Madre de Agua as Chicken Feed
TL;DR: Madre de agua (Trichanthera gigantea) is a fast-growing fodder tree grown from cuttings and cut repeatedly for green forage. Chickens will eat the chopped fresh leaf, and it can be dried into a leaf meal. It is a supplement, not a feed — bulky and fibrous relative to its protein, so a bird cannot eat enough of it to live on. Most of the Philippine work on it concerns pigs and ruminants, which is worth knowing before you plan a flock around it.
One of the most commonly grown fodder plants in the Philippine countryside, and one of the most commonly overestimated.
What It Actually Is
Trichanthera gigantea, a shrub or small tree grown across the Philippines as cut-and-carry forage. The useful properties, and the reason smallholders plant it:
- It grows fast and regrows after cutting, so one planting supplies leaf continuously.
- It propagates from stem cuttings, which means no seed cost and easy sharing between neighbours.
- It tolerates moisture and partial shade, and is often planted along waterways and field margins — which is where the name comes from.
- It is cut back repeatedly rather than allowed to reach full size.
For a keeper, that combination is the whole appeal: a green feed input you grow rather than buy, on land that was not doing anything else.
Where Chickens Fit
Honestly: at the edge.
Chickens will eat chopped fresh madre de agua leaf offered in the run, and the leaves can be dried and ground into a leaf meal that goes into a mixed ration. Both work.
But the plant’s characteristics suit a different animal. Green forage of this type is bulky and high in fibre relative to its protein, and a chicken has a small digestive capacity and limited ability to extract value from fibre — see chicken anatomy on the gizzard and the short gut. A pig or a goat can eat enough of it to matter. A hen fills up long before she has taken in much.
That is why nearly all the Philippine extension material on this plant concerns pigs and ruminants. It is not that chickens cannot eat it. It is that the plant is doing less for them.
What it is genuinely good for in a flock:
- Green material for birds without range. Confined birds get no greens at all, and this supplies them cheaply.
- Occupation. A hung bundle of leaves gives a penned flock something to work at, which matters for feather pecking.
- Cutting the greens portion of the feed bill at the margin, not the ration itself.
Fresh Leaf or Leaf Meal
| Fresh, chopped | Dried leaf meal | |
|---|---|---|
| Effort | Cut and chop daily | Dry, grind, store |
| Storage | None — feed the same day | Keeps, if kept dry |
| Use | Offered in the run | Mixed into a ration |
| Risk | Wilts and spoils fast | Mould if stored damp |
The drying step is where problems start in a humid climate. Leaf meal that has taken up moisture in storage will mould, and mouldy feed is discarded, never fed — see what not to feed chickens and, for what mould does to a bird’s airway, aspergillosis.
If you dry leaf, dry it properly and store it sealed and off the floor. The same discipline that applies to darak applies here, and for the same reason.
What This Guide Will Not Give You
An inclusion rate. Published percentages come from controlled trials with a defined ration, a defined bird type and a defined stage of production. Lifting a number out of a pig trial, or out of a broiler trial run on a ration nothing like yours, and applying it to a backyard flock is how a supplement becomes a problem.
The sensible version for a backyard keeper: a modest amount of chopped fresh leaf alongside a complete feed, watch intake and droppings, and stop if either changes. If you are formulating a mixed ration seriously, that is a conversation with an agrivet or a livestock extension officer at your municipal agriculture office, not something to take from an article.
Growing It
- Plant stem cuttings rather than seed.
- Moist soil, partial shade. It does well where other forage struggles.
- Cut repeatedly once established, rather than letting it grow tall.
- Plant more than you think you need. Cut-and-carry forage always yields less usable leaf than the standing plant suggests.
It fits well along a fence line or a wet corner, and it pairs naturally with a free-range or pastured system where birds are already getting some of their intake from the ground.
In Context
Madre de agua is one input among several a Philippine keeper can grow or buy locally. The realistic picture:
| Input | Role |
|---|---|
| Azolla | Grown on water, higher protein than tree forage |
| Ipil-ipil leaf meal | Higher protein, but carries a real anti-nutritional limit |
| Black soldier fly larvae | The serious protein option among home-grown inputs |
| Madre de agua | Green bulk and occupation |
| Darak | Energy, cheap, spoils fast |

The Honest Limits Here
That Trichanthera gigantea is a fast-growing, cutting-propagated fodder plant widely used for livestock in the Philippines is well established, and its use as green forage for poultry is a recognised smallholder practice. This guide gives no nutrient composition figures and no inclusion rate, because published values vary with soil, age at cutting and drying method, and because trial inclusion rates are specific to the ration and bird they were tested on. It will not replace a balanced feed. If you are building a mixed ration rather than supplementing one, ask an agrivet or your municipal agriculture office.

Frequently Asked Questions
What is madre de agua?
Trichanthera gigantea, a fast-growing fodder shrub or small tree widely grown in the Philippines as green forage for livestock. It is propagated from stem cuttings and cut repeatedly for its leaves.
Can chickens eat madre de agua?
Yes, as green forage. Chickens will pick at chopped fresh leaves, and the leaves can also be dried and ground into a leaf meal that goes into a mixed ration.
Can it replace commercial feed?
No. It is bulky and high in fibre relative to its protein, and a chicken cannot eat enough of it to meet its requirements. Treat it as a supplement to a balanced ration, not a substitute for one.
What is madre de agua called in Tagalog?
It is generally known by the Spanish-derived name madre de agua across the country. Regional names vary, and the scientific name Trichanthera gigantea is the reliable identifier when buying planting material.
How is it grown?
From stem cuttings, and it establishes readily in moist soil with partial shade. It is cut back repeatedly rather than grown to full size, which is what makes it useful as a continuous forage supply.
Is madre de agua better for pigs than for chickens?
Most Philippine research and extension material on it concerns pigs and ruminants, which handle bulky high-fibre forage far better than chickens do. That is worth knowing before planning a poultry system around it.
How much should I feed?
This guide gives no inclusion rate. Published rates come from controlled trials with specific rations and bird types, and the sensible approach for a backyard flock is a modest amount of chopped fresh leaf alongside a complete feed.
