Nigerian indigenous chicken (NIC) from three agro-ecological zones (Rain Forest, RF; Derived Savanna, DS; and Guinea Savanna, GS) were evaluated for age at first egg, egg production and egg weight, percent hen-day egg production and percent laying mortality. Data for this work were collected over a period of 72 weeks. A total of 579 eggs from DS and RF zones and 505 growers from DS, GS and RF were evaluated. Data were compiled by Dbase IV and analysed using the General Linear Model (GLM) procedure of Statistical Analysis System (SAS). Agro-ecological zones, age and sex were the fixed effects in the model. Means for each variable effect were compared using the Least-Square Analysis of Variance and Duncan option of SAS. For all the traits evaluated, there was no significant difference between the chickens from the three ecological zones. Hence, the Nigerian indigenous chickens from these zones cannot be said to belong to different genetic groups.

Information from 400 randomly selected female farmers was obtained during the year 1997 to assess the production performance of backyard chicken in Charsadda district, North West Frontier Province (NWFP), Pakistan. Only 16.3% of the farmers were regularly vaccinating their flocks. The majority of the farmers initiated immunization only at the time of disease onset (29.7%) followed by those (28.5%) who did not vaccinate. A high proportion (53.3%) provided no housing, 29.8% provide night shelters and 17% had no housing. Average flock size was 22.0 birds, comprising 8.86 chicks, 2.03 pullets and 11.1 layers. The local Desi chicken dominated the flocks (10.2 birds) followed by Fayumi (6.76), Rhode Island Red (4.20) with White Leghorn least popular (0.83 ). Average mortality in a flock was 23.6%. Mortality was higher in layers (28.1%) than in pullets (18.7%) and chicks (24.2%). Significantly higher losses were found in White Leghorn (35.6%) than in Desi chicken (17.5%). Similarly, higher mortality was found in chicken without housing facilities (26.7%) than in those with access to houses (21.6%). Regular vaccination was associated with higher productivity than vaccination at the onset of disease or no vaccination. Average annual egg production was 76.4 for Desi, 109 for Fayumi, 169 for Rhode Island and 153 for White Leghorn. Mean hatchability was 61.2% with an annual frequency of 4.6 settings and 15.1 eggs set per broody hen. Farmer preference for the "local" Desi chicken reflected their greater capacity to survive and adapt to scavenging management systems. Fayumi and Rhode Island chickens appear to merit further studies as breeds that could improve the productivity of scavenging systems, as they had higher egg production and only slightly higher mortality than Desi chicken.

National forest inventory (NFI) is an efficient way to monitor forest resources, including increment, mortality, and harvest rate. It provides accurate statistical information about land use data, land use change and biomass stock change and enables to tie the specific increment, mortality and harvest data to defined land use category, dominant tree species, site types etc. Recently there have been introduced changes in land use calculation method using NFI data in Latvia. New calculation method takes into account present land use data and land use data from two previous cycles considerably reducing uncertainty of the estimates and takes into account possible land management practices which may alter the land use category in long-term, also usage of auxiliary data has been introduced to increase accuracy of determination of final land-use category. Changes in land use calculation method directly affects distribution of data on increment, morality and harvests between land use categories. The aim of the study is to determine increment, mortality and harvest rate in Latvia between the first and third NFI cycle (2004-2018) using updated land use data and to compare obtained result with data from the most recent greenhouse gas (GHG) inventory report.
