The impact of subjecting Turki-Qashqai goats to elevated thermo-humidity index under different nutritional systems on their performance, blood metabolites, and oxidative status |
|
| چکیده انگلیسی مقاله |
Due to scarce research on how exposure to hot climates and different feeding schedules affects the oxidative status of nomadic animals a study was conducted with 66, 3 to 4 years old female Turki-Qashqai goats, weighing an average of 41.50±4.75 kg (mean ± standard error), and milk yield of 1.18±0.31 kg in a factorial experiment with a complete randomized design as a basic design. The goats were randomly divided into three groups: 1- natural pasture fed (M), 2- natural pasture in addition to 500 g of concentrate per day (MS), and 3- natural pasture hay along with 500 g of concentrate (AS). The experimental phase commenced on April 20th and concluded on June 20th. The collected data underwent statistical analysis using the mixed procedure of SAS. The body condition score was similar across all experimental groups during spring, but a notable decline was observed in summer within the pasture group. During the summer season, feed intake experienced a significant decrease compared to spring. Seasonal variations had a notable impact on milk production and fat-corrected milk (FCM) levels, as anticipated. The spring season exhibited the highest values in both aspects. The concentration of ROMs was affected by the season, diet, and the interaction of them. GPx and SOD showed increased activity in summer when compared to spring. Moreover, α-tocopherol levels were higher in spring than in summer. The results from this study suggest that seasonal variations have a more pronounced impact on oxidative status markers in dairy goats than nutritional factors.
