- This was 14.5% higher than PhP128.01 per kg (liveweight) in 2020.
- The highest average farmgate price during the 2nd quarter of 2021 was PhP147.28 per kg (liveweight) in May.
- The lowest price was PhP145.48 per kg (liveweight) in April.
Chapter 1. Overview of the Beef Cattle Industry
- The Philippines beef cattle industry has 3 major systems: Ranching, Feedlot and Backyard.
Inventory
- 2019: Backyard = 6.0% , Commercial = 94.0%, Total =6.0m heads
- 2020: Backyard = 6.0% , Commercial = 94.0%, Total =6.0m heads
- 2021: Backyard = 5.3% , Commercial = 94.7%, Total =2.59m heads
- 2021 Growth Rate: Backyard = 0.5%, Commercial = -11.1%, Total = -0.2%
Population
-
The factors contributing to the accomplishment of the goal are:
- Early sexual maturity of females
- High conception rate
- High calf crop
- Early rebreeding after calving
- Excellent milk production of the cows
- Availability of year-round feed supply
- High quality of management, profile of nutrition, and farm infrastructures
There are 5 major regions by population:

- Abundant availability of crop residues, especially in small farms.
- Favorable climate for fodder production.
- Availability of cattle production and meat processing technologies for increased productivity.
Constraints
- Low breeding base.
- High financing costs for breeder operations.
- High cost of inputs.
- Lack of infrastructure.
- Competition for land use.
- Changing policy guidelines (e.g. pasture lease, tariffs)
- Import substitutes (e.g., carabeef).
- Policy to unify and integrate the beef industry.
Interventions (Needed)
- Build up population base through well-defined breeding programs.
- Increase animal productivity through improved husbandry practices and biotechnology application.
- Promote appropriate feeding and encourage utilization of non-conventional feedstuffs.
- Implement strict quarantine procedures and efficient disease control/eradication programs.
- Improve marketing and pricing systems.
- Review policies on importation and credit systems.
Chapter 2. Beef Production Systems in the Philippines
Beef Production Systems
- Ranching or extensive system.
- Feedlot fattening.
- Backyard/small-holder/semi-subsistence.
Ranching or Extensive System
Cow-calf operation
- Uses grade or Philippine cows and purebred bulls.
- Involves selling calves at weaning as stockers; feeder stocks after grazing; fat slaughter cattle after feeding; or selling heifers for breeding.
- Relies heavily on native pastures with minimal supplemental feeds (concentrates).
- Can be integrated with orchards or coconut plantations.
Breeder farm operation
- Highly specialized using purebred cows and bulls.
- Requires large capital for animals and equipment.
- Requires skilled managers with experience in feeding and salesmanship.
- Aims for highest quality cattle for the open market.
Feedlot Fattening Operation
- Important for farmers to generate extra income.
- Allows year-round work using cheap, plentiful farm by-products (e.g. corn stovers, hay, silage, rice straw, copra meal, rice bran, sugarcane tops)
- Helps meet demand for high-protein foods.
- Properly fattened cattle is in great demand; but feedlot cattle operations popular only in Batangas, Tarlac, and Pangasinan, few ops in other parts.
- Majority of operations are small-scale, fattening 2-3 heads at a time.
Backyard Cattle Raising
- 92% of the total cattle population is from backyard.
- The aggregate share of top five regions (Ilocos, Southern Tagalog, Central Visayas, Northern Mindanao, and Davao Region) account for 56.9% of the total population.
- The aim is to produce livestock that can be sold to augment farm income.
- Typically, 1-2 heads of either fattening or breeding cattle is raised in spare time.
- Farmers usually tether animals to graze and supplement the diet with farm wastes (e.g. rice straw, corn stovers/stalks).
- Some practice soiling and supplementing (e.g. ipil-ipil, rice bran, corn bran, copra meal) at 1-2 kg/animal.
- In Batangas, force feeding (supa or supak) of mixed feed is common practice among backyard cattle raisers.
Chapter 3. Beef Cattle Breeds, Breeding, and Reproduction
Breeds from Great Britain
- Hereford: one of the first breeds developed in England, distinguished by its white face, white flanks, white tails and white neck crest. The body color ranges from cherry to mahogany red. A popular choice for polled trait.
- Angus: naturally polled and solid black or red; noted for high quality meat, increased weight gains. An abdominal spot of white is common.
- Aberdeen Angus: a popular solid black Angus with an abdominal white spot.
- Red Angus: a solid red Angus.
- Shorthorn: dual-purpose breed suitable for both dairy and beef production. Colors are red, white or roan; completely white is uncommon.
- Galloway: among the oldest breeds in the world, noted for its long, thick coats, common for regions with cold climates. Colors include white/red/roan.
- Belted Gallorvay: Similar to the Galloway, but recognized by a black belted coat.

- Cull heifers that don't come into heat on time, don't meet standard breeding herd.
- Cull bulls and cows with undesirable hereditary traits(inverted teats, hernia, dwarfism)
Chapter 7: Animal Health Program
Herd Health Management
- Responsibility and care for disease control for veterinarians and livestock raisers.
- Requires due consideration to local conditions and resources.
- Disease rates and production may be a result of low conception rate,high pre- & post-weaning mortality, and annual deaths in mature cattle.
Disease Prevention Measures
- Start with healthy stocks. Purchase healthy animals from trustworthy sources and isolate for 30 days.
- Deworm, detick, and immunize during isolation.
- For unconfined herds: maintain proper application of preventative health measures consistently. In areas with high liverfluke incidence, de-worm with flukecide ever 3-4 months to control this disease.
- Provide adequate nutritive rations to improve livestock resistance and health.
- Maintain clean, safe housing for animals with clean water supplies to mitigate environmental stress.
- Practice proper sanitation to minimize waste and pest build up and prevent disease spread.
- Graze animals in pastures free from internal parasites like liverfluke; use flukecide as control.
- Deworm often with effective parasite treatments, especially in areas with a high risk for parasites transmission.
- Control ticks with correct amount of chemical treatment.
- Cull breeding stocks that are unproductive, replace with tested breeders.
- Conduct frequent fecal examination to check parasitic presence and increase monitoring of incidence.
- During disease outbreaks, isolate the sick/ill animal immediately and allow immediate veterinary treatment. Strengthen environmental control measures(i.e., sanitation and disinfection)
- Arrange community vaccination programs with local authorities when needed. 14.Segregate from other animals (carabaos, goats, sheep) to reduce possible infection transmission.
Herd Health Program
- Before breeding: select breeders with good genetic makeup, blood test for diseases like brucellosis and leptospirosis; deworm with wide-spectrum anthelmintics; inject with vitamin ADE; vaccinate against diseases in the area (FMD, hemorrhagic septicemia, blackleg, brucellosis, anthrax) before breeding.
- During pregnancy: provide adequate nutrition (minerals, vitamins), possibly inject vitamin ADE in the second/third trimester; immunize against bacterial diseases (Salmonella, Pasteurella, Leptospira) at 7-8 months; deworm against intestinal roundworms in the last couple of weeks.
- During calving and post-calving: separate expectant cows from herd a week before calving; prepare clean calving areas; apply iodine on umbilical stumps of calves; treat dames with antibiotics to prevent uterine infections; repeat deworming to prevent gastro-intestinal parasites at 2-3 months, and again before weaning; move calves to pasture areas or corrals suitable for their separation from dams.
- During yearling and growing period: repeat vaccinations when immunity from previous vaccinations have waned; repeat tick control frequently; treat against liverflukes in areas where prevalent; consult a veterinarian for treatment if disease outbreaks occur.
