2. Can utilize entire production of grains and roughages on a farm 3. Can utilize land unsuitable for other agricultural commodities 4. Small investment in facilities and equipment (especially in cow/calf) 5. Small risk of loss due to animal death 6. Beef is the most popular meat in the US on a boneless basis. The cow‐calf phase in all three production systems is the greatest contributor to resource use and emissions in beef production. On a per‐kilogram basis of live weight production, impacts in all four categories were highest in the pasture‐based system and the lowest in the feedlot system.

James Walsh, an upstate New York Republican who received over $65, from agriculture industry interests in the election cycle, introduced the amendment to force the USDA to conduct.
Twinning has clear potential to increase the biological efficiency of beef production. Selection for increased ovulation and twinning rates in cattle has been successful. VanVleck and Gregory () report that the frequency of twinning increased with selection from % in to % in (Figure 1). Current frequency of twinningFile Size: KB. The annual production cycle of beef cows. Phase 1. Day zero of the production cycle is parturition (calving), with phase 1 continuing through the postpartum interval, and concluding with at the time of conception. This phase is the most critical in terms of setting the stage for the remaining four phases. With a day production cycle, and.

This article reports results from the fourth cycle of the Germplasm Evaluation (GPE) Program at the Roman L. Hruska U.S. Meat Animal Research Center (MARC). The program’s. The environmental impact of food products is increasingly quantified using LCA.
In an LCA of beef, resource use and emissions from all production stages are quantified, assigned to environmental impact categories and related to the main output of the system, e.g.
1 kg of live weight, slaughter weight or edible nmental impacts generally considered in LCAs of animal-source food are Cited by: Time in Cycle: months The beginning stage of life for both grass-finished and grain-finished cattle is the same for the first months of the animal’s life.
All beef cattle eat grass for at least the first half of their lives. The three main stages in beef production are: cow-calf farming or ranching - These producers maintain herds of mature cows, mate these and raise the calves to weaning age (around six months). stocker production or backgrounding - In this stage the weaned calves are grown on forage and/or pasture for a further six to 12 months.
ANNUAL BEEF CATTLE PRODUCTION CYCLE It is obvious that the timing of events in an annual beef cattle production cycle are tied to each other. Once the breeding season is established, the time of calving, weaning, availability of replacement heifers and stockers, next year's breeding season, preventative medicine programs, etc.

A life cycle assessment (LCA) was conducted to estimate whole-farm greenhouse gas (GHG) emissions from beef production in western Canada. The aim was to determine the relative contributions of the cow–calf and feedlot components to these emissions, and to examine the proportion of whole-farm emissions attributable to enteric methane (CH 4).The simulated farm consisted of a beef production Cited by: Per Capita Beef Consumption in %.

A deterministic beef efficiency model (BEM) was used to evaluate life-cycle herd efficiency (LCHE) in cow-calf beef production systems using four breed groups of beef cattle. The breed groups were Beef Synthetic #1 (SY1), Beef Synthetic #2 (SY2), Dairy Synthetic (DS), and purebred Hereford (HE).
