Early summer deworming of nursing calves

Parsons, Kansas — Five deworming trials were conducted at the Eastern Research Station located near Haskell, Okla., during the 1990’s. Crossbred cows and their Charolais sired calves were sorted by sex of calf, calf age and cow age, then randomly allotted to one of four treatments: 1) non-dewormed control, 2) deworm calf only; 3) deworm cow only; and 4) deworm cow and calf. Two or three treatments were applied each year including one control group. Each treatment was applied two or three years. Cows and calves were individually identified and weighed in early June. Treated animals received label-recommended dosages of a commercially available pour-on. Pairs grazed in rotation seven bermudagrass pastures overseeded with clover at a stocking rate of two acres per cow-calf pair during the 144 to 181-day trials. Initial studies indicated that a low worm infection rate was present in the first two years. At that time fecal egg counts ranged from 0 to 28 eggs per three gram sample of feces.

Deworming cows in late spring had no significant effect on cow summer weight gains up until calf weaning time.  Treating cows but not their calves resulted in a small advantage in average daily calf weight gains (0.1 pound/day); while treated spring-born calves had significantly greater daily weight gains (0.14 pound/day) while nursing non-treated cows. In other words, just deworming the calves resulted in a 21 pound weaning weight advantage over non-treated controls. Treated calves nursing treated cows had significantly greater average daily weight gains (0.17 pound/day) than the untreated calves nursing untreated cows. Over the approximate 150 day period this weight gain advantage would total about 25 pounds additional weaning weight to calves in this treatment group. In this series of studies, deworming spring-born nursing calves in early summer resulted in summer weight gains of 21 pounds. Deworming both cow and calf resulted in an increased summer weight gain of 25 pounds versus non-treated controls (or four pounds more than when the calf alone was treated.)

In these studies, reproductive performance was quite high for both treated and non-treated cows, and no difference was noted. Different results may occur in different climates and under different stocking rates. In 2013, with some thin cows going out on short, overgrazed pastures, deworming the cow may have a greater impact on cow performance. £

  • Stockers015.jpg Pressure builds on cattle prices

    With boxed beef prices down sharply from the second rollercoaster high of the year, fed cattle prices may have peaked seasonally.  
    Fed prices are currently holding mostly steady near $150/cwt. but will likely decrease into May as fed cattle marketings increase seasonally. Cattle slaughter typically increases from April through May to seasonal peaks in June.

  • calving-season_ksu.jpg Shortening breeding and calving seasons

    Calves born in the first 21 days of the calving season are often the heaviest in their contemporary group at weaning, and that advantage often carries through to harvest, if the producer retains ownership.

  • heifers-peel-052_fixed.jpg Late spring adds to cattle challenges

    A myriad of factors are at work in cattle and beef markets now. Spring has arrived according to the calendar but it isn’t obvious yet in many parts of the country. Cold weather continues to delay grass green-up in many regions in a fashion that is reminiscent of last year.

  • Beef Talk: Are your cows ready to rebreed?

    The question of the day: Are the cows ready to breed? I hope the nutritional plan is in place and the cows are doing fine. Although nutritional adjustments can be made if needed, precalving should be a time of contentment for the cow, so all she needs to do is enjoy late-term pregnancy.

    I often get the question “How much should I pay for a bull?” My first answer is “Whatever the market will bear.”

  • cull-cows.jpg Slaughter cow market following seasonal pattern — only more so

    Boning cow prices in Oklahoma City were reported at just over $102/cwt. in the first week of March. This level suggests that March slaughter cow prices will exhibit a more than seasonal price increase.

    For a disease that’s not contagious, anaplasmosis sure gets around.
    Speaking to a whole passle of beef producers at last week’s Animal Health Day in Independence, Kan., K-State Veterinarian Larry Hollis urged area cattlemen to get the costly disease in their sights.

    Arkansas cattle numbers are recovering nearly two years after the start of a drought that caused $128 million damage to the state’s beef industry, while national numbers plummet to their lowest levels in more than 60 years.
