Abstract

Fatty acids are very important biological substances due to their metabolic, structural and signal- ing functions. Omega-3 has different beneficial, harmful and neutral effects on adipokines. Adi- pokines have autocrine, paracrine and endocrine effects on metabolism. In the study 54 German Fawn x Hair crossbred goats were synchronized using intravaginal sponges. During the first pe- riod (mating-75 days), all animals were fed a diet supplemented with protected fat and during the second period of pregnancy (76 days-kidding), one of the groups was fed a diet supplemented with fish oil and other was fed a diet supplemented with protected fat. Serum leptin, ghrelin, adi- ponektin and omentin levels were measured by ELISA system. Distributed fed (roughage and concentrate) were sampled and dry matter, crude protein, fat, and ash were determined by AOAC (1988) analysis methods. The Acid Detergent Fiber (ADF) and Neutral Detergent Fiber (NDF) analysis were conducted using heat stable α-amylase and sodium sulphite. Fat source (fish oil or protected fat) affected feed consumption and the highest feed consumption was found in the group fed with protected oil first half of the pregnancy and with fish oil in the second half of the pregnancy and in the fish oil group during the pregnancy. It was determined that the use of fish oil during pregnancy did not affect ghrelin, leptin and omentin concentrations in serum. Adipokine levels of fish oil fed animals during any period of pregnancy were found to be high and it was also found that serum adiponectin levels in goats fed with diet containing fish oil in the first half of pregnancy and protected fat in the second half were statistically significantly high in adipokines.

Abstract

A i m s: Gestational diabetes mellitus (GDM) is an emerging worldwide problem. Changes in clinical characteristics of women affected by GDM in a long-term perspective are still not properly investigated. We aimed to examine such changes over a decade in a retrospective single-center analysis.
M e t h o d s: The medical documentation from Department of Metabolic Diseases, Krakow, Poland was analyzed. We included 633 women consecutively diagnosed with GDM in one of three time intervals: 2007–2008 (N = 157), 2012–2013 (N = 272), 2016–2017 (N = 234). Statistical analyses were performed.
R e s u l t s: Comparison of the three groups identified differences in the mean age of women at the GDM diagnosis (30.7 ± 5.0 years vs. 31.2 ± 4.7 vs. 32.5 ± 4.7, respectively, starting from the earliest 2007–2008 group), pregnancy week at GDM diagnosis (28.0 ± 5.3 wks. vs. 25.9 ± 4.9 vs. 23.4 ± 6.8), the proportion of women diagnosed before the 24th week of pregnancy (12.8% vs. 16.5% vs. 31.3%), and gestational weight gain (12.4 ± 5.0 kg vs. 10.4 ± 5.2 vs. 10.0 ± 5.7); (p = 0.001 or less for all comparisons). We also found differences for glucose values on fasting and at 2 hours with the highest (0 min) and lowest level (120 min) in the 2016–2017, respectively. Finally, a borderline difference for the weight, but not for BMI, was found (64.1 ± 14.1 kg vs. 66.2 ± 13.1 vs. 67.8 ± 15.6; p = 0.04). Differences were also identified in the post hoc analysis between cohorts.
C o n c l u s i o n: This retrospective analysis illustrates changes in characteristics of women with GDM occurring over the period of decade in Poland. They likely result from both epidemiological trends and modifications of the WHO criteria for the GDM diagnosis.

Abstract

Prolonged exposure to stress may cause adverse effects on animal physiology. It is especially important during the gestation period as female physiology can affect the unborn offspring in the form of prenatal stress. Intensive pig farming industry developed gestation crates that enable to keep sows during gestation period in small stalls which do not allow animals to move freely for a maximum of 4 weeks after successful insemination (Council Directive 2008/120/EC). Although these crates have production advantages, many health and welfare issues have been raised recently. In this study we tested to what extent the lack of movement of sows kept in the gestation crates had an impact on some blood and saliva constituents of new-born piglets. In total, the samples were collected from 80 piglets when they were 3, 7 and 21 days of age and tested for cortisol levels in blood and saliva, acute phase proteins (amyloid A, C-reactive protein, haptoglobin) and lymphocytes proliferation index (in response to ConA, PHA and PWM). 40 piglets were from sows kept in free movement housing (FM group) from day 1 to day 100 of pregnancy and forty piglets were from sows in the movement restriction group (MR), in which the sows were kept in crates just allowing them to stand up and lie down from day 1 to day 100 of the pregnancy (research was conducted before the implementation Directive 2008/120/EC i.e. January 1,2013). The results of the study showed that the piglets delivered by sows kept under movement restriction conditions exhibited higher cortisol and acute phase protein levels as well as a lower lymphocytes proliferation index. This suggests that lack of movement in sows during the gestation period influences piglets’ physiology and indicates that the piglets are suffering from prenatal stress caused by insufficient housing conditions of their mothers potentially leading to poor health and welfare of their offspring.
