Effect of feeding two different forms of supplemental methionine on the lactation performance and health status of dairy cows
The objective of this experiment was to assess the effect of a newly developed form of methionine – isopropylester 2-hydroxy-4 (methylthio) butanoic acid, called MetaSmart on the lactation performance, in particular the production of milk protein, and on the physiological status of dairy cows. At the same time, the efficiency of this supplement was compared with ruminally protected form of meth...
متن کاملLactation performance and serum biochemistry of dairy cows fed supplemental chromium in the transition period
This study was conducted to evaluate the effect of supplemental chromium on performance and blood serum biochemistry of dairy cows. Thus, 20 multiparous Holstein cows (parity 3) were equally divided into two groups, group one (control), which received no chromium supplementation and group two (treatment) which received 5 g/day chromium methionine from week 5 prior to parturition until 12 weeks ...
متن کاملAssessing Transition Cow Management and Performance
Introduction In order to achieve high reproductive efficiency and high milk production, herds must properly manage the entire non‐lactating period and early lactation. We refer to this time period as The Vital 90TM Days and it begins approximately 60 days before calving and continues through the first 30 days of lactation. During this time, dairy cows are exposed to a series of biological and p...
متن کاملImpacts of Supplemental Glucogenic Precursors and Cow Age on Postpartum Range Cow Performance
Altering nutrient partitioning after calving from milk production to positive energy balance may improve reproductive performance. A 2004 study conducted at the Corona Range and Livestock Research Center evaluated responses of 2(n = 17), 3(n = 23), and 4-yr-old (n = 31) postpartum cows grazing native range (11.3% CP and 80% NDF, OM basis) to 3 protein supplements with increasing glucogenic pote...
متن کاملSupplemental oxygen needs during sleep. Who benefits?
The physiologic changes that occur in ventilation during sleep contribute to nocturnal oxygen desaturation in those with lung disease. Nocturnal supplemental oxygen is often used as therapy, although convincing data exist only for those who are hypoxemic both during sleep and wake. Ongoing trials may help address whether oxygen should be used in those with only desaturation during sleep. If use...
