Keeping cattle healthy is a top priority for livestock owners. As a veterinary professional specializing in herd health, I am often asked about the fundamentals of cattle wellness - from providing proper nutrition to utilizing vaccinations and maintaining disease prevention protocols. In this comprehensive guide, we will delve into the key aspects of livestock health management, equipping cattle owners with the knowledge and tools for building a thriving herd.

Fundamentals of Cattle Health

When managing herd health, the fundamentals include good nutrition, vaccinations, sanitation, housing, and disease prevention and treatment. By proactively supporting wellness in these core areas, cattle owners can optimize growth, productivity and longevity within their herd.

Nutrition - The Fuel for Growth 🥕

Nutrition is the foundation of livestock wellness, providing the nutrients cattle need for bone, tissue, and muscle development. As ruminants, cattle require fibrous roughage and high quality forage. Here we will explore key nutritional considerations when feeding beef or dairy cattle.

Key Nutrients in Cattle Diets

Cattle diets should include proper levels of:

·         Energy: Metabolizable energy from carbohydrates and fats. This supports growth and lactation.

·         Protein: Especially rumen degradable protein to enable gut function and growth.

·         Vitamins & Minerals: Like calcium, phosphorus, magnesium, potassium. These support enzymatic processes, bone strength, immunity, and more.

Alongside sufficient nutrition, always provide cattle with constant access to clean, fresh water. This supports digestion, nutrient absorption, and overall systemic functioning.

Beef Cattle Nutrition

For beef cattle like cows, steers, and bulls, nutrition programs should focus on:

·         Grass & Hay: 2-3% of body weight in dry matter per day. Provide high-quality grass and hay.

·         Grains: Supplemental grains can include corn, barley, oats. This boosts energy.

·         Vitamin & Minerals: Supplements to balance grass-based diets.

Monitor body condition scoring to assess if adjustments in feed quantity or quality are needed. Refer to the body condition scoring guide from BDVets for assessments.

Beef cattle thrive on fibrous roughage from grass and hay feeding programs

Dairy Cattle Nutrition 🥛

For lactating dairy cows producing milk, nutritional needs differ. Recommended feeding programs include:

·         Hay: At least 1% of body weight per day, provide quality hay.

·         Silage: Fermented, high-moisture fodder. An excellent source of nutrients.

·         Grains: 1 lb of grain for every 3-4 lbs of milk production. Boosts energy.

·         Protein: 14-18% crude protein. Supports milk supply.

·         Vitamin & Mineral Mix: Formulated to support lactation demands.

Monitor milk production, body conditioning, and signs of malnutrition or illness. Adjust diets to optimize nutrition for milk supply and cattle health.

Quality nutrition supports healthy dairy cows and milk production

Now that we have covered fundamental cattle nutrition, let us explore the key role of vaccinations in herd health management.

Vaccinations for Disease Prevention 💉

Vaccinating beef and dairy cattle is crucial for preventing illness and death losses. By administering vaccines, cattle develop antibodies and immunities against dangerous infectious diseases.

Types of Vaccines

The main categories of cattle vaccines include:

·         Killed vaccines: Contain inactivated disease antigens. Stimulate antibody production.

·         Modified live vaccines: Utilize attenuated pathogens. Induce antibody/cell-mediated immunity.

·         Subunit vaccines: Use specific antigenic proteins from pathogens. Also spark antibody production.

Killed vaccines and modified live products can be used individually or combined in vaccine protocols for broad protection against respiratory, enteric, reproductive and systemic cattle diseases.

Commonly Used Cattle Vaccines

Some of the most common vaccines used in herd health programs include:

Respiratory Disease Vaccines

·         IBR (Infectious bovine rhinotracheitis)

·         PI3 (Parainfluenza type 3)

·         BRSV (Bovine respiratory syncytial virus)

·         Mannheimia (Pasteurella)

Reproductive Vaccines

·         Leptospirosis

·         Campylobacter

·         Vibriosis

Clostridia Vaccines

·         Blackleg

·         Enterotoxemia

·         Malignant edema

·         Redwater disease

Pinkeye Vaccines

·         Moraxella bovis

Scours Vaccines

·         Rota-Corona

·         E. coli

Other Vaccines

·        Foot and Mouth Disease

·        Black Quarter Disease

·        Hemorrhagic Septicemia

·        Anthrax

·        Lumpy Skin Disease

By staying current on vaccinations, cattle develop robust immune protection against these dangerous pathogens.

Vaccination is a core component of preventing infectious disease in cattle herds

Vaccination Programs

When designing a vaccination plan, cattle owners and veterinarians consider:

·         Age: Calves vs adult cattle require different vaccine types and timing.

·         Production Type: Dairy vs beef cattle have some varying vaccine needs.

·         Geography: Regional diseases may necessitate location-specific protocols.

Annual veterinary consultations ensure vaccination plans are updated per emerging diseases and herd needs. We also run diagnostics to confirm vaccine efficacy through antibody titer testing.

Refer to sample cattle vaccination schedules from BDVets as a starting point when developing your herd’s protection plan. Reach out to your veterinarian with any vaccine questions.

Proper nutrition and vaccination protocols form the foundation of robust cattle health. Next, we explore the pivotal role of biosecurity, sanitation and housing in keeping cattle clean and comfortable - critical factors for wellness and welfare.
