The latest round of broker upgrades on ASX All Ords shares are here and you may as well strap in because there's a few names to discuss.

Brokers are bullish on companies ranging from the healthcare sector, to energy, to food, giving investors a good selection of meat to choose from.

Here's a closer look.

ASX All Ords shares in favour: Pro Medicus Ltd (ASX: PME)

Bell Potter doubled its price target on Pro Medicus shares in a note to clients this week, lifting it from $130 to $260, according to The Australian.

The health imaging software leader has recently signed its largest deal ever regarding its Visage system, valued at $330 million.

"We have previously under appreciated the value accretion in contract upgrades", Bell Potter said.

"Contract wins are likely to continue", it added.

Pro Medicus shares were last trading at $264.61 apiece.

ALS Ltd (ASX: ALQ)

ALS was started with a buy rating from Bell Potter with a price target of $17.30. Analysts said ALS is well-positioned to benefit from global demand for laboratory testing services.

The broker sees "compelling value" in the business, including its "capital allocation framework", which has produced over 15% returns on capital employed (ROCE).

At the time of writing, the ASX All Ords share is priced at $15.97 apiece, leaving an 8% upside potential from Bell's price target.

Boss Energy Ltd (ASX: BOE)

Meanwhile, Citi has initiated coverage on Boss Energy with a buy rating this week and a $3.40 price target.

With Boss shares trading at $2.65 apiece at the time of writing, the broker sees 28% upside potential from here.

Tribeca Investment Partners also likes the ASX All Ords share, noting the scaling global demand for nuclear energy.

This has been driven in part by recent investment in artificial intelligence (AI)- related ventures, such as data centres.

The firm says we are at the cusp of "a new energy paradigm", putting companies like Boss centre stage.

Bell Potter has also upgraded Integral Diagnostics to a buy with a target price of $3.87.
