The objective of this study was to determine the tissue composition of the carcass of growing New Zealand White rabbits based on the shoulder and neck traits (weight, meat and bone weights). Live weight and characteristics of dissected meat and bone tissues (neck, breast, rib, loin, shoulder, and leg) of 80 rabbits were recorded. Total carcass tissue weights (carcass fat weight, carcass meat weight – CMW, and carcass bone weight – CBW) were calculated and correlation and regression analyses were implemented. Shoulder, neck, shoulder meat, bone and neck meat were correlated (P < 0.0001 and < 0.001) with CMW and CBW. In conclusion, cut weights and tissue content of the shoulder and neck provided good predictions for total meat and bone weights of growing New Zealand White rabbits.","PeriodicalId":14919,"journal":{"name":"Journal of Animal and Feed Sciences","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44333974","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}

Dietary treatments were: CON – basal diet, TRT1 – CON + 0.10% DHA, TRT2 – CON + 0.25% DHA, TRT3 – CON + 0.50% DHA. DHA supplementation resulted in a linear increase ( P = 0.046) in final body weight of finishing pigs. DHA supplementation increased average daily gain (ADG) in the TRT3 group compared to the CON group at week 6. In addition, the gain to feed ratio (G:F) was increased in the TRT3 group compared to the CON group. Increasing dietary DHA levels linearly improved ADG ( P = 0.046) and G:F ( P = 0.021). DHA supplementation did not influence nutrient digestibility. The pH, water holding capacity, cooking loss, and meat colour were not affected by the supplementation with graded DHA levels. On day 7, drip loss was reduced in the TRT2 and TRT3 groups compared to CON. However, faecal microbial and faecal score measurements remained unaffected among the treatments.

The purpose of this study was to explore whether the addition of feeding superoxide dismutase (SOD) to yellow feather broilers in the early stages of growth could affect their growth performance, antioxidant properties, digestive enzyme activity and blood biochemical indices. A total of 320 male one-day-old yellow-feather broilers were evenly divided into 5 groups of 8 replicates each, with 8 chickens in each replicate. The control group was fed the basal diet, and four experimental groups were fed the basal diet + 100 mg/kg, 200 mg/kg, 400 mg/kg, and 800 mg/kg SOD, respectively. SOD was provided in powder form and the enzyme activity was 20 000 IU/g. Pre-feeding the basal diet for three days was followed by feeding the experimental diet for the trial period of 28 days. The results indicated that SOD significantly increased final body weight and average daily gain ( P < 0.05) and significantly decreased the feed:gain ratio ( P < 0.05) of broilers without affecting average daily feed intake ( P > 0.05). Dietary SOD increased total antioxidant capacity and glutathione peroxidase activity (GSH-Px) ( P < 0.05), reduced serum malondialdehyde ( P < 0.05) levels, and increased total SOD, catalase and GSH-Px ( P < 0.05) activities in the liver. The results demonstrated that dietary SOD supplementation improved the antioxidant capacity of broilers. However, SOD did not affect the activity of digestive enzymes (α-amylase, trypsin, lipase) in the duodenum, jejunum and ileum ( P > 0.05). In addition, SOD reduced serum alanine transaminase and aspartate transaminase ( P < 0.05) activity, indicating reduced burden on the liver. Based on these results, it can be concluded that the addition of different SOD concentrations to the diet can enhance the growth performance and antioxidant capacity of broilers. The addition of SOD provided the optimum effect in the range of 400–800 mg/kg.","PeriodicalId":14919,"journal":{"name":"Journal of Animal and Feed Sciences","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44082909","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 aim of this study was to evaluate the replacement of oat hay exclusively with fermented prickly pear in developed multi-nutritional blocks (MNBs) on steer production efficiency and in vitro rumen fermentation parameters. Two experiments were performed: Trial 1 ( in vitro assay) evaluated in vitro fermentation parameters of three MNBs replacing oat hay (MNB0 – 0% prickly pear, MNB1 – 25% prickly pear, MNB2 – 25% fermented prickly pear). Trial 2 ( in vivo assay) evaluated the effect of MNBs on steer production performance. Both experiments were established as a completely randomized design. The values for proteins, metabolisable energy, gas production, methane and CO 2 were higher in MNB2 ( P < 0.05) group. Total and individual volatile fatty acids differed between experimental MNBs groups ( P < 0.05). Mean body weight and mean live-weight gain of steers were increased with MNB supplementation in T2 group by 12 and 37%, respectively. Dry matter digestibility was higher ( P < 0.05), but methane and CO 2 production in the rumen decreased with MNB supplementation ( P < 0.05).

Zaworska-Zakrzewska","doi":"10.22358/jafs/149656/2022","DOIUrl":"https://doi.org/10.22358/jafs/149656/2022","url":null,"abstract":"In recent years, there has been a growing interest in the use of legume seeds for human and animal nutrition for various reasons. Independence from the import of genetically modified soybean products, feed quality and price play an important role in animal nutrition (Święcicki et al., 2020). Legume seeds are a rich source of nutrients for humans, thus their consumption prevents various diseases of civilization, such as hypertension, type 2 diabetes, hyperlipidaemia, and overweight (Conti et al., 2021). Legumes can fix atmospheric nitrogen, improve soil physical condition, require lower energy input (Rubiales and Mikic, 2015) and perfectly complement crop rotation. It is well known that legumes also contain antinutrients (Gulewicz et al., 2014), such as trypsin inhibitors, lectins, phytic acid, tannins, quinolizidine alkaloids, saponins, and raffinose family oligosaccharides (RFOs). They have a diverse structure, and their activity and concentration in seeds are species-specific. Chemically, these compounds are sucrose homologues with (1→6) glycosidic linkages of galactose molecules. RFOs perform critical physiological functions. They increase drought and low temperature resistance, are responsible for respiration during germination, and extend the shelf life of legumes (Gu et al., 2018). Although RFOs are considered antinutrients for animals (Banti, 2021), recently these compounds have been recognized as functional substances with ABSTRACT. The interest of consumers, as well as the food and feed industry in legumes is constantly increasing. However, the use of legume seeds is limited by the fact that they contain various non-nutritive compounds such as raffinose family oligosaccharides (RFOs). On the other hand, RFO compounds are considered prebiotic substances improving health and growth of organisms. Our study consisted in the long-term monitoring of RFO contents in seeds of several legumes cultivated in Poland. The seeds of pea (25 cultivars), faba bean (5 cultivars), and lupins (41 cultivars) were harvested between 2013 and 2019, whereas soybean seeds (27 cultivars) were harvested between 2015 and 2019. The analysis showed that the content of RFOs in soybean seeds ranged from 33.75 to 69.30 mg per g dry matter (DM), 57.23 to 130.38 mg/g DM in lupin seeds – 52.03 to 80.60 mg/g DM in pea seeds, and from 32.15 to 65.17 mg/g DM in faba bean seeds. Yellow lupin seeds had the highest total RFO contents in DM, whereas faba bean and soybean seeds showed the lowest RFO contents. Stachyose was the dominant oligosaccharide in all soybean and lupin seeds, while verbascose was the dominant oligosaccharide in most pea and faba bean seeds. Some pea cultivars contained more stachyose than verbascose. Crop species, cultivar, growing environment, and processing methods determine the suitability of individual seeds for the feed and food industry.

Consequently, it is necessary to find new sources of antimicrobial compounds, which has opened up many opportunities for animal nutrition research. The processing of plants (oilseeds, cereals, medicinal plants, etc.) for feed or food, or non-food products (e.g. oil, alcohol, kerosene, etc.) generates a wide range of by-products with significant ABSTRACT. The aim of the study was to investigate the potential of a diet containing rapeseed meal fermented by Saccharomyces cerevisiae as a new sustainable feed to reduce transient intestinal inflammation, diarrhoea and oxidative stress in piglets after weaning. In this study, 16 male post-weaning piglets, with an initial weight of 9.04 ± 0.19 kg, were randomly allocated to two dietary treatments: control and 10% fermented rapeseed meal (FRSM) – 8 pigs/treatment. The experiment lasted 21 days. At the end of the trial, the animals were slaughtered and samples of blood and segments of the jejunum, ileum and colon were collected for determination of plasma biochemical, inflammatory and oxidative stress parameters. Pig performance and diarrhoea incidence were also investigated. The results showed that the FRSM diet had no significant effect on piglet performance, weight and average daily weight gain, as well as plasma biochemical parameters. However, the number of piglets with diarrhoea was higher in the control group than in the group receiving the FRSM diet throughout the experimental period. Moreover, a decrease in TNF-α (P = 0.03) and IL-1ß (P < 0.05) cytokine levels was recorded in the colon and jejunum samples from the FRSM group. In addition, IL-8 and IL-6 concentrations were decreased (P = 0.0009 and P = 0.03, respectively) in the ileum of piglets fed FRSM, indicating the modulatory capacity of this feed in reducing weaning-associated intestinal inflammation. The FRSM diet also improved the antioxidant status and significantly reduced lipid peroxidation and thiobarbituric acid reactive substance levels in plasma (P = 0.022) and in the jejunum (P = 0.028) and colon (P = 0.003), suggesting the potential of fermented rapeseed meal to limit oxidative reactions. In conclusion, the present study showed that fermentation of rapeseed meal using S. cerevisiae enriched the nutrient composition and reduced the concentration of anti-nutrients (e.g. glucosinolates). Moreover, the addition of FRSM to diets of pigs after weaning improved their intestinal health status, indicating its beneficial effect.
