[心得] 結紮對於狗健康的影響
本文的主旨是 結紮對於狗健康的影響
因為這邊是"狗版"
不是"環境衛生"也不是 "政令宣導"版
更別全盤相信我 或 指我不專業 因為這邊不是"獸醫"版
也不用批評我反政府政策
如果今天狂犬病肆虐全台 你我親人都暴露在狂犬病威脅下
我會忍痛贊成把狗當作雞鴨般撲殺
以下本文開始
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
我在google 學術 打入關鍵字 Gonadectomy dog health (性腺切除 狗 健康)
並將文獻年份限定在最新2018年
出現如下頁面

(第五篇螢幕不夠長沒截圖到)
我擷取前五個文章的摘要及重要內容與大家分享
英文傷眼 可直接看中文 中文翻譯應屬正確貼近原文 有翻譯錯誤亦可指正
第一篇
Association of cancer-related mortality, age and gonadectomy in golden
retriever dogs at a veterinary academic center (1989-2016)
https://doi.org/10.1371/journal.pone.0192578
摘要本文
There was no significant difference in the proportion of intact males and
castrated males dying of cancer (p = 0.43) but a greater proportion of spayed
females died of cancer compared to intact females (p = 0.001). Intact female dogs had shorter life spans than spayed female dogs (p<0.0001),
but there were no differences between intact and castrated males.
公狗死於癌症與結紮無顯著差異(p = 0.43),但結紮母狗死於癌症比例較高。未結紮母
狗壽命比結紮的短(p <0.0001),但公狗結紮與壽命無關
第二篇
Aggression toward Familiar People, Strangers, and Conspecifics in
Gonadectomized and Intact Dogs
https://doi.org/10.3389/fvets.2018.00018
摘要本文
However, there was a low but significant increase in the odds of moderate or
severe aggression toward strangers for all gonadectomized dogs compared with
intact dogs, but this effect was driven entirely by data for dogs
gonadectomized at 7–12 months of age, which were 26% more likely to
demonstrate aggression toward strangers. Given the increasing evidence of significant negative health effects of
gonadectomy, there is an urgent need to systematically examine other means of
preventing unwanted procreation, such as vasectomy and hysterectomy.
雖然狗嚴重攻擊陌生人機率低 但結紮將使狗對陌生人的中度及嚴重攻擊性增加,越來越
多證據顯示結紮對狗健康有負面影響
第三篇
The effect of age, sex and gonadectomy on dogs’ use of spatial navigation
strategies
https://doi.org/10.1016/j.applanim.2018.05.010
摘要本文
In addition to increasing our knowledge about navigation, these results
highlight effects of sex and ovariectomy on dog cognition, with potentially
important implications regarding the management of dogs in different fields.
性和卵巢將對狗的空間認知很有關係 (這篇內容很專 我只能大略理解結紮會讓狗比較沒
有方向感,而這方向感似乎是由觀察周遭事物得到??)
第四篇
Population Control in Small Animals
https://doi.org/10.1016/j.cvsm.2018.02.013
摘要本文1
Optimal age for ovariohysterectomy (OHE) or castration has not been defined
in the scientific literature. Bitches and queens are significantly less
likely to develop mammary neoplasia, which has a high incidence and
potentially high morbidity and mortality, if spayed when young. There is no
compelling reason to castrate male dogs when young unless it is needed to
control reproductive behaviors or prevent indiscriminate breeding.
結紮的最佳年齡在學術界尚無定論,母狗結紮可以降低乳腺腫瘤的發生,沒有證據支持幼
犬結紮
前言中有一句我認為蠻重要 翻出來分享
This owner may elect to wait until the dog has gone through estrus once and
spay at 12 to 18 months of age.
對於母狗降低乳腺腫瘤 作者建議 12~18個月結紮
第五篇
Behavioural risks in male dogs with minimal lifetime exposure to gonadal
hormones may complicate population-control benefits of desexing
https://doi.org/10.1371/journal.pone.0196284
摘要本文
The differences reported here between undesirable behaviours of castrated and
intact dogs were in the range of 5.04% and 12.31%, suggesting that, for some dogs, partial or complete denial of puberty may
reduce indoor urine-marking but have many other undesirable consequences.
結紮與不結紮的狗有不良行為者大約5.04~12.31%間,以結紮部分或完全的避免掉狗青春期
雖然可能降低狗標記的行為,但會產生其他不良後果
這篇前言裡面有提到
In males, it is known to increase the risk of prostate cancer but the
benefits may include removing the risk of testicular disease and other
androgen-dependent diseases, such as perineal hernias, perineal adenomas,
prostatitis and benign prostatic hyperplasia (reviewed in ref. [10]).
Additionally, gonadectomised dogs face 0.1 times the odds of developing mast
cell tumours [95% CI 0.1 to 0.2) than entire dogs [11]. Castrated males may also wander less in search of mating opportunities, an
outcome with the additional benefits of fewer traffic accidents and unwanted
litters [12]. In females, spaying was thought to reduce the risk of mammary neoplasia [13]
but a recent systematic review described evidence for this association as
being only weak [14].
公狗結紮會增加前列腺癌的風險,但可消除睾丸疾病和其他雄激素依賴性疾病。結紮的狗
容易得到肥大細胞腫瘤,結紮的公狗在尋找母狗的時間較少,不易被車撞。母狗結紮可降
低乳腺腫瘤的風險,但最近的報告指出先前文獻的證據很微弱。與上一篇前言中有矛盾
In summary, the effects of castration on dog behaviour have not been
exhaustively investigated, and relevant studies sometimes produce conflicting
results. The current study examines data from the owners of male dogs to
explore relationships between various canine behavioural attributes, as
reported through C-BARQ, and castration considering both AAC and percentage
lifetime exposure to gonadal hormones (PLGH) as factors. Clearly, AAC and
PLGH are related but the latter indicates how long the dog has lived with
gonadal hormones until the age of castration, and can reveal the influence of
gonadal hormones on behaviour after puberty, reflecting the role of
circulating hormones in the normal behavioural biology of dogs.
巴拉巴拉巴拉專業名詞看不懂,最後結論是”性腺激素對於青春期後的狗行為是有影
響的" 但是好影響或壞影響請自己看內文 或 參照前幾篇的內容
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
至於本文的結論 我想就把他留白 讓聰明的客官自行定論吧!
如果硬要蓋我反政府 找理由不結紮的大帽子
我只能重申 如果為了公眾利益 需要犧牲狗兒健康 我同意 但要求人的態度呢?
