This week is arguably the biggest show of Livestock in the UK. There will be many fine animals on display. Some will have be conceived naturally and delivered perfectly normally other will be embryo transfer and will have been caesered and of course a whole range in between.
With some in the veterinary profession raising questions about the breeding of among others dogs which cannot breath correctly due to breeding or even have no ability to give birth naturally! All bred by the supposedly most intelligent species on Earth, us!
This brings me to the cattle side of things and whether some are overstepping the welfare of livestock.
Let me explain a situation that may arise.
Pedigree breeder has a number of embryos and wishes to put into donor 18 month old heifers. Of course these embryos are only from the top performing genetic lines for LWG, muscle depth, but not for ease of calving.
So the embryos are 5 days old and are implanted into a batch of these maiden heifers. These maiden heifers are of course not the same breed they are limousines and the embryos are from Charolais. Again the genetics of these maiden heifers is not necessarily from and easy calving line.
So so save the cost of getting the transfer guy out twice 20 heifers get implanted at the same time.
Of course 4 months later and after they have run with a bill for a spell they get scanned. A good number have held to embryos, 12, and all the other heifers are in calf, result!
Anyway preps get under way for the calving and it is decided that to ensure the 12 heifers calf easily and hence improve the ease of calving score for EBVs they will be induced at 272 day.
So they get the Jag. Funnily enough half of them calf albeit with the usual problems of retained cleansing, slow calves and low colostrum production. The calves were a good size though. 3 others the waters break but there is no way the calves are coming out even with the aid. Vet appears when the 3 are lined up and caesered. 2 of the calves are really stressed and are touch and go and one is dead. One of the heifers is no looking to great and goes on to die. The other three give birth 1 with the aid and the other 2 caesered at more than 286 days.
Now this is of course a fictional tale.
So from an animal welfare point of view is this practice acceptable?
