“…Similarly, dehydration was not influenced by DM concentration. This agrees with the findings of Pettyjohn et al (1963) who used a milk replacer fed ad libitum at five levels of DM (5, 10, 15, 2O and 25%). Though Mylrea (1966) observed no change in fecal dry matter of calves fed whole milk ad libitum compared to restricted levels, Blaxter and Wood (1953) and Rojas et al (1948) As with fluid intake levels, DM concentration influenced weight changes of the calves slightly but not significantly (Table 5) …”

“…intake decreasing as the D.M. Pettyjohn et al (1963) also found that the utilisation of the D.M. The lambs consumed a significantly greater volume of liquid milk at the lower concentrations; although the voluntary intake of drinking water, which was available at all times, increased with increasing concentration, the total amount of water consumed decreased (see Table 1).…”

SUMMARY1. Six Dorset Horn lambs were reared on each of four different concentrations of reconstituted full-cream dried milk powder (10, 15, 20 and 25 % dry matter). The lambs were fed to appetite four times a day for 3 weeks.2. The lambs consumed significantly more liquid milk at the two lower concentrations. Intake of waterper seincreased with increasing concentration of dry matter.3. There were no significant differences in the consumption of milk dry matter between the treatments, although there was a significant linear trend, with dry-matter intake decreasing with decreasing concentration.4. There were no significant differences between the treatments in live-weight gain from 0 to 3 weeks or from 0 to 10 weeks.5. There were no significant differences in the efficiency of feed conversion between the treatments.6. Examination of the distribution of milk intake within days showed that the proportion of milk voluntarily consumed in the first feed of the day increased with age and with concentration.7. The incidence of scouring was high, but there was no general relationship with treatment.8. Abrupt weaning was not satisfactory for the lambs which had been offered only liquid food for 3 weeks and they had to receive a low level of milk feeding for a further week while they became accustomed to solid food.

“…Calves maintained on this feeding regime in the present trial (Group A) consumed their prescribed allowance to the age of 12 weeks (Table 3). Pettyjohn, Everitt, and Mochrie (1963) recorded even greater fluid milk intakes in 4-to 8-week-old Friesian bull calves by showing that voluntary consumption of a milk replacer containing 5% dry matter fed four times daily amounted to 38% of body weight per day or about 9.5% of body weight per feed.…”

“…They could have been caused by such factors as the curtailment of iron and copper supplementation. the development of some other micronutrient deficiency, or the activity of chemostatic control mechanisms on satiety (Pettyjohn et al 1963) which. at such a high level of feeding, begin to function only when the post-natal decline in metabolic body size relative to live weight reaches a crucial level.…”

An intake of spray-dried whole-ll)ilk powder equivalent to 2% of body weight was maintained in calves during the first 12 weeks of life when the powder was supplemented with iron, copper, and magnesium.Intakes relative to body weight declined after the age of 12 weeks when fortification with iron and copper ceased. Gradual increases in the dry-matter content of milk to compensate for the decline in abomasal capacity relative to body weight did not enhance intake between the age of 12 and 16 weeks.Supplementation of spray-dried whole-milk powder with iron and copper at levels of 46.7 and 5.1 mg/kg respectively maintained blood haemoglobin concentrations. Fortification of the powder with 0.25 g of magnesium per kg did not prevent, but appeared to delay, the onset of progressive hypomagnesaemia.An increase in the apparent digestibility of fat and a decrease in the digestibility of lactose and ash were noted with advancing age. Reconstitution rate did not affect the digestibility of milk nutrients up to the age of 16 weeks.
