Thai Nguyen province in northern Vietnam has taken a step toward trademarking \"green tea pork\" (thit lon tra xanh), raising pigs on feed mixed with the local main product, tea. The August 10, 2026 edition of the Agriculture and Environment newspaper reports the province's move to lift its livestock sector through high-tech and circular models. This attempt to turn tea leaves into a functional feed ingredient to differentiate meat offers one concrete answer to the question of how to break through the weakness of Vietnamese livestock\u2014strong in raw-material supply, weak in brand and processing. For Japanese meat buyers and the processing\/OEM side too, there is much to read in it as a design that turns a by-product into a high-value-added product.<\/p>\n

1\u20135% green-tea powder in feed; a formulation Thai Nguyen University of Agriculture and Forestry verified with 72 pigs<\/h2>\n

At the core is a feeding trial advanced by Thai Nguyen University of Agriculture and Forestry (Truong Dai hoc Nong Lam Thai Nguyen). The research team mixed green-tea-leaf powder (bot la che xanh) into the pigs' daily feed and compared meat quality and growth across four addition levels of 0%, 1%, 3% and 5%. Two lines\u2014native black pig and commercial meat pig\u2014were tested, measured at a scale of 9 head per group, 72 head in total. The project lead is Dr. Nguyen Tien Dat (Nguyen Tien Dat).<\/p>\n

Green tea contains antioxidant and antibacterial components such as polyphenols, catechins and tannins. In the trial, it was reported that in the green-tea groups the pigs' immunity rose and digestive-system troubles decreased. Changes appeared in the meat itself too: the proportion of fat fell, and the meat's redness and water retention increased. In other words, the thread that \"raising pigs on tea makes them healthier and gives leaner, moisture-retaining meat\" was backed by measurements taking the difference in addition levels. That odor on the farm was suppressed and reliance on antibiotics could be reduced is also cited as a secondary benefit of this feed design.<\/p>\n

About 20% higher in live weight; the brand \"Thit lon tra xanh\" trademarked and spreading farms<\/h2>\n

The difference in taste and functionality shows up in price too. In the extension model that Thai Nguyen province's Agricultural Extension and Environment Center (Trung tam Khuyen nong va Moi truong tinh Thai Nguyen) ran in the Tan Cuong area (xa Tan Cuong) in 2026, the live-weight price of green-tea-raised pigs was reported to be roughly 20% higher than ordinary pigs. At the research stage, bullish figures were also reported that some cuts sold at two to three times the usual, but the on-the-ground price confirmed in actual trading is at the \"20% higher\" level.<\/p>\n

This model was run around the Toan Lieu Cooperative (HTX Toan Lieu), raising 50 head at three households and transferring the technique to 20 households inside and outside the cooperative. Across the province, on a reporting basis, 19 facilities have registered for green-tea raising, and the number of head raised is said to exceed 1,640. In December 2025, the provincial Department of Science and Technology and the university of agriculture and forestry announced the Intellectual Property Office's trademark for \"Thit lon tra xanh \u2013 Tinh hoa Thai Nguyen (green tea pork, the essence of Thai Nguyen).\" Not stopping at an ingenuity of raising method but enclosing it as a registered trademark tied to the growing region's name\u2014here the intent to break out of a raw-material contest can be seen.<\/p>\n

Thai Nguyen livestock with 1,600-plus farms and 103 large-scale operations, and the wall of African swine fever<\/h2>\n

Green tea pork is also one move within a flow modernizing the province's livestock sector as a whole. According to the province's livestock, veterinary and fisheries sub-department, Thai Nguyen province has more than 1,600 livestock farms and over 100,000 small-scale raising households, of which only 103 are large-scale farms. At major farms, they have come as far as managing herds with production-management software, monitoring barn environments with sensors, and raising in closed, automated barns. On the other hand, sub-department head Dinh Thi Hong Chiem acknowledges that the share of high-tech raising is still low and that small-scale dispersion being the mainstream is a wall to technology investment.<\/p>\n

That investment is large and takes time to recoup, that access to credit and funds is difficult, and that the risk of outbreaks of African swine fever and avian influenza continues are slowing progress. The province sets out a policy of reducing small-scale raising and growing large-scale farms going forward, and\u2014after putting in place disease-safe zones and biosafety facilities\u2014steering toward green-circular, digitized livestock. It is trying to place branded items such as green tea pork as the outlet of this structural shift.<\/p>\n

From a tea region's by-product to functional meat\u2014what Japanese procurement and processing should read<\/h2>\n

Thai Nguyen is the pinnacle growing region of Vietnamese tea<\/a>, with a tea-garden area of about 22,000 ha. It is precisely because tea leaves are abundant, led by the famous Tan Cuong tea, that the idea of diverting them to a feed ingredient holds up. Reorganizing a region's surplus primary raw material into another high-value-added product rather than exporting it as is\u2014this move is a grounded answer to the question of how to fill in the weakness in processing and standardization, a structural challenge of Vietnamese agriculture<\/a>.<\/p>\n

Seen from the standpoint of Japanese meat procurement and OEM, three points of interest stand out. First, the addition level of 0\u20135% is managed by numbers, and the meat quality can be discussed by indicators such as fat ratio and water retention. A stance of underpinning the brand with measurement, not just a story, suits import-time quality explanation and traceability. Second, a realistic premium of 20% in live weight. Trying to run it on a payable premium rather than an exaggerated multiple is solid in the sense of trade durability. Third, the build that turns small-scale dispersion to advantage\u2014transferring technology with cooperatives at the core while enclosing it with a trademark. Branding cases of Vietnamese agriculture<\/a> placed side by side, it becomes clear that they are trying to reproduce in livestock the same mold of \"from raw material to processing and story\" as coffee's roasting and own-brand development.<\/p>\n

Where a tea region's differentiated livestock stands now<\/h2>\n

Green tea pork is still at the stage of a 72-head trial and an extension model on the scale of a few dozen households. There is a gap between the research-stage figures stressing a multiple and the on-the-ground feel of 20% higher in live weight, and the stability of export-worthy supply volume and standards is a challenge from here. Even so, in that it is designed consistently\u2014reorganizing tea, a region-specific raw material, into feed, showing functional and leaner meat quality by measurement, and protecting it with a trademark bearing the region's name\u2014this initiative goes beyond mere buzz-making. Thai Nguyen's choice to raise pigs on tea is worth following for Japanese procurement staff too, as a microcosm of Vietnamese livestock trying to move from a raw-material country to a processing and brand country.<\/p>\n
