It is well known that daughters from artificial insemination (A.I.) sires produce more milk than those bred by natural service. Incorrect A.I. techniques can lower the overall success rate of your breeding program. At one time, most producers have learned correct techniques in semen handling and insemination procedures, but unfortunately, many have developed some bad habits. Reviewing proper procedures should help eliminate many of these mistakes.

The new discovery of a lethal gene may explain why pregnancy rates in dairy cattle have dropped sharply in recent years, a University of Wisconsin – Madison researcher says.

PACE success reaches new levels with November sire summary Accelerated Genetics continues to maintain an active lineup full of leading genetic sires in all breeds that graduate from the PACE young sire program. Topping Accelerated Genetics lineup for both Net Merit and TPI™ is PACE graduate 014HO04099 Billion. Eighteen daughters were added to his type proof, bringing this high-ranking sire to the elite +2.00 PTAT level. Billion also increased significantly on his Udder Composite (UDC) at +1.63, and his Foot and Leg Composite (FLC) at +2.44.

In recent years, several estimates of embryonic mortality in cattle have been made. Embryonic mortality is generally defined as loss of the conceptus which occurs during the first 42 days of pregnancy, which is the period from conception to completion of differentiation when organ systems develop.

In the years since the formation of the Newaygo Dairy Testing Association, the first Cow Testing Association (CTA) that started in America in the fall of 1905, production records have become the foundation for herd improvement. This was noted in the early years by the fact that the name was changed nationally in 1927 to the Dairy Herd Improvement Association or DHIA.

A dairy herd’s reproductive program is one area that often leads to large profit losses. This [article] takes a look at the economic considerations associated with reproduction.

Call it the high-producer paradox – as dairy cows’ milk production rises, pregnancy rates fall and reproductive difficulties increase. The most profitable, highest producing cows in a dairy herd can become the least profitable because of reproductive problems.

Taurus adds a new Powerhouse Taurus Service, Inc., announces the debut of 76HO0437 Windy Knoll View Powerhouse EX-93. This Outside son of Stardust Peggy x Pala exhibits an impressive type profile without a single negative in his proof. He is +2.54PTAT +2.09 UDC +2.02 F&L. Powerhouse is siring daughters with extreme size and strength with a deep, open rib structure. He also scores 2.93 Strong for fore udder attachment and 2.79 High in rear udder height. A breed leader at +3.5 PL and low SCS (2.90), along with having positive values for milk, fat and protein pounds and percent, Powerhouse is the new bull to consider with +1568 TPI.

Interest in crossbreeding is at perhaps an all-time high among commercial dairy producers internationally. Over the past 50 years, North American Holsteins have steadily increased as a percentage of the national dairy herd in most countries. However, circumstances have changed regarding the historical superiority of pure Holsteins compared to crossbreds.
