Gain Loss

The relative economic weight (REW) of a trait is the additional gain/loss from a unit change in the trait relative to other traits in an individual. They are used to calculate aggregate economic values for purposes of genetic improvement in animals. The present study was designed to evaluate the bio-economic variables of growth and 16 weeks egg production parameters: egg number (EN16) egg weight (EWT16) body weight at first egg (BWTFE), body weight at 16 week of lay (BWTE16), cost of feed, and revenue from eggs and chicken carcass, 16 feed conversion ratio (FCR ), and body weight gain (BWG16) in the Nigerian indigenous chicken, and to determine the economic weights (EW) and REW of EN16, EWT16 and BWTE16 for G0, G1, and G2 generations. A total of 250 pullets (20 week old, point of lay) from a population of heavy body weight local chickens were used for the study. The birds were housed individually in cages, fed optimally on layers mash (G and G : 100g/bird/day; G : 0 1 2 125g/bird/day) and given water ad libitum. Data included EN , EWT , BWTE , BWTFE, 16 16 16 and prices of feed, eggs and spent hens, FCR , and BWG . Data on EN , EWT , BWTE , 16 16 16 16 16 and BWTFE were compared across generations using ANOVAand with other variables were used to generate the EW of the traits. The EW were then standardized relative to that of BWTE . Results showed that EW and REW of EN , EWT , and BWTE were 7.47 and 3.15, 16 16 16 16 13.67 and 5.77 and -2.37 and -1.00, respectively in G ; 13.07 and 3.82, 23.69 and 6.93, and - 0 3.42 and -1.00, respectively in G ; 16.80 and 2.89, 30.75 and 5.28 and -5.82 and -1.00, 1 respectively in G generation. Thus EN and EWT enhanced while BWTE depressed the 2 16 16 16 worth of the hen as a layer. EWT was more important than EN and both were more 16 16 important than BWTE economically. Therefore, EWT and EN are the major bio-economic 16 variables of the local hen as an egg chicken.

Hybrid Layers

One hundred and thirty-five fifty-two-week-old hybrid layers (Hubbard Strain), were allocated to 9 dietary treatments of 15 birds each. The birds were fed, on one of 9 diets, consisting of three levels of supplemental copper: 0,200 and 400 ppm and three levels of supplemental iron: 0,100 and 200 ppm for 12 weeks. Per cent day egg production, egg grade, feed intake, efficiency of teed conversion, mortality and body weight change were measured. No significant effects of copper or iron or their interaction, were observed for any of the traits measured in the study. However, diets supplemented with 100ppm Fe/400ppm Fe/0 ppm Cu, showed slight improvements in egg production and efficiency of feed conversion over the control. The diet supplemented with 100ppm Fe/200ppm Cu also showed the most marked body weight gain. The results of this study seem to indicate that the effects of copper supplements, equivalent to those found to stimulate growth in pigs and chicks, are of little or no significance in old layers in a tropical environment. The results also showed that concurrent supplementation of copper containing diet with iron is not necessary for old layers.

AbstractThe present investigation was carried out to estimate the effects of genotype and sex on growth and laying performance and assess the variations in plasma constituents in the tested genotypes and their relations with productive traits after four generations of selection. Data of growth and laying performance on 1440 females and males of Japanese quail were taken from the three quail genotypes: maternal (MG), long shank length (LSG28) and control (CG) genotypes. Genotype significantly affected all studied growth productive traits, favouring selected genotypes. The LSG28surpassed MG in total protein, albumin (Alb), globulin (Glob), triglycerides and Alb/Glob ratio and lowered both cholesterol and total lipids (TL). Sex significantly favoured females, which had higher body weight, longer shank length at 35 days of age and higher body weight gain during the period from 1 to 35 days of age. Females showed significantly higher concentrations of both Alb and TL than males. The MG exceeded LSG28in fertility and hatchability per cent. Correlations for both growth and productive traits with plasma constituents revealed inconsistent trends in either magnitude or direction. Four generations of selection resulted in substantial phenotypic improvements in most growth and productive traits, as well as plasma constituents studied in LSG28, and favoured MG in maturity, days needed to produce the first ten eggs, higher egg production per cent and heavier egg mass.

Economic Efficiencies

Production performance and economic efficiencies of broiler of Cobb 500, cockerel of ISA Brown, Fayoumi, and RIR (Rhode Island Red) and Sonali (derived from RIR? × Fayoumi?) available in Rajshahi were investigated. Identical care and management practices were provided to chickens of all genetic groups reared for meat and egg production. Performance of four meat purpose chickens viz., Cobb 500, ISA Brown, Fayoumi and Sonali were evaluated in terms of such important parameters as initial body weight (IBW), 5-wk rearing period (RP), achieved body weight (ABW), feed intake (FI), body weight gain (BWG) and feed conversion ratio (FCR). Performance of three egg purpose chickens viz. Fayoumi, RIR and Sonali included weight of day-old chick (WDOC), growth rate (GR), death rate (DR), fertility (FR), hatchability (HT), first laying age (FLA) and monthly egg production (MEP). Economic efficiency parameters viz., total cost (TC), gross return (GRR), net return (NR) and cost-benefit ratio (CBR) were calculated for both types. In terms of FI, FCR and BWG values, broiler of Cobb 500 was the best preferred and cockerel of ISA Brown the least preferred chicken. Conversely, in terms of the CBR values for meat producers, the cockerel of ISA White (1.58) was the best and the broiler of Cobb 500 (1.15) the worst. Taking the FLA and MEP into account, RIR topped the list (19.1 wks and 23 eggs per month) whereas Cobb 500 ranked at the bottom (25.2 wks and 16 eggs per month). CBR for egg productivity, on the other hand, was highest in Sonali (1.11) followed by RIR and Fayoumi (1.10 each) and Cobb 500 (1.09). As regards the meat productivity, significant correlations existed between TC and NR for all chickens except Sonali, which exhibited a negative correlation between the traits. Negative and non-significant associations prevailed for egg productivity in all the chickens. Although broiler of Cobb 500 was found to be the most popular for meat and RIR for egg, the cockerel of ISA Brown was the chicken that earned the maximum CBR.DOI: http://dx.doi.org/10.3329/ujzru.v31i0.15374Univ. j. zool.

Feed Conversion Rate

Hungarian goose production and gene conservation practices have been a tradition in Hungary for several centuries. The old Hungarian geese can only be effectively maintained if the national programs can identify economic uses of the breed. This study aimed to examine the potential use of the Hungarian landrace goose (HL) either as a purebred or crossbred with the Hungarian Upgraded breed (HU). Crossbred offspring were produced by HL ganders and HU layers, as egg production of HL layers is very low. Reproduction traits (egg production, fertility and hatchability) of parent stocks, body weight gain, feed consumption and slaughter values (slaughter loss, breast and thigh weight and proportions) and of offspring were measured. The results showed that fertility in the crossbred geese was insignificant compared to the fertility of HL purebreds, while hatchability of crossbreds was higher than that of purebred HL or HU. HL offspring had significantly lower bodyweight and weight gain, and a higher feed conversion rate than HU. The proportion of valuable meat parts (breast and thigh) was the highest in HU while weight in slaughter loss was also the highest in HU. In terms of body weight, feed conversion rate and slaughter properties, crossbred offspring showed intermediate  inheritance. HL is recommended for crossbreeding with HU breeds and their offspring should be reared under free-range keeping conditions.

Restrictive Diet

A diet containing 10 per cent protein and 11.31 MJ M.E. kg-1 was fed to six groups of eggtype pullets from either day old or four weeks for 8, 12 and 16 weeks in both summer and winter. The same diet was also fed to another group from 8 to 20 weeks of age in both seasons. During the rest of the rearing period of each treatment a diet containing 16 per cent protein was fed to 20 weeks of age. The control group was fed a diet containing 20,16 and 12 per cent protein and 12.1 5 MJ M.E. kg-1 from day old, 6 and 14 weeks of age respectively. In both seasons, feeding the restrictive diet resulted in a reduction in the cost of feeding and in body weight gain to 20 weeks of age; and a delay in maturity compared with the control without adversely affecting egg production traits or increasing food consumption during the laying phase. Pullets fed the restrictive diet from day old ate less food during rearing, matured later and tended to lay smaller eggs throughout the laying period than their counterparts which were restricted from four to eight weeks of age in both experiments. Food consumption was not affected by the duration of restriction in either rearing season. However, feeding costs and body weight of pullets at the end of both rearing seasons were reduced progressively by increasing the duration of restriction. Rate of mortality was not affected by the rearing treatments when the birds were reared in summer, whereas in winter pullets restricted from day old for 12 to 16 weeks had the higher rate of mortality. Mortality during laying was not affected by the rearing treatments in either season. The results of both experiments suggest that for maximum return the optimum age for feeding the low protein diet is from 4 to 20 weeks of age in either season.

A crossbreeding experiment between Hilly, a locally adapted chicken type in Bangladesh and Fayoumi, an egg type light chicken breed was carried out to evaluate phenotypic performances and to estimate genetic parameters for body weight and egg production at sexual maturity. Results show the mean hatch weight of Hilly♂ × Fayoumi♀ (H♂×F♀) crosses was 35±0.1 gm. In this study, H♂×F♀ crossbred showed a heavier body weight (1551± 32.0 gm/bird) at 20 weeks in comparison with other indigenous chicken genotypes in Bangladesh. The highest body weight gain was found in 8-10 weeks of age. H♂×F♀ crossbred hens exhibited sexual maturity at an average age of 147.5±1.6 days with an average body weight of 1350± 16.8 gm/bird. The mean weight of eggs at sexual maturity was 33.7±0.5 gm/egg. The estimates of heritability for body weight were ranged from 0.15 to 0.26. We observed a positive genetic correlation between weight at sexual maturity (WSM) and egg weight at sexual maturity (EWSM), meaning that hens with high weight at sexual maturity would produce heavier eggs.Asian J.

AbstractIn order to evaluate the effect of diet supplementation with Moringa oleifera leaf meal (MOLM) on growth and laying performances of quail in soudano-guinean zone of Cameroon, a study has been conducted in Ngaoundéré from May to September 2018. For this purpose, a total of 168 seven weeks old quails were divided into 12 comparable batches of 10 females and 4 males. Each of the four experimental diets (T0, T1, T2 and T3), formulated on the basis of the level (0, 1, 2, and 3% respectively) of diet supplementation with MOLM was randomly assigned to 03 batches in a completely randomized. Data were collected during the 16 weeks of the study on feed intake (FI), body weight (BW), body weight gain and feed conversion ratio. Weekly, after total laid eggs evaluation, 40 eggs per treatment was randomly chosen, weighed and measured. Main findings revealed that FI was not significantly affected by the diet supplementation with MOLM. Significantly higher BW and BW gain was recorded in T1 treatment compared to others treatments while they remains similar between them. The relatively heavier eggs were noted in T2 treatment while the highest (88.57 ± 2.85%) weekly laying rate was recorded with 1% supplementation. It has then been concluded that MOLM could be used as diet supplement during laying phase up to 3% for egg production and 1% of substitution seem to be the most appropriate to increase eggs laying rate while 2% is suitable to obtain heavy eggs in the soudano-guinean agro ecological zone of Cameroon.

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.
