J. Selva Andina Anim. Sci. 2022; 9(1):3-14. In The objective of the study was to evaluate the use of garlic (A. sativum) in the prevention of saprolegniosis in rainbow trout (Oncorhynchus mykiss). Descriptive statistics were applied. We used juvenile fish distributed in 10/pond, in 15 ponds, 150 specimens (fish from 10 to 15 cm in length, with weights from 150 to 200 g), there were positive controls with symptoms of saprogneliasis and one negative individual in optimal health conditions. Once the crude garlic extract was elaborated with the determined samples, the results were: the presence of fungal structures in the form of cotton specks based on the appearance of this sign in T1 11, T2 13 and T3 15 trouts respectively affected and it was analyzed during the garlic treatment the reduction and complete absence of the sign we have for T1 22, T2 35 and T3 33 with frequency and representing 24 %, 39 % and 37 % respectively obtaining better results T2 based on 500 mg of crude garlic extract. The depigmentation of the skin is another sign of Saprolegnia presence which was manifested in all fish and analyzing its reduction and absence throughout the treatment, results were obtained in T1 and T2 with frequencies of 59 each, representing 33.5 %, and T3 with a frequency of 58 representing 32.9 %, the three treatments showed efficacy since there is no significant percentage difference. It is concluded that the analysis of Saprogneliasis by Saprolegnia spp. determined that T2 (500 mg/L water/tank) was the one that controlled macroscopic lesions of Saprolegnia spp. 2022.

The objective of the research was to evaluate the influence of two voltages in the electroejaculation protocols on the seminal quality of alpacas ( Vicugna pacos ). t was developed in the Reproductive Biotechnology Laboratory, Salache Academic Experimental Center, Technical University of Cotopaxi. Eight male alpacas were used and from each one two ejaculates were collected weekly, one using the electroejaculation protocol that used several 10 volt stimuli, and the other using a protocol where the stimuli were 12 volts. The volume of the ejaculated determined itself for direct observation in measuring glass, la concentration; sperm motility, viability and morphology by Neubauer chamber, DM4B YDM6B mass microscope at 10X, Eosin-Nigrosin staining and observation of semen-eosin staining, respectively. Volume, concentration of ejaculates, motility, seminal pathologies were compared according to the electroejaculation protocol by means of the Student's t test for independent samples. The volume of the ejaculates was 0.75±0.20 and 1.10±0.39 mL, the concentration 2.12±1.93 and 2.25±1.89 (x10 6 ), the sperm mass motility 81. 25±11.81 % and 80.00±14.14 %, mortality 17.50±9.57 and 15.00±10.80 % and morphoanomalies 12.50±6.45 and 13.50±8.01 % in the animals that received electroejaculation with 10 and 12 volts, respectively. There were no significant differences (p> 0.05) in the seminal parameters evaluated according to the voltage used in the ejaculation protocol. It is concluded that the increase in voltage in the electroejaculation protocol had no influence on the seminal quality parameters of alpacas

J. Selva Andina Anim. Sci. 2022; 9(1):23-36. In The objective of the research was to describe quantitative genetics and breeding principles in animals destined for livestock production. Economically important characteristics, such as body weight gain, egg, milk, and meat production rate are quantitative or metric typologies, traits with continuous variability. The action of addictive genes tends to originate a normal phenotypic distribution between the means of two progenitor populations, while multiplicative genes create geometric series governed by genes with multiplicative action. In addition, it should be considered that the most important factor in the creation of effective breeding techniques to optimize the genetic quality of animals is heritability, as they contain all types of gene action. In addition, parametric and non-parametric methods offer us a solution that becomes helpful or appealing to the questions that arise from the research and testing of hypotheses that are presented, we should also mention the models that explain the action of genes, such as breeding value and selection and production ability. Animal producers apply selection following several criteria in parallel as mating methods (panmixia, inbreeding, and heterosis). Finally, the application of breeding processes leads to a sensible selection by mating with special intentions without restrictions. 2021. Journal of the Selva Andina Animal Science. Bolivia.

Juan Carlos Martínez-González E-mail address: jmartinez@docentes.uat.edu.mx The honey bee (Apis mellifera) has been the most widely used bee due to its pollination and honey production capacities. Currently, beekeeping encompasses several health problems, which have drastically affected the populations of beehives in production. Among the diseases affecting bees are: American foulbrood, European foulbrood, limebrood, stonebrood, nosemiasis, acariosis and varroasis, among others. The Varroa destructor mite, which acts as a vector of different diseases and is recently associated with colony collapse syndrome. This mite affects bees during the phoretic and reproductive phase. However, the indiscriminate use of synthetic acaricides, in addition to having a harmful impact on the environment, affects the safety of products derived from the hive. In addition, they have originated resistance in V. destructor populations. This has forced the development of new strategies and treatment alternatives, such as the use of various plants native or endemic to the region (milling, extracts, oils and/or dehydrated powdered extracts). Plant essential oils are volatile aromatic compounds, mainly terpenoids, phenylpropanoids, monoterpenes, sesquiterpenes and alcohols, which have a wide range of antimicrobial and antioxidant activity, so the addition of essential oils of clove, eucalyptus, mint, rosemary, oregano and cinnamon can be beneficial in the apiary. The uses of these products can minimize production costs, encouraging producers to use these products.

In this study, the behavior of ginger flour ( Zingiber officinale ) was evaluated on the productive parameters during the first stage of laying in quail (Coturnix coturnix japonica), it was carried out in five phases distributed in weeks (phase one, 1 and 2, phase two, 3 and 4, phase three, 5 and 6, phase four 7 and 8 and phase five 9 and 10) of posture. The variables to be studied were: feed consumption (g) feed conversion, mortality, (%), percentage of laying (%), egg quality expressed in (egg weight (g) shell thickness (mm), resistance of shell (kgf), yolk coloration. A completely randomized design with four treatments and six repetitions was used, as well as an analysis of variance and Tukey's test at 5%. The treatments used were: T 1 , T 2 and T 3 T 0 (control), were applied in doses of ginger flour of: 0%, 0.2%, 0.4% and 0.6% respectively. The statistical differences between T 3 and the control group, determined that the flour favors the consumption of food, especially in the final phases of the study, (T 1 , T 2 and T 3 ) compared to the control group. Feed conversion shows significant differences with T 2 in the interme-diate production phases compared to the control. The percentage of laying does not present significant differences, in addition to the quality of the eggs improved notabl e mind. Regarding mortality, there were significant differences especially in T 3 compared to the control since the birds showed resistance to diseases. In relation to profitability, the results of T 3 were superior, with a CRB of 1.19. Concluding that the inclusion of ginger flour improves the productive parameters and the quality of the eggs essential on growth antioxidant and cholesterol status
