“…Our results are similar to those obtained by others who showed beneficial effects of probiotics on performance of rearing calves (Abe et al, 1995;Morrill et al, 1995;Cruywagen et al, 1996;Donovan et al, 2002;Timmerman et al, 2005), although in some studies no effect of probiotics was observed (Morrill et al, 1977;Jenny et al, 1991;Nakanishi et al, 1993;Abu-Tarboush et al, 1996). The reasons for such a discrepancy in opinions may result from the health status of the maternal herd, experimental conditions and management systems.…”

“…This positive effect was particularly apparent in later stages of the trial (weeks 3-4), it means in older calves (from 5 th week of age). Similar effect of probiotics on higher solid feed intake by calves was observed by others (Schwab et al, 1980;Ruppert et al, 1994;Abe et al, 1995), although in some experiments no effect (Jenny et al, 1991;Cruywagen et al, 1996;Abu-Tarboush et al, 1996;Donovan et al, 2002) or even negative effect (Morrill et al, 1977) was observed.

The aim of a study was to determine the efficacy of the microbial feed additive containing spores of Bacillus licheniformis and Bacillus subtilis (BioPlus 2B ® ) on performance and health status of rearing calves. Sixty four female Holstein calves, aged on average 16.7 ± 4.5 days, were randomly assigned into two groups of 32 animals: control (C) and BioPlus 2B ® (BP). Milk replacer (MR) and starter mixture (SM) fed to BP group contained 1.32 × 10 9 (±3.2%) and 1.13 × 10 9 (±11.5%) spores of Bacilli strains, respectively. Each calf was fed with 2.25 l of MR two times a day for eight weeks, up to the age of approximately 10 weeks. Starter diet (SD) offered to calves consisted of SM and whole maize grain, which were mixed in ratio 50:50 (wt/wt). Intake of MR was equal in both groups, but SD intake was higher in the whole experiment in the BP group (1075 vs 951 g/d; P<0.01). The BP calves grew faster than C ones in the whole trial (P=0.05), but especially in weeks 3-4 (P<0.05). At the end of the trial the BP calves were about 2.9 kg heavier than the C ones (P<0.001). Feed efficiency, calculated as consumption of ME (MJ) or crude protein (g), was not different between treatments. There were also no differences in the health status and faecal score between treatments. The results of this study suggest the beneficial effect of microbial feed additive containing spores of Bacillus licheniformis and Bacillus subtilis for rearing calves.

“…Rates of BW gain of calves during the initial 28 d of life are often limited to <500 g/d by feeding management, pathogen exposure, and environmental factors (29). Consequently, use of antibiotics and other feed additives to reduce the effects of pathogen exposure have been incorporated into CMR formulations (20,24). Weekly BW gains ( Figure 1) were unaffected by treatment and indicated that BW gains during the first wk of the study were minimal.…”

An alternative protein ingredient based on spraydried, hydrolyzed red blood cells was evaluated in calf milk replacers. Two experiments were conduced to determine the value of the ingredient on intake, growth, and feed efficiency in dairy calves. In experiment 1, Holstein bull calves (n = 120) were fed calf milk replacer containing 0, 11, 22, or 43% of crude protein as spray dried hydrolyzed red blood cells. Calves were fed 454 g/d of experimental milk replacer reconstituted to 12% dry matter plus a conventional calf starter for 28 d. Body weight gain, intake of milk replacer and calf starter, feed efficiency, fecal scores, and days scouring were unaffected by source of protein. In experiment 2, Holstein calves (n = 69) at the University of Minnesota, Crookston and Waseca were fed milk replacer containing 0, 22, or 43% of crude protein as spray dried hydrolyzed red blood cells. Calves were fed 454 g/d of experimental milk replacer reconstituted to 12% dry matter plus a conventional calf starter containing 0 or 25% alfalfa meal for 35 d. No calves died during the study. Body weight gain, feed efficiency, intake of calf starter and milk replacer, fecal scores, and days scouring were unaffected by increasing hydrolyzed red blood cells in milk replacer. Similar performance of all calves indicated that spray dried hydrolyzed red blood cells can replace up to 43% of crude protein from whey protein concentrate without detrimental effects on animal performance. 788Abbreviation key: CMR = calf milk replacer, CON = CMR containing no SDHRBC, CS = calf starter, HIGH = CMR containing SDHRBC at 43% of CP, LOW = CMR containing SDHRBC at 11% of CP, MED = CMR containing SDHRBC at 22% of CP, SDHRBC = spray-dried hydrolyzed red blood cells, SDRBC = spray-dried red blood cells.

Alguns autores observaram melhores desempenhos de bezerros recebendo probiótico (SCHWAB et al, 1980;ROSELL, 1987;ROACH et al, 1989;e ABE et al, 1995), enquanto outros não verificaram diferença entre bezerros tratados e os do grupo controle (MORRILL et al, 1977;ELLINGER et al, 1978;JENNY et al, 1991;MORRILL et al, 1992;HIGGINBOTHAM e BATH, 1993;e ABU et al, 1996). O modo de administração e a qualidade do produto, além das condições do ambiente onde os ensaios são realizados, sem dúvida, podem justificar a diversidade dos resultados obtidos com a utilização de probióticos para bezerros.…”

RESUMO -O objetivo deste trabalho foi verificar o efeito do fornecimento da estirpe LT 516 de Lactobacillus acidophilus, junto ao leite, sobre o desempenho de bezerros de rebanhos leiteiros, do nascimento aos 56 dias de idade. Trinta e seis bezerros recém-nascidos foram distribuídos em blocos ao acaso de acordo com o sexo, grau de sangue e peso ao nascer. O fornecimento diário de um concentrado com células viáveis (1,9 x 10 10 UFC/anim) de Lactobacillus acidophilus (LT 516), do nascimento aos 56 dias de idade (Tratamento 1), o fornecimento diário do mesmo concentrado do nascimento aos 10 dias de idade (Tratamento 2) e o não-fornecimento de Lactobacillus acidophilus (Tratamento 3) foram estudados. Os animais foram alimentados com 4 L de leite integral/anim•d e, a partir da segunda semana de idade, concentrado inicial e capim-elefante (Pennisetum purpureum Schum) picado, à vontade. Não houve diferenças entre tratamentos nos consumos e nas digestibilidades aparentes da matéria seca e proteína bruta, no ganho de peso, na contagem de hematócritos, hemoglobina, glóbulos vermelhos e hemoglobina globular média, na concentração de hemoglobina globular média, no volume globular médio e na contagem global de leucócitos, na capacidade absortiva do intestino (estimada pelo teste de xilose), no pH da digesta do intestino delgado e no número de lactobacilos facultativos e coliformes totais nas fezes. O fornecimento de Lactobacillus acidophilus (LT 516) reduziu a ocorrência de diarréias, sem influir no odor e na consistência das fezes. Os animais que receberam probiótico nos primeiros 10 dias apresentaram maior número de lactobacilos facultativos no intestino delgado. O número de coliformes totais no intestino delgado foi maior nos animais controle e menor nos que receberam probiótico nos primeiros 56 dias. Palavras-chave: bezerros, diarréia, Lactobacillus acidophilus, probiótico Effect of One Strain of Lactobacillus acidophilus (LT 516) as Probiotic for CalvesABSTRACT -The objective of this work was to verify the effect of the supply LT 516 strain of Lactobacillus acidophilus, adjoining to the milk, on dairy calves performance from birth to 56 days of age. Thirty-six newborn calves were allotted to a randomized blocks grouped by sex, breed and birth weight. The daily supply of a concentrate with viable cell (1,9 x 10 10 UFC/anim) of Lactobacillus acidophilus (LT 516), from birth to 56 days of age (Treatment 1); the daily supply of the same concentrate from birth to 10 days of age (Treatment 2) and no supply of Lactobacillus acidophilus (Treatment 3) were studied. Calves were fed 4 L of whole milk/anim•d, and from the second week of age, a starter concentrate and ad libitum chopped elephant grass (Pennisetum purpureum Schum). There were no differences among treatments on dry matter and crude protein intakes and apparent digestibility, weight gain, hematocrit, hemoglobin, red globules count, average globular hemoglobin, average globular hemoglobin concentration, average globular volume and leukocytes global count, on the absorpt...
