It's All In the Genes: Designing and Administering a Brief Survey to Local Dairymen In Order to Gauge their Interest In Genomics

One of the newest technologies available for agricultural use is the sequencing of the bovine genome and the identification of specific genes that would ensure favorable physical traits in the herd. An easy way for this technology to be utilized is in the milking herds of dairies, the herd has already been bred for specific traits and any change due to a genomic influence would be easily seen. Dairy cattle are commonly bred through artificial insemination, and this would be a perfect place for the genomic programs to prove themselves. In order to determine the attitudes of local dairymen toward genomics, I designed and administered a survey to gauge their opinions. The survey was given to a meeting of the United Dairymen of Arizona at their Tempe offices. The survey covered the current breeding methods used by the dairies, the desired attributes in a milking herd and a breeding program, and a place for the dairymen to give their own opinions on genomics. The results indicated that the dairymen are interested of using genomics, but they are unsure of the cost. Dairymen are often looking for new methods to increase their milk production and herd value, but are reluctant to pay a high amount. One recommendation is for these dairymen to utilize bulls that have had their genome analyzed when they are breeding their cows. This would allow the dairymen to see the effects and benefits of genomics on their herd without the dairymen having to front the large start up cost for their own genomic program.

Prevention of Type 1 Diabetes: Review and Recommendations for Icelandic Dairy

The aim of this paper is to investigate the B-casein fractions in Scandinavian and Icelandic milk for evidence to either support or refute the claim that the A1 variant of B-casein is diabetogenic in adolescent populations. Based on the theory that differences in milk protein composition explain a lower incidence of Type 1 Diabetes (T1D) in Iceland when compared to surrounding Nordic countries, an informative poster was created so that a more educated decision can be made by those wishing to take preventative measures against the incidence of the disease. This paper includes a basic background behind the epidemiology of T1D and the Nordic Nutrition Recommendations. Next, comparison between milk protein composition and consumption in Iceland against the other Nordic countries is performed through an in-depth literature review. The review was conducted using PubMed databases until December of 2018. Key findings of this investigation raise concerns regarding the decision between optimizing milk producing rates or breeding for milk devoid of diabetogenic proteins. The current literature on the impact of cattle genetics on the protein composition of milk sheds light on the safety of Icelandic dairy and the resulting health of their population. Icelandic dairy has been evidenced to contain lower levels of A1 b-casein and is considered less diabetogenic. For these reasons, this author would recommend the consumption of Icelandic dairy products over those from other regions.
