Many livestock farmers wonder why skeletal development is emphasized during the calf-raising stage. Isn’t a calf’s skeletal structure predetermined by genetics? While genetics do play a role, the key is to maximize skeletal growth during the calf’s critical growth period by providing adequate and balanced nutrition. This ensures the animal can reach its full potential. Then what is the optimal period for skeletal development in calves, and what nutritional supplements are needed during this phase?
The Optimal Period for Skeletal Development：
The Optimal period for skeletal development in calves begins when they reach around 150 kg and continues until they reach 400 kg. This stage marks the rapid growth of the skeletal system. A well-developed skeletal structure during this time provides the foundation for later stages of fattening and weight gain.
Some farmers make the mistake of feeding only maize flour and soybean meal during this stage. While these provide energy, an energy-heavy diet can result in muscle and fat growth without adequate skeletal development. This can lead to a plateau in growth, with fattening cattle stalling at around 550 kg.
Nutritional Needs for Skeletal Development：
To optimize skeletal growth, calves need a diet rich in high protein, high calcium, high phosphorus, high vitamin, etc. High protein supports bone growth. To ensure rapid skeletal development, providing sufficient protein or amino acids is essential. it’s also important to maintain a balanced ratio of concentrate in the diet, the proportion should not be too high and is recommended to be equal to 1% of calf’s body weight per day. At the same time, roughage (like hay) should be available in unlimited amounts, sufficient dry matter intake is also essential for skeletal growth.
Supplementing for Better Digestion and Growth：
To further support growth, consider feeding some rumen-improving additives, which can enhance rumen fermentation and intestinal digestion, and improve overall nutrient absorption, especially for proteins. This not only promotes rapid skeletal development but also prepares the animal for the subsequent fattening phase.
By focusing on proper nutrition and rumen health during this critical growth phase, farmers can set the foundation for optimal weight gain and productivity in beef cattle.
