چکیده مقاله :

The association of birth type (single vs. double) and pregnancy type (single vs. double) with lactation performance and lactation curve was investigated in Holstein cows in Iran. Data of 243298 lactations on 138021 cows in 261 herds collected during January 2000 to December 2012 were used. The average twinning rate was 3.64% and ranged from 1.44% (primiparous) to 5.41% (multiparous). Factors associated with twining were calving season, calving year, herd, and parity. The rate of twinning increased from 2.49% in 2000 to 3.42% in 2012. The probability of twinning was higher in multiparous cows than that in primiparous [Odds ratio (OR) (95% confidence interval (CI))= 3.64 (3.44-3.84) for multiparous vs. primiparous cows]. The probability of twin pregnancy was higher in cows previously delivering twins than that in those delivering singles [OR (95% CI)= 3.17 (3.02-3.34) for cows delivering twins vs. cows delivering singles]. The lactation curve for cows delivering singles in previous gestation and pregnant with twins in subsequent gestation tended to be lower and flatter. The incidence of twin pregnancy was increased as the cow reached its peak yield earlier, and produced more milk at peak lactation. Primiparous cows delivering singletons in their previous gestation and having twins in their subsequent gestation produced more 100-d, 200-d and 305-d milk than those pregnant with singletons. Multiparous cows that delivered singleton in previous gestation and were pregnant with twin in the subsequent gestation, produced more milk during the first 100-d and 200-d of lactation than those pregnant with singles.

چکیده انگلیسی:

رابطه­ نوع زایش (تک­قلو یا دوقلو) و نوع آبستنی (تک­قلو یا دوقلو) با عملکرد شیردهی و منحنی شیردهی در گاوهای هلشتاین ایران بررسی شد. از داده­های 243298 دوره شیردهی 138021 گاو در 261 گله که در سال­های 1378 تا 1391 گردآوری شده بود، استفاده شد. میانگین دوقلوزایی 64/3 درصد و بین 44/1 (گاوهای شکم نخست) تا 41/5 درصد (گاوهای شکم دو و بالاتر از دو) متفاوت بود. فصل زایش، سال زایش، گله و شکم زایش بر دوقلوزایی تأثیر داشتند (05/0‌P<). درصد دوقلوزایی از 49/2 در سال 1378 تا 42/3 در سال 1391 افزایش نشان داد. درصد دوقلوزایی در گاوهای چند‌شکم زایش در مقایسه با گاوهای شکم اول بالاتر بود (05/0‌P<). احتمال آبستنیِ دوقلو در گاوهایی که در زایش قبلی دوقلو داشتند، در مقایسه با آنهایی که در زایش قبلی تک‌قلو داشتند، بیشتر بود (05/0‌P<). منحنی شیردهی در گاوهایی که در زایش قبل تک­قلو داشتند و دوقلو آبستن بودند، پایین­تر و صاف­تر بود. احتمال آبستنیِ دوقلو در گاوهایی که زودتر به اوج تولید می­رسیدند و تولید بیشتری در اوج داشتند، بیشتر بود. تولید شیر 100، 200 و 305 روز، در گاوهای شکم اول که در زایش قبل تک­قلو داشتند و دوقلو آبستن بودند، بیشتر بود. گاوهای چند‌شکم که در زایش قبل تک­قلو داشتند و دوقلو آبستن بودند، تولید شیر 100 و 200 روز بیشتری داشتند.
