Saving Urban Poultry Farms from Closure

 

 

The Conflict of Poultry Production and Environmental Protection has been solved. Poultry raisers whose

poultry houses are located in urban areas are faced with the prospect of closure due to implementation of environmental laws by the Department of Environment and Natural Resources (DENR). Naturally, poultry owners would like to continue their operations to recover their investments and make a modest earning out of poultry raising Until recently, poultry raising in urban areas and complying with

environmental laws at the same time have been a problem for poultry owners. These problems have been solved. The solution is the application of a technology that was developed by a Filipino scientist inventor. This technology is simple, easy to learn and relatively cheap. The concept is the application of a microbial digester on the chicken manure. This digester ferments the manure. During fermentation, the digester:

 

(1) breaks down the cementing agents in the manure,

(2) prevents the emission of foul odor,

(3) destroys harmful microbes,

(4) conserves nutrients for plants,

(5) keeps the manure dry,

(6) controls the proliferation of flies. Read more…

Seaweed Processing

 

Carageenan is the name  given to the family of food grade materials obtained from red seaweeds. Carageenans are sulfate polysaccharides and are chemically similar. They differ in number and position of ester sulfate groups.

The carageenan family has three broad types product:

Kappa — strong gelling

Iota- weak geling

Lambda- non-gelling

Although there are other types, only kappa, iota and lambda are of commercial significance. They possess the properties applicable in food, pharmaceuticals, etc. However each has different processing and extraction methods from each other.

A. Kappa-Carrageenan

Although there are other types, only kappa, iota and lambda are of commercial significance. They possess the properties applicable in food, pharmaceuticals, etc. However each has different processing and extraction methods from each other.

A. Kappa-Carrageenan

This family contains about 35%, 3,6 —A6 and 25% sulfate, and being more hydrophobic, the free-thaw and gel-fresh processes used in Gracilaria agar production are quite applicable to Kappa-carageenan extracted from Eucheuma contonii (=Kappaphycus alvarezil)

B. Iota — Carageenan

This family of carageenophytes contains 30%, 3, 6— A6 and 32% sulfate and thus, more hydrochielec than kappa-carageenan. Iota carageenan has gelling properties in the presence of calcium ions. It is also difficult to be produced by the freeze- thaw or gel processes, so it is produced with alcoholic precipitation. Read more…

Pampanga’s Tilapia King

 

In the early ‘8os, Rustico Limpin was the

youngest among the group of fishpond operators in Mexico, Pampanga. His peers called him “Tiks” but since he was fond of taking orders and serving coffee during meetings, older colleagues started calling him Boy, nickname which he has learned to love because of its endearing reference to youth and innocence.

At that time, Mang Boy was already into aquaculture, raising sugpo and learning the intricacies of fish breeding. “Our fishponds were located in the downstream side of Mexico, Pampanga overlooking Manila Bay,” Mang Boy fondly recalls. However, the historic eruption of Mt. Pinatubo in 1991 destroyed the ecology of the area including hectares of fishponds which eventually overflowed with lahar. Left with no choice but to transfer their operations in the highlands, Mang Boy thought of raising tilapia, a cultured freshwater fish that originally came from Africa and introduced to the Philippines in the early ‘50s. This serendipitous moment paved the way for better opportunities not just for Mang Boy, but to hundreds of fishpond operators who also shifted to tilapia raising. Today, Mang Boy and his legions of fisher folks in Central Luzon comprise roughly 45% of tilapia growers all over the country. Read more…
