So yellow grass is increased oestrogen but worse for tupping?

I remember hearing some time ago at a grazing meeting not to graze covers right down at tupping as there may be toxins lower in the sward which may result in reduced conception. Best to leave some and come back after the pregnancy is implanted if you want to take it right down.
OK thanks. The camera makes it look more yellow than it is anyway but something to keep an eye out for if scanning is low.

There.
Reduced your yellow grass content
You'll have a much better lambing % now
. Simples! (If only it were that simple)
[emoji23] Good man. The girls are grateful

How to calculate cattle weight without needing a scale!
We often find ourselves in the situation we need to know the weight of an animal, whether it's to calculate a ration, a dose or to determine if the heifers are ready for service. However, having a scale on the field is a privilege only some ranchers have.
Faced with that situation several times, ranchers resort to estimate the weight only by looking at the animal, however, this can lead to many errors, such as inseminating a heifer ahead of time, forcing it to have complications in labor and pups weaker or subdosing or overdosing animals with some medicine. This is because many don't know that to know the estimated weight of a bovine we only need tape measure.
The zoometric measures of animals are very well connected with weight and therefore it is possible to use them to estimate weight through these measures. Two basic zoometric measures that can be used are the chest perimeter (PT) and body length (LC). The length of the body is measured from tip of the buttock to the tip of the shoulder (distance between a and b in the graphic, and the chest perimeter for this is measured by the chest to the height immediately following the scapula.
Once these two measurements are obtained in centimeters we use the next PT x PT x LC / 10838 equation (adapted from Schaeffer's formula) and will result in the weight in kg of the animal. This can be used for both South American vaccines, sheep, goats and camelids. For example, in case of a cow with 177 cm chest perimeter and body length of 198 cm, the formula would be 177 x 177 x 198/10838, its weight would be 577 kg, And in the case of a sheep with a chest perimeter of 89 cm and a body length of 76 cm, the formula would be 89 x 89 x 76/10838, its weight would be 55 kg ...

I've got a calibrated weigh tape which measures round the chest only which I used to keep an eye on the three heifers we bucket reared. My impression was that it was reasonably accurate up to a point but when they got nearer mature size it wasn't quite as good.I think someone asked ?

Have been sent this from the local cooperative I sell my beef to, sounds really good to me ...Regenerative the highest score

Wow, well that changes a bit from thé europ grid!
I think it's a grand Idea. Although I don't agréé on being marked down for crossbreeds.
What coopérative are you selling too?
I sell through CQLP which is a local cooperative they deal with Conventional & Organic stock. They sent this information through and are asking for feedback & if we want to express a interest.
Tell us what's happening ?
what do the fences consist of .?Shouldn't laugh
we've all been there.If they keep getting out just put a fence around them where they end up.
Keep them fat and lazy and they won't bother to jump so much
I usually just have two strands up which they just walk under. But recently I’ve been putting 2 lines up so a double strand and then a single strange on a separate run, thinking they would more chance of getting a shock. But I watched them today just walk straight through it. My fencer is a voss 5j which gives off a hell of a whack but the shocks are to slow and there’s to much of a delay between shocks. They have plenty of grass but they always want what’s the other side of my wire.... what’s the problem?
Was hoping to hit these rushes hard with small pens but they won’t stay in them

Nor do I agree about marking down crossbreeds
