16快速生长小母猪较早进行人工授精后对繁殖性能的影响显示文摘本试验的目的是研究提早具有较快生长速度(GR)的小母猪的配种时间,是否会降低其头3胎的繁殖性能、提高其1~3胎的淘汰率。试验选用568头Camborough 22小母猪,按配种时的体重和年龄分成3组:第一组(G1组)164头,生长速度高于等于700g/d,配种年龄低于210d;第二组(G2)165头,生长速度高于等于700g/d,配种年龄高于210d;第三组(G3)239头,生长速度低于700g/d,配种年龄高于210d。所有试验小母猪从150d起采取自由采食,并于其第二个或随后的发情期配种。第一胎,G2组小母猪的平均产仔数多于其它组(P<0.05)。然而,在对三胎产仔数进行分析后表明,各组小母猪在总产仔数(分别为11.6、12.3和11.7头)、分娩率(分别为87.1%、88.7%和和89.8%)和淘汰率(分别为30.2%、25.3%和28.2%)上没有显著差异(P>0.05)。因此,日龄在185~210d、体重为127kg的小母猪,可以在其第二个或随后的发情期中给予配种,且配种不会影响其头3胎的生产性能。于古月 Rafael Kummer mari Lourdes Bernardi Ivo Wentz Fernando Pandolfo Bortolozzo 2007国外畜牧学(猪与禽)2007,,4:0
17In vitro performance and in vivo fertility of antibiotic-free preserved boar semen stored at 5℃显示文摘Background: Hypothermic preservation of boar semen is considered a potential method for omitting antibiotics from insemination doses, thereby contributing to the global antibiotic resistance defence strategy. The main challenges are chilling injury to spermatozoa and bacterial growth during semen storage leading to reduced fertility.Objectives: To examine chilling injury and the number and type of bacteria in boar semen stored at 5 ℃ in the absence of antibiotics, and to assess the applicability of hypothermic semen storage under field conditions.Material and methods: Boar ejaculates were extended with AndroStar~? Premium, stored at 17 ℃ with and at 5 ℃ without antibiotics and tested for functional sperm parameters by flow cytometry. Raw semen and extended samples were investigated bacteriologically. Fertility was evaluated after once-daily inseminations of 194 sows in a field study.Results: Lethal sperm damage assessed by motility and membrane integrity was low throughout storage in both experimental groups. Sublethal chilling effects based on the decrease of viable spermatozoa with low membrane fluidity were higher(P < 0.05) up until 72 h in sperm stored at 5 ℃ compared to 17 ℃ but did not differ after 144 h.After 72 h, incubation in capacitating medium for 60 min induced a similar decrease in viable sperm with high mitochondria membrane potential and low cytosolic calcium in both groups. In semen stored at 5 ℃, bacteria counts were below 103 CFU/mL and the bacteria spectrum was similar to that of raw semen. In 88% of 34 boars,cooled semen fulfilled the requirements for insemination. Fertility was high and did not differ(P > 0.05) between sow groups inseminated with semen stored antibiotic-free at 5 ℃ and semen stored at 17 ℃ with antibiotics.Conclusion: Despite subtle chilling effects and low bacterial numbers, antibiotic-free hypothermic storage of boar semen offers the possibility to reduce the use of antibiotics in pig insemination. However, strict sanitary guidelines must be maintained and further evidence of efficiency under field conditions is considered desirable.Helen Jäkel Kathi Scheinpflug Kristin Mühldorfer Rafael Gianluppi Matheus Schardong Lucca Ana Paula Gonçalves Mellagi Fernando Pandolfo Bortolozzo Dagmar Waberski 2021Journal of Animal Science and Biotechnology2021,12,1:0
