A Systems Approach to Production From Weaning to Harvest

چکیده
Introduction Although some summer and fall calving occurs, most calves in the northern states are born in the spring. Therefore, to have a consistent supply of feeders entering feedlots, a variety of stocker programs are used. About 30% of calves produced in the U. S. enter the feedlot as calf-feds. Some of these calf-feds are weaned and enter the feedlot 30 to 40 days later. It is also common for calves to be backgrounded two to six months before entering the feedlot. Many calves enter yearling programs. These cattle are nutritionally restricted to varying degrees and for various times. They make compensatory gain on grass and then make additional compensatory gain when they enter the feedlot. Because of the great variety of cattle production systems, cattle enter the feedlot at varying weights, ages and nutritional backgrounds. Ranchers have an opportunity to add value to their calves by backgrounding them. Ranches have forage resources. It may be possible, in some cases at least, to optimize the use of those forage resources by backgrounding calves produced on the ranch. We have conducted research on backgrounding programs over the past 15 to 20 years. We also feed 600 or more calf-feds each year. We want to share those observations and the appropriate economics with you.

A hierarchical approach for designing the downstream segment for a supply chain of petroleum production systems
Strategic decisions in a supply chain are the most important decisions for petroleum production systems. These decisions, due to high costs of transportation and storing, are costly and affected by the tactical and operational decisions in uncertain situations. In this article, we focus on designing a downstream segment for a supply chain of petroleum production systems. For this purpose, we wi...

To determine the value of pre-pubertal plan of nutrition on reproductive performance, hormonal concentrations and milk production in ewe lambs, a total of 40 clinically health Kurdish female lambs (30±8.6 d and weighing 10.2±3.4 kg) were randomly allocated to one of two experimental diets in pre-weaning period: high quality diet (HQD) (HQD, 2.50 Mcal ME/kg dry matter (DM) and 148 g CP/kg DM) or...

This study was aimed at analyzing the yield, grain quality and weed infestation of spring triticale sown in 3 tillage systems: a) conventional tillage (CT)-shallow ploughing and harrowing after harvest of the previous crop, ploughing in the autumn; b) reduced tillage (RT)-only cultivator after harvest of the previous crop, and c) no-tillage (NT)-only glyphosate (360 g L-1) after harvest of ...
متن کاملPost-Weaning Performance of Steers from Varying Calving and Weaning Strategies in Montana1
The impact of varied calving and weaning times on post-weaning production of steer calves was evaluated in a 3yr study. Steers (approximately 12 steers per calving-weaning treatment per year) born in late winter or early spring were weaned at 190 or 240 d of age, and steers born in late spring were weaned at 140 or 190 d of age after grazing with their dams on native range. Steers were pen-fed ...
متن کاملTwo-stage Production Systems under Variable Returns to Scale Technology: A DEA Approach
Data envelopment analysis (DEA) is a non-parametric approach for performance analysis of decision making units (DMUs) which uses a set of inputs to produce a set of outputs without the need to consider internal operations of each unit. In recent years, there have been various studies dealt with two-stage production systems, i.e. systems which consume some inputs in their first stage to produce ...

A 4-yr study using 217 cows/yr (3/4 Red Angus, 1/4 Simmental) evaluated effects of calving date and wintering system on cow and calf performance from birth to harvest. Cows were assigned to 1 of 5 treatments: 1) March (Mar) calving cows wintered on native range, 2) Mar calving cows wintered on corn residue, 3) June (Jun) calving cows wintered on native range, 4) Jun calving cows wintered on cor...
