Influence of goat management systems on hematological, oxidative stress profiles, and parasitic gastrointestinal infection

Abstract

Background and Aim: Good management in goats is known for good quality health and increasing productivity. The physiological change studies in goats are limited despite some existing studies on the relationship of various patterns to growth rates. This study aimed to determine the hematological parameters, oxidative stress, and parasitic infection in three management systems in Thai native goats. Materials and Methods: A total of 18 male goats were randomly assigned to the three systems: The free-range model (FREE), the semi-intensive model (SEMI), and the kept-in-a-cage model (BARN) for 35 days. Blood, fecal sampling, and weight data were collected and monitored every 5 days for analysis. Results: No statistical differences were found in the FREE and SEMI groups, but significance was observed in the BARN group. The body weight of the goats gradually reduced from 13.0 ± 2.44 kg to 10.18 ± 2.61 kg (mean ± standard deviation). In contrast, the significantly increasing red blood cells, packed-cell volume, white blood cells, neutrophil-to-lymphocyte (N/L) ratio, cortisol hormone, and antioxidation profiles were observed to be higher in BARN than in FREE and SEMI groups. The intensity of the parasite eggs was remarkably significant. It was observed in the BARN group between the beginning and end of the experiment (supported by a high level of eosinophils). Conclusion: These data can be applied for the realistic evaluation and improvement of management practices, especially fully restrained management (BARN) for monitoring the health status of goats. Keywords: goat, hematology values, management systems, oxidative stress, parasites.

Appraisal of Restraint Positions for Rumen Skin Clamp Fixation, Stay Suture, and Mobile Small Ruminant Surgical Chute Rumenotomy Based on the Haematology of Kano-Brown Goats

“…Impliedly, in response to the different surgical techniques used in groups A, B, and D, the goats might have activated compensatory mechanisms to maintain homeostasis, preventing significant alterations in hematological parameters, much so close to the findings of Alvites et al (2021), who observed in their study reviews which summarized the general principles related to the use of small ruminants as animal models for scientific research. A study by So-In and Sunthamala (2023) on housing systems used for goat management highlighted similar influences on hematology, and stress profiles in goats. Although the surgical technique for rumenotomy differed between groups A and B of the same lateral recumbency restraint position, it is possible that the variation in technique did not have a substantial impact on the measured hematological parameters.…”

The protective effect of Thai rice bran on N-acetyl-ρ-aminophen-induced hepatotoxicity in mice

“…After that, the samples were heated to a 15-min boil. The thiobarbituric acid-reactive species was measured with a spectrofluorometer that was calibrated to emit at 551 nm and excite at 528 nm ( 32 ).…”

Effects of Dietary Selenium Yeast Supplementation in Pregnant Cashmere Goats on the Development of Offspring Hair Follicles

“…Improvements in nutrition during fetal hair follicle formation are important for increasing secondary hair follicle size, depth, and density. Maternal nutritional deficiency and oxidative stress damage during pregnancy, including a hightemperature environment and insufficient maternal oxygen supply, adversely affect the development of fetal secondary hair follicles [6][7][8]. In practice, a series of problems, such as bad environmental conditions, single forage types, and extensive feeding management, can lead to the oxidative stress of goats, resulting in an increase in free radical generation in the body and, subsequently, a change in the physiological state [7,9].…”
