“…In our results, no positive effect of crossbreeding on the number of piglets born live and weaned was noted. Improving reproductive performance is one of the reasons for the use of crossbreed sows (Vanderhaeghe et al, 2010). A higher number of live born piglets may reflect individual potential in the reproductive physiology of the breeds and crossbreeds in terms of not only high uterus capacity but also more resistance to environmental conditions such as climatic conditions, nutrition, etc.…”

Abstract. The aim of the study was to identify the detailed impact of the season, parity and breed on reproductive performance of sows. The experimental material consisted of 2100 sows, in 3 breed variants: 700 PL, 700 PLW, 700 crossbreeds PL × PLW. Sows were observed until parity 5. In the context of the breed, depending on the order of parity groups of 140 sows were isolated. Then, sows were divided in terms of farrowing season into subgroups numbering 35 sows. At the age of 8 months gilts were allocated for reproduction performance. The highest seasonal impact was noted for piglet birth weight (P ≤ 0.01). Parity had less effect only on the number of piglets weaned (P ≤ 0.05). Breed influenced to a lesser extent the number of piglets born live and weaned (P ≤ 0.05), while birth and weaning weight had greater importance for piglets (P ≤ 0.01). The interaction between the studied factors was also observed. The impact of season, parity and breed interdependence on the number of piglets born live were confirmed statistically (P ≤ 0.05). The analysis of piglet birth weight allowed the stronger interaction effect of parity × breed on this parameter to be noted (P ≤ 0.01). The analysis of variance for piglet weaning weight confirmed strong relations between all tested factors (P ≤ 0.01). Our study has shown that reproductive parameters can be strongly affected by season and parity. In addition, it must be emphasized that the impact of these factors was different for the studied breeds of sows.

“…Producers striving to increase productivity use not only pure breed but also crossbreed sows ( Vanderhaeghe et al, 2010). The genetic potential of pigs has drastically changed over the last 50 years, affecting the improvement of production parameters (Brown-Brandt et al, 2004).…”

“…Die durchschnittlichen Tagestempera turen lagen im Mai rund 0.7 °C, im Juni 1.8 °C und im Juli mehr als 3 °C über den durchschnittlichen Tages temperaturen der Vergleichsjahre 1981(Meteo Schweiz, 2015aMeteoSchweiz, 2015b). Obwohl in dieser Studie nicht näher untersucht, gelten Hitzestress und hohe Umgebungstemperaturen als Risikofaktor für PPDS (Quiniou und Noblet, 1999;Maes et al, 2010;Vanderhaeghe et al, 2010b). Obwohl eine grosse Palet te von Interventionsmassnahmen für die Betreuung zur Verfügung stand, führte die tierärztliche Bestandesbe treuung nicht in jedem Fall zu einer Senkung der PPDSPrävalenz.…”

The Postpartum Dysgalaktie Syndrome (PPDS) also known as metritis agalactia mastitis (MMA), is considered the most common disease of the sow after farrowing. The reasons for PPDS are multifactorial and are to be found in the areas of management and hygiene, feeding, water supply and animal specific factors such as body condition and age of the sows. In this study a veterinary herd health management was carried out in 28 pig farms with PPDS, with the aim to reduce the PPDS prevalence and animal treatment incidence (TI). In 20 of 28 problem farms the PPDS-prevalence could be decreased from 37.4% (± 21.8%) to 24.5% (± 14.1%). The TI was not significantly reduced. The most effective procedures to reduce the PPDS-prevalence were the use of a prepartal transition feed, optimizing the PPDSdiagnostic and the use of nonsteroidal antiinflammatory drugs (NSAID) and oxytocin in the PPDS-treatment.

“…The mean number of stillborn pigs per litter in the present study was below the 3-8% of all pigs born in highly prolific sows (commercial lines derived from Large White x Landrance) (Borges et al 2005, Vanderhaeghe et al 2010. The highest number of stillborn pigs per litter occurred in spring and winter, which indicates that thermal stress was not associated with this reproductive problem.…”

ABSTRACT. The objective of this study was to analyse the reproductive performance of hybrid (Yorkshire x Landrace) gilts/ sows in relation to temperature-humidity index (THI) at artificial insemination (AI), season of AI, occurrence of estrus >8 d postweaning, repeated estrus, insemination technique (cervical, CAI or post-cervical, PCAI) and parity. Data included 8851 reproductive records (1771 for gilts and 7080 for sows) from a pig farm in a sub-tropical zone (THI ranged from 72.9 in January to 81.8 in June). A decrease in pregnancy rate (PR, 89.8 vs 93.0%; P<0.01) and a tendency to decline farrowing rate (FR, 87.9 vs 90.3%; P=0.07) following AI during high THI (>82), compared to AI at <74 THI were observed. The spring and summer season were associated with decreased (P<0.01) PR compared with fall and winter (90.0% vs 93.0%). Likewise, FR decreased in spring and summer compared to fall and winter (88.5% vs. 90.9%). FR was higher (P<0.01) in non-repeat breeders compared with that of repeat-breeders (90.3% vs 76.2%). Litter size increased (P<0.01) from 10.8 ± 3.2 to 11.1 ± 3.1 pigs when the interval from weaning to estrus was >8 d. The insemination technique did not affect PR and FR but the litter size decreased (P<0.05) from 11.3 ± 3.0 to 11.1 ± 2.9 pigs when PCAI was used compared to CAI. This study reaffirms the negative effects of the hot season on reproductive performance of gilts/sows, although thermal stress at AI did not cause foetal losses. Also, there is no advantage in using the PCAI as compared to the CAI in gilts/sows with high numbers of sperm cells per AI.
