【摘要】：種公雞攜帶病原體傳遞給后代的問(wèn)題由來(lái)已久,作為垂直傳播的一個(gè)途徑其危害不容小視,可致雛雞死亡率高、后代生長(zhǎng)不良、疫病代代相傳、生產(chǎn)力低下,甚至給環(huán)境保護(hù)、可持續(xù)發(fā)展帶來(lái)挑戰(zhàn)。試驗(yàn)對(duì)新研發(fā)的一種精液保護(hù)劑進(jìn)行了評(píng)價(jià)。1通過(guò)兩種稀釋比例、經(jīng)過(guò)4個(gè)不同時(shí)間點(diǎn),檢測(cè)了新型精液保護(hù)劑對(duì)大腸桿菌、金黃色葡萄球菌、綠膿桿菌的殺滅率,結(jié)果表明,新型精液保護(hù)劑對(duì)三種細(xì)菌的殺滅率分別達(dá)到99.99%、99.99%和100.00%;2對(duì)加入新型精液保護(hù)劑后的種雞精液在不同時(shí)間點(diǎn)進(jìn)行精子活力測(cè)定,結(jié)果各時(shí)間點(diǎn)的精子活力均明顯高于空白試驗(yàn)組。綜合表明,該新型精液保護(hù)劑不但可殺滅精液中的病原體,而且可以提高精子活力。
[Abstract]:The problem of carrying pathogens to future generations of breeding roosters has a long history. As a way of vertical transmission, its harm should not be underestimated, which can lead to high mortality of chicks, poor growth of offspring, transmission of epidemic diseases from generation to generation, low productivity and even environmental protection. Sustainable development poses challenges. A newly developed semen protectant was evaluated. 1 the killing rate of the new semen protectant against Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa was detected by two dilution ratios and four different time points. The results showed that the killing rates of the new semen protectants against the three bacteria were 99.99%, 99.99% and 100.00%, respectively. (2) the sperm motility of breeding chicken semen added with new semen protective agent was measured at different time points. The results showed that the sperm motility at each time point was significantly higher than that in the blank test group. The results showed that the new semen protectant could not only kill the pathogen in semen, but also improve sperm motility.
