“…One strategy to reduce cost is to extend the grazing season because allowing cows to graze costs less than mechanically harvesting and feeding forage. Selecting a calving date that matches the cow's nutrient requirements with grazed forage nutrient content has the potential to reduce costs (Adams et al, 1996;Stockton et al, 2007). Two critical decisions that cow-calf producers can make are season of calving and time of weaning.…”

The aim of this study was to explain the birth season effect on Hereford bulls fattening results. The research was made within the project 'Baltic Grassland Beef' framework in years 2015 and 2016. Data about 41 Herford purebred bull was used in the research, grown in different farms of Latvia. Bulls were slaughtered in certified slaughterhouse 'Agaras' (Lithuania). The average birth weight of the Hereford breed bulls was in border from 42.9 -45.0 kg. The lowest birth weight was on spring season born bulls -42.9 kg, but the highest on winter season born bulls -45.0. Average realization age of bull's, in the research groups, was on range from 567 days to 661 days. Bulls born on autumn and winter before slaughtering were significantly older, respectively 661 and 655 days with live weight of 519.9 kg un 542.1 kg. On spring born bulls with age 600 days reached the biggest live weight -542.0 kg, respectively these group bulls average daily weight gain from birth to slaughter per day was the biggest among all the groups -831.9 g. The highest slaughter weight showed on autumn and winter seasons born bulls, respectively 275.5 kg and 274.8 kg. In the research groups on different seasons born bulls conformation score was from points 2.4 to 2.6. All the bull's carcass in the research groups were evaluated as 2nd and 3rd fat class. between the age before slaughter and average daily weight gain from birth to slaughter there is an important negative correlation (from r = -0.858 to = -0.977, p<0.05), except on spring season born bulls.

“…The traditional late-winter calving system produces weaned calves and culls animals that are generally marketed when the average seasonal prices are least (USDA, 2010). Altering the calving date shifts production and market windows to a different time, which may be economically advantageous (Stockton et al, 2007). In addition to calving date, the decision to sell calves at various ages or BW provides flexibility in marketing and use of feed resources.…”

“…The EC offers a shorter calving period (Adams et al 2001;McCartney et al 2004;Landblom et al 2005;Durunna et al 2014b) and provides greater weight gains to both steers and heifers at weaning compared with late (summer) calving (LC). However, LC has been associated with potentially higher net revenues from lower system costs and higher beef prices (Stockton et al 2007;Griffin et al 2012;Khakbazan et al 2014); it also offers a better match between cow nutritional requirements and available pasture (Story et al 2000;McCartney et al 2004;Anderson et al 2005;Reisenauer et al 2007;Hughes 2008Hughes , 2009Lardner et al 2011). Economic consequences of LC versus EC will emanate from differences in feed sources, infrastructure requirements, labour requirements, and marketing options (Wolfova´et al 2005;Reisenauer et al 2007;Winterholler et al 2008;Girardin 2011;Khakbazan et al 2014).…”

The effects of spring versus summer calving on beef cattle economic performance in western Canada

. 2015. The effects of spring versus summer calving on beef cattle economic performance in western Canada. Can. J. Anim. Sci. 95: 475Á486. The choice of calving date influences the net revenue of a calving operation as it affects the number of days that calves spend in each feeding phase and when they are subsequently marketed. These two factors determine the costs, revenue, and risk (variance) of each calving system for the calving phase of a beef system. The majority of cowÁcalf producers in western Canada have adopted early calving (EC) in spring due to management factors. However, late calving (LC) in the summer is an alternative beef calving system associated with higher returns due to lower system costs and higher beef prices. It may offer a better match between cow nutritional requirements and pasture availability. The objective of this study was to compare the revenues and risks for a traditional EC system and an alternative LC system at three sites in western Canada. Biological and economic data from three field experimental sites in western Canada (Brandon Research Centre in Manitoba, Western Beef Development Centre in Lanigan, Saskatchewan and Semi-Arid Prairie Agriculture Research Centre in Swift Current, Saskatchewan) were used to determine the costs and benefits of the alternative beef calving system. The results showed that even though the EC has higher cost than the LC, the EC is slightly better than LC in terms of higher net revenue potential, but it comes at a greater risk due to higher revenue variances. The EC system is usually more preferable for risk-neutral producers, whereas the LC system is more preferable for risk-averse producers.
