Field results

Controlled trials on commercial farms, each comparing animals fed D68 with a control group under the same housing and management.

Weaned piglets

660 Duroc × Landrace × Yorkshire piglets weaned at 24 days and about 7 kg, split randomly into two groups.

Dose: 500 g D68 per ton of feed
Length: 28 days
Location: Commercial farm, Hebei, China

Body weight at day 28+1.38 kg

Control15.78 kg

With D6817.16 kg

P = 0.03

Average daily gain+15.9%

Control315 g

With D68365 g

P = 0.01

Feed conversion ratio (lower is better)−6.7%

Control1.78

With D681.66

P = 0.03

Laying hens, drinking water

30,000 hens aged 150 to 210 days in four houses: two control, two receiving D68 in water.

Dose: 0.1 g per hen per day
Length: 15 days

Laying rate at end of trial+2.65 pts

Control94.70%

With D6897.35%

Daily egg mass per 15,000 hens+28 kg/day

Control863 kg

With D68891 kg

Average egg weight+0.25 g

Control60.75 g

With D6861.00 g

Pullets, 1 to 10 weeks

105,000 day-old pullets at a breeding company farm, in three groups of 35,000: control, 250 g/t and 500 g/t D68.

Dose: 250 g per ton of feed
Length: 10 weeks

Body weight at 10 weeks+18.9 g

Control764.8 g

With D68783.7 g

Breed standard at 10 weeks: 750 g

Flock uniformity at 10 weeks+3 pts

Control88.5%

With D6891.5%

Laying hens with wet droppings

Commercial layer flocks with watery droppings, a common sign of gut damage that cuts laying rate by 3 to 5% and raises feed per egg.

Dose: 0.1 g per hen per day in water

Outcome with D68	Result
Incidence of watery droppings	down more than 80%
Laying rate	+3% on average
Feed-to-egg ratio	−0.1 to −0.2
Return on investment	1 : 4.68

In a separate Hebei trial, the share of hens with diarrhea fell from 68% to 41% over 13 days, and rose again to 60% three days after D68 was withdrawn.

Broilers

Six broiler houses under independent control, plus a side-by-side comparison of two flocks from day 25 to slaughter.

Outcome with D68	Result
Overall survival rate	+0.55 pts
Overall feed conversion ratio	−0.03
European Production Efficiency Factor	+11.4
FCR at slaughter, side-by-side flocks	1.415 vs 1.572 control

At 200,000 birds marketed at 3 kg, a 0.55-point survival gain means about 1,100 more birds to market.

Aquaculture

Shrimp ponds facing Vibrio, the largest single cause of losses in shrimp farming.

Outcome with D68	Result
Vibrio counts in water and shrimp	down by one order of magnitude
Survival rate	+5 to 10%
Average body weight and growth rate	significantly higher

All trials were run in China between 2024 and 2026 with commercial producers and research partners. Full reports, including statistical methods, are available on request.
