Performance Efficiency of Pasture-raised Primiparous Beef Cows of Three Different Biotypes and Two Milk Production Levels
(Universidade Federal do Rio Grande do Sul, 2017)
Risks associated to different methods of increasing pregnancy rate of cows in cow-calf systems
(Brazilian Journal of Animal Science, 2023)
Feed technologies and efficiency in cow-calf systems

Use of supplements and variation in the stocking rate in cow-calf systems on temperate pastures in Chile: a simulation approach
(CSIRO PUBLISHING, 2009)
A simulation model was developed to evaluate the productive and economic effect of the variation in feed practices and stocking rate of a cow-calf system in Chile. Winter supplementation at grazing, stocking rate and ...
Effects of organic or inorganic cobalt, copper, manganese, and zinc supplementation to late-gestating beef cows on productive and physiological responses of the offspring
(Amer Soc Animal Science, 2016-03-01)
Eighty-four multiparous, nonlactating, pregnant Angus x Hereford cows were ranked by pregnancy type (56 AI and 28 natural service), BW, and BCS and allocated to 21 drylot pens at the end of their second trimester of gestation ...
Backgrounding strategy effects on farm productivity, profitability and greenhouse gas emissions of cow-calf systems in the flooding pampas of Argentina
(Elsevier, 2019-11)
Beef grazing systems need to improve their environmental sustainability while increasing productivity to meet future demand. In a context of climate and prices variability, the main aim of our study was to explore the ...
An innovation path in Argentinean cow-calf operations: Insights from participatory farm system modelling
(John Wiley & Sons Inc, 2020-04-15)
The information of how the high climatic variability in the south-west Buenos Aires Province (SWBS) region, Argentina, impacts on existing cow–calf operations is needed. This research uses a combination of quantitative ...
Bio-economic evaluation of a reduced phosphorus supplementation strategy for a cow-calf system in Brazil: a case study
(2018-01-01)
Fertility, weight of calves at weaning, and the economic aspects of a breeding herd receiving mineral supplements containing 75 or 12.5 g of phosphorus (P)/kg were measured from 2013 to 2016. No differences in reproduction ...
Cow/calf preweaning efficiency of Nellore and Bos taurus x Bos indicus crosses
(AMER SOC ANIMAL SCIENCE, 2009)
The objectives of this study were to determine if percentage Bos taurus (0 or 50%) of the cow had an effect on ME requirements and milk production, and to compare cow/calf efficiency among 3 mating systems. Metabolizable ...
