The study was conducted to determine effect of egg-weight on hatchability and subsequent growth performance of Fayoumi breeds. A total of 576 eggs were purposively selected and arranged into three groups of small, medium and large sizes each with 192 eggs. Each egg group was randomly sub-divided into three replicates of 64 eggs in a CRD. Eggs were incubated for 21 days and chicks hatched on the same day were counted and individually weighed. Chicks were intensively raised on deep litter system for eight weeks on same diet, but kept separately according to their initial treatment of eggs. Data was analyzed by GLM of SAS and separated for means by Duncan’s multiple-range test. The study result revealed that egg size had effect on hatchability and strongly influenced all parameters measured during the brooding periods. It has significant effect on day-old weight, body weight, final weight gain, final feed conversion and mortality. Chicken producers may opt for medium-sized eggs principally for the purpose of better hatchability and feed conversion ratio whereas large sized eggs for better hatchling weight, weight gain and survivability. It is also recommended that future work may also address the effect of egg size on the same parameters at grower or pullet stage performance and specific diseases which cause paramount chick mortality should be identified.

Abstract Background An effort was made to assess the effectiveness of dietary supplementation of Ulva lactuca (U. lactuca), a seaweed and Azolla individually and in combination on different physiological parameters of Aseel chicken. A total of 40 Aseel chicks of 8 weeks old were allocated into four groups, C1 (control), T1 (Azolla alone), T2 (seaweed alone) and T3 (seaweed plus Azolla). Aseel chicks in C1 were fed with formulated grower feed alone, birds in T1 had control diet with 5% Azolla, birds in T2 had control diet with 3% U. lactuca and birds in T3 had control diet admixtured with 5% of Azolla and 3% of U. lactuca. Parameters were recorded for a continuous period of 2 months in 15 days interval. Results The growth performance was found to be significant (P ≤ 0.05) during 30 days of feed trials and highly significant (P ≤ 0.01) during 45 and 60 days of treatment. Birds in T3 had a higher body weight gain, shank length and feed conversion efficiency followed with T1 and T2 compared to C1. PCV, RBC, WBC and heterophil counts were not influenced (P ≥ 0.05) by dietary treatments. Uric acid, creatinine, AST, glucose, triglycerides and magnesium levels revealed a high significant (P ≤ 0.01) variation, and cholesterol level showed significant (P ≤ 0.05) changes during 30th and 60th day of feed trials between the control and treatment groups. Total protein, globulin, phosphorus and electrolytes like Na, K and Cl levels were not significant (P ≥ 0.05) during 30th day and were highly significant (P ≤ 0.01) during the 60th day of the trial. Conclusions It could be noted that inclusion of U. lactuca and Azolla as feed supplement in grower chicken had a better body weight gain when given in combination (U. lactuca and Azolla) rather than supplemented with the sole entity. Based on the haematological and serum biochemical analysis, the supplementation of U. lactuca and Azolla at the levels included in this trial did not pose any threat to the physiological well-being of Aseel chicken.

The purposes of determining the influence of the light and sexing on growth performance and slaughter results atyoung quails from Balotesti population, was organized an experiment on 150 quails, betwen age of 28 and 70 days. The chicks were divided into two groups (control and experimental), and growth and slaughter performance were determined separately by sex. Have studied 2 lighting programs, a program of continous lighting with photoperiod duration of 16 hours (16 L + 8 N, control group) and a program with lighting with asymetric hours intervals with photoperiod duration of 16 hours (10L+2N+6L+6N, experimental group).Males and females from the experimental group were recorded average performance of growth high during the period 28 - 70 days. Live weight at age of 70 days was higher with 7.54 %, average weight gain was higher with 14.86 % and feed conversion rate was lower with 13.51 % at males from experimental group compared to males from the control group. Also, the live weight at the age of 70 days was higher with 18.09 %; average weight gain was higher with 35.12 %, while feed conversion rate was reduced with 30.08 % on females from the experimental group compared to females from the control group.The results of the slaughter at 70 days were superior in the caseof females from the both groups versus males. The average weight of the carcase was higher with 17.53 % in case of the females than that of males from the experimental group, and the carcase yield was 65.37 % at the females and 65.56 % for males. Also, the average weight of the carcase was higher with 5.08 % in case of females compared to that males from the control group, and the carcase yield was 64.20 % to females 66.70 % on males.Superior results recorded in the case of females and males from the experimental group recommended the program of lighting with asymmetric hours intervals in the growth of youth quail. Also, the higher slaughter results recorded in the case of females of the two groups recommended them in the meat production through a broiler of quail that combine advantages in the production of both males and females.

 Best diet of the fish is the sole of production of aquaculture. Growth performance of Clarias gariepinus on the basis of formulated feed supply was carried out from 7th March to 6th May, 2019 in the laboratory of P.G.Campus, Biratnagar in which 130 juveniles (each of 10±0.11 g.) of catfish were cultured in 13 aquaria feeding with treatment diets having crude protein level 35%, 40%, 45% and 50% for treatment and commercial diet for control. There are no significant differences between the water quality parameters and body weight gain (p>0.05) in all treatments. The highest body weight gain (7.31±0.11 g; 65.20%) and SGR (13.051±1.15 g) was observed in fish fed with T C (45% protein level). This value was lowered than value of control(C) i.e. 7.59±0 g; 69.88% and 13.55±0 g respectively. Feed conversion ratio (FCR) was best (13.28±1.89 g) in T D (50% protein level feed). Its value was larger (7.52±1.11 g) in T C than C (7.15±0 g). Mortality rate was highest in T C and C i.e. 30% and lowest in T A and T B i.e. 23.33%. Weight gain of the fish increased with increasing protein level in diet till crude protein level 45% then it was dropped at the diet with protein level 50%. The best weight gain was observed in 7th week having crude protein level 45%. The diet with protein level 45% is suggested for farmers concerning the fish (Clarias gariepinus) in the aquaculture.

This study aimed to assess the effects of different levels of Trichanthera gigantea leaf meal (TGLM) supplementation on the growth performance of Philippine Native chickens fed commercial chicken grower ration. A total of 96 three-month old native chickens of two sexes were randomly distributed to the four treatments with 3 replicates and 4 chickens per replicate in a 2 x 4 factorial in Completely Randomized Design (CRD). Under semi-confinement system, the dietary treatments consisted of 0, 5, 10, and 15% levels of TGLM supplementation for 13 weeks. Results revealed that cumulative voluntary feed intake (VFI) increased as TGLM supplementation increased, and was significantly highest with 15% level at weeks 10, 11 and 12. Although differences were not significant except at weeks 4 and 7, there was a decreasing trend in cumulative weight gain (CWG) with increasing TGLM level. Average daily gain (ADG) was not significantly affected by varying levels of TGLM supplementation, and feed conversion efficiency (FCE) showed a decreasing trend as TGLM level increased and was only significantly low (p<0.01) with 15% level at week 7. Comparing between sexes, the males were significantly higher than females in all production performance parameters. Therefore, TGLM is palatable but not adequate enough to supply the nutrients needed for a comparable weight gain with that of 0% supplementation, and a 5 10% inclusion in the diet is recommended.

This study was conducted to assess the effects of abattoir wastes (bovine blood and rumen content mixture) on the haematology and growth performance characteristics of broiler birds. One hundred and twenty (120) unsexed day old Abor acre broiler chicks were randomly assigned to 4 treatments and replicated 3 times in a completely randomized design (CRD) experiment. Four experimental diets were formulated to meet the nutrient requirement of broilers such that the birds were fed sundried abattoir waste (bovine blood and rumen content mixture) included at 0%, 5%, 10% and 15% representing Diet 1, 2, 3 and 4 respectively, with Diet 1 as the control. Each dietary treatment consists of 30 birds with 10 birds per replicate. The experimental diets and clean water were supplied at- libitum throughout the experimental period. Data were collected on feed intake, daily weight gain, final body weight, weight gain. Feed conversion ratios were calculated. Blood samples for hematology was collected, analyzed and recorded. At the end of the 56 days feeding trials, data collected on different parameters were subjected to analysis of variance (ANOVA). Results showed that mixtures of bovine blood and rumen content significantly (P<0.05) improved the final weight (1767.02g -1931.44g), weight gain (1367.02g -1528.44g), feed intake (107.47g -118.99g) and feed conversion ratio (4.87 – 4.08) of the broilers. Significant (P<0.05) improvements were observed on the RBC, WBC, MCV, MCH, eosinophyls and the lymphocytes of the haematological parameters of the broilers. These results showed the complementary potentials of bovine blood and rumen content mixture in broiler diets, which can be included up to 15% in the ration of broilers without detrimentally affecting the growth performance and haematology of the broilers.

AbstractThe right-angled triangle mixture experiment was designed to include fourteen diets with different concentrations of starch, protein and lipid. Experimental diets were offered to male Ross 308 broiler chickens from 10 to 23 d after hatching, and response curves and surfaces were generated to illustrate the influence of macronutrients on growth performance and nutrient utilisations. Despite the primary function of macronutrients, especially protein, may not be providing energy, macronutrients were expressed as energy derived from starch, protein and fat for statistical purposes in the mixture design. Energy derived from lipid had a greater impact on feed intake than energy derived from starch and protein. When we compared the influence of starch and protein on feed intake, ‘equal distance rule’ was observed, which means the animal consumes feed to the point on its respective nutritional rails where the shortage of starch exactly equals the surplus of consumed protein. Increasing the protein-derived energy intake increased weight gain in broiler chickens, whereas energy intake derived from starch and lipid had little impact on weight gain. Feed conversion ratio (FCR) may be reduced by either increasing protein energy intake or decreasing starch energy intake. As the slope of the contours was less than 1, the influence of starch energy intakes on FCR exceeded that of protein energy intakes. In conclusion, energy derived from protein is more important than non-protein energy in terms of weight gain, and a balance between protein and energy supplies is required for efficient muscle protein deposition.

The aim of the present study was to assess effects of selenium (Se)-yeast diet supplementation on performance and carcass composition in ducks. The study was performed on 240 1-day old ducklings of the same origin (Cherry Valley hybrid), during a 49-day period, which were fed diets supplemented with the following four different levels of Se yeast (ALKOSEL® R397): groups with Se at 0 mg/kg of the diet as-fed, 0.2 mg/kg, 0.4 mg/kg and 0.6 mg/kg. Growth performance (bodyweight, daily weight gain, daily feed intake, feed-conversion ratio) and carcass characteristics (hot and cold carcass weight, chilling losses, dressing percentage, carcass cut yields, and percentage of tissues in breast and thighs with drumsticks) of the ducks were determined. Animals fed high-Se diets (0.4 mg/kg) had higher (P &lt; 0.05) final bodyweight and daily weight gain (from 15 to 49 days) compared with those fed diets with inadequate (0 mg/kg) or with supranutritional (0.6 mg/kg) Se levels. Ducks fed only with basal diet showed a higher (P &lt; 0.05) feed-conversion ratio (from 15 to 49 days) compared with those supplemented with Se at 0.4 mg/kg and 0.6 mg/kg. Dressing percentage was higher (P &lt; 0.01) in the control group (69.50%) than in the group with Se added at 0.6 mg/kg (66.85%). The weights of basic cuts from the duck carcasses did not significantly differ among compared groups. Moreover, the percentage of skin with subcutaneous fat in breast and thighs with drumsticks increased in Se-supplemented groups compared with the control group, while the opposite was determined with the percentage of muscle. It was concluded that a diet containing 0.4 mg of added Se per kilogram produced the greatest growth-performance results in ducks.

Abstract Yarrowia lipolytica yeast can be a valuable component of feed compounds due to its high content of protein and essential amino acids, as well as minerals. The objective of the study was to verify the research hypothesis that Yarrowia lipolytica (YL) yeast, having a more valuable chemical composition than Saccharomyces cerevisiae (SC), can improve growth performance in piglets. An attempt was made to determine what proportion of YL yeast in a compound feed for piglets would produce measurable effects in terms of production and health. The experiment was carried out on 46-dayold piglets receiving experimental mixtures for 39 days. The piglets in the experimental groups were fed the same mixture as the control, but with 3% or 6% fodder yeast of the strain Yarrowia lipolytica A-101 in place of soybean meal. The YL fodder yeast had significantly higher content of alanine (by about 50%), lysine, isoleucine and tryptophan (over 30%), leucine, valine, glycine and glutamic acid (over 20%), and tyrosine (by about 17%) in comparison with SC yeast. Content of crude fat was three times higher than in SC yeast. YL yeast had significantly higher content of Na+, K+, Ca+2, Mn+2, S, Mg+2 and Zn+2 than SC, as well as significantly higher content of vitamins B2 and E. Yarrowia lipolytica fodder yeast introduced to compound feed in the amount of just 3% improved growth performance (an increase in daily weight gain and a decrease in feed conversion per kg weight gain). These results indicate that YL in the amount of 3% in compound feed can be successfully used in the diet of piglets in place of the commonly used SC.

The objective of this study was to develop the least-cost starter&rsquo;s diet and evaluated its effect on the growth performance of Sasso breeds and Indigenous ecotype of chicks under the local condition of the South Gondar Zone. The effects of substitution of different levels of commercial starters ration with homemade diet on the growth performance of Sasso and Indigenous chicks were studied in Hiruy Abaregay village of Farta district. The research area is 586km distant from the capital city of Addis Ababa, Ethiopia. A total of 510 Sasso T-44 and 90 Indigenous local ecotypes day-old chicks were randomly divided into five groups, each with 102 and 18 chicks, respectively. These were assigned into five treatments in which 100 (T1), 75 (T2), 50 (T3), 25 (T4), and 0% (T5) of commercial starter&rsquo;s diet in factorial completely randomized design (CRD) with 3 replications for 60 days feeding period. The results obtained indicated that increased levels of substitution of a commercial diet with a homemade diet significantly depressed (p&lt;0.001) mean daily feed consumption and retention of dry matter, nitrogen, and metabolizable energy. Growth rate as measured by mean daily weight gain, mean final body weight, and total feed consumption and feed cost were significantly miserable (p&lt;0.001) in an increased homemade diet. On the contrary, there was an increase in feed conversion ratio and fiber content in high-level dilution of starter&rsquo;s commercial diet with a homemade diet. However, the groups of chicks on 0, 25, and 50% commercial starters diets replaced by homemade diet were significantly higher (p&lt;0.001) in mean daily feed intake, daily weight gain, feed conversion ratio, and final body weight attained. The results of this study indicated that up to 50% of expensive commercial starter&rsquo;s diet could economically be replaced with the least cost homemade diet without adversely affecting the growth performance of chicks.
