The vitamin D content of forages can vary considerably and depends, among others, on plant species, plant maturity and climate fluctuations. Ultraviolet B (UVB) exposure causes conversion of provitamin D to vitamin D and thus represents the most important influence. To characterise this effect, two batches of a young-cut roughage of high hygienic and nutritional quality were exposed to constant artificial UVB-irradiation up to 192 h and were sampled at regular intervals. In previous studies, both ergocalciferol (vitamin D₂), cholecalciferol (vitamin D₃) and/or their metabolites have been detected in plants. Therefore, the present roughage was analysed for both D₂ and D₃. Whereas cholecalciferol never exceeded the detection limit of 0.25 µg/100 g, ergocalciferol increased from 2.22 µg to 19.15 µg/100 g dry matter in a time-dependent manner. Additionally, the values indicate an interplay with other factors not investigated in this study, for example, leaf-stem-ratio in the different samples. The high amounts of ergocalciferol in the experimental roughage after UVB-exposure confirm the value of hay as a vitamin D source for managed herbivores. The quick rise with time cautions against neglecting UVB-irradiation's effect on feed, both in practical as well as in experimental settings.</p>\u0000 </div>","PeriodicalId":14942,"journal":{"name":"Journal of Animal Physiology and Animal Nutrition","volume":"109 3","pages":"747-752"},"PeriodicalIF":2.2,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142914958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among food leftovers, former food products (FFPs) are no more intended for human but still suitable for animal consumption. However, the metabolic impact of FFP has never been investigated. In this study, we evaluated the impact of replacing 30% of conventional cereals with FFP on abdominal fat quality and plasma metabolome modulation in postweaning piglets. Thirty-six Large White × Landrace postweaning piglets (28 days old) were randomly assigned to three dietary groups for 42 days: control (CTR), 30% replacement of CTR with salty FFP (SA), 30% replacement of CTR with sugary FFP (SU). Body weight and feed intake were measured to calculate average daily gain, average daily feed intake and feed conversion ratio. The fatty acid profile of the diets and the abdominal adipose tissue was determined and a mass spectrometry-based untargeted metabolomics investigation was performed on plasma samples. The growth performance was not significantly affected by SA and SU diets. Despite the different fatty acid profile of the diets, the fatty acid profile of the adipose tissue was rebalanced in piglets. The plasma metabolome was more affected by the time factor rather than the treatment factor. Six metabolites were significantly altered in SA and SU groups compared to CTR: caffeine, theobromine, proline-betaine, dipalmitoyl-phosphatidylcholine (PC 32:0), spermidine and <span>l</span>-tryptophan. Caffeine and glycerophospholipid pathways were significantly different between CTR and SA and SU groups, although no impact on other metabolic pathways was observed.

The replacement of PBM with HPM was evaluated using five formulations with similar chemical compositions: control (PBM as the sole protein source) and the inclusion of 5%, 10%, 20%, and 30% HPM (on an as-fed basis). Thirty cats were distributed into two randomised blocks of 15 cats, with 3 cats per diet in each block, totalling 6 cats per food. After 10 days of diet adaptation, the urine of the cats was quantitatively collected from Days 11 to 15, and on the day 21 blood samples were collected and blood pressure was evaluated. Data were subjected to analysis of variance and the means were compared by polynomial contrasts. Non-parametrically distributed variables were compared using the Kruskal–Wallis test (<i>p</i> &lt; 0.05). All the cats remained healthy throughout the study period.

Eighty fully grown New Zealand White does weighing between 2.75 and 3.00 kg live weight and aged 5–6 months old were utilized. Rabbits were allocated into four groups (20 rabbits/group): control group (basal diet), T1 (5% fenugreek), T2 (15% Berseem seeds), and T3 (2.5% Fenugreek with 7.5% Berseem seeds). We noticed that the dietary inclusion of Fenugreek and/or Berseem seeds significantly improved weight and total weight gain of litters. The increased body weight and decreased feed costs were accompanied by improved return parameters, including total return, net return economic efficiency, and relative economic efficiency, particularly in the T2 and T3 groups. Moreover, milk yield was increased in treated groups compared with those fed basal diet. The improved milk yield was associated with the enhancement of mRNA expression of the prolactin gene and improved mammary morphological characteristics, especially in the T1 group. Indeed, a rabbit does in T2 group revealed an earlier nest building, a higher nest quality, and an increased willingness to nurse. While those in T1 group presented the highest percentages of kits with full bellies. Interestingly, T2 and T3 had large mature follicles (preovulatory follicles) and few numbers of small follicles which was associated with a marked upregulation of mRNA levels of follicular stimulating hormone gene.

Twenty-four 40-week-old, healthy New Zealand white male rabbits were divided into four groups. The first group consumed tap water and served as a control.

The ejaculate volume, sperm concentration, vitality, motility and velocity of the H₂O₂ group were considerably lower than those of the other groups. Frozen/thawed spermatozoa showed more dramatic decreases in motility and velocity as a result of H₂O₂ consumption. The plasma concentrations of testosterone and total antioxidant capacity were also lowest in the H₂O₂-treated rabbits, while malondialdehyde levels were highest. Exposure to H₂O₂ increased collagen deposition between ST and epididymal ducts which induced testicular and epididymis fibrosis. In addition, the spermatogenic and epididymal epithelial cells exhibited signs of apoptosis, degeneration, vacuolation and a reduction in height. Maca intake attenuated most of the damaging effects of H₂O₂ ingestion-induced oxidative stress. Furthermore, H₂O₂-treated rabbits had modest nuclear androgen receptor positivity, unlike those in the Maca group. The number of Leydig cells significantly increased with daily Maca intake.

The eggs were sorted into four groups: negative control (no injection), positive control (0.9% physiological saline injection), GOS 3.5 mg/egg and LP 1 × 10⁶ CFU/egg. The groups used during the incubation period were the same for the animal trial; each pen/group had 25 chickens.

All data were analysed by one-way ANOVA or repeated measured ANOVA except for the parameters that did not meet the assumption of normality, the Kruskal–Wallis test (Dunn's test) was used. Key findings revealed that hatchability remained unaffected across groups, indicating the safety of the in ovo injections.

The in ovo administration of LP increased the body weight of the chickens during the first-week post-hatch (7 days of age) without impacting feed intake and feed conversion ratio in the later stages.
