How do you tell the difference between a single and a double ridge sheep? 5

The difference between single cashmere double sheep and double cashmere double sheep.

1. Single cashmere double sheep is that there is no chorion between the two amniotic cavities; Whereas, the double chorionic sheep is a double chorionic membrane, and there are two layers of chorionic membrane between the two amniotic cavities.

2. Single cashmere double sheep is a placenta with two children, which is commonly known as identical twins, and their sex is the same; The double cashmere double sheep is two placentas, that is, the two babies are in their own amniotic cavity, which is commonly known as fraternal twins, and the sex of the two fetuses may be different.

3. Both single cashmere and double sheep are monozygotic twins; The double cashmere double sheep is not necessarily a dizygotic twin, generally most of them are two fertilized eggs, two embryos, but there is also a fertilized egg, two embryos.

The single ridge and the double ridge actually say that the back is wide or narrow... Generally, the back of the old version of the German pastor is relatively wide... The whole dog is relatively strong and powerful The new version of the SV body pays more attention to the curve, and the back is not as wide as the old version of the German Mu

The most important thing in twin pregnancy is to determine the number of chorionic sacs and amniotic sacs in the first trimester.

The wings are different sometimes and that's it.

The so-called single ridge is the size of the fan. The back is called narrow, and the double ridge is that the fan is small and the back is wide. The arched back of the single ridge is powerful.

Growth, meat yield, and weight are not the same as those of adult sheep, and the double back of adult sheep is about 15-20 pounds heavier than that of a single back!

The growth rate, the meat yield and the reproduction rate are obviously different.

The differences between single cashmere single sheep and single cashmere double sheep are as follows:

Single-cashmere single sheep and single-cashmere double sheep are both types of twin babies, and the key difference between the two is that the number of amniotic cavities is not the same.

The single cashmere single sheep twins use the same embryo, and they are in the same amniotic cavity, and there is no partition in the middle. Although the single cashmere twin twins also use the same embryo, the two fetals grow and develop in separate amniotic cavities.

To put it simply, a single cashmere sheep is two people living in a single room, and a single cashmere double sheep is two people living in a two-bedroom room with one person in one room.

In addition to the difference in the number of amniotic cavities, the risks that may be encountered during pregnancy are also different for single and double sheep.

What are the risks of single cashmere single sheep:

In the second half of pregnancy, it is very easy to have the umbilical cord entanglement and tying of the two fetal babies, and sometimes the two fetal babies will squeeze each other, resulting in the risk of oxygen production or nutrient deficiency of the other party.

What are the risks of single cashmere double sheep:

Because of the separation of the amniotic cavity, the twin babies with single cashmere double sheep are not easy to have 2 fetuses with neck wrapping or tying, but they are most likely to have twin intravenous injection syndrome, the selective growth and development of twins is limited and their twins have no cardiac coding sequence syndrome and other complications, and the incidence of the disease reaches 25%-30%.

Generally speaking, single back and double back are colloquial names. A single spine is an adult dog with a more protruding vertebrae on the back. The sides are thin and narrow.

The opposite is true for a double back, which is thick and looks strong. This is also a manifestation of chromosomal recessiveness. Specifically, which ones are good, each has its own advantages, so I won't list them all.

Well, according to personal preferences. The dozen or so purebred German Shepherds I breed are all double-backed.

Single-backed, double-backed are all her farts. See how you feed it, thank you.

The old herdsmen can distinguish the sheep by eye, and the novice can mark the sheep, such as paint, and different flocks are painted with different colors.

If it is a ewe and a lamb, you can use a marker pen to mark the horns of the ewes with numbers, and tie strips of cloth with the corresponding numbers to the little hooves of the lambs. Remember to remove the strip of cloth when the lamb grows up, otherwise the lamb will be strangled.

Pigments are very effective.

1. The risk probability is differentThe risk of single cashmere sheep is higher than that of single cashmere double sheep, and single cashmere double sheep can grow in their respective amniotic cavities, ** avoiding the possibility of twin transfusion syndrome and fetal abortion.

2. Different physiological structures:Single-cashmere single sheep is two fetuses sharing a placenta and amniotic cavity, while single-cashmere double sheep also use the same placenta, but the two fetuses develop separately in their respective amniotic cavities.

3. The reasons for the formation are differentThe reason for the formation of single cashmere double sheep is mainly due to the different development time of the placenta and fetal membranes, and the cell mass has differentiated into chorionia within 4 to 8 days after fertilization, and then forms the amniotic sac. Regardless of single cashmere single sheep and single cashmere double sheep, during pregnancy must do a good job of prenatal examination, if the doctor recommends that you terminate the pregnancy, do not have to be too entangled, to deal with it as soon as possible, so as to ensure the safety of pregnant women.

There is a single-ridge German Mu and a double-ridged German Mu, that is, according to the shape of the back, half of the single-ridge German Mu is common, and the double-ridged German Mu can clearly feel the back is two ridges. There is no good or bad difference, except that in appearance, the double-ridged German pastor looks a little wider on the back. Nowadays, most of the German pastors are East Germany and West Germany, long hair and short hair, flat back and arched back, and few people introduce others to say that their German pastor is a single-ridged German pastor or a double-ridged German pastor.

There is no such thing as a single ridge or a double ridge!

There is no such difference, but there is no such thing as good or bad.
