Rabbits (n = 160) were randomly divided into four groups. The control group (C) received non-supplemented pellets, while in the other groups the pellet contained 1% algae (A), 3% sunflower oil (OS), or 3% soybean (SO) oil. Soybean and sunflower oil (3%) in the diet increased the linoleic acid (LA) content in meat of 12-week-old rabbits. The use of algae (1%) in the diet increased the n-3 PUFAs eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) compared with the vegetable oil and control groups, and decreased the n-6/n-3 ratio. The effect of the diet on FTO and FABP4 gene expression depended on the age of the rabbits. In older animals (18 weeks of age) the expression of these genes was highest in the group with 1% algae. Furthermore, the FA profile and FTO and FABP4 gene expression were affected by the age of rabbits, but not by sex. The results showed that diet is an important tool to modulate the FA profile in rabbit meat by changing the expression of fat metabolism–related genes.","PeriodicalId":50791,"journal":{"name":"Animal Science Papers and Reports","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135736190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate performance, nutrient digestibility, egg quality, egg quality according to their storage period, and the fatty acid profile of Japanese quail egg yolk ( Coturnix coturnix japônica ). The design was completely randomized, in which 270 female quails were allocated in a 3x2 factorial diet arrangement: three lipid sources (soybean oil, poultry fat, and beef tallow), supplemented or not with an emulsifier, following two nutritional strategies – a diet formulated to meet the nutritional requirements proposed by INRA and a diet formulated with a reduction of 96 Kcal/kg of feed and added emulsifier. The effects of interactions between the lipid sources and the emulsifier were studied, their isolated effects when interactions were absent and the effect of storage time, and their interactions with the factors evaluated for egg quality variables. Feed intake was greater when beef tallow was added to the diets, while feed conversion was worse for birds fed diets with soybean oil and the emulsifier. Quails fed the diet with the emulsifier and soybean oil produced better quality eggs represented by the higher Haugh unit. Diets with beef tallow and poultry fat provided a higher percentage of palmitic and unsaturated fatty acids in the quail egg yolk. Alternative lipid sources such as beef tallow and poultry fat can be used as a substitute for soybean oil with added emulsifiers in diets for egg-laying quails without impairing performance and egg quality. The use of emulsifiers with alternative lipid sources to soybean oil can be considered a nutritional strategy in laying quail diets, but the reduction of energy in the diet must be adequate for the species.","PeriodicalId":50791,"journal":{"name":"Animal Science Papers and Reports","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135737816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been previously shown that, when forming embryoid bodies with wild-type ESCs, ESCs lacking a functional copy of the gene encoding the adhesive protein E-cadherin (Ecad −/− ) preferably sort out to the outside compartment, thus forming the primitive endoderm (PrE) lineage. However, little or no information is available regarding the dynamics of Ecad −/− cells in the actual blastocyst, and so the aim of this work was to determine in which of the three blastocyst cell lines - trophoblast (TE), epiblast (Epi), or PrE - Ecad −/− cells would be located in the embryo environment. For this purpose we injected ESCs into embryos at various stages of pre-implantation development. We used a H2B-GFP cell line expressing histone H2B conjugated with green fluorescent protein (H2BEGFP), as well as a Ecad −/− cell line, in which cells exhibit weaker adhesive properties than wild-type Esc because of their allelic deficiency in the locus encoding cadherin CDH1. We have demonstrated that these cells exhibit a trend to locate in the TE and much less frequently in the Epi, but never in the PrE. We propose that this may be due to differences in the expression of genes characteristic of these cell lines within the Ecad −/− cell colony.","PeriodicalId":50791,"journal":{"name":"Animal Science Papers and Reports","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135736189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study included 5,122 PLW gilts from 160 breeding herds in Poland, which reproductive performance was analysed on the basis of the rearing results of 20,662 litters. The gilts were divided into two groups differing in mean standardised backfat thickness (P2+P4/2) on the performance test day: I≤10 mm, II&gt;10 mm. Sows in group I vs II had a three month shorter herd life (P≤0.001), gave birth to fewer litters and piglets (P≤0.001), but the average number of piglets born alive and reared to 21 days of age/litter was higher in them (P≤0.001). The number of live-born piglets per 100 days of reproductive life in group I was greater than in group II (P≤0.001). When culling sows in cycles 1–8 and later, there was more intensive culling in group I vs II from cycle 1 to 6 and a lower percentage of sows remaining in the herd. In group I vs II, the proportion of sows with a lifetime productivity of fewer than 30 piglets was 5.5 percentage points higher and that with a production of more than 100 piglets was 1.9 percentage points lower. Our results indicate that the level of fat reserves determined in vivo in breeding gilts can be a preliminary information about the reproductive potential of sows and their predisposition to longevity.","PeriodicalId":50791,"journal":{"name":"Animal Science Papers and Reports","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135737817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pearson correlations were also estimated between biochemical parameters. The study included 26 goats which were divided into SRLV-infected and SRLV-free groups. Blood samples were taken at four points of lactation (days 14, 45, 85, and 240, reflecting perinatal period, early lactation, the peak of lactation, the end of lactation). Hepatic, kidney, bone, cardiac, pancreatic, lipid profiles and CRP concentrations were analyzed. Choline esterase (CHE), calcium (Ca*), creatine kinase (CK), and triglyceride (TRI) levels differed between groups, on day 240 (p≤0.05). Some parameters varied during lactation, with similar patterns observed in both groups. Mainly positive correlations between biochemical parameters were observed in the SRLV-free and SRLV-infected groups both within organ profiles and between them. CRP was not correlated with any biochemical parameters in the SRLV-free group but was negatively correlated with parameters of the liver, kidney, cardiac, and lipid profiles in the SRLV-infected group. The correlations suggest that SRLV may affect the kidneys, liver and heart, even in asymptomatic animals. Some differences were found between asymptomatic SRLV-infected and SRLV-free goats in the last stage of lactation; however, the nature of these changes requires further detailed studies.","PeriodicalId":50791,"journal":{"name":"Animal Science Papers and Reports","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135735994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A group without a nitrite source (NC) and a group cured with 100 ppm of sodium nitrite (PC) were used as negative control and positive control groups, respectively. The nitrite content of the plasma-activated solutions was adjusted to match that of the positive control by calculating the required plasma treatment time, based on previous studies. The obtained results showed that addition of treated solutions with nonthermal plasma for a 70 min, at a level of 20% in relation to the meat, can have beneficial effects on nitrosylhemochrome content, redness, and TBARS values of restructured jerky. These effects were statistically comparable (p≥0.05) to sodium nitrite-cured samples. Furthermore, compared to the PC group, the T1, T2, and T3 treatments exhibited significantly lower water activity and higher protein content (p<0.05). The T2 and T3 treatments also showed increased lightness and shear force values (p<0.05) compared to the control groups (NC and PC). It should be noted that the T3 group had the highest (p<0.05) residual nitrite content among all the samples. However, a sensory analysis is necessary to assess consumer acceptance with regard to differences in the odor profile of the treatments, according to the Principal Components Analysis (PCA).","PeriodicalId":50791,"journal":{"name":"Animal Science Papers and Reports","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135736188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the rapid implementation of genomic selection (GS) in the poultry industry and a decrease in the cost of genotyping, genomic prediction (GP) is a feasible way to increase productivity. Moreover, a pre-selection of SNPs could represent a reasonable option to speed up GP. We used 312 F2 broiler chicken genotyped with 60K Illumina Beadchip to investigate the effect of reduced SNP densities on accuracy and bias of prediction using single-step genomic BLUP (ssGBLUP) for BW at 2-4 weeks of age (488 chickens). To investigate the effect of reduced SNP densities by varying minor allele frequency (MAF), SNPs were grouped into five subgroups with MAF of 0.05-0.1, 0.1-0.2, 0.2-0.3, 0.3-0.4 and 0.4-0.5. The accuracy and bias of genomic predictions from different MAF bins were compared to that using a standard array of 60k SNP genotypes and the traditional BLUP method.
