Nutritional Evaluation and Economic Feasibility of Feeding Urea-Molasses Treated Bamboo (Melocanna baccifera) Leaves to Stall-Fed Crossbred Goats in Mizoram
This study demonstrates that replacing conventional roughage with 100% urea-molasses treated bamboo leaves in the diet of growing crossbred goats significantly enhances nutrient intake, digestibility, growth performance, and economic efficiency without compromising animal health.

In the rugged hills of northeastern India, where the landscape is dominated by dense forests of a specific type of bamboo, a quiet challenge faces the farmers who raise goats. These animals are a lifeline for many rural families, providing meat and a source of income, yet they often struggle to find enough high-quality food, especially during the dry seasons when traditional grasses disappear. Farmers have long known that bamboo leaves are abundant and available year-round, but the leaves are tough and fibrous, making them difficult for goats to digest and often unappealing to eat. To solve this, scientists have explored a method called urea-molasses treatment. This process involves soaking the chopped leaves in a mixture of urea, which is a source of nitrogen, and molasses, a sweet syrup. The goal is to soften the tough fibers and boost the protein content, effectively turning a low-quality, hard-to-eat plant into a nutritious meal that ruminant animals can thrive on.
A team of researchers at the Central Agriculture University in Mizoram set out to test whether this treated bamboo could serve as a complete replacement for the usual grass in the diet of growing goats. They focused on a specific species, Melocanna baccifera, which covers a vast portion of the state's forest area. The scientists gathered fresh leaves, chopped them into small pieces, and mixed them with a solution containing four percent urea and a generous amount of molasses. After letting this mixture sit under a tarp for twenty-eight days to allow the chemical changes to take place, they prepared three different feeding groups. One group of goats received a standard diet of grass and concentrate feed. A second group had half of their grass replaced with the treated bamboo, and a third group had their entire grass portion swapped out for the treated bamboo, receiving no conventional grass at all. The study ran for nearly two months, during which the researchers carefully tracked how much the animals ate, how much they grew, and how well their bodies processed the food.
The results showed a clear and positive trend as the amount of treated bamboo in the diet increased. The goats that ate the diet with the highest proportion of treated bamboo not only consumed more food overall but also grew faster than those on the standard grass diet. The animals in the group that received the full replacement of grass with treated bamboo gained the most weight, averaging over eighty grams per day, compared to just thirty-six grams for the goats eating the standard diet. This improvement was not just about eating more; the animals' bodies were also better at breaking down the food. The researchers found that the goats fed the treated bamboo digested the nutrients in their food more efficiently, absorbing more of the protein and energy available in the leaves. This suggests that the treatment successfully softened the tough fibers and made the nutrients accessible to the animals' digestive systems.
Beyond growth and digestion, the study looked at the health of the animals to ensure the new diet was safe. Blood tests taken at the beginning, middle, and end of the experiment showed that all the goats remained healthy, with their blood chemistry staying within normal, healthy ranges regardless of what they ate. This confirmed that the treated bamboo did not cause any hidden harm or stress to the animals. The researchers also calculated the economics of the feeding plans. While the treated bamboo diet cost more to prepare per kilogram of feed than the standard grass, the rapid growth of the animals meant that the cost to produce each kilogram of body weight was actually lower for the treated bamboo groups. In fact, the group that ate only the treated bamboo was the most cost-effective, requiring the least amount of money to achieve a kilogram of weight gain.
The study concludes that this treated bamboo is a viable and even superior alternative to traditional grass for raising goats in this region. By replacing the conventional roughage entirely with the urea-molasses treated bamboo, farmers can improve the growth rate of their animals and reduce the overall cost of production, all without compromising the health of the herd. This finding offers a practical solution for a region rich in bamboo but often short on other fodder, turning an abundant local resource into a reliable engine for livestock production. The research demonstrates that with a simple chemical treatment, a tough, fibrous leaf can be transformed into a high-quality feed that supports robust growth and economic efficiency for resource-limited farmers.
