With THI >72 during 07 months in the study area, which significantly (P<0.001) decrease the MY (-15.5% corresponding to 21.73 kg). Also, calving periods led to a significant drop (P < 0.001) in overall MY (7030.35 kg) of the order of (-14.6%), and over the lactation length (353.43 d), which explains 41% of the variations in MY. In addition, the non-significant effect (P=0.212) of the lactation range on the increase in MY, moreover, the lactation length shows a non-significant (P = 0.108) decrease (-4.68%) during heat stress (HS). Furthermore, the significant effect (P <0.001) of the interaction (Milking frequency × THI) on MY, when THI variates from < 74 to > 84, with regression of (-16.82% and -08.82%) of the MF (2X and 3X), respectively. Again, the NH cow is less sensitive to hyperthermia, so THI explains only 2% of the variation in MY levels. Thus, NH in arid regions have the ability to acclimatize to Saharan environmental conditions.","PeriodicalId":170796,"journal":{"name":"Archiva Zootechnica","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125728527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental diets added 16.56% sunflower meal and 20% rice bran, increasing the dietary cellulose up to 7%. The fibre digestibility was improved using on E2 (0.015% enzyme); E3 (0.015% phytoadditive) and E4 (0.015% enzyme + 0.015% phytoadditive). The high fibre diets had no negative impact on productive performances and egg quality parameters. Yolk cholesterol significantly decreased (P<0.05) on E1, E3 and E4 groups compared to C, E2 groups. Villi height increased significantly (P<0.05) on E2 group compared to all other groups.

N2O is a greenhouse gas with 298-fold higher global warming potential (GWP) than CO2. Pigs accounted for about 26% of N2O emissions. The formation of N2O occurs through nitrification and denitrification processes in manure. This study aimed to estimate N2O production in the manure of growing-finishing pigs by using our experimental data in the model. The associative effects of dietary mustard and grapeseed oil cakes (MxG), as an alternative for sunflower meal (SFM), on performance and efficiency traits were also determined. Forty growing-finishing pigs were randomly allocated in two groups (2 replicates per group) fed two diets: C diet (based on SFM, 15 wt) and E diet (based on M and G mixture, 7:8 wt:wt). Our model includes as initial input data: body weight (BW), feed intake, nitrogen intake, dietary dry matter, and fibre intake. Using literature prediction equations, including total nitrogen output (TNO) as the main parameter, we established N2O production expressed as equivalent CO2 (E-CO2). A decline with 3% for BW (P=0.44), respectively 9.0% for average daily gain (ADG, P=0.21) in pigs given MxG was recorded. Correlated with growth parameters, efficiency traits (feed intake, feed: gain ratio, N and fibre intake) were decreased as well (P>0.05). Dietary addition of MxG led to a 5% lower level of N2O production in manure. The reduction of TNO was not significant (<7.14% in the E diet compared to the C diet). In our trial, a relatively low N intake percentage is retained in the pigs body (35.56% in the C group and 35.98% in the E group, P>0.05). Based on these results, we conclude that the inclusion of 15% MxG mixture in pigs diets, although slightly declining growth parameters, is a valuable nutritional solution by their contribution to lowering N2O and N output in the manure.","PeriodicalId":170796,"journal":{"name":"Archiva Zootechnica","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122186668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exposure to ZEA affects the health of animals and humans, predominantly by disrupting the activity of the reproductive system due to its structural resemblance to estrogen, but it also affects other systems such as the digestive, nervous and immune systems. The main route through which ZEA enters the body is by ingestion, the intestinal epithelium being the first tissue exposed to the toxin. The intestinal barrier not only has a mechanical role in defending the body, it is also able to secrete effector molecules involved in the immune and inflammatory response such as cytokines. In this in vitro study, performed on the line Caco-2, the effects of ZEA on inflammation of the intestinal epithelium were studied by quantifying gene expression and protein concentration of pro-inflammatory cytokines IL-1β, TNF-α, IL-6 and IL-8. Also, the mechanism of inflammation that ZEA can affect at intestinal level was investigated by monitoring the level of mRNA and the protein expression of the nuclear receptors NF-κB and Nrf-2. The results of this study demonstrate that ZEA has an anti-inflammatory character on human intestinal epithelial cells Caco-2, reducing the gene expression of the pro-inflammatory cytokines IL-1β, TNF-α, IL-6, IL-8. Also, ZEA led to a decrease in the protein concentration of IL-6 and IL-8. The anti-inflammatory response seems to be induced by modulation of gene and protein expresion of NF-κB and Nrf-2 nuclear receptors.","PeriodicalId":170796,"journal":{"name":"Archiva Zootechnica","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126677094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Blood samples were used for analysis of the following plasma parameters: total protein, albumin, globulin, urea, creatinine, cholesterol, AST, ALT, glucose and serum for thyroid hormones. Histology analyses were performed on the carp liver samples. During the experimental period, fasting and refeeding were influenced significant on studied biochemical parameters, except glucose and urea.
