In order to examine the interactive effects of strontium and cholecalciferol in broiler nutrition a total of 288 male broiler chickens were fed over 28 days, eight different diets with six replicates comprising of two levels of vitamin D (5000 and 10 000 IU/kg) and four levels of strontium (0, 400, 800 and 1200 mg/kg) provided as strontium carbonate. Vitamin D and strontium produced a significant interaction on growth and feed efficiency with the addition of higher levels of vitamin D ameliorating the negative effects of strontium at 1200 mg/kg. The higher level of vitamin D also improved bodyweight gain (P < 0.05), had no effect on tibia bone composition but reduced calcium, phosphorus, potassium and magnesium retention (P < 0.05). Strontium supplementation produced no advantage to chicken performance but changed tibia bone composition. It was found that calcium and sodium maintained a ratio of ~30 : 1 in tibia bone. Vitamin D and strontium produced a significant physiological interaction and further research is required to elucidate optimum levels of supplementation for commercial broiler chicken production.

Abstract Phytogenies have been widely used as alternative feed additives to replace antibiotics in animal production. The present study aims to evaluate inclusion of S. cumini extract as feed additives on performance and haematological parameters of commercial broiler chickens. A total of 100-day-old commercial chickens (mixed sex) were randomly allocated to four treatments with five replicates. Each treatment was administrated different level of S. cumini extract in the drinking water (P0=control, P1=0.25 g/l drinking water, P2=0.50 g/l drinking water and P3=1.0 g/l drinking water). Commercial diet was provided during experiment based on nutrition requirement for starter and grower. Water and feed were given ad libitum. Data were collected to measure broiler performances and haematological parameters. One way ANOVA was applied in this study and significantly different among treatments were stated (P≥0.05). The results indicated that inclusion of S.cumini extract as feed additives in drinking water did not significantly affected (P>0.05) on animal performances and haematological parameters of commercial broiler chickens. Therefore, it concluded that S.cumini extract can be applied as alternative feed additive due to no negative effects of the S.cumini iextract on performances and haematological parameters.

Four experiments were carried out to ascertain the nutritive value and quality of oat groats (OG) as a partial replacement for corn and total replacement for wheat in practical diets for broiler chicken using one commercial broiler genotype, Cobb. In each of experiments 1 and 2, 360 day-old chicks of each sex were housed in Petersime batteries and fed starter (1–21 days) and finisher (23–42 days) diets containing 0, 200 and 400 g of Eastern (E) OG or Western (W) OG/kg. In each of experiments 3 and 4, 320 day-old chicks of each sex were housed in eight floor pens and fed starter diets containing 0, 400 and 600 g EOG/kg and finisher diets containing 0, 400, 600 and 800 g EOG/kg. Feeding up to 600 g/kg OG in starter diets and 800 g/kg in finisher diets had no significant adverse effect on biological performance or monetary returns.

Nutritional value of dietary raw bambara nut offal fortified with enzyme (Natuzyme ) on the performance of broiler chickens were investigated. Two hundred and fourty (240), unsexed one day-old commercial broiler chicks (Marshal Strain) were randomly divided into eight groups of 30 birds each. The groups were randomly assigned to eight iso-caloric and iso-nitrogenous diets in a 2 × 4 factorial arrangement involving four levels (0, 10, 20 and 30 %) of raw bambara nut offal and 2 enzyme levels (0 and 0.025 %). Each treatment was replicated three times with ten birds per replicate. There were significant differences (P < 0.05) among treatments in AFW, ADWG, ADFI, FCR and PER. Chickens fed 10 % BGO without ® Natuzyme had higher (P < 0.05) FBW, ADWG and ADFI than chickens fed 0, 20 and 30% BGO diets. Least (P<0.05) ADFI and better FCR was recorded on broiler chickens fed control diet and 20 % BGO with enzyme. respectively. Addition of enzyme improved (P < 0.05) AFW and ADWG at 20 and 30 % BGO level. Significantly (P<0.05) higher AFW, ADWG and ADFI revealed that inclusion level of BGO at 10 % did not pose any deleterious effects on the birds. There were significant (P < 0.05) differences among treatments in the digestibility of dry matter (DM), crude protein, crude fibre (CF), ether extract (EE) and nitrogen-free extract (NFE). There was no interaction (P>0.05) between enzyme and BGO across the dietary treatments. Significant (P < 0.05) differences were observed in all the blood profile parameters observed across the dietary treatments except eiosinophil concentration. It was concluded that up to 30 % BGO can be included in enzyme supplemented broiler finisher diet without adverse effects on the performance, nutrients digestibility and blood profile of broiler finisher chickens

Background: The productivity and profitability of commercial broiler largely depend on nutrition and growth performance and, therefore, this industry requires high quality protein sources, such as Corn Gluten meal (CGM). Many studies have been conducted on protein quality changes and other nutritional characteristics of CGM in several countries Corn gluten meal contains around 60% CP and is a byproduct of wet milling of corn, most of which is used for manufacture of high fructose corn syrup and corn flour. Being high in crude protein, it is often compared to animal protein ingredients during feed formulation. Thus, this study was intended to evaluate the effect of feeding corn gluten meal in feed ration on growth performance of commercial broiler chicken. Methods: A feeding trial was conducted in the year 2018 with an objective to assess the effect of feeding corn gluten meals (CGM) in broiler chicken. Six hundred broiler chickens (day old) were randomly allotted to three groups, comprising of fifty broiler chickens in each treatment group with four replicates. The group-I (T1) Broiler chicken were fed with composite diet containing 5% Corn Gluten meal where as Group-II (T2) received composite diets comprising of CGM 10%. The Group-III (T3) served as control group with normal broiler diet. The experimental period lasted for six weeks. Weekly body weight and feed consumption were measured in each group. Result: Diet composite of 10% of corn gluten meal had significantly (P≤0.05) higher weight gain, lower feed intake and improved FCR than T1 and T3 group. CGM supplementation can be ideally improved broiler weight gain, feed consumption and FCR.

Free available chlorine (FAC) concentrations in drinking water supplied to broiler chickens grown commercially in New Zealand were monitored for 11 farms in two companies. Different sites within a growout house were examined at different times of the day to determine spatial and temporal differences in FAC concentrations. Taps provided water with significantly higher FAC concentrations than did drinkers. There were no significant differences between the concentrations of FAC taken from various drinkers around the growout house. There were differences in the variations of measurements taken from the same drinker within a growout house at different times of the day, with variations increasing in the afternoon. No growout houses provided an average FAC content of 2 ppm, the suggested standard in one company. Three growout houses consistently met the chlorine concentration of 0.2 ppm suggested by the New Zealand Drinking Water Standards.

Chicken Farmers of Canada has been progressively phasing out prophylactic use of antibiotics in broiler chicken production. Consequently, hatcheries, veterinarians, and nutritionists have been mandated to contend with less reliance on use of preventive antibiotics. A topical concern is the increased risk of proliferation of enteric pathogens leading to poor performance, increased mortality and compromised welfare. Moreover, the gut harbors several taxa such as Campylobacter and Salmonella capable of causing significant illnesses in humans via contaminated poultry products. This has created opportunity for research and development of dietary strategies designed to modulate gastrointestinal environment for enhanced performance and food safety. Albeit with inconsistent responses, literature data suggests that dietary strategies such as feed enzymes, probiotics/prebiotics and phytogenic feed additives can bolster gut health and function in broiler chickens. However, much of the efficacy data was generated at controlled research settings that vary significantly with the complex commercial broiler production operations due to variation in dietary, health and environmental conditions. This review will summarize implications of mandated restrictions on the preventative use of antibiotics and emerging Canadian broiler production programs to meet processor specifications. Challenges and opportunities for integrating alternative dietary strategies in commercial broiler production settings will be highlighted.

In this work, antimicrobial usage data from 2,546 commercial broiler chicken flocks originating from 37 farms are presented. Antimicrobial usage data at the flock level were based on mandatory documentation of antibiotic treatments in livestock in Germany, collected retrospectively for the time period of 2013–2018. The data encompasses all antimicrobial treatments during the fattening period of each flock, starting with the placement of day-old chicks at the barn. The aim of this analysis was to investigate antibiotic usage patterns in broiler chicken flocks in Germany, temporal trends in treatment frequency, the proportions of different antimicrobial classes and the weights of the broiler chickens at the time of treatment. The median treatment frequency over all flocks was six, and veterinary medicinal products belonging to nine different antimicrobial classes were used. Overall, the most frequently used classes were aminoglycosides (25.6%) and lincosamides (25.6%), followed by polypeptides (21.4%) and beta-lactams (16.2%). Over the 6 years evaluated, a considerable increase in the relative usage of lincosamides and aminoglycosides was observed. Compared to the first year of data collection, the percentage of treatments with fluoroquinolones, macrolides and polypeptides decreased in consecutive years. The median age of the broiler chickens at the time of treatment was 5 days, which corresponded to a median body weight at the time of treatment of 111 g, with substantial differences among various antimicrobial classes. We showed that in Germany, the median weight of broiler chickens at the time of treatment was substantially lower than the standard weight of broilers of 1,000 g proposed by the European Surveillance of Veterinary Antimicrobial Consumption. The median weight at treatment is very much influenced by the frequency of age-specific diseases. As different antimicrobial classes are used to combat these diseases, variations in the weight at treatment may have a considerable impact on the estimated treatment indicators. Additionally, a decrease in the relative usage of the highest-priority critically important antimicrobials, such as fluoroquinolones, macrolides and polypeptides, was shown, which might be the consequence of increasing awareness of the antibiotic resistance situation as well as of antibiotic monitoring and benchmarking systems currently running in Germany.

O controle da umidade da cama na criação comercial de aves é essencial, especialmente no verão, quando há maior ingestão de água pelas aves e as fezes ficam muito liqüefeitas. Uma solução é incorporar substâncias adsorventes de água na dieta, como aluminossilicato, que reduz a água livre e proporciona menor umidade na cama. Este estudo teve por objetivo avaliar se o aluminossilicato pode melhorar o aspecto das fezes ao ser adicionado na ração de frangos. Foi realizado numa granja comercial em São José dos Pinhais-PR, utilizando-se dois tratamentos e quatro repetições com 25 aves cada. No primeiro tratamento adicionou-se 1% de aluminossilicato (SilvetÒ) à dieta, no segundo, o produto estava ausente. Dos 3 aos 40 dias de vida as aves receberam ração e água ad libitum, sendo pesadas aos 22 e 40 dias e avaliadas quanto consumo de ração, ganho de peso e conversão alimentar. Realizou-se também necropsia de 4 aves por tratamento, para observação de possíveis lesões macroscópicas e colheita dos conteúdos intestinais que foram enviados para análise de umidade total e cinzas. Os resultados foram submetidos a ANOVA, não havendo diferenças significativas quanto ao desempenho das aves entre os tratamentos, entretanto, em ambas as idades as porcentagens de cinzas e umidade total foram maiores nas aves que receberam aluminossilicato. A inclusão do aluminossilicato na dieta não influencia no desempenho das aves, porém melhora o aspecto fecal, aumentando a quantidade de matéria seca e reduzindo a umidade livre nas fezes excretadas. The use of aluminossilicate (silvet®) as an adjuvant in broiler feces aspect and performance improvement Abstract The control of bed humidity in the creations of r commercial broiler chicken is essential, especially in the summer, when there is a larger ingestion of water the feces becoming more liquefied. The incorporation of water adsorptive substances to the diet, such as the aluminossilicate, reduces the free water and provides lower humidity in the bed. This study was carried out to evaluate the use of aluminossilicate on feces aspect. Two treatments and four repetitions with 25 chicks each were performed in a commercial farm in São José dos Pinhais-PR. At the first treatment 1% of aluminossilicate was added (SilvetÒ) to the diet, while the product was absent in the other. From 3 to 40 days of life the chicks received ration and water ad libitum and were weighted at days 22 and 40 and evaluated over ration consumption, bodyweight gain and alimentary conversion. Necropsy of 4 chicks per treatment was carried out in order to detect possible macroscopic lesions, collect intestinal contents and analyze total humidity and ashes content in the feces. The results submitted to the statistical method ANOVA, did not show expressive differences between the treatments for animal performance. However, in both ages the total humidity and ash percentage were higher on broiler that received aluminossilicate. Aluminossilicate inclusion on diet did not influence in the broiler performance, although it improved the feces aspect by increasing the drought matter quantity and reducing the feces free humidity.

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.
