The Impact of Typhoon Odette on our Livestock

The morning after a whole night of typhoon Odette (Rai)


Typhoon Odette was very destructive. Our neighbors that kept poultry in cages suffered losses. Our ducks and chickens were unharmed because they were free ranging and found their own safe places. The couple chickens in a small coop under the house were okay. Even the newly hatched ducklings were fine beneath their mother’s wings. Majority of ducks and chickens stayed under the house, protected from wind, rain and falling and flying debris. One young chicken stayed in her comfortable roosting place, a beam over the entrance of the house, about 12 feet high above the ground. It was a safe place because the roof of the house protected her.

Pigs seasonally allowed to forage.


The biggest impact was on the pigs. When the typhoon landed, I had a boar, two gilts and one very pregnant sow due in 2 weeks. A portion of the boar pen roof and fence was damaged by a fallen coconut tree. The sow housing was surrounded by fallen branches and trunks of gmelina, mango, ficus and various other trees. The pen where the two gilts stayed together was about a foot deep with muddy water.

The morning just after the typhoon we had to get help clearing the paths. It wasn’t easy going under and over fallen debris to feed the pigs. The boar and gilts were hungry and eager to eat. However, the sow seemed the most distressed. She ate, drank and lay down exhausted.

When the sow farrowed two weeks later, she had so much troubles. She was distraught, feverish, and seemed determined to lay on all her piglets. She had 15 piglets and when it seemed like they were all going to die, we decided to collect what was left and raise them ourselves. The piglets were not even two days old when we took them away from the sow.

The sow recovered and the piglets that survived made it to weaning age and were promptly sold. All seemed well, but there were a few subtle changes that I felt were an effect of the terrible distress brought by the typhoon.

For sure, all the pigs are more cautious and nervous and irritable than usual. The least affected are the two gilts. This is probably because they are housed together and had each other for social support. The boar, nearing 7 years of age, seemed unaffected. Beneath the debris of roofing sheets and broken lumber, he was more concerned with getting fed. However, he is now more easily agitated by the presence of people particularly if they are making noises around his pen.

The sow in her spacious pen. Unfortunately, she seem to be suffering from an anorexia-like wasting syndrome as a result of environmental stressors.

The most tragic impact was upon the sow, now nearing 4 years of age. The failure to care for her piglets was the first most obvious tragedy. Then over a month ago, her distress culminated in inappetence. I was puzzled and considered all sorts of viral or bacterial infections. But the symptoms were not there. The behavior linked to inappetence was so strange: more motivated rooting, crossing of back legs while walking, yawning, vocalizations in response to the boar. There were moments when she seemed to be getting better and started eating, but this would stop and she would return again to being a terribly picky eater. What she ate a little of today, she won’t eat tomorrow. She drank but not as plentiful as her usual self, and she would turn over her drinking bowl as if looking for something else beneath it.

The sow escaped from her pen once and visited the boar. I have put them together now and she is free to root in a large space. I wanted her to be as comfortable as possible, free to roam and choose the food she wishes to eat, and to have company. The symptoms, I think, are more psychological (and at the same time hormonal) than anything else.

At this point, I did several minutes of Googling and found what may be the answer to this mystery: Anorexia-like Wasting Syndromes in Pigs

I read that influencing the serotonin in the brain may be a solution but I don’t have the means to do this on this island. Typically, this sow would’ve been culled a year or two earlier. But I don’t cull hard, unfortunately, because the facilities available for doing this to large animals is too cruel for my standards.

These are huge pigs more intended for intensive rather than pasture production. Nonetheless, these pigs enjoy rooting outside. They return to their pen when it gets too hot or when it rains too much.

This year, I have been working hard on a lot of changes that I didn’t get the chance to do over the past 12 years. Now my pigs have more space and freedom to root and forage. I continue to learn by observing the areas where they root and see how seasonal foraging would allow the growth of plants. With a very small herd, it is sooner than later possible to move away from large domesticated pigs that I currently have – a mix of typical industry breeds such as duroc, largewhite, landrace and pietrain – and transition to the much smaller and robust Philippine native pig. By the time I am ready to transition, the right breed for this island environment will hopefully be available. The fenced areas for the pigs may also be used for goats and perhaps other meat birds such as Rhode Island Reds which are quick finishers and aren’t as wild and rowdy as the native chickens.

Lately, I’ve sold enough of the ducks and chickens so that the crops would have a better chance of growing. I’ll be transitioning to growing more crops that we can eat, more native plants and trees for the wildlife, and hopefully diversifying into simple aquaculture. I already have tilapia but would like to add “hito” or mudfish) and freshwater lobsters (crayfish). Aquaculture is quite important to me because I am experiencing the effect of pollution on marine resources on this island and I think that fish and seafood provide essential nutrients that other sources cannot.

Overall, my values and goals have not changed. I grow food for our consumption, not for commerce. If there’s anything to sell it’s because there’s surplus. When we take good care of nature she is very capable of providing abundantly.

La Niña and Outlook for Philippine Forage Crops

We are currently experiencing the extended effects of La Niña. La Niña is defined as the positive phase of the El Niño Southern Oscillation (ENSO) associated with cooler-than-average sea surface temperatures in the central and eastern tropical Pacific Ocean. La Niña is said to impact global climate, disrupting normal weather patterns and can lead to intense storms in some places and droughts in others.

In the Philippines, La Niña often means heavy rains and as a consequence, flooding. According to the “Climate Outlook (January-June 2018)” by the Climate Monitoring and Prediction Section of PAGASA-DOST, “Weak La Niña is present in the Tropical Pacific; may not last beyond March 2018, but varying impacts occur.”

Rainfall Forecast:

  • January 2018 – below normal rainfall over western Luzon while generally near to above normal over Eastern Luzon and most parts of Visayas and Mindanao;
  • February 2018 – generally near to above normal rainfall with some patches of below normal rainfall over Ilocos area; Visayas and Mindanao, generally above normal rainfall;
  • March 2018 – below normal rainfall over western Luzon while generally near to above normal over Eastern Luzon and most parts of Visayas and Mindanao;
  • April 2018 – generally below normal over most parts of Luzon (except western Luzon); the rest of the country will likely experience near normal rainfall conditions.
  • May 2018 – generally near to above normal rainfall;
  • June 2018 – near normal rainfall over major parts of the country, while below normal rainfall conditions will be likely over northern Luzon.
  • Generally, near average to slightly warmer than average surface temperature is expected over the coming months over most parts; slightly cooler than average over the mountainous areas in Luzon in January-March 2018; cold surges may occur in December to February 2018.
  • 2 to 5 tropical cyclones may develop or enter the Philippine Area of Responsibility (PAR) from January – June 2018.

Outlook for the West Garden:

Construction work took place around the western side of the garden in October-November 2017. We started mulching and building rain gardens, paths and plant beds in the effort to get as many crops growing as quickly as possible and to control flooding from storm water run-off in the area.

Forage is one of the most important crops we planted. We don’t have enough forage for the animals and would like 2018 to be the year when we would grow and double our production. Some of our current forage crops are: desmodium rensonii, indigofera zollingeriana, trichantera gigantea (madre de agua), and mini water cabbage.

Indigofera for forage.
Indigofera has 27─31% crude protein, which is relatively higher than any of the locally available leguminous forages. Leaves and twigs are harvested every 30 days to maintain their succulence. Indigofera is not to be confused with Creeping Indigo (indigofera spicata) which may be toxic to some livestock.

Desmodium cinereum (Rensonii) is a leguminous plant tagged as “alfalfa of the tropics” because of its high crude protein content at 20-23% of dry weight. Regular cutting stimulates multiple stems and increases yields of leaf. If seed production is required, defoliation must be timed to avoid destroying the developing seed crop. Not well suited for grazing or browsing.

Trichanthera gigantea is generally propagated from cuttings selected at the basal part of young stems. These cuttings can either be planted directly or put in plastic bags for transplanting later. Harvest begins 8 to 10 months after establishment and the first yields are about 15 t/ha of fresh matter. Trichanthera gigantea can be harvested for foliage every 3 months and yields 17 t/ha of fresh matter at a cutting height of about 1 m. Under hotter and drier conditions, cutting heights can be higher (1.3-1.5 m).

Growing but not thriving well are: ipil-ipil, madrecacao, mani-manian, malunggay and water hyacinth.

Failed to survive are: stylo.

We are looking for seeds/cuttings/seedlings of the following: napier grass, mulberry, mara mais, stylo, azolla.

Papaya planted in the west garden two months ago.

Forage and roughage for pigs and goats also come from the following: various fruit trees such as papaya, langka, banana, coconut, gmelina, mahogany, tiesa, tambis, balimbing; various green leafy vegetables such as amaranth, camote (leaves), kangkong, saluyot, alugbati, casava (leaves), talinum; and various grasses such as carabao grass, paragis, mimosa, busikad, etc.

Sow eating various common grass pulled out from the garden.

Ornamental plants that are trimmed also provide some forage but only in small quantities since some are considered mildly toxic: San Francisco plant (croton), various cultivars of canna, Fortune plant (dracaena), ornamental palms, ferns, wandering jew, lantana, duranta etc.

Piglet foraging in the garden.

La Niña does not deter us from developing the west garden. We have planted forage crops in and around the area. Normally, the rainy/wet season is also good vegetable planting season in the Philippines because this eliminates the need for artificial irrigation. However, tropical vegetable production experts note that the rainy season also means high humidity amidst high temperatures conducive to the proliferation of pests and disease. This is where disease and pest-resistant crops are valuable and topping the list of recommended plants are those with edible foliage and shoots.

Recommended Vegetables for the Rainy/Wet Season:

Rooted taro, kangkong (water spinach) and camote (sweet potato) are easier to grow in wet and flood prone areas. The red and green varieties of taro we planted in the newly dug up rain gardens are doing well.

Okra, eggplant, beans, chili, corn/maize, squash and some gourds are known to thrive in wet conditions. However, they need to be planted in raised beds so they are protected from flooding. When seedlings have established at about 1-2 weeks, mulching needs to be done all around the seedlings in order to protect them from the battering downpour of rain. We have lost many young sprouts to heavy pouring rain, unfortunately, so we are also planting seeds in the beds where mulch have already been applied. The surrounding mulch protect some of the seedlings. Planting under a tree or bush also helps, as long as the area does not get flooded.

Taro thrives well in the rain garden.

 

Toxic Plants and Weeds

Although many plants are toxic in various ways, we try not to allow those with high toxicity to colonise the garden, particularly the weeds. While animals avoid eating plants that are toxic, we also try to identify which plants may be toxic and avoid giving those to the animals. Toxic plants we currently have are Estrella, Sinkamas (seeds are toxic), Sagilala (San Francisco/Croton), Red Ginger, Lantana, Katakataka (linked to some cattle poisoning), Buddha Belly Plant (ginseng in Tagalog), Cat’s Whiskers (Balbas Pusa), Castor Oil Plant (Tangantangan), Bangkok Kalachuchi (leaves and flowers are toxic to goats and cattle), Plumeria.

Estrella (above) contains a toxic alkaloid, isotomine that can cause muscle paralysis and affect cardio-respiratory functions.

Protecting Plants from Chickens and Ducks

Chickens and ducks love foraging after a downpour. The earth is soft and is easy to dig up as chickens and ducks search for bugs, earthworms, seeds and seedlings. Even if the fowls are sufficiently fed, they still want to go around and forage, especially the chickens. Below are some of the methods we are implementing, hoping to duck and chicken-proof the garden. Admittedly, we are not always very successful but some plants do manage to grow this way.

Seeds are planted between coconut husks – another attempt at chicken-proof gardening.

Portable plastic netting frames are placed over seeds, seedling for protection.

Seeds are planted between stakes for chicken-proofing.

Other methods at chicken-proofing include fencing out raised garden beds and putting pots on wood stumps away from sight of chickens and ducks.

It has been two months since we started work in the west garden amidst the effects of La Niña. Work continues to minimise the effects of flooding and hopefully, get plants to grow and get established before what might be a long season of drought in the near future.
