Effects of environment and genotype for the expression of weight gain of Fayoumi and Sonali chicks

Environmental as well as genotypic effect on weight gain is a normal phenomenon. The aim of the present study was to determine the environment and breed effect on weight gain. One observational cross-sectional study was done on the Fayoumi and Sonali chicks at Chittagong and Noakhali district from October 2005 to July 2006. A total of 48 farmers (24 from each Upazila) were selected randomly, who rear chicks under scavenging condition as well as had broody hens. Twelve eggs of each breed were supplied to each farmer. The chicks were hatched out by the farmers managed broody hens. Then the chicks were reared under scavenging system. The weight-gain of Fayoumi chicks after 8 weeks was higher (226.0 gm) than Sonali (170.7 gm) and it differed significantly (χ2 = 7.71, df = 1, p < 0.01). The Fayoumi chicks of Chittagong site gained higher weight (285.4 gm) than that of Noakhali (171.1 gm). In case of Sonali chicks, the weight gain of day old to eight weeks aged showed the similar performance in both Districts. Chicks of both breeds gained better weight in Chittagong than Noakhali significantly (Fayoumi: χ2 = 28.6, df = 1, p < 0.001; Sonali: χ2 = 10.01, df = 1, p < 0.01). Weight gain and environmental adaptation of Fayoumi chicks were better than Sonali.Key words: Environment; Fayoumi; genotype; Sonali; weight gain.DOI: http://dx.doi.org/10.3329/ijns.v1i1.8611 International Journal of Natural Sciences (2011), 1(1):22-24

Morphometric analysis of indigenous, exotic and crossbred chickens (<i>gallus domesticus</i> L.) In Rajshahi, Bangladesh

Context: The quantification of morphometric variations has been regarded as peripheral to the mechanistic study of development of a species. This is now changing because the rapidly advancing knowledge of development in post-genomic biology is creating a need for more refined measurements of the morphometric changes produced by genetic perturbations or treatments. Objective: To estimate the age at marketable size and body morphometric parameters of indigenous, exotic and crossbred chicken to use such parameters as discriminate variables and to investigate the relationships among the variables of the chicken breeds under study. Materials and Methods: Six chicken breeds namely an indigenous (non descriptive, Deshi), four exotics as Broiler, Cockerel, Fayoumi and RIR, and a crossbred called Sonali (RIR?× Fayoumi?), were used for the study. Results: Age and nine morphometric parameters viz., gross weight (GW), blood weight (BW), feather weight (FW), skin weight (SW), body weight after skinning (BWS), visceral weight (VW), offal weight (OW), net edible weight (NEW) and edible ratio (ER), were determined from a total of 30 adult chickens (6 breeds _ 5 replicates each). All the parameters except FW showed significant differences among the breeds (P<0.01). RIR showed the highest values for all parameters except ER, which was the highest in Cockerel (1.77±0.23) and the lowest in RIR (1.47±0.01). Association between GW and NEW was statistically significant in Indigenous (P<0.001), Sonali (P<0.01) and all exotics except Broiler (P<0.001). Conclusion: Present results indicate that Cockerel, Fayoumi, Indigenous and Sonali chickens are advantageous genotypes as they had higher ER values compared to Broiler and RIR breeds.

Gross protein value units in the standardisation of rations for Fayoumi chicks.

Synopsis For the standardisation of rations for Fayoumi chicks, gross protein value unit (G.P.V.U.) was introduced; this was taken to mean the amount of supplementary protein that would stimulate as much growth as 3 per cent casein protein having gross protein value of 100. Three total protein levels were tested in diets containing the same productive energy levels (1800kcal./kg.) and G.P.V.U.’s (30 per kg. of food). Since no significant differences in chick growth were recorded up to 8 weeks of age it was concluded that it is practical to adjust the energy :protein ratio between productive calories and G.P.V.U.’s per kg. of food irrespective of the total protein in the diets of growing Fayoumi chicks.

Cytological and Biochemical Studies on the Blood Constituents of Normal and Spirochete-Infected Chickens

Spirochetosis is indigenous in Egypt, causing considerable losses, especially in young susceptible chickens. Evidence is lacking on blood changes during infection. This paper describes changes in the cellular portion of the Fayoumi chickens infected experimentally. Also reported are additional studies on the comparative biochemistry of some blood constituents of normal and spirocheteinfected Fayoumi chickens.

Observations Made during a Natural Outbreak of Aegyptianellosis in Chickens

Aegyptianellosis in Sudanese fowls was first reported by Balfour (2). Carpano (3), who named the causative organism Aegyptianella pullorum and considered it a piroplasm, found the infection in both chickens and geese in Egypt. The disease in Egypt has been shown to prevail mainly during the period May to July and to be far less common than spirochetosis (1). This note reports on clinical and hematological observations made during a natural outbreak of Aegyptianella pulorum infection in native Fayoumi chickens. The significance of the hematological findings as a possible means of differential diagnosis of this infection from spirochaetosis is pointed out. In the early summer of 1964, a group of 31 8-10-week-old Fayoumi chickens of both sexes experienced a disease condition manifested at first by droopiness, ruffled appearance, disinclination to move, staggering gait, and diarrhea. These signs persisted for about 6 days and were followed by marked weakness, paleyellowish discoloration of the face, comb, wattle, visible mucous membranes, and, in some birds, paralysis of the legs. At this stage, 3 birds died and the other showed slow recovery. This group of chickens was among birds kept on hand for experimental purposes. They had been vaccinated as day-old chicks against Newcastle disease with the F strain and fed on a commercial ration. They were first reared in a battery in an isolated room until 6-8 weeks old and then transferred to a room with straw litter, where they were kept in confinement. The clinical signs and the season of the year suggested the possibility of a spirochete infection. Accordingly, blood films were prepared from the wing vein of the individual birds of this group

A Comparison of Sexual Maturity Age and Egg Weight Between Standard Breeds and Fayoumi Chickens in Subtropics

INTRODUCTIONONE of the main suggestions to solve the problem of the shortage of both eggs and meat in Egypt is to import and adapt the high yielding foreign breeds of poultry.The author follows up his study of three commercial strains imported from Holland and the native strain known as Fayoumi. Amer (1956) compared the foreign breeds and Fayoumi with respect to fertility, hatchability, body weight and body measurements. Later on, Amer (1964), made a comparison between the previous breeds and the local strain with respect to annual egg production and mode of laying. This paper deals with the study of age at sexual maturity, body weight at sexual maturity and egg size in the standard breeds and Fayoumi. REVIEW OF LITERATURESexual Maturity: Byerly and Knox (1946) reported that pullets of later hatches laid their first egg at older ages than those of earlier hatches. They added that…

Embryonic Mortality and Malpositions in Fayoumi Chicken

DESPITE the precautions undertaken to secure better hatchability, some eggs fail to hatch. Such eggs represent a great loss for both hatchery men and breeders. This experiment was done to study embryonic mortality and malpositions in Fayoumi.REVIEW OF LITERATUREA. Embryonic Mortality. Embryonic mortality occurs at any time from fertilization up to the time of hatching. Payne (1919) found that there was two peaks of embryonic mortality and reported that 65 percent of all embryonic mortality occurs between the fourth and the sixth day of incubation. In contrast, Byerly (1930) found that the first peak occurred on the third day of incubation. Byerly et al. (1934) reported that there was a minor peak at about the seventh day of incubation. Later on, they found another peak in the middle of the incubation period, which was related to nutritional deficiencies in the diet consumed by the flock. They also reported …
