Understanding Sire Proofs – an important tool for genetic selection

In the US all bulls are progeny tested and records are collated. They are peer reviewed and in addition any improvements are highlighted. The testing results are available every 4 months and farmers wait for these proofs. But it is important to understand the proofs (how to read the sire proofs) and decide of which animal is suitable for breeding at the farm and what kid of improvement can be expected


World Wide Sires E News – Jan 2016 provides just that. Use the link below on how to read the US Sire Proofs.

Its all about Rumen Development of Calves to get them growing faster

Calves need a good start and it is important and producers need to give that head start to the calves, if they want these animals to perform later in life. Must get Colustrum at least 2 – 3 liters in first 1 hr of life, start on grain based calf starter within 3-4 days, Milk to continue for 60 days or mik replacer if possible.

WWS – News for July 2015 is focussed on calf and its rumen development. Click below for details

Manage summer stress to get more cows pregnant; Cool cows conceive better

Summer is a difficult time for a cow-herd. As temperatures rise, cows eat, ruminate and lie down less, which has a negative effect on their comfort, production and reproduction. Here are a few ways to manage heat stress in your herd:

Enough water to the animals

  1. Keep animals hydrated – Cows will drink 30 percent more water during times of heat stress. Avoid dehydration by providing easy access to cool, clean drinking water. Provide at least one, 1 meter water trough for every 15 to 20 cows. Make water available to cows when exiting the parlour, in addition to troughs in the barn and/or pasture.

  1. Provide shade – Shade is an inexpensive way to give cows relief from the sun. Make sure cows have access to covered areas. You can also use shade cloth to block the sun from exposed areas.
  1. Provide fans/soakers – When soakers/misters are used with fans, the water on the cow’s skin and the air movement from the fans cools the cow. Fans and soakers placed at the feed bunk encourage eating. They are also useful in the holding pen; cows create heat as they crowd together waiting to be milked.
  1. No OvercrowdingAvoid overcrowding – Like in the holding pen, body heat from the cows can increase heat stress. Limit overcrowding to increase air flow. Housing should not exceed 120% capacity, meaning if you have 120 cows in a pen, there should be at least 100 beds. (Photo Courtesy: Dairy Business)
  1. Focus on nutrition – Maintain feed intake by providing a balanced ration with increased energy density and high quality forages, and by feeding during the cooler times of day.

It can be a challenge to get cows pregnant during times of heat stress because it is harder to detect heats and cows are less likely to conceive. While the previously mentioned heat abatement strategies can be used to improve reproduction for heat stressed cows, you can also better your chances of getting cows pregnant by selecting bulls with higher conception rates and daughter pregnancy rates.

Selecting bulls with a high Sire Conception Rate (SCR), is a great strategy to overcome low fertility in heat stressed cows.

What is SCR?

SCR measures the fertility of the bull and his ability to create pregnancies. A negative SCR means a bull is below average at creating pregnancies, while an SCR of 1.0 indicates a bull is above breed average and 1% better at creating pregnancies. For example, in a herd with a 35% conception rate using average SCR bulls, a +2.0 SCR bull would be expected to have a conception rate of 37%.

There are several of WWS bulls, with higher SCR that can help you combat reproductive issues in the summer.

World Wide Sires Delivers Industry Leading Genetics

World Wide Sires (WWS) bulls dominate the industry with outstanding fertility, creating high producing daughters with healthy and balanced udders, strong feet and legs, and excellent TPI. WWS delivers a diverse line up of bulls and offers elite genetics for every management system.

High fertility is a top priority for any well-managed herd. WWS bulls are ahead of the competition for semen fertility as measured by SCR, or Sire Conception Rate. Sire Conception Rate is the standard for comparing bull fertility, and WWS is home to more high SCR bulls than any other AI company.

 Based on the April 2015 genetic evaluations, WWS has 58 proven bulls at or above +1.5 SCR.

WWS delivers PregnanciesWWS is also home to 30 proven bulls above +2.5 SCR, three times the number of theSCR Averagesnearest competitor. Only 23 proven bulls in the breed rank above +3.0 SCR, and WWS leads the way as your source for 14 of these elite fertility sires. The WWS lineup has an average SCR of +1.46, which is well over the industry average of +0.55 SCR and higher than any individual competitor.

Daughter of WrightWhen considering the Fertility Index (64% daughter pregnancy rate (DPR); 18% heifer conception rate (HCR); 18% cow conception rate (CCR)), bulls like 7HO11123 WRIGHT, with a fertility Index of 4.9 (Daughter photo on the leftand 7HO11150 ZIGGY with a fertility index of +4.6, create fertile daughters that breed back quickly.

Daughter of Supersire

WWS bulls also transmit high production. 15 of the Top 50 PTA Milk sires call WWS home, while the next competitor has 9 bulls on the list. 7HO11351 SUPERSIRE, woth a PTAM of +2190 (Daughter photo on the left) the number one TPI sire in the world at +2613 TPI, also ranks second in the breed for production and is an extreme transmitter for milk (PTAM of +2190)

 Daughter of BrokawOn the Top 50 Udder Composite list, 16 are WWS bulls and the

next competitor has 9 on the list. Sires like 7HO11118 BROKAW , a UDC of +2.91 (Daughter photo on left) and 7HO11477 MCCUTCHEN, a UDC of +2.81. These produce daughters with extremely high, wide rear udders and strongly attached fore udders.

Daughter of Tempo

In regards to udder health, 16 of Top 50 SCS Sires call WWS home, while the next competitor has 8 on the list. WWS is also home to the number one SCS bull in breed, 7HO10624 TEMPO at +2.54 SCS (Daughter photo on the left).

Daughter of Airlift

WWS claims the top 5 spots on the Top 50 Feet and Leg

Composite list and has at total of 18 bulls on the list, with the next competitor at 10. 14HO06809 AIRLIFT, with FLC of +3.74 (Daughter photo on the left), 7HO11314 MOGUL, with FLC of +3.5 , 7HO10506 GW ATWOOD, 7HO11279 MOONBOY and 7HO10999 BRADNICK are FLC breed leaders who sire daughters that walk comfortably with moderate set to the hock and steep foot angle.

Daughter of MoonboyDaughter of MixerWWS also continues to dominate the breed for TPI with 35 of the Top 100 TPI Sires, while the next competitor has 19 on the list. 6 of the top 10 TPI Sires also call WWS home with No.1 7HO11351 SUPERSIRE, No.2 7HO11314 MOGUL, No.5 7HO11279 MOONBOY, TPI of +2396 (Daughter photo of right), No. 6 7HO11313 MIXER, TPI of  +2396 (Daughter photo of the left), No. 7 7HO11477 MCCUTCHEN, and No.9 7HO10721 BOOKEM.
