統計當然有 只有算月和年度
每月分娩率及產仔頭數 會因季節和冷精配種量還有疾病因素 而改變
有記錄統計  ...

不知道你的紀錄表是如何設計的
紀錄表的設計最好是一目了然
由你談你場內的紀錄可知,顯然需要再修正
否則看不出問題所在
做紀錄無法發揮預警作用,那這紀錄.....................

記錄表 自己想的 別人看應該會 霧煞煞
有專業設計的記錄表 可參考？如果能修正並能找出問題 很樂意改進
今年要重改母豬設備 就是有找到問題  9～11月配種的授胎率 分娩率都會比較差

陳主委說養豬業者心態沒有改變
應該不包括你
經營任何事業,要放開心胸,進步比較快

這讓我想起 羅登源 羅老師第一次見面問我的一句話
你養豬是為了什麼？我毫不猶豫回答 當然是要賺錢
現在認真思考後 那時只回答要賺錢 這樣不夠
上一代辛苦打拚下來的 不應只是守成

創業維艱,收成不易

精蟲凝集現象一般低於20%勿需擔心

Abstract


The aim of this study was to examine the incidence of sperm agglutinations and their relationships with sperm quality and fertility. Semen samples of 40 boars of an AI-station were investigated. Nineteen of the 40 investigated boars showed a constantly low (< 10% agglutinated sperm), 3 an intermediate (10-20%) and 6 boars a high level (> 20%) of agglutination in raw semen. The degree of agglutination in sperm samples of 12 boars varied distinctly during the investigation period. During summer more (P < 0.05) agglutinated sperm were observed (11.0 +/- 11.6%) than during winter (6.2 +/- 7.3%). There was no association between bacterial contamination and incidence of agglutinations (P > 0.05). After dilution in extender the percentage of agglutinated sperm decreased from 6.2 +/- 7.3% to 1.1 +/- 1.4% (P < 0.0001). Twenty-four hours after dilution the percentage of progressively motile sperm was 7.4% lower (P < 0.05) in ejaculates with an initially high degree of agglutination (> 20% agglutinated sperm) compared to samples with an initially low degree of agglutinated sperm (< 10%). Plasma membrane integrity, mitochondrial membrane potential, acrosome reaction and chromatin structure were independent (P > 0.05) from the level of agglutination. Fertility data did not differ (P > 0.05) between boars with low and high numbers of agglutinated sperm in raw semen. The results show that there are individual, ejaculatory and seasonal variations in the incidence and degree of agglutination. Agglutinations have a negative effect on motility of sperm and disappear to a large extent after dilution in sperm extender. They have no negative consequences on fertility.
