Cow cooling on commercial drylot dairies: A description of 10 farms in California
modity produced in California, the top dairyproducing state in the country (Sumner et al. 2015). In the western United States, 30% of dairy farms keep about 1.8 million lactating cows in drylots (open, dirt-based pens), where sheltered areas may or may not be available (USDA 2016). Drylots are thought to be advantageous, in comparison to other intensive housing systems (e.g., free-stalls, concr...
متن کاملImpact of cow size on dry matter intake, residual feed intake, metabolic response, and cow performance.
Thirty-eight Angus-cross beef cows were used to evaluate differences in DMI, residual feed intake (RFI), and endocrine markers on the basis of cow size and RFI ranking during 2 stages of production. Cows housed in individual pens (2.2 × 9.1 m) were fed, over a 70-d feeding period, 30% Bermuda grass hay and 70% ryegrass baleage diet during lactation (LACT) and a 100% ryegrass hay diet during pos...
متن کاملTechnical note: Validation of a system for monitoring individual feeding behavior and individual feed intake in dairy cattle.
The objective of this study was to validate an electronic system for monitoring individual feeding behavior and feed intake (Intergado Ltd., Contagem, Minas Gerais, Brazil) in freestall-housed dairy cattle. No data have been published that validate either the behavioral measurement or the feed intake of this system. Feeding behavior data were recorded for 12 Holstein cows over 5d using an Inter...

Prediction of genetic values for feed intake from individual body weight gain and total feed intake of the pen.
Records of individual feed intake (FI) and BW gain (GN) were obtained from the Germ Plasm Evaluation (GPE) program at US Meat Animal Research Center (USMARC). Animals were randomly assigned to pens. Only pens with 6 to 9 steers (n = 289) were used for this study (data set 1). Variance components and genetic parameters were estimated using data set 1. Estimated genetic values (EGV) for FI were c...
