The effects of raw versus steamed navy bean (Phaseolus vulgaris) meal, in diets with and without methionine supplementation, on egg production, egg weight, body weight, pancreas weight, mortality, feed consumption and conversion, and energy and nitrogen utilization were determined with laying hens. As the level of raw navy bean meal in the diet increased, egg mass production and body weight gain decreased. Declines in production were largely overcome by steaming the bean meal. Methionine supplementation of both raw and steamed meal diets had no effect on performance. Changes in dietary metabolizable energy and nitrogen retention are discussed in relation to bird performance.

SUMMARYThree varieties of triticale (TL-238, TL-257 and TL-319) bred by the Plant Breeding Department of Punjab Agricultural University were studied for nutrient composition and metabolizable energy (ME) content for egg-type chicks. A feeding trial was also conducted to study the suitability of triticale as a replacement for maize in conventional high- and low-cereal diets for different classes of egg-type chickens.The crude protein contents of TL-238, TL-257 and TL-319 were respectively 13·4,14·4 and 2·1%. Corresponding values for starch content were 51·5, 49·2 and 54·3%, respectively. ME in triticale varieties closely followed the trend of starch content. Accordingly TL-319 was higher in ME (13·58 MJ/kg D.M.) than TL-238 and TL-257 (12·91 and 12·49 MJ/kg D.M. respectively). There were no significant differences in body-weight gain or in food conversion of chicks fed diets containing different varieties of triticale. The substitution of triticale for maize in a conventional high-cereal diet improved growth and food conversion of starter chicks. In a low-cereal diet, however, triticale had an adverse effect on the growth rate and food conversion of starter chicks. At the end of 18 weeks of age, the differences in body-weight gain, food conversion and efficiency of protein utilization by chicks on all the treatments were not significantly different (P > 0·05). Results of the production phase showed that egg production, egg mass, food conversion and energetic efficiency were significantly (P < 0·05) improved by feeding triticale.

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.

Six diets containing five levels of methionine and two of lysme were each fed to 12 Leghorn and 12 Australorp pullets for a period of 16 weeks Body weight changes, egg production, egg weight and feed intake were measured Although responses to the diets did not differ significantly In univariate analyses, multrvarrate analysis lndicated a srgnificant interaction between breeds and diets. Increased methionine produced small, significant Increases In egg weight, although responses were inconsistent at different levels Body weight gains were not significantly different between diets. Egg production and feed consumption were significantly affected by diet?, but the pattern of response was also inconsistent. A discriminate function analysis showed a consistent response to increased methionine, which indicated that the basal diet was deficient and that the pullets required a total of 0 275% methionine in their diet Lysine supplementation produced a 'significant decrease In feed intake but had no significant effect on any other variable.A multiple regression equation relating metabolizable energy intake to the variables measured in the experiment was calculated and compared with others reported In the literature This was used to predict the requirements of the pullets for a number of essential amino acids.

The purpose of this experiment was to know the effect of dl-methionine supplementation in feed on the body weight gain, feed consumption, and feed efficiency of broilers. The experiment was conducted at the Laboratory of Animal Husbandry Study Program, Agricultural Faculty, University of Timor, Kefamenanu from December 2019 to January 2020. The experiment used 80 fourteen-day broilers. The method used in this research was an experimental method with a completely randomized design (CRD) consisting of 4 treatments and 4 replications. The treatments given were: T0 (control feed), T1 (T0 + 0.30% dl-methionine), T2 (T0 + 0.50% dl-methionine), and T3 (T0 + 0.70% dl-methionine). The variables observed were body weight gain, feed consumption, and feed efficiency. The results of the experiment showed that the treatment significantly affected the body weight gain, feed consumption, and feed efficiency of broilers (P<0.05). It was concluded that commercial feed supplemented with dl-methionine by 0.70% increased the growth performance of broilers.

The post-molting performance of 360 female Japanese quails was assessed using five molting methods including feed restriction along with supplementation of dietary levels of aluminum sulfate (AlSO4) and zinc oxide (ZnO) with two concentrations of 0.15% and 0.3%. None of the parameters studied were positively influenced by a single molting method. Body weight gain and feed efficiency were positively affected by higher concentration of ZnO while feed consumption was positively influenced by higher concentration of AlSO4. Similarly high feed efficiency was attributed to higher concentrations of both ZnO and AlSO4. On other hand body weight gain and feed efficiency were negatively influenced by 0.15% ZnO while egg production was worst by 0.15% AlSO4. As each of the molting method had different influence on the tested parameters and none of them could apply individually with perspective of better performance therefore the combinational use of molting methods is recommended according to the focused parameter

Selection For

In egg-type poultry, variation in egg mass, body weight and change in body weight account for about 50–70% of the variation in feed consumed. In meat-type poultry, about 40% of the variation in feed consumption is attributable to variation in change of body weight (gain), and body weight itself. Past selection, primarily for egg numbers and egg size (egg mass) in egg stocks and for gain in meat stocks, has resulted in a correlated improvement in feed efficiency. Heterosis from breed or strain crosses contributes an average of 6% to improvement of feed efficiency in both egg and meat stocks. The success of direct selection for feed efficiency depends upon variation in feed consumption not attributable to economic traits in present poultry selection programs. There is evidence that such variation exists which could be successfully exploited in poultry. In egg stocks, the evidence is mainly from studies of variation within and between strains. In meat stocks, there is evidence from uni-trait selection studies as well as studies of within and between strain variation. The degree to which such selection would be successful in a multi-trait selection program and the economic viability of such success as compared to alternatives needs to be determined. Improvement of feed efficiency is possible by reducing feed requirements for maintenance and activity, by reducing behaviors causing feed wastage, or by reducing body fat to require less feed energy per unit gain. Feed wastage can be reduced by management techniques. Thus, the exploitation of feed-wasting behavior is not presently necessary. The best prospects are those associated with maintenance energy requirements in both egg and meat stocks of poultry, and the reduction of body fat in meat stocks. It is improbable that the opportunities for breeding to improve feed efficiency have been exhausted, much less identified. Key words: Breeding, feed efficiency, poultry, selection

Three hundred ten 12-wek-old laying quails (155 each) were randomly selected from the initial population and kept in individual battery cages. The measurements of growth and egg production were determined to derive RFI. The relationship between RFI and egg quality, blood parameters and carcass characteristics was also determined. The results indicated that the gray quails had significantly higher egg mass and lower broken eggs compared to the white quails. A significant increase for eggshell strength and shell % was found in eggs produced from gray quails compared to white counterparts, although the shell thickness was the same. The results of multiple regression analysis clearly identified a significant effect of metabolic body weight and egg mass in computing expected feed intake rather than body weight gain in both varieties of Japanese quails. Strongly positive correlation between RFI and feed intake in both gray and white quail varieties was found. The same trend was also observed for feed conversion ratio (FCR). Therefore, including RFI in selection criteria of Japanese quail to improve FCR under high environmental temperature is highly recommended.

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.

A study was conducted for 56 days to observe the effect of varied levels of dietary crude protein and metabolizable energy on growth performance in 720 day-old Giriraja chicks, which were divided equally into nine groups of 80 birds each. Nine different experimental diets were formulated with three levels 2700, 2800, and 2900 kcal of metabolizable energy (ME/kg), each with three levels of protein (CP), viz., 19%, 20%, and 21%, respectively and Group T5 served as control fed with 20% protein and 2800 kcal energy as per BIS (2007) requirements. Feed consumption, body weight gain, and feed conversion ratio (FCR) were analysed up to 56 days. The results of the study indicated that diet containing 20% CP with 2900 kcal ME/kg showed enhanced growth performance in Giriraja chicks.

An experiment was conducted with laying hens to determine the effects of feeding excesses of methionine in a practical layer diet. One hundred and thirty two laying hens at 61 weeks of age were used for the experiment. Two body weight groups (light and heavy) and three levels of mehionine were assigned to six groups of laying hen in a 2x3 factorial design. The diets were a 16.5% crude protein corn and soybean meal positive control diet (0.33% methionine), and this diet fortified with 1.00% additional DL-Methionine or 1.50% additional DL-Methionine. The diets were fed ad libitum to the hens for 10 consecutive weeks of production. For the total production period, body weight gain, hen-day egg production, egg weight, egg mass, daily feed intake and feed conversion ratio were not significantly different among any of the treatments in the two body weight groups (P>0.05). The study indicated that considerable tolerance exists in laying hens for individual excesses of the DL-Methionine commonly used as supplement in poultry diets.
