Significant Difference

A total of 144, day old as hatched Cobb-500 broilers were fed adlibitum basis on a diet with 0%, 0.5%, 1.0% and 1.5% of Black Cumin Seed Meal up to 35 days of age to compare the effect of BCSM as herbal growth promoters on growth performance, meat yield characteristics and profitability of broilers. The experimental diets consisted of broiler starter and broiler grower, which were fed from 0-16 and 17-35 days of age, respectively. Diets supplemented with 1.5% BCSM showed significant effect on live weight at 21, 28 and 35 days of old in broilers in various groups as compared to that of control group. Better feed conversion (2.02) also noticed at 1.5% level of BCSM at early stage (14 days of old) of broilers. There was no significant difference (P>0.05) among the average live weight, dressing yield, thigh meat, wing meat, heart, gizzard liver, at 0%, 0.5%, 1.0% and 1.5% level of BCSM diet. But difference found within breast meat, drumstick meat, abdominal fat and skin of broilers at 1.5% level of BCSM diet. It may be concluded that supplementation of BCSM at 1.5% had the highest significant effect (P<0.01) on feed cost (Tk kg-1 b), production cost (Tk kg-1 b) and profit (Tk kg-1 b) and lower mortality. So that 1.5% BCSM in diets can be used for economic and efficient broiler production than 0.5% and 1.0 % level.SAARC J. Agri., 13(2): 151-160 (2015)

The effects of graded levels of corn distillers dried grains with soluble (DDGS) as partial replacement for soybean meal in diets for broilers were observed. In the first experiment 900 males of ROSS 308 were used and they fed diets with 0, 60, 120 and 180 g/kg DDGS in grower diets (Control group, D6, D12 and D18) from 9th to 35th day of age. In the second experiment 800 broilers both sex of COBB 500 were used and they fed diets with 0 and 200 g/kg DDGS in grower diets (Control group and D20) from 9th to 35th day of age. Until age 30th day there were not significant differences among the groups in live weight in the first experiment. But at 35th day of age the live weight of chickens fed 60 and 120 g/ kg DDGS (2498.5 g and 2496.3 g) was significantly higher (P < 0.05) than in Control group (2425.9 g, without DDGS). In the second experiment, from 23th to 35th day of age significantly higher (P < 0.05) live weight had group fed diet without DDGS in comparison with chickens fed 200 g/kg DDGS. The difference between groups at 35th day of age was 75.7 g. Feed conversion ratio was similar in all groups in both experiments. There was not observed significant effect of DDGS on weight and proportion of abdominal fat. Feeding DDGS had significant effect (P < 0.05) on decrease the lightness (L*) of breast meat in the first experiment, which was not confirmed in the second experiment.

A study was conducted to determine the meat production potential of Pekin (P) x Pekin (P), P x Desi (D) and P x Jinding (J) ducklings up to 8 weeks of age. 54 day old ducklings were randomly allocated to 3 genotypic treatments having 3 replications in each genotype. One duckling from each replication was dissected to determine the meat yield. The initial and final live weight was found highest (P<0.01) in P X P, followed by those of P X D and P X J ducklings respectively. Feed conversion was poor in P X J, better in P X P and best in P X D (P<0.01). However, feed conversion for all genotypes decreased with the advance of age. At all ages except 1st week, better feed utilization was observed in P X D crossbred than that in P X P and P X J. Higher breast meat was observed in P X P (P<0.05) than in P X D and P X J. Thigh meat was found higher (P<0.05) in P X P and P X D than that in P X J. Considering the growth performance (growth rate and feed utilization) and meat yield characteristics, it may be concluded that crossing of Pekin with local ducks might produce a suitable genotype to improve meat production potential of duck to reared under Bangladesh condition.

A total of 72 as hatched Cobb 500 broilers were fed ad libitum on a diet with 0 %, 0.5 %, 1.0 % and 1.5 % of coriander seed meal (CSM) to assess its feeding value. Treatment group with 1.5 % of CSM significantly (p<0.05) affected live weight of broilers at the age of 28 and 35 days. Among the dietary groups there is no significant difference in feed intake and feed efficiency. Meat yield characteristics especially abdominal fat level decreased significantly (p<0.01) at 1.5 % level of CSM. Cost of production per kg live broiler decreased when dietary inclusion level was increased. Profit per kg of live broiler was significantly (p<0.05) increased with the increase levels of dietary CSM. These results suggest that the CSM could be considered as a potential natural growth promoter for poultry, and showed the best responses at a 1.5 % level of inclusion. It was concluded that the supplementation of the coriander seed meal to broiler diet had beneficial effects on body weight gain, feed conversion ratio and carcass yield.DOI: http://dx.doi.org/10.3329/bjas.v43i1.19383 Bang.

A study was conducted to investigate the effect of dietary moringa leaf meal (MLM) as a natural alternative to antibiotic on the growth performance, meat quality and carcass yield of broiler chicken. A total of 270 day-old broiler chicks were randomly weighed and assigned to six dietary treatments having 45 birds in each. Each dietary treatment had three replicates of 15 birds and was reared in floor pens. Chicks were distributed in 4 different inclusion levels of MLM in diets; 0.5%, 1.0%, 1.5% and 2.0% with 2 control diets negative and positive. The birds were fed the experimental diets and water was provided without restriction throughout the experimental period. The results showed that significant (P<0.05) effect on final body weight and weight gain in dietary supplementation of 1.5% MLM as compared to that of control group. Better feed conversion (1.53) was observed at 1.5% MLM group. Different levels of MLM exhibit significant influence on meat yield performance of broilers. There was no significant difference (P>0.05) observed among the average live weight, thigh meat, wing meat, drumstick meat, gizzard and abdominal fat of broilers. Breast meat, heart, liver, large intestine and dressing percentage showed significant difference. Lower mortality was found on diet supplemented with MLM. It is concluded that 1.5% MLM in broiler diets can be used as natural feed additive for enhancing growth performance, organ development, meat yield and serum cholesterol of broilers as well as replacing of oxytetracycline.Asian J.

Abstract Two performance studies were conducted to investigate the effects of 3 different sources of Cu on production parameters of piglets. A total of 256 piglets weaned at 24 ± 2 d were randomly allocated into 4 treatments with 10 or 8 replicates per treatment of 4 or 3 piglets per pen in Exp. 1 and 2, respectively. The experimental period was divided into 3 feeding phases: Phase 1 (24 to 35 d), Phase 2 (36 to 49 d), and Phase 3 (50 to 70 d). Treatments included a Control group (fed 10 mg/kg of Cu from CuSO4), a group fed 160 mg/kg of either CuSO4 (CuSO4-160) or tri-basic copper chloride (TBCC), and a group fed Cu methionine hydroxy analogue chelated (Cu-MHAC) at 150, 80, and 50 mg/kg in Phases 1, 2, and 3, respectively. The methionine value of Cu-MHAC was accounted during diet formulation to achieve the same levels of methionine across treatments. Phases 1 and 2 diets contained 2,200 and 1,500 ppm of ZnO, respectively; and antibiotics were used as growth promoters. Performance parameters were analyzed as completely randomized block design, in which each experiment was considered as a block. In trial 2, blood serum and mucosal samples, from the fundic region of the stomach, were collected from 1 piglet per replicate at day 70 and tested for serum growth hormone levels (GH) and ghrelin mRNA expression, respectively. The contrast between Cu-MHAC vs. CuSO4-160 + TBCC showed that piglets fed Cu-MHAC exhibited better feed conversion ratio (FCR) in all feeding phases compared with feeding inorganic Cu (P < 0.05). Overall, feeding Cu-MHAC improved body weight (BW), BW gain, feed intake (FI), and FCR vs. Control diet fed piglets; yet, it improved BW and FCR vs. TBCC fed piglets, and improved BW, BW gain, and FI vs. CuSO4-160 fed piglets (P < 0.05). Feeding TBCC promoted similar performance than feeding CuSO4-160, regardless of age (P > 0.05). Both ghrelin expression and growth hormone serum levels were significantly increased by feeding Cu-MHAC vs. Control diet fed animals (P < 0.01). Feeding CuSO4-160 upregulated ghrelin expression vs. Control (P < 0.01) while GH serum levels and ghrelin expression did no change by feeding TBCC compared with Control diet fed animals (P > 0.05). It was concluded that feeding Cu-MHAC at the levels tested herein can improve growth performance of piglets beyond feeding 160 ppm of either CuSO4 or TBCC, which may be partially explained by the increased expression of ghrelin and GH serum levels.

Abstract Genetic selection for improved meat quality traits has been successfully implemented in many livestock species. The objective of this study was to estimate the heritability of several meat quality traits to assess their selection potential in turkeys. Pedigree toms (n = 1,033) were processed at a commercial facility and live weight, breast meat yield (as a percentage of live weight), ultimate pH, color (CIELAB values), drip loss, cooking loss, and shear force were recorded on M. pectoralis superficialis (fillet). White striping was also rated on a 1–4 scale. Heritabilities were estimated using univariate animal models in ASReml version 4.1. Hatch week and age at slaughter were included as fixed effects in the mode,l and 32 generations of pedigree records were used. Breast meat yield (h2 = 0.62; SE = 0.090) showed the highest heritability and was higher compared to previous estimates, probably due to the smaller sample size. Live weight (h2 = 0.31; SE = 0.078), ultimate pH (h2 = 0.36; SE = 0.087), lightness (h2 = 0.28; SE = 0.086), redness (h2 = 0.22; SE = 0.075), and white striping score (h2 = 0.27; SE = 0.085) all had moderate heritabilities. The estimate for ultimate pH was similar to previous studies in broilers but was high compared to previous studies in turkeys. Estimates for color were similar to those found in previous studies involving turkeys. Drip loss and cooking loss had similar heritability estimates of 0.13 (SE = 0.071) and 0.10 (SE = 0.064), respectively, which were akin to previous estimates in pork. Shear force (h2 = 0.02; SE = 0.056) was found to have a very low heritability. In conclusion, the heritability estimates provided in this study show great potential for the inclusion of meat quality traits in selection programs of turkeys. This study is part of a larger project working towards the implementation of genomic information in the selection of turkeys for improved meat quality.

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.

Phytogene feed additives (phytobiotics) are plant origin compounds used in animal nutrition in order to improve their productivity by improving the production performance of animals, feed properties and the quality of food of animal origin. These additives stimulate animal growth by using their natural and physiological potentials and mechanisms providing conditions for the realization of the genetically projected production volumes. Data on the use of phytobiotics as growth stimulators are incomplete and often very contradictory, especially those related to their impact on the health and performance of weaned pigs. Given the relevance and importance of these issues the feeding trial was organized by the group-control system. The experiment lasted for 40 days and it was divided into two phases of 20 days each. Trial was conducted on 24 piglets, F1 generation of Swedish Landrace and Pietrain, weaned from sows at the age of 35 days. Tests were carried out on piglets, with an average body weight of 8.61?1.59 kg, which were subjected to one of the two feeding treatments immediately after weaning. The control group was fed with a mixture without growth promoters, while the experimental group received a diet containing preparation of phytobiotic (Enviva EO 101, Danisco Animal Nutrition) in the amount recommended by the manufacturer (0.1 kg/t). The mixtures for piglets nutrition were formulated in accordance with the recommendations of the NRC (1998), and AEC (1993) and they met the nutritional requirements completely. During the experiment, there was no disturbance of health and/or the manifestation of clinical signs of disease. The control group, fed with the diet without added growth stimulators, achieved body weight (25.32?6.31 kg), average daily gain (0.42?0.12 kg), consumption (0.89 kg) and feed conversion (2.119 ) normal for a given race, age and housing conditions. The use of preparation of phytobiotics as growth promoters, led to better production results in regard to the control group, which was based on higher body weight (27.19?4.77 kg), higher average daily gain (0.46?0.09 kg) and better feed conversion (2.043). The use of phytobiotic, as an alternative option in growth stimulation of weaned pigs, has its nutritive, medical and economic justification.

The objective of our study was to test amaranth grain or dried biomass in the diet for broiler chickens as a resource of protein replacing animal protein. Further, the effect of amaranth on broiler performance, carcass characteristics and meat quality were assessed in a feeding trial. The experimental groups of broilers were fed feed mixtures with crude amaranth grain (AC), heat processed amaranth grain (AP) or dried above-ground biomass (AB). Control groups (C) received the diet containing animal proteins. The results obtained in the experimental groups of broiler chickens can be compared to the control group in all the production indicators under investigation. On day 42 of the experiment, live weight (g) of female broilers ranged from 2 205.1 &plusmn; 152.5 (AP) to 2 254.0 &plusmn; 136.5 (C), and that of male broilers from 2 375.1 &plusmn; 233.0 (AC) to 2 506.0 &plusmn; 286.0 (C). Feed conversion ranged from 1.80 kg in control group of male broiler chickens to 1.91 kg in experimental group of male broilers (AB). Percentage yield in female broiler chickens ranged from 70.8 &plusmn; 1.74 (AB) to 72.4 &plusmn;3.34(AC) or 72.4 &plusmn; 1.98 (C), and in male broilers from 72.8 &plusmn;3.55(AP) to 75.1 &plusmn;2.44(AB). Our results showed that amaranth can fully replace meat-and-bone meals in the diets for broiler chickens.

ABSTRACT A non-surgical sterilant (NSS) was used with the objective of assessing the zootechnical performance, carcass and meat quality, and hormone levels. 90 male piglets were selected with birthweights varying between 1.5kg to 2.0kg. The control group was constituted of 45 males castrated by the conventional surgical method, at the seventh day of age, and the treated group was constituted of 45 males castrated with NSS (active principle of zinc gluconate in the concentration of 26.2mg/mL associated to the dimethyl sulfoxide at 0.5%), with the application of the first dose on the seventh day of age and the second dose on the fourteenth day of age. The zootechnical assessments were carried out on the farm and consisted: weight gain in the periods per animal and feed conversion. The slaughter of the animals and the assessment of the carcass and meat quality and hormone levels were carried out in a slaughterhouse and the municipality of Campinas (SP). The study demonstrated that the use of NSS was a viable alternative in relation to the zootechnical performance and the carcass quality. In relation to the meat quality there was no significant difference in the majority of the assessed parameters.
