| چکیده | ||
| هدف از انجام این مطالعه، بررسی اثر مخلوط پنج گیاه دارویی شامل سیر، اکالیپتوس، دارچین، آویشن، نعناع فلفلی و همچنین اسانس آنها بر تولید و ترکیب شیر و فراسنجههای خونی گاوهای هلشتاین در اواسط شیردهی بود. این آزمایش با 18 راس گاو شیری هلشتاین در قالب طرح کاملا تصادفی با سه تیمار شامل تیمار شاهد، تیمار مخلوط گیاهان دارویی (HPM:10 گرم در کیلوگرم ماده خشک کنسانتره) و تیمار مخلوط اسانس گیاهان دارویی(EOM:150 میلیگرم در کیلوگرم ماده خشک کنسانتره) به مدت 28 روز و با 6 رأس گاو در هر تیمار اجرا شد. تولید شیر روزانه در سه بار دوشش اندازهگیری شد. در روزهای پایانی آزمایش نمونهگیری از خون و مایع شکمبه انجام شد. تولید شیر و ترکیبات آن تحت تاثیر تیمارهای آزمایشی قرار گرفتند، بهطوری که استفاده از EOM در مقایسه با تیمار شاهد و HPM باعث افزایش تولید شیر (9/25 در مقابل 3/27 و 72/24 کیلوگرم در روز)، پروتئین (63/2 در مقابل 84/2 و 65/2 کیلوگرم در روز) و کل مواد جامد شیر (84/8 در مقابل 89/8 و 86/8 کیلوگرم در روز) گردید. هر دو ترکیب HPM و EOM غلظت کل اسیدهای چرب اشباع شیر را کاهش و غلظت اسیدهای چرب غیراشباع را افزایش دادند (05/0>P). غلظت آنزیم آسپارتات آمینوترانسفراز (AST) و تریگلیسرید پلاسما بعد از مصرف خوراک و پروتئین پلاسما قبل از مصرف خوراک تحت تأثیر تیمارهای آزمایشی قرار گرفتند (05/0>P). بهطور کلی استفاده از اسانسهای گیاهی با تاثیر بر الگوی تخمیر شکمبه، باعث بهبود تولید شیر درگاوهای شیری شده و میتواند سبب تغییر در ترکیبات شیر شود. | ||

| The aim of this study was to investigate the effect of mixing five medicinal herbs, including garlic, eucalyptus, cinnamon, thyme, peppermint, as well as essential oils on the production and composition of milk and blood parameters of Holstein dairy cows. This experiment was carried out with 18 dairy cow in a completely randomized design with three treatments, a medicinal herb mix (HPM: 10 g/kg dry matter concentrate) and a mixture of herbal essential oil (EOM: 150 mg/kg dry matter concentrate) for 28 days and 6 cowfor each treatment. Daily milk production was measured at three times. In the final days of the experiment, blood and rumen fluid sampling was performed. Results indicated that milk production and its compounds were affected by experimental treatments, so that the use of EOM increased milk production compaired to control and HPM (25.9 vs. 27.37 and 24.72 kg/day), Protein (2.63 vs. 2.84 and 2.65 kg/day) and total solids content (8.84 versus 8.89 and 8.86 kg/day). Both HPM and EOM combinations reduced the concentration of total saturated fatty acids and increased the concentration of unsaturated fatty acids (P<0.05). The concentration of aspartate aminotransferase (AST) enzymes and plasma triglyceride after food intake and total plasma protein concentration were measured before treatment (P<0.05).Generally, the use of herbal essential oils with an effect on the rumen fermentation pattern improves milk production in dairy cows and can change the composition of milk. | ||
