pigs

There are around 4.76 million pigs kept on agricultural holdings in the UK. With the UK pork market valued at £1.44 billion in 2020 (Statista). 

There are 3 stages in pig production. 

Pregnant breeding sows can be held in sow stalls, group housing or outdoor systems. Sow stalls were completely banned in the UK in 1999 whilst they are still permitted for a restricted 4 weeks after mating in the EU. Pregnant sows can be held in group housing, this allows the sows to move and socialise, however, this comes with other risks of aggression if conditions allow and management is loose.

The third is outdoor systems, which allows sows the greatest freedom and access to the outdoors and natural environment. The sows have bedded shelters to shelter from the weather and are held in groups of similar sizes as they would be in group housing indoors. 

Farrowing can take place in a farrowing crate or outdoor systems. In both methods, the pregnant sow is given her own space without the interruption of another sow.

Farrowing crates prevent the sow from turning and reduce the risk of her crushing her piglets. In addition to keeping the sow in one area, the crates also have a 'creep' plate which is heated and attracts the piglets away from the sow reducing the chance of them becoming trapped beneath the sow. The majority of pig farms in the UK utilise farrow crates.

Outdoor farrowing systems are individual shelters that allow the sow space to create nests, the piglets are restricted to a small space outside the shelter for the first two weeks. 

The final stage in pig production is growing or finishing. Pigs born outdoors are brought indoors after a weaning period. In the UK, only 3% of pigs spend their whole life outdoors. (RSPCA)

Livestock Genetics

Livestock populations provide people with a variety of products and services, including meat, milk, eggs, fibre and draught power, in a wide range of environments. This diversity of function is only possible because of the diversity of their genetic make-up.

Alternatives to antibiotics in livestock production

The ability of an animal to be resilient to diseases is dependent upon several factors which include; immune status, husbandry practises, vaccination, genetics among others.

Basic tags

Simple meta tags.

The text to display in the title bar of a visitor's web browser when they view this page. This meta tag may also be used as the title of the page when a visitor bookmarks or favorites this page, or as the page title in a search engine result. It is common to append '[site:name]' to the end of this, so the site's name is automatically added. It is recommended that the title is no greater than 55 - 65 characters long, including spaces.
A brief and concise summary of the page's content, preferably 150 characters or less. Where as the description meta tag may be used by search engines to display a snippet about the page in search results, the abstract tag may be used to archive a summary about the page. This meta tag is no longer supported by major search engines.
Advanced

Meta tags that might not be needed by many sites.

Geo-spatial information in 'latitude; longitude' format, e.g. '50.167958; -97.133185'; see Wikipedia for details.

The URL of an image which should represent the content. The image must be at least 200 x 200 pixels in size; 600 x 316 pixels is a recommended minimum size, and for best results use an image least 1200 x 630 pixels in size. Supports PNG, JPEG and GIF formats. Should not be used if og:image:url is used. Note: if multiple images are added many services (e.g. Facebook) will default to the largest image, not specifically the first one. Multiple values may be used, separated by a comma. Note: Tokens that return multiple values will be handled automatically. This will be able to extract the URL from an image field if the field is configured properly.
The URL of an video which should represent the content. For best results use a source that is at least 1200 x 630 pixels in size, but at least 600 x 316 pixels is a recommended minimum. Object types supported include video.episode, video.movie, video.other, and video.tv_show. Multiple values may be used, separated by a comma. Note: Tokens that return multiple values will be handled automatically.
A alternative version of og:image and has exactly the same requirements; only one needs to be used. Multiple values may be used, separated by a comma. Note: Tokens that return multiple values will be handled automatically. This will be able to extract the URL from an image field if the field is configured properly.
The secure URL (HTTPS) of an image which should represent the content. The image must be at least 200 x 200 pixels in size; 600 x 316 pixels is a recommended minimum size, and for best results use an image least 1200 x 630 pixels in size.

The type of image referenced above. Should be either 'image/gif' for a GIF image, 'image/jpeg' for a JPG/JPEG image, or 'image/png' for a PNG image. Note: there should be one value for each image, and having more than there are images may cause problems.
The date this content was last modified, with an optional time value. Needs to be in ISO 8601 format. Can be the same as the 'Article modification date' tag.
Links an article to an author's Facebook profile, should be either URLs to the author's profile page or their Facebook profile IDs. Multiple values may be used, separated by a comma. Note: Tokens that return multiple values will be handled automatically.

Twitter Cards

A set of meta tags specially for controlling the summaries displayed when content is shared on Twitter.

Notes:
  • no other fields are required for a Summary card
  • Photo card requires the 'image' field
  • Media player card requires the 'title', 'description', 'media player URL', 'media player width', 'media player height' and 'image' fields,
  • Summary Card with Large Image card requires the 'Summary' field and the 'image' field,
  • Gallery Card requires all the 'Gallery Image' fields,
  • App Card requires the 'iPhone app ID' field, the 'iPad app ID' field and the 'Google Play app ID' field,
  • Product Card requires the 'description' field, the 'image' field, the 'Label 1' field, the 'Data 1' field, the 'Label 2' field and the 'Data 2' field.
A description that concisely summarizes the content of the page, as appropriate for presentation within a Tweet. Do not re-use the title text as the description, or use this field to describe the general services provided by the website. The string will be truncated, by Twitter, at the word to 200 characters.
By default Twitter tracks visitors when a tweet is embedded on a page using the official APIs. Setting this to 'on' will stop Twitter from tracking visitors.
The URL to a unique image representing the content of the page. Do not use a generic image such as your website logo, author photo, or other image that spans multiple pages. Images larger than 120x120px will be resized and cropped square based on longest dimension. Images smaller than 60x60px will not be shown. If the 'type' is set to Photo then the image must be at least 280x150px. This will be able to extract the URL from an image field if the field is configured properly.
The MIME type for the media contained in the stream URL, as defined by RFC 4337.
