The current experiment was conducted to assess the effect of using different litter types with or without alum on performance and litter quality of the hen layers. A total number of 120 Inshas layer hens of 24 weeks of age were randomly distributed into 4 groups (3 replicates each 10 hens) of floor litter: T1 birds were raised on wood shaving litter, T2 birds were raised on wheat straw litter, T3 birds were raised wood shaving with 100 g of alum / kg of bedding, and T4 birds were raised on wheat straw litter with 100 g of alum / kg of bedding. Topping of fresh litter with acidifier amendment improved body weight, egg weight, egg number, egg mass, feed intake and feed conversion ratio of layers compared to chickens in the untreated litter group. In comparison with the control group, alum treatment reduced the pH level of the litter. Regarding the NH4+-N content, alum-treated litter showed a higher value than the untreated litter. On average, alum-treated litter had lower P content than the untreated litter. Alum treated group showed a significant increase in dry matter and total nitrogen content when compared with the untreated group. The study results showed significant variability (p < .05) in the moisture content and pH of the control and treated litter. This clearly shows the effectiveness of litter treatment products enhancing litter quality and therefore the bird’s environmental climate. Thus it can be decided that litter modification with alum treatment had a significant impact on litter quality and in turn enhanced the productive performance of layer chickens without any adverse effect.

The present study aimed to evaluate the effect of dietary Moringa oleifera (M. oleifera) leaves and/or seed powder on laying Japanese quail performance in terms of egg production, egg quality, blood serum characteristics, and reproduction. In total, 168 Japanese quails (120 hens and 48 males) at eight weeks of age in laying period were randomly distributed to four treatment groups, with six replicates per group and seven birds (five hens and two males) per replicate. The first group (G1) served as a control group, while G2, G3 and G4 groups were supplemented with M. oleifera leaves (ML) and M. oleifera seeds (MS) and their combination ((1 g/kg ML; 1 g/kg MS; and 1 ML g/kg + 1 MS g/kg (MSL), respectively). From the results, feed consumption, feed conversion ratio, egg weight, fertility and hatchability from fertile eggs, egg and yolk index, and Haugh unit were not affected by dietary treatments. However, egg production, egg mass, eggshell thickness, and hatchability were significantly increased and blood aspartate transaminase (AST) and urea decreased in the MS treatment. Both triglycerides and total cholesterol were reduced (p < 0.05) in all treatments with ML, MS, and MSL, with no significant differences in alanine aminotransferase (ALT), albumin, total protein, globulin, and A/G ratio among dietary treatment. Our results clearly indicated that the inclusion of M. oleifera seeds in Japanese quail diet significantly increased egg production and improved hatchability, along with some egg quality parameters, and also lowered some blood biochemical components.

ABSTRACT A non-surgical sterilant (NSS) was used with the objective of assessing the zootechnical performance, carcass and meat quality, and hormone levels. 90 male piglets were selected with birthweights varying between 1.5kg to 2.0kg. The control group was constituted of 45 males castrated by the conventional surgical method, at the seventh day of age, and the treated group was constituted of 45 males castrated with NSS (active principle of zinc gluconate in the concentration of 26.2mg/mL associated to the dimethyl sulfoxide at 0.5%), with the application of the first dose on the seventh day of age and the second dose on the fourteenth day of age. The zootechnical assessments were carried out on the farm and consisted: weight gain in the periods per animal and feed conversion. The slaughter of the animals and the assessment of the carcass and meat quality and hormone levels were carried out in a slaughterhouse and the municipality of Campinas (SP). The study demonstrated that the use of NSS was a viable alternative in relation to the zootechnical performance and the carcass quality. In relation to the meat quality there was no significant difference in the majority of the assessed parameters.

Study Results

The anti-diabetic effect of ethanolic and aqueous extracts of Imperata cylindrical  rhizomes was investigated in alloxan-induced diabeties in rats. Diabetes was induced by a single 150 mg/kg intraperitoneal dose of alloxan. Rats were divided into five groups with six rats in each group i.e. the normal control group, diabetic control group, standard group (glibenclamide, 10mg/kg, p.o.), Test-I group (200 mg/kg ethanolic extract) and Test-II group (200 mg/kg aqueous extract). The above concerned groups were inoculated on 21st day. On the last day of the experiment, fasted rats were killed by cervical dislocation. The body weight was measured at the initial day and final day. The blood samples were collected for estimation of glucose. The loss of body weight in control group, but recovery was observed in drug treated group. The serum glucose level was significant increased in diabetic rats. However, significant improvement was observed in treated group. The biochemical parameters such as HDL and proteins level were decreased in the control group but maintained in drug treated group. LDL, cholesterol, triglyceride creatinine and urea were significant increase in control group however, reduced level in drug treated group. The present study concluded that ethanolic and aqueous extracts of I. cylindrical  rhizome showed an appreciable effect in reducing the hyperglycemia and the complications associated with diabetes. However, aqueous extract is found more significant in decreasing blood glucose level in comparison to the ethanolic extract. The study results justify the traditional use of the plant as anti-diabetic.

PURPOSE: To study the effect of alcoholism on intestinal healing and postoperative complications in rats METHODS: One hundred and sixty rats were divided into two groups: control and treated. The control group received water and the treated group 30% ethanol. After 180 days, colotomy with anastomosis were performed. After, the groups were divided into four subgroups: 20 rats for study at the following moments: 4th, 7th, 14th and 21st postoperative. The analyzed parameters were: weight gain, breaking strength, tissue hydroxyproline, postoperative complications and histopathological study RESULTS: Weight gain was greater in the control group (p<0.05). When all the subgroups were clustered, breaking strength was significantly greater in the control (p<0.05). Histopathology and hydroxyproline dosage did not show differences. There were five surgical site infections in the treated group while the control group showed two (p>0.05). Nine fistulas occurred in the treated group whereas the control group two (p<0.05). There were three deaths in the control group and seven in the treated group (p>0.05). CONCLUSIONS: Treated group undergo a malnutrition process that is revealed by lower weight gain. Impaired intestinal healing as indicated by smaller breaking strength. There were a larger number of postoperative complications in the treated animals.

The article presents the study results on the fattening effectiveness of Texas Broiler quails using the formulated feed with “B.I.O. Acid Ultra” acidifier. Space and layout design of the mini-farm allowed to house 1000 head of the main flock and up to 300 young birds. The inside climate system of the mini-farm maintained the temperature in the range of 18 °C -20 °C and 75% humidity. In the study, 250 head of daily chicks were randomly selected and divided into 5 groups of 50 head each – one control group and four experimental ones. The study lasted for 8 weeks, i.e. the meat quail fattening period. The addition of the acidifier to the diet in the amount of 0.23% was found to result in 9.0% increase in the bodyweight of the 8-week old quails. The average daily weight increments also increased during the entire fattening period. The use of the acidifier reduced the feed conversion ratio by 4.1% – 6.79 versus 7.1 in the control group. However, the effect of different acidifiers on the effectiveness of quail fattening and the organoleptic and other quality indicators of the quail meat requires further comparative inquiry.

The present study determined, assessed and quantified the exogenous phytase on egg production and egg quality of spent hens. Ninety laying hens (ISA- Brown) received iso-energetic and iso-nitrogenous diet supplemented with 0, 0.05, 0.1, 0.15 and 0.2 % phytase and reared in cages. Each layer was fed 120g feed/day from 90 to 100 weeks of age. At the inception of the study the spent hen at the age of 90 weeks had an average egg production 65.21 %. Phytase addition in diet increased (p<0.05) egg production  (7.67, 12.17, 12.04 and 15.87 % higher than control group), egg mass output (5.5, 9.34, 7.65 and 12.72 % higher than that of control) and feed conversion, but it did not alter shell weight, shell thickness, shape index, albumen index, Haugh unit, per cent yolk and yolk color. It was concluded that reduced egg production of spent hen at older ages to some extent might have a relationship to decreased availability of phosphorus. The decreased egg production in hens at older ages could be corrected by adding appropriate phytase level in the diet. Thus, it may be possible to extend and prolonged productive life of spent hens by supplying exogenous phytase in diet. However, the effect of availability of phosphorus on egg production using larger population for a longer period may be performed to confirm the findings of the current study.

Background and Aim: Recently, many medicinal plants have received considerable attention in the medical field because of their role in the wound healing potential. This study aimed to determine the effectiveness of H. tuberosus powder on the healing pathway of full-thickness cutaneous wounds in a mouse model. Materials and Methods: H. tuberosus powder was prepared by a freeze-drying process using a lyophilizer and its active ingredients were evaluated by high-performance liquid chromatography (HPLC), while its antibacterial properties were evaluated by agar well diffusion assay. The percentage wound contraction was also assessed. Thirty mice were used, which were divided equally into two groups, a control group and a treated group. A full-thickness wound, 1 cm×1 cm in size, was established on the dorsal aspect of the thoracolumbar region, into which H. tuberosus powder was topically applied in the treated group. In contrast, the control group was left without any treatment. The animals were euthanized on days 7, 14, and 21 after wounding for histopathological study. Results: The agar well diffusion method indicated the antibacterial activity of H. tuberosus, while the HPLC results indicated that the active ingredients of H. tuberosus powder mainly consisted of three major kinds of fatty acid. In addition, the macroscopic results of wound contraction rate and the histopathological outcomes of the healing process were significantly (p≤0.05) enhanced in the treated group compared with those in the control group. Conclusion: H. tuberosus powder acts as an antibacterial agent with the ability to enhance the wound healing process.

The study was conducted with an aim to investigate the effect of litter density on growth, leg health and litter quality of broiler chickens from d1-42 days. Day-old male broiler chicks (n=400; Cobb 500) were distributed randomly into four litter densities [T1, T2, T3 and T4] treatments, each treatment had 5 replicates with 20 birds per replicate cage in a completely randomized design. Wood shaving was used as litter materials to a thickness of 5 cm, 8 cm, 11 cm and 14 cm on the floor of the pen. Birds were reared on the litter floor open-sided housing condition with ad libitum feed and water throughout the trail period. Data on feed intake (FI), body weight (BW), feed conversion ratio (FCR) and mortality were measured weekly. Litter sample was collected on day 42 to assess the nitrogen content (N2 %), dry matter (DM%) and moisture level (%). Footpad dermatitis (FPD) and hock burn (HB) incidences were measured on day 42 to assess the leg quality of birds. Results demonstrated that litter thickness had no significant (P>0.05) effect on FI, BW, FCR and mortality of broilers from d1-42 days. The N2, DM or moisture levels (%) of litter were also unaffected (P>0.05) between treatment. Leg disorders such as HB and FPD were influenced (P<0.01) by treatment. The incidences of HB and FPD were higher (P<0.01) in T1 and T2 than other treatments. It can be inferred from our current study that, leg health may be deteriorated by using low density wood shaving without affecting growth and litter quality of broiler chickens. Bang. J. Anim.

AbstractTwo groups of six Haemonchus contortus infected Saint Croix lambs each received different diets for 11 weeks: control group, commercial food, molasses and lucerne hay; and treated group, nutritional pellets (NPs) containing Duddingtonia flagrans at 2 × 106 chlamydospores/kg body weight (BW), sorghum and lucerne hay. Mean BW gain (BWG), body condition score (BCS) and packed cell volume (PCV) and also eggs/g of faeces (EPG) and recovered L3 were compared using a repeated measures across time model. Groups had similar BWG (control 139.7 ± 0.035 g/day and treated 167.7 ± 0.041 g/day), BCS (control 3.6 ± 0.39 and treated 3.4 ± 0.46) and PCV (control 32.5 ± 1.68% and treated 30.0 ± 1.68%). The mean EPG of the control group was 1215 ± 1040 and in the treated group it was 2097.91 ± 2050. No reduction in larval population was observed during weeks 2 and 3. The greatest larval population reduction in the faeces of treated lambs was observed during the first week (70.5%) and from weeks 6 to 11, with a mean value close to 70% (P < 0.05). In general, both experimental groups showed a similar feed conversion. It was concluded that both diets resulted in similar lamb growth, PCV, BCS and H. contortus EPG. However, NP consumption significantly reduced the H. contortus L3 population in lamb faeces.

The aim of this research was to observe the influence of palm kernel meal and ß-Mannanase on laying hens. Laying hens up to 2500 birds were reared in opened-house cage fed with commercial feed substituted with palm kernel meal and ß-Mannanase. All hens were divided into five groups in an order P0 as control group, groups without enzyme which are P1 with 7% palm kernel meal and P2 with 14% palm kernel meal, groups with ß-Mannanase which are P3 7% palm kernel meal and P4 with 14% palm kernel meal. The observed variables are feed intake, feed cost, egg weight, egg mass, feed conversion ratio, hen day production, and mortality rate. The results indicated that threr are no significant difference from all variables. The percentage of palm kernel meal for 14% with ß-Mannanase cannot give any influence on laying hens productivity.
