and higher milking types usually mature earlier Bos indicus mature relatively late 4. Hot climate adaptability Bos indicus generally are more heat tolerant than Bos taurus (exceptions are present) Light colored, short hair coats and dark skin are most adapted High humidity - intensifies effects of heat, especially since hot, humid climates often add Selection (DA, Backyard Cattle Fattening) the stresses of parasites and low-quality forage. Age: 2-3 years old Heat with humidity - stresses cattle that fail to o Better FCE shed long, thick hair coats, particularly dark- o Have better digestive efficiency colored ones o Consume larger volume of feed in relation to 5. Fleshing ability body weight Capacity to fatten and retain fat Sex Tends to drop with increases in genetic body o Steers preferred over heifers size, maintenance requirements relative to size, o Readily available and easier to manage milking level, and inherent muscularity. o Gain weight and grow faster than heifers Poor environmental adaptability corelates with Breed – choose improved breeds and crossbreeds poor fleshing ability o Gain weight faster than native animals o Bos indicus tends to put on flesh faster in o Brahman, Ongole, Indu-Brazil, Batangas native poor quality forage cattle Easy-fleshing cattle tolerate periods of poor Health condition nutrition better leading to better reproduction o Alert and active, with bright eyes, smooth but tends to over fatten in feedlots haircoat and moist muzzle 6. Muscle expression Inherent muscularity independent of other Buy stock during the dry season (Jan-April) as they are tissues cheaper and transport from farms is more accessible Heavily muscled types are often low in fleshing ability 7. Cuttability (Dressing percentage; USDA Yield Grade) Percentage of lean Depends on relative amounts of fat, muscle and bone  Selection FACILITIES (Philippines Recommends for Beef Cattle Production) Basis for a single trait Animal Housing Animals own phenotypic merit (external features) o Important to animal health and productivity Pedigree information and collateral relatives o Containment o For early selection and sex-limited traits o Seperation or isolation Progeny testing o Protect from hazards o Based on performance of offspring Housing Considerations for Animal Health and Productivity Basis for selecting replacement breeders o Food and water access Comparable production records o Animal Spacing Physical characteristics o Ventilation Weaning weights of calves of respective dams o Lighting Weaning weights (at 8-months) and yearling weights o Comfort for bulls and heifers o Protection from hazards Weight and size at 2 years of age o Waste management o Social / behavioral aspects Specific measures of growth rates to monitor overall performance Housing - Cow Calf Operation o Smallhold farms – usually done using simple methods and facilities o Animals are usually tethered during the day and kept inside the shed during the night o The shed is built from native materials like wood and bamboo frames and enclosures; nipa and cogon for roofings o Space: 1.5 – 4.5 sqm per animal (2.1 – 2.7m width) ; height: 1.7 – 1.9m o Feeding and watering troughs can also be made out of locally available materials such as used tires, used and halved drums Housing – Fattening Operation o Animals are raised in individual stalls o 1.5m x 4m / head o Height three (3) meter high – to allow good ventilation o Feedlot may just be feeding pen  Housing – Fattening Operation Race o Materials: Bamboo, lumber, or ipil-ipil poles for Single passageway/pathway frames constructed to facilitate o Roofing: nipa or cogon ; galvanized iron roofing segregating animals may be used for durability May have a squeeze, dipping o Floor: concrete and sand should be used as vat, weighting scale, or loading flooring to prevent mud from accumulating and chute facilitate cleaning Fences Facilities in a race Purpose o Confinement o Prevent overgrazing / Rotational grazing o Separate / Distribute groups of animals o Fence-off poisonous plants o Shut-out stray animals Factors to consider o Movement of Race structures animals o System of grazing used o Size of herds o Natural Obstacles § Do not fence deep valleys Damaged by water, or Trampled by cattle moving down § Should run on top of ridge, not gully § Provide adequate space bet base and fence NUTRITION o Posts should be 5m apart and 1.5m above the ground Market Cattle Requirements o Top wire should be 1.4m above the ground Generally 2-3% of BW for DM intake o Other wires spaced 50, 50, and 40 cm o Actual intake: (DM% x BW) / DM content of feed) intervals on a 3 wire-strands fence o E.g., (400kg * 0.025) = 10kg DM required (2.5% expressed as decimals is 0.025) Handling Facilities o 10kg DM required / 0.3 = 33.33kg forages (30% Working Corral DM for forages with 70% moisture content) Reduce shrinkage CP – between 9 and 14% from sorting and Feedlot cattle average 12-14% handling cattle if TDN: 65-85% properly Calcium: 0.3-0.6% constructed Phosphorus: 0.2-0.4% Placed in the center o Considerably higher with byproducts of ranch operations Ca:P ratio of 2 (or greater): 1 to avoid urinary calculi Perferably on well-drained sandy soil Fences should be 168-184cm high using treated Maintenance baords (5cm x 5cm) Energy required to support basal metabolism, o Use coal tar or creosote maintain body temperature and normal activity to Posts should be 183 cm apart obtain food and water Place gates at corners Protein required to repair body tissues  Minerals are needed to replenish last ones Crude Protein Requirements Vitamins are essential in most metabolic activities Growth Growing Stage – rapid increase in muscle, bone, organs, and connective tissues Protein is the major nutrient required during the growing stage Energy required to support protein synthesis Mineral (Ca and P) required for bone formation Finishing – deposition of unused energy as fatty tissues Energy is required for the formation and deposition of fat Compensatory growth – increased weight gain following energy restriction FEED RESOURCES Reproduction Pastures Nutrient deficiencies before breeding result in Ranch type sterility, low fertility, and failure of pregnancy o Grasslands and cultivated pastures are primary Nutrient restrictions more damaging in late source of feeds pregnancy Smallholder Type o Protein restriction affect growth of fetus during o Primarily crop residues and weeds (due to limited the late stages of pregnancy pastures) o Ca and P requirements increase with stage of o Must take advantage of additional feed pregnancy resources in locality o Vit.
