Application Case Studies:
Case Study 1: Enhanced Broiler Performance in Southeast Asia
A large-scale poultry producer in Southeast Asia faced challenges with suboptimal FCR and variable growth rates in their broiler flocks. Traditional methionine supplementation yielded inconsistent results. Upon consultation, our team recommended transitioning a portion of their feed formulation to include D,L-α-Hydroxymethionine Calcium.
- Solution: Implemented 4857 44 7 at an optimized dosage in starter and grower feeds.
- Results: Over a 12-week trial period involving 500,000 birds, the FCR improved by an average of 3.5%, and average daily gain (ADG) increased by 2.8%. Mortality rates slightly decreased, and the producer reported a more uniform flock with improved feather quality. This translated to significant cost savings and increased profitability.
Case Study 2: Improved Milk Protein in Dairy Cows in Europe
A prominent dairy farm conglomerate in Northern Europe sought to enhance milk protein content without increasing overall feed costs or negatively impacting cow health. Traditional methionine sources often proved inefficient due to rumen degradation.
- Solution: Integrated D,L-α-Hydroxymethionine Calcium into the total mixed ration (TMR) as a rumen-protected methionine source.
- Results: After a six-month trial across multiple herds, milk protein percentage increased by an average of 0.15%, and butterfat content saw a marginal increase. Crucially, somatic cell counts (an indicator of mastitis and overall udder health) showed a reduction of 5%, suggesting improved animal well-being. The superior rumen bypass efficiency of d、l-α-hydroxymethionine calcium was key to these results.
