“…In group II, 23.3% of samples were cloudy and 6.7% were cloudy with lumps. The physical evaluation showed that cloudy urine and with ammonia odor indicate the occurrence of UTI, as described by Alberton et al (2000), Pôrto et al (2003), and Menin et al (2008). No significant difference was found between groups I and II regarding labor duration, which took on average 347 min (Table 1).…”

“…When assessing physicochemical and microbiological aspects of the urine of culled sows, Pôrto et al (2003) observed prevalence of UTI in 45.7% of urine samples. Through diagnosis using reagent strips, Alberton et al (2000) identified high prevalence (28.3%) for urinary tract diseases.…”

Correlation between urinary tract infection and reproductive performance of sows

et al. 2018

This study aimed to assess the prevalence and influence of urinary tract infection on the reproductive performance of sows. The animals underwent urine tests using reagent strips and diagnosed as positive or negative. They were then divided into two groups of 30 positive and 30 negative sows for urinary tract infection. Each sow was considered an experimental unit and was followed from labor to weaning. The animals were assessed for their reproductive performance (labor duration, number of live births, mummified piglets, and stillbirths, and postpartum diseases). After weaning, the weaning-estrus interval and rate of return to estrus were assessed. A thermographic camera was used to identify hyperthermia of the mammary system and its relation with the onset of urinary tract infections. The prevalence of urinary tract infection in prepartum sows was 41.1%. Urinary tract infection does not impact labor duration, number of live births, mummified piglets, and stillbirths, number of sows culled, weaning-estrus interval, or return to estrus after insemination. However, it was considered a predisposing factor for the occurrence of postpartum vaginal discharge. There is no correlation between the occurrence of urinary tract infection and mammary system temperature in sows.

“…This occurs because the proteins have a high molecular weight and the few that can pass through the glomerular filter are then reabsorbed by the renal tubules. A small amount may, however, escape and appear in urine in trace amounts, especially in concentrated urine 33 . However, the small proteinuria present in healthy animals can be caused by stress, as well as in commercial pig farming where it is a problem in the system, or a high amount of protein ingested 33 .…”

However, the small proteinuria present in healthy animals can be caused by stress, as well as in commercial pig farming where it is a problem in the system, or a high amount of protein ingested 33 . Thus, the protein requirement of the collared peccary is 14%, relatively low crude protein 17 and nutritional requirement of 794.05 kcal/day 34 , however, the diet offered to the animals contained 16% crude protein in the diet of the animals, thus, it may have caused proteinuria in animals both on day 0 and in the other periods of the experiment.…”

Collared Pecary (tayassu tajacu) as a new model of renal ischemic injury induced by clamping the renal artery

et al. 2014

PURPOSE:The use of the collared peccary as an experimental model for ischemic nephropathy. METHODS:A total of 12 collared peccary (Tayassu tajacu) was used and ischemic nephropathy was induced in six of these animals that constituted the experimental group (G1) while the other six formed the control group (G2). Ischemic nephropathy was induced surgically by partial occlusion of the left renal artery. The disease course was assessed by hematological tests, serum chemistry, urinalysis, ultrasound (US) and doppler ultrasound function of the renal artery before induction, and at five, 10, 15 and 20 days after surgery.Twenty days after the occlusion, unilateral nephrectomy and histopathological examination were performed to assess renal morphology. RESULTS:Statistical analysis by Fischer's test showed a significant difference (p<0.05) between the control group and the experimental group. The histopathological examination showed glomerular, tubular and interstitial lesions. In the experimental group, 83.3% (5 /6) showed moderate renal lesions and only 16.7% (1/6) were classified with no lesions. The ultrasound examination of the right kidney presented statistical difference between day 5 and day 10 post occlusion. CONCLUSION:The collared peccary as a good experimental model for ischemic renal disease, because it could be manipulated during the research time without death, with health conditions that permit any subsequent procedure for disease therapy.Key words: Artiodactyla.
