AbstractFull Text

Different issues associated to post-cervical artificial insemination (PCAI) in sows such as bleeding, suppuration, or semen backflow and their impact on the farm reproductive parameters were evaluated. PCAI of 1991 Large White × Landrace multiparous sows were realised in a commercial pig farm in...

AbstractFull Text

The aim of this study was to determine the effect of temperature on the day of artificial insemination (AI) on fertility, and to study how climate zone of the farm may modify this effect, in two breeds of sheep that are reared on the Iberian Peninsula on four farms located within one of three...

Abstract

This study assessed the effects of management factors and weather at artificial insemination (AI) on fertility rate in the Florida goat breed based on 7621 artificial inseminations from 47 farms in Spain. Overall, fertility rate was 55%. Farm (P<0.0001), month (P<0.01), number of previous kiddings (P<0.05), milk production at AI (P<0.05), interval between last kidding and AI (P<0.0001), the person responsible for selecting animals for AI (P<0.05), progestagen dose (P<0.001), eCG dose (P<0.0001), sperm dose (P<0.05), site of insemination (P<0.001), incidences at AI (P<0.0001), fulfillment of AI timing schedule (P<0.0001), buck (P<0.0001), and technician (P<0.001) had a significant effect on fertility rate. Mean and maximum temperatures (T) (P<0.001) and solar radiation (SR) on the day of AI differed significantly between does that became pregnant and those that did not. After meteorological data were converted to categorical variables as deciles, the proportions of does that became pregnant were significantly higher among inseminations that were performed when...

Abstract

A total number of 1092 artificial inseminations (AIs) performed from March to May were documented over four consecutive years on 10 Payoya goat farms (36° N) and 19,392 AIs on 102 Rasa Aragonesa sheep farms (41° N) over 10 years. Mean, maximum, and minimum ambient temperatures, mean relative...

Abstract

The present study was conducted to determine the effect of different factors on pregnancy rate after artificial insemination (AI) with refrigerated and frozen semen in Payoya goats reared under commercial farm conditions. A total of 820 goats, belonging to 10 farms, was used. The total number of...

Abstract

Acute puerperal metritis (APM) and clinical metritis (CM) are uterine diseases frequently diagnosed in dairy cows. These diseases are responsible for important economic loss because of their effect not only on reproductive performance but also on milk production. The objective of this study was to...

Abstract

Sperm quality was assessed in normozoospermic human (n=10) and Spanish breed stallion (n=10) after sperm fractionation during ejaculation. The first ejaculated fraction was separated from the second. A third sample was reconstituted using equivalent proportion of both fractions (RAW). Fraction 1,...

Abstract

This study was carried out to examine the impact of several climate variables on the pregnancy rate after cervical artificial insemination (AI) of Rasa Aragonesa ewes. Data were derived from 8,977 inseminations in 76 well-managed flocks performed during the first month of the breeding season (July...
