“…The results of the hen's body weight at the first egg in SSxYEC were lower than the findings of Khan et al (2006), who reported weight at the first egg in Fayoumi chicken with an average body weight of 1253.53 ± 16.43 g and first egg weighing 45.79 g under intensive management. Meanwhile, Chineke (2001) reported that the association between body weight and selected egg traits (egg length, egg breadth, egg index, egg weight, albumen weight, yolk weight, shell weight, shell thickness, and hen-day production) was nonlinear. He recommended maintenance of an optimum body weight range of 1.72 to 1.80 kg, following the report of Akanni et al (2008) on a black Nera pullet, which attained sexual maturity at 188 days and a body weight of 1421.59 g/bird.…”

Yoruba Ecotype Chicken (YEC) is characterized by hardiness, and better adaptation to prevailing tropical environment. However, its poor egg production has hindered its utilization for commercial production. Crossbreeding is a major tool used in improving desired traits in animals. The objective of the study was to evaluate egg production and quality characteristics in YEC and its crosses with Goliath (GG) and Sussex (SS). The study investigated egg production and egg quality characteristics using 120 sixteen-week-old YEC and its crosses. The findings of the study showed that egg parameters were significantly higher (p<0.05) and maturity occurred earlier (154 days) in YECxSS than in YECxYEC (146 days) and other YEC crosses. The study concluded that cross breeding improved egg production of YEC. Crossbred YEC x SS is therefore recommended for egg production in Nigeria.

“…The higher egg weight and egg length measured in the F 2 crosses showed the impact of improved genetics on the egg quality. This higher egg quality could be due to higher body weight of F 2 progenies compared to the indigenous and F 1 progenies, since increased body weight may connote higher qualitative egg characteristics like the egg weight (Anyaegbu et al, 2016;Chineke, 2001). The result of our study is also similar with the study of Nwachukwu and Ogbu (2015), who reported that reciprocal backcrossed eggs were better in respect of shell weight, yolk weight, yolk index, albumen weight and haugh units than their F 1 bird eggs.…”

This study evaluates the growth performance, body linear parameters and egg quality of Yoruba ecotype chicken and their F1 and F2 crosses using Lohmann brown cocks under a low-input management system. Ten Lohmann brown cocks were mated with thirty indigenous hens to obtain the F1 progenies. Ten Lohmann cocks were also mated back to thirty F1 hens to obtain the F2 progenies. Also, ten indigenous male cocks were mated with 30 indigenous female hens as a basis for comparison. Mating was done at 1:3 in all the groups. Incubation and hatching were naturally done and properly monitored. After hatching, the hens and the chicks were intensively managed for 8 weeks in wooden cages, after which the chicks were transferred to battery cages, where they were raised till maturity. Initial weight at hatching, body weight at 24 weeks, average daily feed intake, body weight at initial egg laying and first egg weight were recorded appropriately, while the body linear parameters (shank length, comb length, keel length, back length, beak length, neck length and drumstick) were measured using standard procedures. Some selected egg quality parameters included egg weight, egg length, egg breadth, shell weight and albumen weight. Weight at hatching, body weight at 24 weeks, average daily feed intake, body weight at initial egg laying and first egg weight were significantly (P < 0.05) higher in F2 birds than in F1 birds, while F1 birds had higher values compared to the indigenous birds. The F2 birds also had significantly (P < 0.05) higher egg weight, egg length, egg breadth, shell weight, shell thickness, albumen height, albumen weight, yolk length and yolk weight than F1 birds. This study showed that the F1 and F2 progenies performed better in growth, body linear parameters and the egg quality parameters compared to the indigenous chicken. It can, therefore, be concluded that crossbreeding of indigenous chicken with Lohmann breed is beneficial for improving their growth performance and egg quality parameters, thereby enhancing their productivity.

“…More so, inclusion of SCR resulted in more economic egg production, and consequently profitability [8]. The egg weight observed is lower than 59.50-64.50 g for European commercial strain and 63 g Olympic black layers [13] and 43.67-58.33 g [9]. However, egg weight appeared to be in favour of diets containing SCR.…”

8 weeks feeding trial was undertaken to evaluate soybean cheese residue (SCR) with 29 weeks old layers. SCR was incorporated at 0, 5, 10, 15 and 20 % in diets T1, T2, T3, T4, and T5 respectively. Ninety (90) twenty-nine week old birds were used for the experiment. The birds were allocated to the five diets in a Completely Randomized Design (CRD). Each treatment had eighteen (18) birds such that each replicate had six (6) birds. There were no observed significant differences (p>0.05) in final weight and weight gain. Hen day production, daily feed intake, feed conversion ratio, feed cost/kg, feed cost/egg crate and profit indicated significant differences (p>0.05). HDP ranged from 39.73 % to 49.64 %. Feed intake was 101.25 g to 117.20 g. Feed conversion ratio showed value range of 3.83 to 4.19. Feed cost/kg had a value range of N90.00 to N170.00. Feed cost/egg crate showed value range of N702.89 to N834.28. Value for profit ranged from N74.43 to N447.26. Supplementation of SCR influenced the performance and profitability of the layers. Egg quality characteristics were measured at intervals and average computed for each diet. Egg weight, egg length and egg width were significantly affected (P<0.05) in favour of SCR diets. But shell weight and shell thickness were similar for all the diets. Egg content weight and yolk weight were significantly (P<0.05) affected, while albumen height, yolk diameter, yolk height and Haugh unit were similar. The values observed for egg weight, egg length, egg width, egg shell weight, shell thickness 53.47-54.88g, 3.65-3.87 cm, 2.68-2.71 cm, 7.43-7.61 g and 0.54-0.59 mm respectively. Egg content weight, albumen Height, yolk diameter, yolk weight and Haugh unit ranged from 45.87 49.09 g, 5.21-5.81cm, 2.49-2.81 cm, 1.27-1.31 cm, 13.78-18.10 g and 73.86-78.10 respectively. The addition of SCR increased profit because it reduced cost of production besides promoting better productivity. Furthermore, SCR inclusion in the diet of layers did not affect egg quality adversely. The inclusion of SCR in layer diet is recommended even up to 20%.
