    (INGENIERO ZOOTECNISTA, 2022) AVEIGA ANDRADE JOSÉ FERNANDO ; ROMERO RIVAS FREDDY SEBASTIAN
    In the entrepreneurship modality thesis work, it was proposed to “carry out a feasibility study to implement a breeding system for red tilapia (Oreochromis sp) in geomembrane pools in Canton Chone Garrapata Site, in order to know if the activity is profitable or not. The study was carried out taking into consideration an intensive system, where five geomembrane tanks will be used, where the fingerlings will be placed per stage: fingerling, juvenile and fattening-harvest stage, the tilapias were sown by the stepped method, considering that This system allows to obtain a greater number of sowings and harvests per year, counting on an adequate aeration and water circulation system and avoiding losses in the tilapia rearing phases. Information was collected through a survey applied virtually due to COVID 19 problems to a certain sample of the urban population of the Canton Chone; the same ones that gave positive answers for the application of the study. A financial study was carried out where the investment flow was carried out for five years, obtaining a net flow of $ 16,243.74 US dollars; the cost benefit of the projected yielded a value of $ 1.01, which means that for every dollar invested, 0.01 cents will be obtained. The value of the NPV was $ 976.18 and the Internal Rate of Return (IRR) was 13%. With these results obtained, it is concluded that it is up to the interested parties to carry out this project as if it is feasible.

    In the current circumstances that humanity faces in the face of climate change, it is necessary to evaluate livestock systems in search of sustainability and sustainability, for decision-making in implementation. The present work was carried out in the Chone canton, Province of Manabí, located in the following coordinates: Latitude: 0° 40' 60" South, 80° 6' 0" West, with an average temperature of 27 °C, annual rainfall of 1400 to 1500mm. With the objective of determining the productive yields, botanical composition, nutritional content and agronomic variables of meadows arranged in two grazing systems grazing system: Voisin rational grazing and the continuous grazing system. The biomass yield was determined through gauging for the rainy and low-rain seasons, as well as agronomic variables, the botanical composition and the bromatological content of the predominant grass in each system, numerical data were obtained, with which referrals were obtained based on the specific objectives. The results showed a statistical difference between the rainy and low-rain seasons with respect to forage yield, highlighting the Voisin rational grazing system over continuous grazing, in relation to the agronomic variables and nutritional content, the superior results were found in the SPRV , for the Botanical composition, similarity was observed between the systems, however the SPRV as a whole was more favorable for the conditions of the plants, which would imply environmental services, greater digestibility, as well as better comfort for the animals. Keywords: grazing systems; agronomic variables; botanical composition; Nutritional value

    The use of fodder in the feeding of pigs brings with it nutritional and physiological advantages that favor the porcine behavior. The objective of this research consisted of evaluating the effect of the use of different levels of Morera flour in the feeding of pigs in the fattening stage, the same that was carried out in the swine farm of the Department of Animal Production of the Faculty of Zootechnical Sciences. The parameters evaluated were: daily food consumption (CDA), weight increase (IP), feed conversion (CA) and carcass yield (RDC). In the feed consumption of the pigs there was no significant difference, demonstrating a greater consumption with the inclusion of mulberry flour T1. Regarding the total weight increase from the beginning to the 45th day for the treatment T0 was 11,475 Kg - 37,5 Kg; T1 increased between 13.23 Kg 37.43 Kg; the T2: 13.54 Kg - 40.18 Kg, and finally the T3 treatment increased from 13.54 Kg - 38.84 Kg respectively. The averages of food conversion at 45 days were 2.88 Kg / Kg for T0. 2.87 Kg / Kg for T1. 2.64 Kg / Kg for T2 and 2.72 Kg / Kg for T3. Regarding the back fat there was no statistical difference at (P <0.05), the means between all the treatments were between 22.5 mm and 23.5 mm; being a good option the inclusion of mulberry flour to obtain better results on this measured parameter. The use of mulberry flour does not influence the sensory characteristics of pork, according to the data obtained through the application of a sensory test; because T1 is recommended.

    The porcine species is one of the species that reaches the highest population increases due to the number of offspring per birth and births per year; thus having high productivity. The objective was to evaluate the effect of the breed on the production and sperm quality of boars (Sus scrofa domesticus) in the Faculty of Zootechnical Sciences of the Chone canton, Ecuador. To contribute to genetic improvement and provide livestock technical knowledge carried out in a sperm evaluation system for stallions used in swine reproduction. A completely randomized experimental design with a factorial treatment arrangement was used: four breeds of breeding pigs (Pietrain, Duroc, Belgian and Landrace) between 8 and 9 months, average weight 120 kg and two concentrations of semen (pure and diluted). In 500 mL glass containers and with a funnel covered with a sterile gauze filter (separate solid and liquid fraction), the seminal sample was collected, immediately transferred to the laboratory and placed in a water bath at 36 ºC. For the macroscopic evaluation of the semen, the volume, color, odor and pH were determined, and in the microscopic agglutination, motility and sperm motility. The microbiological content of the ejaculate was determined by counting the colonies present. Results of macroscopic quality showed a higher ejaculate in the Pietrain breed, however in the parameters temperature, color, odor and pH no statistical differences were found. In the microscopic parameters, the Duroc breed showed greater motility and sperm concentration. The bacteriological quality shows the absence of Escherichia coli on the ejaculate of the pigs. In conclusion, the breed did not show a greater incidence on the sperm quality of the boars, which allowed guaranteeing semen with high genetic and sanitary value.

    The objective of this research was to evaluate the agronomic behavior, the nutritional content of Savoy Grass (Panicum maximum), Mombasa Grass (Megathyrsus maximum) and the botanical composition of the system during the rainy and dry seasons of the year. This research was carried out at the Hacienda San Pascasio, owner Econ. Jorge Flores de Valgas, located at the Baren site-kilometer 11.5 via Chone – Colorado – Balzar, Boyacá parish in the Chone canton, whose coordinates are S 0º36'24” W80º05 '37” with an altitude of 32 meters above sea level, at an average temperature of 29.1ºC, annual rainfall of 800 mm and a relative humidity of 78%, in an area of 78.39 Ha of which 68.62% is irregular terrain with slope of 50º and 31.38% belonging to flat land. For this study, agronomic, bromatological and botanical composition variables were considered, the applied methodology allowed the use of a completely random design, taking 5 samples at 5 different points in each of the 51 farm paddocks, during the two seasons of the year giving a total of 510 samples to determine the agronomic variables, later 15 samples taken in the summer time and 15 samples taken in the winter time were chosen randomly, giving a total of 30 samples to carry out the nutritional composition by means of bromatological analysis, Regarding the botanical composition, it was carried out using the method by counting individuals where 5 random samples were taken in the 51 paddocks throughout the year giving a total of 255 samples, prior to this they were identified and a count was made of each species that made up a sample including grass, each sample constituted an experimental unit. The results showed that the best performance during the year was obtained by Mombasa grass (Megathyrsus maximum) in terms of the agronomic variable Height of the Plant whose data is 149.72 cm, while during the dry season, Savoy grass (Panicum maximum) obtained the best result in the Stem Diameter variable with 1.07 cm, while for Plant Height it was Mombasa grass (Megathyrsus maximum) with a value of 151.27 cm, it can be seen that these grasses have moderately similar values. During the rainy season, as well as in the dry season, Mombasa grass (Megathyrsus maximum) stands out in Plant Height 148.16 cm, and in the Variable Number of plants with a value of 42.83, while the grass Savoy (Panicum maximum) presents lower values. In the bromatological results, the Savoy grass (Panicum maximum) reflects a better value during the year in terms of the Dry Matter variable 22.72, as well as in the FDN variable 69.54. During the year, the Mombasa Pasture (Megathyrsus maximum) stands out in the Dry Matter with a value of 20.59, as well as the Variable FDN 75.27. During the winter and summer season, both Pasture reflect similar values related to nutritional content. Regarding the Botanical composition associated with the area with Savoy Grass (Panicum maximum) this represented 55.70% while Mombasa Grass (Megathyrsus maximum) 46.15%.
