Local hen layers play a crucial role in egg production and the poultry industry. Optimizing their performance, egg quality, and overall health is of paramount importance.
This research aims to examine the effects of different feed forms on gut bacteria and subsequent effects on productivity, egg quality, and intestinal morphology in indigenous laying hens.
Forty-five hens aged 73 weeks were randomly distributed into three treatment groups, each with three replicates of 5 chickens in ground cages. The dietary treatments included a 100% mash diet (T1), 50% mash + 50% pellet diet (T2), and 100% pellet diet (T3).
Compared to the mash-fed group (T1), birds in the pellet and mixed-diet groups (T2 and T3) exhibited significant improvements ( ≤ 0.05) in productive performance and egg quality. Furthermore, there were significant reductions ( < 0.05) in intestinal weight, intestinal length, and gizzard weight, accompanied by significant increases ( < 0.05) in lactic acid bacteria and Spore-forming bacteria, along with a decrease in Aerobic bacteria and Colibacilli bacteria. Increases seen in beneficial bacteria were accompanied by increases in egg quality, especially when pellet form was utilized by the layer hens.
These findings support the advantages of using pellet diets to enhance productive performance and intestinal health and morphology in local hen layers.
本地蛋鸡在鸡蛋生产和家禽业中发挥着关键作用。优化它们的生产性能、蛋品质和整体健康至关重要。
本研究旨在考察不同饲料形式对本地蛋鸡肠道细菌的影响以及对生产性能、蛋品质和肠道形态的后续影响。
将45只73周龄的母鸡随机分为三个处理组，每组5只鸡，在地面笼中设三个重复。日粮处理包括100%粉料日粮（T1）、50%粉料+50%颗粒料日粮（T2）和100%颗粒料日粮（T3）。
与粉料饲喂组（T1）相比，颗粒料组和混合日粮组（T2和T3）的鸡在生产性能和蛋品质方面有显著改善（P≤0.05）。此外，肠道重量、肠道长度和肌胃重量显著降低（P<0.05），同时乳酸菌和芽孢杆菌显著增加（P<0.05），需氧菌和大肠杆菌减少。有益菌的增加伴随着蛋品质的提高，尤其是当蛋鸡采用颗粒料形式时。
这些发现支持了使用颗粒料日粮提高本地蛋鸡生产性能、肠道健康和形态的优势。
