The objective of this study was to evaluate the effect of the inclusion of jackfruit pulp (<em>Artocarpus heterophyllus</em> Lam) powder in the diet of Rhode Island Red hens on egg quality. Thirty 34-week-old hens were used, distributed in two treatments (control and 6 % jackfruit pulp), which were fed for 6 weeks. Feed consumption, weight gain, laying percentage and egg quality were determined. The results indicate that the inclusion of jackfruit pulp in the diet for laying hens improved laying percentage and there was color modification in the L* and b* values, without causing eggshell fracture problems. Due to the above mentioned, it is concluded that jackfruit pulp is a good alternative for the feeding of laying hens, since it does not negatively affect their productive parameters and improves egg yolk quality.</p> Brenda Yanelis Diaz Martínez Liliana Ortega González Maricela Ayala Martínez Sergio Soto Simental Copyright (c) 2025 Licencia CC Reconocimiento-NoComercial 4.0 Internacional (CC BY-NC 4.0) https://creativecommons.org/licenses/by-nc/4.0 2025-02-25 2025-02-25 47 //cu id.com/2248/v47e01 Helminths and economic losses due to condemnation of food animals in Cajamarca, Peru https://revistas.censa.edu.cu/index.php/RSA/article/view/1366 <p>Under optimal environmental conditions for animal husbandry, parasites that adversely affect animal productivity also thrive. This study evaluated the presence of parasites and estimated economic losses due to the condemnation of viscera from cattle, sheep, and swine, which were slaughtered in Cajamarca, Peru. Viscera and carcasses from 2,810 cattle, 3,267 sheep, and 3,858 pigs were inspected. In cattle, <em>Fasciola hepatica</em> was found in liver (77.54 %), hydatid cyst in liver (0.18 %) and lung (0.07 %) and <em>Dictyocaulus</em> spp. in lung (0.04 %). In sheep, <em>F. hepatica</em> (50 %), hydatid cyst (0.03 %), <em>Thysanosoma actinioides</em> (0.10 %) and <em>Cysticercus tenuicollis</em> (0.12 %) were found in the liver. In swine, <em>F. hepatica</em> was found in liver (2.64 %), lesions by <em>Ascaris suum</em> (12.36 %) and <em>C. tenuicollis</em> (0.75 %), hydatid cyst in liver (0.16 %) and kidney (2.72 %), <em>Cysticercus cellolosae</em> in carcass-tongue-heart (0.05 %) and <em>Metastrongylus</em> spp. in lung (1.48 %). Total economic losses per species were USD 28,971.90 in cattle (annual economic loss [AEL]: 173,831.38), USD 4,051.30 in sheep (AEL: 24,307.79), and USD 2,013.90 in swine (AEL: 12,083.39). Total losses attributable to <em>F. hepatica</em> amounted to USD 33,184.89 (AEL: 199,109.32), <em>A. suum</em> to USD 1,191.63 (AEL: 7,149.80), <em>C. cellulosae</em> to USD 354.78 (AEL: 2,128.67), hydatid cysts to USD 287.70 (AEL: 1,726.22), <em>T. actinioides</em> to USD 7.43 (AEL: 44.57), <em>Dictyocaulus</em> spp. to USD 5.54 (AEL: 33.22), <em>Metastrongylus</em> spp. to USD 3.71 (AEL: 22.24), and <em>C. tenuicollis</em> to USD 1.42 (AEL: 8.52). The overall economic loss across all three species totaled USD 35,037.09 (AEL: 210,222.56). It was concluded that <em>F. hepatica</em> was highly prevalent and caused the greatest financial losses in cattle and sheep, while <em>A. suum</em> led to significant losses in swine. The presence of hydatid cysts and <em>C. cellulosae</em> represents a public health concern.</p> José Ruiz Juan Rojas-Moncada Berardo Escalante Teófilo Torrel Luis Vargas-Rocha Copyright (c) 2025 Licencia CC Reconocimiento-NoComercial 4.0 Internacional (CC BY-NC 4.0) https://creativecommons.org/licenses/by-nc/4.0 2025-02-10 2025-02-10 47 //cu id.com/2248/v47e03 Bacterial diversity in goat milk with clinical mastitis in Ecuador https://revistas.censa.edu.cu/index.php/RSA/article/view/1367 <p>Mastitis is an inflammation of the mammary gland that significantly affects goat milk production and quality, leading to economic losses for Ecuadorian farmers. This study aimed to research the bacterial diversity associated with clinical mastitis in goats from Ecuador. Milk samples were collected from goats showing macroscopic evidence of clinical mastitis for subsequent DNA extraction. The 16S rRNA gene was amplified and sequenced using Illumina MiSeq technology for metagenomic analysis. Sequences were quality filtered and clustered into Zero-radius Operational Taxonomic Units (zOTUs). They were then taxonomically grouped to classify the bacterial species present in the milk. The analysis revealed a high diversity of bacterial communities, with 550 zOTUs belonging to 12 phyla. Proteobacteria and Firmicutes emerged as the predominant phyla, harboring diverse families which include: Enterobacteriaceae (<em>Proteobacteria</em>) and Staphylococcaceae (Firmicutes). Notably, a significant portion (86.91%) of the zOTUs identified belonged to families with unknown functionalities related to mastitis. These findings offer an initial and valuable overview of the bacterial diversity associated with clinical mastitis in goats, as well as highlighting the potential presence of uncharacterized mastitis-related bacteria that could be relevant for this disease. Future studies focusing on species level identification and functional characterization are needed to develop strategies for the prevention and control of mastitis in Ecuadorian goat production.</p> Cristhian Sagbay Díaz Oscar Vivanco-Galván Luis Rodrigo Saa Froilán Garnica Marquina Cristòfol Peris Ribera Paulo Herrera Copyright (c) 2025 Licencia CC Reconocimiento-NoComercial 4.0 Internacional (CC BY-NC 4.0) https://creativecommons.org/licenses/by-nc/4.0 2024-12-18 2024-12-18 47 //cu id.com/2248/v47e04 Quality indicators of Queen Conch (Aliger gigas) dough processed by Cuban fishing industries https://revistas.censa.edu.cu/index.php/RSA/article/view/1368 <p>This research aimed to evaluate the quality indicators (in seven batches) of conch dough processed by Cuban fishing industries during the year 2022. For this purpose, hygiene and pathogenic microorganisms were determined according to NC 585: 2017, and the nutritional value. In addition, a quantitative descriptive analysis of the product was carried out. . A correlation was established using the Spearman Coefficient between the levels of mesophilic aerobes in the conch dough and its sensory quality. Of the seven batches analyzed, 58 % were within the permissible range for mesophilic aerobes, as established in the standard. The presence of <em>Salmonella</em> spp. was observed in one of the batch. . All samples were free of <em>E. coli</em>, <em>Vibrio cholerae</em> and <em>Vibrio parahaemolyticus</em>. With respect to the sensory analysis, 85.7 % of the batches were rated as excellent and very good. Nutritional values: 75.5 % moisture, 1.5 % ash, 14.9 % protein, 0.5 % fat, 7.6 % carbohydrates, and an energy value of 95 Kcal/g were obtained. Batches 1, 3 and 6 presented excellent quality indicators. There was a negative correlation between the levels of mesophilic aerobes in the conch dough and color, flavor and texture, being the odor attribute the most influential.</p> Whitney Sixela Rodríguez Fuertes Yeniset Fumero Acosta Ideilys Barrios Puentes Ileana Olivares Oceguera Raquel Silveira Coffigny Wendy de la Caridad Ramos Pereiro Manuel Rubio Limonta Copyright (c) 2025 Licencia CC Reconocimiento-NoComercial 4.0 Internacional (CC BY-NC 4.0) https://creativecommons.org/licenses/by-nc/4.0 2024-11-09 2024-11-09 47 //cu id.com/2248/v47e05
