A study was conducted on 24 fifteen day old crossbred calves that were divided into 4 groups of 6 calves each. The calves were fed different dietary treatments viz T 0 (control group) -basal diet, T 1 (probiotic group) -basal diet + Lactobacillus acidophilus @ 1 g/calf/day (2 x 10 10 cfu/ g), T 2 (prebiotic group) -basal diet + Mannan oligosaccharide (MOS) @ 4 g per calf/day and T 3 (synbiotic group) basal diet + Lactobacillus acidophilus @ 0.5 gm (2 x 10 10 cfu/ g) + 2 g MOS per calf/day respectively for a period of 90 days. Blood samples were taken at monthly interval and serum was separated to estimate different biochemical parameters. The results of study indicated that probiotic (Lactobacillus acidophilus), prebiotic (MOS) and synbiotic supplementation were effective in reduction of serum cholesterol and triglycerides at 60 th and 90 th day. Serum creatinine, glucose, urea and bilirubin were unaffected by dietary supplementation of probiotic, prebiotic (MOS) and synbiotic. There was no effect of T 1, T 2 and T 3 supplementation on Serum enzymes, Aspartate aminotransferase (AST) and Alanine Amino Transferase (ALT).

“…The result indicated that Mattha helps in reduction of internal parasite in Murrah buffalo calves which might be due to clearance of microvilli in small intestines. There was no effect of feeding probiotics on EPG of young calves (Frizzo et al, 2010).Therewas significant reduction of EPG in faeces of cannines supplemented with probiotics (Coêlho et al, 2013).…”

Therapeutic effect of traditionally prepared Mattha/ buttermilk and Chedu/ ghee residue on parasitic load and body coat of Murrah buffalo calves

As per Indian system of medicine (Ayurveda), Mattha is helpful in maintaining gut health, mitigation of kappa and vata and preventing obesity. The present study was undertaken to evaluate the effect of mattha and chedu on parasitic load of Murrah calves. 1-year-old twenty growing buffalo calves with approximately similar weight were selected and divided into four groups having five animals in each group. Following treatments were offered: -T 0 (control), T 1 (application of Chedu on their body), T 2 (Administration of Mattha @ 2% of body weight with salt @ 0.5% of Mattha), T 3 (Administration of Mattha and application of Chedu). Fecal samples were collected directly from rectum or freshly voided feces in sterilized poly bags, twice a month from buffalo calves to check the internal parasitic load. Number of ticks, were counted in most heavily infested area i.e. inguinal region, brisket region, neck region, tail fold, and base of the ear after every 4 days. From 30 th day to 90 th day there was a significant difference observed in terms of eggs per gram (EPG) in treatment groups T 2 and T 3 with respect to control group indicating lower parasitic load in treated groups. Application of chedu in T 1 and T 3 group resulted in gradual decrease of tick load which depicts therapeutic value of chedu and combination of mathha and chedu on ticks. Also chedu treated groups showed increased lusture of body coat which is desirable in terms of aesthetic value and wellbeing of buffalo calves.

“…Similarly, Kowalski et al (2009) found that supplementing with Bacillus subtilis and Bacillus licheniformis in milk replacer and pellets fed to pre-weaned calves improved their dry matter intake (DMI) and DWG. By contrast, no benefits in health status or growth performance were recorded in pre-weaned calves supplemented with a probiotic mix of Lactobacillus casei, Lactobacillus salivarius and Pediococcus acidilactici (Frizzo et al 2010a) Recently, Bacillus probiotics have been promoted as being relatively easier to apply to diets due to their spore-forming ability, which allows them to survive through feed processing and storage phases as well as in the acidic environment of the digestive tract.…”

Response of ruminant health and growth to the probiotic Bacillus amyloliquefaciens

Le¹

Probiotics are widely used to restore and maintain normal digestive flora to reduce metabolic disorders and improve health and productivity, especially in simple-stomached animals but less so in ruminants. Bacillus amyloliquefaciens strain H57 (H57) is a novel probiotic that has previously been shown in a pilot study to reduce the risk of hay spoilage and, over a relatively short term of a few weeks, improved dry matter intake (DMI) and the efficiency of nitrogen utilization in pregnant ewes fed the treated hay. The aim of the current study was to evaluate H57 over much longer periods of time than the pilot study, to confirm health and performance responses such as daily weight gain (DWG) at key stress periods in a ruminant's life. The effect of H57 on rumen fermentation, digestibility and concentration of metabolic hormones were also investigated to better understand the actions of H57 in ruminants.The first experiment (Chapter 2) investigated the effect of H57 during the transition from pregnancy to lactation when ruminants undergo a rapid change in metabolic demand.Twenty-four pregnant ewes were individually fed pellets, based on palm kernel meal, to meet their requirements for pregnancy and to gain 70g/d. They were then fed an ad libitum mixture of lucerne and oaten hay during lactation. The H57 improved DMI and DWG in late pregnancy and consequent lamb growth in early lactation. During late pregnancy, the ewes fed H57 ate 16.6% more pellets, retained 45% more nitrogen between 39 and 26 days prior to parturition, and were 17% heavier by parturition. H57 inoculated pellets did not change the digestibility of dietary energy or protein but did modify rumen fermentation toward an increase in the concentration of butyrate and valerate.In the second experiment (Chapter 3), the effect of H57 was investigated around the weaning process, another commonly stressful period in ruminant life. Twenty-four male or female calves were allocated into two groups, and between 4 and 12 weeks of age were individually offered 6 L/d of whole milk and ad libitum starter pellets impregnated with or without H57. Similar to the first experiment, calves fed H57 grew faster, tended to consume more pellets and were 14% more feed efficient compared to the Control calves. The duration of diarrhoea was 2 days less in the H57-fed calves compared to the Control calves. The H57-fed calves also weaned 9 days earlier and were 15.8% heavier at week 19. H57 also showed potential to stimulate rumen development by increasing plasma betahydroxybutyrate, which is an indicator of rumen development in young ruminants, and appeared to improve immunity by increasing the concentration of plasma globulin.iii Given the success of H57 in reducing the weaning age and incidence of diarrhoea in the dairy calves in the second experiment, it was considered there could be additional benefits if the H57 is added at the primary colonization time of the GIT microbiome, that is, as close to parturition as possible. Therefore in the third experiment (Chapter 4), ...
