The cows were selected according to the following inclusion criteria: first calving cows and second calving cows. The results of live weight had numerical differences, the primiparous cows with 4...

This research aims to evaluate three levels of orange peel flour in the feeding of guinea pigs in gestation and lactation stages for 115 days distributed in empadre (32), gestation (68) and lactation (15). During the gestation stage, no significant differences were observed in the reproductive behavior of guinea pigs between the different levels of orange peel flour evaluated. This suggests that the inclusion of orange peel meal in the diet did not adversely affect the reproductive capacity o...

The objective of the present research was to evaluate three ovulation synchronization protocols in hair sheep applying the hormone Equine Chorionic Gonadotropin (eCG) at different times, the present research was developed in Estación Experimental Pastaza belonging to Escuela Superior Politécnica de Chimborazo; 15 selected hair sheep were used under identical nutritional, reproductive and sanitary conditions, the variables were evaluated: Initial weight (kg), Final weight (kg), Body condition ...

The quality of eggs plays a crucial factor for both those to be used for incubation and those to be used for human consumption and that it is not harmful to health. For this reason, this research analyzes the influence of different storage times of Creole hen (Gallus gallus) eggs on incubation and hatching rates, a critical aspect to optimize poultry production in Morona canton. The main objective was to evaluate how incubation and hatching rates vary as a function of egg storage times, provi...

Ecuador's river systems are subjected to daily discharges of large amounts of pollutants due to industrial and domestic activities. A common issue is the presence of anionic surfactants. This is widely used in various industries, which deteriorate water quality due to their properties such as emulsifying, detergent, and foaming characteristics. This situation is exacerbated by the lack of resource control and characterization. Therefore, the objective of this study was to evaluate contaminati...

Human activity generates many pollutants such as those produced by farm animal excreta, which negatively impact soil quality and contribute to climate change. This often leads to the frequent use of chemical products, a problem affecting the soil in the community of Llucud, in Chambo town. An alternative for managing these resources is the implementation of biodigesters, which convert animal waste into nutrient-rich fertilizer and biogas that can be used as fuel. Therefore, the research aims ...

Population and commercial growth have generated an organic waste overproduction in Sucúa, Morona Santiago. Currently, this waste is disposed of in a sanitary landfill, where part is used for composting. However, the amount generated exceeds the capacity of utilization. Therefore, this research aimed to evaluate compost production using the Takakura method as an alternative for organic waste sustainable management. The methodology combined qualitative and quantitative approaches, under a descr...

The research introduces the Amoush River water quality evaluation by identifying benthic macroinvertebrates for recreational use in Sinai civil parish. Three areas were established along the Amoush River, considering the morphological qualities of each monitoring point. From May to July 2024, 27 water samples were developed, analyzing physicochemical and microbiological parameters. In addition, water quality was estimated by calculating the ICA-NSF, and BMWP/Col indexes and determining the sp...

Water quality degradation is a global challenge that impacts human health, ecosystems, and economic development. Although water naturally contains some contaminants, human activities have significantly intensified its deterioration mainly by the introduction of chemicals and pathogens, increasingly affecting the available freshwater reserves. Therefore, the present investigation aimed to evaluate the spatial diversity of epilithic diatoms as indicators of water quality in the Tutanangoza Rive...

Air pollution caused by microscopic microorganisms is a growing concern that impacts the health of individuals in both enclosed and open spaces. ‘27 de Febrero’ market in Macas, Ecuador, presents poor infrastructure conditions, high humidity, and poor waste management, which causes microbiological contamination caused by pathogenic fungi, representing a significant risk to the environment and the health of individuals. The study aimed to evaluate the air quality in 2023 by identifying and qua...

Wastewater from municipal animal feedlots has a high concentration of organic material, which causes significant environmental pollution problems since they directly affect water resources, the environment, and the nearby population, causing diseases and affecting the physical integrity of the inhabitants.
