“…We found, in agreement with the results of other authors (Marsh, 1976;Zduhczyk and Lewicki, 1989), that limiting the ration of concentrate stimulates the intake of silage (the ratio of dry matter intake from concentrate to that from roughage in groups H and S was similar and equalled 1.3 and 1.4, respectively), and the silage, in spite of its low DM content (18.9%) was comparable to hay as a source of nutrients for the calves.…”

“…However, it has been demonstrated that good quality grass silage can be included in hay-free diets for young calves even of the age of two weeks (Bartholomew etal., 1981;Marsh, 1975Marsh, ,1976. According to Marsh (1975) when fattened calves were provided with limited amounts of concentrates and grass silage fed to appetite, satisfactory weight gains were achieved and 35% less concentrate was consumed in comparison with traditional feeding regimens.…”

Black-and-White bull calves aged 14 to 91 days were fed rations differing in the type of roughage offered to appetite: hay (group H) or meadow grass silage (group S) with 2 kg 80% formic acid/ton of fresh forage. Before weaning (days 14-42 of age), the average daily intake of roughage dry matter and gross energy per kg 0 ' 73 was higher (P^0.05) in group H than in group S (45.0 g and 1.1 MJ, vs. 41.1 g and 1.0 MJ, respectively). However, the differences in daily weight gains (623 and 583 g in groups H and S) and feed utilization were not significant. After weaning (43 to 91 day of life), mean daily intake of nutrients and total energy was similar in both groups with daily weight gains reaching 478 and 502 g, respectively for group H and S. Mean body weight gains during the entire experimental period were the same in both groups and equalled 530 g.The system of nutrition introduced in the present experiment may be useful for the rearing calves designed for future fattening based on roughages. However, due to the low level of Mg observed in blood plasma (0.38 mmol/1) of all the calves, the ration ought to be supplemented with a mineral mixture containing magnesium.

“…Krosowski and KTosowska (1984) and KTosowski et al (1988) reported that the faster the animals' growth as affected by feeding, the larger the fibre diameter and higher the percentage of FTG fibers. In growing calves reared on hayfree low-concentrate diets based on grass silage, satisfactory gains have been reported (Marsh, 1975(Marsh, , 1976Bartholomew et al, 1981;Bidwell-Porgbska et al, 1987;Piotrowski et al, 1988) (Ziegan, 1979 (Brooke, 1970) In the younger calves the intake of crude protein (CP) and gross energy (GE) was also slightly higher in the SD fed group. In the older animals the daily intake of GE was considerably higher, while the intake of CP was lower in the SD than in the HD fed group (table I).…”

Summary ― Samples of musculus longissimus dorsi, semimembranosus and semitendinosus were obtained post-slaughter from 2-week, 3-month and 10-month-old bull calves. The 2-week-old calves were fed milk only. All the remaining animals were fed grass silage or hay ad lib and a restricted amount of concentrate from 2 weeks of age onwards. Muscle fibres were differentiated according to Ziegan into fast-twitch glycolytic, fast-twitch oxidoglycolytic and slow-twitch oxidative fibres (FTG, FTO and STO, respectively). In all calves, marked fibre growth took place between 3 and 10 months of age. From the 2nd week to the 3rd month, growth was observed virtually only in the FTG fibres, irrespective of feeding. Feeding calves with a silage-based vs hay-based diet resulted in thicker muscle fibres for each type of fibre. Significant linear regression coefficients have shown the fibre diameters to be clearly related to live weight gain resulting from DM intake that was higher in the silage-based diet.calf / skeletal muscle fibre / silage / hay Résumé ― Microstructure des muscles squelettiques chez les veaux à l'ensilage ou au foin.

Three experiments were carried out to investigate the effect of different forage types on the performance of male British Friesian calves up to 6 months of age. Unwilted and wilted silages were compared in all experiments, and in experiment 1 hay was also compared with the two silages. All the forages were compared at different levels of concentrate supplementation ranging, in different experiments, from none to ad libitum.Calves fed wilted silage consumed 490, 90 and 200g/kg more forage dry matter respectively than those fed unwilted silage in the three experiments but this extra intake was generally not reflected in an increased rate of gain. Hay which was of lower digestibility than silage gave significantly lower live-weight gain. Quantities of silage consumed at an early age were small, with a mean daily intake over the first five weeks of 0·13 kg dry matter. Concentrate reduced silage dry-matter intake by 0·49 kg/kg concentrate dry matter consumed. Estimated mean concentrate intake required to achieve a daily gain of 0·75 kg in 1- to 6-month-old calves with silage offered ad libitum was 0·83 kg dry matter.
