Joubert de Lange and his team at ProTen’s Henderson Farm was the top performer in 2020, reaching an impressive European performance efficiency factor score of 475.17.
Exclusive Ross 450 Club membership is reserved for poultry producers who through teamwork, skillful stockmanship and dedi- cation score an EPEF of 450 or higher across the farm for one full grow- ing cycle.
“Congratulations on a job well done!”
“We look forward to seeing what our custom- ers accomplish in 2021,” Mr Leahy said.

Breed of choice
OPTIMISING the gut microbial community and morphometrical traits has become an in- creasingly prominent area of research due to recent evidence that suggests gut health and functionality affects the production performance of broilers.
A 42-day grow-out trial was conducted using 192 Ross 308 broilers to de- termine if super-dosing Natuzyme at 0g/t, 350g/t, 700g/t, and 1000g/t dose rates could improve the gut morphology, alter the cecal microbial profile, enhance bone mineralisa- tion and improve nutrient digestibility of a wheat– corn–soybean diet – six replicates per treatment, eight birds per pen.
Yet, 700g/t Natuzyme promoted microbes be- longing to the genus rom- boutsia and ruminococcus gauvreauii, while 1000g/t Natuzyme promoted barnesiellaspecies.
Creating a diverse mi- crobial population can in- crease the nutrient digest- ibility of feed, as the mi- crobes can break down a large portion of macromol- ecules and convert them into bioavailable substrates to be utilised by the host.
The nutrient digestibility demonstrated a significant improvement in all en- zyme doses compared to the control.
A diverse microbiome can be promoted by a vari- ety of additives, including feed enzymes.
The addition of enzymes tended to increase the vil- lus height in the duode- num, villus height, width and crypt depth in the jeju- num, and villus width and the number of goblet cells in the ileum.
This summary and ab- stract are from the arti- cle by Jacoba Madigan- Stretton, Dierdre Mik- kelsen and Elham Assadi Soumeh, ‘Multienzyme super-dosing in broiler chicken diets: the implica- tions for gut morphology, microbial profile, nutrient digestibility and bone min- eralisation’.
This study investigated the impact of the appli- cation of super-dosing multienzymes on gut mor- phology, microbial profile, nutrient digestibility, and bone mineralisation in broiler chickens.
Microbial profiling re- vealed diverse communi- ties, however they did not significantly differ be- tween treatment groups.
Results found that super- dosing multienzymes im- proved nutrient digestibil- ity, maintained a diverse microbial population, and tended to increase the overall villi morphology.
One bird per pen was slaughtered at day 42 and gut morphology, cecal mi- crobial profile and nutrient digestibility were studied.
In conclusion, based on the outcomes of this study, a dose rate of 700g/t Natuzyme is recom- mended to improve gut morphology and nutrient digestibility, and promote unique microbes which aid in feed efficiency.
Bone mineralisation was not affected by increasing multienzyme doses.
Additionally, the present study found three bacteria that were unique to mul- tienzyme inclusion at a super-dose level.
Optimising gut health has a large impact on nutrient digestibility and bioavailability, and super- dosing feed enzymes may be one solution to achieve this.
