Plant-Based Milk Beverages Affect Children’s Height

By Ross Tellam

A recent large-scale scientific study concluded that children drinking plant-based substitutes for cow’s milk were associated with slightly shorter height [1]. The authors speculate the study provides the first indication that the increasingly popular consumption of nondairy milk substitutes may not adequately support the full nutritional requirements of rapidly growing young children. Children’s height is used as an index of health and normal development. • Children consuming noncow’s milk beverages are shorter in height than those consuming cow’s milk. • Some plant-based milk substitutes may not adequately support the full growth and developmental needs of children. •

What Determines Human Height?

Geneticists conclude that human height has a strong genetic component accounting for about 60–80% of the variation in height of a population, i.e. tall parents usually produce tall offspring [2,3]. The remaining 20–40% of the variation in height is due to factors such as nutrition and illness [2–4]. The anthropologist Franz Boas identified the strong influence of environment on human height over one hundred years ago [5]. He noted that children of immigrants to the USA when adults were on average taller than their parents. Boas attributed this observation to better nutrition. Some individuals never reach their full genetic potential for height due to adverse environmental influences such as illness and poor nutrition. Height is, therefore, a sensitive indicator health status. Five Foot Tall and Rising (Johnny Cash)

Livestock Drug Use: New Laws & New Opportunities Dr.MichaelPayne,UCDavis, SchoolofVeterinaryMedicineandDirector,CDQAP Starting January 1 st 2018, a prescription from your herd veterinarian will be required to purchase a “medically important antibiotic”. While most producers are generally aware of these new regulations, there is some information regarding the implications for farm operations that is important to keep in mind. Much of the discussion around antibiotic resistance has centered around preserving antibiotic effectiveness for human use, and while that is critically important, preserving antibiotic effectiveness is just as critical for animal use. The Center for Disease Control (CDC) estimates that more than two million antibiotic-resistant infections occur in people every year, resulting in some 23,000 deaths. The medical community has been tackling the issue with outreach to consumers and doctors like the CDC’s “ Get Smart ” Program. Similarly, in California all hospitals and nursing homes are required to implement “ Antibiotic Stewardship ” programs to promote responsible antibiotic use and limit development of resistance. On the animal side, certainly a significant percentage of antibiotic use occurs in livestock, although recent research suggests that movement of resistant bacteria most commonly occurs from humans to animals rather than in the reverse direction. That said, any antibiotic use, regardless of whether it is in humans, pets or livestock, does tend to promote resistance. California’s new livestock medication laws involve all animal species and seek to leverage the efforts being taken on the human side. The expectation is that expertise provided by the herd veterinarian will help optimize antibiotic use on farms, limiting development of resistance.Because most dairy producers have a herd vet and are using prescription medications under their supervision, the effect on dairy operations should be modest. That said, there are several potential advantages to regular review of the dairy’s treatment program. Using resistance data collected from farm mortalities, a herd veterinarian may be able to identify lower-tier, less expensive antibiotics that are still effective. Re-examination of disease management programs such as those for mastitis, metritis or lameness, offer even greater savings, since it is always cheaper to prevent disease rather than to treat it. Perhaps most importantly, as treatments are reduced, so does the selective pressure on the dairy’s pathogens. Ultimately this should mean that antibiotics used on the farm will remain effective for years to come.

NOVEMBER 2 Ferndale City Hall 834 Main Street *************************** It’s time to winterize! DeanneMeyer,Ph.D.UCCE Livestock WasteManagementSpecialist, DepartmentofAnimal Science,Davis It’s that time of the year again! With less daylight comes the reminder to prepare for winter. Now is the time to think “winter” as you drive around the dairy. Here’s an abbreviated to-do list. A quick review of your Operation and Maintenance Plan will help complete your dairy’s specific preparation list. ✓ Pile, remove and haul or cover solid manure from corrals ✓ Fill low spots in corrals ✓ Check gutters, down spouts, attach flexible hose if needed

Now is the perfect time to schedule a health and treatment program review with your herd veterinarian with an eye towards optimizing treatment programs and reducing medication costs. In the coming months and into the new year, CDQAP will be providing more detailed information on the new livestock medication laws and will focus on cost-saving opportunities. ******************************************************************* ✓ Have winter storm sampling kit available ✓ Input remaining nutrient management data for your summer crop (irrigations and harvest data) ✓ Transition from monthly to weekly documentation that production area is clean and no off-site discharge of manure (solids or liquids) is occurring ✓ Begin keeping records for each field for winter forage nutrient management Here’s hoping our rains come when needed and with just the right amount of water!

Check generators to be sure they are functional

✓

Evaluate pond storage capacity

✓

Remember to take monthly pond photos (in the valley) or annual pond photos (north coast) Continued at right.
