Research By Year


The effect of beta-hydroxy-beta-methylbutyrate on growth, mortality, and carcass qualities of broiler chickens.

HMB decreased mortality by up to 72 percent and showed small increases in muscle growth in broiler chickens (summary of five studies conducted at three sites).

Effects of beta-hydroxy-beta-methyl butyrate on performance and carcass quality of feedlot steers.

HMB decreased subcutaneous fat depots in cattle but increased intramuscular fat in the longissimus muscle.

Colostral milk fat percentage and pig performance are enhanced by feeding the leucine metabolite beta-hydroxy-beta-methyl butyrate to sows.

Three studies are summarized and show that feeding HMB increased milk fat percentage, baby pig growth and tended to increase survivability of baby pigs.

Dietary supplementation of ß-hydroxy-ß-methylbutyrate improves catch-up growth in underfed lambs

HMB improved growth in lambs that had previously limited feed intakes and slower growth rates.

Decreasing male broiler mortality by feeding the leucine catabolite ß-hydroxy-ß-methylbutyrate

HMB decreased nonspecific mortality during conditions of environmental extremes in male broilers.

The effects of the leucine catabolite ß-hydroxy-ß-methylbutyrate on the growth and health of growing lambs

HMB improved growth, immune function, and decreased the severity and incidence of a natural pox virus infection in sheep.

Distribution of the leucine metabolite ß-hydroxy-ß-methylbutyrate in foods and feeds

HMB is found in most foods in low levels but is four to ten times higher in alfalfa, poultry byproducts, and certain vegetables.

Effect of feeding ß-hydroxy-ß-methylbutyrate on immune function in stressed calves

HMB fed to calves injected with ACTH partially prevented the resulting cortisol-induced decrease in immune function.
