Data on Pregnancy rates, calf weaning weights, and sale prices on the University of Nevada Agricultural Experiment Station’s Gund Ranch from 2008-2020

The University of Nevada Agricultural Experiment Station’s Gund Ranch near Austin, Nevada is approximately 100,000 acres with grazing by 325 cow-calf pairs. Cows are mostly Angus (80%) and Hereford (20%). Bulls are Angus X Hereford. Calves are mostly Angus with some black baldies. Cattle graze a Bureau of Land Management (BLM) grazing permit from April through July. Calving starts about mid-April. Branding is planned for 90-100 days after birth with bull calves castrated as this time. Privately-owned meadows are grazed July-September with weaning starting on September 15. Cows are grazed on BLM low elevation shrublands and weaned calves are kept in meadows with supplemental hay feeding on the Gund Ranch from October 1st through January 1st. The calves not kept for replacements are gathered and weighed for a total herd weight and shipped approximately the 1st of November. The larger end of the steers and heifers typically range from 475-490 pounds. Around 100 head are loaded onto a semi to achieve a full truckload of 48,000-50,0000 pounds. The smaller end of the steers and heifers are shipped on a second semi load. Weights are decreased with a 2% shrink calculation. In Nevada, there are only two sale barns, so many ranches receive more money by selling semi loads shipped to grazinglands of buyers’ choice. Calves are primarily sold on the internet go through Roundup Cattle Company. In years with drought conditions, calves may not reach the 48,000-50,000 weight limit for a second truck. Thus, the smaller calves can be marketed through a local sale barn at a one of their special calf sales.

位于内华达州奥斯汀附近的内华达大学农业实验站Gund牧场，占地面积约为10万英亩，拥有325对牛犊。牛群主要以安格斯牛（80%）和黑道牛（20%）为主，公牛则为安格斯牛与黑道牛的杂交品种。小牛主要为安格斯牛，其中夹杂部分黑色无毛牛。牛群在4月至7月期间持有美国土地管理局（BLM）的放牧许可证进行放牧。产犊期大约在4月中旬开始。在出生后90至100天内进行烙印，此时对公牛犊进行阉割。私人拥有的草场在7月至9月间放牧，断奶期始于9月15日。母牛在BLM的低海拔灌木丛地带放牧，断奶后的牛犊则被留在草场，并在Gund牧场从10月1日至次年1月1日期间补充喂养干草。不再用作繁殖的小牛被收集并称重，以计算总群重，并大约在11月1日时被运出。公牛和小母牛中体型较大的一端通常重量在475至490磅之间。大约100头牛被装上一辆半挂车，以实现48,000至50,000磅的整车装载量。体型较小的一端则被装在第二辆半挂车上。根据2%的缩水计算，重量会有所减少。在内华达州，仅有两个销售牲畜场，因此许多牧场通过将半挂车运往买方选择的放牧地以获得更多的收入。小牛主要通过互联网销售，并通过Roundup Cattle Company进行。在干旱年份，小牛可能无法达到48,000至50,000磅的第二次运输重量限制，因此体型较小的小牛可以通过当地销售牲畜场在他们的特别小牛销售中进行销售。本数据集由内华达大学雷诺分校、内华达农业实验站和美国农业部资助。数据集包含的资源包括：
