Sustainable agriculture approaches necessitate a concerted effort from researchers to establish paths that meet global population needs without compromising environmental resources. Goats are unique among ruminants because of their ability to adapt to some of the harshest environments around the world. Growth Hormone (GH) gene is a major regulator of muscle mass growth.

Article Synopsis
- Milk production is crucial in tropical and subtropical agriculture, accounting for about 47.32% of the world's output, and this study quantifies milk production and composition in warm climates.
- A meta-analysis of 42, 11, 15, and 16 papers for cows, buffalo, sheep, and goats, respectively, utilizing 2421 animal records, evaluates production levels and composition (fat and protein) adjusted for dry matter intake (DMI).
- Results indicate significant variations in production rates among different breeds, with foreign breeds producing the most milk (22.95 kg/day) compared to locals (7.13 kg/day), underlining a need for targeted improvements in dairy quality and production in hot climates.
The animal gastrointestinal tract contains a complex microbiome whose composition ultimately reflects the co-evolution of microorganisms with their animal host and their host's environment. This study aimed to gain insights into the adaptation of the microbiota of local Egyptian cattle to three different ecosystems (Upper Egypt, Middle Egypt, and Lower Egypt) distributed across 11 governorates (with an average of 12 animals per governorate) using amplicon sequencing. We analyzed the microbiota from 136 fecal samples of local Egyptian cattle through a 16S rRNA gene sequencing approach to better understand the fecal microbial diversity of this breed which developed under different ecosystems.

- The study examined camel hair fibers from Sudanese camels in Egypt to assess their quality and variability, focusing on how the sex of the animal impacted these characteristics.
- It found that camel sex did not significantly influence most physical traits of the fibers, although females had higher potassium content while males had higher glutamic acid levels.
- The research also revealed important correlations between fiber diameter and various traits, indicating potential ways to enhance the quality of camel hair fibers for use.
