Purina Wind & Rain Texas All Season 7.5 Complete ALTOSID Fly Control Cattle Mineral

Best for: operations needing year-round mineral nutrition with built-in fly control for cattle grazing across seasons. This product combines essential macro and trace minerals with vitamins A, D, and E to support health and reproduction, plus ALTOSID fly control for larval suppression. It’s a strong all-season option when consistent intake is achievable.
Why selected: It addresses mineral deficiencies common in forages year-round, provides vitamins to support herd health, and uses ALTOSID to target fly larvae, reducing fly pressure as cattle consume the mineral daily. Choose this if your herd benefits from a single, ready-for-use mineral with integrated fly control.
Caution: Availability and effectiveness may be influenced by how consistently cattle access and consume the mineral. In dry or highly variable pastures, ensure licking activity is steady to maintain target intake.
JustiFLY Feedthrough Cattle Fly Control, Single

Best for: small farms or operations testing feedthrough fly control before scaling up. This single 360 g add-pack is designed to treat one 50-lb bag of free-choice mineral, providing a cost-effective entry point into larvicide-based fly control.
Why selected: It offers a simple method to integrate fly control into free-choice mineral without major changes to feeding routines. It’s a clear option if you want a minimal commitment while evaluating effectiveness.
Caution: Results depend on consistent use of the add-pack with mineral and proper distribution across feeding sites. Different cattle densities may affect the treatment coverage per herd.
JustiFLY Feedthrough Cattle Fly Control (3 Pack)

Best for: operations that want multiple mineral add-packs to cover larger herds or longer sampling periods without frequent restocking.
Why selected: The 3-pack provides a practical balance between cost and quantity, ensuring sustained fly control with mineral supplementation across weeks or months. It’s a reliable choice when wall or feeder space can support several add-packs at once.
Caution: Ensure the add-packs are stored properly to prevent moisture damage; ineffective storage could reduce larvicide efficacy over time.
JustiFLY Feedthrough Cattle Fly Control (6 Pack)

Best for: larger herds or operations seeking ongoing fly control with sustained mineral intake across multiple feeding sites.
Why selected: The six-pack format supports broader distribution and reduces the frequency of reordering, helping maintain constant fly suppression while cattle receive minerals. It’s a practical choice for medium-to-large operations.
Caution: As with all feedthrough products, consistent use and proper mixing with free-choice mineral are essential to achieve the desired control levels.
JustiFLY Fly-Through Salt Block for Cattle Fly Control

Best for: pastured cattle where mineral and salt are consumed together, with a focus on fly control during the fly season without additional handling.
Why selected: Salt blocks offer a dual-purpose solution—salt supplementation and fly control through larvicidal action embedded in the mineral matrix. It’s ideal for extensive grazing setups with minimal handling.
Caution: Salt-based products may lead to uneven intake if cattle have diverse salt preferences or if mineral content is not sufficiently palatable for all individuals. Monitor consumption across the herd.
Buying Guide: Key Considerations For Cattle Mineral Feeders With Fly Control
- Type of Fly Control: Choose feedthrough larvicides (JustiFLY) for ongoing larval disruption or ALTOSID-based mineral blends for integrated fly suppression alongside minerals.
- Mineral Nutrition: Ensure the product provides essential macro and trace minerals sufficient for your cattle’s life stage and production goals.
- Delivery Method: Consider free-choice mineral vs. salt blocks. Free-choice options support steady intake, while blocks reduce handling but may yield variable consumption.
- Feeding Environment: Assess pasture size, feeder availability, and cattle access to ensure consistent intake and coverage of all animals in the herd.
- Storage and Handling: Protect add-packs from moisture and heat. Improper storage can reduce efficacy and shelf life.
- Herd Size and Organization: Larger herds benefit from multi-pack options that ensure uninterrupted supply, while smaller herds can start with a single pack.
- Monitoring: Track consumption levels and fly activity to gauge effectiveness and adjust product choice or quantity as needed.
Frequently Asked Questions
- What is the main purpose of cattle mineral feeders with fly control?
To provide essential minerals while simultaneously reducing fly populations that affect cattle health and comfort, typically through larvicide or integrated fly-control formulations.
- Which option is best for a large grazing operation?
Multi-pack JustiFLY feedthrough options or a large-format mineral with ALTOSID fly control are typically best for sustained, widespread coverage.
- Are mineral feed-through products safe for all cattle?
Yes, when used as directed. Follow product packaging for dosing and feeding guidelines to ensure safety and efficacy for different life stages.
- When should I start fly-control mineral programs?
Begin early in the fly season and maintain consistent consumption throughout the season for best results.
- Can I combine different JustiFLY products?
Yes, but ensure compatibility with your feeding system and avoid over-supplementation by monitoring mineral levels and intake.
- What should I do if cattle aren’t consuming the mineral consistently?
Check palatability, placement of feeders, and overall herd health. Consider a different formulation or a block option to improve intake.
