    Great information. I'm new to breeding goats and dont want to line breed as it makes me uncomfortable, but want to make sure im improving my herd at the same time. This has taught me a lot.

      Line breeding improves fitness if done properly and the bad expressions are culled.

      Hi, Chris. Thanks for the question and thanks for watching our videos. Yes, this is safe in most cases. We would encourage you to screen your livestock for various recessive genes that might cause problems. When it comes to breeding closely related animals, this is the main concern. People sometimes assume they might see birth defects, etc with close bloodlines but really we are more concerned with things like scrapie susceptible animals or dwarfism, etc.

    Hey Tim , your experience and knowledge are so admirable. Genetics is a lot to absorb initially so if you’re just starting out, how would you acquire say 5 or 6 goats. Not looking for show animals, just don’t wanna get ripped off with recessive bd genes

    • @LinessaFarms
      @LinessaFarms  2 роки тому +3

      Look for a reputable breeder in your area that raises goats (even show goats) and just tell them you are looking for good commercial/production goats. Even the show guys will sell non-registered ones. Sometimes you can get a deal on really nice animals that might not make the cut for the show ring but are very good, sound commercial animals.

    Fascinating. One point though: scrapie is not a genetic flaw it is a prion, contamination in field can last for up to 7 years. Related to mad cow disease.

    • @LinessaFarms
      @LinessaFarms  2 роки тому +1

      Scrapie susceptibility is directly linked to genetics. Scrapie is one of the most common genetic tests completed in sheep management. You are correct that it is a protein, however we can determine if an animal is susceptible based on specific genes.

    Hello Sir,
    I have a question: we are getting close to releasing our rams to our ewes for breeding. Just another 2-3 weeks more to wait as it is what’s to do in Montana climate.
    In the mean time, one of our rams is trying to hop/mate with another ram!!! He is relentless! The other ram doesn’t let it happen, but the question is: is the hopping ram homosexual?
    Could he hurt the other ram?
    What does that mean?
    How can we fix it til he is released for breeding his ewes? Is he crazy?🤦🏻‍♀️
    I’ve tried researching this, but am unable to find any directions regarding this thing... Please help!
    We are very new at having sheep and seeing this behavior in rams is disturbing 🤷🏻‍♀️ Did we get a bad ram?
    Thank you for your insight on this subject.

    • @LinessaFarms
      @LinessaFarms  2 роки тому +1

      Hello. This is normal behavior when the males are in rut. In most cases, we will keep a ewe in with our rams as a “sacrificial ewe”. More than likely, you have ewes in heat, he is smelling them, and he is a little over excited. If it’s really an issue for you, pick a ewe and put her in with them. Good question. 👍🏻

    For a small farm starting out (growing their herd) should they consider using AI instead of owning their own Male(s)? I've also heard of farms replacing their Ram/Buck each year by trading with another farm or by selling theirs and then buying another. What practice is most common?

      These would be first cousins so it would depend on their genetics. You will definitely see better health and growth by avoiding breeding close relatives.

    You cant mention "hybrid vigor" which you actually mean is called Outbreeding Enhancement, without mentioning Outbreeding Depression. Hybrid Vigor happens with other species, Outbreeding is crossing different populations of the same species.

    • @LinessaFarms
      @LinessaFarms  28 днів тому

      No, hybrid vigor (heterosis) does not require crossing different species. It commonly occurs within the same species when genetically distinct populations, breeds, or lines are crossed. Here’s a more detailed explanation:
      Hybrid Vigor in the Same Species
      • When individuals from two different breeds or lines within the same species are bred together (e.g., crossing Suffolk and Dorset sheep), their offspring may exhibit hybrid vigor. This occurs because the genetic diversity introduced can reduce the expression of harmful recessive traits and improve traits like growth, fertility, and disease resistance.
      • Examples include:
      • Crossbreeding two cattle breeds (e.g., Angus × Hereford) to produce calves with better performance.
      • Crossing different sheep breeds (e.g., Finnsheep × Texel) to improve lambing rates or meat production.
      Hybrid Vigor in Different Species
      • Hybrid vigor can also occur when crossing species (e.g., mule = horse × donkey). However, this is less common, and such hybrids are often sterile or face biological challenges (e.g., mule sterility due to chromosome mismatch).
      Summary
      Hybrid vigor is a result of genetic diversity and can happen:
      • Within the same species (e.g., crossbreeding sheep breeds).
      • Across species (e.g., horse × donkey).
      The idea that hybrid vigor strictly requires crossing different species is a misunderstanding. In practical agriculture and animal breeding, hybrid vigor most often refers to improvements seen when crossing breeds or lines within the same species.

    • @NeuKrofta
      @NeuKrofta 27 днів тому

      @LinessaFarms Hybridization is crossing different species. Hybrid Vigor is not the correct scientific term. The proper term is "Outbreeding Enhancement"
      Outbreeding causes Enhancement but it also causes Depression. That is a reduction in fitness and it's effects are more pronounced with every successive generation.
      You really need to do more homework

    Hope you're not talking about blue eyes in goats, because pretty sure blue eyes is dominant in goats.

    • @LinessaFarms
      @LinessaFarms  2 роки тому

      We used “people” and “children” in a previous video to help people understand dominant and recessive genes. In humans, red hair and blue eyes are recessive. We try not to refer to our goats as children, although we won’t judge people that do.
      Blue eyes are dominant in goats and brown eyes are recessive. If anyone in your family is trying to use goats to explain the eye color of children, we would advise a good marriage counselor. Hope this helps.

      @LinessaFarms  3 роки тому +1

      Forester, thanks for watching our videos and thanks for the comment. Yes, the purpose of the video is to teach people what different breeding methods are out there. We want customers to understand when a breeder says they are "line-breeding", in many cases this is actually inbreeding. In an effort to eliminate the stigma of using the word "inbreeding" many producers will instead use terms like "line-breeding". By many definitions, inbreeding is only used when breeding parent to child and line-breeding is breeding uncles to nieces, grandfathers to granddaughters, etc... We aren't a fan of line breeding or inbreeding and we do not use the practice here on our farm. We feel hybrid vigor/heterosis from far separated breeding stock produces the best results. Unfortunately, in the show world, many breeders are pressured to inbreed or line-breed in order to keep rigid physical features uniform between offspring. As you probably know, this has been done to dangerous levels with many animals already such as dogs. Hopefully this answer helps you out. If you need anything else, just let us know.

      That's not what line breeding is.. it might be what people say but most breeders don't know and just repeat things they hear.
      Breeding cousins is inbreeding.

    • @NeuKrofta
      @NeuKrofta 29 днів тому

      ​​you can create heterosis with Line Breeding if you know what you are doing and it can create enough genetic diversity to prevent Inbreeding Depression and actually result in Inbreeding Enhancement.
      The problem with Outbreeding is while yes it can create enhancement it can only be done once and Outbreeding Depression will get worse with every successive generation. This is why the Diary industry is panicking and milk production is plummeting no matter how much Outbreeding they do now.
