Comparative study to evaluate productive performance of Iraqi Turkey female Strains.

Abstract

The turkey females were randomly distributed on four groups, each group consisted of 12 birds depend on strain. The strains as follow, (T1): red turkey strain, (T2): bronze turkey strain, (T3): white turkey strain, (T4): black turkey strain. Each group constituted from 3 replicates and each replicate has 4 females. All birds housed under same environmental conditions. Feed and water were available (ad libitum) for all the period. Birds were fed on diet contains 20% crude protein and 2950 Kcal metabolic energy / kg through the experimental period. The flock was reared in a ground cages (pens) during the experiment period. Eggs were collected twice daily. Black turkey strain achieved the highest results, whereas the red strain recorded the lowest results in all traits measured in this study, also white turkey strain had superior on bronze turkey strain in all traits. Results revealed that strain had Significant effected on egg production rate, cumulative eggs number, egg weight, egg mass and feed conversion ratio, but, there was no significant effected for strain on feed intake.

Effect of Plumage Colour on The Productive and Physiological Performance of Two Lines of Turkey During Egg Production Period

“…Due to the variations in the plumage colour of different turkey varieties, the egg production period, egg weight, and egg quality results of previous studies vary (Anandh et al, 2012;Amao et al, 2016;Yenice et al, 2016;Pogodaev et al, 2020;Yahaya et al, 2021). In addition to the lack of information about its genetic potential for egg production and the expansion of projects aimed at producing meat rather than eggs, raising various local turkey lines, such as the Black, BBB, BR, and White turkeys, did not spread widely at the commercial or domestic levels in Iraq (Al-Janabi et al, 2019). To develop egg production with genetically improved traits and confirm the degree of adaptation of various turkey lines to environmental conditions, their egg production performance must be evaluated locally.…”
