Most MR use edible lard as the fat source, which contains primarily long-chain fatty acids (LCFA). However, 10.8% of FA in Jersey whole milk are medium-chain fatty acids (MCFA). The objective of this study was to determine whether altering the FA profile of MR with coconut oil (CO), which contains a high concentration of MCFA, to more closely match the FA profile typically found in whole milk from Jersey cows, would improve Jersey calf performance. Male (n = 18) and female (n = 32) Jersey calves were assigned at birth to 1 of 4 liquid diets: 1) pasteurized Jersey saleable whole milk (pSWM; 27.9% CP, 33.5% fat); 2) 29.3% CP, 29.1% fat MR containing 100% of fat as edible lard (100:00); 3) 28.2% CP, 28.0% fat MR containing 20% of fat as CO (80:20); 4) and 28.2% CP, 28.3% fat MR containing 40% of fat as CO (60:40). Calves were fed their respective liquid diet twice daily during wk 1 through 7 and once daily until weaning (approximately wk 8). Calves had ad libitum access to grain and water. Calves were monitored 1 wk post-weaning. Calves were weighed at birth and once a week thereafter. Hip height (HH) and wither height (WH) were taken at birth, and 4, 7, and 9 wk. Grain refusals and fecal and respiratory scores were recorded daily. Average daily gain and BW did not differ by treatment. Calves fed pSWM tended (P = 0.10) to have greater HH than calves fed 80:20 (80.5 vs. 79.7 cm). Coconut oil tended to have a quadratic effect on HH, with calves fed 100:00, 80:20, and 60:40 at 79.2, 79.7, and 78.5 cm, respectively. There was no difference in WH between pSWM and 80:20. Coconut oil had a quadratic effect on WH, with calves fed 100:00, 80:20, and 60:40 at 76.6, 77.5, and 76.5 cm, respectively. Change in HH from birth to 9 wk tended to be greater for calves fed pSWM than calves fed 80:20 (0.218 vs. 0.194 cm/d). Calves fed pSWM had a higher milk DMI intake than calves fed 80:20 (0.523 vs. 0.498 kg/d). There was no effect of CO on milk DMI. Grain DMI and total DMI did not differ among treatments. Calves fed pSWM had an increase in days with a fecal score > 2 compared to calves fed 80:20 (4.24 vs. 2.00 d). Coconut oil had a quadratic effect on fecal score, with calves fed 100:00, 80:20, and 60:40 scouring 4.00, 2.00, and 3.63 d, respectively. Respiratory score did not differ among treatments. In conclusion, DMI and ADG were similar among treatments. However, differences among treatments in skeletal growth and fecal scores are indicative of some possible benefits in MCFA on calf health and performance. Additional data on adipose tissue and liver biopsies may provide further evidence of such benefits. 2011-12-19 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1322669397 http://rave.ohiolink.edu/etdc/view?acc_num=osu1322669397 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
