The time required to execute and defend undergraduate theses and the relationship between the number of theses supported with the scientific articles derived from theses that were published in indexed journals were analyzed. The study was carried out with theses work carried out at the Faculty of Veterinary Medicine and Zootechnics of the Universidad Nacional Micaela Bastidas de Apurímac in the period 2012-2018. The information available in the faculty and in the institutional repository of the university was collected. The publications indicated by the thesis advisers with the CTI-Vitae registry of the National Council of Science, Technology and Technological Innovation (CONCYTEC) and the publications available in international scientific databases were verified. Likewise, the date of approval of the thesis project and the date of defense of the thesis, the number of theses supported b...

The study was conducted in the district of Tamburco (Abancay, Apurimac, Peru) with the aim of comparing interpretation criteria of California Mastitis Test (CMT) in the diagnosis of subclinical mastitis in cattle. Two hundred and nine cows from a population of 459 hand-milked cows belonging to 95 breeders were used. A total of 828 functional mammary quarters were evaluated and the main criteria for CMT interpretation were estimated. The prevalence of subclinical mastitis in cows was 72.3 and 65.6%, and in total mammary quarters was 48.7 and 42.3% with and without considering traces as positives respectively, and without statistical difference. The estimated prevalence in individual mammary quarters varied between 48.3 to 49.3% and depending of the mammary quarter between 40.0 to 45.5% with and without considering traces as positives respectively (p<0.05). More intense positive reactio...

The aim of this study was to determine the effect of adding antioxidant Tempol in the individual and progressive motility of alpaca sperm at cooling and after thawing. Previously, the vas deferens was deviated in three males with suitable semen parameters. Sperm were collected three times per week and pooled to avoid the individual effect. The sample was distributed in four aliquots and placed in refrigeration to reach 5 °C in 2 h. The antioxidant was added in four concentrations: 0, 0.5, 1.0 y 1.5 mM when the aliquots reached 10 °C. The sperm were filled in 0.25 ml straws, placed over liquid nitrogen vapor by 6 min and then submerged. Individual motility at cooling was 55.1, 63.7, 52.8 and 45.0 (p<0.05) and after thawing 35.7, 42.3, 29.0 and 18.1% (p<0.05) for 0, 0.5, 1.0 and 1.5 mM Tempol, respectively. Progressive motility at cooling was 36.0, 42.4, 28.4 and 21.7 (p<0.05)an...

El presente estudio tuvo como objetivo determinar el efecto de la adición del antioxidante Tempol en la motilidad individual y progresiva a la refrigeración y descongelación de espermatozoides de alpaca. Se desvió el conducto deferente de tres alpacas con adecuados parámetros seminales y los espermatozoides fueron colectados tres veces por semana y mezclados para anular el efecto individual. La muestra colectiva se dividió en cuatro alícuotas y fueron colocadas en refrigeración hasta alcanzar 5 ºC en 2 h. El antioxidante fue añadido en concentraciones de 0, 0.5, 1.0 y 1.5 mM cuando las alícuotas alcanzaron los 10 ºC. Las muestras fueron envasadas en pajillas de 0.25 ml, colocadas sobre vapores de nitrógeno líquido por 6 min y sumergidas. La motilidad individual de refrigeración fue 55.1, 63.7, 52.8 y 45.0 (p<0.05) y a la descongelación 35.7, 42.3, 29.0 y 18.1% (p<0....

The study aimed to estimate five technological characteristics of the white fibre of Huacaya alpaca of a rural community of the Andean region of Apurimac, Peru. Fibre samples (n=405) were taken from the middle of the rib area prior to shearing. The variables studied were: mean diameter of fibre (MDF), coefficient of variation of fibre diameter (CVDF), comfort index (IC), curvature index (ICur) and spinning fineness (FiHi), by sex and age group according to teeth (DL=Deciduous teeth; 2D=2 permanent teeth; 4D=4 teeth; BLL=all teeth). The MDF for males and females was 19.6 and 20.1 µm respectively (p<0.05), where values increased with age (p<0.05). No statistical difference was found by sex or age for CVDF. The IC was 96.8% in males and 95.5% in females (p<0.05), decreasing with age (p<0.05). The ICur was similar between sexes and difference due to age was only observed between...

A study was carried out to determine the metabolizable energy (ME) and net energy (NE) of corn, wheat by-product, soybean meal, fishmeal, and soybean oil in poultry. 190 male chickens were used, distributed in six experimental diets (basal (B), B + corn (40%), B + wheat by-product (40%), B + soybean meal (30%), B + fish meal (30%), B + soybean oil (10%) with three feeding levels (ad libitum (AL), 85% AL and 70% AL). ME was determined by the total collection method of excreta and NE by the comparative slaughter method, the chickens received the experimental diets from 7 to 21 days of age, the excreta were collected every 24 hours (day 19 to 21). For NE, the energy retained and heat production were determined (7 and 21 days) The ME and NE of corn, wheat by-product, soybean meal, fishmeal and soybean oil was 3734, 2197, 2477, 3289, 8767 kcal / kg DM and 2527, 1598, 1417, 1837, 7550 kcal / k...

The aim of this study was to quantify and characterize the undergraduate theses of the Faculty of Veterinary Medicine and Zootechnics (FMVZ) of the Universidad Nacional Micaela Bastidas de Apurímac (UNAMBA), Peru. All of the theses defended in the period 2012-2018 were reviewed. A survey was carried out among the thesis supervisors regarding the publications derived from the theses. Descriptive statistics were used to determine the frequencies and proportions. Besides, multiple correspondence analysis to estimate relationships between the variables and their categories were conducted. Of the 79 registered theses, the highest number of dissertations were done in 2018 (29.1%), the two main areas of research were animal production (54.4%) and public health (24%), the highest number was done on bovines (21.5 %), alpacas (16.5%) and dogs (16.5%), and 72.2% of the theses correspond to observa...

The experiment was carried out in Tamburco, province of Abancay, Peru with the objective of determining the effect of diets based on pisonay (Erythrina sp) on the concentration of tannins and total alkaloids, the serum concentration of the aminotransferases, the lesions in the liver and the liver/liveweight ratio of the guinea pigs. Leaves and petioles of pisonay were used with four months of regrowth and fresh alfalfa (Medicago sativa) with 28 days of regrowth in the diet of 24 improved male guinea pigs, distributed in three treatments: diet A100: 100% alfalfa (80 g), diet A50P50: 50% alfalfa (40 g) plus 50% pisonay (40 g) and diet P100: 100% pisonay (80 g). The feeds were supplied twice a day. Serum levels and liver/liveweight ratio were analysed with complete random design, the effect of diets on guinea pig liver lesions was analysed with Fisher's exact test. The concentration of tann...

The study aimed to determine the chemical composition and ruminal degradability of dry matter (DM) and crude protein (CP) of Erythrina falcata at 105, 120 and 135 days of regrowth. Leaves and petiole samples were dried and 8 g of dry grounded samples were placed in nylon bags in the rumen of three male goats during 0, 24, 48 and 72 hours. The DM and CP values were 24.4 and 21.4% at 105, 24.8 and 23.2% at 120 and, 27.2 and 24.4% at 105 days respectively. The ruminal degradability of potentially degradable insoluble fraction of DM and CP was 29.6 and 42.9% at 105, 24.3 and 31.4% at 120 and, 14.9 and 24.1% at 135 days, respectively, and the effective degradability of DM and CP was 41.3 and 41.2% at 105, 36.5 and 30.3% at 120 and, 32.3 and 30.5% at 135 days respectively. The study showed a higher protein advantage in goats at 105 days of growth of E. falcata foliage.

The creole cattle was originated after the introduction of cattle into America 5 centuries ago. Currently, the production traits of Peruvian creole cattle is scarcely known. An important characteristic of the creole cattle is its adaptability to different extreme environments. However, to date, molecular studies in Peruvian creole cattle are still scarce. Currently, due to the advances in molecular genetics, a new generation of molecular markers has been developed for the genetic characterization of livestock. Single nucleotide polymorphisms (SNP) have become a very popular tool for the genetic study of livestock populations. Genome-wide SNP chips were developed for multi-breed genetic studies in cattle.
