FIXED TIME INSEMINATION EFFECT ON THE CHARACTERISTICS OF HYPERPROLIFIC SOW PROGENY

After optimizing seminal doses production, the next step in reproduction is applying fixed-time insemination programs to obtain greater profitability at insemination time by reducing labour costs, number of seminal doses and increasing reproductive performance. The aim of this study was to evaluate a single fixed-time artificial insemination program (FTAI) with buselerin and measure effect on litter performance.

FIXED TIME INSEMINATION, A REALITY IN THE PROGRESS OF REPRODUCTION

After more than a decade of research, Fixed-Time Insemination (FTI) in swine is now a reality via the use of GnRH analogues (Porceptal®) that induce ovulation at a precise time, to allow high fertility and prolificacy rates from a single, well-timed AI.

LOW WATER INTAKE IN GESTATION MAY AFFECT PIGLET VIABILITY

Data from our research centre reflect large variation in individual water intake in gestating sows (2.2 to 20 L/d, 6.6 L/d average in 364 sows), and suggest that this may affect piglet survival.

VARIATION IN BOAR FERTILITY IN A MIXED SEMEN EXPERIMENT

Boars fertility can be a serious problem in pig production. Numerous studies compared the effects of individual boars on a herd or between herd levels. Unsystematic effects, however, like herd, sow, season etc. impede the accuracy of the boars’ fertility estimation.

A CASE REPORT COMPARING THE TREATMENT EFFECT OF GAMITHROMYCIN AND AMOXICILLIN IN A DANISH SOW HERD INFECTED WITH CHLAMYDOPHILA PECORUM

Chlamydophila Pecorum infections are sometimes causing reproductive problems in Danish sow herds. The case herd had reproductive problems and Chlamydophila pecorum was found in still born / fetuses. An alternative treatment, gamithromycin, was given to a smaller group of sows to compare a standard treatment with amoxicillin.

EFFECTS OF POST-PARTUM ADMINISTRATION OF DINOPROST ON SOWS HEALTH PARAMETERS

Benefit of using prostaglandins for farrowing induction is well know, post-partum use and its positive effect is less frequently discussed. Aim of the presented study was to evaluate an effect of dinoprost- Enzaprost® (Ceva) administration post-partum established based on clinical index score.

EVALUATION OF THE EFFECT OF ALTRENOGEST USE, ALONE OR IN COMBINATION WITH GONADOTROPINS, FOR GILTS’ OESTRUS SYNCHRONIZATION, ON THEIR REPRODUCTIVE PERFORMANCE IN A RUSSIAN FARM

Synchronisation of oestrus by using altrenogest was proven to be effective tool for optimal gilt management. In the present study, the effect of altrenogest (Altresyn®), alone or with gonadotropins, on gilts’ reproductive parameters was investigated, in a Russian farm.

IMPROVEMENT OF REPRODUCTIVE PERFORMANCE OF GILTS IN ONE WEEK BATCH MANAGEMENT SYSTEM BY SYNCHRONISATION OF OESTRUS

Optimal gilt management decreases variation within weekly service numbers and synchronisation of gilts by altrenogest (Altresyn®) was proven effective tool. Aim of our study was to evaluate the effect of synchronisation by altrenogest on reproductive parameters and total number of piglets born per group.

TREATMENT OF SPERM WITH MAXIPIG® BEFORE ARTIFICIAL INSEMINATION IMPROVES REPRODUCTIVE PERFORMANCES

Optimal reproductive performance is crucial for economic success in commercial pig herds. Different management strategies, such as optimized feeding strategies, hyperprolific dam lines, batch farrowing systems and extended photoperiod during the post-weaning phase, are applied in order to meet the high performance expectations of modern sow farmers. However, inevitable variations in farm conditions, such as season, infection pressure or feed ingredients can negatively impact the results of high productive genetics.

PRACTICAL USE OF PROGESTERONE TEST IN GILTS

Progesterone level can be used to determine precise moment of the reproductive cycle in gilts/ sows. Reproductive cycle has a folicular and luteal phase (high levels of progesterone). During luteal phase, progesterone level increases until day 12-14 when the luteal corpus (LC) become sensitive to PGF2α and progesterone level decreases in 48h just until the next estrus. Prepuberty gilts just around heat, have very low progesterone levels; 24-48h post-heat progesterone levels are high and remain high for at least 15-18 days indicating LC presence; finally 24-48h prior to heat progesterone levels drop very quickly again. The objective of this study is to demonstrate under field conditions how a commercial kit Ovu-check® can help establish whether a group of gilts that have not manifested consistent heat symptoms had cycled or not.

STUDY OF REPRODUCTIVE BEHAVIOR AND DESCRIPTION OF ANATOMICAL REPRODUCTIVE STRUCTURES BY ABDOMINAL ULTRASOUND IN IBERIAN SOWS

The lower prolificacy of the Iberian sows breed (IS) can be due to a lower ovulation rate, a lower percentage of fertilization, a lower implantation rate. The limited uterine space for embryo implantation would justify the greater embryonic losses.

Effect of Sperm Photostimulation in improving reproductive parameters with the use of Artificial Insemination

The use of artificial insemination (AI) with fresh semen is one of the key tools that have established the basis of exponential growth in world pork production last years. The success of the AI is basically due to that it is an economical and easy technique to use in pig farms of any size. Furthermore, the reproductive performance achieved with AI is optimal.

Relationship between ovulation rate and litter characteristics at birth

The genetic selection for increased litter size has resulted in a disproportionate increase in ovulation rate (OR). A higher OR was linearly related with decreased placental length at day 35 of pregnancy, which could inhibit foetal growth during further pregnancy (Da Silva et al., 2016). As increased litter size has resulted in a decreased piglet birth weight and increased within litter birth weight variation, we investigated the relationship between OR and litter characteristics at term.

Characteristics of repeat-breeding female pigs on southern EU commercial farms

A repeat-breeding (RB) occurrence increases non-productive days of female pigs
(NPD), and consequently decreases herd productivity. However, characteristics of RB female pigs are not well defined or studied in swine. Also, few studies have compared lifetime reproductive performance between RB and non-RB female pigs.
