Determinación de la edad gestacional mediante la medición de placentomas en vacas mestizas
(2024-08) Hernández Ocaña, Cynthia Ivette; Carrillo Álvarez, Israel Salomón
The determination of gestational age in cows has been an important tool in reproduction, since a better criterion in relation to gestational age in a cow was evident through the placentomes, seeking to be more efficient when detecting pregnancy. This study was developed at the Universidad Técnica del Norte. That is why exact data were collected from 42-60 days of gestation, measuring length 1.44 +0.38 and width 1.01 +0.25; 61-90 days length 2.29 +0.35, width 1.85 +0.5; 91-120 days length 3.1+0.14 and width 2.29+0.32 and 121-150 days length 3.24+0.10 and width 2.46+0.31. On the other hand, 46 pregnant cows (151-180 days) were also analyzed, length 3.60+0.15 and width 3.07+0.09; 24 pregnant cows (181-210 days) length 4.01+0.43 and width 3.16+0.13; 20 pregnant cows (211-240 days) length 5.23+0.63 and width 3.62+0.5; 25 pregnant cows (241-270 days) length 6.54+0.26 and width 4.99+0.46, in this case only data were taken from the caudal placentome due to the gestation time and the fetus is much more developed, the objective was to determine the age gestational with the measurement of placentomes in cows, it can be concluded that from the data obtained in the different stages of gestation a guide to understand days of gestation and the normal development of the fetus.
Elaboración de un plan de limpieza y desinfección pre-operacional en equipos e instalacionese del Camal Municipal de Ambato para mejorar la inocuidad de la carne
(Universidad Técnica de Ambato. Facultad de Ciencia e Ingeniería en Alimentos. Diplomado Superior en Auditoría y Aseguramiento de la Calidad para el Sector Alimenticio, 2013-06) Carrillo Álvarez, Israel Salomón; Almeida Secaíra, Roberto Ismael
Every plant food processor or packer must have a formal program of cleaning and disinfection to ensure I reduced risk of contamination removal microbiological, chemical and physical food. This program is essential for obtaining a food safe, harmless and quality. The Codex Alimentarius food safety guarantees, so that forces food companies hygiene programs, compared to that plan was designed Sanitation for Municipal Slaughterhouse Ambato. The work included the inventory of areas and equipment, was classified the type of dirt, we defined the type of product to use, documents established for the implementation and monitoring of the plan. Finally released to the slaughterhouse staff writing and proper training.
Estudio faneróptico, rendimiento y clasificación de las canales bovinas faenadas en el camal Municipal de la ciudad de Ambato
(2024-02) Paucar Naranjo, Dayana Michelle; Carrillo Álvarez, Israel Salomón
The objective of this research was to evaluate the phaneroptic characteristics, yield and classification of the carcasses of crossbred cattle slaughtered at the Municipal slaughterhouse of Ambato, the total sample was 500 cattle, of which 360 were Holstein crossbreeds, 361 males and 139 females, 236 of the animals had a body condition index 3, The phaneroptic characteristics of the cattle showed that the dominant coat color was bicolor with 408 animals, 366 cattle had black snouts and 225 black hooves, 80 females had pink udders and the scrotal color of the males was also pink with a total of 261 animals, finally 398 cattle had no umbilical fold and 471 had no dewlap. The average live weight was 327.26 kg, with males weighing 333.19 kg and females only 186.081 kg; with respect to carcass yield, there was an average of 50.28%, of which 51.30% in males and 28.31% in females. The Spearman correlation statistical analysis was highly significant *** p≤ 0.01 between the variables: phaneroptic (coat color, nose color, hoof color, udder color, presence of umbilical fold and dewlap), body condition and carcass yield of mestizo cattle slaughtered in the Municipal Camal of Ambato. Keywords: Cattle, Phaneroptic, Body condition, Live weight, Carcass yield, Carcass classification
Prevalencia de tricomoniasis en bovinos faenados en el centro de Faenamiento Municipal de Pastaza
(2024-10) Zúñiga Araujo, Solange Danniela; Carrillo Álvarez, Israel Salomón
Bovine trichomoniasis is caused by Tritrichomonas foetus, a protozoan species with wide worldwide distribution, causing a sexually transmitted disease in cattle that causes infertility, abortion and endometritis, postcoital pyometra or fetal maceration. In the present study, the prevalence of bovine trichomoniasis in cattle slaughtered at the Pastaza municipal slaughterhouse were determined. A total of 361 samples were taken from cattle admitted to the "Pastaza Municipal Slaughterhouse" from January to April 2024 from the Pastaza, Mera and Santa Clara municipalities. From these data, information on the relationship between the prevalence of the disease and the age, sex and origin of the animal was obtained. The study was carried out through simple random sampling and the data were analyzed using descriptive statistics, frequency and percentages. Additionally, the association of the variables sex, age and place of origin of the cattle with the prevalence of trichomoniasis was established through a Spearman correlation (𝜒 2 ). A general prevalence of trichomoniasis of 2.8% was found in cattle slaughtered in the municipal slaughterhouse of Pastaza, observed only in cattle from five parishes of the Pastaza canton with a total of 10 positive cases. No association was found between the sex, age group and place of origin of the cattle and the prevalence of trichomoniasis in this study. Given the importance of trichomoniasis, it is recommended to carry out studies using molecular biology to confirm the presence of the parasite in herds in the area.
