In this study, the effect of three different sources of maggot meals was conducted to evaluate the performance and slaughter characteristics of broiler chickens. Five diets were formulated to include Diet 1 (control) which contained 3.5 % fish meal, while Diets 2, 3 and 4 contained 3.5% maggot meal from broiler droppings (BMM),maggot meal from layers droppings (LMM) and maggot meal from rabbit faeces (RMM) respectively. Eighty (80) dayold unsexed Marshall Broilers were randomly allotted to four dietary treatments in a completely randomized design (CRD). Thedietary treatments had 20 birds each with two (2) replicates. Data were generated on proximate analysis and performance indices including feed intake and weight gain, slaughter characteristics and mortality rate. They were subjected to analysis of variance (ANOVA) and means significantly different were separated using Duncan's Multiple Range Test (DMRT) at 5% probability level. Results from proximate analysis showed that maggots from layer droppings had the highest crude protein and ether extract. Results on performance indices showed that birds fed on diet 3 (layer maggot meal) had significantly (P<0.05) best performance than others as regards feed intake. Layer maggot meal (LMM) in this study enhanced bestproductive performance compared to those from broiler and rabbit maggot.Birds fed layer maggot meal had the best (1.85) feed conversion ratio. They also had the best body weight gain (2501g) and feed intake (4627g). In conclusion, layer maggot meal is recommended as analternative animal protein source to expensive fish meal.

Foram avaliados os parâmetros zootécnicos de frangos de corte alimentados com dietas suplementadas com diferentes fontes e níveis de selênio (Se), criados sob diferentes condições de temperatura. Foram utilizados 720 pintainhos, Cobb-500, em um delineamento inteiramente ao acaso em esquema fatorial 3 x 2 x 2 (3 temperaturas ambiente: termoneutra, fria e quente; 2 níveis de suplementação de Se: nível A e B; e 2 fontes de Se: orgânica e inorgânica), com 4 repetições de 15 aves. Os níveis A e B de Se na ração inicial (1 a 21 dias) e de crescimento (22 a 42 dias) foram 0,15 e 0,30 mg/kg e 0,20 e 0,40 mg/kg, respectivamente. Selenometionina foi usada como fonte de Se orgânico e selenito de sódio, inorgânico. Os frangos criados em condições de estresse por calor apresentaram uma redução no consumo de ração e ganho de peso. Não houve influência da suplementação das diferentes fontes ou níveis de Se no ganho de peso, consumo de ração ou conversão alimentar. Os resultados são indicativos de que a suplementação de Se não melhora o desempenho de frangos de corte criados em condições de temperatura adversa. Evaluation of different sources and selenium levels for broilers at different temperatures Abstract This study evaluated the effect of selenium (Se) diet supplementation on productive parameters of broiler chickens raised under different temperatures, in a complete randomized design with 3 x 2 x 2 factorial schedule (3 environmental temperatures: cold, neutral and hot; 2 levels and two Se sources) with 4 repetitions of 15 birds. The levels of Se in rations for initial and growth phases were: 0.15 and 0.30 mg/kg; and 0.20 and 0.40 mg/kg, respectively. The organic and inorganic sources of selenium were selenomethionine and sodium selenite, respectively. There were a reducing in broiler feed intake and weight gain of the broilers housed in the hot temperature. Selenium levels or sources did not affect the weight gain, feed intake or feed conversion. It was concluded that Se supplementation did no affect the broiler performance, housed under adverse environmental temperature.

This study aimed to assess the effect of stocking density of 10, 12, 14, and 16 birds m?2 on performance, carcass and cut yields, productivity, and bone development of broiler chickens Cobb 500®. The experimental design was completely randomized design with four treatments (stocking densities) and four replications. The assessments were performed weekly at 1, 7, 14, 21, 28, 35, and 42 days. The best live weight result was found at a density of 10 birds m?2 in the period from 1 to 7 days. No effect of density was observed on feed intake and weight gain. From 1 to 14 days, the best live weights were found at densities of 10, 12, and 14 birds m?2, in addition to a higher feed intake at densities of 10 and 12 birds m?2. Weight gain was better at a density of 10 birds m?2, showing no differences from densities of 12 and 14 birds m?2. In the period from 1 to 21 days, live weight and weight gain were higher at densities of 10, 12, and 14 birds m?2. The highest feed intake was observed at a density of 10 birds m?2, which showed no difference from the density of 14 birds m?2. A difference (P < 0.05) was observed for live weight, weight gain, and feed intake of animals reared at densities of 10, 12, and 14 birds m?2 for the phases from 1 to 35 days and the total phase from 1 to 42 days of bird age when compared to 16 birds m?2, which presented lower performance. However, feed conversion of 1-7, 1-14, 1-21, 1-35, and 1-42 days and carcass and cut characteristics showed no significant differences for all treatments. On the other hand, productivity was higher in the treatments with 14 and 16 birds m?2, but without difference between each other. No interaction (P > 0.05) was observed between stocking density and age for the assessed bone parameters. Similarly, no difference (P > 0.05) was observed for bone development of broiler chickens reared at different stocking densities for the studied parameters. Thus, the increased density of 10 or 12 birds m?2 to 14 birds m?2 has no influence on zootechnical performance, carcass and cut yields, and bone development, but increases broiler chicken productivity reared in a conventional shed without air conditioning.

This study was carried out to evaluate the growth performance and carcass characteristics of finisher broiler chickens fed diet containing cooked cocoyam tubermeal as energy source in place of maize. The proximate composition of cooked cocoyam tubermeal showed that it contained 13.11% moisture, 2.60% ash, 3.90% crude protein, 9.45% crude fiber, 1.85% ether extract and 70.13% NFE. In the finisher feeding trial, the cooked cocoyam tubermeal was used to replace maize at levels of 25%, 50%, 75% and 100% respectively in the control diet. Each finisher diet was fed to a group of 30 finisher broiler chicken for 4 weeks using completely randomized design. Each treatment was divided into 3 replicates of 10 broiler chicks each. The birds were kept on deep litter and were given feed and water ad-libitum. Parameters measured include ifinal body weight, body weight gain feed intake, feed conversion ratio, carcass characteristics and economics of production. In the finisher feeding trial, the feed intake of the finisher broilers on diets 2, 3 and 4 were similar and compared favourably with those on the control diet. The finisher group on 100% CCYM (diet 5) recorded the lowest feed intake possibly because of the dustiness of the feed. The body weight gain of the finisher broilers on diet 2 (25%) cooked cocoyam tubermeal compared favourably with the control group and was significantly (P<0.05) higher than those on other diets. It appeared that the finisher broilers could not tolerate high levels of cooked cocoyam meal due to dustiness of the feed and its anti-nutritional factors. The cost of production per kg finisher broilers was cheapest for diet 5(100% CCYM) (N356.72) and the costliest was for diet 3(50% CCYM) (N588.28). The internal organs expressed as percent of the live weight were not affected by the treatments. In terms of carcass characteristics, the finisher broilers on diet 2(25% CCYM) recorded the highest breast muscle which was significantly different (P<0.05) from other groups. There were no significant different (P>0.05) on percent back cut, drumstick, head, shank, thigh, neck and wings of the finisher broilers on all the treatments. There were no significant differences (P > 0.05) in percent dressed weight of the finisher broilers on cooked cocoyam based diets. The results of the trial have shown that cooking cocoyam corms (Xanthosoma sagittifolium) for 30 minutes was effective for reducing the cyanide oxalate, tannin, phytic acid and saponin content and that cooking did not affect the proximate composition of tannia. Cooked cocoyam tubermeal could be used to replace maize up to 25% in the diet of finisher broiler chicken without affecting body weight gain, feed intake and feed conversion ratio as indicated in this study.

Aiming to evaluate the effect of tomato waste inclusion on productive performance and characteristics of carcass and main broiler chicken cuts, an experiment was carried out using 300 male Cobb chicks, distributed in a complete randomized design, with five rations and five replicates. Diets consisted of control ration based on corn and soybean meal and four rations with 5, 10, 15 and 20% of tomato waste. Feed intake, weight gain and feed conversion and, at the end of experiment, slaughter weight, gutted carcass without feet and head, breast, drumstick, thigh, wing, back, edible guts and belly fat were evaluated every week, as well as it was the yield. Tomato waste increased feed intake in the periods from 1 to 7, 8 to 14 and 29 to 36 days of age and worsened gain weight and feed conversion of broiler chickens up to 29 days of age. Regarding carcass weight (g) and weight of the noble parts, breast, drumstick and thighs decreased linearly in function of the use of tomato waste in poultry on pre- initial and initial phase, that is, up to 28 days old, but yield (%) was not affected except for yield of heart and liver. Use of tomato waste in ration of broiler chickens during the period from 1 to 28 days may decrease weight gain and worsen food conversion. Tomato waste may be used as ration ingredient in ration of broiler chicken in the breeding period from 29 to 42 days of age up to the level of 20% without harming weight gain and feed conversion of poultry.

One method of reducing feed cost is to restrict the feed in the early life of broilers. In this regard, Fontana et al. (1992) reported that early feed restriction programs in their experiments proportionally reduced the consumption of the starter diets by an average of 22% in restricted broilers when compared with controls. Energy restriction has also been shown to result in a reduction in metabolic energy loss leading to a reduced requirement for maintenance. If during refeeding, this low requirement is maintained and if growth resumed at a normal or above normal rate (compensatory growth), feed efficiency would be substantially improved, leading to an economical advantage. This experiment was conducted to determine the effect of severity of diet dilution (energy and protein) and duration of early feed restriction on feed intake (FI), body weight gain (BWG) and feed conversion ratio (FCR) of male broiler chickens.

Low protein intake and rapid human population growth in addition constitute a major problem facing developing countries. To solve this problem of lack of adequate intake of animal products and to increase the output by majority of Nigerians, there is the need to improve poultry and poultry products production by putting a lot of effort in the production of highly reproductive animals becomes very important. The aim of this work is to compare the performance of four breeds of broiler chickens fed a popular commercial Diet in Kuta. One hundred and twenty, day-old chicks of different breeds, and thirty each (Arbor acre, Marshal, Anak, Cobb) were selected and randomly allotted to four treatments with three replicates each in a completely randomized experimental design. Result from the experiment revealed that there was no significance (P< 0.05) difference among the treatments in terms of water intake, feed intake body weight gain and feed conversion efficiency. Anak and Cobb breeds has the highest numerical values for the most of the performance indices measured such as average weekly feed intake (1425.60g, 1272.60g), total feed intake (4714.3g, 4509.8g), average weekly water intake (4046.40ml, 4317.00ml), total water intake (12698.7ml, 14527.6ml), average weekly body weight gain (298.51g, 348.13g), and feed conversion ratio (4.87, 3.67). This research show that the Cobb breed have superior performance compare to other breeds on the same feed and under same environmental condition in Kuta. This implies that the production of the four mentioned breeds can perform in Kuta but the feed is more favourable to Cobb breed.

The objective of this study was to evaluate the effects of feed supplementation with two prebiotic herbs—Origanum vulgare and Zingiber officinale—on growth performance of broiler chickens. The feed conversion ratio was determined weekly by dividing feed intake by body weight gain. A total of 400 one-day-old broiler chicks were divided into four treatment groups of four replicates of 25 chickens each using a complete design random. The four treatment groups were T0 (control), T1 (0.5% oregano), T2 (0.5% ginger), T3 (0.25% oregano + 0.25% ginger). The chicks were grown to 42 days of age. Weight gain, feed intake, conversion, carcass quality and mortality were determined weekly. Data analysis revealed that during the first 35 days of broiler chicken’s life, none of the dietary interventions had any effect on productive parameters (P > 0.05). However, during the last week of treatment, the oregano and ginger supplementation had a positive effect on weight gain and feed conversion (P < 0.05) than in the control group. In conclusion, the addition of oregano and ginger in the daily food ratio for broiler chickens during the last stage of the productive cycle improved the productive parameters, and carcass characteristics.

In this paper, we present a study on the evaluation of the effect of xylanase addition to a diet with an increasing content of modern hybrid rye (Brasetto variety) on the performance indices and viscosity of small intestine content in broiler chickens. A total of 560 1-day-old male Ross 308 chickens were randomly assigned to 1 of 10 treatments, each comprising 7 replicate cages, with 8 male birds per cage. A 5 × 2 factorial arrangement was employed, with five dietary levels of ground rye (0%, 5%, 10%, 15%, and 20%). All the diets were either unsupplemented or supplemented with xylanase (200 mg/kg of feed; with minimum xylanase activity 1000 FXU/g). In the starter rearing period (1–21 days of age), the inclusion of rye (without xylanase supplementation) to the diet, even at the lowest dietary level (5%), negatively affected body weight gain (p < 0.05); there was no effect on feed intake and feed conversion ratio. In older chickens (the grower-finisher rearing period; 22–42 days of age), none of the dietary levels of rye (5–20%) affected growth performance indices. Similarly, no significant effect of increasing dietary level of rye was found for the entire rearing period (1–42 days of age). Diet supplementation with xylanase improved body weight gain and feed conversion ratio in chickens from 1 to 21 days of age. No positive effect of enzyme was found in older birds. No significant effects of the experimental factors used were noticed on the results of slaughter analysis, i.e., the carcass yield, breast meat yield, abdominal fat, and relative weight of the liver and gizzard. A high dietary concentration of rye (20%) increased the viscosity of small intestine content (p < 0.05); however, diet supplementation with xylanase significantly alleviated this effect. The findings of this experiment indicated that modern hybrid rye grain may be used at a 20% dietary level in broiler diets during the second feeding phase, i.e., from 22 to 42 days of age, without any detrimental influence on growth performance indices, while enzyme (xylanase) positively affected body weight gain and feed conversion ratio in younger chicks (1–21 days of age).
