I spent quite a bit of time on the Purina website recently. I moved to another barn and the BO uses it, and quite a few vets recommend it. I’ve been using Blue Seal Sentinel LS for years for my 27 y.o. gelding. it’s appropriate for senior horses and hard keepers. High Fat, high fiber, low carbs, extruded the same as the senior formula. It is manufactured in Vermont (we are in Maine), sometimes in New York. I was looking for a reason to change so i didn’t have to buy my own grain. I didn’t find one. In fact, there are a few things that I don’t like.
There are two Purina senior formulas. Equine Senior Active is the original Purina senior formula. Senior Active is performance, concentrate, pelleted. Senior is Special Needs, complete, pelleted and extruded. The complete feed has hay included so it can be substituted when the horse can’t chew enough hay. The concentrate can be used if the horse can eat enough hay.
What didn’t i like?
No list of ingredients on the website. I looked at bags in the grain room, they used a tag.
Senior products are either all pelleted or a combination of pelleted and extruded.
Purina website: “Your horse has nutrient requirements to feel, look and perform his best – not ingredient requirements. As a result, it’s important to pay close attention to what nutrients are in your horse’s feed and where those nutrients are s…”
“Least-cost” formulations allow a manufacturer to adjust and even switch out ingredients based on cost if the formula still meets the guaranteed analysis."
“However, changing ingredients can dramatically change how the diet affects the horse.”
“Let’s look at soybean meal and cottonseed meal. These two ingredients have similar crude protein levels, but cottonseed meal doesn’t provide the same quality of protein (i.e. amino acid composition) to support growth as soybean meal.”
“We make very small adjustments in the amounts of ingredients utilized in the formula to maintain consistent nutrient concentrations in the finished product.”
I haven’t figured out how they can say they make small adjustments in ingredients to guarantee nutrients for their complete/concentrates products. A manufacturer using “least cost” can make small changes in ingredients based on cost as long as they meet the guaranteed analysis for nutrients.
Blue Seal has a list of ingredients on the bag and the website. If they decide to change a recipe the ingredients list and the new bags are required before it goes on the shelf.
I understood that extruded products are easier to chew and digest than pelleted products. That makes me wonder if Purina manufactures common parts of several formulas as pellets and mixes them into several different products.
Blue Seal marked 150 years manufacturing grain in New England a couple of years ago. Kent Nutrition Group comprises Kent and Blue Seal. Not quite small and local, but I’ll take regional organizations who can tell me where the product is manufactured. What’s in the bag is on the bag.
The biggest hump with Purina in my experience was back in the 70s. I was feeding Purina Cat Chow to my kitty and he was always throwing up. It was the grain swelling up after he ate it and there wasn’t enough room in his stomach.
