Abstract:

This study investigated the effects of combining lysolecithin and chromium as dietary supplements on the performance, blood profile, and carcass characteristics of Ongole crossbred bulls. A total of 24 bulls were randomly assigned to four groups under a 120-day feeding regime: control (no lysolecithin or chromium), L20gC5mg (20 g lysolecithin + 5 mg chromium), L30gC5mg (30 g lysolecithin + 5 mg chromium), and L50gC5mg (50 g lysolecithin + 5 mg chromium). Parameters observed included dry matter intake, body weight gain, nutrient digestibility, blood profile, and carcass traits. Bulls fed the L50gC5mg diet exhibited higher average daily gain (ADG) (1.11 vs. 0.56 kg/head/day; p=0.063) and significantly lower feed conversion ratio (FCR) (6.44 vs. 18.7; p=0.043) than controls during the 31-day feeding period. This group also demonstrated the highest neutral detergent fiber (NDF) digestibility (p=0.015). Blood plasma analyses revealed higher lipase concentrations (p<0.001), and carcass analysis indicated more trimmed fat (p=0.045) for bulls receiving L50gC5mg compared to control or L20gC5mg groups. Overall, supplementation with 50 g lysolecithin and 5 mg chromium significantly improved early-stage ADG and FCR, fiber digestibility, and lipid deposition in Ongole crossbred bulls.
