| I am slowly learning that as in any situation, the best offence is a good defence. You can defend yourself from the surprise of dealing with a bad situation by being prepared well in advance. For the past six weeks, we've talked about being prepared for an emergency - now we're going to discuss being prepared for what happens if the emergency is too much to deal with. There are many reasons in a horse's lifetime why you may have to consider having him put down. Mainly though, they can be lumped into two categories - serious injury or illness and chronic degeneration. Serious injuries can be one of the hardest to deal with because so much is thrown at us when we are emotionally stressed. To have a good "offence", plan your strategies out in advance. Know where your closest veterinary clinic is in terms of both miles and minutes. Talk to the vets that practice there and find out what types of equine surgical emergencies they are prepared to deal with. Some clinic are not equipped to deal with a colic, or a Caesarean section on a foaling mare, or broken limbs. Some are partially equipped, and so can stabilize your horse for a trip to the nearest clinic that is able to help your horse. Prince George for instance has an equine vet clinic but not having used them I am unsure what services they offer. I know there is a very good clinic between Red Deer and Innisfail on Highway 2 in Alberta, and there may be others in the Lower Mainland. To get to either of those, we are looking at a minimum of 13 hours driving time before reaching our destination - the bottom line here is whether or not your horse will make it. You have several issues to look about that topic in itself. Will your horse survive the trip? Will he be in pain too immeasurable to put him through? Is he at considerable risk to do more damage to himself? All of those must factor in to the decision to haul or to stay home. More next week. |

Some genes are dominant, meaning that even with only one copy of the gene present, their colour will come through. The tobiano pinto gene is one such gene - hence the desire for breeding pintos with homozygous tobiano genes. A homozygous tobiano will always throw a tobiano gene, and therefore 100% of their offspring will be pintos. The red gene is not dominant as it can be hidden under black - the black gene is dominant over the red gene. The grey gene is dominant, as are dun and roan. The cream dilute gene is considered an intermediare gene - it is partially dominant (dilutes the base colour in its heterozygous form, but not to complete white unless in homozygous form) except when crossed on a black gene, when it can be hidden altogether. A dominant gene simply means that even with only one copy of the gene, it will be expressed. There are some hard and fast rules in colour genetics, though not many. Take for instance, your standard sorrel or chestnut. These horses have two copies of the red gene - they do not carry black genes, dilute genes, or grey genes, just red. No matter what colour horse you breed them to, they will always pass on a red gene - and that means that when crossing sorrel to sorrel, you can ONLY get sorrel. There is no way two sorrels can produce anything else. When dealing with the black and red genes, if there is another gene called agouti present, then the black is restricted to the points (mane, tail, legs). A red horse can carry agouti and not have it expressed - they have no black gene to restrict - but they can then pass the agouti gene to a foal if the other parent throws a black gene. This is why when people advertise that their stallion is homozygous for the black gene, they can't make the claim that he will throw only black foals - some of them will be bays, etc - but they can claim that he will NOT throw sorrel or chestnut as his black gene will mask the red gene to some extent. Next week, onto my favourite colour gene - the cream dilutes! |
