试验始时(28 days)各组猪只分别称重,记录每一头猪的初重,以后分别在42、56日龄时称重,称重前空腹12h。每天记录采食量,观察记录发病、腹泻和死亡情况。统计其平均体重,平均日增重,平均日采食量,饲料转化率(耗料/增重),腹泻率(腹泻率=腹泻头日数?总试验头日数。每头仔猪一天腹泻1次或1次以上为1个腹泻头日数,每头仔猪参加一天试验为1个试验日数)。 1.5.2 血清中与免疫相关生化指标、激素指标测定 在试验中期(42日龄)和结束时(56日龄)称重后,各组分别采集3头体重接近的仔猪血液(共12头)外周血淋巴细胞增殖转化试验。另外各组再取接近平均体重的猪9头(每个重复组3头,共36头),于前腔静脉采血10ml左右,制备血清,测定血清中下列指标: (1)总蛋白、白蛋白、球蛋白含量(双缩脲法、色素结合法) (2)血清谷胱甘肽过氧化物酶(GSH-PX)活力(比色法) (3)丙二醛(MDA)水平(比色法) (4)IL-2、IL-6的含量 (放射免疫计数法) 42日龄时,试验C组血液中IL-2浓度最高,56日龄时试验C组血液中IL-2浓度显著高于对照组。血液中IL-6浓度在42、56日龄时都是D组最高,但与其它组相比差异不显著。 42日龄时,ConA诱导的T淋巴细胞增殖转化率在24小时和48小时时都是B组最高,D组最低,LPS诱导的B淋巴细胞增殖转化率与ConA诱导的T淋巴细胞增殖转化率变化一致。56日龄时,ConA诱导的T淋巴细胞增殖转化率在24小时和48小时时都是C、D组最高,LPS诱导的B淋巴细胞增殖转化率与ConA诱导的T淋巴细胞增殖转化率变化一致。 在仔猪日粮中采用3.5%solpro或5%solpro替代日粮中3%的血浆蛋白后,可显著提高56日龄仔猪血液中IL-2、IL-6、球蛋白浓度,并可显著提高56日龄仔猪血液T淋巴细胞和B淋巴细胞增殖转化率,表明采用3.5%solpro或5%solpro替代日粮中3%的血浆蛋白可显著提高仔猪免疫力。

AI回答:
At the beginning of the experiment (28 days), the weight of each group of pigs was measured, and the initial weight of each pig was recorded. Subsequently, the pigs were weighed at 42 and 56 days of age, with a fasting period of 12 hours before weighing. Daily feed intake was recorded, and the incidence of disease, diarrhea, and death was observed and recorded. The average weight, average daily weight gain, average daily feed intake, feed conversion rate (feed consumption/weight gain), and diarrhea rate (diarrhea rate=diarrhea head days/total experiment head days. Each pig having diarrhea once or more per day counts as one diarrheal head day; each pig participating in the experiment for one day counts as one experimental day) were calculated.

Serum biochemical and hormone indexes related to immunity were determined in the mid (42-day-old) and final (56-day-old) stages of the experiment, and 3 pigs with similar weights were selected from each group (12 in total) for peripheral blood lymphocyte proliferation transformation test. In addition, 9 pigs with average weight were taken from each group (3 pigs per replicate group, 36 in total), and blood samples of about 10 ml were collected from the anterior vena cava to prepare serum, and the following indexes were measured in the serum:

(1) Total protein, albumin, and globulin content (biuret method, dye-binding method)

(2) Serum glutathione peroxidase (GSH-PX) activity (colorimetric method)

(3) Malondialdehyde (MDA) level (colorimetric method)

(4) IL-2, IL-6 content (radioimmunoassay)

At 42 days of age, the IL-2 concentration in the blood of Group C was the highest, and at 56 days of age, the IL-2 concentration in the blood of Group C was significantly higher than that of the control group. The IL-6 concentration in the blood was the highest in Group D at both 42 and 56 days of age, but the difference was not significant compared to the other groups.

At 42 days of age, the T lymphocyte proliferation transformation rate induced by ConA was the highest in Group B at both 24 and 48 hours, and the lowest in Group D. The B lymphocyte proliferation transformation rate induced by LPS was consistent with the T lymphocyte proliferation transformation rate induced by ConA. At 56 days of age, the T lymphocyte proliferation transformation rate induced by ConA was the highest in Group C and D at both 24 and 48 hours, and the B lymphocyte proliferation transformation rate induced by LPS was consistent with the T lymphocyte proliferation transformation rate induced by ConA.

Replacing 3% plasma protein in the piglet diet with 3.5% or 5% solpro can significantly increase the IL-2, IL-6, and globulin concentrations in the blood of piglets at 56 days of age, and also significantly improve the T lymphocyte and B lymphocyte proliferation transformation rates in the blood of piglets at 56 days of age, indicating that replacing 3% plasma protein in the diet with 3.5% or 5% solpro can significantly improve piglet immunity.
