Dear Dr. Prasad. I got curious about the maximum energy release of 125-150 kcal/kg, whatever the combination of additives and diet composition. Where does this number comes from?

@Dr. Rajendra Prasad Vemana I really do not agree with this very "broad brush" description. If I consider that sNSP content of maize is only 20% that of wheat, I cannot see in any way that an enzyme that MIGHT contribute 100 kcal energy sparing in a wheat-based diet can provide anything close to 100 kcal in a maize-based diet - simply not enough substrate! I would use 20 - 30 kcal maximum such die ...

@Mike Stahl Dear Mike. Actually, trials demonstrate the same bioefficacy level in all types of livestock, including Laying hens. There are numerous laying hen experiments - both in field conditions and at research facilities - confirming that 100 parts of MHA can be replaced by 65 parts of DL Methionine with no loss in performance but significant savings in feed cost. I can share these with you if ...

A study published in 2003 comparing the nutrition and genetics of broilers from 1957 to a commercially available broiler strain estimated that within less than 50 years of development, broilers were reared to maturation in a third of the time (Havenstein et al., 2003). This shows clear evidence that improvements in genetics, nutrition and management of rearing meat producing chickens has continual ...

INTRODUCTIONGenetic selection in poultry has progressed continuously since the early 1960s, resulting in faster growth rates and higher meat production (Havenstein et al., 2003a,b). Over the past 60 years, body weight gain has increased fourfold from 1957 to 2005 with a simultaneous 50% reduction in feed conversion ratio and 79% higher Pectoralis major yield in males and 85% in females (Zuidh ...

DL-Methionine (DL-Met, 99%) and liquid DL-2-hydroxy-4-methylthio butanoic acid (methionine hydroxy analogue-free acid, MHA-FA, 88%) are often used in commercial poultry feeds to meet the requirements for Methionine+Cysteine (M+C). However, differences in chemical properties and absorption decrease the relative bioavailability value (RBV) of MHAFA, which corresponds to 65% of DL-Met for performance ...

Dear All, coming back to egg mass. Good to see increases, but any thoughts on why positive control was so low? At 74 weeks, Nick Chick would be expecting about 63 - 64 g egg mass, not the 51 recorded...? MPS

Dear Alireza, thank you for confirming the concept by an additional data set. I like to pronounce, that validating the equivalency of DL-Met and the methionine hydroxy analogue at 65:100 replacement ratio not only results in same animal performance but also in considerable cost savings when using DL-Met provided the price ratio between mentioned products is not 65%, which means the price of the hy ...

there is nice report. We replaced in diet 65 part of DL-MET with 100 part of MHA in trial on 6000 broilers in iran. Results indicated that body weight and FCR were the same in both groups confirming 65% RBV of MHA.
