摘要
从250头皖南花猪群中抽选出健康的6月龄后备母猪、发情母猪、妊娠母猪和哺乳母猪分别为4、4、4和5头,连续120小时观测皖南花母猪的行为规律。结果表明,4种母猪每天采食消化能分别为15.94、9.05、35.57和44.61兆焦耳;后备母猪平均每天饮水、排粪和排尿分别为4、2和1次,发情母猪分别为6、1和4次,妊娠母猪为4.8、2.8和5次以及哺乳母猪分别为6.3、2.3和2.6次。4种母猪全天站立活动时间分别占18.83、33.44、16.01和22.43％,其中白夭站立活动时间比夜晚长(P<0.01)。在每天的6～20时中,各类母猪每2小时的站立活动时间占全天的百分比(y)可用y=sum from 0 to 4(a_iX^i)来表达,其中X为6～20时中每2小时的上限值,a_i为参数。将发情、妊娠和哺乳母猪的参数分别与后备母猪相比,得到的对应参数比值分别为1.06～1.16、0.24～0.19和9.54～0.62。仔猪平均每次拱奶时间为76.5秒,母猪每次放乳时间33.3秒,白天拱奶时间比夜晚长(P<0.01)。白天和夜晚分别每隔1.26和1.45小时哺乳1次。
Four replacement gilts (RG) at the age of 6 months, 4 sows in estrus (ES),4 pregnant sows (PS) and suckling sows (SS) from the population of 250 Wannanhua sows have been selected to observe the behaviour patterns of Wannanhua sows in the day and night. The results showed that the digested energy intakes of RG, ES, PS and SS were 15.94, 9.05, 35.57 and 46.61 MJ/d, respectively. The frequencies of drinking, defection and urination for RG were 4, 2 and 1 times/d; for ES-6, 1 and 4 times/d; for PS-4.8, 2.8 and 5 times/d and for SS-6.3, 2.3 and 2.6 times/d. Average times of standing and walking of RG, ES, PS and SS a day were 18.83, 33.44, 16.01 and 22.43% during 24 hrs, respectively. The time of standing and walking in day-time was longer than that in night-time (P<0.01). The percentages (y) of the times of standing
and walking per 2 hrs within 24 hrs might be predicted by means of y = (aiXi), in
which X = the upper limit o'clock per 2 hrs from 6:00 to 20:00, and a = the parameter of corresponding Xi. The specific values of a; (i = from 0 to 4) of ES to RG's were 1.06~1.165 and the values of PS/RG and SS/RG were 0.24~0.19 and 0.54~0.62, respectively. The times rooting udder at a time averaged 76.5 seconds, which in day-time was longer than that in night-time (P<0.01). The times giving milk at a time averaged 33.3 seconds, which in day-and night-time didn't differ (P>0.05). The space times of nursing at a time in day-and night-time were 1.26 and 1.45 hrs, respectively.
