The objectives of this controlled study were to compare the effects of 2 different formulations of recombinant bovine somatotropin (rbST) on milk yield, milk composition (fat and protein), milk somatic cell count, and body condition score (BCS) among dairy cattle in a large commercial herd. Regulatory approved 500-mg zinc sesame oil base rbST (ZSO-rbST; Elanco Animal Health, Greenfield, IN) and vitamin E lecithin base rbST (VEL-rbST; LG Life Sciences, Seoul, South Korea) formulations were… Expand
Slow Release Rbst Administration During the Transition Period on Performance and Blood Cell Counts of Dairy Cows
TLDR
It is supported that rbST supply during transition period improves performance of dairy cows that is partially related to improvements in metabolism. Expand
Detection of methionine- and alanine-recombinant bovine somatotropins and their induced antibodies in serum and milk of cows suggests blood-milk barrier specificity for these compounds.
TLDR
E elimination patterns show that, for enforcement purposes, the detection of rbST-induced antibodies in tank milk can serve to screen for rb ST administration, and subsequent confirmatory serum analysis by LC-MS/MS is needed to identify whether Ala-rbST or Met-rb ST has been used. Expand
Effects of Body Condition Score Changes During Peripartum on the Postpartum Health and Production Performance of Primiparous Dairy Cows
TLDR
A lower BCS in primiparous cows during peripartum influences the NEFA and BHBA concentrations, hormone levels, postpartum health, and production performance. Expand

Administration of recombinant bovine somatotropin to dairy cows for four consecutive lactations.
TLDR
Milk yield, efficiency of feed utilization, and body weights were enhanced in cows injected with bST for four consecutive lactations as well as Pretreatment milk yields in yr 2, 3, and 4 were not affected by previous bST treatment. Expand
Dose titration of sustained-release recombinant bovine somatotropin in lactating dairy cows.
TLDR
Data suggest that 350 mg of bST/14 d increased yields of milk and FCM with no adverse effects on DMI, health, or reproduction in dairy cows. Expand
EFFECTS OF A 28-DAY SUSTAINED-RELEASE FORMULATION OF RECOMBINANT BOVINE SOMATOTROPIN (rbST) ADMINISTERED TO COWS OVER TWO CONSECUTIVE LACTATIONS
TLDR
Responsibility in milk and milk component yield was positive and very consistent for multiparous cows between trials, and primiparously cows responded in both lactations with the same numerical magnitude as multiparrous cows but with higher variability. Expand
Long-term evaluation of a prolonged-release formulation of N-methionyl bovine somatotropin in lactating dairy cows.
TLDR
Within a 14-d injection interval, animals treated with sometribove displayed a cyclic pattern in milk yield, but a similar pattern was not evident in feed intake, and milk content of lactose, fat, ash, and Ca was not affected, but protein and phosphorous were slightly greater in milk from somet ribove-treated cows. Expand
Effects of recombinant bovine somatotropin (rbST) and season on plasma and milk insulin-like growth factors I (IGF-I) and II (IGF-II) in lactating dairy cows.
TLDR
Although milk IGF-I and IGF-II concentrations were unaffected by rbST treatment, total IGF-output increased due to increased milk yield, which may be indicative of seasonal differences in the coupling of the somatotropin-IGF axis. Expand
Management and economics of extended calving intervals with use of bovine somatotropin
TLDR
Extended calving interval resulted to fewer calvings, lower incidence of postpartum metabolic diseases, lower veterinary costs, less culling with fewer replacements needed, and an overall improvement in herd life, animal well-being and dairy farm profitability. Expand
Meta-analysis of the effects of sometribove zinc suspension on the production and health of lactating dairy cows.
TLDR
Results indicated that rbST-Zn administration to dairy cows effectively increases milk production with no adverse effects on cow health and well-being. Expand
Effect of a prolonged-release formulation of N-methionyl bovine somatotropin (sometribove) on milk fat.
TLDR
Administration of bST increased production of milk, total fat, and all milk fat components measured, andMelting properties of milk fat were influenced greatly by stage of lactation, and bovine somatotropin did not cause any changes in composition or physical properties of Milk fat that were outside the range of normal variation. Expand
Effect of a prolonged-release formation of N-methionyl bovine somatotropin (sometribove) on milk composition.
TLDR
A cyclical pattern of milk production, component production, and composition within each 14-d injection interval was observed, suggesting that a diminishing amount of bST was delivered during the latter third of each injection interval. Expand

TLDR
Annual farm-level data from New York dairy farms from the years 1994 through 2013 were used to estimate the cost effect from bovine somatotropin (bST) using propensity score matching, which represented a cost savings of 5.5% per kilogram of milk produced. Expand
