“…The biological name of goat is Capra hircus, more than 1153 goat breeds are listed in the Food and Agriculture Organization (FAO) of the United Nations (28). A goat population in Iraq estimated to be approximately 1.5 million heads, which again depends on cereal by-products and extensive pastures for feeding which is linked closely to the grazing patterns of other ruminants (27,32,38), as well the goat considered an important livestock in Iraq and has a significant function for the meat and milk products, especially under the systems of agriculture surviving in the country (8). Reproductive efficiency is always considered to be the most important factor ensuring increase in productivity for certain environmental conditions (36).…”

This study was conducted on 67 local doe goat, aged from 2-5 years old. The overall mean of TMY, DMY and lactation length of 1st and 2nd flocks were (130.541 ± 7.403 kg, 0.716 ± 0.033kg, and 182.432 ± 4.112 day) and (164.043 ± 8.788 kg, 0.832 ± 0.043 kg, 197.027 ± 2.650 day), respectively. The flock, age of doe, doe coat color, month of kidding and type of birth have significant effect on TMY and DMY, doe in 2nd flock production 33.502 and 0.116 kg milk/doe, respectively more than doe in 1st flock. Doe of five years old yielded (181.878 ± 10.171 kg /doe) and (0.892 ± 0.044 kg /doe/day) more milk than young doe. Doe kidding in Januarys were consistently produced high significantly (p≤0.001) more TMY (158.354 ± 7.076 kg /doe) and DMY (0.828 ± 0.033 kg /doe/day) in comparison with other groups. Doe with brown coat color produced significantly (p≤0.05) more TMY (165.205 ± 20.558 kg /doe) and DMY (0.835 ± 0.095 kg /doe/day) in comparison with other coat colors. Doe kidding twin’s kids were significantly (p≤0.05) yielded more TMY and DMY than single kids. The flock and age of doe significantly affected the lactation length, 2nd flock have higher length with 197.027 ± 2.650 day and higher lactation length recorded of doe with 5 years old with 200 ± 3.779 day. BLUP values for TMY of doe ranged from -130.65 to 224.77 kg/doe. The repeatability of DMY, fat%, protein% and lactose% in present study arrived 0.286, 0.319, 0.067 and 0.015 respectively. The MPPA value of TMY in this study ranged from 80.988 to 329.749. These results indicated the good genetic make-up of local goat for milk traits and the selection programs can play major role to increase production ability of local goat.

Objective: The study aimed to investigate the effects of castration on performance, carcass characteristics, and meat quality in sheep, as well as explore the expression of key genes related to metabolic pathways and muscle growth following castration. Methods: A meta-analysis approach was utilized to analyze data from multiple studies to compare the performance, carcass characteristics, and meat quality of castrated sheep (wethers) with intact rams. Additionally, protein–protein interaction (PPI) networks, differential gene expression (DEG) interactions, Gene Ontology (GO) terms, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways were examined to identify molecular mechanisms associated with fat metabolism and muscle development in sheep tails. Results: The analysis revealed that castrated sheep (wethers) exhibited improved average daily gain, increased tenderness, lower backfat thickness, and a tendency for greater loin muscle area compared to intact rams. This suggests that castration promotes faster growth and results in leaner carcasses with potentially higher muscle content. Furthermore, the identification of downregulated DEGs like ACLY, SLC27A2, and COL1A1 and upregulated DEGs such as HOXA9, PGM2L1, and ABAT provides insights into the molecular mechanisms underlying fat deposition and muscle development in sheep. Conclusions: The findings support the practice of castration in sheep production as it enhances growth performance, leads to leaner carcasses with higher muscle content, and improves meat tenderness. The identified changes in gene expression offer valuable insights for further research into understanding the impact of castration on muscle development and fat metabolism in sheep. This meta-analysis contributes to the knowledge of molecular mechanisms involved in fat deposition in sheep, opening avenues for future investigations in livestock fat metabolism research.
