“…In the case of the NR group, lambs had earlier complement system activation, which was greater compared to the C4 and C8 groups at 1 to 3 days. Despite the fact that colostrum freezing for storage does not affect immunoglobulin concentration in newborn ruminants (Holloway et al, 2002;Argüello et al, 2003), other colostrum components could be affected by the freezing process (Ramírez-Santana et al, 2012). As was described before, the C4 and C8 groups were fed colostrum from a frozen pool that may cause reduction of some complement components present in colostrum.…”

“…Artificially reared lambs received colostrum amount equivalent to 4 g of IgG/kg of BW at birth (C4 group) or 8 g of IgG/kg of BW at birth (C8 group) divided into three meals at 2, 14 and 24 h after birth. Colostrum meals were always thawed and heated at 37°C according to Argüello et al (2003). Colostrum IgG and IgM concentrations (64.37 and 5.61 mg/ml, respectively) were determined using commercial ELISA kits (Bethyl laboratories, Montgomery, TX, USA), using a purified sheep IgG or a purified sheep IgM as the standard curve.…”

The aim of this study was to investigate the BW and immune status of lambs reared under natural conditions or under artificial conditions fed two different colostrum amounts. In this study, 60 lambs were randomly divided into groups according to treatment. Twenty lambs remained with their dams (natural rearing (NR) group). Forty lambs were removed from their dams at birth. Lambs were bottle-fed with a pool of sheep colostrum, receiving either 4 g of IgG/kg of BW at birth (C4 group) or 8 g of IgG/kg of BW at birth (C8 group). The total colostrum amount was equally divided into three meals at 2, 14 and 24 h after birth. After this period, lambs were bottle-fed a commercial milk replacer. Blood plasma sample analysis and BW recordings were carried out before feeding at birth and then at 1, 2, 3, 4, 5 and 20 days after birth. Another blood sample analysis and BW recording was carried out when animals reached 10 kg of BW. During weaning (30 days), sampling was carried out every 5 days. Blood plasma was used to determine the concentrations of IgG and IgM and the complement system activity -total and alternative pathways. The NR group showed greater BW than the C4 and C8 groups during milk feeding period, whereas the C4 and C8 groups had greater BW than the NR group at the end of weaning period. The C8 and NR groups had greater plasma IgG and IgM concentrations than the C4 group during milk feeding period. In addition, C4 and C8 groups showed similar IgG concentrations and greater IgM concentrations than the NR group at the end of the weaning period. Complement system activity was greater in the NR group than in the C4 and C8 groups during the first 3 days after birth. In conclusion, lambs fed amounts of colostrum equivalent to 8 g of IgG/kg of BW showed similar immune variables compared to lambs reared under natural conditions, obtaining a greater BW at the end of the weaning period. Nevertheless, this study shows that not only the colostrum amount but also the management during the milk feeding and weaning period, such as stress produced by dam separation, milk quality and suckling frequency, can affect the final immune status of lambs.Keywords: immune, lamb, colostrum, weaning, artificial rearing ImplicationsColostrum plays a fundamental role in the immunization of newborn ruminants. Artificial rearing is a common method used in dairy farms, increasing the amount of milk for processing. The aim of this study was to feed newborn lambs colostrum with two different IgG concentrations and to compare these animals to natural dam fed lambs. This study showed that administration of 8 g of immunoglobulin g/kg BW at birth, equally divided into three colostrum meals (2, 14 and 26 h), achieved higher circulating immunoglobulin G concentration when compared to the natural rearing treatment, although both artificial rearing groups decreased BW after birth. IntroductionThe relationship between colostrum and the survival of newborn ruminants has been long characterized (Argüello et al., 2004;Castro et al., 2011;Abdou et al., 2014)...

“…O armazenamento do colostro pode ser na forma refrigerada ou congelada (Argüello et al, 2003), quando se deseja preservar as imunoglobulinas (Borges et al, 2001), ou fermentada, quando se quer conservar o valor nutricional. Essa última opção é mais utilizada para grandes volumes (Morril, 1992;Matos, 1996).…”

Utilizaram-se 40 bezerros Holandês × Zebu distribuídos em oito tratamentos (T): leite integral (1); leite integral com óleo de soja (2); leite integral e zeranol (3); leite integral com óleo de soja e zeranol (4); colostro fermentado (5); colostro fermentado com óleo de soja (6); colostro fermentado e zeranol (7); e colostro fermentado com óleo de soja e zeranol (8) com o objetivo de avaliar o consumo de alimentos, o crescimento e a conversão alimentar de animais entre o 15º e o 60º dia de vida. Diariamente, foram fornecidos 1,5kg de concentrado contendo 23% de proteína bruta, feno de tifton (Cynodon dactylon) à vontade e três litros de leite ou colostro fermentado. O colostro fermentado proporcionou melhores resultados de peso corporal e ganho de peso quando comparado ao leite integral, mas semelhantes aos resultados com zeranol. Também promoveu maior ingestão de matéria seca em relação ao leite integral, o que resultou em desempenhos semelhantes para esses dois tipos de alimento. Não houve diferenças entre os tratamentos quanto aos componentes não-integrantes da carcaça. O tratamento com leite e zeranol resultou em maior peso de carne industrial e o com óleo de soja aumentou a proporção de gordura interna. O colostro fermentado é uma boa opção para a recria de machos leiteiros e o efeito do zeranol sobre o ganho de peso é dependente da dieta dos animais.

“…Esses produtos contêm características nutricionais superiores às do leite integral, entretanto não apresentam valor comercial (Modesto et al, 2002). Dessa foram representam alternativa viável e racional como sucedâneo do leite na cria de bezerros (Arguello et al, 2003;Ribeiro et al, 2001) O acondicionamento e armazenamento, anaeróbico do colostro e do leite de transição excedente, em garrafas de plástico de politereftalato de etilenotipo (PET) é conhecido como silagem de colostro, que pode ser estocada em temperatura ambiente até seis meses (Saalfeld et al 2013). Entretanto, com relação ao desempenho de bezerros, os resultados ainda são controversos.…”

RESUMOO objetivo com esta pesquisa foi avaliar as características ruminais e a microbiota gastrointestinal de bezerros leiteiros em diferentes sistemas de aleitamento com silagem de leite de transição. Foram utilizados 18 bezerros Holandeses, entre 6 e 59 dias de idade, distribuídos em delineamento inteiramente casualizado. No tratamento convencional, foram fornecidos 4 L de leite por dia. No segundo e terceiro tratamentos, foram fornecidos 2 L de silagem de leite de transição misturados a 2 L de água ou leite, respectivamente. Aos 60 dias de idade, após eutanásia, foram coletados aproximadamente 15 mL do conteúdo do rúmen, abomaso e do intestino delgado e 10 g de fezes. Os sistemas de aleitamento não influenciaram as características de cor, odor e viscosidade do líquido ruminal. O pH e a quantificação de Enterobacteriaceae, fungos micelianos e leveduriformes nos diferentes sítios do trato digestório não foram influenciados pelos sistemas de aleitamento avaliados. Aspergillus spp. foi o fungo micieliano mais frequente em ambos tratamentos. Os aleitamentos com silagem de leite de transição, em água ou em leite, não influenciaram as características físico-químicas e microbiológicas avaliadas, corroborando com os estudos que indicam que esse produto poderia ser utilizado como sucedâneo lácteo na criação de bezerros leiteiros.Palavras-chave: fermentação lática, microbiota ruminal, sistemas de aleitamento, sucedâneo Physicochemical and microbiological characterization of ruminal fluid and gastrointestinal contents of calves fed with transition milk silage ABSTRACTThe objective was to evaluate the ruminal characteristics and gastrointestinal microbiota of dairy calves in different milk feeding systems. In an entirely randomized design, 18 Holstein calves at 6 to 59 day of age were used randomly allotted. In the conventional treatment were provided 4 L of milk daily. In the second and third treatments, 2 L of transition milk fermented were administered to 2 L of water or 2 L of milk, respectively. At 60 days of age, it was collected approximately 15 mL of the contents of the tract digestive (rumen, abomasum, and small intestine) and feces after necropsy. The different systems of feeding did not influence the color characteristics, odor and viscosity of the ruminal juice. The pH and quantification of Enterobacteriaceae, mycelium fungi and yeast fungi did not show significant difference between treatments for the different sites studied. Aspergillus spp. was the mycelia fungi most frequent between isolates from gastrointestinal tract for both milk systems. The treatments with transition milk silage, in water or milk, did not influence the physicochemical and microbiological characteristics evaluated, corroborating studies indicate this product can be used as milk replacer for the dairy calves.
