Essential Nutritional Aspects

Maintaining optimal livestock health support requires a comprehensive understanding of the nutritional needs of your animals. This includes understanding the specific nutritional requirements of various animals such as cows, calves, and bulls, as well as the importance of water intake.

Cow, Calf, and Bull Nutrition

Proper nutrition is integral to the health of cattle at various life stages. For instance, cattle require constant 24-hour access to roughage, primarily hay, grass, or silage, to keep their digestive systems active and healthy. The amount of feed cattle consume daily varies based on the quality of the feed, with adult cattle on low-quality feed consuming between 1.6% and 1.8% of their total body weight and lactating cows consuming around 2.0% of their body weight per day.

Deficiencies and malnutrition severely impact animals’ growth, development, and production, and in some extreme cases, can lead to irreversible health conditions, disorders, or fatalities (ProviCo Rural). Enriching livestock feeds with high-value supplements such as B12 supplements and salt-based additives containing various micro and macro minerals can enhance the nutritional content.

Proper nutrition significantly influences reproductive performance in animals, impacting fertility in cows and the health and viability of their offspring. Deficiencies in certain minerals such as calcium, zinc, magnesium, selenium, and manganese can lead to poor foetal development, stunted growth, and high calf mortality rates in severe cases (ProviCo Rural).

Water Requirements

Water is a significant component of a livestock's diet and plays a crucial role in their overall health and productivity. Daily water requirements for cattle vary depending on age, environmental conditions, and seasonal weather. For instance, lactating cows need to consume at least three times the water in relation to the milk they produce in addition to their usual intake. Cattle can drink between three and 30 gallons of water per day, and if they are not drinking water, it could be due to unclean water sources or unfamiliar water tastes.

Clean, fresh, cool water is essential for livestock health and production performance. It is therefore advised to keep water troughs and tanks clean using fish or chlorine tablets and a scrub brush, and to ensure animals have easy access to clean, fresh water if they are drinking from a creek bed. Additionally, using deicers in winter is recommended if water freezing is an issue in the area (OSU Extension Service).

By understanding these essential nutritional aspects, farmers can ensure their livestock remains healthy and productive, thereby contributing to the overall success and sustainability of their farming operations.
