It is imperative that dairy producers optimize growth in order to prepare their animals for productive purposes as soon as possible. More produce in terms of offspring and milk could be obtained from such fast-growing animals. Thus, bypassing technology to improve protein utilization seems like a rational way out for the purposes above. Among all methods, formaldehyde (HCHO) treatment of cake is the most common for nutrient protection of dietary protein. Bypass protein technology is an efficient and comparatively cheaper method for protecting highly degradable protein sources in the rumen. It involves feed management through passive rumen manipulation with an aim of reducing the ruminal degradation of protein. This will allow this nutrient to get digested and absorbed from the lower digestive tract leading to the improved growth performance of dairy buffalo heifers.
