Summary
Most Saskatchewan dairy producers use anthelmintics routinely, despite low concern about parasite resistance. This practice, coupled with visual dose estimation, may increase the risk of anthelmintic resistance in cattle.
Area of Science:
- Veterinary Parasitology
- Animal Husbandry
- Antimicrobial Resistance
Background:
- Endoparasite control is crucial in cattle management.
- Anthelmintic resistance is a growing global concern.
- Understanding producer practices is key to mitigating resistance.
Purpose of the Study:
- To assess pasture management and parasite control product use in Saskatchewan dairy producers.
- To evaluate producer attitudes towards endoparasites and anthelmintic resistance.
- To identify risk factors for the development of anthelmintic resistance.
Main Methods:
- A questionnaire was distributed to 161 Saskatchewan dairy producers in 2016.
- A response rate of 39.8% (64 producers) was achieved.
- Data collected included pasture management, anthelmintic use, and resistance awareness.
Main Results:
- Most producers (78.3%) were unconcerned about endoparasites and anthelmintic resistance.
- A high percentage (79.7%) used anthelmintics across all cattle classes.
- Routine use and visual weight estimation for dosing were common practices.
Conclusions:
- Current anthelmintic use patterns in Saskatchewan dairy herds may promote resistance.
- Producer education on parasite threats and responsible drug use is needed.
- Further research into resistance prevalence and management strategies is warranted.

01:16Characteristics of Practical Op Amps

A difference amplifier, a crucial component in numerous electronic devices, ideally amplifies only the difference-mode signal, which is the difference between two input signals. However, in practical circuits, the output voltage depends on both the differential gain and the common-mode gain.
The ratio of differential gain to the common-mode gain is defined as the common-mode rejection ratio (CMRR). This ratio quantifies the ability of operational amplifiers (op-amps) to reject common-mode...

17.3K
Theories play an essential role in organizing patient care. Theories refer to a proposed or followed belief, policy, or procedure that is the basis for action. Nursing theories are knowledge-based concepts that guide nurses' actions, influence nursing education and practice, and allow nurses to care for their patients.
Theories provide a perspective to assess patients' conditions and organize data and methods. They also assist in analyzing and interpreting information. They represent a...

01:28Equivalent Circuits for Practical Transformers
1.4K
The practical equivalent circuits of single-phase two-winding transformers exhibit significant deviations from their idealized versions due to the inherent properties of winding resistance and finite core permeability. These properties result in real and reactive power losses, affecting the transformer's performance. Understanding these deviations is crucial for designing more efficient transformers.
In a practical transformer, each winding exhibits resistance and leakage reactance. The...

01:21Control System Problem
421
In an open-loop system, such as a basic thermostat, the poles of the transfer function influence the system's response but do not determine its stability. However, when feedback is introduced to form a closed-loop system, such as an advanced thermostat that adjusts heating based on room temperature, stability is governed by the new poles of the closed-loop transfer function.
When forming a closed-loop system, issues can arise if the poles cross into the unstable region, leading to potential...

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

02:33Combinatorial Gene Control
9.5K
Combinatorial gene control is the synergistic action of several transcriptional factors to regulate the expression of a single gene. The absence of one or more of these factors may lead to a significant difference in the level of gene expression or repression.
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...
