Two hundred day-old chicks of Lohmann Brown Broiler male (MPL) and female (FPL) parent lines were evaluated for production efficiency under the humid tropical environment. Chicks were reared on deep litter and fed chick breeder mash (0-8 weeks), grower mash (9-16 weeks), and broiler breeder mash (17-49 weeks). Water was supplied ad libitum. At point of lay, birds were floor-mated according to line in a ratio of 1 cock; 6 hens. Average body weights at 20 weeks were 2623.99 and 2189.35g for MPL and FPL, respectively. Female parent line chicken came into lay 4 days earlier than their MPL counterparts (142 vs 146 days). No statistical difference was observed in the total feed consumption per bird, with the values 8.89kg (MPL) and 8.62kg (FPL). There were no significant (P>0.05) differences between the two lines in percent hien-day egg production (PHD), fertility and hatchability of fertile eggs, values of which were respectively, 49, 12, 79.32 and 81.01 for the male line and 62.11, 80.89 and 82.28 for the female line during the last 26-49 weeks of age.

Ross 508 broiler breeder pullets (n = 400) were reared in floor pens in a light-tight facility with feed allocation based on breeder-recommended body weight targets. At 17 wk, 250 pullets within 15% of the mean weight were randomly assigned to individual cages in one of two environmentally controlled environments: 18°C (exp. 1, n = 125) or 28°C (exp. 2, n = 125). The pullets were photostimulated at 20 wk of age. At 2-wk intervals from 18 to 26 wk, successive groups of hens (n = 25 per environment) were switched from a 0.88% Ca grower diet to a 2.96% Ca breeder diet. Dietary treatment names were based on the time (in weeks) relative to photostimulation that the diet was changed from the grower to the breeder diet (PS – 2, PS, PS + 2, PS+4, and PS + 6, respectively). The hens were killed at 31 wk of age and one leg from each hen was taken for bone mineral analysis. The birds in both experiments maintained target body weights as recommended by the primary breeder; however, the hens in exp. 2 did not consume the allotted feed for the final 2 wk of the experiment. Dietary treatment did not affect feed consumption or body weight. Overall percent hen day production was not affected by dietary treatment in either experiment. In exp. 1, hens in the PS + 4 and PS + 6 treatments produced larger eggs and hens in the PS + 4 treatment produced eggs with greater shell weights. Shell weight as a percentage of egg weight was significantly lower from the PS + 6 hens than the other dietary treatment groups. The PS + 4 treatment resulted in the highest bone Ca as a percentage of ash weight, indicating that changing the diet 4 wk after photostimulation was the optimal time to increase bone Ca reserves in that environment. In exp. 2, the PS + 6 treatment had the highest egg weight whereas birds in the PS and PS + 2 treatment groups had the highest shell weights. Percent shell was the lowest in the PS + 6 and PS + 4 treatment groups overall, although it was only significantly different until 27.4 wk of age. Ca as a percentage of bone weight was lowest in the PS + 2 and PS + 6 treatment groups and Ca as a percentage of ash was lowest in the PS + 2 treatment group. Overall, the results suggest that improper timing of increasing dietary Ca either before or too long after photostimulation decreased eggshell quality and bone characteristics. Elevated environmental temperature appeared to exacerbate these effects; therefore, the change from a low-Ca grower to a high-Ca breeder diet must be made with greater precision in hot climates.

Two experiments were conducted to determine the effects of feeding fababean meal diets to laying hens. Body weight, feed consumption, egg production, egg weight, eggshell strength, and hatchability of eggs were the parameters recorded. In exp. 1, where two types of hens (Single Comb White Leghorn (SCWL) and broiler breeders) were maintained in floor pens, hens fed a diet containing fababean meal had lower final body weights, lower average egg weight, and lower percentage hatchability of eggs than those fed soybean meal. Feed utilization, egg production, and eggshell strength were not significantly affected by diets. In exp. 2, in which SCWL were maintained in cages, hens fed diets containing 29.75% fababean meal required more feed per dozen eggs, had lower egg weights and had lower percentage hatchability than hens fed diets containing 7.20% soybean meal. Body weights, feed per bird per day, egg production, and eggshell strength were not significantly affected by diets. Supplemental dietary lysine improved feed conversion and percent hatchability of eggs for hens fed the fababean diets. The combined number of early dead chicks and infertile eggs was higher for eggs from the hens fed fababean meal diets than those fed soybean meal diets.

A total of 43 (38 females and 5 males) adult native hilly chicken and 63 day-old chicks (44 hilly and 19 jungle fowl) were studied to understand their productive and reproductive performances under intensive management. The hen day egg production of hilly chicken during 11 months production period was 22.10% and average egg weight was 42.6 g. The adult body weights of female and male birds were 1701 g and 2690 g, respectively. The average daily feed consumption per bird was 101g during laying period. Hatchability of hilly chicken eggs was 91.35%. The day old chick weight of hilly chicken and jungle fowl was 29.4 g and 19.6 g, respectively (P?0.01). The body weight of hilly and jungle fowl were 503.8 g and 344.8 g, respectively, (P?0.05). There was no significant difference between hilly chicken and jungle fowl for feed consumption. Feed conversion ratios (FCR) were 2.80 and 4.4 for hilly chicken and jungle fowl, respectively (P?0.05). Mortality of adult birds during laying period was 16.4% and there was no chick mortality up to 8 weeks of age. Hilly chicken has shown potentiality to be used as meat type chicken. They require to reproduction freely under captivity to have a large number of breeding stocks for undertaking conservation and improvement programme.

A study was carried out to monitor the effect of feed manipulation on the growth and development of male and female line Hubbard broiler parent stock reared under tropical open sided poultry house without any form of cooling system or any temperature regulating mechanism. A total of 255 females and 105 males for the male line and 360 females and 150 males for the female line were used. The birds were fed a normal soya cake/groundnut cake and maize based broiler starter ration of 2900kcal/kg ME and 20% CP and a grower ration containing 2650kcal/kg ME with 16% CP as stipulated by the Hubbard rearing guide. The birds were fed ad libitum for the first 2 weeks and thereafter placed on restricted feeding in line with the standard rearing guideline provided by the Hubbard breeding company for optimum growth and development. It was observed that the body weights of the birds did not differ much from the standard body weight expected at 20 weeks even though they were reared in the normal tropical open sided poultry house without sophisticated modern facilities. This shows that feed manipulation can be used to achieve desired weight in broiler parent stock rearing

The Agassiz Research Centre keeps six pure lines of high-producing but non-commercial layers. Egg production, body weight, feed consumption and efficiency, and several characteristics of the eggs were measured to 60 wk of age and compared with those of four commercial white- and brown-egg hybrids. Egg production from 20 to 60 wk was highest for the four commercial hybrids, with no difference between them, and was 6 to 11% lower for the pure line white-egg layers, and 7 to 13% lower for the pure line brown-egg layers. The pure line and hybrid white-egg layers had similar body weights, but the pure line brown-egg layers weighed more than the commercial brown-egg hybrid. Feed efficiency was similar for the four hybrids and was generally better for the hybrids than the pure lines, based largely on higher egg production rather than increased feed consumption. The difference between industrial hybrids and the pure lines studied can be attributed to the selection that has been applied as well as to heterosis. Key words: Chicken, genetic resources, Agassiz layer lines

A total of 115 hilly chickens (92 female and 23 males) and 35 naked neck hilly Chickens (28 females and 7 males) were reared in open sided poultry house for 10 months period to compare their productive and reproductive performances. The mean body weights of adult female and male hilly birds and naked neck hilly birds were 2244, 2005 and 2664, 2576 g respectively. The age at first egg of both type of birds were 147 and 159 days respectively and hen-day egg production were 27±1.4 and 35±3.3 respectively. The average egg weight was 41±4 and 38±3.6 g respectively. Both type of bird per day average feed consumption were 97.61±11 and 102±22 g and mortality were 15.56±3.7 and 11.42±2.7 percent respectively. The average hatchability percentage performed by 14 broody hens reared on litter floor was 67.5±10 and 57±22 percent respectively. The average hatching egg weight and chick weight were 47.28±3, 41.48±1 and 31.4±3, 29.6±4 g respectively. The body weight of growing hilly bird and Naked Neck hilly bird after eleven weeks of age were 727.3±17.4 and 645±97.6g, respectively and Feed conversion ratios (FCR) were 3.39 and 3.34 respectively. It was concluded that Hilly chicken improved by body weight than previous year and both feathered and Naked Neck Hilly chicken given an indication of meat type native chicken and required to reproduce to have large stock for undertaking conservation and further improvement programme.Asian J.

The aim of the study was to identify quails which have different body weight for some production traits such as egg production, egg characteristics, daily feed consumption and feed conversion ratio (FCR). The selection was based on body weight in Japanese quail over two generations using 150 quails (120 female and 30 male). These groups consisted of Low Body Weight (LBW), High Body Weight (HBW) and control. Average body weights for females at the end of five weeks were 182.3±0.5, 159.5±0.34, and 141.7±0.55 for LBW, HBW and control groups respectively. There were significant differences between females and males in body weight across the generations. Significant differences were observed for total egg production and egg width for Group X Generation’s interactions. Also, statistically significant differences were found for egg quality parameters such as yolk index, yolk height, yolk diameter, albumin length, and albumin width among generations. As a result, body weight is a very important factor in selection studies and it also increases the efficiency of the selection program with other selection features.

The objective of the research was to evaluate to effect of feeding mengkudu on performances of broilers. The research design used was completely randomized design. One hundred broilers were distributed into five treatments. The treatments were different levels of mengkudu meal (0, 0.75%, 1.5%, 2.25 % and 3%). The observed measured were feed consumption, average body weight (gain) and feed conversion. Results showed that feeding mengkudu (Morinda Citrifolia L.)  no effect significant (P>0.05) on feed consumption, average body weight and feed conversion.  In conclusion, feeding mengkudu meal up to 3% (in diet) does not negatively affect feed consumption, average body weight, and feed conversion.
