(average of 1.19 ± 0.09 kg/d) or energy-corrected milk yield (average of 27.2 ± 1.99 kg/d). Results of the current study suggest that the HS diet had a greater metabolizable energy and NEL content, increased partitioning of N toward milk secretion and away from urinary excretion, and may have increased partitioning of energy toward tissue energy deposited as fat. Osteoporosis is a disease of aging, characterized by a decrease in bone quality and a reduction in bone strength. Promoting the activity of osteoblasts is a useful strategy for combating the progression of osteoporosis. As a novel bone growth factor, lactoferrin plays a role in the anabolic activity in bone by inducing the proliferation and differentiation of osteoblasts and inhibiting the formation of osteoclasts. However, potential peptides with osteogenic activity from lactoferrin have not been identified. In the present study, a peptide with osteogenic activity-LFP-C, fragment residues 624 to 632, derived from lactoferrin hydrolysates-was identified using ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry and screened using molecular docking analysis. The LFP-C peptide significantly increased the proliferation of mouse cell line MC3T3-E1 and had a promoting effect on alkaline phosphatase activity and calcium deposition. Moreover, LFP-C increased the proportion of osteoblasts in the G2 and M phases. The osteogenic mechanism of LFP-C was also studied by molecular docking. We found that LFP-C could bind to the key domain (Lys13-Thr15-Gln16-Leu17-Gly18-Asp22) of epidermal growth factor receptor, a vital receptor tyrosine kinase that leads to the activation of the mitogen-activated protein kinase pathway. The main interaction forces were interpolated charge, hydrophobicity, and hydrogen bonding. Results indicated that LFP-C may play an osteogenic role in a similar way to lactoferrin, by promoting the proliferation and differentiation of osteoblasts. The findings of this in vitro experiment also demonstrated that the molecular docking method could play a role in the screening process; this in silico approach allowed for faster and cheaper identification of a promising bioactive component. The enterococci are ubiquitous bacteria able to colonize the human and animal gastrointestinal tracts and fresh and fermented food products. Their highly plastic genome allows Enterococcus spp. to gain resistance to multiple antibiotics, making infections with these organisms difficult to treat. Food-borne enterococci could be carriers of antibiotic resistance determinants. The goal of this work was to study the characteristics of Enterococcus spp. check details in fermented milk products from Poland and their antibiotic resistance gene profiles. A total of 189 strains were isolated from 182 dairy products out of 320 samples tested. The predominant species were Enterococcus faecium (53.4%) and Enterococcus faecalis (34.4%). Isolates were resistant to streptomycin (29.1%), erythromycin (14.3%), tetracycline (11.6%), rifampicin (8.7%), and tigecycline (8.1%). We also detected 2 vancomycin-resistant and 3 linezolid-resistant strains; however, no vanA or vanB genes were identified. A total of 57 high-level aminoglycoside resistance strains (30.2%) were identified, most of which have the ant(6')-Ia gene, followed by the aac(6')-Ie-aph(2″)-Ia and aph(3″)-IIIa genes. Resistance to tetracycline was most often conferred by tetM and tetL genes. Macrolide resistance was most frequently encoded by ermB and ermA genes. Conjugative mobile genetic element (transposon Tn916-Tn1545) was identified in 15.3% of the strains, including 96.3% of strains harboring the tetM gene. This study found that enterococci are widely present in retail ready-to-eat dairy products in Poland. Many isolated strains are antibiotic resistant and carry transferable resistance genes, which represent a potential source of transmission of multidrug-resistant bacteria to humans. Haplotypes that are common in a population but not observed as homotypes in living animals may harbor lethal alleles that compromise embryo survival. In this study, we searched for homozygous-deficient haplotypes in the genomes of 19,309 Nordic Red Dairy (RDC) and 4,291 Danish Jersey (JER) cattle genotyped using the Illumina BovineSNP50 BeadChip (Illumina Inc., San Diego, CA). For statistically significant deficient haplotypes, we evaluated the effect on nonreturn rate in at-risk matings (mating between carrier bull and daughter of carrier sire) versus not-at-risk matings (mating between noncarrier bull and daughter of noncarrier sire). Next, we analyzed whole-genome sequence variants from the 1000 Bull Genomes Project to identify putative causal variants underlying these haplotypes. In RDC, we identified 3 homozygous-deficient regions (HDR) that overlapped with known recessive lethal mutations a 662-kb deletion on chromosome 12 in RDC [Online Mendelian Inheritance in Animals (OMIA) 001901-9913), a missense muce the frequencies of lethal alleles in the population and to avoid at-risk matings. This study aimed to evaluate the perceptions and attitudes of artisanal cheese producers (n = 40) in Brazil regarding the implementation of traceability. A questionnaire consisting of 16 statements using a 5-point Likert scale was applied, and descriptive statistics and factor analysis were used for data analysis. The implementation of a traceability system can reduce the number of consumer complaints and the loss of products, in addition to increasing supplier control and process safety, thus protecting health and increasing consumer confidence. However, we did not find consensus on the relationship between implementation of a traceability system and rapid recalls in crisis episodes, or on the reduction in recalls and their negative impact on consumers. Because of the costs that drive implementation of this technology, some artisanal cheese producers do not consider a traceability system as a current reality to monitor their production. We concluded that Brazilian artisanal cheese producers have limited awareness of the impact of traceability implementation, which restricts investments in the system.
