The experiment was conducted at the Ban­gabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur to study the response of chickpea (Cicer arietinum L) to dual inoculation of Rhizobium and arbuscular mycorrhiza, poultry litter, nitrogen, and phosphorus on spore population and colonization, nodulation, growth, yield attributes, and yield. The performance of Rhizobium inoculant alone was superior to control in all the parameters of the crop studied. Among the treatments dual inoculation of Rhizobium and arbuscular mycorrhiza in presence of poultry litter performed best in recording number and dry weight of nodules, dry weight of shoots and roots, number of pods/plant, number of seeds/pod, and seed yields of chickpea. The highest seed yield of 3.96g/plant was obtained by inoculating chickpea plants with dual inoculation of Rhizobium and arbuscular mycorrhiza in association with poultry litter. Treatments receiving dual inoculation of Rhizobium and arbuscular mycorrhiza in presence of nitrogen and phosphorus, Rhizobium inoculant in presence of nitrogen and phosphorus, and that of arbuscular mycorrhiza in presence of nitrogen and phosphorus were similar as that of treatment receiving dual inoculation of Rhizobium and arbuscular mycorrhiza in presence of poultry litter. From the view point of nodulation, growth, yield attributes, and yields of chickpea, dual inoculation of Rhizobium inoculant and arbuscular mycorrhiza along with poultry litter was considered to be the balanced combination of nutrients for achieving the maximum output from cultivation of chickpea in Shallow Red Brown Terrace Soil of Bangladesh.

The objectives of this study were conducted to determine the effects of two chemical amendments on volatile fatty acids (VFA) and nitrogen contents in poultry litter after broiler chicks were raised in poultry houses for 6 weeks. Two different additives were applied as a top dressing to the litter at a rate of $AlCl_3{\cdot}6H_2O$ (200 g)+$CaCO_3$ (50 g) or Alum (200 g)+$CaCO_3$ (50 g)/kg of rice bran; untreated litter served as controls. Application of $AlCl_3+CaCO_3$ and Alum+$CaCO_3$ reduced total VFA contents by 67% and 51% at 6 weeks, respectively, compard to the control groups. The decrease in litter pH with two chemical treatments results in decreased proportion of VFA and increased nitrogen contents of the litter. These results indicate that treating $AlCl_3+CaCO_3$ and Alum+$CaCO_3$ to poultry litter offers the potential for reducing an environmental impact.

The purpose of this study was to evaluate the effect of sea urchin shell powder, used in broiler diet, on Esherichia coli and Salmonella in litter produced by the broilers. A total of 120 broiler chickens were fed 1 of 3 treatment diets (10 chickens per pen) in a randomized block design treatments with 4 replications. Sea urchin shell powder was used in the concentrations of 0.5% and 1% in the basal diets; the control diet was constituted of basal diet. During the 3-week feeding trials, none of the treatments significantly affected the E. coli populations in poultry litter at weeks 0 and 1, nor did they affect the and S. enterica populations at weeks 1 and 3. However, dietary sea urchin shell powder addition affected the population of E. coli at weeks 2 and 3, and that of S. entericaat weeks 0 and 2 (P<0.05). It is therefore concluded that the use of dietary sea urchin shell powder (0.5% and 1%) will be beneficial enough to reduce E. coli, rather than S. enterica in poultry litter over short-term periods.

A total of 192 one-day-old Ross 308 broilers (initial body weight: 31.30±0.41 g) were used in this experiment for 28 days. Treatments were as follows: basal rice husk (CON), rice husk + 1% illite (T1), rice husk + 1% zeolite (T2), and rice husk + 0.5% illite + 0.5% zeolite (T3). The percentage of illite and zeolite was calculated on a weight of litter. Each treatment had four replicates, with 12 birds per pen. Each pen was provided with 5 kg of rice husk as litter. Litter moisture content was significantly decreased (P<0.05) in the T1, T2, and T3 groups compared to CON group at week 4. In litter nitrogen, the T1 group showed significantly lower (P<0.05) litter nitrogen content than the other groups at weeks 1, 2, and 3. Also, the T3 group showed a significantly lower (P<0.05) litter nitrogen content than the CON and T2 groups at weeks 2 and 3. The counts of E. coli in the litter were significantly decreased (P<0.05) in the T1 group compared to the CON group at weeks 2 and 3. Moreover, the counts of Salmonella in the litter were significantly decreased (P<0.05) in the T1 group compared to the CON group at week 4. The FPD score significantly decreased (P<0.05) in the T1 group compared to the CON group. In conclusion, spraying illite could be an ideal way to improve litter quality and decrease FPD in broilers.

A total of 168 seven days-old Arbor Acres chicks were reared in late-autumn on 4 types of litters; sawdust, rice husk, sugarcane bagasse or wheat straw up to 49 days of age to compare the growth performance, evaluate the manureal value and Coccidial oocyst population in used litter. Sadust, rice husk, sugarcane bagasse and wheat straw did not differ statistically for live weight, feed consumption, feed conversion ratio and survivability (p>0.05). However, live weight and survivability tended to increase on sawdust. The highest moisture content of used litter was found in sugarcane bagasse followed by sawdust, rice husk and wheat straw (p<0.05). Rice husk contained the highest amount of of nitrogen, phosphurus and potassium followed by sawdust, sugarcane bagasse and wheat straw (p<0.01). Oocyst content of all treatment groups increased suddenly up to 5 weeks of age and thereafter suddenly declined up to 7 weeks of age. Litter materials did not differ at 35 and 42 days of age for oocyst content, but significantly differed at 49 days of age (p<0.01). So, the above findings reveal that sawdust may be suitable litter followed by rice husk, sugarcane bagasse and wheat straw in late-autumn in Bangladesh in respect of broiler growth performance.

This study was conducted to evaluate the effects of sea urchin shell powder on nitrogen characteristics in poultry litter by assigning ninety 1-d-old male broiler chicks (Arbor Acres) to one of 3 treatments (control, 1% sea urchin shell powder, and 1% feed additives) in 3 replicates of 10 birds each. For all treatments, the overall dry matter contents were decreased (P < 0.05) as time increased, except for at 1 week. When compared with controls, the dietary sea urchin shell powder and feed additives for 0 and 3 weeks did influence their TN contents, but not for 1, 2 and 4 weeks. The treatments with sea urchin shell powder and feed additives had a significant (P < 0.05) influence on $NH_3$-N in poultry litter compared with controls. However, at 4 weeks, no marked differences were observed in $NH_3$-N contents among treatments. Treatments with 1% sea urchin shell powder might enhance the value of poultry litter as N fertilizer.

This study was conducted to determine the effects of mixed Korean red ginseng marc with aluminum sulfate on gas concentration and volatile fatty acid (VFA) in poultry litter during 4 weeks in terms of livestock and environment managements. A total of 240 broiler chicks were randomly allocated to four treatments in four replications and 15 birds per replicate. The four treatments was mixed to rice hull under each pen at 0, 10 g or 20 g red ginseng marc + 90g aluminum sulfate, and 100g aluminum sulfate per kg poultry litter (rice hulls). Carbon dioxide, methane, acetic acid, and propionic acids were measured weekly. The results that could be available include: First, during the experimental period, carbon dioxide emissions were not remarkably different among treatments. Second, no differences were observed among treatments in methane emissions at 2 weeks through 4 weeks, but at 1 week, the reduction in methane emissions was in following order: 100 g aluminum sulfate > 20 g red ginseng marc + 90 g aluminum sulfate > 10 g red ginseng marc + 90 g aluminum sulfate > control. Third, in spite of statistically differences, treatment with 10 g or 20 g red ginseng marc + 90g aluminum sulfate, and 100g aluminum sulfate reduced acetic acid and propionic acid as a function of time, except acetic acid in aluminum sulfate treatment at 2 and 4 weeks. In conclusion, the results indicated that like aluminum sulfate, using 10 g or 20 g red ginseng marc with aluminum sulfate was effective in decreasing methane and propionic acid released from poultry litter.

The objectives of this study were to determine the effect of applying two different additives to the litter on broiler performance and the carbon dioxide gas production in poultry cages. In two different experiments, the carbon dioxide gas production in poultry litter used for 42 days was measured. The chemical additives were applied to the litter at a rate of 200 g aluminum chloride(A1Cl$_3$ㆍ6$H_2O$) or 200 g aluminum sulfate [Al$_2$(SO$_4$)$_3$ㆍ14$H_2O$, Alum] + 50 g carbon carbonate per kg litter. There was no effect on broiler performance by the litter additives, but the values of carbon dioxide gas produced from broiler litters which were treated with chemical additives were significantly lower(P < 0.05 and 0.01) than that of the control. This study showed that carbon dioxide gas production can be reduced by chemically treating the litter with A1Cl$_3$ or Alum + CaCO$_3$.

Footpad dermatitis (FPD) can be considered as a threat for poultry production due to it causes losses due to condemnation in slaughterhouse. The prevalence and the severity of FPD in broiler breeders increase over time with development of poultry industry. The condition is produced by multifactorial including include drinker design and management, diet composition, house (temperature and humidity levels), litter (type, quality, and quantity) and gut health. Bacterial infections can be associated. FPD lesions can develop in less than a week. FPD is a variable size of inflammatory lesion of the footpad in commercial poultry characterized by necrotic lesions on the plantar surface of the footpad of poultry. These lesions can be exposed after removal of fecal mass and litter stuck on it. There are considerable and numerous interactions between the environment and the genetic traits. Prevention depends mainly on improvement of litter condition. Genetic selection against footpad dermatitis must be contributed to reduce pain and suffering for particular bird experiencing contact dermatitis as well as to avoid economic losses. The objective of this review is to collect different literature written about FPD to be available to students, researchers and veterinarian in poultry practical.

This experiment was conducted to investigate the effect of floor heating system on housing environment and performance in broiler production. PVC heating pipes(in 25cm spacing) were covered with concrete under the litter. Floor heating system was compared with conventional direct heating system. Each treatment had two replicates of 110 birds each. Litter moisture content was significantly reduced in floor heating system than conventional direct heating system(P〈0.05). Dust concentration was higher in floor heating system because of low litter moisture content. CO$_2$concentration was 2,900ppm and 1,500ppm on the direct heating system and floor heating system, respectively at the age of 1 week. Body weight was significantly higher in floor heating system at 7 weeks of age(P〈0.05). The results of the trial show that floor heating was useful heating system for broiler production.
