“…These results show that feed intake was not significantly depressed in the inbred groups and this could be related to the equivalent growth performance observed between the G 1 population and their inbred progenies. The results also show that feed intake may not be liable to inbreeding depression in accord with Wiener [18] and Udeh and Omeje [7].…”

“…No significant differences in body weight were observed for other groups across the age periods. The observed similarity in growth performance between G 1 and G 2 birds is supported by Udeh and Omeje [7] who reported equivalent body weight and body weight gain at 4, 12, and 20 wk of age, respectively in inbred exotic and local chickens. These results support our earlier submission that the G 1 birds bred true and this indicates high additive genetic effect on growth performance in the NIC.…”

“…Body weight gain and feed:gain ratio differed significantly (P˂ 0.05) between G 1 and G 2 generations across the entire age periods (wk 4 to 20, respectively) and were depressed in the G 2 generation with a range of 13.72 to 24.97% for body weight gain and 19.93 to 23.97% for feed:gain ratio. The depressed body weight at hatch in inbred group could result from reduced egg size in this group as was alluded to by Udeh and Omeje [7]. The response obtained at wk 12 could relate to a delay in the initiation of the effect of genes responsible for transition from juvenile to adult body weight.…”

“…Carefully planned and coordinated inbreeding (mating of individuals related by descent) or within line/family breeding (involves inbreeding) provides ready means of achieving this. Inbred lines are known to be homozygous for favourable genes at most loci (depending on the level of inbreeding) [5] and to manifest positive heterosis when genetically divergent lines from different genetic backgrounds are intercrossed [5,6,7]. Again, inbred lines allow the unlimited production of animals of the same genotype for repeated genetic evaluation and phenotypic characterization [5].…”

The objectives of the study were to evaluate and compare the growth performance (body weight, BWT, and body weight gain, BWG), feed intake (FI) and feed:gain (F:G) of G 1 and G 2 generations of inbred Nigerian indigenous chickens (NIC). A total of 500 chicks (250/generation) were used for the study. The G 1 birds were produced from sire families established from a base population of random breeding NIC whereas the G 2 birds were progenies of half and full sib matings involving the G 1 population. Result showed significant (P˂ 0.05) sire and line effects for BWT in G 1 and G 2 generations, respectively. Feed intake did not vary much between sire groups (G 1 generation) but varied without a definite trend between sire lines in G 2 generation. Differences between sire group and their progenies were non-significant in most of the parameters except for

“…Growth rate at different ages are useful selection criteria and important tool in most of the breeding programs in animal production; i.e. increase live body weight, weight gain, feed intake and mortality during early period of life (Hassan, 2011;Udeh and Omeje, 2011;Hussen et al, 2016;Fadhil and Hassan, 2018).…”

The research work has been constructed at Sulaimani Research Station-Director of Agricultural Research to study the effect of three lines of local chickens: Pure black (line 1), Black with brown Neck (line 2), White (line 3) and Isa Brown (line 4) at four periods (19-32, 33-43, 44-60 and 61-75 weeks) on egg production traits. The age at first day of egg production, first week of production, sexual maturity, when reach to 50% and peak egg production and long duration of peak egg production were recorded. In addition to estimate the egg/hen/all periods, egg/hen/week, egg/ hen/ all period% and hen day egg production%. No significant difference between lines on age at first day of egg production, first week of production, sexual maturity and reach to peak production. Line 2 significantly (p<0.05) reach to 50% before other lines about 8-21 weeks. Moreover, line 3 significantly (p<0.05) has the shorter duration of egg production compared with other lines. Hen day egg production% at age at sexual maturity, at 50% production and throughout long duration of production did not significantly differed between lines. Peak production% of line 2 was significantly (p<0.05) higher than other lines. Egg weight was significantly (p<0.05) higher in line 4 compared with lines 1,2 and 3, but did not significantly differed with line 3 in egg/ hen/ all periods and egg/ hen/ week. As for percentage of egg production, line 2 was significantly (p<0.05) higher in percentages (33.20 and 34.30%) for egg/ hen/ periods% and Hen Day Production%, respectively. As the age increased the egg weight was increased, while egg/ hen/ period, egg/ hen/ week and percentage of egg production were significantly (p<0.05) higher at period 3.
