Methionine Hydroxy Analog or Sulfate Supplementation for High Producing Dairy Cows x ABSTRACT Thirty-six Holstein cows were assigned to three rations.
Control rations were supplemented with 25 g/day methionine analog or g/day sodium sulfate. Assignment was by actual or estimated mature equivalent production of the pre- vious by: Cows supplemented with methionine hydroxy analog produced more milk fat (P solids-not-fat were not significantly by: They were then gradually increased in concentrate up to ] kg per day.
Corn silage containing % urea was fed free choice to all cows. Concentrate containing varying amounts of analog was fed for 90 days after parturition. C'ontrol concentrate (0% analog) was fed to all cows between 90 to by: Methionine hyroxy analog fed at 43 g/day decreased dry matter intake to the intake of the sulfur deficient diet without affecting daily milk production.

Infusion of lysine to cows resulted in a daily increase of % in DM intake, % in milk yield, % in milk protein yield, and a % decrease in milk fat yield compared to : Edna Nachtomi, Israel Bruckental.

If true, this means that high producing dairy cows need to be fed protein from sources which have both a good amino acid profile and have resistance to degradation by bacteria in the rumen. Effect of methionine analog was most apparent at low protein as 0 analog cows produced kg fat, required services/contraception, and had days open whereas cows on other treatments Effects of dietary supplementation of methionine and lysine on milk production and nitrogen utilization in dairy cows Article (PDF Available) in Journal of Dairy Science 93(8) August.

Mature Simmental × Angus cows ( cows; ± 7 kg) were utilized to determine the effects of late gestation and early postpartum supplementation of methionine hydroxy analog (MHA) on cow BW, BCS, milk production, milk composition, reproduction, and calf performance until weaning in a fall-calving, cool-season grazing by: 3.
The objective of the study was to compare the effect of feeding mixed chelated minerals (Mn, Cu and Zn) methionine on dairy cow productive performance and milk yield and its components. The trial was conducted with dairy cows across various stage of lactation.
The experimental treatments include chelated minerals (15 mg Zn as Zn Met, 20 mg Mn as Mn Met, 10 mg Cu as Cu Met).Cited by: 4.

Methionine, a required nutrient for cows, has been principally used in dairy rations with the goal of improving milk production or composition. When cows are fed diets enriched with methionine, they respond with an increase in milk volume, an increase in the percentage of protein in the milk, or by a combination of g: analog.
