| dc.description.abstract | The study was conducted to evaluate performances of crossbred cows and characterization of dairy farm enterprises managed by youth groups in selected areas of South Gondar zone, Amhara region, Ethiopia. All (20) dairy farm enterprises that are managed by youth groups were selected by the available sampling method and interviewed using structure and semi-structured questionnaire to obtain data about the dairy farm enterprises farming practices. A total of 204 lactating cows were selected for measurement and monitoring purposes. The type of collected data was both quantitative and qualitative data’s and the types of data collection methods were primary and secondary data. The independent variables considered included location, stage of lactation, blood level, and parity while performances (daily milk yield (DMY), lactation milk yield (LMY), lactation length (LL), calving interval (CI), days open (DO), and number of services per conceptions (NSC), linear body conformations (stature (STA), chest width (CW), body depth (BD), body length (BL), rump length (RL), heart girth (HG), neck length (NL), and neck circumferences (NC)), linear udder conformation trait (rump width (RW), udder depth (UD), udder width (UW), udder circumferences (UC), rear udder height (RUH), teat length (TL) were the dependent variables. Survey data were analyzed by SPSS software while monitoring data were analyzed using the General Linear Models procedure (GLM) of the Statistical Analysis System (SAS, 2004). The survey results revealed that the majority of respondents (70%) were males with diverse educational levels. The main feed sources of dairy cows were agro-industrial by-products and ration feeds. The watering frequency of most farms (45%) was free access and majority of farm owners (55%) had communal sheds. The monitoring results showed that the overall mean ±SD of DMY, LMY, LL, CI, DO, and NSC were 7.92±2.4 litter, 2078.91±850.9 litter, 8.56±1.3month, 12.89±1.64 month, 3.54±0.9 months, and 1.7±0.6, respectively. Whereas, the overall STA,CW,BD,BL,RL,HG,NL,NC,RW, RUH,UD,UW,UC and TL were 127.81±5.4 cm, 23.1±3.1cm, 99.2±4cm, 120.45±4.6cm, 32.2±3.9cm, 168.32±5.1cm, 56.7±3.2 cm, | en_US |
