الوصف: Large-scale pig farming is associated with the production of large amounts of animal excrement, which, after processing into the form of, e.g., slurry, are managed on agricultural land as natural fertilizers. The utilization of pig manure on agricultural land in an excessive and uncontrolled manner may pose a threat to zoonoses due to the significant amounts of potentially pathogenic microorganisms within its content. This study aims to determine the impact of the methane fermentation process carried out in two agricultural biogas plants on the efficiency of sanitization of pig slurry, input biomass, and digestate. The biogas plants differed in terms of the substrate used; one used pig slurry from a maternal (breeding) farm (BP-M), and the other utilized pig slurry from a fattening farm (BP-F). The physicochemical analyses showed that the slurry, input biomass, and digestate from the BP-F were characterized by a significantly higher contents of organic dry matter, ash, and ammonium nitrogen than the slurry, input biomass, and digestate from the BP-M. The parameters of the methane fermentation process, including temperature and pH, reached higher values in the BP-F compared to the BP-M. The microbiological analyses led to the conclusion that the efficiency of sanitization of input biomass, including pig slurry, was significantly higher in the BP-F compared to the BP-M. Due to the above findings, locating biogas plants near pig fattening farms should be recommended.

مصطلحات موضوعية: crossbred sows, gestation length, reproductive performance, Zoology, QL1-991
الوصف: The aim of the study was to analyse gestation length in sows raised on a large-scale pig farm and its effect on the sows’ reproductive performance. The study was carried out on a total of 556 litters from 92 crossbred sows from the DanBred pig breeding company, obtained by crossing the breeds Danish Landrace and Danish Yorkshire. The research material was divided into 6 groups depending on the length of gestation: group I – gestation length 115 days, group II – 116 days, group III – 117 days, group IV –118 days, group V – 119 days and group VI – 120 days. The analysis showed that the average gestation length was 117.6 days, with the shortest pregnancy lasting 113 days and the longest 121 days. Among all cases analysed, the most (37%) were those in which the gestation period lasted 118 days. The length of the gestation period was found to influence the number of piglets born dead or mummified, the weaning-to-service interval, and lactation length. Moreover, the length of the gestation period was found to affect that of the following gestation.

الوصف: Natural substances of plant origin play an important role in the protection of animal health and the improvement of the quality and health safety of food products of animal origin. The research was carried out to determine the effect oregano essential oil, as a feed additive on the production effects, quality and chemical composition of meat, as well as on the level of selenium in pig tissues and selected serum biochemical indicators. The study did not show a significant effect of the preparation containing oregano oil used in the feeding of fattening pigs on the body weight of fattening pigs, their growth rate, as well as feed intake and utilization. Chemical analysis showed that pigs receiving the addition of oregano oil achieved significantly higher (p0.05) content of dry matter and protein in the Longissimus dorsi (LD) muscle. The LD muscle colour assessment showed that supplementation of the pig diet during the fattening period with oregano oil had a significant effect on the yellow colour component of meat (higher b* values; p0.05). Supplementation with oregano oil contributed to a significant reduction in serum triglyceride concentration (p0.05). The results of this study suggest that supplementation of the pigs' diet with oregano oil contributes to the increase in the yellowness of meat and the content of dry matter and protein as well as to the decrease in the concentration of triglycerides in the serum.

الوصف: Prophylactic use of antibiotics in-feed has been effective in decreasing the incidence of diarrhea in weaning piglets. However, the overuse of antibiotics as prophylactic or therapeutic agents in animal feed leads to the evolution of drug-resistant bacteria and antibiotic residues in pigs. This study investigated the effects of Bacillus licheniformis-fermented products on diarrhea incidence and the fecal microbial community in weaning piglets. A total of 120 crossbred piglets with an average initial body weight of 9.87 ± 1.43 kg were randomly allotted to four dietary treatments consisting of three replicate stalls with 10 piglets in each. The dietary treatments comprised a basal diet as control, control plus 1 g/kg or 4.5 g/kg of B. licheniformis-fermented products, and control plus 30 mg/kg antibiotics (bacitracin methylene disalicylate). Results showed that 4.5 g/kg of B. licheniformis-fermented product supplementation significantly reduced diarrhea incidence in weaning piglets. Principal coordinate analysis and a heatmap of species abundance indicated distinct clusters between the groups treated with antibiotics and B. licheniformis-fermented products. The bacterial richness and evenness in the feces decreased in weaning piglets fed 1 g/kg of B. licheniformis-fermented products and antibiotics. The abundance of the genera [Ruminococcus] gauvreauii group, Ruminococcaceae UCG-005, and Ruminococcaceae UCG-008 in the feces decreased in weaning piglets fed B. licheniformis-fermented products or antibiotics. The average abundance of the genus Prevotella 9 in the feces was positively correlated with the concentration of B. licheniformis-fermented products and negatively correlated with the diarrhea incidence in weaning piglets. Furthermore, the average abundance of the genus Prevotella 9 in the feces was positively correlated with the growth performance of weaning piglets. These results demonstrate that B. licheniformis-fermented products can improve diarrhea incidence and fecal microflora composition in weaning ...

الوصف: Celem pracy była ocena wpływu uzupełniania standardowych mieszanek paszowych dla tuczników dodatkowymi ilościami selenu i witaminy E na wyniki tuczu, skład chemiczny mięsa i parametry biochemiczne surowicy tuczników. Badania przeprowadzono na 60 tucznikach linii 990. Zwierzęta przydzielono do 4 grup: grupa kontrolna (CG) otrzymująca mieszankę pełnoporcjową zawierającą 0,3 mg Se (Na2SeO3) i 60 mg witaminy E · kg–1; grupa SE - otrzymująca dodatek 0,2 mg organicznego Se · kg–1; grupa VE - otrzymująca 60 mg witaminy E · kg–1; oraz grupa VE + SE - otrzymująca dodatkowo 60 mg witaminy E · kg–1 i 0,2 mg organicznej Se · kg–1. Badania wykazały, iż żywienie tuczników zwiększoną ilością selenu i witaminy E, może nieznacznie pogorszyć wykorzystanie paszy i mięsność, ale obniża zawartość cholesterolu w surowicy oraz mięsie tuczników.

الوصف: The study was aimed at defining leptin gene polymorphism and its potential association with values of particular features of fattening and slaughter value of gilts of Line 990. The study included a total of 208 gilts. The polymorphic locus in LEP gene was identified by the restriction enzyme HinfI in 3469 position, by using the polymerase chain reaction-restriction fragment-length polymorphism (PCR–RFLP) method. Two alleles of LEP gene were identified: T (0.94) and C (0.06), resulting in two genotypes: TC (0.12) and TT (0.88). We did not observe any gilts of CC genotype. The analysis of values of fattening and slaughter features, depending on LEP genotype did not reveal significant differences in body mass increase, daily gain from day 63 to 180, and daily gain from birth to day 180, feed conversion per 1 kg body mass and the loin-eye thickness. Significant differences between the LEP genotypes were present for such features as the backfat thickness at points P2 (p ≤ 0.05) and P4 (p ≤ 0.01) and average backfat thickness (p ≤ 0.01) in favour of TT genotype. We noted higher average values of lean meat content in carcass in favour of TT homozygotes, compared to the heterozygotes (p ≤ 0.05). The investigation contributes additonal information regarding LEP gene polymorphism in gilts of Line 990. Knowledge of LEP genotypes may be useful to improve the slaughter value in gilts

الوصف: The relationship between blood serum and seminal plasma cholesterol concentration and semen traits and testes size was examined on 110 young boars (6 month old) of the 990 synthetic line. In the study were determined: testes volume, semen quality traits (ejaculate volume, motile spermatozoa percentage, spermatozoa concentration and total number per ejaculate, percentage of spermatozoa with normal acrosome, percentage of spermatozoa with major and minor morphological defects, osmotic resistance test value [ORT] and activity of aspartate aminotransferase in seminal plasma [AspAT]). Cholesterol content in blood serum and seminal plasma were determined. Mean cholesterol content in blood serum amounted to 71.2, while that in seminal plasma to 6.96 mg/dL. Total cholesterol content in blood serum correlated positively with testes volume (P≤0.05), whereas no correlation was found with semen quality traits of the examined males. Cholesterol concentration in seminal plasma was positively correlated (P≤0.05) with spermatozoa motility, concentration and total number, while negatively (P≤0.05) with the percentage of spermatozoa with major morphological defects and the activity of AspAT in seminal plasma. No relationship was found between total cholesterol content in blood serum and that in seminal plasma.

الوصف: The study involved 110 hybrid grower-finisher pigs from Polish Large White x Polish Landrace sows sired by Pietrain breed boars and their crossbreds with the 990 line and Duroc. The aim of the study was to determine an association of the polymorphism of RYR1, myogenin (MYOG) genes and carcass meatiness level with carcass slaughter value and meat quality traits in hybrid pigs. Better meat quality was found in pigs of CC genotype at locus RYR1 than in those of CT genotype, with a similar carcass slaughter value and meat chemical composition. No significant differences were found in meat traits (carcass slaughter value) and quality between AA and AB genotypes at locus MYOG. Similarly, no significant differences were found between carcass meatiness ranges adopted in meat quality and its chemical composition, except for water holding capacity, which was higher in pigs with ⪬ 54% meatiness than in those with > 54%. Moreover, interaction was found between carcass meatiness range and RYR1 genotype in relation to backfat thickness and intramuscular fat content, as well as a connection between carcass meatiness range and MYOG genotype in relation to water-soluble protein content. The results indicate the need to continue selection work towards the elimination of allele T RYR1 gene’s in pedigree herds to improve meat quality in fatteners.

الوصف: The aim of this study was to evaluate the effect of dietary L-carnitine supplementation either with or without extra Fe supplementation from Fe-amino acid (Fe-AA) complex on body weight gain, feed conversion, carcass characteristics and blood metabolite concentrations in fattening pigs. The study was carried out with 75 fatteners (30.100 kg body weight), divided into three groups, of 25 pigs each. The control group was given a basal diet that contained 85 mg/kg of Fe from premix. A L-carnitine group was given a basal diet supplemented with 100 mg/kg of L-carnitine, and a L-carnitine+Fe group was given a basal diet supplemented with 100 mg/kg of L-carnitine and 60 mg/kg of Fe from a Fe-AA complex. The supplement of L-carnitine to the diets did not have any effects on the growth performance and carcass traits. The L-carnitine supplement decreased the concentration of triglycerides (p.0.05), cholesterol (p .0.05) and low-density lipoproteins (p .0.01) in the blood serum of pigs, while it increased (p.0.01) the concentration of high-density lipoproteins. The combination of L-carnitine+Fe increased the growth performance of growing pigs (p .0.05) and the lean percentage and fatless ham weight in carcass and also increased (p .0.05) the Fe content in the blood serum and the longissimus dorsi muscle of pigs. The results suggest the more effective outcomes can be reached when L-carnitine+Fe rather than only L-carnitine is used in diets.

The investigation contributes additonal information regarding LEP gene polymorphism in gilts of Line 990. Knowledge of LEP genotypes may be useful to improve the slaughter value in gilts primarily due to less fatness. Due to the lack of individuals representing CC genotype in our results, research should continue on a larger population.
