“…The lower BCS of primiparous cows and the smaller change of BCS observed in this study were in accordance with the estimation of body composition of BBDM cows [9]. On the contrary, a larger BWchange was found in these cows.…”

“…Data analysis was based on a regression between BCS-change and BWchange, or a regression between BCS and BW, respectively. However, some components of non-adipose body growth are included within the estimate of BW-change in both cases [9,28]. While only mature cows were involved in the experiment of Wright and Russel [28], about one third of the data were from primiparous cows in our experiment.…”

“…Therefore, its applicability in the latter animals may be questionable, since ribs, hips, backbones and tail head tend to be embedded in a muscle mass rather than in adipose tissue. Nevertheless, a good relationship was found between BCS (body condition score) in double-muscled cows and the chemical composition of the empty body weight [9].…”

-The relationship between the body condition in Belgian Blue double-muscled cows and the performance of cows and calves has been studied over a 5-year period. One hundred and twenty-six cows, with a mean initial parity of 1.6 ± 1.1 were involved. During each winter, they were fed 100, 90, 80 or 70% of their energy requirements (140-day restriction period). At the end of April, all cows were turned out on pasture in identical circumstances (re-alimentation period). Half of the cows were suckled by their offspring; the other cows were dried off following calving and colostrum collection. Body condition score (BCS; scale 0 to 5) was determined at the start and end of the restriction period and the re-alimentation period, at monthly intervals and at calving. Two hundred and thirteen parturitions were involved, of which 63% occurred during the first half of the year. BCS (mean of monthly observations) was lower (P < 0.001) in primiparous (1.45) cows than in cows with two (1.69) or more parturitions (1.81). BCS (mean of monthly observations) was lower in suckling cows (1.51) than in dry cows (1.79; P < 0.001). BCS (mean of monthly observations) was reduced by energy restriction from 1.75 to 1.56 (P < 0.001). BCS-change during the restriction and re-alimentation periods was related to body weight change (R 2 = 0.538). BCSchange was negative during the restriction period, but it was more than compensated for during the re-alimentation period. BCS at calving was not related to the length of the subsequent calving interval. Cows with a BCS less than 1.5 at calving, yielded less milk and calf performance was reduced when compared with those with a BCS over 1.5. The dams of calves that died at birth had a lower BCS at calving (1.45) than the dams of surviving calves (1.75; P = 0.044). Open cows at 9 months postpartum had a higher BCS at calving (1.78) than cows that became pregnant within 9 months postpartum (1.50; P < 0.001). Consequently, it is difficult to define a universal optimum BCS for double-muscled cows, resulting in a maximal milk production and calf growth, a low calf loss and cow culling rate and a calving interval of approximately one year. (140 jours ; période de restriction). Toutes les vaches ont été mises au pâturage dans des conditions identiques à partir de la fin avril (période de compensation). La moitié des vaches ont allaité leur veau, tandis que les autres vaches ont été taries après collection du colostrum. La NEE (0-5) était déterminée au début et à la fin de la période de restriction et de la période de compensation, chaque mois et aussi au moment du vêlage. Il y avait 213 vêlages, dont 63 % pendant la première moitié de l'année. La NEE (moyenne des observations) était plus faible (P < 0,001) chez les primipares (1,45) que chez les vaches à deux (1,69) ou plus de vêlages (1,81). La NEE (moyenne des observations) était plus faible chez les vaches allaitantes (1,51) que les vaches taries (1,79 ; P < 0,001). La NEE (moyenne des observations) a été réduite de 1,75 à 1,56 par une restriction ...

“…Requirements for gestation were based on requirements reported by CVB (1998), and increased according to the predicted calf BWb (NRC, 1996). Tissue composition of dam BWY was based on body composition of DMBB cows (Fiems et al, 2005b). Prices for energy (20.27€/GJ net energy) and protein (1.17€/kg protein digested in the small intestine) were assumed based on the information of Wageningen UR (http://www.wageningenur.nl/nl/Expertises-Dienstverlening/ Onderzoeksinstituten/livestock-research/Faciliteiten-producten/ Voederwaardeprijzen-Rundvee.htm).…”

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.

The use of culled potatoes was investigated in Belgian Blue double-muscled finishing cows, confined in tie stalls. The control diet (Treatment 1) consisted of concentrate and maize silage (50/50 on a dry matter (DM) basis). Potatoes either replaced 60% maize silage (Treatment 2) or 60% concentrate (Treatment 3). Diets were formulated to be isocaloric and isonitrogenous. They were fed ad libitum. Approximately 18 kg potatoes were fed daily in Treatments 2 and 3. Daily gain was not significantly altered; it decreased from 1.09 kg (Treatment 1) to 1.04 kg (Treatment 2) or increased to 1.20 kg (Treatment 3), although potatoes stimulated DM intake by 5% to 8% ( P , 0.05). Feed conversion was unaffected in comparison with the control diet, when expressed in terms of DM, but energy efficiency (MJ/kg live weight gain) was substantially lower for Treatment 2 compared with Treatment 1 (89.9 v. 79.0; P 5 0.046). Carcass weight, grading and composition were not affected by treatments, but potatoes increased dressing percentage ( P 5 0.009). Treatment had no significant effect on meat quality parameters. However, potatoes (Treatments 2 and 3) tended to decrease moisture content ( P 5 0.090) and tended to increase drip loss ( P 5 0.059) compared with Treatment 1. Because of a better animal performance and a lower feed cost, it is most appropriate to use potatoes as a replacement for concentrate. Feeding large amounts of potatoes besides concentrate may have an adverse effect on the fibrousness of the diet, resulting in a tendency (25%) for a reduced daily gain and a lower energy efficiency ( P , 0.05).
