The study was conducted in and around Shashamane city to assess commonly used feed resources, feed intake and productive performance of crossbred dairy cows during early lactation under farmers’ management. A total of 60 dairy farmers from urban and 60 from peri–urban (Kerara Filicha = 20, Kuyera = 20 and Arsi Negele = 20) were selected for the study. Structured questionnaire, secondary data sources and field observations were employed to generate data. A total of 48 animals from both small (16) and medium scale farms (32) in early lactation and parity from 2 to 6 were used for monitoring study for the period of 90 days. Fifteen major feed types used by dairy farms were identified in the area and categorized into five classes. Significant differences were observed in daily intakes of DM, crude protein and ME (P0.001) between production sub–systems and herd size groups. Higher daily energy requirement was satisfied in urban and medium scale farms than peri–urban and small scale farms. Daily milk yield was also significantly different (P0.05) between production sub–systems and herd size groups (P0.01). Therefore, from the current study it was concluded that the quality of available basal roughage feed is generally low and the productivity of animals on both production sub–systems and farm scale was below their expected genetic potential. Hence, large variation between production sub–systems and farm scale groups showed the opportunities for further improvement with strategic supplementation of energy and protein rich feeds.

The study was conducted in three districts of Ethiopian mid rift valley to evaluate germination date, blooming duration and number of bee visit of seven species of herbaceous bee forages. There was significant difference (P0.01) in germination date, blooming duration and bee visit among different bee forages in each site. Phacelia tanacetifolia, Bacium grandflorum, Trifolium pretense and Lenorus had the shortest germination date than other plant species at Adami Tulu Research station. Whereas, Lenorus, Bacium grandflorum and Trifolium pretense had short germination date at Bura Borema site and Lenorus is the only plant species with short germination date at Lephis site. There was significant difference (P0.01) in blooming duration between different species of plants tested in all sites. Aschynomene uniflorum and Sinapis alba had long blooming duration followed by Phacelia tanacetifolia at Adami Tulu Research station and Lephis, whereas, Echuin vulgare and Bacium grandflorum showed short blooming duration at this site. Similarly Aschynomene uniflorum and Sinapis alba showed long blooming duration at Bura Borema followed by Phacelia tanacetifolia and Lenorus. Bee visit was also significantly different (P0.01) between all plant species. Phacelia tanacetifolia was highly visited by honey bees in all sites, while Lenorus was the least visited forage in all sites followed by Sinapis alba. It is recommended that further demonstration and scale up is required at farmers’ apiary site particularly for Phacelia tanacetifolia, Bacium grandflorum and Aschynomene uniflorum.
