“…Ease of calving probably reflects the sire genotype as was suggested by Roux et al (1987), who used eitherAberdeen Angus or Aubrac sires on Friesian or Charolais x Friesian heifers and by Harte (1987), who used Hereford x Friesian heifers and Aberdeen Angus bulls. Puntila et al (1985) reported that HfAy-heifers had marginally greater calving difficulties than LiAy-heifers calving to a Limousin sire.…”

“…Therefore, they were mated at an average weight of 287 kg at 15 months of age in November 1989. Roux et al (1987) achieved liveweights at mating of 253 kg for 10-12 month old Friesian heifers, and 288 kg for Charolais x Friesian heifers of the same age, under a feedlotting system in France.…”

“…Although the performance of maiden and once-calved heifers has been compared in overseas studies (Boucque et al 1980;Roux et al 1987;Waggoner et al 1990; Keane et al 1991), these studies were conducted on heifers reared in a mixture of indoor (concentrate feeding) and outdoor (concentrate/forage feeding) systems in Europe and North America. For New Zealand, no data on complete OBH beef production systems have been published.…”

The once-bred heifer beef production system involves mating heifers at 15 months of age to calve as 2-year-olds. This study compared the performance of once-bred Hereford x Friesian heifers mated to Limousin or Charolais sires and the herbage intake of once-bred and never-bred heifers during periods corresponding to late pregnancy and early lactation in the former group. Heifers carrying Limousin-sired (LS) calves had gestation lengths slightly longer than those carrying Charolais-sired (CS) calves (290.4 versus 286.6, pooled SE (PSE) = 1.2 days, P < 0.10), but there was no effect of calf sex on gestation length. The average birth weight of calves was 40 ± 1 kg, there being no difference between female and male, or LS and CS, calves. Dystocia caused mortality rates of 19% in calves and 9% in heifer dams. Female calves had 9 kg lower weaning weights at 142 days of age than male calves, whereas the CS calves had greater weaning weights than LS calves (218.3 versus 204.9 kg, PSE =3.6 kg, P < 0.01). Dam weaning weights were 443.5 versus 394.7 kg (PSE = 9.5 kg, P < 0.01) and 437.5 versus 400.7 kg (PSE = 9.5 kg, P < 0.05) in heifers suckling female versus male and LS versus CS calves, respectively. During late pregnancy, pregnant heifers had similar ingestive behaviour, herbage intake, and liveweight gains to never-pregnant heifers when offered a restricted pasture allowance of 7 kg dry matter (DM)/head per day. During early lactation, however, never-pregnant and lactating heifers consumed 9.19 versus 11.36 kg organic matter (OM)/head per day, (PSE = 0.63 kg OM/head per day P < 0.05) at a pasture allowance designed to permit ad libitum intakes. During this period, liveweight gains of 1.70 versus 0.61 kg/day (PSE = 0.28 kg/day, P < 0.05) were recorded for the neverpregnant versus lactating heifers. Results are discussed in the context of beef production from unbred and once-bred heifers.

“…Nearly all DMBB heifers are used for the replacement of culled cows. This production system can be considered as an extended form of beef production with early calving heifers (Roux et al, 1987), with two to three calvings per cow on average to generate a sufficient number of replacement heifers to maintain the size of the cow herd. The lower BWY in older cows was only partly compensated by a heavier calf BWb.…”

Factors affecting calving interval (CI) in double-muscled Belgian Blue (DMBB) beef cows were investigated with regard to the BW yield (BWY) of the cow-calf pair, using 834 CI records from 386 females with parities 1 to 6. The effect of parity and CI on BWY was also studied. Cow-calf pair BWY was defined as calf birth weight plus dam BWY per CI. CI (mean ± s.e.: 404 ± 1.9 days) was affected by parity, calving season, suckling and calf birth weight/dam weight. Primiparous cows had a shorter CI than cows with three or more calvings (P < 0.05), with an intermediate CI for second-calf cows. Spring calvings resulted in a shorter CI than summer and autumn calvings, with intermediate values for winter calvings. Suckling dams had longer CIs than non-suckling dams. There were interactions (P < 0.05) between calving season and suckling, and between calving season and mating system. Shortest CIs were observed for spring calvings in case of non-suckling and for summer calvings in case of suckling. Longest CIs were observed for autumn calvings in case of natural service (NS) and for winter calvings in case of artificial insemination (AI). Calf birth weight/dam weight of 6% to 10% resulted in shorter CI than a ratio of <6% ( P < 0.05). Body condition and mating system (NS v. AI) did not affect CI. Daily cow-calf pair BWY was affected by parity ( P < 0.001) and CI (P = 0.013), with a tendency for an interaction (P = 0.094). Daily cow-calf pair BWY did not differ for CIs of <12 to 16 months in primiparous cows and was lowest for a CI of 13 to 15 months in second-calf cows, whereas the effect of CI was more variable in older cows. Dam contribution to cow-calf pair BWY was larger than calf birth weight in first-and second-calf cows, and increased with increasing CI. Dam contribution to cow-calf pair BWY was smaller than calf birth weight in older cows, varying from 0.2 to 1.0 depending on CI. A short CI is advised for DMBB cows because of a larger BWY and more efficient nutrient utilisation.
