Background: Understanding the phenotypic and genetic parameter estimates of growth traits is important for an effective livestock genetic improvement programme. Objectives:In this study, we evaluated the phenotypic performances and estimated genetic parameters for birthweight (BWT), weaning weight (WWT), pre-weaning average daily gain (PADG), pre-weaning Kleiber ratio (PKR), pre-weaning growth efficiency (PGE) and pre-weaning relative growth rate (PRGR) of Fogera cattle in Ethiopia. Methods: Growth data collected from 2000 to 2018 in Andassa Livestock ResearchCenter were used for the study. General linear model of SAS 9.1 was used to estimate the least squares mean (LSM) ± standard error (SE) for phenotypic performances, and AI-REML of Wombat software combined with a series of five single-trait animal models to estimate phenotypic variance and its direct, maternal and residual components. Calf sex, calf birth season and calf birth year were the fixed effects considered.
The study was conducted to estimate the population size, herd structure, and breeding objectives of Fogera cattle in Ethiopia. It was carried out in 23 purposively selected kebeles in five districts of three zones bordering Lake Tana. Interviewed farmers were selected based on their livestock ownership. Primary information on the general production system and trends of Fogera cattle was collected from 527 farmers, and a population count included 479 respondents. To differentiate the pure Fogera cattle from the mixed and highland zebu breeds, color photographs of the three breeds were used by each enumerator. Kebele administrators and elders as well as district and zone officials assisted in the operation to identify the true type of Fogera cattle. MS-Excel (2010) and SPSS (version 20) were used to analyze population size and production systems, respectively. The average cattle holding per household was 7.03 ± 0.2 heads. Analysis of multiple responses revealed that the dominant reasons for keeping cattle in the herd were traction power (96.67%), milk (92.76%), and manure (83.95%). More than half of the respondents (64.65%) practiced culling both male and female animals from their herds. Interviewed farmers selected bulls for mating by coat color (56.84%), body conformation (55.08%), and body size (47.46%). They also indicated that they selected the Fogera breed (48.63%), highland zebu (18.16%), and mixed (17.38%) as bulls for mating with their cattle. Based on the respondents’ information, the population trend of the Fogera breed decreases (40%), increases (13%), is stable (6%), and is not known (41%). From the total population estimated, households own the relatively pure Fogera (41%), Fogera–zebu mix (35%), and highland zebu (24%). In this study, the total estimated number of breeding Fogera cattle was 55,646 ± 16,579 heads. It was concluded that the breed has declined and is dealing with genetic deterioration as the population size decreases due to the shift of grazing lands to crop production. As population estimation was performed by morphological features, further research supported by molecular study should be conducted.
Fogera cattle are one of the promising indigenous milk type local breed of Ethiopia. The objective of this paper was to evaluate the performance of Fogera breed under open nucleus breeding scheme. The work was done in two purposively selected districts (Gondar Zuria and Fogera) with community-based breed productivity improvement (CBBPI) as an approach. The collected data was analysed by GLM procedure of SAS for fixed factors estimation. Genetic parameters estimate was made by ASREML software for heritability and correlation. The overall milk yield of the nucleus herd was 2.26 ± 0.794 litter. From the total herd, best 10% and 25% of them give a respective milk yield of 3.31 and 2.87 litter; and some elite cows give an average of 5.45 ± 0.73 litter with a maximum yield of eight litters per day. The overall birth and weaning weight of nucleus herd calves was 21.30 ± 0.06 and 103.66 ± 0.59kg, respectively. Heritability for birth and weaning weight was 0.24 ± 0.09 and 0.18 ± 0.05, respectively. The phenotypic and genotypic correlation with their respective standard error between birth and weaning weight was 0.0613 ± 0.0075 and 0.0712 ± 0.0343, respectively. For CBBPI program, 17 pure Fogera bulls were distributed to the two districts. The birth and weaning weight of the village calves was 23.77 ± 0.21 and 85.89 ± 1.07, respectively. Through the program, above 1000 households were benefiting through the breeding program, health, forage development and grazing land management. To share the achievements of the results in CBBPI program, popularization through filed days and innovation platforms; and documentation of each step via publications, videos and pictures was done. From the result, it can be concluded that the strategy implemented for the breed conservation “open nucleus breeding scheme” had shown progressive results and improvement was recorded. To widen the result and improve the livelihood of the farmer, scaling up of the activity should better be planned with stakeholders.
