Повний текст джерелаFinding ways to objectively measure welfare within different sectors of the beef industry is necessary to continually improve cattle welfare from birth to slaughter. The first objective of Study 1 was to benchmark cow-calf producer perspectives on management strategies and challenges that ultimately affect cattle welfare on ranches in the United States. The second objective of Study 1 was to quantify how producers are marketing their calf crop, their priorities when selecting replacements, and if producers saw value in handling and care guidelines. A total of 1,414 responses from cow-calf producers in 44 states were collected through a survey done in partnership with BEEF Magazine. Thirty questions were asked of producers to gather demographic information, producers’ current handling and health management practices, and how they prioritized industry challenges. As well as establish at what age and through what avenue producers are marketing their calf crop, and gauge producer perspectives on a quality assessment outlining handling and care guidelines.
After analyses of producer responses, it was concluded that the frequency of management methods and decisions are impacted by age, operation size, location, and BQA certification. A higher percentage of respondents who were BQA certified used electronic eartags, followed by freeze branding. A higher percentage of respondents not BQA certified used basic eartags and hot branding. 74.5% of respondents were preconditioning their calf crop. A higher percentage of respondents were preconditioning their calf crop that were BQA certified, than those who were not BQA certified. The most important beef industry challenge identified was cow-calf health and the biggest challenge to producer’s own operation was identified as land availability/price. The most important animal health issues on producers’ operations were identified as Bovine Respiratory Disease, flies, Pinkeye, and reproductive health. By producer age, calf/neonate health was identified as the biggest challenge for respondents under the age of 30. Respondents age 55-70 responded that Veterinary Feed Directive (VFD)/regulations was more of a challenge than any other age group. Respondents with 50 head or less or more than 1,000 head more frequently retained their calf crop through finishing and respondents with 51 to 200 head and 201 head to 500 head more frequently backgrounded and then sold their calf crop. 13.5% of respondents answered yes, a veterinarian had offered to administer a drug for pain management when castrating or dehorning. Of those 13.5% who responded yes pain management had been offered, 54.55% of respondents chose to use a pain relief method. A higher percentage of producers that precondition also indicated that they use a pain relief method when castrating or dehorning more frequently, though it was still a low percentage. Overall, 46.3% of respondents saw value in handling and care guidelines and 54.9% of respondents saw value in a program including source and age verification, a vaccination plan, and handling and care guidelines. Respondents who were BQA certified, had a beef cow inventory of 501 to 1,000 head, who preconditioned their calves and backgrounded them before selling, and who lived in the West more frequently saw value in a quality assessment outlining handling and care guidelines.
The objective of Study 2 was to examine the effects of captive bolt length and breed type on post-stun leg activity in cattle. A total of 2,850 Holstein (HOL) and non-Holstein British/Continental bred (NHOL) steers and heifers were observed post-stunning at a large commercial slaughter facility. A penetrating pneumatic captive bolt stunner was used with three different bolt lengths: CON, 15.24 cm; MED, 16.51 cm; and LON, 17.78 cm. Hind limb kicking, forelimb activity, take away belt stops, carcass swing and number of knife sticks during exsanguination were recorded for each animal from video recording. Hind limb and forelimb kicks observed ranged from 0 to 25 and 0 to 8, respectively. A significant main effect of treatment, breed type and an interaction between treatment and breed type on hind limb activity was found. Analysis of post-stun hind limb and forelimb activity indicated that increasing pneumatic captive bolt length does not decrease post-stun leg activity but alternatively can increase kicking when using the longest bolt tested in particular types of cattle, i.e. Holsteins. Other parameters associated with the shackling and hoisting process were impacted by breed type as well. There was a higher percentage of cattle experiencing take away belt stops and carcass swing in HOL as compared with NHOL. (Abstract shortened by ProQuest.)

Sustainable food movements are focused on reducing meat consumption for one simple reason: meat is extremely environmentally costly. This enormous resource use by one industry makes it an appealing target for those looking to reduce American resource use. As a result, many are looking at ways to make livestock more sustainable. And there are two main ways to do so. Clover Food Lab represents one idea: a return to local farming with an emphasis on a plant-based diet. Impossible Foods is the second: using biotechnology to provide a sacrifice free alternative, synthetic beef. These companies aren't solutions in of themselves, but proposals on the way solutions should be implemented. The partnership between these two opposing strategies reveals the promises and pitfalls of trying to reform the American diet and, most importantly, that above all else our food system is unsustainable as it is now.

Повний текст джерелаHumans are affected from their surrounding which may control our choices when it comes to food intake. Previous studies highlights the importance of a balanced nutrition which contains equal intake of animal and plant-based protein for the health outcome. The aim of this study is to find out people's knowledge and options of proteins. A web-based survey was sent out via social media in order to gain a wide ranging variety in participants. Amongst the participants, there was a preponderance amongst persons between the ages of 18-32 and people with higher education. The foremost reasons the respondents gave about their choices were costs (price), taste and animal agriculture. Although mainly were highly educated, the results of the study showed lack of knowledge about protein and its purpose. This leaves us to the conclusion that the profession as health promoters is needed to provide continuously and updated information to the public in order to maintain a state of good health.
