Performance of Philippines Agriculture (Q2 2021) for the second
quarter of 2021 (Growth Rates, at Constant 2018 Prices)
o Crops Both positive (56.2%)
o Livestock Both Negative (14.2%)
o Poultry Negative, Positive (13.5%)
o Fisheries Positive, Negative (16.1%)
Uses of Animals
o Food Eggs, Milk, Baking, Fried Chicken, these are all
demanding, animals provide us with food.
o Employment
Know that the animals do not hire us.
Animal husbandry requires a lot of people for their
work force.
o Work The animals can be used for work like plowing the
field, carrying heavy load that is for animals’ work.
o Clothing Imagine goose feathers, fur clothing, and the skin
of animals can be used for our clothing articles.
o Fertilizer Usually the manure of animals is being used for
fertilizer and they are very good at it.
o Companionship For those who have pets can relate to the
use of animals in terms of this, they provide good
companion, they are dependent on you but they give back,
so for those who don’t have pets, you might want to try it.
o Entertainment Who among you watches TikTok for
example Hammy the corgi and Olivia.
o Research
Animals are being used for research.
Pigs
The most notable because they have the same
cardiovascular and digestive system form as of the
humans.
That is why human research is being conducted
with pigs.
Lab Rats or Rodents
Monkeys
Problems with the Animal Industry
o Insufficient/unstable supply of feeds During Philippines’
storms season, most of the corn and rice are being imported,
and the supply fluctuate may also be high. It is difficult to
supply raw materials that are actually dry during the time.
o Presence of man diseases In our country, previously, we
had Avian Influenza, African Swine Fever, Rabies, and many
more.
o Frequent climatic disturbances
This is related to insufficient/unstable supply of feed.
For example, an investor puts PHP150, 000 on a
broiler growing enterprise, usually investors tend to
be positive in making a return of their investments, in
comes typhoon which will flatten down the whole
thing, and therefore the investment will go down.
o Lack of finances Example is if you are going for a Broiler
Production Enterprise, PHP 150, 000 will only just cover the
rent and water, but not the manpower.
o Slow transfer of technology Our country an island nation,
the transfer of technology is quite a problem. Yes, we have
internet and new ways to transfer technology, current
technological designs are better. But for example, you
manufacture a machine in Luzon, and you have to bring it to

Animal Production

The Animal Production o https://www.youtube.com/watch?v=Ii-8_PPXy Lecture introduction to some of the principles of animal production

  • Performance of Philippines Agriculture (Q2 2021) for the second quarter of 2021 (Growth Rates, at Constant 2018 Prices) o Crops – Both positive (56.2%) o Livestock – Both Negative (14.2%) o Poultry – Negative, Positive (13.5%) o Fisheries – Positive, Negative (16.1%)
  • Uses of Animals o Food – Eggs, Milk, Baking, Fried Chicken, these are all demanding, animals provide us with food. o Employment ▪ Know that the animals do not hire us. ▪ Animal husbandry requires a lot of people for their work force. o Work – The animals can be used for work like plowing the field, carrying heavy load that is for animals’ work. o Clothing – Imagine goose feathers, fur clothing, and the skin of animals can be used for our clothing articles. o Fertilizer – Usually the manure of animals is being used for fertilizer and they are very good at it. o Companionship – For those who have pets can relate to the use of animals in terms of this, they provide good companion, they are dependent on you but they give back, so for those who don’t have pets, you might want to try it. o Entertainment – Who among you watches TikTok for example Hammy the corgi and Olivia. o Research ▪ Animals are being used for research. ▪ Pigs
  • The most notable because they have the same cardiovascular and digestive system form as of the humans.
  • That is why human research is being conducted with pigs. ▪ Lab Rats or Rodents ▪ Monkeys
  • Problems with the Animal Industry o Insufficient/unstable supply of feeds – During Philippines’ storms season, most of the corn and rice are being imported, and the supply fluctuate may also be high. It is difficult to supply raw materials that are actually dry during the time. o Presence of man diseases – In our country, previously, we had Avian Influenza, African Swine Fever, Rabies, and many more. o Frequent climatic disturbances ▪ This is related to insufficient/unstable supply of feed. ▪ For example, an investor puts PHP150, 000 on a broiler growing enterprise, usually investors tend to be positive in making a return of their investments, in comes typhoon which will flatten down the whole thing, and therefore the investment will go down. o Lack of finances – Example is if you are going for a Broiler Production Enterprise, PHP 150, 000 will only just cover the rent and water, but not the manpower. o Slow transfer of technology – Our country an island nation, the transfer of technology is quite a problem. Yes, we have internet and new ways to transfer technology, current technological designs are better. But for example, you manufacture a machine in Luzon, and you have to bring it to

Mindanao, it will be too big, and you have to fair it out for transport, therefore the contribution of slow transfer of technology. o Prevalent poor management practices – Related to lack of technical knowledge, example is our government, who should address our framers with technical knowledge. o Records – Keep accurate records for accurate reports for the growth of the year, to gage efficiency in production. o Adaptability problems of animals (diary) – In our tropical country, some of the diaries are not able to adapt, and even if they produce milk like in their home country. The problem is our climate and temperature which affects their performance. Body sex of animals also contributes to production. o Long lead-in period and high investment (Large Animals) – Lead-in period is the time elapses from the time you place your order until the order actually gets delivered to you. And we have a long lead-in period here in the Philippines. o Lack of technical knowledge

  • Animal Science o Is concerned with the science and business of producing domestic livestock species, including but not limited to: ▪ Beef Cattle ▪ Dairy Cattle ▪ Horses ▪ Poultry ▪ Sheep ▪ Goat ▪ Swine ▪ Bee (Health and Production) ▪ Rabbit o Includes every aspect from: ▪ Conception to death ▪ Behavior and management ▪ Physiology to psychology, and ▪ Reproduction to product distribution o Concern with food of animal origin: ▪ Meat ▪ Diary Food, and ▪ Eggs o Concerned with aspects of companion animals, including their nutrition, care, and welfare.
  • Animal Scientist o Applies principles of the biological, physical, and social sciences to the problems associated with livestock production and management.
  • Basic freedoms of animals o Freedom from thirst, hunger and malnutrition o Freedom from physical discomfort and pain o Freedom from injury and disease o Freedom to conform to essential behavior patterns o Freedom from fear and distress
  • Republic Act No. 8485 o An act to promote animal welfare in the Philippines o “The Animal Welfare Act of 1998”
  • Section 1 o It is the purpose of this act to protect and promote the welfare of all terrestrial, aquatic and marine animals in the Philippines by supervising and regulating the establishment and operations of all faculties utilized for breeding, maintaining, keeping, treating or training of all animals either as objects of trade or as household pets. For this purpose of this Act, pet animal shall include birds.
  • Section 2 o No person, association, partnership, corporation, cooperative or any government agency or instrumentality including slaughter houses shall establish, maintain and operate any pet shop, kennel, veterinary clinic, veterinary hospital, stockyard, corral, stud farm or stock farm or zoo for the breeding, treatment, sale or trading, or training of animals without first securing from the Bureau of Animal Industry a certificate of registration therefore.
  • Section 3 o The director of the Bureau of Animal Industry shall supervise and regulate the establishment, operation and maintenance of pet shops, kennels, veterinary clinics, veterinary hospitals, stockyards, corrals, stud farms and zoos and any other for or structure for the confinement of animals where they are bred, treated, maintained, or kept either for sale or trade or for training as well as the transport of such animals in any form of public or private transportation facility in order to provide maximum comfort while in transit and minimize if not totally eradicate, incidence of sickness and death and prevent any cruelty from being inflicted upon the animals.
  • Section 4

o Abandonment means the relinquishment of all right, title, claim, or possession of the animal with the intention of not pertaining its ownership.

  • Section 8 o It shall be the duty of every person to protect the natural habitat of the wildlife. The destruction of said habitat shall be considered as a form of cruelty to animals and its preservation is a way of protecting the animals.
  • Section 9 o Any person who subjects any animal to cruelty, maltreatment or neglect shall, upon conviction by final judgement, be punished by imprisonment and/or fine, as indicated in the following graduated scale: ▪ Imprisonment of one (1) year and six (6) months and one (1) day to two (2) years and/or fine not exceeding one hundred thousand pesos (PHP 100, 000) if the animal subjected to cruelty, maltreatment, or neglect dies. ▪ Imprisonment of one (1) year and one (1) day to one (1) year and six (6) months and/or a fine not exceeding fifty thousand pesos (PHP 50, 000) if the animal subjected to cruelty, maltreatment or neglect survives but is severely injured with loss of its natural faculty to survive on its own and needing human intervention to sustain its life. ▪ Imprisonment of six (6) months to one (1) year and/or fine not exceeding thirty thousand pesos (PHP 30,000) for subjecting any animal to cruelty, maltreatment or neglect but without causing its death or incapacitating it to survive on its own.
  • Section 10 o The Secretary of the Department of Agriculture shall deputize animal welfare enforcement officers from non- government organizations and other volunteers who have undergone the necessary training for this purpose. The Philippine National Police, the National Bureau of Investigation and other law enforcement agencies shall designate animal welfare enforcement officers. As such, animal welfare enforcement officers shall have the authority to seize and rescue illegal traded and maltreated animals and to arrest violators of this Act subject to the guidelines of existing laws and rules and regulations on arrest and detention. - Section 11 o If for any reason, any provision of this Act is declared to be unconstitutional or invalid, the other sections or provisions hereof which are not affected shall continue to be in full force and effect. o All laws, decrees, orders, rules and regulations and other issuances or parts thereof which are inconsistent with the provisions of this Act are hereby deed repealed, amended or mortified accordingly. - Animal Science Specializations o Animal Breeding and Genetics – Bottom line objective is to select the best animals. o Nutrition – The most important environment factor for animal to express their best genetic potential is FEED. o Analogue Nutritionist – Its job is to give the best form of feed. o Physiology – Study of the mechanisms of life. o Animal Health – Study of how disease, parasites and environmental factor affect productivity and animal welfare. o Meat Science ▪ Meat, the edible flesh of animal this is used for food. ▪ Hence, meat science deals with handling, distribution and marketing of finished meat products. o Diary Product Science o Biotechnology – Rapidly growing because of newly- developed technologies (like recombinant DNA technology). - Ultimate Goal of Institutions o Produce individuals who can identify opportunities. o Capable to provide innovative solutions. - Domestication of Livestock o Began because of the need to survive o Initially, subsistence consisted of hunting and gathering o Control of food production gave an advantage to framers over hunter-gatherers o Selection has been fueled by domestication resulting to loss of native species in favor of defined breeds - When did domestication began o Approximately 12, 000 years ago, at the end of the Ice Age. o It was believed that concurrent with the end of the Ice Age, was the disappearance of mammoths, giant ground sloth and horses, which was then, the main food source. o This disappearance forced our ancestors to turn to farming. o The end of the Ice Age also brought Global Warming, which made it favorable for farming.

▪ Warmer temperatures ▪ Longer seasons for planting ▪ Increased rainfall

  • Domestication o Defined as a process of adapting animals to both humans and captive conditions. o Three (3) Pathways of Domestication ▪ Commensal Pathway ▪ Prey Pathway ▪ Directed Pathway o For Commensal and Prey Pathway, these animals are considered more docile and are easier to habituate, whereas those under direct pathway require skill to control.
  • Commensal Pathway o Occurs when animals move into human occupied territories where they feed on the waste created by humans. o Example animals are dog, cat and chickens.
  • Prey Pathway o Occurs when humans start managing animals which they initially considered as prey that they hunted, eventually herding them to control the supply of meat and hide. o Examples animals are sheep, goat and cattle.
  • Direct Pathway o Occurs when humans capture wild animals to control their production. This process is different from the Prey Pathway in that it skips management. o Sample animals include horse, donkeys and camels. o Not practiced anymore except for horses.
  • Question o Can the reverse of domestication happen (do domestic animals return to the wild)?
  • Domestication TimeLine o Dogs ▪ Domesticated 14, 000 years ago. ▪ Site of domestication is Asia. ▪ Ancestor is believed to be the Pleistocene Wolf (Canis Lupus), sometimes referred to as the Late Pleistocene Wolf or Megafaunal Wolf. o Cattle ▪ Domesticated 10, 500 years ago. ▪ Aurochs (Bos Primigenius) are its ancestors and can be found in East Asia, Europe and North Africa. ▪ Two (2) Major Types are: - Zebu (Prominent Hump), originated from Indus Valley. - Taurine (No Hump), from Anatolia. o Pigs ▪ Domesticated 9, 000 years ago. ▪ From the Eurasian Wild Boar. ▪ Sus Scrofa is believed to be from this ancestor. o Sheep ▪ Domesticated 8, 500 years ago. ▪ From the Mouflon (Ovis Orientalis). ▪ North West Iran and Anatolia were believed to be the center of domestication. o Goat ▪ Domesticated 10, 000 years ago. ▪ Believed to be domesticated first in the Fertile Crescent (Southern Iraq, Syria, Lebanon, Jordan, Palestine, Israel, Egypt, and parts of the Turkey and Iran). ▪ Wild ancestor was believed to be Bezoar, Capra Aegagrus. o Chicken ▪ Domesticated 8, 000 years ago. ▪ From South East Asia to China and then to India. ▪ Originated from the Red Jungle Fowl of Southeast Asia (Gallus Gallus). o Horse ▪ Domesticated 5,500 years ago from Ukraine. ▪ From an extinct ancestor, Equus Ferus located in Central Asia. o Ducks ▪ Domesticated 4, 000 years ago. ▪ Farmed in Europe and Asia. ▪ Wild Mallard (Anas Platyrhynchos) is believed to be the ancestor of all domestic ducks.
  • Types of Livestock o Cattle ▪ Dairy ▪ Beef

  • Breeder o Swine ▪ Full Production ▪ Fattener

o Most of the imported milk utilized for consumption further processing are sourced from New Zealand (46%), USA (29%), Australia (8%), and France (3%). o 85% of these imports are in the form of powdered milk (National Diary Authority, 2013).

  • Philippines Horse Industry o First used for food o In early times, for war o For sports o For draft purposes
  • Chicken o Egg or Layer production o Meat of Broiler production o Breeder Enterprise ▪ Pullet Production
  • Philippines Chicken Industry o Backyard Farm – Refers to any farm or household whether farming or non-farming raising at least one bird of animals and does not qualify as a commercial farm. o Commercial Farm – Refers to any broiler or layer farm which satisfied at least one of the following condition: ▪ Trending 500 layers or 1, 000 broilers. ▪ Tending 100 layers and 100 broilers if raised in combination. o Volume of Chicken Production and Annual growth Rate, Philippines: January – December 2018- 2020 ▪ Volume of Production (in million mt. live weight) - 1.84 (2018) - 1.93 (2019) - 1.81 (2020) ▪ Growth Rate (in percent) - 1.2 (2018) - 4.9 (2019) - - 6.1 (2020) o Distribution and Annual Growth Rate of Chicken Inventory by Type, Philippines: as of 01 July 2019- 2021 ▪ Distribution (in percent) 2019, 2020, 2021 - 43.0, 45.8, 45.2 (Native/Improved) - 36.0, 32.9, 31.1 (Broiler) - 21.0, 21.3, 23.7 (Layer) ▪ Growth Rate (in percent) 2021 - - 1.3 (Total) - - 2.7 (Native/Improved) - - 6.7 (Broiler) - 10.0 (Layer) o Top 10 Chicken-Producing Provinces Philippines: January- December 2020 (in thousand mt. live weight) ▪ Bulacan (185.09) ▪ Pampanga (164.48) ▪ Nueva Ecija (112.08) ▪ Tarlac (102.68) ▪ Batangas (102.48) ▪ Misamis Oriental (80.27) ▪ Quezon (73.37) ▪ Cebu (67.45) ▪ Rizal (66.74) ▪ Bukidnon (64.13) o Top 10 Chicken Egg-Producing provinces Philippines: January-December 2020 ▪ Batangas (151.88) ▪ Pampanga (69.72) ▪ Cebu (45.99) ▪ Bukidnon (34.16) ▪ Bulacan (26.36) ▪ South Cotabato (22.95) ▪ Davao City (19.75) ▪ Rizal (18.25) ▪ Tarlac (15. ▪ Negros Occidental (14.41) o Current Problems ▪ Important of leg quarters at dumped prices.
  • Do you believe that importation of chicken meat especially leg quarters have an effect on our local production? YES! ▪ Unreasonably low-priced important leg quarters are causing significant price distortion of broiler meat.
  • Example if you are buying from a local grocery store and they are advertising chicken meat for the price of PHP 120 up to PHP 130. But then you go to the market to buy locally produced chicken you will see that the prices are around PHP 150 for that.
  • You as a consumer, where would you buy your supply from? Naturally, you will buy from the cheaper alternative which is from your local grocery which imports chicken meat.
  • Some of the market sellers, they bought from groceries and then they sold the grocery store chicken meat as local stock. So they were buying from groceries around PHP 120 to PHP 130, and they were selling it at PHP 150.
  • But that doesn’t solve the problem of producing locally produced broilers because our country is continuously being dumped with a lower priced supply. ▪ A wide disparity between farm gate and retail prices of broiler that causes problems particularly to local individual broiler producers.
  • Example is if you buy from the farm at PHP 90 and then you will buy it from the grocery a PHP
  • What cause this very great disparity in the price? They would say gasoline or transport, but we will never know because as long as we don’t have an effective regulated body then they will be the ones who would control the prices. ▪ Apparent reduction of chicken meat is the cause of Highly Pathogenic Avian Influenza (HPAI) and Ebola Reston Virus, diseases also gives contribution to problems. ▪ End Result: Exceedingly high prices of broiler meat and a build-up in inventory.
