Abstract

The objective was to evaluate the effect of housing type on health and performance of preweaned dairy calves. One hundred calves, Holsteins (HO) or Holstein-Jersey crosses (HJ), were randomly assigned to a Calf-Tel (L. T. Hampel Corp., Germantown, WI) polyethylene hutch exposed to direct sun light...

Abstract

This study was initiated to evaluate performance and patterns of cow traits and blood metabolites of 3 breeds of cows grazing bahiagrass (Paspalum notatum Flügge) pastures in central Florida. Purebred cows (n=411) of either Angus (Bos taurus), Brahman (Bos indicus), or Romosinuano (Bos taurus)...

Abstract

The objectives of this work were to compare reproduction and parturition traits of the Criollo breed Romosinuano as straightbred and crossbred cows with Angus and Brahman, to estimate heterosis and direct and maternal genetic breed effects, and to describe calf loss, cow removals from the project,...

Abstract

The objectives of this work were to compare the Criollo breed Romosinuano as straightbred and crossbred cows with Angus and Brahman in subtropical Florida and to estimate heterosis for size traits of their calves, their own weight, and maternal efficiency traits. Cows (n=404) were born from 2002 to ...

Abstract

Calves born to cows exposed to heat stress during late gestation (i.e., the dry period) have lower birth weight and weaning weight and compromised passive immune transfer compared with those born to dams that are cooled. However, it is unknown if heat stress in utero has carryover effects after...

Abstract

Spring born beef calves (n=568; 177.7 kg±34.0) at three different locations within the state of Florida were used to determine the efficacy of de-worming 90 days prior to weaning in order to achieve heavier weaning weights. Two or three breed types were available at each location and included...

Abstract

The objective of this study was to compare performance and aspects of adaptability attributes of cattle from a Florida Angus bloodline (local source from a mostly closed herd for over 50 yr) to cattle that are representative of modern Angus bloodlines (outside source) in US subtropical conditions....

Abstract

In a series of trials in Florida, crossbred beef females were fed different chlortetracycline (CTC) regimes relative to weaning and breeding to determine effects on fertility. In trial 1, alternately sorted crossbred yearling heifers were either given CTC at 1.1 mg/kg/day for 30 days before natural ...

Abstract

In trials with Stenotaphrum secundatum cv. Roselawn pasture on organic soil, annual forage DM growth increased from 6.06 ton/ac with (a) 200 lb 0:10:20 N:P2O5:K2O/ac to 7.78 ton with (b) 600 lb/ac, while (c) 800 lb/ac did not increase yields further. Annual DM intake by brood cows increased from...
