Because the animal-health industry is an essential input for livestock-based agriculture, demand for animal-health products is both reliable and growing. This makes animal-health companies a great way to round out a balanced healthcare portfolio with stocks that don't face the same set of risks as companies devoted to human healthcare. If you're looking for quick stock picks in the animal-health sector, don't miss these three leading animal-health companies worth buying in the short term.

Zoetis

With a market cap of $65.01 billion and trailing 12-month revenues of $6.34 billion, Zoetis (ZTS 0.43%) is the world's single largest animal-health company. Zoetis's profit margin is an impressive 25.41%, exceeded only by its phenomenal 63.55% return on equity. Both of these metrics, in addition to its year-over-year quarterly earnings growth of 35.6%, indicate that Zoetis is a very well-run company.

Financials aside, Zoetis has a massive roster of diagnostic tests, therapeutic drugs, vaccines, and other products for pets and livestock. The company's most recent product release is a Simparica Trio, a preventative treatment for dogs at risk of acquiring parasites. Given the company's typical tempo for releasing new products, investors can expect at least two new offerings to hit the market by the end of the year. 

There's also evidence that Zoetis may be expanding into new markets within the animal-health industry in the short term. In April, the company acquired Performance Livestock Analytics, a cloud-based analytics platform targeted at large livestock farmers. Keep an eye on Zoetis's news feed to see how the company plans to use its acquisition to expand into new markets, but don't be afraid to make a purchase before an announcement.

Elanco

Elanco (ELAN -0.58%) is a smaller animal-health company than Zoetis, with a market cap of $8.64 billion and trailing 12-month revenues of $3 billion. But, with more than 125 product lines for pets and livestock, and operations in more than 90 countries, Elanco still has a lot to offer investors interested in buying for the long term. 

In June, Elanco announced that European regulators had approved its acquisition of Bayer's (BAYN) animal-health division for $5.32 billion in cash and $2.28 billion in shares. To raise cash for the deal, Elanco used a combination of debt and new equity that it expects to pay off by 2022. Since the acquisition's initiation in late 2019, Elanco has divested from numerous Bayer animal-health products to raise cash, including a February sale to Merck (MRK -0.03%) for $55 million in cash. Integrating this new acquisition is one of the top priorities for Elanco's leadership moving into the second half of 2020, as is increasing the company's profitability beyond its current negative 0.42%. 

In the long term, Elanco's purchase from Bayer will pay off. The company expects that its revenues will increase by $1 billion by 2023 in addition to around $275 million in synergies and cost reductions. Furthermore, the acquisition has given Elanco eight new pipeline projects and more than 30 life-cycle projects, shoring up its offerings substantially.

Elanco has been hit hard by the pandemic, and it expects to suffer additional struggles through the rest of the year. In its latest earnings report, the company stated that its quarterly revenue growth year over year had dropped by 10%. The company's next earnings report later this summer will likely reflect the toll that the pandemic and difficult trade conditions have inflicted on the company's bottom line, making it a great time to buy. 

Covetrus

For speculators seeking rapid returns, Covetrus (CVET) is notable for its explosive growth of more than 40% in the last month. Unlike the other animal-health companies covered here, Covetrus produces software for managing veterinary prescriptions, animal-health supply chains, and veterinary practices. This means that Covetrus isn't exposed to as much supply-chain risk or product-development risk as other animal health companies, and it also means that its marginal cost of production is significantly lower.

Sales have steadily increased, though the company still isn't profitable. Covetrus' earned the company $1.07 billion in the first quarter of this year, an increase of 13% compared to 2019. In April, Covetrus announced a $250 million convertible preferred-equity investment from a private investment firm which was already a shareholder. The purpose of the investment was to provide Covetrus with short-term liquidity and to support its continued operational expansions in the face of the pandemic. 

While Covetrus appears to be surging right now, and its sales growth suggests a bright future for the company, it's unclear how long its road to profitability will be. Grab the stock while it's still hot, and don't be afraid to back out of your position early if the remaining earnings reports this year show the company's sales growth ebbing substantially.
