Drought driven cow culling. Opportunity for replacement heifers in 2023?

The July 1, 2022, beef cow inventory compiled by USDA NASS indicates the national beef replacement heifer inventory is below 5 million head. Unprecedented cow culling is occurring in the southwest due to the ongoing drought conditions. To put that in perspective, the United States has not seen numbers this low since 1972 and 1973 when the national beef replacement heifer inventory hovered around 7 million head. Even in 1965, beef cattle replacement heifer inventories were above 5 million head nationally.

New Jersey reported 5,000 head of beef cattle replacements in 1973 and only 2,500 head in 2019. With all cattle and calve numbers in 2020 reported at 28,000 head down 2,000 head from 2019, it is probable that state raised beef heifer replacement numbers are below 5,000 head going into the fall of 2022.

What is more contrasting compared to 1973 is the difference in calf crops. In 1973, the national calf crop was estimated at 50 million head. Going into summer of 2022 the calf crop is estimated at 25 million head. With an estimated 5,000 of these 500 lb calves or less in weight coming from New Jersey and only half assumed to be heifers, these heifers have considerable value beyond the feedlot, if they have brood cow qualities.  Maintaining those selected for replacement herd purposes requires considerable attention to body conditioning to grow a weaned heifer to be bred at 15 months to meet industry replacement standards.

To learn more about raising replacement heifers contact Melissa Bravo for a copy of ‘A Checklist For Calving Success.  A first-time heifer is a long-term investment.’

What are replacement heifers worth? The USDA AMS Show-Me-Select Special – Carthage, MO Livestock, Poultry, & Grain May 2022 report is a good example of the criteria that brings $1450.00 to $3,100 bred replacement heifer sale prices. Remember, these heifers were born, weaned, and fed through 15 months of age on 2019 (conception), 2020 (birth year), 2021 (breeding year) feed prices.

  • All met minimum standards for reproductive soundness, pelvic size, body condition and weight.
  • All immunized including Brucellosis calf-hood vaccination and tested negative for PI BVD.
  • Heifers bred to bulls meeting strict calving ease or birth weight EPD’s.
  • Many were synchronized and artificially bred.
  • Projected calving dates were given.
  • All heifers pregnancy checked within 30 days of sale.
  • Sale animals screened for blemishes, muscle, frame and body condition score, and disposition.
  • Heifers sorted and sold according to calving dates and similar body types.
  • The average price per head was $1913.00. The highest selling lot brought $3100.00 per head.
  • The A.I. bred heifers brought $141.00 more than natural bred heifers.
  • About 40% of the heifers were black, 30% black, white-face, and 30% red.

Salem County Producers: If you would like to host a calf crop evaluation pasture walk for replacement heifer qualities, contact Melissa Bravo at the Salem County Extension Office.

 

 

Can we implement a quick fix for heat stress? 

 After seeing a recent heat stress article appearing in the Plant and Pest Advisory,  I was reminded of the need for heat stress management for animals.  The following article appeared in the pages of the Hoard’s Dairyman magazine.  Steve Martin from DNMCMILK give some good guidelines for managing the dairy herd.  Click on

Heat Stress Management in the Dairy Herd 

to see the article.

MARTIN, DNMCMILK,  July 21, 2022(c) Hoard’s Dairyman Intel 2022

“The best time to strategize about heat stress mitigation is early spring when there is still some frost on the ground in the mornings. Or better yet . . . planning for next summer’s heat abatement plan could be done in the previous fall when the shortcomings of the current cooling strategies are fresh on everyone’s mind. However, that doesn’t mean that when we are in the thick of the summer stress we can’t implement new ideas. The goal during these times may be attempting to maintain feed intake during heat stress.”

Crop progress and sicklebarring palmer greenstalks

Salem County: Two plus inches of June precipitation on the 9th and 12th carried non-irrigated corn and soybean through the month with only trace amounts of precipitation until the 24th when some areas received another half inch.

In exceptionally wet fields, climbing humidity levels on the 13th, 14th, and 15th were high enough to allow for foliar disease development in beans. But the following week of low humidity was less than conducive for disease proliferation until the 22nd through the 25th when humidity levels briefly rose and remained in the high 80’s and 90’s for three days, before dropping nicely to the mid 60’s the last two days of June. However, wind speeds of 15 to 25 mph from June 13th to June 19th wicked moisture out of corn and soybeans leaving the crops in a moisture deficit.

This is confirmed in ‘The Evaporative Demand Drought Index’ (EDDI) monitoring tool for South-Jersey. This tool created by the NOAA Physical Science Laboratory is an indicator of both rapidly evolving “flash” droughts and sustained droughts. “EDDI can offer early warning of agricultural drought, hydrologic drought, and fire-weather risk.”

Pest pressure: Producers should monitor beans for Japanese beetle, green stink bug and grasshopper feeding going into July and be alert to excessive damage from flea beetles on crops stressed from wind evaporation. Palmer amaranth is exceptionally tolerant to droughty conditions and thrives under stresses that wilt other pigweed species. Shattercane and johnsongrass are both warm-season grasses that also thrive under these weather conditions.

Mechanical options: In addition to chemical control options, if droughty evaporative weather persists, producers should consider manually removing seedhead stalks to protect maximum yield projections in soybeans. The ideal mechanical tool to do this would be a front mounted sickle bar mower. Do-it-yourself fabricators maybe interested in this attachment created specifically to deal with palmer amaranth by a Kansas farmer. (A cooperative build, purchase, may be a good investment for combine and spray rig operators in the County). https://www.rowshaver.com/

Forecast: Going into this weekend, the 24-hour precipitation forecast for

New Jersey anticipates a tenth of an inch to half inch of rainfall for most of Salem County through July 3 and much-needed swath probable for the northern counties where drought conditions the last seven days are 51% to 75% below normal.

Crop Progress and Hessian Fly Sightings

Hessian Fly From Dough Stage Wheat

June 8, 2022 Salem County, NJ

Salem County has experienced nearly two weeks of ideal temperatures in the mid 80’s to low 90’s allowing for a considerable amount of soybean acreage to be planted, and hay acreage harvested. Rye for grain harvest is nearly complete and barley will soon follow. With a 72-hour forecast of one inch to one and a half inch expected, many producers have switched back to planting as the window to make dry hay closes.

Corn: Early planted corn is near canopy and in very good condition. Surface moisture is adequate but at this stage of rapid stem elongation, rain is needed to replenish the two inches of rain received at the end of May but less than a tenth of an inch in the last week. Overall, most of Salem County received in excess of 12 inches of rain in the last 90 days ending June 6, which is over an inch and a half more than the average for this period of the growing season and substantially more than the drought stressed crops in Cape May County that are experiencing a 75% deficit in moisture for the last seven days. Corn planted into standing rye and other late terminated cover crops is lagging behind tilled fields due to moisture competition and carbon sink, but overall flushes of seedling broadleaves are not present indicating preemergence programs are working effectively.

Soybeans: Full season soybean planting is nearly complete. Emerged beans are ahead of seedling flushes of pigweeds but behind giant ragweed in areas where ragweed is present. Expect amaranth species weed pressure to increase significantly after this weekend’s forecasted rain.

Wheat:  Wheat is drying down rapidly and in overall good to excellent condition. In areas where irrigated wheat is already yellow and evidence of wind damage is visible, Hessian Fly is the most likely culprit as seen in this photograph taken in a dough stage field. Flowering canada thistle seen in wheat that will be double cropped with soybeans should be de-headed to prevent seed dispersal prior to harvesting. In enlarging patches, consider a spot-treatment (sacrificing soybean) of a growth regulator herbicide if prior treatments of glyphosate products have not limited spread. 

About Hessian Fly: Mayetiola destructor (Say) is a grain pest in the Cecidomyiidae family. It is a major cause of wheat yield reduction around the world. The fly forms galls on the underside of wheat leaves that protect the feeding larva from efficacious applications of insecticides. In addition to wheat, Hessian fly can be found in rye, barley and in brome grasses (and reedscanary). Bromes are a major composition of the grasses in this area. Egg hatched occurred when temperatures were above 50 degrees earlier this season.

Seven Day Precipitation Departure From Normal

https://www.weather.gov/marfc/Precipitation_Departures

If producer’s noticed patches of dark green areas of wheat (barley) in the same fields now infested with flies or where lodging is increasingly evident, these are an indicator of where the larva were pupating.

Larval feeding after stem elongation causes lodging. Feeding damage can also cause failure to produce a seed head, and a reduce seeds per spike and light test weight. – Journal of Integrated Pest Management, September 2018 article.

The adult swarm seen today are emerging after fourteen days of ideal weather above 70 degrees Fahrenheit. Now that flies are present, they will lay eggs over the course of the next week.

 

Due to climate change, it is possible that there could be three emergences of Hessian Fly this year. Southern states see as many as six generations. Generally, in northern states past recommendations have suggested the fly has an emergence in the spring and again in the fall. But in southern states emergences occur in multiples of one, two three in spring, and again in fall. Which is where management strategies come into play. Knowing the number of emergences in our area can help producers calculate if delayed planting will assist with controlling a two brood a year emergence or if it is unlikely to help with multiples of brood emergences. Wind plays a major role in dispersal from infected fields to non-infected fields. Due to cover crop program planting dates for small grains, producers with Hessian Fly issues should talk to their local NRCS office to make sure program planting dates take into account the local Hessian Fly Free dates for fall of 2022.

What to do now: Producers can identify Hessian Fly by looking for swirling clouds of insects that look like white smoke coming out of the wheat canopy. Swatting the swarm will trap flies on the palm of the hand for easier identification. The female fly has a distinctive orange striping to her abdomen. Hessian flies are orange and black banded compared to the overall all orange appearance of wheat midges.  At this stage, the flies have already pupated through the larval stage, which already damaged the wheat crop by tunneling into the stems. Most likely lodging is evident nearby.

What producers can do to plan for next year: Hessian fly was most likely introduced to North America in infected straw bedding. Straw from infested fields may still contain larva. The fly and larva are not considered a pest of stored grain. The larva pupate in the axis of the leaf stem. Cutting straw stubble below the leaf nodes and removing it from the field may help in management as the Hessian Fly larva overwinter inside a flax-seed like cocoon (puparia) at the base of infected plants. Plant resistant cultivars, delay planting dates if this year’s infestation is associated with an earlier planting date, destroy volunteer wheat, and manage brome grasses in field edges and within field when possible.

Hessian Fly Free Planting Dates in Southern New Jersey: “In Maryland, plant wheat following the Hessian fly-free date for your area. This date is approximately September 30 for the Hagerstown area and becomes progressively later as you move from the south and east in the state. The fly-free date is October 13 on the Lower Eastern Shore.” – Read more in 10 STEPS TO PROFITABLE WHEAT PRODUCTION in the Maryland Agronomy News.

Additional considerations for producers planting winter wheat – double crop soybeans-winterwheat: Growers should avoid planting wheat into last season’s wheat stubble. Continuous no-tillage, wheat-double-cropped-soybeans may result in severe problems and should be avoided in Hessian fly problem areas.” – https://www.farmprogress.com/grains/hessian-fly-resistance-threat-southeast-wheat
