The present study was conducted to compare the growth performance of White, Black and Bronze color type of turkeys, which have been currently introduced in Bangladesh. The birds were reared under semi-intensive system at BAU Poultry Farm with supplementation of commercial broiler grower and layer feeds. Key objectives were to investigate the growth performance of locally found turkeys (known as heritage turkeys) under semi-intensive rearing system and to recommend turkey as a supplementary part of existing poultry business in the country. A total of 46 poults of White, Black and Bronze color type unsexed birds of 5 weeks age were housed. Birds were reared under similar management conditions and feeds were purchased from local market. No significant difference (p>0.05) in live weight for three color types were found. At the end of 21 weeks rearing, Bronze type turkeys attained highest live body weight (3720.71g/bird) while White type turkeys attained lowest (3282.29g/bird). The Black type turkeys however, attained 3552.86g/bird body weight. The live weight gain was increased gradually but decreased again after 18 weeks of age. Weekly weight gains were highest in all color types at 18 weeks of age where white type male turkey attained the highest (440.71g/bird) and black type showed the lowest weight gain (345.00g/bird). No significant difference (p>0.05) in FCR among the three color types were found. Survivability under semi intensive system of three different color types, White, Black and Bronze were 100%, 88.46% and 91.67% respectively. Taken together, the growth performance of Bronze type turkey was superior to other color types used in this experiment. Therefore, it can be concluded that turkey farming will viable in Bangladesh with available local varieties under semi-intensive system through feeding of commercial broiler and layer feeds. J.

AbstractEuropean (no. = 36) and hybrid (¼ Mesopotamian, ¾ European; no. = 36) fallow deer (Dama dama) were evaluated for weight gain and energy intake from 10 to 21 months of age. Twelve each of bucks, does and castrated males (haviers) were tested for each genotype, in both concentrate-fed and pasture-based feeding systems. Based on weekly weighing hybrids (H) in each of the sex classes grew more rapidly (5 g/day across all groups) than the European (E) fallow deer (P < 0·05). Haviers given concentrates grew significantly faster than pasture-fed haviers (P < 0·01), whilst does grown on pasture grew significantly faster than those given concentrates (P < 0·01). There was no significant difference in pattern of growth between bucks on pasture and those given concentrates (P > 0·05). Does grew significantly less (P < 0·01) than bucks and haviers in spring, summer and winter but environmental differences between years could not be accounted for in the analysis.Animals of all sexes and genotypes experienced rapid growth from 10 to 12 months of age (spring) and this was associated with energy intakes according to metabolic body weight (M0·75) these ranging between 0·8 and 1·1 MJ metabolizable energy (ME) per kg M0·75 per day. There were significantly (P < 0·01) higher levels of energy consumed by H does and haviers in the summer, compared with their E counterparts but this was not associated with greater growth rates. However, H does had significantly higher (P < 0·01) dressing proportions at slaughter than E does. The energy intake on a metabolic body weight basis for most groups declined to between 0·7 and 0·8 MJ ME per kg M0·75 per day from 12 to 21 months of age, except for the does, which declined even further to between 0·5 and 0·6 MJ ME per kg M0·75 per day from 17 months of age.There were no significant differences between E and H deer for energy intakes per M0·75, and H deer were slightly more energy efficient than their E counterparts in terms of growth rate in relation to annual gross energy intake. The food intake : weight gain ratio increased considerably for both genotypes after 14 months of age, indicating the desirability for slaughtering as soon as animals reach the target live weight. It was concluded that the crossbreeding system described is production efficient and produced offspring that reached slaughter weight sooner than E fallow deer and thereby produced carcasses with a greater wholesale value than their E counterparts of the same age.

Objective: The study developed mushroom stalk residues as feed additives in the broiler diet for improving the growth performance and immunity of broilers as well as to increase the value of mushroom stalk residues.Methods: In total, 300 ROSS 308 broilers were randomly allocated into fifteen pens with five dietary treatments: i) control, basal diet; ii) CMWM, supplemented with 1% <i>Cordyceps militaris</i> waster medium (CM); iii) CMPE, supplemented with 0.5% CM+0.5% <i>Pleurotus eryngii</i> stalk residue (PE); iv) CMPS, supplemented with 0.5% CM+0.5% <i>Pleurotus sajorcaju</i> stalk residue (PS); v) CMFV, supplemented with 0.5% CM+0.5% <i>Fammulina velutipes</i> stalk residue (FV).Results: The chemical analysis results showed that CM extracts, PE extracts, PS extracts, and FV extracts contain functional components such as polysaccharides and phenols and have both 2, 2‐diphenyl‐1‐picryl‐hydrazyl‐hydrate scavenging and Ferrous scavenging capacities. The group CMWM saw increased body weight gain and feed conversion rate and the promotion of jejunum villus growth, but there is no significant difference in the intestinal bacteria phase. Antioxidant genes in the nuclear factor (erythroid-derived 2)-like 2 (Nrf2)- antioxidant responsive element pathway among the groups are significantly higher than that of the control group, especially in group CMWM.Conclusion: The mushroom stalk residues have antioxidant functional components, can improve the intestinal health and body weight gain of chickens, and can activate the antioxidant pathway of Nrf2 to increase the heme oxygenase-1 expression. The treatment with 1% CM was the most promising as a feed additive.

Abstract This study aimed to determine the effects of increasing Methionine (Met) supply on growth performance and carcass traits of growing-finishing pigs under summer conditions in Brazil. A total of 200 barrows and females, 63 d-old (20.43±2.0 kg), were allocated in a 2 x 2 factorial design (two Met sources [DL-Met and OH-Met] and two Met doses [100 and 120% Brazilian Nutritional recommendation) with 10 replicates of 5 animals each. Corn-DDGS-wheat-soya based diets were formulated. Treatments were offered during four phases: growing I (63-93 d old), growing II (94-114 d old), finishing I (115-142 d old) and finishing II (143-160 d old). The recommended digestible Met levels were: 0.32, 0.30, 0.29 and 0.24% respectively for the four phases. Average temperature was 27.12 ± 4.51ºC and relative humidity was 61.72 ± 5.65%. Growth performance was measured for each rearing phase. Carcass yield, back fat height, loin depth, and lean meat yield were measured at the end of the experiment. Data were submitted to a 2-way ANOVA and Tukey test. There was no significant interaction between the Met source and the dose for all performance and carcass traits. Feed intake and feed conversion ratio were similar between treatments (P &gt;0.05). The individual daily weight gain and live weight were better for the highest doses of methionine (P&lt; 0.05) in all phases and on the whole period, except for the finishing II where the weight gain was similar for all treatments. Likewise, carcass yield, lean meat was increased with the highest dose of methionine in comparison to the adequate dose. No significant difference was found between DL-Met and OH-Met on growth performance parameters. OH-Met resulted in a higher loin depth (58.37 mm) in comparison to DL-Met (55.21 mm). Overall, these results demonstrated the interest of increasing Met supply under hot conditions to improving performance and carcass quality traits.

The aim of the current study was to evaluate cardiac status, ascites susceptibility, thyroid hormones, some hematological parameters and performance of five commercial broiler strains. Chicks were selected from strains of Cobb, Hubbard, Ross 308, Arbor Acres, and Arian (Iranian commercial broiler strain). Management and nutritional conditions were the same for all strains. Ascites related factors, and growth performance were measured. The highest and lowest, RV weight/live weight at 21 day of age were related to Arian and Ross 308 strains, respectively (p < 0.05). The TV weight, TV weight/live weight and the RV weight/live weight were significantly different between various strains at 49 and 54 days of age (p < 0.05). Strain had no effect on RV/TV. Performance, T3 and T4 hormones, hematological parameters, and mortalities were not significantly different among the strains (p > 0.05). Ascites mortalities in the Ross 308 was zero; however, it had no significant difference with other strains (p > 0.05). It was concluded that, based on performance and physiological status, even though considered broiler strains did not differ significantly because of the same genetic programs probably, but according to the prices and market conditions each can be selected for breeding.

The objective of this study was to evaluate the effect of recombinant bovine somatotropin (rbST) on average total weight gain, average daily gain, muscularity and finishing. 24 Nellore heifers were used, up to two years of age and weighing 307.4 kg. The animals were semi-confined in Brachiaria ruziziensis and were supplemented per day, with 1.5% kg live weight per animal feed. Heifers were divided into 2 groups, T1: with the use of rbST and T2: unused rbST (control). The rbST was applied every 14 days at a dose of 500 mg per animal. For the statistical analysis, the results were submitted to analysis of variance (ANOVA) at 5% significance level. There was no significant difference (p> 0.05) for average initial body weight, average final body weight, total average gain and average daily gain, and ribeye area (REA) adipose tissue thickness. Therefore the use of rbST did not promote change in performance characteristics in Nellore heifers 2 years old.

Background: Poultry rearing systems and feeding have been the emphasis of broiler raisers to in able to meet the costumers demand for high-quality products. In this study, free range management have been introduced that allows the birds to enjoy their natural habitat while utilizing vermi meal as supplemented to commercial feeds. Method: Evaluated the growth performance and profitability of broilers fed with different levels of vermi meal. Treatments represent T1- 100% Commercial Feeds (CF), T2- 2% Vermi Meal (VM)+98% CF, T3- 3% VM+97% CF, T4- 5% VM+95% CF. Treatment means having significant differences were subjected to Least Significant Difference at 5 % level of significance. Result: Vermi meal did not influenced the weight gain, feed intake, feed consumption and dressing percentage of broiler chicken. However numerically, final weight and weight gain in T4 containing 5% VM was higher than T1 with commercial feed a difference of 66. 66 grams and 67.60 grams respectively. Birds of T4 with 5% inclusion of vermi meal showed higher in most parameters compared to the group fed with commercial feed. Consequently, 5% level of vermi meal had an optimum result in final weight, gain weight, feed conversion ratio, feed consumption, live weight and carcass weight.

For studying the effect of accelerated feeding method on growth and carcass traits thirty male kids (aged 30 -45 days) of Tellicherry breed were divided into two groups, control (C) and test (T) groups. The control group kids were fed with concentrate feed consisting of 15% crude protein (CP) and 75% Total Digestible Nutrient (TDN). The test group kids were fed with concentrate feed containing of 21% crude Protein (CP) and 75% Total Digestible Nutrient (TDN). Significant (P less than 0.01) increase in body weight in average total body weight gain and average daily body weight were observed in both groups. Cost of production per kg live weight gain significantly (P less than 0.0001) reduced. High significant difference (P less than 0.01) was noticed in pre slaughter weight, carcass weight, dressed weight, dressing percentage, weight of stomach, head and liver. The present study concluded that feeding the kids with high protein level along with mineral mixure had significantly increased the body weight gain, growth performance, dressing percentage, carcass yield and quality.

A study was conducted to determine the growth performance and mortality rate of Khaki Campell, Jinding and Deshi genotypes in two coastal locations of Barisal and Bhola districts of Bangladesh. Sixty-day-old ducks of 3 genotypes were randomly allocated to 3 treatments having 4 replications in each. Ducks are reared up to 150 days and at the end of experiment one male Khaki Campbell of highest live weight was selected from each replicate group. The average weekly body weight gain (g/bird) of the Khaki Campbell and Jinding were significantly (p<0.01) higher than those of the Deshi ducks. The average body weight of Khaki Campbell (1480.25g) was slightly higher than that of Jinding (1428.25g) but significantly (p<0.01) higher than that of Deshi (1140.62g) ducks at the end of the experiment. The mortality rate were significantly different (p<0.01) in various genotypes. The highest mortality was found in Deshi (30.20%) compared to Khaki Campbell (19.79%) and Jinding (17.77%). The profit margin was significantly different (p<0.01) in three genotypes. The ducks reared in Barishal performed better (p<0.01) than that from Bhola. It may be suggested from the present findings that both Khaki Campbell and Jinding ducks are performed better than Deshi in the coastal region of Bangladesh.http://dx.doi.org/10.3329/bjas.v41i1.11971

ABSTRACT1. Four groups of British Friesian heifers born in April (no. = 30), July (no. = 29), October (no. = 30) 1977 and January 1978 (no. =27) were allocated to one of six treatments (planes of nutrition) at a mean age of 91 days. From 91 to 365 days of age heifers on treatments 1 to 5 were given individually, according to body weight, a proprietary pellet to 126 days of age, and thereafter a diet of dried lucerne and barley. Heifers on treatments 1 and 2 were fed at the same rate whereas heifers on treatments 3 to 5 were fed at successively higher rates. Heifers on treatment 6 were fed ad libitum the proprietary pellets to 126 days of age and thereafter a 'barley beef diet. Mean live-weight gains between 91 and 365 days of age for treatments 1 and 2 combined and 3 to 6, respectively, were 0·58, 0·68, 0·75, 0·82 and 1·06 kg/day.2. Plasma progesterone concentrations were determined twice weekly in each animal. Puberty was assumed to have occurred 2 days before the start of the first period in which the progesterone concentration exceeded 1μg/1 for at least 10 days.3. There was no significant difference between treatments in mean body weight at puberty (242 kg), but age at puberty (347, 305, 288, 301 and 239 days for treatments 1 and 2 combined and 3 to 6, respectively) was inversely related to rate of live-weight gain between 91 and 365 days of age. However, within each treatment group the fastest growing heifers reached puberty at the same age but at a heavier body weight than the slowest growing heifers.4. There were significant seasonal effects on age and body weight at puberty. The most rapidly reared animals (treatment 6) born in January and April were, on average, 52 days younger and 54 kg lighter at puberty than those born in July and October, but the effects of season of birth in other treatments were different.5. There was no significant difference between treatments in the number of conceptions (mean 0·67) achieved at first service by an Aberdeen Angus bull introduced when the heifers were 350 days of age.

This experiment was conducted to evaluate the efficacy of Neem (Azadirachta indica) leaf, Nishyinda (Vitex nogundo) leaf and Turmeric rhizome (Curcuma longa) powdered supplementation in drinking water as a growth promoter in broiler chickens. A total of 40 day-old Cobb 40 broiler chicks were purchased from local hatchery (Nourish Poultry & Hatchery Ltd.) and after seven days of acclimatization chicks were randomly divided into two groups, A and B. The group A was kept as a control and not treated. The group B was supplemented with Neem, Nishyinda leaves and Turmeric dried powder with feed and water. Weekly observations were recorded for live body weight gain up to 5th weeks and hematological tests were performed at 7th and 35th day’s age of broiler to search for hematological change between control (A) and treatment (B) groups. The initial body weight of groups A and B on 7th day of this experiment were 130±4.35 gm, respectively and after 35th day of experiment final body weight were 150±47.35 gm and 1600±58.56 gm, respectively; the net body weight gain were 1320±43.79 gm and 1470±54.25 gm, respectively and economics of production were analyzed and found that net profit per broiler was Tk. 17.24 and Tk. 30.00, respectively. The treatment group B was recorded statistically significant (at 1% level) increase for live body weight than that of control group A. The hematological difference, while Hb. estimation does not show significant difference from control group. The results suggest that better growth performance could be achieved in broilers supplemented with Neem, Nishyinda leaves and Turmeric rhizome extract.Res. Agric., Livest.
