The effect of environmental factors on the lactation performance of crossbred dairy cattle in Ethiopia is discussed in this review.The efficiency of dairy farming systems is largely determined by the herd's lactation performance.The evaluation of lactation performance of dairy cattle is critical for the overall development of the dairy industry.Non-genetic (environmental) factors (parity, calving season, and calving year) significantly influenced common lactation performance indicators (daily milk yield (DMY), lactation milk yield (LMY), 305day milk yield (305DMY), and lactation length (LL)).Improving cow management (such as feeding, housing, disease control, and seasonal breeding) should be required to improve the lactation performance of crossbred dairy cattle.
What the full text shows
Shown in the lab- Cows calving in July-October had significantly higher lactation milk yield (LMY) than those calving in other periods. — 1482.05±68.90 liters vs 1376.39±74.50 (Nov-Feb) and 1364.23±84.32 (Mar-Jun) (Crossbred dairy cattle in Gondar)
- Daily milk yield (DMY) increases as parity increases from one to three. (Crossbred dairy cattle)
- Calving season significantly impacts daily milk yield (DMY) and lactation length (LL) in specific regions. (Alage & Ardaita TVETC and HARC)
- Calving season has no significant effect on 305-day milk yield (305DMY) in several locations. (Holleta, Debre Zeit, and ATVETC)
- Setup
- Review of multiple studies across various Ethiopian sites (e.g., Gondar, Holleta, Debre Zeit, Alage, Menkorer).
- How
- Literature review and synthesis of existing research papers on Ethiopian crossbred dairy cattle performance.
- Limitations
- Inconsistent results across different study sites regarding the significance of calving season. · Lack of specific quantitative data for most cited studies in the review table.
