ADISSEO OH-Methionine and DL-Methionine: same efficacy to sustain growth performance and feather
development of Cherry Valley ducks A recent publication on methionine sources comparison in ducks:
Zhao et al. 2018 (Poultry Science) has been presented by Dr. Dolores Batonon Alavo at the European Poultry Conference held in Dubrovnik, Croatia on the 20th September 2018. This study was performed on 630 Cherry Valley ducks reared
from 1 to 42 days in China. Diets were based on corn, wheat and soybean meal and formulated according to NRC (1994) recommendations. Treatments consisted in a basal diet deficient in TSAA and eight supplemented treatments with either DL-Methionine or OH-Methionine. For the supplemented treatments, equimolar doses of methionine added to the basal diet from 0 to 21 d (0.04, 0.12, 0.16 and 0.20%) and from 21 to 42 d (0.0.2, 0.06, 0.10 and 0.14%). OH-Methionine was found as efficient as DL-Methionine to
sustain Cherry Valley ducks’ growth performance concerning body, carcass, breast or feather weights. In addition, methionine efficacy determined as the extra
methionine intake per extra weight gain shows similar values between DL-Met and OH-Met. The calculation of bio-efficacy on this criterion confirms that DL-Met and OH-Met have the same bio-efficacy on body weight gain. No significant difference of feather weight or yield was observed
between DL-Met and OH-Met independently to the age. The two methionine sources promote feather growth in the same way. This study shows that OH-Methionine is 100% efficient to
sustain growth performance and feather development of Cherry Valley ducks. Reference: Zhao L, Zhang N-Y, Pan Y-X, Zhu L-Y, Batonon-Alavo DI, Ma L-B, Khalil MM, Qi D-S, Sun L-H (2018). Efficacy of 2-hydroxy- 4-methylthiobutanoic acid compared to DL-Methionine on growth performance, carcass traits, feather growth, and redox status of Cherry Valley ducks.

Crystalline dihydrate dicalcium phosphate, with a high chemical purity and proven P-digestibility
Dicalcium phosphate with a high P-digestibility for use in compound feed as well in mineral feed
Monodicalcium phosphate that fits all species and all purposes
Monocalcium phosphate with a high P-digestibility and reverse Ca:P ratio
Dicalcium phosphate with a high mineral content, to be used in cattle mixtures, lick blocks
A feed grade monoammonium phosphate with the highest P-content, for ruminants (NPN).
Because of the high P-solubility and P-digestibility especially recommended for use in aquaculture
Highly soluble and thus available magnesium, for ruminants
SolidaCal, based on sea shells, is a natural slow release calcium
source for laying hens. SolidaCal Buf is a cost effective natural rumen buffer. Exal - sepiolite clay- registered as a pellet binder, it is also used as
an inert carrier for premixes and mineral feed, due to its low reactivity. Also used because it’s high moisture absorption capacity to keep litter drier to reduce breast blisters and hock burn. SPLF is a further refined form of sepiolite that is used to improve the flow characteristics of liquid pig feeds. Aliphos also offers micro-encapsulated nutrients for ruminants,
like very efficient rumen protected selenium (Se). Microencapsulated organic acid, essential oils and plants extracts are available for monogastrics. Glystar and Glystar Forte are the Aliphos ranges of pure metal (bis)-glycinates. These organically bound trace metals are highly
