Two experiments were conducted to investigate the effects of supplementing broiler diets fed to 6 wk of age, with 0, 10, 20 or 30% of commercially heated unextracted soybeans (T.I.A. 3.9 mg g−1). Birds fed soybeans consumed less feed in the 0- to 21-d starter period and this was associated with reduced weight gain (P < 0.05) and increased feed intake: weight gain (P < 0.05). There was a decrease in calcium, phosphorus, magnesium and fat retention with feeding of soybeans and this effect was most pronounced with the 30% inclusion level. Diet ME was also reduced with increased use of soybeans (P < 0.05). However, there was a decrease in digesta and fecal soap concentration with an increase in dietary levels of heated ground soybeans (P < 0.01). While carcass weight followed a trend similar to that of weight gain (P < 0.01), there was no difference between treatments for percent carcass yield (P < 0.05). Soft fat depot areas were observed when soybean oil was the primary dietary fat. Fatty acid analysis of carcass fat confirms a high degree of unsaturation for birds fed 30% heated soybeans. However, this feature was not unduly objectionable nor did it affect carcass grading (P > 0.05). Key words: Heated soybeans, broiler performance, carcass quality

Optimum inclusion level of boiled Mucuna cochinchinensis and its replacement value for soybean meal in both starter and finisher broiler diets were assessed using 400 unsexed 7-day-old broiler chickens in a completely randomised experiment. The boiled Mucuna meal was used to replace soybean protein at five levels (0, 19, 38, 57 and 76%) in isonitrogenous and isocaloric diets. Feeding of the experimental diets lasted 4 weeks in each of the starter and finisher phases. During the last week of each phase, three birds per replicate were selected and used for metabolism (nutrient retention) studies. At the starter phase, only bodyweight and daily weight gain were significantly depressed (P < 0.05) by inclusion levels of 38% and above, whereas bodyweight, daily weight gain, feed conversion ratio and protein efficiency ratio were depressed (P < 0.05) by inclusion levels of 57 and 76% at the finisher phase. At both phases, the inclusion level had a cost sparing effect such that the highest inclusion level resulted in the production of the cheapest diet and lowest cost per unit weight gain. The replacement and inclusion levels produced no significant (P > 0.05) effects on the retention of all the proximate components and energy at both starter and finisher phases. Therefore, on the basis of bodyweight and weight gain, the replacement of soybean protein by boiled M. cochinchinensis at 19 and 38% for starter and finisher phases, respectively, is recommended. These translate to 9.36 and 14.4% inclusion levels of boiled M. cochinchinensis in starter and finisher broiler diets, respectively.

EFFECT OF SUBTITUTION OF BASIC RATIONS WITH PAPAYA LEAF MEAL ON BROILER PERFORMANCE.  This research aims to know the effect of substitution of basic rations with papaya leaf meal on broiler performance. Using 100 broiler chickens aged 2 weeks with an initial weight rate of 278.75 g. The design used was complete random design (CRD) consisting of 4 treatments and 5 replications. The arrangement of the treatment was as follows: R0 = 100% basal ration (RB) + 0% papaya leaf meal (PLM), R1 = 95% basal ration + 5% PLM, R2 = 90% basal ration + 10% PLM, R3 = 85% basal ration + 15% PLM. The results of the analysis of variance showed that the replacement of a portion of basal rations with papaya leaf meal had a significantly different (P < 0.05) on feed intake, daily weight gain and feed conversion. Based on the results of this study, It can be concluded that the using of papaya leaf meal can replace a portion of ration until 5% level.Keywords: Performance, papaya leaf meal, broiler chickens

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.

In the present study, sterilized rice bran was fermented for 48, 72 and 96 hours by Aspergillus flavus and proximate analysis indicated that fermentation changed nutritive value of the rice bran. Four experimental feeds were fed to 4 groups of day old broiler chicks for 6 weeks to evaluate their effects on broiler performance (weekly feed intake, weight gain, FCR and mortality). During first 2 weeks, birds of group D showed significant difference (P less than 0.05) in feed intake and weight gain as compared to groups A (control), B and C. All groups did not show significant differences in feed conversion ratios (FCR). During 3rd week of trial, chickens of Group D showed significant difference (P less than 0.05) in feed intake, weight gain and FCR as compared to group A. During last 3 weeks, birds in group D showed significant difference (P less than 0.05) in feed intake, weight gain and FCR as compared to birds of groups A, B and C. Group D showed significantly higher weight gain and better FCR (P less than 0.05) as compared to groups A, B and C. On the whole, broiler chickens fed on 96 hours fermented rice bran showed best growth performance. In-vivo phytase activity was determined in ash of tibia bones collected from selected birds in each group. Group D showed significantly high percentage (P less than 0.05) of ash and phosphorus in tibia bones as compared to groups A (control), B and C. In conclusion, fermented rice bran showed beneficial effect on broiler performance and could be used in poultry feed as phytase source.

Broiler chickens were fed starter diets containing 0, 250 or 500 g kg−1 naked oat and, from 29 to 40 d of age, grower diets with 0, 250, 500 or 750 g kg−1 naked oat. All diets included an enteric antibiotic and water-miscible forms of vitamins A, D, E and K. Broiler performance, as evaluated by weight gain and feed:gain ratio, was as good as or better than the corn-soy control diet with up to 500 g kg−1 naked oat in the starter diets. A starter-by-grower diet interaction showed that weight gain was independent of oat level in the grower diet of birds previously fed naked oat, but gain was impaired by higher levels of oat following an oat-free starter diet. Carcass quality improved with increasing oat level in the starter diet by a decrease in abdominal fat and a decrease in oxidation of thigh meat lipids.

Short Term

The aim of present study was to investigate the short-term and long-term effect of the peripheral administration of ghrelin on the growth performance (feed intake, weight gain, and feed conversion ratio), carcass quality, and selected serum biochemical (glucose, total cholesterol, triglyceride, and total protein) and hormonal (T3, T4, and corticostrone) indices in broiler chickens. 240 one-day-old broiler chickens were selected, and allocated into three treatment groups (control and two experimental groups). On day-21 of the rearing period, ghrelin was peripherally administrated to three experimental groups. The control group contained birds without any administration of peptide or solution, groups G50 and G100; included birds with Ip-injection of 50 and 100 (ng/100g BW) ghrelin peptide, respectively. The peripheral administration of exogenous ghrelin did not affect feed intake, body weight gain (BWG), feed conversion ratio (FCR) and carcass characteristics in broiler chickens. In short-term samples taken 12h after ghrelin infusion, the glucose level was increased in ghrelin-treated groups (162 and 151 mg/dl in G50 and G100 compared with 117 mg/dl in control; P< 0.01) and there were significant declines for TC, triglyceride, and TP in the ghrelin-treated groups (G50 and G100) compared with the control. In addition, long-term glucose level has a greater value in G50 and G100 (182 and 200.66 mg/dl) compared with control (133.60 mg/dl) group (P< 0.01). A significant decline was also observed for TC and triglyceride content in the ghrelin-treated groups (P<0.05). There was no significant difference among groups for TP in short-term and long-term samples. There was a significant increase for T4 in ghrelin-treated groups (G50 and G100) compared with the control (4.55 and 4.57 ng/ml vs 4.20 ng/ml respectively; P< 0.05) in long-term samples. In conclusion, the peripheral administration of ghrelin in broiler chickens, during the commercial rearing period did not affect the overall growth performance, carcass quality and feed conversion ratio. The infusion of exogenous ghrelin may increase the levels of serum glucose, decrease total cholesterol and triglyceride, and T4 levels are increased in the long-term (and not in the short-term or 12h after administration).

Nutrients Digestibility

A total of 144, one-day-old Arbor Acre chicks were used to investigate the effect of feeding diets containing cowpea milling waste and plantain peel meal mixture (CMWPPM) on the growth performance, nutrients digestibility and economy of feed conversion of broiler chickens. The birds were randomly allotted to four dietary treatments in a completely randomized design model, and consisted of 0, 10, 20 and 30 % dietary inclusion levels of CMWPPM. Each treatment was replicated three times with 12 chicks per replicate, making a total of 36 chicks per treatment. The experiment lasted for seven weeks. Nutrients digestibility studies were carried out at the 3rd and 7th week of the experiment using speciallydesigned metabolism cages. Results showed that at the starter phase, birds on CMWPPM 0% had significantly (P<0.05) higher feed intake, while birds on CMMPPM 20 % had significantly (P<0.05) lower feed intake than birds on the other treatments. The cost of feed and total cost of feed intake were significantly (P<0.05) higher for CMWPPM 30 % and significantly lower for CMWPPM 20 % than for the other treatments; while feed cost per kg weight gain had no significant difference across the treatments. At the finisher phase, there were no significant differences in all the growth performance parameters measured across the treatment groups. However, total cost of feed intake was significantly (P<0.05) higher for CMWPPM 10 % and significantly (P<0.05) lower for CMWPPM 20 %. The feed cost per kg weight gain was significantly (P<0.05) higher for CMWPPM 10 % and significantly (P<0.05) lower for CMWPPM 20 % and 30 % diets. Results of nutrients digestibility at the starter phase show that though dry matter, crude protein, crude fibre and nitrogen free extract digestibility were significantly (P<0.05) different across the treatments, there were no significant (P>0.05) difference in the overall total digestible nutrient across the diets. For the finisher phase, as the level of CMWPPM increased in the diets, the CP, CF, ash, lipid, NFE and TDN decreased across the treatments Therefore, it is concluded that the inclusion level of CMWPPM in the diet of broiler chickens should not exceed 20 % for optimum economy of feed conversion at the finisher phase; whereas birds can be fed diets containing 30 % dietary inclusion level of CMWPPM with good economy of feed conversion at the starter phase.   Un total de 144 poussins de 'Arbor Acre' âgés d'un jour a été utilisés pour étudier l'effet des régimes alimentaires contenant des déchets de 'cowpea' et du mélange de repas defarine d'écorce de 'plantain'. (Le 'CMWPPM') sur les performances de croissance, la digestibilité des nutriments et l'économie de la conversion alimentaire des poulets de chair. Les oiseaux ont été attribués au hasard à quatre traitements diététiques dans un modèle de conception complètement aléatoire, et consistaient en des niveaux d'inclusion alimentaire de 0, 10, 20 et 30% de 'CMWPPM'. Chaque traitement a été répété trois fois avec 12 poussins par répétition, soit un total de 36 poussins par traitement. L'expérience a duré sept semaines. Des études de digestibilité des nutriments ont été réalisées à la 3ème et 7ème semaine de l'expérience en utilisant des cages de métabolisme spécialement conçues. Les résultats ont montré qu'à la phase de démarrage, les oiseaux sous 'CMWPPM' 0% avaient une ingestion alimentaire significativement (P <0,05) plus élevée, tandis que les oiseaux sous 'CMMPPM' 20% avaient une ingestion alimentaire significativement (P <0,05) inférieure à celle des oiseaux sur les autres traitements. Le coût de l'alimentation et le coût total de la prise alimentaire étaient significativement (P <0,05) plus élevés pour CMWPPM 30% et significativement plus faibles pour CMWPPM 20% que pour les autres traitements ; tandis que le coût de l'alimentation par kg de gain de poids n'avait pas de différence significative entre les traitements. Lors de la phase de finition, il n'y avait pas de différences significatives dans tous les paramètres de performance de croissance mesurés dans les groupes de traitement. Cependant, le coût total de l'ingestion alimentaire était significativement (P <0,05) plus élevé pour CMWPPM 10% et significativement (P <0,05) inférieur pour CMWPPM 20%. Le coût de l'alimentation par kg de gain de poids était significativement (P <0,05) plus élevé pour le CMWPPM 10% et significativement (P <0,05) inférieur pour les régimes CMWPPM 20% et 30%. Les résultats de la digestibilité des nutriments à la phase de démarrage montrent que bien que la digestibilité de la matière sèche, des protéines brutes, des fibres brutes et de l'extrait sans azote soient significativement différentes (P <0,05) d'un traitement à l'autre, il n'y avait pas de différence significative (P> 0,05) dans le total de nutriments digestibles à travers les régimes. Pour la phase de finition, au fur et à mesure que le niveau de 'CMWPPM' augmentait dans les régimes alimentaires, le 'CP', les 'FC', les cendres, les lipides, l'NFE et le TDN diminuaient au fil des traitements. Par conséquent, il est conclu que le niveau d'inclusion de 'CMWPPM' dans l'alimentation des poulets de chair dépasse 20% pour une économie optimale de la conversion des aliments lors de la phase de finition ; tandis que les oiseaux peuvent être nourris avec des aliments contenant 30% de taux d'inclusion alimentaire de 'CMWPPM' avec une bonne économie de conversion alimentaire lors de la phase de démarrage.

The therapeutic use of vitamin D3 and strontium has been successful for the treatment of osteoporosis in humans; however, the value of similar strategies in poultry is not clear. Male Ross broiler chicks (n = 216) were used in a 28-day broiler trial to assess effects of vitamin D3 and strontium supplementation on performance, nutrient retention, bone composition, and bone mass. Treatments included an industry-standard control diet and five additional diets where vitamin D3 was added at 5000, 20 000, or 35 000 IU/kg and strontium was added at 0 or 1200 mg/kg in a 3 × 2 factorial design. Broiler chickens supplemented with strontium and additional vitamin D3 did not increase bodyweight; however, there was a significant improvement in feed efficiency at medium levels of vitamin D3, and although not statistically significant, there was also an improvement in feed conversion ratio with strontium supplementation at normal vitamin D3 concentrations. Strontium supplementation at normal levels of vitamin D3 significantly (P < 0.01) increased calcium, phosphorus, sodium, potassium, and magnesium retention. A high concentration of vitamin D3 produced a significant improvement in apparent metabolisable energy, protein, and dry matter utilisation in the broiler chicken. Paradoxically, however, there was a detrimental effect of high vitamin D3 on bodyweight and feed efficiency, which was partially ameliorated by strontium supplementation. Strontium addition did not change bone mass but did change bone composition. High levels of vitamin D3 significantly (P < 0.01) reduced bone ash content and increased strontium content of bone. In conclusion, both vitamin D3 and strontium have the potential to positively influence the performance, mineral retention, and bone characteristics of broiler chicks. However, as with calcium and phosphorus, vitamin D3 and strontium interact and so more research is required with strontium on the optimum dose rate and its relationship with vitamin D3, calcium, phosphorus, and IGF-1 in broiler nutrition.
