2012 - Limit-feeding concentrate diets to beef cows as an alternative to feeding hay
During drought forage production is reduced and hay prices are typically high. Comparison of grain and forage prices on a cost per unit of energy (net energy of maintenance or TDN) may reveal that it is less expensive to supply nutrients to maintain and grow cattle by feeding concentrate feeds rather than roughage. Only a small amount of roughage is fed in conjunction with the concentrate portion of the diet, resulting in a nutrient dense diet. It is important to note that although the cow or calf is being fed a smaller amount of feed they will be receiving the same amount of nutrients as if they had consumed their diet by being allowed to graze or fed ad libitum hay.
2012 - Daytime Calving
Stimulating more cows to give birth during daylight hours can be accomplished by late afternoon or evening feeding. Research conducted at the K-State Agricultural Research Center in Hays demonstrated that when cows were fed daily between 4 p.m. and 6 p.m. 85% of their calves were born between 6 a.m. and 6 p.m. In addition, it was observed that cows which calved during daylight hours tended to give birth during daylight hours in future years.
