Abstract Soybean meal (SBM) is fed to various livestock species worldwide. It is also present in dog food as a plant protein source, combined with animal-derived ingredients. The aim of this study was to compare the effect of dietary supplementation with fishmeal (FM, an animal protein source) and high amounts of SBM (a plant protein source) on nutrient digestibility, gastrointestinal function and enzyme activity in mink, a model carnivore. The experiment was performed on 14 female American mink of a standard strain. Diet FM was supplemented with 12% FM and 8% ground wheat grain with sugar beet pulp, and diet SBM contained 20% SBM. It was found that the dietary addition of 20% SBM to mink diets negatively affected the digestibility of protein, carbohydrates and energy. Enhanced colonic fermentation processes as a source of additional energy, observed in SBM group mink, were not sufficient to compensate for the loss of nutrients and energy in the upper gastrointestinal tract (GIT). Therefore, SBM should be applied with caution in diets for carnivorous species.

Abstract The aim of this study was to assess the changes occurring as a result of boiling (100°C, 1 h) small brown snail (Cornu aspersum aspersum) meat in relation to its proximate composition, calcium, phosphorus and cholesterol content, as well as the profile of fatty acids and nutritional quality indices of the lipids. This species of snail was selected for research because it is currently of the greatest economic importance among edible terrestrial snails. It was hypothesized that the cooking effect may be different for foot and visceral sac. Samples for the research were collected from 6 populations bred on experimental fields of the National Research Institute of Animal Production in Balice (Poland). The foot and the visceral sac, the edible parts of the snail species under investigation, were analysed separately, raw and boiled in water. The results were then compared to analogous studies carried out by other authors on beef, pork and poultry. It was found that in the visceral sac of Cornu aspersum aspersum the shares of dry matter, crude protein, fat, ash, calcium and phosphorus were greater than those in the foot (P<0.05), both in the raw and boiled material, whereas the cholesterol content was higher in the foot (P<0.05). Generally, especially in the foot, the heat treatment elevated the levels of the afore-mentioned quantities, yet the increases were not always statistically significant. Boiling the snail meat caused moderate changes in the fatty acid composition. The profile of the fatty acids and the nutritional quality indices of the foot fat were more advantageous than those in the visceral sac. In both parts of the snail carcass, the polyunsaturated fatty acids / saturated fatty acids (PUFA/SFA) ratio substantially exceeded the minimum value of 0.45 recommended by the British Department of Health. However, the n-6/n-3 ratio was too high, exceeding the maximum recommended level of 4.0 twofold and as much as threefold in the case of the foot and the visceral sac, respectively. In the foot, due to boiling, an increase of the share of SFA and monounsaturated fatty acids (MUFA) was observed, while PUFA, n-6 and n-3 decreased. In the visceral sac, the changes were less pronounced with a slight decrease of the share of SFA and PUFA, and an increase of MUFA. Therefore, in the foot, boiling worsened the PUFA/SFA ratio, the nutritive value index (NVI = (C18:0 + C18:1) / C16:0) and dietary fatty acids having a desirable neutral and hypocholesterolemic effect in humans (DFA = Σ MUFA + Σ PUFA + C18:0), but in the visceral sac these indices practically did not change. On the whole, the trends of the changes in terms of chemical composition due to boiling found in the small brown snail meat are similar to those after heat treatment of meat from popular farm animals, but the ranges of the changes differ.

Abstract Worldwide, microbial infections have a serious impact because they cause infectious diseases, death, and significant economic losses. Zoonosis is now a major public health issue on a global scale because of the fast expansion of human exploitation of nature and animal husbandry. Notably, in the past 30 years, over 30 novel human infections have been discovered, 75% of which fall under the category of zoonosis. Resistant strains have emerged as a result of improper use of antibiotics and insufficient infection management posing a serious risk to both public health and the global economy. As alternatives, antimicrobial peptides are showing good results. The majority of living things use antibacterial peptides (ABPs) as a key part of their natural defenses against invading infections. These peptides are cationic, amphipathic, and relatively tiny with varied sequences, structures, and lengths. For the delivery of these efficacious biological peptides, nanoparticles are providing opportunities for effective, safe, and viable delivery. An innovative method of treating infectious diseases is demonstrated by nanoparticles and antibacterial peptides. When ABPs are combined with carrier nanoparticles to optimize distribution, their half-life may be increased, allowing for lower dosages and ultimately lower toxicity. For biological applications, ABPs and nanoparticle conjugates have become effective methods, enabling the treatment, prevention of disease, and detection. More than 50 peptide medications have been made available for purchase on the market as of 2018. Around 25 billion USD is spent on peptide medications each year, including ABPs. But still, there is a gap in the distribution of these ABPs as an alternative to synthetic antibiotics. It might be due to the high cost of these goods. Thus, scientists, researchers, and commercializing companies should work together so that these ABPs with a safe delivery system should be available in the market to combat resistant strains of bacteria. In doing so, we draw attention to the significant advancements made in the field as well as the difficulties still encountered in developing imaging species, active therapies, and nano-drug delivery systems that are functionalized with peptides and proteins for clinical use.

Abstract The aim of this study was to evaluate the heat stress influence on milk production from primiparous and multiparous Holstein-Friesian cows and to estimate economic losses associated with the decrease in the farm’s milk yield. The cows selected for the study were in the middle phase of the 1st, 2nd, and 3rd lactation and were characterized by similar daily milk production. Additionally, the animals were kept in the same conditions and fed with the same feeds throughout the season. The analysis covered two 30-day periods – “cold” (April), in which no days with THI >70 were noted, and “hot” (July), in which THI was above 70 for 90% of the days (74.4 on average). The average daily drop in milk production noted in the hot period was 1.25 kg/cow for multiparous cows and 2.78 kg/cow for primiparous cows. The average daily financial loss resulting from a drop in milk production was €0.55/day/cow in primiparous and €0.46/day/cow in multiparous animals. The calculated daily loss in the profit on production of 1 kg of milk was €0.27/day/kg for primiparous and €0.24/day/kg for multiparous animals. Based on test results, economic losses were simulated depending on the daily milk yield and the size of the primary cattle herd. For the multiparous cows, the estimated losses ranged from €6.07/day (farm sizes 25 cows and average daily milk yield 25 kg) to nearly €219/day (900 cows/25 kg). In larger facilities (900 cows) with an average daily milk yield of 55 kg, the daily loss will be about €481. The obtained results confirmed the assumptions made that with a change in microclimate conditions in the barn, a decrease in the daily production and changes in the milk chemical composition were noted, and the economic efficiency of the studied activity decreased.

Abstract In-vitro meat production has entered into the phase of pilot-commercial scale production from the conceptual-laboratory phase. The main challenge for in-vitro meat production on a commercial scale is the very high cost of its production, mainly due to the cost of cell culture media, growth regulators, and the requirement of highly skilled manpower. The development of serum-free and animal-free culture media with plant, microbial, and fungi-derived compounds through recombinant technology and media recycling is crucial for scaling up in-vitro meat production and reducing the price of the end products. The proper design of bioreactors specific to in-vitro meat production, their automation, utilization of natural and edible scaffolds, and microcarriers made up of edible materials are the present focus of researchers. The co-culturing by proliferating various cells such as adipocytes, chondrocytes, fibroblasts, and endothelial cells are applied for imparting textural and organoleptic attributes to developed products similar to conventional meat. The industrial process to produce in-vitro meat needs a clear synergy between the biological, chemical, technical, and industrial fields because at the moment the main research focus is on the development and improvement of cell lines available to set up cell culture and culture media, bioreactors, cell lines, scaffolding, and biofabrication. The research on in vitro meat is limited by the fact that from the industry the protocols are not properly divulgated.

Abstract The aim of our study was to evaluate the technological (pH, water holding capacity, cooking loss, oxidation-reduction potential, water activity, color parameters, and microbiological purity) and nutritional suitability of the meat of selected lamb breeds by analyzing the indicators (fatty acid profile, fat nutritional indices, lipid oxidation, basic meat composition) that determine the quality of lipids present in the meat. A comparative analysis of meat from native Polish breeds Uhruska, Świniarka, and Wrzosówka showed that these breeds are characterized by high-quality meat. The chemical composition of meat did not significantly differ between the studied breeds. However, the fatty acid composition and atherogenicity and thrombogenicity indices of meat differed significantly between the breeds with the meat of Wrzosówka lambs having a distinct advantage and the most significant potential to protect against cardiovascular problems. Furthermore, the meat of Wrzosówka breed had color parameters that are most desired by consumers. The results presented here are of practical importance as combining meat from different breeds of lambs can allow achieving high product quality. The meat of Wrzosówka breed can be successfully used for producing such products and can serve as flagship meat for export to other European and global markets.

Abstract This study aimed to evaluate the effects of Mentha piperita methanolic extract (MPE) on Cyprinus carpio intestinal microbiota, including total microorganisms gram-negative bacteria, lactic acid bacteria, and fungi count. Liver and intestinal histopathology, and the activity of liver enzymes, were also used to evaluate the possible side effects of MPE. A total of 96 healthy C. carpio fries (76.76±20.26 g) were allocated to four treatment groups with three replications in a completely randomized design. The fries were fed with diets containing 0, 0.5, 1, and 2% extract for 56 days at the rate of 2% of body weight during the experiment. Results showed a significant decrease in total microorganisms, enteric gram-negative bacteria, and total fungi counts (P<0.05). The total lactic acid bacteria count in 0.5% treatment was significantly lower than in control and 2% treated fish (P<0.05). MPE did not affect AST, leading to a significant increase in ALT levels. Simultaneously, ALP represented significantly higher activity in the control group (P>0.05). Microscopic findings revealed marked lesions, including congestion and cell degeneration in the livers of the three groups of fish fed with the extract. The intestinal folds were shortened and blunted in the treatment groups. Furthermore, the intestinal mucosa was necrotic, and the lamina propria was significantly thickened with mononuclear inflammatory cells (P<0.05). Although MPE significantly affects intestinal microbiota, its consumption at 2% is not recommended for C. carpio due to the lesions made in the liver and intestine.

Liver and intestinal histopathology, and the activity of liver enzymes, were also used to evaluate the possible side effects of MPE. A total of 96 healthy C. carpio fries (76.76±20.26 g) were allocated to four treatment groups with three replications in a completely randomized design. The fries were fed with diets containing 0, 0.5, 1, and 2% extract for 56 days at the rate of 2% of body weight during the experiment. Results showed a significant decrease in total microorganisms, enteric gram-negative bacteria, and total fungi counts (P<0.05). The total lactic acid bacteria count in 0.5% treatment was significantly lower than in control and 2% treated fish (P<0.05). MPE did not affect AST, leading to a significant increase in ALT levels. Simultaneously, ALP represented significantly higher activity in the control group (P>0.05). Microscopic findings revealed marked lesions, including congestion and cell degeneration in the livers of the three groups of fish fed with the extract. The intestinal folds were shortened and blunted in the treatment groups. Furthermore, the intestinal mucosa was necrotic, and the lamina propria was significantly thickened with mononuclear inflammatory cells (P<0.05). Although MPE significantly affects intestinal microbiota, its consumption at 2% is not recommended for C. carpio due to the lesions made in the liver and intestine.","PeriodicalId":8235,"journal":{"name":"Annals of Animal Science","volume":"0 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69170548","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}

Abstract This study evaluated the effects of inclusion of raw, hydrobarothermally treated and fermented rapeseed cake (RRC, HRC and FRC, respectively) in diets fed to laying hens. Hydrobarothermal treatment decreased the hydroxyglucobrassicin and neoglucobrassicin content of rapeseed cake (RC), whereas fermentation significantly reduced the content of all glucosinolates (GLS) and phytate phosphorus (PP) concentration. Both HRC and FRC increased the serum concentrations of total protein (TP) and globulin (GLB), compared with group C. Group HRC hens had desirably lowest blood triacylglycerol (TAG) levels and aspartate aminotransferase (AST) activity. Group FRC hens were characterized by the lowest alkaline phosphatase (ALP) activity, and the highest concentrations of phosphorus (P) and triiodothyronine (T3). Regardless of its form, RC improved ether extract (EE) digestibility, and decreased dry matter (DM) digestibility and calcium (Ca) retention. In comparison with group C, RRC, HRC and FRC decreased cecal digesta weight and enhanced the activity of bacterial α-galactosidase and ß-galactosidase; HRC also increased ammonia concentration in the ceca and reduced β-xylosidase activity. The activity of α-glucosidase and α-arabinopiranosidase was highest, and the activity of bacterial β-glucuronidase was lowest in the ceca of group FRC hens. The cecal concentrations of acetic acid, propionic acid, and total short-chain fatty acids (SCFA s) were highest in birds fed a diet containing RRC and lowest in group HRC. In conclusion, RC fermentation considerably reduces the concentrations of GLS and PP. A diet containing 20% FRC is more recommended than diets containing RRC and HRC because it exerted a beneficial effect on metabolic parameters and intestinal function in laying hens.

Abstract Different inclusion levels of cockroach meal Nauphoeta cinerea (CM) were investigated in diets for tilapia (Oreochromis niloticus) reared in biofloc systems in substitution of the soybean meal. Five treatments were evaluated (0, 5, 10, 15 and 20% of CM inclusion) using three experimental units per treatment. The experiment lasted for five weeks with units stocked with 10 juveniles (3.00±0.25 g) per replicate. Water quality, zootechnical performance, bacteriological profile, and proximate composition were analyzed and monitored. Zootechnical data was submitted to a regression analysis up to second order. No differences were verified regarding feed conversion, survival and productivity. The CM presented high protein levels (66.84%), high estimated gross energy (5270 kcal kg−1), low lipids (6.07%) and mainly long-chain saturated fatty acids. Different bacteriological profiles were identified including species which may be potentially pathogenic and responsible for degrading organic matter. The overall results indicated that it is possible to include CM up to 10% in diets for tilapia juveniles raised in biofloc systems.
