Feeding rumen protected calcium gluconate increases milk production on 2 dairy farms in Poland

Key take-away message

  • Selko LactiBute increased milk production of dairy cattle on 2 Polish farms
  • Differences in milk production of up to 2.7 litres of milk per day were observed

Selko LactiBute improved lactational performance and increased milk solids on a Polish farm during periods of heat stress
Selko LactiBute for dairy cows contains rumen protected calcium gluconate which acts as a prebiotic inducing a shift of the microflora. This results in an increase of butyrate and other volatile fatty acids in the hindgut, which improves gut barrier function and reduces the risk of “leaky gut”. Cows suffering from heat stress often have a problem with “leaky gut”. Several trials have shown that animals in heat stress perform better on Selko Lactibute. A polish farmer confirmed these findings, first in heifers, later in the entire herd.

Feeding rumen protected potassium gluconate increases milk production on two Polish farms

Feeding Selko LactiBute reduces systemic inflammation as a result of “leaky gut”

The active component of Selko LactiBute for dairy cows is rumen protected calcium gluconate. Calcium gluconate acts as a prebiotic inducing a shift of the microflora. This results in an increase of butyrate and other volatile fatty acids in the hindgut, which improves gut barrier function and reduces the risk of “leaky gut”. Trials carried out in various research farms and several commercial farms have shown that milk production of dairy cows will increase as a result of feeding Selko LactiBute1,2,3,4. Purpose of the current trial5 was to test Selko LactiBute in two Polish farms.

Material and methods, farm 1

Farm one has a total of 550 cows. A total of 65 cows were included in the trial. Each cow was randomly allocated to one of 2 groups immediately after it calved. Both groups were fed the same TMR with 270 g of starch per kg DM and 180 g of crude protein per kg DM. The trial lasted 120 days. One group was fed 16 grams of Selko LactiBute per cow per day. Milk production of cows and the amount of milk solids were measured on Day 0, day 30, day 60 and day 120 of the trial.

Figure 1: Milk production of dairy cows fed Selko LactiBute compared to controls fed the same diet.

Results, farm 1

Milk production data of cows are presented in figure 1.
Average milk production of cows in the trial over the entire period was 2.35 kg/cow/day higher in dairy cows fed Selko LactiBute. Average production of Energy Corrected Milk (ECM) was increased by 2.77 kg/cow/day.

Materials and methods, farm 2

Farm 2 had 240 cows, milked in 4 robots. A total of 71 cows were included in the trial. Cows stayed in a post calving group for a number of days after calving, so recordings of milk production for the trial started at 30 days after calving and continued until 120 days after calving. Each cow was randomly allocated to one of 2 groups. Both groups of dairy cattle were fed the same TMR with 260 g of starch per kg DM and 170 g of crude protein per kg DM. One group of 35 cows was fed 16 grams of Selko LactiBute per cow per day, the other group of 36 cows served as controls.

Figure 2: Milk production of dairy cows fed Selko LactiBute compared to controls fed the same dairy ration without Selko LactiBute.

Results, farm 2

Milk production data of the cow herd are presented in figure 2. Average milk production of dairy cows over the entire lactation period was 1.85 kg/cow/day higher in dairy cows fed Selko LactiBute.

Conclusion

Selko LactiBute contains rumen protected calcium gluconate, which improves hindgut health and energy partition of dairy cattle. Milk production in the dairy cows included in this study and fed Selko LactiBute was increased on both farms during the entire trial period of 120 days. Average milk production of dairy cows increased by 2.77 kg/day and 1.85 kg/day respectively.

Beyond the rumen of dairy cattle

Feed restriction and heat stress might can cause hind gut acidosis and "leaky gut" in dairy cows. Nutritional strategies can help mitigate the effects of leaky gut in dairy cows. Zinc can reduce oxidative stress in dairy cows and can also improve the immune response. Hydroxy chloride trace minerals have a higher bio-availability than sulfate-based trace minerals. The increased amounts of zinc available to the dairy cow supports better enterocyte health and reduces bacterial infiltration and the occurrence of systemic inflammation in dairy cows.

Rumen protected calcium gluconate increases average daily gain of beef cattle by 95 grams per day

Selko LactiBute improves hindgut health and reduces systemic immune activation in cattle. As a result, starch levels in the faeces decline, faecal pH increases and averag daily gain of beef cattle fed Selko LactiBute is improved by 95 grams/day.

Rumen protected calcium gluconate increases milk production of dairy cows on 3 commercial farms in France

A trial with Selko LactiBute in dairy cattle was carried out on 3 dairy farms in France. Milk production of cows treated with Selko LactiBute was compared to the predicted milk production based on genetic potential of the herd. Selko LactiBute improved persistence of milk production. Before the start of the trial, milk production in all 3 dairy herds was equal to the genetic potential of the dairy cows in the herd. During the 4 month period that the cows were on Selko LactiBute, differences in milk production of up to 2.7 kg of milk per day were observed.

Calcium gluconate increases production of energy corrected milk in dairy cows

Selko LactiBute was tested in 6 Dutch commercial dairy farms. Compared to controls and compared to their genetic potential, dairy cows fed Selko LactiBute had an increase of ECM production of 0.8-1 kg.

The impact of calcium gluconate on volatile fatty acid levels in the hindgut of cattle

A trial in cattle showed that Selko LactiBute, containing rumen protected calcium gluconate had a prebiotic effect in the hindgut of cattle. This resulted in increased levels of acetate and propionate and a trend towards higher levels of butyrate in the hindgut. Butyrate can reduce the risk of hindgut acidosis in dairy cows.

Avoid ‘leaky gut’ by preventing hindgut acidosis in cows

Systemic immune activation results in poor transition to lactation in dairy cows. Recent advances in ruminant nutrition highlight the importance of hindgut acidosis in cattle as a risk factor for a smooth digestive adaptation.

Selko | Transition Management

Transition problems of dairy cows are caused by systemic immune activation

High NEFA's, ketosis and hypocalcaemia are not the cause of transition problems in dairy cows but the result of inflammation that is caused by systemic immune activation that occurs around calving.

Dietary interventions to improve hindgut health of dairy cows

During the transition to lactation, dairy cows have to undergo metabolic adaptation, digestive adaptation and immune adaptation. Recent advances in ruminant nutrition highlight the importance of hindgut health as a prerequisite for a smooth digestive adaptation.

The three core physiological adaptations of dairy cows during transition

Dairy cows undergo 3 core adaptations during the transition to lactation. Digestive, metabolic and immune adaptation need to be succesful to avoid systemic immune activation and inflammation

Not all cows with a high Body Condition Score have problems with their transition to lactation

Mobilisation of body fat in dairy cows in transition is a physiological response to increased demands for energy. Negative energy balance is not a disease. Some cows with a high BCS have a metabotype type that can deal with massive fat mobilisation, others do not have such a metabotype.

Selko | TMR

Selko TMR® is a blend of organic acids that reduces the growth of yeasts, moulds and bacteria such as Enterobacteriaceae like Salmonella. As a result of the reduction in growth of micro-organisms, increases in temperature of the TMR are delayed by at least 6 hours in silages treated with Selko-TMR, resulting in a higher dry matter intake.

Selko | Renergy®

Selko Renergy® is a blend of organic acids that modifies rumen fermentation by increasing propionate production. Propionate is a key source of energy for ruminants and is also the most efficient volatile fatty acid (VFA) produced in the rumen. More energy from propionate in the rumen increases production efficiency.

Even the best heat stress control programme cannot always fully prevent problems with heat stress in dairy cows. Supplementation with Selko NutriCool can help to avoid a drop in dry matter intake and loss of milk production as a result of heat stress.
