PROFITABILITY OF ESTABLISHING BASIN WILDRYE FOR WINTER GRAZING [PDF]

This study examined the economic viability of establishing basin wildrye for winter grazing. Mixed integer-programming models were developed that minimized cow feed costs. Estimated basin wildrye establishment costs were $154 per acre.

The Effect of Early vs. Normal Calf Weaning on Feedlot Performance and Herd Management: A Cross-Discipline Case Study [PDF]

A study of early vs. normal weaning of calves concludes that early weaning improves feedlot production efficiency, reducing per day and per pound feedlot production costs.

OPTIMAL FEED COST STRATEGIES ASSOCIATED WITH EARLY AND LATE CALVING SEASONS [PDF]

Integer programming models were used to examine optimal monthly feeding strategies and costs for March and May calving alternatives. Body condition scores were allowed to fluctuate throughout the year except for calving and breeding periods.

BLACK OAT (Avena strigosa) SILAGE FOR SMALL-SCALE DAIRY SYSTEMS IN THE HIGHLANDS OF CENTRAL MEXICO

Tropical and Subtropical Agroecosystems, 2018
Black oat (Avena strigosa cv. Saia) silage (BOS) as an alternative forage for the dry season in small-scale dairy systems was evaluated against maize silage (MSL) at 6.0 kg DM/cow/day.

Estimating Body Condition Score of Cows from Images with the Newly Developed Approach

, 2017
The Body Condition Score (BCS) is the level of energy reserves in many species, including dairy cattle. For the exact management on dairy farms, the judgment process of BCS is critically important.
