Nutrient digestibility and requirements for energy and digestibility acids in growing Philippine native pigs (Sus scrofa domesticus)
2018
Villanueva, J.J.O.
The research aims to establish nutrient requirement standards for growing Philippine native pigs (Sus scrofa domesticus). In study 1, a total of 240 native pig raisers were personally interviewed as respondents. Results reveal that majority of respondents were male, in their productive age, married, finished elementary education and with 1-5 household members. Common problems encountered consist of inadequate capital, lack of technical knowledge, diseases, low market price and high cost of feeds. Parents and friends are sources of knowledge and information in native pig raising. Overall, majority of the respondents employed traditional practices in terms of feeds and feeding, housing, breeding, health and disease prevention, and marketing. In Study 2, a total of six Philippine native and nine hybrid pigs were used to compare the digestibility nutrients, energy and dietary fiber in conventional feed ingredients. Result showed that ATTD of GE, DE and ME of the diet were greater (P0.001) for native pigs compared with modern crossbred pigs. Native pigs had greater (P0.03) ATTD of CP, crude fiber, NDF, ADF, and ash and tended (P
