Abstract

Sixty-two commercial Angus/Brangus based cow-calf pairs were sorted into groups using a 2x2 factorial design. Cows were divided into two groups, immature cows (≤3 years old; n=19) and mature cows (≥4 years old; n=43) and further separated into two groups: treatment (creep-fed) calf group (n= 29) and control (non-creep-fed) calf group (n=33). Starting at Day 1, creep-fed calves were fed 1% of average calf body weight once daily, increasing by 0.5% every two weeks for six weeks. Every two weeks calves and cows were weighed and body condition scores (BCS) on cows were recorded, and treatment groups were rotated between pastures. On Day 43, final weights and cow BCS were recorded, and calves were weaned. Calves were comingled and fed for an additional 50 days and then sold. Overall, creep feeding calves showed additional benefits for calf average daily gain but was not the only factor to improve this gain. Calf Sex, Cow Age, and Calf Age Group in combination with creep feed and other variables also aided in increased calf ADG. Regarding cow performance, immature cows with creep fed calves lost less weight and showed a greater average body condition score. While calves with a creep fed background were more profitable than non-creep fed calves, it was not the only factor that added value to the calves, as Calf Sex and Cow Age also had an impact on profitability of the cattle.
