The experiment was conducted on twelve male local goats, aged 1-1.5 years with a body weight of 12.839 ± 0.496kg. The ration was prepared with a 60:40 ratio of forage to concentrate. The basal feed was made of Gamal leaves, while the concentrate consisted of soybean meal, ground corn, rice bran, coconut meal, and ground corn gelatinization product with urea. The experimental method used in this study was a 4x3 completely randomized design (CRD) with four treatments. The treatments applied were T0 (control), T1, T2, and T3. T0 was the basal feed + concentrate without ground corn gelatinization product with urea, while T1, T2, and T3 were the basal feed + concentrate with 1.5%, 2.5%, and 3.75% ground corn gelatinization product with urea, respectively. The data collected were statistically analyzed using analysis of variance and Duncan's multiple range test. The results showed that the treatment had a significant effect (P <0.05) on total dry matter consumption, ration utilization efficiency, and economic value of rations. In conclusion, the study found that the use of ground corn gelatinization products with urea is a viable option for enhancing the quality of goat rations.

Introduction The use of protein source feed as a supplement to the ration of ruminants such as goats is economically very expensive and inefficient in terms of the importance of its utilization. Feed resources for livestock in the tropics generally come from natural pastures and are available from low-quality grasses that are in limited supply during the dry season [1], while feeding grass forages, leaves, and concentrates with low nutritional value cannot always meet the nutritional needs of ruminants. According to Beigh et al. [2], effective utilization of available feed resources is key to economic livestock rearing, and with approximately 70% of the cost input for feed in the production system, optimal metabolism, and digestion are important for an efficient and economical production system [3]. Therefore, improving feed-to-milk or meat conversion efficiency can significantly impact the profitability of ruminant rearing [4]. However, while improving production efficiency remains a key objective of all livestock enterprises, feed costs and animal performance need to be assessed independently of market prices to provide benefits not only for producers but also for animal welfare and the environment. Urea is known to be utilized as a source of nitrogen supplement ruminant rations. Urea is a simple compound that contains 46.7 percent nitrogen while protein source feed generally contains 16 percent protein. Therefore, according to Panday [5], since protein from feed crops such as soybean meal is expensive, it is economically better to use urea as a protein supplement in ruminant diets. Urea is known to be very quickly broken down/hydrolyzed in the rumen into
