A 3-yr study was conducted with spring-born heifers (n = 240) to determine the effects of developing heifers to either 55 or 60% of mature BW at breeding on reproduction and calf production responses. A concurrent study was also conducted with summer

Two experiments were conducted to determine whether extending the interval between removal of melengestrol acetate (MGA) from feed and injection of prostaglandin F2α (PGF) from 17 to 19 d would affect synchronization of estrus, conception, and pregn

This analysis evaluates the economic effect of using Synovex-C implants in the development of replacement heifers as compared to no implants. The analysis addresses the value of increased gain and weight vs the value or opportunity cost due to reduce

Two trials were conducted to evaluate effects of Synovex C implants on replacement heifers, given at two different ages. Crossbred heifer calves (n = 370) were allotted to four treatments: 1) nonimplanted controls, 2) implanted at 2 mo, 3) implanted

One hundred twenty crossbred yearling heifers were used to compare a combination of MGA and prostaglandin F 2 α (PGF 2 α) as an estrous synchronization program to a conventional Al program. Heifers were stratified by estrous status (prepuberal or p

Two hundred crossbred yearling heifers were used in a 3 x 2 factorial experiment to compare the effectiveness of two estrous synchronization programs (MGA-prostaglandin F 2 α and Syncro-mate-B) with a control group utilizing two types of breeding pr

A study was conducted over 3 yr to evaluate effects of sire birth weight EPD, calf birth weight and shape, and heifer pelvic area and weight, individually and in combination, on dystocia and subsequent rebreeding of 2-yr-old heifers. Heifers (n = 550

A 5-yr study was conducted beginning in 1983 with 460 cows to evaluate the effects of three breeding seasons (30, 45, and 70 d in length) and two times of spring calving, March (early) and April (late), on cattle production under Nebraska Sandhills r

The objective of this study was to determine whether a combination of Cu, Co, Mn, and Zn in an organic or inorganic form fed at higher than nutrient recommendations for 2-yr-old cows from calving to breeding would affect pregnancy rate, calving date,
