The Effects of Probiotics Supplementation on Milk Yield and Composition of Lactating Dairy Cows
The Journal of Phytopharmacology
The effects of microbials dietary supplements on performances and health of the animals, in recent is becoming very critical. Consequently, direct-feds microbials (DFM), is an area of interest of several authors, since last few decades. The probiotics usually, used as DFM for animals are lactic acid bacteria; lactobacillus, streptococci, bifidobacterial, enterococcus and anaerobic fungi species; saccharomyces and aspergillus. Normally, the mechanisms of action of DFM, are modulation of microflora balance in gastrointestinal tract and improvements in digestion and nutrients absorption, sustaining the health of the animals (i.e., through competitive exclusion, secretion of the substances that inhibit the growth or kill and altering gene expression of pathogenic agents) and stimulates the immunity of the animals. Generally, though the effects of host species, types of diet, animal physiological conditions, dosage of probiotics or strain, time of probiotic supplementation and variant strains used, are amongst important factors to be considered, DFM often plays an important role in improvements of milk yield and composition of lactating dairy cows. The DFM of Propionibacterium, Saccharomyces cerevisiae, Lactocbacillus acidophilis, the mixture of yeast products and Enterococcus and combination of L. ecidophilus, L. casei and Enterococcus faecium to dairy cows, significantly improves milk yield and well as the composition. Therefore, DFM, is one of the promising areas of ruminant's nutrition in general or dairy cows in specific, not only because of its nutritional and health benefits to animals, but also due to its negligible residual effects to the animal and animal products.
Probiotics and Dairy Cattle Performance: A Review
2014
The most commonly used probiotics in adult ruminants are Aspergillus oryzae and/or Saccharomyces cerevisiae (SC). Yeast culture was shown to modify ruminal fermentation, increase the numbers of ruminal bacteria and stimulate their growth and to increase milk production in early-lactation cows. Such changes were generally associated with increased digestibility of dietary fibre which could lead to higher dry matter intake or animal performance, or both. Supplementing calves with Lactobacillus and Streptococcus decreased the incidence of diarrhoea. Yeast culture addition increased the feed intake and also significantly increased the DM intake by 1.2 to 1.6 kg/day with a higher milk production. Yeast culture supplements did not have equal beneficial effects with all types of diets, and it is currently not possible to define the dietary conditions that provide optimum response to yeast culture supplementation. Research on the effect of bacterial probiotics on milk yield and composition has been very limited. In general, an increase in the order of 0.75 to 2 kg milk/day was reported, although the effect on feed intake and milk composition has been more variable. There should be systematic study to select promising DFM which are effective in different Indian dairy animals under different agro-climatic zones.
Effect Of Additional Probiotic In Cattle Feed On Cattle's Consumption And Growth Rate
International Journal of Science, Technology & Management
This study aimed to determine the level of feed consumption, weight gain of cattle, and to calculate the population of lactic acid bacteria (LAB) and pathogenic bacteria Escherichia coli and Salmonella in cattle feces in order to determine the effect of giving probiotics on the digestive system of cattle. The research object used was 10 bali cattle with a weight of about 90-120 kg. The data in this study were analyzed by experimental design using analysis of variance to determine the effect of giving probiotics to cattle feed on cattle weight gain. The treatment in question includes G0 with treatment in the form of feeding with a composition of 60% forage, 15% palm cake, 25% cassava, and 100 ml molasses. Meanwhile, G1 was treated with the same feed as G0, but added with 100 ml of probiotic Probio_FM. Based on the results of the study, it is known that probiotics given to cattle feed showed no significant effect on the level of feed consumption and body weight of cattle where cattle ...
On the use of probiotics to improve dairy cattle health and productivity
Microbiology Australia
Probiotics are genetically identifiable, live microorganisms that when administered in adequate amounts, confer appropriately sized health benefit (e.g. correcting dysbiosis, immunomodulatory effect) on a target host. In cattle, probiotics have shown promising results and long-term benefits in productivity when used on animals under stress. The health and production benefits of probiotics were attributed to improvement in fermentation in rumen and intestine, the stabilisation of rumen pH, and improvements in the intestinal barriers. In the bovine udder, a dysbiosis of the commensal intramammary microbiota and the presence of mastitis causing-bacteria has been linked to increased intramammary infections. Probiotic bacteria capable of biofilm formation inside the udder either serve as a barrier against pathogens or disrupt and replace biofilms formed by pathogens. Over the past two decades, several types of probiotics have been used as feed additives; however, the effect of probiotic ...

A trial was conducted on twelve (12) crossbred lactating cows to compare the effects of sodium bicarbonate (bicarb), probiotics and their combination on milk yield, milk composition and dung score. The cows were grouped in to four (4) with three (3) cows in each treatment group, they were fed according to treatment group viz: T0 compounded feed (control), T1 compounded feed + 120g sodium bicarbonate, T2 compounded feed + 10g probiotics and T3 compounded feed + 100g sodium bicarbonate + 5g probiotics. The experiment lasted for a period of 21 days including 10 days adaptation period. The data were statistically analyzed, mean fat percent was significantly (p>0.05) on T1 than T0 (control) followed by T3 and T2 with least on T0. Milk yield and lactose were also significantly increased (p>0.05) by inclusion of probiotics, interaction of probiotics + bicarb. However, milk acidity, protein percent, SNF and CLR was not significantly influenced by test ingredient. The results revealed effectiveness of bicarb to increased fat percent while probiotics increased milk yield and lactose content. Cows dung was also observed under consistency method; Score 2 was observed on T2 while score 3 on T0, T1 and T3. By hand feeling method, score 1 was observed on T2 while score 3 on T0, T1and T3 being equal. The results indicated the effectiveness of probiotics up 10g support higher digestion and microbial performance in the rumen environ compared to other treatment groups.

The blood profile, nutritional-metabolic status, and growth performance of cattle receiving probiotic lactobacilli for 105 days from entry to a feedlot system were evaluated. The trial involved 60 Brangus/Braford castrated steers. They were randomly allocated in pens (n = 15/treatment) and in-feed supplemented with different probiotic suspensions (107–108 CFU/mL/day). The suspensions consisted of (A) Lactobacillus acidophilus CRL2074, (B) Limosilactobacillus fermentum CRL2085, or (C) multistrain CRL2074 + CRL2085 + Limosilactobacillus mucosae CRL2069 formulations, against the control group. Individual samples were taken from each animal thrice throughout the assay (0, 45, and 105 days). Analysis of clinical parameters showed optimal animal body condition and sensorium state. Isolated nasal discharges and the absence of diarrhea were observed at 105 days in the group administered with multistrain and Lim. fermentum CRL2085 probiotics. An increasing trend was observed in cattle growth throughout the trial, which was calculated based on the height at the withers and the thoracic diameter. Weight increase and daily weight gain (1.31 ± 0.12 kg and 1.21 ± 0.21 kg/day, respectively) were maximum for cattle supplied with CRL2085 and multistrain probiotics. Blood and serum parameters were within referential ranges for the control and probiotics-supplemented groups; however, mean values of hematocrit were higher, while the serum glucose, lipid profile, and C-reactive protein values were lower in all the groups. In addition, the multistrain probiotic formulation exhibited higher numbers of cultivable lactic acid bacteria and a slight decrease in the number of enterobacteria in feces at the end of the trial. Therefore, there is great potential for multistrain probiotic formulation to improve the overall performance of feedlot beef cattle.
Influence of yeast, probiotics and enzymes in rations on dairy cows performances during transition
Biotehnologija u stocarstvu, 2008
The main goal of this paper was to investigate the influence of some additives included into high yielding dairy cows rations to overcome the problems in early lactation. These substances directly affect the productive performances of dairy cows as well as udder health. The commercial name of investigated preparation is 'YEASTURE' and it is composed of live yeast cultures selected from three strains Saccharomyces cerevisisiae in combination with probiotic bacteria and enzymes (Lactobacillus casei, Streptococcus faecium, Aspergillus oryzae, Lactobacillus acidophilus, 1,3-b and 1,6 D-Glucan, hemicellulase, Protease, Cellulase, Alpha amylase) which have the ability to modify the fermentation in rumen stimulating the development of ruminal bacteria and increasing the fibre digestion. Effects of this preparation have been investigated on 60 Holstein-Friesian cows divided into two groups. The diets were identical, and trial group received also 10 g of preparation Yeasture daily.

A trial was conducted on Twelve (12) Holstein frisian crossbred lactating cows to compare the effects of sodium bicarnate (bicarb) multi-strain probiotics (probiotics) and their interaction on milk yield and milk composition. The cows were grouped in to four (4) with three (3) cows in each treatment group. They were fed according to treatment group viz: T0 compounded feed (control), T1 compounded feed + 120g sodium bicarbonate, T2 compounded feed + 10g probiotics and T3 compounded feed + 100g sodium bicarbonate + 5g probiotics. The experiment lasted for a period of 21 days including 10 days adaptation period. Data were statistically analyzed, mean fat percent was significantly (p>0.05) on T1 than T0 followed by T3 and T2. Milk yield and lactose were also significantly increased (p>0.05) by inclusion of probiotics, interaction of probiotics + bicarb than control group. However, milk acidity, protein percent, SNF and CLR was not significantly influenced by test ingredient. The results indicate interaction of bicarb + probiotics did not have any unique influence on milk yield or its composition as compared to individual test ingredients in different treatment. Introduction It is well known that the amount of milk produced is highly influenced by the amount and quality of the feed given to the cow. It is also possible to influence milk yield and its composition through feeding. An unbalanced diet increases the risk of metabolic disturbances and weight loss, which have a negative effect on milk yield and its composition. In order to achieved the desired goals, nutrient density must be elevated through increased grain proportions providing necessary energy. High yielding dairy cows received substantial amount of concentrate containing a high proportion of starch in their diets. As the proportion of grain in the diet increases, rumen pH, rumen acetate:propionate ratio and milk fat percentage decreases. If rumen pH is not optimal, dry matter intake decrease, acidosis can cause health problems, and microbial yield of protein and energy decreases (Waje et al., 2010). According to Mertz et al. (2009) the use of feed additives such as (sodium bicarbonate and probiotics) will be helpful in maintaining optimum rumen environment, improve growth and performance of microbes which have beneficial effects on health, growth, production and performance to the host animal. Sodium bicarbonate is used to treat acid ingestion and use to treat metabolic acidosis also used as a buffering agent for the rumen. Sodium bicarbonate is added to the diet to replace endogenous deficiencies in saliva production, which can occur when cows consume a high grain diet. Mertz, et al. (2009) reported that rumen pH decreases when cows in high producing herds are fed highly fermentable carbohydrates, in transition dairy cows, in cows in peak lactation with high dry matter intake, and in cows at peak milk production. Acid neutralizing capacity can vary significantly with different physical and chemical characteristics of dietary buffers and alkalizing agents. Ondarza, B (2006) [15] found that sodium bicarbonate supplementation maintained stable rumen pH over longer period of time; as well she found improved milk production and milk fat. However, the benefits from sodium bicarbonate and other buffers/alkalis were most beneficial in high grain diets and early lactating cows. Probiotics is whole food based supplement of live microorganisms, which benefits the host animal by improving its intestinal microbial balance. Typically, they consist mostly of a combination of fungi (e.g. Yeast) and or rumen and intestinal bacteria and aims to promote a balance of the microbial flora, providing a more efficient digestion of nutrients and then improving the processing of food transformation in milk and meat without these microorganisms are adsorbed and retained in the tissue (Vieira et al., 2014). Probiotics are non-pathogenic microbes that occur in nature and function in the gastrointestinal tract of ruminants
