This study aimed to determine the effect of sodium butyrate (SB) on reproductive tract development and histomorphometric analysis of testes in neonatal kids, as well as on their growth, antioxidant status and some blood metabolites. Thirty-six neonatal Zaraibi kids were divided immediately after 4-5 days from birth into three equal groups (12 kids/ each). The first group (G1) received milk replacer (MR) at a rate of 10% of the body weight until the weaning. The second group (G2) received 9.7% MR supplemented with 0.3% SB. The third group (G3) received whole milk and served as a control. The results revealed that there was significant (p < .001) increase in total and daily gain between the G2 and G1 groups, whereas there was no significant change between G2 and G3 groups. Body condition score was slightly increased (p > .05) in G2 compared with G1. Serum total protein and cholesterol levels were significantly decreased in treated groups compared with the G3 group, on reverse globulin and glucose levels had no significant changes. Also, T3 and testosterone concentrations were significantly (p < .0001 & p < .05) higher in G3 and G2 than G1. Antioxidant status was enhanced through decreasing the oxidative marker and increasing antioxidant enzymes activity in G2. Testis parameters in G3 and G2 kids had the highest values, compared with G1. G1 and G2 had thin basement membrane of seminiferous tubules with few Leydig cells and pyknotic germinal epithelium, while G3 showed thick basement membrane, mild wide interstitial spaces with many Leydig cells. The tubular diameter was also significantly larger in the G3 and G2. It could be concluded that MR supplemented with SB can be used as alternative whole milk in suckling goat kids for maintaining reproductive tract and kids' performance through improving the antioxidant status.

在补充丁酸钠的牛奶替代品上抚养的新生儿Zaraibi儿童的生殖道发育和睾丸组织形态计量分析。

这项研究旨在确定丁酸钠对新生儿睾丸生殖道发育和睾丸组织形态分析的影响,以及对他们的生长,抗氧化剂状态和某些血液代谢产物的影响。从出生后4-5天起,将36名新生儿Zaraibi孩子立即分为三个相等的组(每组12个孩子)。第一组(G1)接受断奶前体重的10%的代乳品(MR)。第二组(G2)接受9.7%MR补充0.3%SB。第三组(G3)接受全脂牛奶作为对照。结果显示,G2组和G1组之间的总和每日收益显着增加(p <.001),而G2和G3组之间没有显着变化。身体状况评分略有提高(p>。05)在G2中与G1进行比较。与G3组相比,治疗组的血清总蛋白和胆固醇水平显着降低,而反向球蛋白和葡萄糖水平无明显变化。此外,G3和G2中的T3和睾丸激素浓度显着高于(P <.0001和P <.05)。通过降低G2中的氧化标记和增加抗氧化酶的活性来增强抗氧化状态。与G1相比,G3和G2儿童的睾丸参数值最高。G1和G2的生精小管基膜薄,Leydig细胞少,粘滞性生发上皮少,而G3的基膜厚,间质间隙宽,Leydig细胞很多。G3和G2中的管径也明显更大。
