Summarize this article:

If a stream or river runs through a paddock space, it can provide a source of water for your cattle. You can construct an access ramp, so that cows can access the water easier without polluting it. Or, you can use a siphon system to fill up water tanks from this source.  Another alternative is to install an animal-operated pasture pump. This is a water pump that is triggered by a cow’s nose pressing against the lever in the water tank. Then, the water is automatically siphoned up from the river to fill the tank. If you are using a freshwater spring or river as a water source, it’s important to clean it out periodically to ensure that it doesn’t become contaminated and spread disease. As a general rule, cattle need daily access to between 1-2 gallons of fresh water per 100 pounds of body weight. This means that you’ll want at least 1 tank per paddock that can hold the minimal amount of daily water for the animals in that space. Pastured cattle can survive by primarily eating grass. However, if your cattle are primarily in a dry-lot or if the weather is poor, then supplementing with grain or hay is a good idea. Talk with your vet about which grain or hay to use and how much to feed your cattle.  Use a hay rack or clean feed container in a paddock or barn to give your cattle hay or grain. Wet, moldy food can actually sicken your animals. If the hay or grain gets wet, discard it immediately. Feeding your cattle grain helps you to form a positive relationship with them, too. They’ll associate you with food and are more likely to come to your calls. Cattle can’t store salt in their system, which means that they need to ingest it daily for health. Fill up a feeder with a fortified trace mineral salt mixture and place it near where your cattle sleep at night whether in a paddock or barn. In addition, place at least 1 rock salt and mineral-blend block in each paddock.  You can purchase these salt products at your local feed store or even online through an agricultural supply company. As a general rule, a 1,300-1,400 pound cow will need between 35-45 grams of salt per day. If you have 100 cows, then you’ll need about a 55 pound bag of mineral salt mixture each week. If your cows balk at the taste of the salt mixture, try stirring in some dried molasses to improve the flavor. Your vet will be able to tell you which vaccinations are suggested for your cattle. Some shots you may be able to give on your own, but others will require a vet visit. It’s also important to monitor your dry-lot cattle especially closely, as they are more prone to illnesses, such as pneumonia.  A dry-lot is a fenced area that is free from grass. Most cattle owners rotate their animals between dry-lots, grassed areas, and enclosures. Dry-lot cattle often suffer from respiratory illnesses caused by the dust in the air. Cattle vaccinations can help to protect your animals from diseases, such as blackleg or Bovine Viral Diarrhea (BVD). Monitor the health of your bulls closely during breeding season, as they can injure one another in the process of competition for breeding rights.

Summary:
Supply fresh water for your cattle. Supplement their diet with feed. Provide a source of salt. Work with a livestock vet to monitor your herd’s health.
