Subcutaneous injection can cause a transient local tissue reaction that may result in trim loss of edible tissue at slaughter.

Enroflox 100 contains different excipients than other enrofloxacin products. The safety and efficacy of this formulation in species other than cattle and swine have not been determined. Quinolone-class drugs should be used with caution in animals with known or suspected Central Nervous System (CNS) disorders. In such animals, quinolones have, in rare instances, been associated with CNS stimulation which may lead to convulsive seizures. Quinolone-class drugs have been shown to produce erosions of cartilage of weight-bearing joints and other signs of arthropathy in immature animals of various species. See Animal Safety section for additional information.

ADVERSE REACTIONS: No adverse reactions were observed during clinical trials.

ANIMAL SAFETY:

In cattle safety studies, clinical signs of depression, incoordination and muscle fasciculation were observed in calves when doses of 15 or 25 mg/kg were administered for 10 to 15 days. Clinical signs of depression, inappetance and incoordination were observed when a dose of 50 mg/kg was administered for 3 days. An injection site study conducted in feeder calves demonstrated that the formulation may induce a transient reaction in the subcutaneous tissue and underlying muscle.

In swine safety studies, incidental lameness of short duration was observed in all groups, including the saline-treated controls. Musculoskeletal stiffness was observed following the 15 and 25 mg/kg treatments with clinical signs appearing during the second week of treatment. Clinical signs of lameness improved after treatment ceased and most animals were clinically normal at necropsy. An injection site study conducted in pigs demonstrated that the formulation may induce a transient reaction in the subcutaneous tissue.

Fall is here. We can see it in the turning color of the big blue stem, in the rushing of our children back to school, in the fields as we begin to collect our hard work of summer, and in the feedlot as the fresh bawling calves begin to arrive. This changing of seasons is reflected in our database as BRD pull risk increases sharply, more than doubling, beginning in August and persisting until spring. BRD pull risk and BRD deaths rise and fall together in this seasonal pattern. Our expectations are for this to occur, we accept it and brace for the storm, but we could be looking at this as an opportunity. Recognizing that the needs of each arrival group vary, we have a great opportunity before us. By meeting each new group of arrivals, reading each pen, and assessing their needs, we can match their needs with our skills.

As cattle arrive, they take a fresh look at their environment, assessing it for danger and safety. The perception that cattle have of their new home, or the perception that caregivers convey to newly arrived cattle, can change their risk categories. This vital opportunity is a prime time to review the principles of animal wellbeing as guided by the five freedoms. These freedoms, as originally described in a report to the British parliament in 1965, and our ability to utilize their principles to help break seasonal BRD mortality is described below:

 Freedom from hunger or thirst – Just providing ready access to fresh water and feed is sometimes not enough. It’s important to keep in mind that each animal has its own peculiar response to a new environment. Some may rush the bunk while others lack the confidence to approach or find it. By using acclimation to approach this freedom, we can build their trust in caregivers, water, feed, and their environment. Time invested can result in an increased daily feed intake, health, and performance.

 Freedom from discomfort –Timely pen surface management, bedding, and sanitation will encourage and enable cattle to move and rest with comfort. Having the maintenance team adequately prepare pens before cattle are even bought is important to assure this freedom is met. Having a bit of foresight in the summer to prepare for fall can prevent the time crunch experienced in preparing pens for new arrivals.

 Freedom from pain, injury, or disease – As newly arrived cattle share clinical signs, we can focus on assessing lameness and disease by reviewing case definitions and signs of disease with our new and experienced crew members.

 Freedom to express normal behavior – Normal behavior is best assessed by the cattle’s willingness to express orderly motion and exuberance. Combining adequate footing, full rumens, a sense of security in the environment, and being physically well leads to play and exuberance. These normal behaviors can be viewed as an overall assessment of how well the freedoms are being met.

 Freedom from anxiety and distress – Anxiety and distress can be generated during major events in a calf’s life such as weaning, transport, and disease. Often times, the calves that we receive in fall are going through all three of these events simultaneously. These times of stress cause a rise in systemic cortisol which may suppress appetite and the immune system, leaving the calves at a greater risk for disease and poorer response to vaccination. By utilizing low stress cattle handling techniques and acclimation, we can do our part to help reduce social and environmental stressors that contribute to this rise in cortisol. Confidence in their new home facilitates achieving the other four freedoms.
