The utilization of feed is depended on quality, quantity, type, breed, and rate of passage of feed. This study aimed to evaluate the performance, feeding behavior, and nutrient utilization of growing Etawah crossbred and Senduro goats fed different forms of starter concentrate of creep feed. Materials and methods: Twelve local growing goats were used in this study, consist of six Etawah crossbred and six Senduro goats with average body weight 20 ± 1.57 kg from both sex, fed different forms of creep feed for three month. This study was designed by factorial randomized completely block design 2x2. The first factor was type of creep feed form (mash and pellet), and the second factor was the type of goat breeds (Etawah crossbred and Senduro). The complete ration consisted of 70% creep feed containing black soldier fly (BSF) meal and BSF oil plus 30% elephant grass. The variables observed were feeding behavior nutrient consumption, digestibility, blood metabolites, and performance. Results: The results showed that there was no interaction between the creep feed forms and the goat breeds in all variables. The form of creep feed had a significant effect on prehension and mastication and the pellet form had higher prehension and mastication compare to mash from but it had no significant effect on nutrient consumption and digestibility. Performance and blood metabolites were same in all treatments, except for the feed efficiency of Senduro goats had higher than Etawah crossbred goats. Conclusion: In conclusion, giving creep feed containing BSF larvae meal and oil in starter concentrate as pellet forms resulted a lower prehension and higher mastication, but has higher prehension and lower mastication for mash type. The performance and blood metabolites were are not different in all treatment groups. 09 04 2024 24 29 https://creativecommons.org/licenses/by/4.0 10.58803/jvpp.v3i3.43 https://jvpp.rovedar.com/index.php/JVPP/article/view/43 https://jvpp.rovedar.com/index.php/JVPP/article/download/43/66 https://jvpp.rovedar.com/index.php/JVPP/article/download/43/66 10.5713/ab.21.0460 10.5398/tasj.2019.42.2.145 McDonald P, Edward RA, Greenhalgh JFD, and Morgan C.
