“…Slaughter and histopathological data also reflected no effect of dietary iron treatment, except that carcass grade was-as expected (Niedermeier et al, 1959;Bremner and Dalgarno, 1973;MacDougall et al, 1973)-related negatively to iron intake.…”

“…Dietary iron supplementation is an aspect of veal calf welfare that has not been studied using multiple criteria. Limiting iron intake can affect a calf's blood composition (Blaxter et al, 1957;Roy, 1980;Reece et al, 1985) and carcass quality (Niedermeier et al, 1959;Bremner and Dalgarno, 1973 ;MacDougall et al, 1973). However, whether low iron intake influences certain other physiological, behavioral, pathological or production characteristics is not known.…”

Holstein calves were managed from less than 1 wk of age as in the special-fed veal industry but subjected to three dietary regimens (n = 10/group): low dietary iron (LI = approximately 5 mg iron/kg dry milk replacer) throughout 16 wk; 2) high then low dietary iron (H-LI = 140 mg/kg through d 18, then approximately 5 mg/kg through wk 16; a typical industrial scheme) or 3) high dietary iron (HI = approximately 105 mg/kg throughout the study). Several physiologic, behavioral and health indicators of welfare were monitored at various times. From wk 7 on, blood hemoglobin concentration was higher in HI calves than in LI, whereas that in H-LI calves was intermediate. Blood red cell count was higher in HI calves than in LI from wk 11 to 16, and was higher in HI than in H-LI from wk 14 to 16. Ratio of blood segmented neutrophils to lymphocytes (an indicator of stress) did not differ due to dietary regimen. Between wk 2 and 16, lying time increased from 69.5 to 76.6% of total time. Oral behaviors (e.g., licking and gnawing) occupied less than 15% of total time. Dietary regimen did not affect time spent either lying or engaging in oral behaviors. Calves in all dietary-regimen and slaughter-age groups experienced high frequencies of pneumonia, digestive-tract maladies and trichobezoars, but neither disease nor medical-treatment frequency was related to dietary regimen. Live, hot-dressed carcass and liver weights of the five calves/group slaughtered at 16 wk were not affected by dietary regimens, but carcass grade was highest for LI calves and lowest for HI.(ABSTRACT TRUNCATED AT 250 WORDS)

“…Charpentier (1964) reported that iron dextran supplementation increased total muscle pigment, but St-Laurent and Brisson (1967) obtained no effect from iron supplementation on muscle haemoglobin or myoglobin in 60-day calves, and concluded from biopsy samples that age was the major determinant of pigment content. Roche (1961) andNiedermeier et al (1959) claim that iron supplementation is undesirable in calves intended for veal because the pale pink flesh from unsupplemented calves is considered more desirable. However, only Bray et al (1059) and St-Laurent and Brisson (1967) have attempted to relate pigment content (myoglobin, haemoglobin, or total pigment) to objectively measured muscle colour, and the present authors are aware of no study which has attempted to relate muscle colour, measured chemically or otherwise, to objectively measured consumer acceptance.…”

Forty-two Friesian bull calves were allocated to two treatments; the animals in one group were individually penned and fed indoors. and those in the other were penned in groups of seven under a lean-to on wooden shavings. The calves were fed reconstituted commercial milk powder for 12 weeks and were then slaughtered.The feed intake and carcass growth of the calves on both treatments were very similar, but the lean-to calves were 5 kg heavier in starved live weight at slaughter, largely because of increased gastrointestinal fill resulting from eating wood shavings. The cut-out data on the carcasses indicated similar composition for the two treatments, with the exception that the calves fed indoors had a higher proportion of perinephric and channel fat, and a slightly greater fat cover and a lower eye muscle area than the lean-to calves.Blood haemoglobin and muscle colour and pigment measurements showed that the calves were not anemic, but the m, longissimus dorsi was very pale. The necessity for anaemia in order to produce white veal of suitable muscle colour is questioned.

The colour and pigment concentration of muscles from veal calves whose dietary iron intake was 10, 40 and 100 μg/g milk powder were measured. The colour was related to pigment content which was related to the dietary iron concentration and anatomical location of the muscle. The myoglobin content of veal from calves receiving 100 μg Fe/g was twice that of veal from calves receiving 40 μg Fe/g but there was no difference in myoglobin content between 10 and 40 μg Fe/g. Calves receiving 10 μg Fe/g contained less haemoglobin in their blood. The lightness of cooked veal was found to be linear with the lightness of the raw, with little change in saturation but a large change in hue.
