Book Description
The objectives of this research were to 1) evaluate the effects of late gestation supplementation, synchronization and creep feeding on cow and calf production traits 2) evaluate the pooled effects of 5 studies involving late gestation supplementation on cow and calf traits. Experiment 1 was a three year study conducted on 8 pastures at the Gudmundsen Sandhills Laboratory. Cows were assigned to 1 of 4 late-gestation supplementation treatments, postpartum progestin or control, and 1 of 2 creep feed treatments to make up a 4 x 2 x 2 factorial arrangement. Calves were followed through to slaughter. Experiment 2 involved 5 studies all conducted at the UNL Gudmundsen Sandhills Laboratory. Studies were pooled based on similar treatments of late gestation supplementation on dormant upland pasture or meadow and different weaning periods. Cow and calf data was analyzed for various traits. Within Experiment 1 all three levels of supplementation increased cow BW and BCS, while the non-supplemented decreased in both. Supplementation treatments did not affect reproductive efficiency such as calving date, calving rate, weaning rate or pregnancy rate. Synchronization had similar results as there were no effects on reproductive measures or calf BW. Supplementation to cows had no effect on calf production traits through slaughter. Creep feeding calves significantly increased calf BW at weaning, yield grade and 12th rib fat. However on a cost/ benefit analysis creep feeding under these conditions added no value on profitability. Different results were achieved with the larger data set of late gestation supplementation. The pooled analysis demonstrated significant effects from supplementation on cow pregnancy rate, adjusted calf BW at weaning but no effect on carcass characteristics. March systems had a higher average pair feed cost but lower cow replacement cost compared to May. The March calving system had higher average net returns based on 9 yrs of market data compared to a May calving system. These studies indicate the effect and importance of late gestation supplementation on cow and calf productivity in a spring calving herd. Cow-calf producers should carefully consider calving system utilization based on their unique production goals.

Book Description
Reducing weaning stress in beef calves can have dramatic benefits to the health, growth, and performance to beef calves post-weaning. Studies have shown that providing creep feed to calves during the pre-weaning period can improve their nutritional status, which can better prepare them for the stresses they will be exposed to during the weaning process. Studies have also shown that two-stage weaning can reduce the stresses associated with weaning. Previous research has suggested that this method resulted in dramatic changes in behavioral signs associated with stress. The objective of this study was to evaluate the effects of two-stage weaning with or without creep feed and creep feed without two-stage weaning on early-weaned spring-born beef calves. This study was done at the University of Arkansas SWREC in Hope, Arkansas, and consisted of 253 angus crossbreed cow-calf pairs in a spring-calving system over a two-year study (n = 140 in 2019; n = 113 in 2020). Following calving, all calves were randomly allocated to four different treatments in a 2 x 2 factorial arrangement. Treatment factors consisted of 1) nose flap vs no nose flap and 2) creep feed vs no creep feed. The four different treatment combinations were labeled as CON (control; no creep feed and no nose flap), NFC (nose flap with creep feed), NF (nose flap without creep feed), and CF (creep feed without nose flap). All measurements on performance were analyzed using the MIXED procedure of SAS. Significance was declared at P ≤ 0.05 and tendencies at 0.05.

Book Description
Creep feeding is the practice of providing nursing calves with the opportunity to eat feed to which the cows do not have access. This fact sheet provides information on the benefits of creep feeding, the role of creep feeding in calf nutrition, the weight gain achieved by calves given creep feed (either free choice conventional grain feed or limit-fed high-protein rations), the economics of creep feeding, the use of creep feeding as part of an effective weaning program, creep rations, and the feeding equipment used.
