Feed cost represents about 70% of the total production costs of rabbit farms. There is little research on the usage of Berseem and Fenugreek seeds as substitutes for soybeans in rabbit diets. The current investigation was conducted to assess the influence of dietary inclusion of Fenugreek and/or Berseem seeds at varying levels as a substitute for soybean meal on reproductive performance, milk production, maternal behaviour, economic efficiency, mammary gland and ovarian histology, and relative expression of reproductive genes of New Zealand White rabbit does.

The source-sink relationship is critical for proper plant growth and development, particularly for vegetative axillary buds, whose activity shapes the branching pattern and ultimately the plant architecture. Once formed from axillary meristems, axillary buds remain dormant or become active to grow into new branches. This transition is notably driven by the regulation of the bud sink strength, which is reflected in the ability to unload, metabolize and store photoassimilates.

Article Synopsis
  • - The study focused on how hydrolyzed yeast (HY) supplementation affects growth, woody breast myopathy, and intestinal health in heat-stressed broiler chickens, using a 35-day experiment with various HY dosage groups.
  • The results showed that an 800 mg/kg HY diet reduced the feed conversion ratio and mortality rate during heat stress, along with lessening the incidence and severity of woody breast condition.
  • Additionally, HY supplementation improved gene expressions related to antioxidants and immunity, indicating potential benefits for maintaining gut health and overall performance in heat-stressed poultry.

In shrimp aquaculture, enhancing health and disease resistance is crucial for sustainable production. This study investigates the pioneering effects of astaxanthin-enriched microalgal powder from Haematococcus pluvialis (HP) on Pacific white shrimp (Litopenaeus vannamei), focusing on growth efficiency, body composition, immune and antioxidant responses, intestinal health, histopathology, gene expression, and resistance against Fusarium solani. Shrimp (initial weight 5.
