Breast milk is produced from the nutrients we have in our body, so it totally depends on what the mother eats and, to ensure the best quality, it is necessary to follow a balanced, healthy and varied diet rich in a series of vitamins and minerals

Breast milk is the best food for the baby in its first months of life forever. But, although breast milk is always a good food, we can make it even better and more complete if we make sure to follow a healthy diet. Thus, there are many foods that benefit the health of our baby, just as there are others that should be avoided in these months.


Tips for a healthy diet in breastfeeding


While you are breastfeeding, you should take into account the following tips so that your milk has the best possible quality and has all the nutrients your little one needs:


- Drink about two liters of water up to date.


- It includes zinc rich foods, mineral that can be compromised in breastfeeding (cereals, nuts, legumes and liver). You should also consume enough iodine. Choose iodized salt and foods such as fish. And food with selenium, present in meat and fish.

Allergy to cow's milk protein in babies

Cow's milk protein allergy (APLV) is the most common allergy in infants and children. It occurs when a child's immune system identifies the proteins contained in cow's milk as dangerous, which triggers an allergic reaction. However, unlike what happens with other types of allergy, children affected by PLV can acquire tolerance in the first years of life.


- It is important to increase the amount of some fat-soluble vitamins because their presence in milk depends directly on what the mother eats. Mainly, you must ensure the consumption of Vitamin A (found in animal products such as milk, egg yolk, fish liver or colored vegetables), and Vitamin E (present in vegetable oils, avocado, nuts, legumes and fish).


- As for water-soluble vitamins, they do not accumulate in our body but their excess is eliminated in the urine, so you should consume daily foods rich in B vitamins. Vitamins B1, B2, B3 or niacin are found in both plant and animal foods. They abound in foods such as liver, fish, eggs and dairy, as well as in some high-fiber foods such as legumes, whole grains and some vegetables. The vitamin B9 or folic acid We find it in green leaf foods (chard, spinach, escarole, etc.), nuts (especially hazelnuts), whole grains and fruits such as orange and strawberries. And finally, the vitamin C It is in citrus and vegetables like peppers.


Super foods you should include


In addition to following a diet based on the recommendations indicated above, you can include these foods that help increase the quality and quantity of breast milk:


1- Coconut oil


It is beneficial because it contains a lot of nutrients and good fat that helps your milk also have excellent fat for your baby. You must buy it in raw and solid. Coconut oil and liquid is not good.


2- Nuts


Nuts, consumed in moderation, increase good milk fats.


3- Avocado


Avocados are the food (not counting breast milk) with the best type of fat because it has a large amount of oleic acid, a monounsaturated fatty acid, and also omega 3 and omega 6 fatty acids that are really beneficial for health.


4- Oatmeal


A single cup of milk in the morning helps maintain a good amount of milk. Among many other benefits, it has a large amount of omega 3 and linoleic acids, known as "good fats."


Food and drinks to avoid


- Very fatty foods

- Drinks with alcohol as it passes into the blood and from there to breast milk

- Tobacco, very harmful during breastfeeding

- Exciting drinks (moderate consumption)

- Foods that can alter the taste of milk: Artichokes, radish sprouts, sprouts, large amounts of garlic and raw onion, as well as spicy and irritating spices.

Summary of the presentation by Jud Heinrichs, professor at the Univers> Published in Campo Galego.

Increase milk production, but especially solids, mainly fat, should be an objective for all farmers, given that the dairy industry will pay more and more according to the dry milk extract.

In this sense, the multinational Alltech organized last June at the Center for Agricultural Research of Mabegondo (CIAM) a day on improving the qualities of milk. The presentation was given by Jud Heinrichs, a professor at the University of Pennsylvania, and an international reference in milk cattle feeding.

In a didactic way, he explained the keys to improve milk fat performance through daily management:

The importance of rumen PH:

A healthy rumen allows the cow to absorb nutrients well and can produce milk with high levels of fat and protein. In this regard, the American professor recommended "Not to reach a situation of acidosis, in which the hairiness of the rumen deteriorates, although it is punctual, because it penalizes the intake, the absorption of nutrients and the production, and it is very difficult to recover the previous situation".

In this regard, he recalled that “The ideal is to maintain a ruminal PH level of 6” and warned that in the case of cows in production to which the feed is administered separately - for example in those that graze - “When eating the feed two or three times a day during milking, and digest it quickly, what is caused is a decrease in ruminal pH up to 5.2, which after digesting grass again goes back up to 6.8 ”.

In addition, he warned that “With low ruminal pH, the growth of the bacteria responsible for digesting the fiber of the fodder is paralyzed, and the production of acetic acid, a precursor of milk fat, decreases, and there is a depression of the amount of global protein in the rumen , in addition to a reduction in dry matter intake ”.

"It is very common that when there is a lower intake of food by the cows the farmer tends to chop the ration more, but that way the fat and milk protein will not rise"he added.

On the other hand, Jud Heinrichs stressed that comparing the mixer with the grazing system, the first is usually between 5 and 15% more efficient for the production of fat in milk, because "The use of nutrients in fodder, in terms of carbohydrates is better, and not giving the feed only the oscillations of ruminal PH are also smaller, between 5.8 and 6.2".

In both cases, adding live yeasts to the ration can be an effective solution to correct ruminal PH oscillations and improve rumen functioning.

Variation of ruminal PH in grazing, between 6.8, when the cow is grazing, and 5.2, when it eats the feed:

Proportion of feed and feed in the ration:

According to Jud Heinrichs, the fodder must represent a minimum of 55% of the weight of the dry matter of the ration. "In the United States in the past, we worked with rations with more concentrate than fodder, feeding the cows as if they were pigs, but that was abandoned because it caused lower levels of fat and protein in milk and more acidosis problems"he explained.

In this sense, the professor at the University of Pennsylvania explained how the ratio of fodder and ration concentrate affects the ratio between acidic acid and propionic acid.

“With 100% fodder, the nutritional needs, especially energy, of a cow with high milk production would not be met. And with a ratio of 60% concentrate and 40% fodder we would have a ratio of 2.3: 1, and below that ratio we should not pass. The ideal is 65% fodder, but taking into account the effective fodder, the one that eats the cow, because we can be in a theoretical ration of 60% of concentrate and 40% of fodder, but the real one is 50 % each"explained Jud Heinrichs.

Influence of the proportion of forage and feed of the ration in the production of acetic and propionic acid in the rumen:

Avoid overcrowding:

Overcrowding may be due to the fact that there are fewer places than animals or because cows access the manger poorly, so that when they do they will perform a large and fast food, causing a decrease in rumen PH, which is subsequently recovered as the cow makes smaller meals. When the barn is saturated and the cornices are self-processing, and not freely accessible, the situation still worsens.

"Overcrowding is a fairly frequent situation that causes livestock that could produce milk with 3.8% fat, are in 3.5, and that is enough money"he assured.

In this regard, he recommended spend more time observing the behavior of cows to see if they all eat at the same timeIf they choose the food and therefore the ration on the paper does not correspond with the real one, measure how many hours the cows are outside the manger or if the ration in the car is always done in the same way.

The milking robot:

With the installation of the robot it is normal for the cow to be milked between 4 and 5 times a day, and receive each dose of feed every time. However, Jud Heinrichs warned that if the type of feed does not change, the qualities of fat in milk may decrease due to a decrease in rumen PH.

In this regard, Jud Heinrichs recommendations are to put in the robot the minimum of feed, just enough for the cow to go milking - the average is between 4 and 5 kilos of robot feed per cow and day-, choose a feed with more starch, more digestible, and in pellet format, with more fiber, while the more protein feed would go in the mixer car.
