Abstract
In recent years, competing with China and Thailand, Vietnam wild pork meat processing and wild pig feeding have become hot food processing issues. Currently, EU livestock products exported to Vietnam are subject to 10-20% tax rate. However, under the EVFTA agreement, frozen pork will be tax-exempt after seven years, processed foods after seven years, and the tax rate for chicken will gradually decrease to 0% in 10 years. This study will use qualitative analysis, synthesis, and inductive methods, with statistic data, examines experiences from Asian countries such as Thailand and China and meanings to Vietnam case of feeding wild pigs. Among present results is relating to wild pork meat and frozen pork processing in the case study of wild pigs in Northern provinces of Vietnam such as the Thai Nguyen region. And also, it describes the process of processing pork meat with chili sauce and frozen pork meat. Our study will present a feeding mechanism for wild pigs under semi-wild breeding conditions in the Thai Nguyen ecological environment. Asia, including Vietnam, has a good environment for feeding wild pigs and establishing pig farming. Our study has indicated researches and publications are needed for supporting exporting wild pigs and pork.
Highlights
In Vietnam, the wild pig is found in most of the forest areas of the provinces, especially the northern mountainous areas and along with the Truong Son Mountain range
The feeding process of wild pigs is as follows (Olesen et al, 2018; Sevilla et al, 2020): The process of raising commercial wild boar at wild pig farm: After three months of age from the date of birth, Wild boars must be moved from the concentrated farming area to the wild farming area
Our study has indicated researches and publications are needed for supporting exporting wild pigs and pork
Summary
In Vietnam, the wild pig is found in most of the forest areas of the provinces, especially the northern mountainous areas and along with the Truong Son Mountain range. Research results often focus on the following content: Research results on reasonable protein and energy levels; Research results on the addition of protein and amino acid ratios from different feed sources for pig breeds as well different for commercial crossbred pigs (Jiang et al, 2011; Schiavon et al, 2018). This is the basis for balancing diets with reasonable protein and energy levels for wild boar and hybrid wild boar (Razmaitė & Švirmickas, 2012). Le Dinh Phung and Ha Thi Nguyet in 2011 studied wild behavior of Thai wild boar with birth weight 0.37 kg/head, weaning weight at 120 days reaching 13.83 kg/head, and the main ratio was banana stem, water spinach, water hyacinth, and 0.3 kg of rice bran is added/time for growing pigs (Pham et al, 2014). Thom & Huy (2021) studied the biological characteristics of wild boars in Thailand and Vietnam, but the nutritional requirements for this breed have not been studied
