Our performance is always on trial

International research institutes, test farms and customers regularly test our products in feeding trials. The findings document the nutritional and functional advantages of our products and their long-term effect on animal performance overall.

Most importantly, the trials keep us on our toes – so we continue to deliver value-adding solutions to farmers around the world.

Results from 20 years of feeding trials with HP 300

A meta-analysis of 20 external feeding trials across 10 countries has confirmed what our customers have long experienced: that weaning feed containing HP 300 is more efficient than feed supplemented with other soy or animal-based proteins.

Feed intake, weight gain and feed conversion ratio are significantly improved – even after supplementation with HP 300 has come to an end.

Performance related to dosage

The feeding trials measured three primary performance parameters: average daily feed intake (ADFI), average daily gain (ADG) and feed conversion ratio (FCR).

The figures below show how each parameter improves when feed is supplemented with increasing doses of HP 300, ranging from 3.5% to 20%. 


To test any carry-over effect of feeding HP 300, weaning pigs were fed a common diet for a period after HP 300 supplementation. 

For every percent HP 300 received over the supplementation period, piglets gained an extra 0.1kg/0.2 lb live body weight compared to the control during the post-supplementation period. This shows that HP 300 has a positive carry-over effect on performance. With an inclusion of 20% HP 300, up to 2kg/4 lb extra weight gain was obtained in the nursery in total.


Performance example with 10% HP 300


Up to 1kg/2 lb extra weight gain in the nursery with HP 300

For every percent HP 300 received over the supplementation period, piglets gained an extra 0.1kg live body weight compared to the control during the post-supplementation period. At a dosage of 10% HP 300, up to 1kg extra weight gain was obtained in the nursery in total.


Facts on the feeding trials
• 20 feeding trials
• Across 10 countries
• All performed by external partners

The feeding trials compared HP 300 with:
• Soya protein sources: soya bean meal,
soya concentrate, full-fat soya, extruded soya
• Animal protein sources: skimmed milk powder,
whey, blood plasma, fishmeal.

Effect on gut health - study with HP 300

Study adds weight to healthy feed claims. Piglets have a healthier gut and gain more in weight when they are weaned on feed supplemented with HP 300 from HAMLET PROTEIN.

A study, conducted at CCL Research, the Netherlands, has compared the effect of our nutritious soy protein with that of standard soy bean meal on piglet growth and well-being.

Protein strengthens piglet growth
Pig farmers who choose piglet feed containing HP 300 can expect a smoother weaning phase with reduced susceptibility to E. coli bacteria, improved feed intake and increased body weight gain, according to this study. That means healthier animals and higher profits on the bottom line.

Conducted by CCL Research in The Netherlands, the study compared the effect on piglets fed a wheat-barley-corn diet supplemented with HP 300 or conventional soy bean meal. On day six and seven of the 14-day study, the piglets were challenged with E. coli K88 – a common bacteria in pigs and a frequent cause of diarrhea and piglet mortality.

Significant weight gain
Overall, the average weight gain of the piglets fed HP 300 was 28% higher than that of the group on the diet supplemented with soy bean meal, while feed intake increased just 14%. A substantial improvement in feed utilization was found.

“At this improved growth rate, piglets can be expected to reach a target weight of 30kg/66 lb in 72 days – around five days faster than the average for conventional feed,” says Lars Sangill Andersen, Nutritionist at HAMLET PROTEIN. 


In addition, the improved feed efficiency and lower age on reaching 30kg/66 lb gives a feed saving of around 3.5kg/7.72 lb feed per piglet.

High E. coli resistance
Faecal samples taken at regular intervals during the study period showed consistently lower faecal shedding of E. coli in the piglets on the HP 300-supplemented diet.

Lars Sangill Andersen puts the finding down to the composition of HP 300, which contains none of the natural soy sugars that promote E. coli growth in the gut.

“The low faecal shedding of E. coli is the direct explanation for the increased weight gain,” he comments.

“This shows the piglets were able to recover from stress more quickly – a significant benefit that saves labour, time and costs for the farmer.”

As good as animal protein at less cost - trial with HP 800 Booster

Blood plasma and fishmeal are widely regarded as the best protein sources for weaned piglets. Leuven University in Belgium tested this belief in a feeding trial that compared HP 800 Booster with blood plasma.

The results show that both protein sources give a similar good performance – and up to 15% savings in feed costs with HP 800 Booster.

Starting at the age of 18 days, 160 weaned piglets received one of the following three diets for 22 days:

• Control – containing 5% blood plasma, 8.6% HP 300
• HP 800 Booster 1 – containing 2.5% blood plasma, 12.2% HP 800 Booster
• HP 800 Booster 2 – containing 1% blood plasma, 17.1% HP 800 Booster

They were then fed the same diet for 23 days. 




Although feed intake was slightly lower with the HP 800 Booster diets than with the positive control containing 5% blood plasma, little difference was recorded in average daily weight gain – evidence that HP 800 Booster has an improved feed conversion ratio. Weight variance was reduced from 19% with the control to 13.1% and 15.8% with HP 800 Booster 1 and HP 800 Booster 2 respectively.

More weight gain after 37 days - trial with HP 800 Booster

A three-phase study by the University of Arkansas Animal Science Research Farm has found that HP 800 Booster increases piglet feed intake and has a long-lasting effect on average daily weight gain.

At the end of the 37-day study of 238 weaned piglets, piglets on the HP 800 Booster diet weighed 0.9kg/2 lb more than the piglets fed a diet based on animal proteins. Feed costs were also significantly reduced.

In the three-phase study, the university team demonstrated that feed intake increased with increasing doses of HP 800 Booster. Diets were formulated with 20% HP 300 from HAMLET PROTEIN and then to compare that with diets containing increasing amounts of HP 800 Booster. Piglets fed HP 800 Booster outperformed those fed both the positive and negative control diet.

During the first and second phase, the majority of the soya bean meal in the negative control diet was replaced with 20% and 15% of HP 800 Booster and/or HP 300, respectively. All piglets were fed a common diet in phase three.

The results show that HP 800 Booster improved feed intake by 7% during the 37-day study compared to the negative control. At the same time, piglets fed HP 800 Booster weighed 0.9kg/2 lb more than those fed the moderately complex positive control diet. Diets containing HP 300 also gave a better performance than the controls. Overall, the study revealed opportunities for feed cost savings of 16-17%.
