Streszczenie:

In New Zealand, beef-breeding cows are required to wean a calf every year, and the weight of calf at weaning is a major driver of the efficiency of the breeding cow. Weaning weight can be increased by increasing milk yield of the cow such as by incorporating dairy breed genetics into the breeding cows, and by having early born calves which are, therefore, older at weaning. This experiment examined postpartum anoestrous interval and pregnancy rate to rebreeding in 109 beef-breed and beef-cross-dairy breed first-lactation cows suckling their own calves. Cows with a Jersey component had a shorter

Cattle grow and shed fibre which assists them adapt to seasonal changes in the environment. In the absence of cattle fibre production data for southern Australia, Angus, Hereford, Simmental and Limousin cows and crosses between these breeds grazing perennial pastures at Hamilton, Victoria were sampled in late winter. The fibre-growing area on the sides of cattle was measured, fibre sampled at the mid-side site and the sampling area determined. Fibre was tested for fibre diameter distribution, clean washing yield and fibre length measured. Cows were 3–7 years of age, liveweights were 412–712 kg

Systemic infection of mature beef cows with Salmonella typhimurium resulted in death of cows, abortions, and premature births.

The source of the salmonella was not determined.

Abstract Open beef cows account for between 15 and 30% of a spring-calving cow/calf operation’s annual revenue; however, most producers commonly sell open cows at weaning when prices are at a seasonal low. A three-year (2015–2018) study was conducted using open beef cows (n = 244) from a spring-calving herd in south-central Oklahoma. The objective of the study was to determine whether or not the net return of retaining, feeding, rebreeding, and marketing rebred cows was greater than the revenue from selling open cows at weaning. Each year at weaning, open cows were sorted into Thin or Moderate

The objective was to evaluate the development and reproductive performance of beef cows of different body weights at calving were evaluated. Milk yield and calf production efficiency were assessed in secundiparous Braford cows classified at calving according to weight as Light (325.2±3.7 kg), Moderate (347.7±4.0 kg), and Heavy (384.2±4.1 kg). Heavy cows had higher total milk yield than Light cows, but did not differ from Moderate, reflecting in calves weighing at weaning 82.1, 76.6, and 76.9 kg, respectively. Differences on pregnancy rates for Light (90.0%, 18 pregnant cows/2 of eligible cows)

In two 12 mo trials, mature beef cows (n=136) grazing tall fescue pastures were used to compare estimates of forage quality and animal performance. Forage quality was estimated by proximate analysis of forage samples (FOR) or by near infrared reflectance spectroscopy of fecal samples (FNIR).

An external marker, Ytterbium, and an internal marker, indigestible neutral detergent fiber (INDF) were used to estimate organic matter intake, fecal output and digestibility. In addition to samples taken during the trials, blood samples and hand plucked forage samples were taken monthly for 11 mo prior to the tria

Streszczenie:

Tall fescue is a widely grown, cool season grass prevalent in the eastern United States that is known for its resistance to abiotic and biotic stresses. A main reason for tall fescue's resistance to these stresses is attributed to the presence of a fungal endophyte. Unfortunately, this endophyte also adversely affects cattle production. Cows consuming the ergot alkaloids produced by these endophytes can exhibit decreased feed intake, growth performance, organ vasoconstriction, and increased rectal temperature. This work is interested in examining how endophyte toxin exposure impacts pregnanc

In the Scandinavian countries it is common practice for all surfaces of civil structures to be inspected at least every 5-6 years. However, due to insufficient funds and a highly competitive market, not all surfaces are inspected at a hand-near distance. Most often, hands-on inspections are performed by foot, using a lift, by boat or by rope access, typically resulting in an extensive time consumption for large structures. These methods have not changed much over the last decades despite the technical development.Since 2012, COWI has been using Unmanned Aircraft Vehicles (UAV

However, various hereditary anomalies caused by gene mutations have been recently recorded in calves produced by some Ayrshire sires. Most of these anomalies were shown to have a recessive inheritance pattern, thus imposing a threat of unpredictable dramatic changes in cattle genotypes under such factors as genetic drift, selection and inbreeding.
