Natural Farming
Natural farming is one of the old methods of producing crops. In natural farming, crops are grown without the aid of chemical fertilizer, herbicide or pesticide. It is much better because the produce does not contain chemicals which can be absorbed by the crops with the use of chemical fertilizer, herbicide or pesticide. Natural farming does not till the land but uses earthworms, microorganisms and small animals.

Natural farming does not have any standards like organic farming. Though it does not have any body like structure to monitor natural farmers, it is better than commercial farming for it produces healthier crops for the consumers.

One of the most important aspects of Natural Farming is that the farmers make what they need. Fertilizers, soil improvers, pest controllers, disease cure are all made by the farmers themselves using only natural materials. Natural Farming can be a powerful tool for the third world farmers who cannot afford to buy expensive imported farming inputs.

Natural Feeds
Natural feeds are those which contain natural ingredients. The feeds produced are cheaper than commercial feeds. It is better for animals for it contains more nutritive value from natural ingredients. Unlike commercial feeds, it is safer for the animals for it does not contain antibiotics, chemicals and the like.

Mass Chief Feeds was inspired by natural feeds. The product is made up of grinded GAS with the combination of cassava. Livestock industry can become more profitable by using our product for it is specifically made for them to save on costs yet produce high yield.


*Records suggest that there are more than one species of Pomacea present in the Philippines. FAO and the Commonwealth Agricultural Bureau-International Institute of Biological Control (CAB-IIBC) identified the GAS as Pomacea insularis (Acosta and Pullin, 1991). Based on the morphological characteristics, GAS was identified as Pomacea canaliculata at the International Rice Research Institute (IRRI) (Saxena et al., 1987). According to Mochida (1987), P. canaliculata was introduced to Batangas from Taiwan in 1982. P. gigas from Florida were introduced to Makati Metro Manila in 1983. Another Pomacea species was directly introduced from Argentina to Cebu in 1984. Pila leopordivillensis, an African snail, was introduced from Taiwan. Pomacea cuprina is also found in the Philippines (Mochida, 1987). But Golden Apple Snails were determined by PhilRICE as what is popularly known as “golden kuhol” (Pomacea canaliculata Lamarck). To sum up, most of the published reports refer GAS in the Philippines to as P. canaliculata. Source:PhilRICE

Golden Apple Snail came from the phylum mollusca, within the family of Ampullariidae. It is a genus of Pomacea and included in the specie of canaliculata (Lamarck, 1819).

Physiological Structure and Anatomy
The eyes of the apple snail are located at the base of the tentacles, on top of the eyestalks. The structure of the eye does not provide detailed vision; they rather function as directional light sensors that give the snail an orientation towards light sources. Colour vision is absent as the retina does not contain colour specific photo sensors: an apple snail is colour-blind. The tentacles are very important sensory organs. Apple snails highly rely on the smell capacity and the sensitivity of their tentacles to navigate in their environment.

The osphradius is a chemosensory structure that is located in the mantle cavity, in front of the lung. The osphradius gives the snail the capability to smell chemical substances in the water.

The statocysts (2) are vesicles containing a statolith (little stone like structures composed of calcium carbonate). They function as balancing organs, used by the snail to detect its position with regard to the ground....
