“…Effect of calf nutrition on performance outlined by Drackley (2008) have only been recorded in a limited number of studies such as Diaz et al (2001) and Bork et al (2000) with both studies feeding to percentage body weight resulting in MR DM intakes approaching 2.5 kg/day (Diaz et al, 2001). Studies reporting growth rates of approximately 0.7 to 0.9 kg/day are relatively numerous in number but are with calves offered whole milk (Bar-Peled et al, 1997;Jasper and Weary, 2002;Shamay et al, 2005) or with calves that are 2 weeks old at least before commencement of the study (Brown et al, 2005a;Fallon et al, 2005;Bartlett et al, 2006).…”

“…For 85% of properties with daily milk production levels below 200 L, some type of roughage <200 201 to 700 >700 All herds source is offered to calves; this also occurs for 74% of properties with daily milk production levels above 700 L. In other words, the supply of roughage during the liquidfeeding phase is predominant in the majority of properties. According to Drackley (2008), the replacement of milk with a solid diet (grains and forages) is a factor that contributes to the reduction of mortality and favors an increase in the body weight gain of calves. However, studies have shown that although the roughage intake during the milk-feeding phase for calves favors the rumen physical development (Hill et al, 2008), this slows the rumen papillae growth (Khan et al, 2011) due to the change in the fermentation profile (Sakata and Tamate, 1978).…”

“…Segundo Silper et al (2014), o consumo médio no primeiro mês de vida de bezerros foi inferior no grupo que recebeu 4 litros de leite/dia em relação ao grupo em que foi oferecido 6 litros/dia. O volume tradicionalmente utilizado, equivalente a 10% do peso do bezerro, fornece nutrientes apenas para mantença e ganho de peso de no máximo 300g/dia em condições termoneutras (Drackley 2008), sendo, portanto, insuficientes para ganhos esperados de 600-700g/dia nas criações intensivas de bezerros em condições climáticas, na maioria dos casos, fora da zona de conforto. É interessante observar que mesmo durante a diarreia, os bezerros aos quais era oferecido maior volume de sucedâneo, consumiram maior quantidade, o que pode influenciar positivamente na correção do equilíbrio ácido base e de eletrólitos nestes animais.…”

“…De acordo com Drackley (2008) existem evidências de que bezerros com dietas para crescimento acelerado são mais resistentes à diarreia bem como a doenças respirató-rias. Além disso, foi observado que aqueles animais quando apresentam diarreia, tendem a recuperar-se mais rapidamente com menor impacto sobre a taxa de crescimento durante a doença.…”
