In broilers, 2-hydroxy-4(methylthio) butanoic acid (HMTBA) can elicit a different dose response relative to dl-Met (DLM) such that birds could have lower gain responses at deficient TSAA concentrations but greater gain responses at maximum response concentrations. Two experiments tested if the 2 Met sources have a different dose response in 1-d-old turkeys using a 2 x 4 factorial plus a control...

OBJECTIVE The study was conducted to evaluate the effects of different methionine (Met) sources on production performance, reproduction performance, egg quality and serum biochemical indices in broiler breeders. METHODS After receiving a basal diet (containing 0.25% Met) for a 2-wk pretreatment period, a total of 360 39-wk-old Lingnan yellow broiler breeders were randomly allocated to four tr...

A correspondence between the problem of twodimensional digital least-metric (DLM) tting and data detection in serially concatenated systems in digital communication theory is described. Nearly optimal detection algorithms based on recent advances in iterative detection/decoding are applied to the DLM problem for two applications in digital image compression. The rst application is least squares...

One experiment was conducted to study the effect of excess dl-methionine (DLM) and dl-2-hydroxy-4-methylthiobutanoic acid free acid (dl-HMB-FA) on duck growth. One-day-old male white Pekin ducklings were fed common starter diets from hatch to 21 d of age and then fed the experimental diets from 21 to 42 d of age. Three hundred twenty 21-d-old birds were allotted to 40 raised wire-floor pens wit...

The literature provides several statistical models to explain dengue incidence. However, there is disagreement as to the real contribution of models based on climate factors or models based on relative variables to combat the vector, because their variability fails to provide a satisfactory statistical explanation for the behavior of dengue incidence. Distributed lag models (DLM) posit that a v...

In this paper, we present eecient trap-escaping strategies in a search based on discrete Lagrange multipli-ers to solve diicult SAT problems. Although a basic discrete Lagrangian method (DLM) can solve most of the satissable DIMACS SAT benchmarks eeciently, a few of the large benchmarks have eluded solutions by any local-search methods today. These diicult benchmarks generally have many traps t...

A novel methodology, the double layer methodology (DLM), for modeling an individual's lifestyle and its relationships with health indicators is presented. The DLM is applied to model behavioral routines emerging from self-reports of daily diet and activities, annotated by 21 healthy subjects over 2 weeks. Unsupervised clustering on the first layer of the DLM separated our population into two gr...

A discriminative bilinear language model (DBLM) estimated on the basis of Bayes risk minimization is described. The discriminative language model (DLM) is conventionally trained by using n-gram features. However, given a large amount of training data, the DLM is not necessarily trained efficiently because of the increasing number of unique features. In addition, though some of the n-grams share...

A biological experiment of six weeks duration, followed by several laboratory investigations were carried out to study the effect of designer layer mash (DLM) containing full fat flaxseed, oil rich sardine fish, Holy Basil leaf meal (BLM), vitamin E and Organic selenium (Sel-plex), on haematology of layers. Both designer diet and BLM had significant effect on haematology of layers. They also ex...

Two sources of methionine (Met) activity are frequently used in commercial feed formulation: DL-2-hydroxy-4-(methylthio) butanoic acid (HMTBA), most commonly available as an 88% solution with 12% water; and DL-methionine (DLM, 99% powder). Despite the fact that both compounds have been in commercial use for over 50 yr, controversy and confusion remain with respect to their relative bioefficacy ...
