The benefits of kelp meal for cattle are many and diverse. The benefits are not limited to milk production, but extend to cow condition, immune system, and milk composition. This article will explain the benefits of kelp meal for cattle and its effects on milk composition. We’ll also discuss how to best utilize this nutrient.
A number of animal studies have examined the benefits of Ascophyllum nodosum (kelp meal) for cattle. These studies have concluded that feeding kelp meal to cattle may enhance reproduction, improve health, and reduce milk fever. It is also believed to boost the immune system. This ingredient may also help reduce the temperature of the animals, which may make it beneficial for cattle in hot climates.
In the present study, the maximum daily dose of Ascophyllum nodosum (Ansonia nodosum) for cattle was 158 grams per head. The study by Rey-Crespo, Lopez-Alonso, and Miranda used 100 g/cow/day, whereas the researchers in the present study used a higher concentration of the seaweed, 158 g/cow/day, in their study.
Icelandic kelp meal is a complete feed for cattle that contains more than 70 different minerals, vitamins and enzymes. This nutrient-rich food source can be fed alone or mixed with salt. It helps improve overall health and increases total milk production in dairy cows, improves egg quality in poultry and promotes fertility in sheep.
There is some controversy about this type of feed, with some saying it’s a savior, while others say it can be dangerous. The truth lies somewhere in between. Of course, the truth depends on the individual farm.
Benefits of feeding kelp to livestock
Kelp meal is an important part of livestock feed. It contains dozens of nutrients, including iodine. This trace mineral helps plants and soil thrive. While it’s too expensive to use as a soil amendment, kelp meal is a great choice for livestock feed. It improves animal health and production, enriches manure and compost, and helps reduce methane emissions.
One study showed that cattle consuming kelp meal increased their immunity and reduced their stress levels. Infected cattle, even those that have been vaccinated, suffer from respiratory infections and other diseases, reducing carcass yield and overall health. Seaweeds help boost immunity by stimulating the release of immune mediators, which activate immune cells in the body. This enables the immune system to attack infections and protect the animals.
Effects of feeding kelp on milk composition
There are a number of studies on the effects of feeding kelp meal to cattle on milk composition. These studies have tended to be short-term, ranging from 56 days for heifer calves to 84 days for lactating cows. In these studies, the dairy farmers reported that kelp meal increased the cows’ immune systems and milk production, and showed improvements in animal health. However, future studies are needed to determine the long-term effects of kelp meal supplementation on milk composition.
In one study, researchers found that kelp meal improved the concentration of iodine in milk of cows. Kelp is a rich source of iodine, which is transferred to milk during the winter months. Likewise, kelp has the potential to improve milk composition in summer. However, the authors cautioned that kelp meal is an expensive supplement, and that there are concerns about its toxicity to humans.
Effects of feeding kelp on cortisol levels
A recent study in New Hampshire examined the effects of feeding kelp meal to cattle. During the summer months, 20 Jersey cows were fed diets that contained 0 oz or 4 oz of kelp meal daily. The difference in cortisol levels between these two groups was not statistically significant. This suggests that the kelp may help regulate the cows’ core temperature and reduce stress responses.
Currently, the only studies conducted on cattle and the effects of kelp meal feeding are short-term. The study durations ranged from 56 days for heifer calves to 84 days for lactating cows. However, dairy farmers who use kelp meal have reported improved animal health and immune function. They also reported fewer incidences of lice and pink eye.
Effects of feeding kelp on iodine concentration in milk
The authors of the study assessed the effect of feeding kelp meal to cattle on iodine concentration in the milk and serum. The kelp-fed group exhibited a greater increase in serum iodine concentration compared to the control group. This increase was statistically significant. The increase in serum iodine concentration did not prevent bacterial growth in milk or tears, as was hypothesized. Furthermore, the increased concentration of iodine in milk would not prevent the development of infectious bovine keratoconjunctivitis.
Kelp was fed to Holstein Friesian cattle, which were individually weighed. The researchers administered 56 grams of kelp per day to each animal in the experiment. Kelp meal was manually top dressed and mixed into TMR at two feedings, one in the morning and one in the evening. Milk iodine concentration in the milk was higher in the kelp-fed group than in the control group at d 30.
