Animal Industry Report

Objective evaluation of feet and leg joint conformation is a needed step to improve the repeatability of selection of animals based on proper structure. Objective measurements were taken at the time of selection and during second gestation. Phenotypic and genetic parameter estimates were obtained to better understand the relationship between the measures obtained from objective evaluation. Heritability estimates were low to moderate for all traits measured. Genetic correlations between and within traits at the same time point and between time points were all either small or not different than zero. Low to moderate heritability estimates indicate the ability for these ...

Animal Industry Report

Selection for decreased RFI is controversial from a welfare standpoint, given that the genetic variation in RFI reflects the genetic variation in activity and response to stress. The objective of this experiment was to examine the behavioral metric correlations and growth performance of barrows divergently selected for residual feed intake (RFI) during a novel object test. Forty low-(LRFI, more feed efficient) and 40 high-RFI (HRFI, less feed efficient) barrows from the 8th generation Yorkshire selection lines were randomly selected. Barrows were evaluated in a Novel Object Test for zone crossing, zone 1 (defined as the mouth, nose, and/or ...

Selection For Increased Natural Antibody Levels To Improve Disease Resilience In Pigs, Laura E. Tibbs, Carolyn Ashley, Austin Putz, Kyu-Sang Lim, Michael K. Dyck, Frederic Fontin, Graham S. Plastow, Jack Dekkers, John C. S. Harding

Animal Industry Report

Breeding animals are typically raised under high health conditions in nucleus herds, but their offspring are often exposed to multiple disease challenges in commercial production facilities. Because breeding animals are not exposed to many common swine pathogens, it is difficult to select for resilience to disease. A possible solution is selecting for levels of natural antibodies (NAb), which can be measured in a high health environment and in this study are shown to correlate with disease resilience and to be heritable (h2 = 0.11 to 0.39). Therefore, breeding for increased NAb levels in clean conditions could be a valuable ...

Climatic Factors Affecting Quantity And Quality Grade Of In Vivo Produced Bovine Embryos, Josue Chinchilla-Vargas, Marianna M. Jahnke, Tyler M. Dohlman, Patrick Gunn, Max F. Rothschild Jan 2018

Climatic Factors Affecting Quantity And Quality Grade Of In Vivo Produced Bovine Embryos, Josue Chinchilla-Vargas, Marianna M. Jahnke, Tyler M. Dohlman, Patrick Gunn, Max F. Rothschild

Animal Industry Report

The present study investigated the effects of climatic variables on the quality grade and quantity of in vivo produced bovine embryos. High temperature during the early embryonic development stage, one day after AI to flush, tended (P < 0.10) to decrease the quality of embryos recovered. High Temperature-Humidity Index during the early antral follicular stage, 40 to 45 days prior to ovulation, tended to improve the total number of freezable and transferrable embryos recovered per flush (P < 0.10). Increased wind speed at the early antral follicular phase was associated with a significant increase of the percentage of quality grade 1 embryos recovered (P < 0.05). This implies that wind has a significant effect in the quality grade and quantity of in vivo produced bovine embryos that is rarely taken into consideration.

Effects Of An Oral Supplement Containing Calcium And Live Yeast On Circulating Calcium And Production Parameters Following I.V. Lipopolysaccharide Infusion In Dairy Cows, Mohmmad Al-Qaisi, Sara Kvidera, Erin Horst, Carrie Shouse, Johana Mayorga, Nathan Upah, Denny Mackilligan, Leo Timms, Lance Baumgard

Animal Industry Report

Administrating lipopolysaccharide (LPS) decreases circulating calcium (Ca) and markedly reduces both feed intake and milk yield in lactating cows. Calcium is involved in immune system activation and live yeast can increase feed intake. Whether supplemental live yeast and Ca benefits immune-challenged cows remains unclear. Therefore, study objectives were to evaluate if providing an oral supplement containing soluble Ca, live yeast and other micronutrients would ameliorate LPS-induced hypocalcemia and production parameters in lactating dairy cows. Providing an oral supplement containing Ca and live yeast prior to and following LPS administration markedly ameliorated the LPS-induced hypocalcemia and improved DMI and milk yield ...

Effects Of Age Of Dairy Calves First Offered Free Drinking Water On Feed Intake, Growth, And Health, Janaka Wickramasinghe, Ranga Appuhamy

Animal Industry Report

Offering adequate amount of clean drinking water to dairy calves has become recently a significant concern in the dairy industry. This also brought attention to the fact that many dairy farmers wait for a couple of weeks to offer drinking water to newly borne calves even though offering water from birth is the recommendation. Neonate calves could consume considerable amount of water via whole milk or milk replacer but it’s not clear that amount alone would fulfill the water requirements to support growth and development. The present study was conducted to examine the effects of receiving drinking water from ...


Secure Milk And Secure Beef Supply Plans- Role Of The Veterinarian, Molly Lee Jan 2018

Secure Milk And Secure Beef Supply Plans- Role Of The Veterinarian, Molly Lee

Animal Industry Report

Veterinarians have a tremendous responsibility— and opportunity— to help their clients prepare for a potential foot and mouth disease (FMD) outbreak. While eradication of FMD, should it occur in the U.S., is the ultimate goal, the old approach to FMD response— massive depopulation— is no longer workable except in a small outbreak. The size, structure, efficiency and extensive movement in cattle production will likely require alternative response options to manage disease spread, such as vaccination and allowing animals to recover.

Secure Milk Supply (Sms) Plan For Continuity Of Business, Danelle Bickett-Weddle Jan 2018

Secure Milk Supply (Sms) Plan For Continuity Of Business, Danelle Bickett-Weddle

Animal Industry Report

The Secure Milk Supply (SMS) Plan provides a workable continuity of business (COB) plan for dairy premises with no evidence of foot and mouth disease (FMD) infection in a regulatory Control Area to move raw milk to processing that is credible to Responsible Regulatory Officials (local, state, tribal, and federal officials, as appropriate). Officials must balance the risks of allowing movement of raw milk against the risk of not allowing movement and thus the necessity for on farm disposal of raw milk. FMD is a highly contagious foreign animal disease that infects cattle and other cloven-hooved livestock, such as swine ...


The Influence Of Supplemental Zinc And Ractopamine Hydrochloride On Mineral And Nitrogen Retention Of Beef Steers, Remy Carmichael, Olivia Genther-Schroeder, Stephanie Hansen Jan 2018

The Influence Of Supplemental Zinc And Ractopamine Hydrochloride On Mineral And Nitrogen Retention Of Beef Steers, Remy Carmichael, Olivia Genther-Schroeder, Stephanie Hansen

Animal Industry Report

The objective of this study was to ascertain how ractopamine hydrochloride supplementation and Zn supplementation affects N retention and Zn absorption in beef steers. No interaction was detected between ractopamine hydrochloride supplementation and Zn supplementation (MIN x BA strategies). There was no effect of ractopamine hydrochloride inclusion on Zn absorption. However, there was an increase of Zn retention with increasing concentrations of supplemental Zn. Additionally, N retention was increased by supranutritional Zn supplementation and also by ractopamine supplementation. Increased N retention may help explain previously noted improvements in cattle performance when fed ractopamine hydrochloride and supranutritional concentrations of Zn.

Six Year Summary Of Foliar Fungicide Use In Alfalfa Production, Brian Lang, Ken Pecinovsky Jan 2018

Six Year Summary Of Foliar Fungicide Use In Alfalfa Production, Brian Lang, Ken Pecinovsky

Animal Industry Report

The best probability of achieving an economic response to a foliar fungicide application in alfalfa production is to first crop. Other than that, we need to be more selective of our opportunities for an economic return based on scouting, yield potential, environmental conditions and alfalfa forage value. To apply fungicides to alfalfa without consideration for yield potential of individual cuttings or environments favorable to disease development would not follow proper stewardship of pesticide use nor result in maximizing
