Abstract

The aim of the present study was to find the effect of crushed wild Cumin (Bonium persicum) seeds as a feed additive in broiler diet during the starter phase on growth performance, nutrient digestibility and blood metabolites in broilers. For this purpose, 360 day old chicks were randomly divided into four groups. One group was the control while other experimental groups were supplemented with crushed wild Cumin (WC) seeds in the feed at the rate of 0.5 (WC1), 1 (WC2) and 1.5 g/kg (WC3). Results indicated that feed intake was significantly lower (p < .05) in WC1 and WC2 compared to WC3 and the control. Body weight was significantly (p < .05) higher in WC1 compared to the WC2. Feed conversion ratio was significantly (p < .05) lower in WC1 compared to the control. Percentage of crude fat, protein and calcium digestibility was significantly (p < .05) higher in WC1 compared to the control. Similarly, low density lipoprotein, total cholesterol and triglycerides concentration was significantly (p < .05) lower in WC1 and high density lipoprotein (HDL) cholesterol was significantly (p < .05) improved . On the overall basis, wild Cumin seeds at the rate of 0.5 g/kg were comparatively better to improve the growth, gut digestibility of the nutrients and blood cholesterol profile in broiler during the starter phase.

• HIGHLIGHTS

• Feed intake was lower in WC1

• Weight gain was higher in WC1

• Digestibility of nutrients was higher in WC1

• Blood cholesterol was lower in WC1

摘要

本研究的目的是发现压碎的野生小茴香种子（Bonium persicum）种子在开始阶段作为肉鸡饲料中的饲料添加剂对肉鸡生长性能，营养物质消化率和血液代谢产物的影响。为此，将360日龄的小鸡随机分为四组。一组作为对照组，而其他实验组在饲料中以0.5（WC1），1（WC2）和1.5 g / kg（WC3）的比例补充粉碎的野生孜然（WC）种子。结果表明， 与WC3和对照组相比，WC1和WC2中的采食量显着降低（p <.05）。 与WC2相比，WC1的体重显着更高（p <.05）。饲料转化率是显著（p 与对照组相比，WC1中的<.05）低。 与对照组相比，WC1中的粗脂肪，蛋白质和钙的消化率显着更高（p <.05）。同样，WC1中的低密度脂蛋白，总胆固醇和甘油三酸酯浓度显着降低（p  <.05），而高密度脂蛋白（HDL）胆固醇显着 提高（p <.05）。从总体上看，野生小茴香种子的添加量在0.5 g / kg的情况下相对更好，可以改善肉鸡在起步阶段的生长，肠道营养物质的消化率和血液胆固醇水平。

• 强调

• WC1中的采食量较低

• WC1的体重增加更高

• WC1中养分的消化率更高

• WC1中的血液胆固醇较低
