Calving Ease & First Service Conception Rates

Mark E. Carson BSc. (Agr). MSc., Gencor Herd Reproduction Analyst A difficult calving can effect a cow's performance throughout the entire lactation. An examination of calving ease performance of first lactation cows from five dairy herds shows the impact it can have on first service conception. Dairy Comp 305 calving ease data provided by DHI was compared with first service conception on first lactation cows. Calving Difficulty 1st Service Conception Rates # of First Lactation Cows Unattended or Easy 38% 195 Hard 22% 64 First lactation cows that had an Unattended or Easy Calving (U or E) were found to have a first service conception of 38%, while cows with a Hard Calving (H) had a conception rate of 22%. From these herds, having a trouble-free calving made the cows twice as likely to get pregnant on the first breeding! To reduce calving troubles, work to manage body condition scores, age at first calving and appropriate sire selection. Also, make sure you are providing proper assistance to cows that need help at the time of calving. Managing all of these things will help to ensure your cows have a better start and make the most out of their lactations. ... Read More...

Pregnancy "Hard Count" Thumb Rule

Mark E. Carson BSc. (Agr). MSc., Gencor Herd Reproduction Analyst Here is some really simple math that can be useful in the barn for assessing herd performance. A good thumb rule is 10% of your herd should be calving out each month. That means (at minimum) 10% of your herd needs to be getting pregnant each month. A "hard count" is simply setting a targeted number of pregnancies. The math is really quick and easy to do. If you are milking 30 cows you should be targeting a minimum of 3 to 4 pregnancies per month. If you are milking 300 cows, the goal should be 30 to 40 pregnancies per month. If you are a herd growing in size, you will need to set a slightly higher goal. Keeping this flow of pregnancies rolling through your herd will help keep your milk production more consistent by ensuring a steady continuation of fresh cows entering your herd. During veterinary herd-health visits, check to see if your herd is reaching its goal of at least 10% of cows getting pregnant per month. If less then 10% of your cows are getting pregnant per month, it would be worth investigating your herd's reproductive performance. As always, work with your veterinarian, nutritionist, Semex representative and other trusted advisors to make sure your herd is reaching its reproductive potential. ... Read More...

Semex Sires Valuable Worldwide In Sales Arena

The value of a cow, heifer or calf can be measured in multiple ways. Many breeders utilize tools designed to measure genetic value and profit potential including TPI, LPI, Net Merit or even the individual traits they're focusing their breeding program on to determine value. Others simply look at what it would cost to replace a cow that has left the herd. In 2007, University of Wisconsin Extension (UWEX) Agents collected data from 49 dairy farms, custom calf and heifer growers from across Wisconsin. This study estimates, under given assumptions including calf value and labor costs, that the average total cost of raising a heifer from birth to freshening ranged from $1595 to $2935, or an average of $2149 (including a given value of $500 for the calf she is carrying). Therefore, a replacement will cost approximately $2100. Many dairymen rely on additional income from selling their excess heifers and cows, allowing the free market to determine the value of their stock, while some seek elite genetics to develop marketable seed stock sold at a premium. 2008 was undoubtedly a phenomenal sale year, supported by high milk prices and an enthusiastic following who marveled each time another record was shattered. Semex sired daughters led the pack, reaching new heights and topping sales in multiple countries including Canada, France, Switzerland, the United Kingdom and the USA. Semex daughters are always the favorites at these sales, with code 200HO having topped many high profile and local sales from coast to coast and around the world. "Semex daughters always stand out in the sale ring," says Julien Chabot, Semex Sire Analyst. "In the sale ring the solid, square animals always sell the best. It doesn't matter whether it's for replacement cattle or for more elite and show cattle. Dairies want to milk cows that look correct and sound. Semex sires are known for ... Read More...

Five Benefits of Excellent Reproduction

Mark E. Carson BSc. (Agr). MSc., Gencor Herd Reproduction Analyst

Achieving excellent reproductive performance is hard work. Here is a quick reminder about the benefits of working hard and delivering excellent reproductive performance in your herd.

1) Higher reproductive performance equals more milk. The average cow in your herd will spend a great portion of lactation near peak performance. Remember, every day open past 100 days in milk cost you approximately $4.50 US per day per cow.

2) Reduce reproductive culls of profitable cows. With more pregnancies occurring, you will have less forced culls due to reproductive failure, giving your herd more culling options. More culling options provides you the opportunity to cull less profitable cows, such as ones with low milk production.

3) Increase the number calves being born each year. With an increase in the number of pregnancies, your herd will have more heifers. These extra heifers can replace less profitable cows, be sold for more revenue or expand your herd from within.

4) More calves being born equals faster genetic improvement. Top daughters will enter your herd sooner, giving your herd a genetic edge.

5) Decrease transition cow problems. Cows that have long lactations and dry periods are at higher risk of developing health problems during their next transition period. Strong reproductive performances can reduce the number of cows that have extended lactations, providing you with less future transition problems.
