How Much Calcium Formate Does Broiler Feed Need To Add To Play A Better Role?

As a feed acidifier, feed additive calcium formate can reduce the pH value of substances in the digestive tract, provide the most suitable digestion environment for animals, and meet the new growth promoter of nutrition acquisition and intestinal bacteriostasis.

However, how much calcium formate needs to be added to feed can play a role, what advantages it has compared with its acidifier, and how to choose calcium formate have become the focus of attention at present.

Taking broilers as an example, the experiment was conducted to determine the effect of organic acids fumaric acid and calcium formate added to feed on broilers.

In the first experiment, male broilers were raised to 21 days old. The addition of fumaric acid and calcium formate were 0, 0.5, 1.0 and 1.5% and 0, 0.5, 1.48, 2.20 and 2.89% respectively. For 5 × The feeding effects of fumaric acid and calcium formate were evaluated by multi factor design.

Conclusion: the addition of 0.5% calcium formate significantly (P < 0.05) promoted the body weight of broilers, but did not affect the feed utilization efficiency. When calcium formate was added more than 1.48%, weight gain and feed utilization efficiency were significantly reduced. There was no significant interaction between fumaric acid and calcium formate.

In the second experiment, male and female broilers were raised to 49 days old, and the feed was supplemented with 0, 0.5, 1.0 and 1.5% calcium formate respectively. The addition of 0.5 or 1.0% calcium formate had a significant effect on weight gain and feed utilization efficiency. The addition of 1.0% calcium formate reduced the weight gain and feed utilization efficiency of 21 and 42 day old male and female broilers.

At 49 days of age, the weight gain and feeding intake of cocks fed with 1.5% calcium formate were significantly different from those fed with the control group, but significantly less than those fed with 0.5 or 1.0% calcium formate.

Conclusion: adding 1.5% calcium formate significantly increased the weight gain of 49 day old hens.

Objective: the purpose of using organic acids together is because fumaric acid is well known to improve the performance of broilers, and its price is much more expensive than calcium formate. The author hopes to explore the possibility of using two sources of organic acids together to improve the performance of broilers. The addition of fumaric acid in feed was 0, 0.5, 1.0 and 1.5%, respectively; Calcium formate was added to the feed to provide 0, 0.5, 1.0, 1.5 and 2.0% formic acid activity respectively.

Experimental discussion:

Adding calcium formate to broiler feed had a positive effect on growth and feed utilization; And adding fumaric acid has a positive effect on broilers, which is consistent with many previous studies. Vogtetal. Reported that adding less than 2% formic acid to broiler feed had no adverse effect on broiler weight. They also found that calcium formate improved the feed utilization of broilers in a curve, and its dosage was about 1.0 and 1.5% when reaching the highest peak utilization. Vogtetal. Found that calcium formate can reduce the number of bacteria in the small intestine and colon of broilers. Calcium formate can promote the performance of broilers. Organic acids can not only reduce the pH value in the environment, but also achieve the purpose of bacteriostasis by destroying bacterial cell membrane, interfering with the synthesis of bacterial enzymes and affecting the replication of bacterial DNA.
