“…When the feed provided to feedlot cattle is altered from a high-forage to a high-concentrate diet, marked changes in the ruminal environment often result (Bevans et al 2005). Consequently, the cattle may suffer from conditions such as ruminal acidosis, damage to the ruminal mucosa, dehydration and even metabolic acidosis (Moya et al 2009;Laskoski et al 2014). Ouyang et al (2014) reported that supplemented niacin can regulate ruminal lactic acid metabolism, promote rumen fermentation and stabilise the ruminal environment.…”

In the present study, the effect of niacin supplementation on the growth performance and nutrient utilisation in Chinese Jinjiang cattle was investigated. A total of 48 finishing male Jinjiang cattle aged 24-30 months, with body weights of 200 ± 15 kg, were randomly divided into four groups. The cattle were fed a finishing diet (concentrate to forage ratio of 80:20). The diets for the control, NA 320 , NA 480 and NA 640 groups were supplemented with 0, 320, 480 or 640 mg/kg of niacin, respectively. The body weight and feed consumption of the 48 cattle were recorded on days 1, 28, and 56 of the experiment. Assessment of feed digestibility was conducted from days 52 to 56 of the study. Blood samples were collected from each animal on day 56. From days 1 to 56 of the study, the results indicated a significant increase in the average daily weight gains (p < .05) and lower feed to gain ratios (p < .05) for the NA 480 and NA 640 groups than for the control group. Furthermore, supplementation with 640 mg/kg niacin increased the apparent digestibility of all nutrients (p < .05), whereas supplementation with 480 mg/kg niacin enhanced the apparent digestibility of crude protein (p < .05). Moreover, supplementation with 480 and 640 mg/kg niacin increased the content of serum nonesterified fatty acids (p < .05). Therefore, it was concluded that supplementation with 640 mg/kg niacin in a high-concentrate diet may be beneficial to growth and nutrient utilisation in Chinese Jinjiang cattle.

“…The SB supplementation in high concentrate diets for lambs resulted in greater ruminal pH and improvement of performance (SANTRA et al, 2003;TRIPATHI et al, 2004). LASKOSKI et al (2014) evaluated SB to avoid metabolic acidosis in sheep subjected to experimental ruminal acidosis and reported that the buffer has a positive effect, reducing its severity. Conversely, GASTALDELLO JR et al (2013) reported no effect of SB supplementation (1% DM) for feedlot lambs fed high grain diets, the authors attributed this lack of effect to the low level of SB used.…”

Intake and apparent nutrient digestibility, ruminal parameters, and nitrogen balance of lambs fed with corn and forage-free diets with sodium bicarbonate

et al. 2023

This study evaluated forage-free diets supplemented with sodium bicarbonate (SB) based on ground flint corn on intake, apparent nutrient digestibility, ruminal parameters, and N balance. Four rumen-cannulatedDorper × Santa Inês lambs, with a body weight of 43.4 ± 0.85 kg (mean ± standard deviation) were used. The experimental design was a 4×4 Latin square. Each experimental period lasted 21 days. Experimental diets were: positive control, a diet without SB containing 400 g/kg DM of soybean hulls (CONT), and three diets based on ground flint corn, containing 10 (10SB), 20 (20SB) or 30 (30SB) g/kg DM of SB. Intake of neutral and acid detergent fiber was greater for CONT (P < 0.01) when compared to SB. Intake and apparent nutrient digestibility of dry and organic matter, ether extract, and crude protein did not differ. Intake (P = 0.01) and digestibility (P < 0.01) of non-fiber carbohydrates were greater for SB diets and neutral detergent fiber digestibility was greater (P = 0.03) for CONT. The total digestible nutrients and metabolizable energy were greater for SB (P = 0.04). Rumen concentrations of acetate (P < 0.01), isobutyrate (P < 0.01), butyrate (P < 0.01), isovalerate (P < 0.01), and total short-chain fatty acids (P < 0.01) were greater for CONT. Ruminal pH showed a quadratic (P = 0.05) response to SB levels, with greater values for 20SB. Sodium bicarbonate was efficient in increasing ruminal pH at the level of 20 g/kg DM without interfering with the intake and apparent nutrient digestibility characteristics.

“…This disease results from an excessive intake of soluble carbohydrates, especially in nonadapted animals, and it may manifest as acute ruminal lactic acidosis (ARLA); subacute ruminal acidosis (SARA), or it may be chronic (BRAUN et al, 1992;LASKOSKI et al, 2014;LETTAT et al, 2010;REIS et al, 2014). Administering a concentrate to animals reduces the dietary fiber content, which decreases rumination and salivary buffering.…”

Clinical evaluation of unadapted sheep submited to sudden intake of melon with high levels of sugar

et al. 2015

This study evaluated the clinical effects of two different amounts of melon, with a high sugar content, suddenly offered to unadapted sheep. Twelve rumem cannulated crossbred 8-months-old sheep , weighing 25 kg each, were used. These sheep had never been fed with food concentrated with sugar or fruits. The animals were kept in collective pens with a basal diet of roughage and then randomly divided into two equal groups. The sheep in the two groups received 25% and 75% of dry matter (DM) of the diet the crushed melon, administered by the rumen cannula. Physical examination and measurement of rumen fluid pH was performed at the following times: 0, 3, 6, 12, 18 and 24 h. The animals of G25% did not present clinical signs despite subacute acidosis expected after administration of the melon. However, in the G75%, sheep developed clinical manifestation indicative of lactic acidosis with rumen fluid pH lower than 5.0 from T6h, but did not present with dehydration. In sheep from G75 %, tachycardia was observed at 3 h and continued until the end of the study; tachypnea was also observed at 3 h, which was caused by increased abdominal circumference. Based on the results obtained, the supplementation of high amounts of melon (75% DM) in the diet is not recommended for sheep, although the use of 25% DM is safe. However, greater amounts of this fruit could be used in the diet of sheep with gradual adaptation to the substrate. utilizados 12 ovinos canulados, mestiços da raça Santa Inês, machos, pesando 25 kg, com oito meses de idade e que nunca haviam recebido rações concentradas, frutas ou raízes. Os animais foram mantidos em baias coletivas com dieta basal composta de volumoso e distribuídos aleatoriamente em dois grupos iguais que receberam, subitamente, quantidades de melão triturado correspondentes a 25 e 75% da matéria seca (MS) da dieta, administradas pela cânula ruminal. Foi realizado exame físico e mensuração do pH do fluido ruminal nos seguintes momentos: zero, 3, 6, 12, 18 e 24 h. Os animais do G25% não manifestaram sintomatologia clínica, apesar da acidose subaguda esperada após a administração de melão. Os animais do G75% desenvolveram quadro clínico indicativo de acidose láctica ruminal, com pH deste fluido inferior a 5,0 a partir do T6h, mas sem apresentar desidratação. Nos ovinos do G75% foi observada taquicardia a partir do momento 3 horas até o final do estudo e discreta taquipnéia no momento 3 horas, causadas pelo aumento da circunferência abdominal. Não se recomenda o oferecimento de altas quantidades de melão (75% da M.S.), porém a quantidade correspondente a 25% da M.S. é segura. Maiores concentrações dessa fruta na dieta podem ser utilizadas desde que se tomem cuidados para a adaptação gradual dos animais ao substrato.
