Machine learning can predict weaning to estrus interval based in lactation intake of sows

New technologies and innovative farm’s equipment allow massive data collection that properly used can help to optimise production. In particular, electronic sow feeding is helping to understand better sows’ needs and performance. This study aimed to...

Effect of IGF-1 level at weaning on subsequent luteal development and progesterone production in primiparous sows

Insulin-like growth factor-1 (IGF-1) is known to be related to follicle and oocyte development in sows. We hypothesized that a higher IGF-1 level at weaning may derive better luteal development during early pregnancy in primiparous sows.

Differences in return to estrus rate and number of total born piglets caused by variations in peoples’ artificial insemination technique

Artificial insemination technology is widely used in pig breeding herds. Few information is available about the impact of the variation in peoples’ artificial insemination technique on the reproductive performance in sows.

The effect of altrenogest treatment on incidence and prevention of early parturition in sows

Altrenogest is proven the effective tool for synchronization of gilts. Physiological length of gestation is considered 115-116 days, with high variability reported (110-121d of pregnancy), farrowing before day 113 considered as early parturition. The aim...

VULVAR DISCHARGE SYNDROME IN SOWS AFTER ARTIFICIAL INSEMINATION 

Introduction: Vulvar discharge is frequently observed in sows with bacterial infection of the urogenital tract and cause economic losses due to reproductive failure in affected sows. Several risk factors for this condition have been described and,...

SEVERE UDDER EDEMA AS A CAUSE OF REDUCED COLOSTRUM QUALITY AND MILK PRODUCTION IN SOWS – A CASE REPORT

A piglet-producing herd in Finland suffered from inadequate milk production of sows. Investigation of the problem revealed that 35% of the sows had low water intake, constipation and excessive swelling of the udder prior and during parturition. The...

BACTERIURIA IN SOWS IS ASSOCIATED WITH AN INCREASED RISK OF STILLBIRTHS  

Introduction: Previous research showed that urinary tract infections (UTI) in sows are associated with poor reproductive performance. Parameters such as farrow rate, risk of rebreed, and weaned piglets per litter has been associated with the presence of...

A COMPARISON OF DIFFERENT FARROWING SYSTEMS WITH REGARD TO THE COLOSTRUM SUPPLY OF PIGLETS

Introduction: Especially after birth, the colostrum supply of newborn piglets is of particular importance for the survival and further development of the piglets. The aim of this study was to investigate in what way the farrowing system and thus the...

IMPACT OF RUNTING ON COLOSTRUM INTAKE, SURVIVAL CHANCES AND DEVELOPMENT

Runt pigs are intrauterine growth retarded animals characterized by low birth weights (BW). They have higher mortality rates, reduced daily gain and pork quality and increased feed conversion rate. Colostrum intake (CI) is negatively correlated with BW and litter size. For current breeds, a minimum BW of 1.13 kg is needed for normal survival chances. The objective of this study was to investigate the relation between low BW, CI, mortality and development.

IMPACT OF OESTRUS SUPPRESSION IN CARCASS QUALITY OF GILTS INTENDED FOR TERUEL DRY-CURED HAM PRODUCTION

Increasing fatness and avoiding puberty are desirable in gilts intended for Teruel dry-cured ham. This study was conducted to assess the impact of Vacsincel® (Zoetis), vaccine indicated for temporary oestrus suppression, on gilt genital organs and carcass fat, relative to time of second dose before slaughter.

INFLUENCE OF TRANSPORT TEMPERATURE IN SEMINAL DOSES: BTS VS LONG TERM EXTENDERS

The transport temperature of boar semen doses is a critical factor to maintain an optimum seminal quality until the artificial insemination time. The spermatozoa metabolism decreases at 16ºC, which favors the preservation of viability for a longer period. Extenders should protect and buffer the harmful effects (capacitation, decrease mitochondrial activity, apoptotic process,...) of temperature changes during transport and storage in sperm cells of seminal doses for an optimal fertilizing capacity. The objective of this study is to evaluate the protective effect of the extenders BTS vs. Long-term against the influence of the transport temperature of seminal doses.

POST MORTEM ANATOMICAL STUDY OF BOARS TESTICLES ELIMINATED FROM ARTIFIFICIAL INSEMINATED CENTERS

Post-mortem collection of boar genitalia in the slaughterhouse and its later study in the laboratory is a useful diagnosis tool for the veterinarian. In the past several years, an increase of slaughtered young boars due to bad semen quality has been recorded. This fact worsens the animal amortization and decreases the productive capacity of the boar stud because they are slaughtered long before the end of their useful life. The aim of this study was to analyze the relationship between anatomicalhistological study (through in vivo biopsies) and reproductive problem or semen quality able to make an early diagnosis of treatable diseases, thus increasing the boar retention rate.
