“…LPS challenge negatively affects SD rat digestive function . Recently, it has been reported that the LPS challenge activated immune responses and negatively impacted the growth performance of domestic animals (1, 25). In present studies, the growth rate of SD rats was obviously inhibited after multiple small dose LPS injections so that dysplasia appeared in the rats.…”

IntroductionThe study was designed to investigate the effects of repeated lipopolysaccharide (LPS) treatment on growth performance, lymphoid organ indexes, and blood cells in Sprague-Dawley rats.Material and MethodsForty healthy weaned Sprague-Dawley rats were randomly equally divided into LPS and control groups. Each rat in the LPS group was injected via the caudal vein with LPS (100 μg/kg b.w.) for 10 days, and the control group was treated with an equal volume of normal saline. On the 1st, 4th, 7th, and 10th days, growth performance, lymphoid organ indexes, and blood cells were evaluated in five necropsied rats.ResultsWhen rats were treated 3–10 times with LPS, their body weight and average daily gains increased more slowly than in the control group (P < 0.05). Repeated LPS treatment significantly increased spleen weight and the ratio of spleen to body weight (P < 0.05). White blood cells, neutrophils, and neutrophil percentage increased (P < 0.05) remarkably, but lymphocyte percentage, haemoglobin, and blood platelet counts decreased significantly (P < 0.05).ConclusionLPS treatment obviously suppresses growth and promotes peripheral immune organ proliferation. It is indicated that host protective mechanism can be activated by multiple small doses of LPS and prevents organs from further damage during stress status.

“…To create a well-herd composition, the heifers to be included into the herd should be available for high-yield and they should be well-developed to present their potential, in other words, they should reflect these characteristics on phenotypes. Such a case can only be possible with well-nutrition and care of calves from the first day of their birth on (Kumar et al, 2017;Zhang et al, 2017).…”

The present study was conducted to assess the effects of pre-weaning probiotic treatments on growth performance of male Holstein calves. For experimental treatments, 20 male calves were divided into 2 groups as of control and treatment group. Control group calves were supplied with fresh milk daily in two meals without any growth promoting supplement. Together with fresh milk supply, treatment group calves were supplied with additional 2 g probiotics to their morning meal. Throughout 56-day milk-feeding period, live weights (LW) and feed consumptions (FC) of the calves were determined. As compared to the control group, probiotic-supplemented calves had 5.25% higher weaning live weight and 11.4% higher daily live weight gain (P less than 0.05). Probiotic-supplemented calves consumed 2% more feed than the control calves (P>0.05) and had 9.52% better feed conversion ratio than the control group calves (P less than 0.05). Probiotic supplementation did not affect blood biochemical parameters significantly (P less than 0.05), except ALT, triglyceride and iron levels (P less than 0.05). It was concluded that probiotic supplementation during milk-feeding period improved growth performance of experimental Holstein calves.

“…Increasing the body temperature of calves that experience HS [11,12,13] can increase intestinal epithelial permeability responses to enteric pathogens. Additionally, previous studies [28,29] have reported that calves exposed to LPS ( E . coli O55:B5) show increased rectal temperature and body temperature compared to saline-infused calves.…”

The objective of this study was to determine the effects of Saccharomyces boulardii CNCM I-1079 (SB) as a feed additive on performance, diarrhea frequency, rectal temperature, heart rate, water consumption, cortisol level, and fecal bacteria population in Holstein calves (28 ± 1.6 days of age, body weight of 45.6 ± 1.44 kg, n = 16) under thermal neutral (TN) and heat stress (HS) conditions. During the TN period for 21 days (d 1 to 21), calves receiving SB showed quadratic or linear effects compared to the control group, showing higher dry matter intake (DMI, p = 0.002), and water consumption (p = 0.007) but lower frequency of fecal diarrhea (p = 0.008), rectal temperature (p < 0.001), heart rate (p < 0.001), and fecal microbiota at 21 day (Escherichia coli, p = 0.025; Enterobacteriaceae, p = 0.041). Meanwhile, calves exposed to HS for 7 days (d 22 to 28) receiving SB showed quadratic or linear effects compared to the control group, showing higher DMI (p = 0.002) but lower water consumption (p = 0.023), rectal temperature (p = 0.026), and cortisol level (p = 0.014). Our results suggest that live SB is useful in the livestock industry as an alternative to conventional medication (especially in times of suspected health problems) that can be added to milk replacer for young dairy calves experiencing HS.
