Methionine Requirement and Commercial Methionine Sources in Growing Pigs
Methionine is a limiting amino acid in commercial swine diets and commonly supplemented as dry DL-methionine (DL-Met, 99%) or as liquid DL-methionine hydroxy analogue-free acid (liquid MHA-FA, containing 88% of active substance). New and intriguing research has been published in poultry and swine as to what is the nutritional effectiveness of liquid MHA-FA relative to DLMet, and what are the re...
متن کاملEfficacy 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 کاملBioavailability of D-methionine relative to L-methionine for nursery pigs using the slope-ratio assay
This experiment was conducted to determine the bioavailability of D-methionine (Met) relative to L-Met for nursery pigs using the slope-ratio assay. A total of 50 crossbred barrows with an initial BW of 13.5 kg (SD = 1.0) were used in an N balance study. A Met-deficient basal diet (BD) was formulated to contain an adequate amount of all amino acids (AA) for 10-20 kg pigs except for Met. The two...
متن کاملEffects of dietary methionine and lysine sources on nutrient digestion, nitrogen utilization, and duodenal amino acid flow in growing goats.
This study investigated the effects of supplementation of various sources of Met and Lys on nutrient digestion, N utilization, and duodenal AA flows in growing goats. Four 4-mo-old Liuyang Black wether goats were used in a 4 x 4 Latin square experiment and were assigned to 4 dietary treatments: (1) control, (2) control + lipid-coated Met-Zn chelate and Lys-Mn chelate (PML), (3) control + Met-Zn...
متن کاملBioavailability of different dietary supplemental methionine sources in animals.
Dietary methionine is indispensable for animal maintenance, growth and development. L-methionine (L-Met), and its synthetic forms DL-methionine (DL-Met) and 2-hydroxy-4 (methylthio) butanoic acid (HMTBA) are common supplemental methionine sources in animal diets. There are different characteristics for cellular absorption, transport, metabolism and bio-efficiency between these three dietary met...
