Efficacy of DL-methionine hydroxy analog free acid and DL-methionine as methionine sources for pigs.
Two experiments were conducted to evaluate the efficacy of dietary DL-methionine hydroxy analog-free acid (MHA-FA, 88%) compared with DL-methionine (DLM, 99%) as Met sources in pigs. In Exp. 1, a total of 245 crossbred pigs (initial BW of 6.4 kg [SD = 0.5]) were allotted to 7 treatments in 7 replicates for an experimental period of 28 d. The basal diet (BD) was formulated to contain 17.5% CP an...
متن کاملComparing Bio-efficacy of Liquid DL-methionine Hydroxy Analogue Free Acid with DL-methionine in Broiler Chickens
The present experiment was conducted to assess the efficacy of methionine hydroxy analogue free fatty acid (MHAFA) in comparison to DL-methionine (DL-Met) utilizing day-old commercial broiler chicks (n=300). The chicks were randomly distributed into 30 groups of 10 chicks each. Three dietary treatments, viz. D1-maize-soybean meal based basal diet (Control), D2control diet supplemented with DLme...
متن کاملBiological Effectiveness of Methionine Hydroxy-analogue Calcium Salt in Relation to DL-Methionine in Broiler Chickens
Two feeding trials were conducted to assess the relative bioavailability (RBV) of methionine hydroxy analogue calcium salt (MHA-Ca) in comparison to DL-methionine (DL-Met). Male Ross 308 (1-38 days) and Cobb 500 chickens (1-42 days) were used in studies 1 and 2, respectively. Experimental diets based on wheat and soybean meal or sorghum and soybean meal were fed during three phases. In both exp...
متن کاملThe Relative Effectiveness of Liquid Methionine Hydroxy Analogue Compared to DL-methionine in Broilers
The present experiment was conducted to assess the efficacy of liquid methionine hydroxy analogue-free acid (MHAFA) in comparison to DL-methionine (DL-Met) in broilers. 567 day-old Avian chicks were divided into 7 treatments with 5 replicates of 16 birds each. During the 35d (7-42 d) experimental periods chicks were given two basal diets. From 7 to 21d of age, a starting basal diet containing 1...
متن کاملNutritional value of methionine hydroxy analogue calcium salt compared with both pure DL- methionine and diluted DL-methionine with 65% purity
Correct use of DL-methionine (DL-Met) and methionine hydroxy analogue calcium salt (MHACa) requires knowledge on their nutritional value which can be determined by multi-exponential regression analysis of dose response data. In order to both examine the biological value of MHACa compared with DL-Met and to validate the mathematical approach a dose-response trial was performed with graded levels...
