“…Before weaning, the low-fed calves visited the concentrate feeder more frequently, occupied it more, and consumed more concentrates, but had a lower daily gain (Table 2) than the high-fed calves. A lower daily gain was also found in Holstein-Friesian calves offered 4.1 compared with 6.7 kg of whole milk/d from birth to 7 wk, in which average daily gains of 538 and 615 g/d, respectively, were reported (Huber et al, 1984). Thus, the increased intake of concentrates could not compensate for the lower milk intake.…”

Calves fed by computer-controlled milk feeders are often weaned gradually by reducing the size of the milk portions. However, reducing the number of milk portions instead may lower calves' occupation of the milk feeder and stimulate their concentrate intake, especially when they are offered a high milk allowance. Before weaning, but not during weaning, the calves on low milk allowance occupied the milk feeder more, consumed more concentrates, and had a lower daily gain. There was no interaction between milk allowance and weaning type. Weaning by reducing the number of milk portions resulted in more unrewarded visits to the milk feeder, but less time ingesting a similar amount of milk. The effect of milk allowance on milk feeder occupancy before weaning was not found when this allowance was halved during weaning.

“…Greater starter intakes before weaning ensure that weight gains and intakes will be sustained after weaning (Kertz et al, 1979). These recommendations are in contrast to numerous studies that have demonstrated calves fed greater intakes of milk solids as well as greater protein concentrations in MR have greater DMI, ADG, and overall skeletal measurements, (Appleby et al, 2001;Jasper and Weary, 2002) but calves consume less starter, which can lead to a more stressful time during weaning and less rumen development (Huber et al, 1984;Cowles et al, 2006;Hill et al, 2010;Guindon et al, 2015), which places this type of program in direct opposition to the conventional calf management described above. Currently, an intensified optimum MR with CP levels greater than the 20% found in conventional MR is being fed to calves, which more closely resembles whole milk (Diaz et al, 2001).…”

Studies have shown that calves fed milk replacers (MR) with crude protein (CP) concentrations greater than 20%, as typically found in conventional MR, have higher dry matter intakes (DMI) and greater average daily gains (ADG) but consume less starter, which can lead to stress during weaning and reduced rumen development. The greater amount of CP being fed to preweaned calves may alter their nitrogen (N) balance, and excess N may be excreted in the urine. The objective of this study was to determine N utilization in preweaned calves fed diets varying in the amount of CP and MR fed. This study used 24 newborn dairy heifer calves blocked by birth and randomly assigned to 1 of 3 treatments: (1) 446g dry matter (DM) of a conventional MR (CON; 20% CP, 20% fat), (2) 669g DM of a moderately high protein MR (moderate; MOD; 26% CP, 18% fat), or (3) 892g DM of a moderately high protein MR (aggressive; AGG; 26% CP, 18% fat). All calves had ad libitum access to starter and water. Both MR and starter were medicated with decoquinate. During weaning (d 43-49), the morning MR feeding ceased. On d 50, all MR feedings ended; however, starter and water intakes were continuously recorded until d 56. At 5wk of age, urine was collected using urinary catheters for 3d and chromium oxide was administered by bolus at 2g/d for 7d to estimate N efficiency. Calves fed MOD and AGG had similar starter intakes, feed efficiencies, and ADG, with the combined treatments having reduced starter intakes (258 vs. 537g/d), greater ADG (674 vs. 422g/d), and improved feed efficiency (0.57 vs. 0.45 gain:feed) compared with CON calves preweaning. However, DMI and water intake were similar across all treatments. Results from the N utilization phase showed that MOD and AGG treatments had similar but lower N efficiency compared with CON calves (45.5 vs. 52.7%). This could be due to MOD- and AGG-fed calves having greater urine volume and thereby, greater combined urine N output compared with CON calves (17.6 vs. 12.1 g/d). In summary, feeding >0.66kg (DM) from a 26% CP MR increased ADG and improved feed efficiency during the preweaning period but reduced starter intake and lowered N efficiency.

“…This result is in agreement with the studies of Coverdale et al (2004), Franklin et al (2003), and Greenwood et al (1997) who reported no significant difference in BW until wk 5. However, reduced BW gain after weaning has been reported by some researchers (Huber et al, 1984; Anderson et al, 1987; Luchini et al, 1991). Starter intake and growth rate in the post-weaning period were 5.8 kg and 0.45 kg/d, 4.1 kg and 0.65 kg/d, 4.2 kg and 0.77 kg/d, 3.4 kg and 0.75 kg/d for calves in 350 g/d, 500 g/d, 650 g/d, and 800 g/d groups, respectively.…”

To evaluate the effects of feeding four different levels of starter in male Holstein dairy calves, a completely randomized study was conducted, using 28 calves with initial body weight of 40.5±2.4 kg. The animals were fed iso-nitrogenous starter and were weaned when they consumed 350, 500, 650 and 800 g/d of starter for 3 d consecutively. Starter and water were available ad-libitum throughout the experiment. Body weight at pre-weaning (less than 5 wk) and post-weaning (8 wk) was lower in calves that received 350 g/d of starter than in the other treatments (p<0.05). Feed conversion ratio (FCR) was the highest among all treatments in pre-weaning period (p<0.05). Dry matter intake (DMI) at weaning and total DMI was higher in that calves received 800 g/d of starter compared with other treatments (p<0.05). Calves fed 350 and 500 g/d of starter were weaned earlier (p<0.05) and showed lower milk consumption (kg, DM) compared with other treatments whereas no significant difference was observed between calves fed 350 and 500 g/d of starter (p>0.05). Dry matter, organic matter and crude protein digestibilities were lower in calves that received 350 g/d of starter compared with other treatments (p<0.05). No differences were observed in acid detergent and neutral detergent fiber digestibility among all treatments (p>0.05).Treatments had no significant effect on time of starting rumination, respiratory score, and days of drug administration for pneumonia. There were no meaningful differences in feces, fecal odor scores, body temperature, and days of drug administration for diarrhea among all treatments (p>0.05). Total dry matter intake at the end of experiment showed no significant difference among calves fed 600 and 800 g/d of starter, but calves fed 350 and 500 g/d of starter showed more dry matter (DM) intake than calves in the 600 and 800 g/d groups (p<0.05).
