“…However, during this same period, the mean weight of injection-site lesion trim increased (P < 0.05) from 102.63 ±12.56 g to 152.81 ± 13.24 g. Eighty percent of lesions examined during this period were classified as chronologically "older" (George et al ,1996). The frequency of lesions in beef rounds significantly declined 5 percentage points between 1998 and 1999 and 6 percentage points between 1999 and 2000 in the US (Roeber , 2002) .…”

Food safety has become a very important issue in our society. Modern livestock management practices rely upon the prudent use of injectable antibiotics and vaccines for the purpose of maintain herd health and productivity. Rasmussen (1980) concluded that both the active pharmaceutical and the carrier-vehicle administered are responsible for tissue injury. Now we need to put great emphasis on improper injections which can lead to trimming and discarding of expensive cuts, and learn to use a proper injection method to cause less injection site blemishes as a costly problem for the beef industry. This paper examines the effect of needle based injections and makes a case for using needle-free injections for all but intravenous targets. Results from research on estimating the value of carcass information and potential improvement in pricing accuracy with injections are reviewed. Lastly, management implications are discussed for producers choosing proper injection systems to fed cattle.

“…Therefore, the objective of this study was to evaluate the frequency and presence of injection-site lesions in the outside round muscles of cows. Evaluating the frequencies and severity of injection sites allows each segment of the beef and dairy industries to evaluate the progress made since the audit conducted by Roeber et al (2002) , as well as continue to create better management practices for the future.…”

The frequency and severity of injection-site lesions in the outside round muscles of both beef and dairy cattle were evaluated through a series of audits. Audits were conducted in 2017 on 1,300 rounds from dairy and beef cows from seven locations throughout the United States. Outside round muscles were butterfly cut into 1.25-cm slices and, if present, lesions were counted, measured, and categorized. Rounds from beef (7%) and dairy cattle (15%) had at least one injection-site lesion present. The most common location of injection-site lesions was quadrant 2 and 3, which contained both the biceps femoris and semitendinosus muscles. Injection-site lesions were more frequent (P < 0.05) in the biceps femoris for both beef and dairy rounds. Clear lesions accounted for 57% of injection-sites in both beef and dairy rounds, whereas metallic lesions made up 23% of the total in beef and 25% in dairy. Overall, there was a dramatic decline in the frequency (P < 0.05) of injection-site lesions since the 1998 (24 and 45 percentage units greater in beef and dairy rounds, respectively) and 2000 audits (13 and 20 percentage units greater in beef and dairy rounds, respectively). Educational programs, such as Beef Quality Assurance (BQA) and requirements for BQA training, have resulted in substantial improvements in beef management practices for both the beef and dairy industries.

“…However, when considering only the answers submitted by dairy producers, 46.4% of respondents identified the neck region as the preferred location for injections, with 18.6 and 22.1% preferring the top of the hip and the lower rear leg, respectively. Moreover, research has shown that dairy cow carcasses have significantly more injection-site lesions in outside round muscles than beef cow carcasses (49 and 26%, respectively), illustrating that BQA practices are lacking on many dairy operations (Roeber et al, 2002).…”

“…A survey examining California dairy operations found that producers were hesitant to participate in a quality assurance program, primarily for financial reasons, indicating that the costs were likely to outweigh any benefits from the program (Payne et al, 1999). This logic is in direct disagreement with projections that indicate that injection-site lesions result in an astounding $9,000,000 loss to the beef and dairy industries (Roeber et al, 2002). It has been estimated that quality defects were responsible for a deduction of $68.82 per cow, with injection site blemishes accounting for $11.49 to $13.82 of that loss (Roeber et al, 2001;Tozer et al, 2005;Glaze and Chahine, 2009;Ahola et al, 2011).…”

A survey was conducted on Colorado dairies to assess attitudes and practices regarding Dairy Beef Quality Assurance (DBQA). The objectives were to (1) assess the need for a new handling facility that would allow all injections to be administered via DBQA standards; (2) establish if Colorado dairy producers are concerned with DBQA; and (3) assess differences in responses between dairy owners and herdsmen. Of the 95 dairies contacted, 20 (21%) agreed to participate, with a median herd size of 1,178. When asked to rank the following 7 traits--efficiency, animal safety, human safety, ease of animal handling, ease of operation, inject per Beef Quality Assurance (BQA) procedures, and cost--in order of priority when designing a new handling facility, human and animal safety were ranked highest in priority (first or second) by the majority of participants, with ease of animal handling and efficiency ranked next. Interestingly, the administration of injections per BQA standards was ranked sixth or seventh by most participants. Respondents estimated the average annual income from the sale of cull cows to be 4.6% of all dairy income, with 50% receiving at least one carcass discount or condemnation in the past 12 mo. Although almost all of the participating dairy farmers stated that the preferred injection site for medications was the neck region, a significant number admitted to using alternate injection sites. In contrast, no difference was found between responses regarding the preferred and actual location for intravenous injections. Although most participating producers are aware of BQA injection guidelines, they perceive efficiency as more important, which could result in injections being administered in locations not promoted by BQA. Dairy owners and herdsmen disagreed in whether or not workers had been injured in the animal handling area in the last 12 mo. Handling facilities that allow for an efficient and safe way to administer drugs according to BQA guidelines and educational opportunities that highlight the effect of improved DBQA on profitability could prove useful. Dairy producers play a key role in ensuring that dairy beef is safe and high quality, and just as they are committed to producing safe and nutritious milk for their customers, they should be committed to producing the best quality beef.
