Metabolisable Energy

A completely randomised design study with a 3 × 2 factorial arrangement was conducted. A total of 480 male broiler chickens were used to determine the influence of phytase addition, plant protein source [soybean meal, soybean meal + 200 g/kg of blue lupin meal (Lupinus angustifolius L.) or soybean meal + 200 g/kg yellow lupin meal (Lupinus luteus L.)] on performance of broiler chickens, ileal calcium (Ca), phosphorus (P) and protein digestibility, tibia bone characteristics and nitrogen-corrected apparent metabolisable energy. All diets were deficient in Ca, available P as well as lysine and total sulfur amino acids. Birds fed different protein sources were characterised by similar bodyweight gain and feed intake during the whole trial but feed conversion ratio was higher when birds were fed supplemented with yellow lupin meal (P < 0.05). Phytase improved bodyweight gain and feed conversion ratio regardless of protein source (P < 0.05). Diets supplemented with 200 g/kg blue or yellow lupin meal were found to be lower in nitrogen-corrected apparent metabolisable energy than soybean meal diets (P < 0.05). Birds fed diets supplemented with phytase were characterised by higher utilisation of Ca and P than birds whose feed was not supplemented with phytase (P < 0.05). Tibia bone ash as well as Ca content was similar across protein sources (P > 0.05), whereas tibia P content was lower when soybean meal or blue lupin meal was used (P < 0.05). Birds fed diets supplemented with blue lupin meal were characterised by the highest tibia P content (P < 0.05). Birds fed phytase-supplemented diets were characterised by higher tibia Ca and P content irrespective of protein source.

Two experiments were conducted to examine the nutritive value of yellow lupins for weaner pigs. Using a completely randomised block design, Experiment 1 was conducted to determine the optimum inclusion level for yellow lupins (cv. Wodjil) in the diet of weaner pigs (6.14 kg ± 0.278). Experiment 2 was conducted using a 2 × 2 factorial design to examine whether supplementation of an enzyme preparation (VegPro) either in a soybean meal-based diet (0 g/kg yellow lupins) or in a yellow lupin-based diet (150 g/kg) improved performance of piglets (6.17 kg ± 0.317). In Experiment 1, the feed conversion ratio significantly increased at week 1 (linear effect, P = 0.040) and at week 3 (quadratic effect, P = 0.010) as the concentration of yellow lupins increased in the diet. In Experiment 2, supplementation with the enzyme preparation improved the feed conversion ratio in the pigs fed the lupin-based diet only but not in the pigs fed the soybean meal-based diet in week 2 (interaction P = 0.001). The results indicate that the optimum inclusion levels of yellow lupins for piglets immediately after weaning was 150 g/kg, and supplementation of a multi-enzyme preparation to a yellow lupin-based diet for the weaner pigs improved performance relative to the soybean meal-based diet.

The study was conducted to investigate the potent capacity of selenium to curtail the adverse  effects of heat stress in broiler chickens. A total of 256, day old Cobb 500 broiler chicks were  randomly allotted to four experimental treatments (0, 0.1, 0.2 and 0.3 mgSe/kg), with four  replicates in a completely randomized design. Initial weight, daily feed intake, daily weight  gain, final weight, feed conversion ratio, daily water intake, feed cost/kg gain, mortality,  serum cortisol and thyroxine levels, calcium, phosphorus and ash levels in tibia bone and  faeces and weight, length and robusticity index of tibia bone were determined. Results  indicated that Initial weight, daily feed intake, daily weight gain, final weight, feed  conversion ratio, daily water intake and mortality were similar (p>0.05) across the treatment  groups and feed cost/kg gain was lower in broilers birds fed 0.3 mgSe/kg. Selenium  supplementation at 0.1 and 0.2 mgSe/kg lowered (p<0.05) cortisol and increased (p>0.05)  thyroxine level, respectively. Mineral deposition in tibia bone was similar (p>0.05), calcium  excretion was higher (p<0.05) in the control group and higher phosphorus was observed in  the faeces of broilers fed the control diet, 0.1 and 0.3 mgSe/kg. Tibia measurements were  similar (p>0.05) in all treatments.     L'étude a été menée pour étudier la puissante capacité du sélénium à réduire les effets  néfastes du stress thermique chez les poulets de chair. Un total de 256 poussins de poulets  Cobb 500 âgés d'un jour ont été attribués au hasard à quatre traitements expérimentaux (0,  0.1, 0.2 et 0.3 mgSe / kg), avec quatre réplicats dans un plan complètement randomisé. Poids  initial, apport alimentaire quotidien, gain de poids quotidien, poids final, taux de conversion  alimentaire, apport quotidien en eau, coût de l'aliment / gain de kg, mortalité, taux de cortisol  et de thyroxine sériques, taux de calcium, de phosphore et de cendres dans les os et les fèces  du tibia et poids, la longueur et l'indice de robustesse de l'os du tibia ont été déterminés. Les  résultats ont indiqué que le poids initial, l'apport alimentaire quotidien, le gain de poids  quotidien, le poids final, le ratio de conversion alimentaire, l'apport quotidien en eau et la  mortalité étaient similaires (p> 0.05) dans les groupes de traitement et le coût de  l'alimentation / gain en kg était plus faible chez les poulets de chair nourris 0.3 mgSe / kg. Une  supplémentation en sélénium à 0.1 et 0.2 mgSe / kg a abaissé (p <0.05) le cortisol et augmenté  (p> 0.05) le taux de thyroxine, respectivement. Les dépôts de minéraux dans l'os du tibia  étaient similaires (p> 0.05), l'excrétion de calcium était plus élevée (p <0.05) dans le groupe  témoin et une plus grande quantité de phosphore a été observée dans les fèces des poulets de

We evaluated the influence of enzymatic supplementation on the growth performance and cecal microbiota of broilers. A total of 2160 1-day-old male chicks were used in a 3 × 2 × 2 factorial arrangement (three corn hybrids, two drying temperatures −80 and 110 °C, with or without the inclusion of an enzymatic blend (amylase, xylanase, and protease) (20 birds/pen, n = 9). For all performance and digestibility parameters, we observed, in general, isolated effects of the corn hybrids and drying temperature. Birds that received the enzymatic blend in the diet showed better weight gain from 1 to 21 days (d) and better digestibility coefficients of nutrients at 42 d. Birds fed diets with corn dried at 80 °C showed a better feed conversion ratio from 1 to 42 d. At 21 d of age, enzymatic supplementation had positive effects on jejunum morphology. Enzyme supplementation increased the abundance of the phylum Tenericutes, class Bacilli and Mollicutes, reduced Clostridia, and increased the abundances of the families Lactobacillaceae, Anaeroplasmataceae, and O_RF39;F. In conclusion, the addition of amylase, xylanase, and protease led to a better nutrient digestibility, performance, and intestinal morphology. In addition, enzyme supplementation changed the diversity, composition, and predicted function of the cecal microbiota at d 21.

The effects of wet feeding and a multi-enzyme preparation on the nutritional value of wheat screenings (WS) for broiler chicks were investigated. In total, 540 1-day-old Ross-308 broiler chicks were fed a corn–soybean meal-based diet up to 29 days of age. At that time, the birds were randomly assigned to nine diets in a completely randomised design with a 3 × 3 factorial arrangement, including three levels of WS (0%, 25% and 50%, WS0, WS25 and WS50 respectively) and three processing methods (no processing, enzyme supplementation and wet feeding). The enzyme mixture contained endo-1, 4-β-xylanase (200 FXU/g), endo-1, 4-β-glucanase (50 FBG/g), endo-1, 8-β-glucanase (21 FBG/g), hemicellulase (3000 VHCU/g), α-galactosidase (3 GALU/g) and protease (260 U/g) and was supplemented at a level of 6 g/kg of diet. The inclusion of water in wet diets was in the extent of 1.2 kg/kg of diet. During the period from 29 to 49 days of age, feed intake was not affected (P > 0.05) by the inclusion of WS in the diet, whereas chicks fed the WS25 diet had a higher (P < 0.05) bodyweight gain than did those on WS0 diet. The feed conversion ratio (FCR) was improved (P < 0.05) by the inclusion of WS in the diet throughout the study. The feed intake was increased (P < 0.05) by enzyme supplementation to WS50 diet, while bodyweight gain was increased (P < 0.05) by wet feeding. Enzyme supplementation did not affect (P > 0.05) FCR, whereas wet feeding resulted in lower (P < 0.05) FCR over the entire study. The plasma concentration of glucose was increased (P < 0.05) by the inclusion of WS in the diet. The viscosity of the ileal digesta was higher (P < 0.05) in chicks receiving the WS50 diet than that in chicks receiving the other diets. The jejunal villus height was increased (P < 0.05) and the jejunal crypt depth was decreased (P < 0.05) by the inclusion of WS in diet. The jejunal crypt depth was greater (P < 0.05) in chicks receiving the wet diets than in chicks receiving the enzyme-supplemented diets (P > 0.05). In conclusion, the results from the present study indicated that broiler growth performance was improved by the inclusion of WS in the diet and also by wet feeding. These effects were largely compatible with the changes that occurred in the small intestine morphology, but not with those observed for ileal digesta viscosity.

Broiler Breeder

One of the comestibles that have high nutritional value and are easy to obtain is chicken. The higher demand for chicken must be accompanied by an increase in production. It is important for the breeder of broiler chicken to choose high quality Day Old Chick (DOC) from the broiler breeder which also has high quality and productivity. The type of broiler breeder that is grown in PT. Karya Indah Pertiwi is Ross 308. Observations were made when the chickens were 18th to 21st weeks old in 6 henneries totaling about 10,000 chickens. The performance of broiler breeder observed were feed consumption, bodyweight gain, feed conversion ratio, and uniformity. Feed consumption of broiler breeder at 18th to 21st week was 659.4 g/chicken, 700,583 g/chicken, 742,116 g/chicken, 767.2 g/chicken. Bodyweight gain at 18th to 21st week was 143.51 g/chicken, 193.3 g/chicken, 63.43 g/chicken, 167.96 g/chicken. Feed conversion ratio at 18th to 21st week was 4.5, 3.6, 11.6, 4.5. The uniformity at 18th to 21st week was 77%, 81%, 81%, 81%. In conclusion, the value of feed consumption for broiler breeder at PT. Karya Indah Pertiwi was increasing every week. Bodyweight gain at 20th week was lower than 18th, 19th, and 21st week. The value of feed conversion ratio at 20th week was higher than at 18th, 19th, and 21st week. Chicken uniformity value at 18th week was not good it was at 77%, while at the 19th, 20th, and 21st week it was quite good at 81%.

Abstract An experiment was conducted on 240 one-day old male (Ross308) chicken to the effect of substitution of dried mealworm (Tenebrio molitor) with soybean meal on growth performance and carcass characteristics broiler chicks. Chicks fed in a completely randomized design with 4 replicate cages (12 birds per cage). Five dietary treatments used: 1- Control treatment: Basal diet based on corn-soybean meal without adding dried mealworm, 2- Replacement of 5% dried mealworm with soybean meal in the base diet, 3- Replacement of 10% dried mealworm with soybean meal in the base diet, 4- Replacement of 15% dried mealworm with soybean meal in the base diet and 5- Replacement of 20% dried mealworm with soybean meal in the base diet. The results of the experiment showed that 3rd and 4th treatments with a substitution of 10 and 15 percent showed a higher mean weight gain and a daily gain, but their feed intake was lower comparing other treatments, and finally, the feed conversion ratio showed a significant decrease with respect to control treatment using these replacement levels. At 21 and 42 days of age, carcass yield and relative weight of the breasts showed significant increases in treatments 3 and 4, and other characteristics of chicken carcasses were not affected by the test treatments. The experiment showed that replacing soybean meal with 10% and 15% worm powder significantly improved the performance of broiler chickens, but no significant difference was found between the two levels.

This study aimed to evaluate the influence of the substitution of soybean meal (SM) by detoxified castor cake (DCC) by two alkaline products on intake, performance and on the growth curve of goat’s kids. 24 were used, Saanen goats (n=12) and Anglo Nubian (n=12), with initial body weight of 16.2±0.67 kg, initial age of 3 months and confined during the growth phase. The treatments consisted of three diets: a standard diet formulated with a traditional protein source, the soybean meal (SM); and test diets, which consisted of a protein source alternative, differing detoxification processes, on the basis of calcium hydroxide (Ca(OH)2) or sodium hydroxide (NaOH). The animals were distributed in a completely randomized design, in factorial 3 x 2 (diet SM, Ca(OH)2 DCC and NaOH DCC x Saanen and Anglo Nubian) totaling six sessions with four replicates each. The experimental period lasted 270 days. The non-linear models used were the Gompertz and Logistic. There was no effect (P < 0.05) of diets on the intake of nutrients, but there was no effect (P > 0.05) of breeds and interaction between both factors. The intake of DM during the phase of growth was greater for the goats fed with SM. There was no effect (P>0.05) of diets nor of the breeds in the ADG. Feed conversion was influenced (P < 0.05) by the diets, in which the goats fed diets with DCC presented better feed conversion. It has been observed that both models had good adjustments, with values numerically superior to 90%, however, the logistic model showed higher R2 and, at the same time, asymptotic index (AI). Despite the ADG be equal, the breeds presented absolute growth rate (AGR) vary over time, where the Saanen goats reached the peak first (181 days), with AGR of 0.14 kg day-1. However, even the goats Anglo Nubian reaching the highest peak late, the AGR was higher, around 0.16 kg day-1 higher than the Saanen. Both castor cake has the potential to replace the SM on a diet of goat’s kids during the growth phase. The mathematical model of Logistics estimates more accurately the growth of Saanen goats and Anglo Nubian, being that the rate of absolute growth is greatest in goats Anglo Nubian.

Two experiments were conducted to study the effects of either soluble or insoluble fibre naturally occurring in wheat and oats, on technical pellet quality and nutritional value for broiler chickens. In exp. 1, the effects of insoluble fibre were studied by mixing diets based on wheat or naked oats with either coarse or fine oats hulls followed by pelleting. Hull inclusion increased (P < 0.05) starch gelatinisation, especially in the diets based on oats. Addition of finely ground oats hulls improved pellet durability, in particular after storage, while no such effect was observed for coarse oats hulls. Oats hulls inclusion caused a more elastic pellet with higher breaking resistance (P < 0.05). Lower (P < 0.05) energy consumption was observed for diets based on oats compared with wheat, while no effect of fibre inclusion on energy consumption was found. In exp. 2, the influence of pelleting on the viscosity effect of soluble fibres in diets based on wheat or oats was studied. A significant increase (P < 0.05) in intestinal viscosity of broiler chickens was observed for all batches of grain exposed to steam pelleting. Viscosity was doubled (P < 0.05) with wheat diets, while the increase in viscosity was even greater in oat diets. In wheat diets, feed intake and weight gain was reduced (P < 0.05), while feed conversion ratio was not affected. Steam pelleting of oats reduced (P < 0.05) feed intake and weight gain, and increased feed conversion ratio (P < 0.05). The improvements (P < 0.05) in metabolisable energy and dry matter digestibility in wheat diets was not consistent with the observed increases in viscosity or with the results obtained with oats.

The present study was conducted to determine the effect of silicon oxide in broiler chickens drinking water on performance and litter quality. A total of 120, one-day old mixed sex broiler chicks were randomly divided into 4 treatments and 3 replications, with 10 birds in each replicate in a completely randomised experimental design, with 4 silicon levels (0.00, 1.50, 2.00 and 2.50 mg of silicon oxide/litre of water. Corn-soya based diets were formulated at the starter (0–4 weeks) and finisher (5–8weeks) phases and were supplied ad libitum with free access to water. The average daily temperature and relative humidity inside the poultry house were 35.9 °C and 36%, respectively. At the starter phase, chicks administered 2.00mg silicon oxide/litre of water had significantly (p<0.05) higher final body weight (991.00g) and average weight gain (950.96g) compared to chicks without silicon oxide 778.57 g and 738.54g. The inclusion of 2.00 mg silicon oxide/litre of water improved feed conversion ratio compared to the control group (p < 0.05) and significantly reduced feed cost per kg gain. For the finisher phase, chickens administered 2.00mg silicon oxide/litre of water had the best results for final weight, weight gain and feed cost per kg gain. Also, inclusion of silicon oxide in broiler chickens water improved litter quality as predominantly dry material but with some areas of wet shavings was observed. In conclusion, silicon oxide in broiler chickens drinking water at 2.00mg/litre of water enhanced growth performance, improved feed conversion ratio and litter quality as well as reduced feed cost per kg gain at the starter and finisher phases respectively.
