Abstract. The average weight and flock uniformity of broilers in group housing is important information that allows producers to know the flock growth conditions and determine the selling time. However, gathering weight information of chickens is not only labor-intensive for humans but also frightening for the birds. In this study, an image-assisted rod-platform weighing system was developed to automatically monitor the average weight and flock uniformity of broilers in chicken houses. This weighing system consists of a computer and several weighing scales. Each weighing scale contains a rod-platform weighing module and a surveillance camera module. The principle of the automated weighing system is to estimate population weight information using samples. The design of the rod-platform weighing module was based on the perching habit of birds to attract more broilers to stand on the rod platform and thus get more weight samples. The surveillance camera module is used to detect the number of broilers on the rod using image processing technology. A data processing method called PORWI, which includes elimination of redundant records and trim of non-redundant records, was designed to optimize the results of chicken number identification from images to improve the accuracy of the results. An experiment was done in two small groups of broilers with approximately 100 chickens and 8.58 m2 of area for each group. A weekly weighing was conducted, and three kinds of weight information were obtained, which included manual population weight information (MPWI), manual sample-based weight information (MSWI), and automated sampling weight information (ASWI). Each weight information set comprised the group average weight and flock uniformity, which were then used to evaluate accuracy. The perching rate of chickens using the rod platform reached an average of 60 times h-1, and the rate was retained with increasing age. Compared with the MPWI obtained by individual weighing, the manual sample-based measurement method provided results with errors of 0% to +5%, while our automated weighing system achieved accuracies within ±2% for average weight and ±1.5% for flock uniformity. Keywords: Automatic weighing, Average weight, Broiler, Chicken detection, Uniformity.

PURPOSE: To evaluate and to compare macro and microscopically the intense injuries of the gastric mucosa of rats which were caused by NSAIDS celecoxib and indomethacin and the gastric cytoprotection with omeprazole and misoprostol. METHODS: The sample is formed by one hundred and fifty Wistar rats with average weight 200 g, distributed in four groups, such as: Group A, subdivided in groups A1 and A2 - pre-treatment with omeprazole (20 mg/rat) during seven days and on the 8th day - use of NSAIDS, concerning A1 (20 rats) were given celecoxib (1mg/rat) and A2 (20 rats) were given indomethacin. The Group B, subdivided in group B1 and B2 - pre-treatment with misoprostol (20mg/rat) during seven days and on the 8th day use of NSAIDS, concerning B1 (20 rats) were given celecoxib (1 mg/ rat) and B2 (20 rats) were given indomethacin (12.5 mg/rat). The Group C: were not given cytoprotection during seven days, from the 7th to the 8th day - fast of food and water ad libitum, on the 8th day of NSAIDS use, concerning C1 (20 rats) were given celecoxib, C2 (20 rats) were given indomethacin (12.5 mg/ rat), C3 (20 rats) were given celecoxib (200mg/rato), and Group D - control group, concerning 10 rats were observed during seven days ingesting food and water ad libitum. On the 9th day, the stomachs were taken out and were macro and microscopically evaluated for the identification of the gastric injuries. RESULTS: On the macroscopic studies, the groups A2, B2 and C2 presented a remarkable high number of injuries for cm² /animal, respectively 18.55 injuries for cm² /animal, 16.25 injuries for cm² /animal and 13.55 injuries for cm²/animal. On the microscopic studies, the percentage of the injured mucosa, presented expressive difference among the groups A1, B1, C1 when compared to the groups A2, B2, C2 (p<0.0001). The average of the length/injury and the average of the depth of the injuries did not present expressive statistics differences among the groups A2, B2 and C2. The average of the edema presented expressive statistics difference among the groups A2 and D; B2 and C2 and between C2 and D (p < 0.05). CONCLUSIONS: The indomethacin on the applied concentration causes a great number of macroscopic and microscopic injuries to gastric mucosa of rats when compared to celecoxib which does not cause lesions. Omeprazole and misoprostol on the applied concentrations do not present macroscopic and microscopic effectiveness on the gastric cytoprotection when applying indomethacin. Considering the microscopic analysis of the average of the edema, the group of animals, which was given misoprostol as cytoprotection, presented a lower average compared to the group which was given omeprazole.

Background/Aim. The delay method is a surgical, pharmacological and combined method that includes two or more time separated phases, which gives bigger flap surface. In our research we explored the possibility of flap surface enlargement in a new arterialised venous flap (AVF) on an experimental rabbit ear model by the delay surgical method. The aim of this research was to establish vitality surface of our AVF and to maintain the difference in flap vital surface between AVF flaps, with or without performing the delay surgery method. Methods. We used both ears of ?Big Chinchilla? rabbits in 10 experimental male animals, divided into two groups, average weight 3-3.5 kg, and average age 8-10 months. In the first (experimental) group, a venous flap was arterialised by our method. In the second (control) group, the venous flap was arterialised 14 days after the delay surgical method. AVF surface was measured on the 1 and 14 days by the method of trapezoid rule. Results. Vital surface on our AVF experimental model was bigger than 87% of elevated flap surface after the delay surgical method. Vital surface on AVF without delay on our experimental model was bigger than 30% of elevated flap surface (p < 0.001). Conclusion. Analysis of previous experimental models on the rabbit ear, non-delayed and delayed (to enlarge flap surface) led us to conclusion that previously created experimental models of non-delayed AVF are hemodynamically negative. Our experimental non-delay AVF model is hemodynamically more positive than previously created models of non-delay AVF and provides better conditions for AVF survival and enlargement of vital flap surface of elevated flap. On the other hand, surgical delay method significantly enlarges vital surface of AFF.

Cleome gynandra is a medicinal plant that is used all over Uganda to hasten childbirth because, it possesses the ability to contract the uterus. It is also used as an abortifacient in the first trimester. In this study, the effects of Cleome gynandra were investigated on the estrous cycle and the histology of the ovary and uterus of adult Wistar rat. Twelve adult female Wistar rats of 130-140g average weight were used. These were divided into three groups of four animals each. Group A received distilled water only, while animals in groups B and C received 250mg/kg body weight and 500mg/kg body weight of extract, orally and daily respectively. Monitoring of estrous cycle continued throughout the three weeks of extract administration. After three weeks, the ovaries and uteri were excised and processed for histological examination. In the ovary, there was a reduction in number of primordia, primary, secondary and graafian follicles in the treated groups. Vacuolations were common to both the ovarian and uterine tissues of treated animals. The estrous cycle of Group B and C, showed a mild disruption when compared to animals in Group A. The results showed that the plant extract studied, exerted negative influences on the estrous cycle and histology of the ovary and uterus of Wistar albino rats, suggesting a disturbance on the reproductive health of the animals. Further studies to determine the mechanism of action of Cleome gynandra on the ovary and uterus and the levels of FSH, LH, estradiol and progesterone is recommended.Key Words: Cleome gynandra, estrous cycle, Wistar albino rats, ovarian follicles.

Two hundred and forty (240), unsexed day old Arbor Acre broiler chicks were used to evaluate the effects of replacing whole kenaf (Hibiscus cannabinus L.) seed meal (WKSM) with full fat soybean meal (FFSM) in the diets on the performance and carcass characteristics of broiler chicken in a 2 x 4 factorial arrangement, consisting two processing methods (raw kenaf seed meal RKM and roasted kenaf seed meal HKM) and 4 inclusion levels (0%, 10%, 20% and 30%). Both RKM and HKM were analysed for anti-nutritive factors, data were collected on performance, carcass characteristics and cost benefit. The results of anti-nutritive factors (ANF) in RKM and HKM revealed that HKM had lower values of 0.045%, 0.029mg/g and 0.013mg/g for tannin, oxalate and phytic acid respectively when compared to 0.078%,0.124mg/g and 0.026mg/g obtained for RKM (P<0.05). The performance of broiler chicken showed that birds on 10% RKM with an average weight gain and FCR of (2640.00g and 2.48) competed favourably with the control (2554.67g and 2.45). The results of carcass characteristics showed that birds on 10% and 20% inclusion levels had significantly (P<0.05) higher values of 64.25% and 65.58% for dressed weight respectively. In terms of weight gain and FCR, birds fed RKM performed better than birds fed roasted kenaf meal HKM. About 5% feed cost savings was made when WKSM was included in the diets of broilers. It was concluded that RKM and RKM can replace FFSB in broiler diets up to 10% without any detrimental effect on performance and carcass quality.

Background: The use of medicinal plants as fertility enhancer in human is now on the increase because of the shifting of attention from synthetic drug to natural plants. Carpolobia lutea (CL) is a popular aphrodisiac herbal medicine, known for curing male sterility; increasing libido; induction of penile erection; enhancement of aphrodisiac prowess; enhancement of virility and male fertility; and augmentation of male sexual functions. The present study was therefore designed to investigate the fertility enhancement ability and possible side effect(s) of CL in male rats and also to provide insight and added to the existing knowledge available in the society on the usage of CL. Methods: A total of 20 Wistar rats with average weight of 162g were randomly grouped into 4 groups (A, B, C and D) of 5 rats per group, with group A served as the control and was administered normal saline. The remaining 3 groups (B-D) were orally administered 47mg/kgbw, 94mg/kgbw and 141mg/kgbw of Carpolobia lutea (CL) respectively for 60 days before sacrifice by cervical dislocation method. Results: The results obtained show ed that the blood testosterone of the treated rats reduced significantly. The morphometric result was good with significant increase in cross sectional area and luminal diameters in rats exposed to 141mg/kgbw and germinal epithelial diameter in rats exposed to 47mg/kgbw and 141mg/kgbw. Semen parameters showed that the sperm count was significantly increased at the high doses of 94mg/kgbw and 141mg/kgbw. The percentage of motile sperm also increased significantly while the morphological grading showed no changes at all. The experimental rats testes showed no visible lesions or the lesion was very mild (20%), seminiferous tubules were normal and concentric with intact basal membrane and lumen containing matured sperm cells together with the interstitial spaces which are well delineated and defined. Conclusion: It was concluded that the consumption of CL stem in any form can enhance the normal anatomy and physiology of testes at moderate dose and may account in part for the rationale behind its use in the management of sexual dysfunction.

ABSTRACT Escherichia coli clonal group A isolates cause infections in people. We investigated 158 phylogroup D E. coli isolates from animals, meat, and humans. Twenty-five of these isolates were of clonal group A, and 15 isolates were shown to cause infection in a mouse urinary tract infection (UTI) model. We conclude that clonal group A isolates are found in both broiler chickens and broiler chicken meat and may cause UTI in humans.

Summary Objective: The aim was to compare osseointegration of blood perfused β-tricalcium phosphate cylinders (β-TCPB) with similar composites that were additionally loaded with cancellous bone and bone marrow (β-TCPB/BM/CB) for mandibular reconstruction. Methods: Twelve German Black-Headed sheep with an average weight of 72.5 ± 10 kg underwent segmental re-section of the right hemi-mandible. The animals that were assigned to group A (n=6) were reconstructed using β-TCPB while the sheep that were assigned to group B received β-TCPB/BM/CB grafts. Tissue quality was histologically assessed and bone-, scaffold-, cartilage- and fibrous-tissue area were estimated using semiautomated histomorphometrical software. Results: Composite grafts that were loaded with bone marrow and cancellous bone (β-TCPB/BM/CB) exhibited significant (p<0.01) higher amounts of bone formation than β-TCPB. The patients that were assigned to group B achieved defect union and a high grade of bone maturation. Residual ceramic remnants were rare and disconnected. Bone maturity within group A was inferior and none of the specimens showed defect union. The defect centre was still occupied by a ceramic core. Clinical significance: Bone and bone marrow augmented β-tricalcium phosphate composites may qualify as a promising alternative to autograft bone for mandibular reconstruction in human and veterinary medicine.

The study aimed to examine the effect of using pollard in rations on the growth of proventricular, ventricular, duodenal, jejunal and ileal organs in 7-week-old broiler chickens. The research material used 200 broiler chickens aged 7 weeks with an average weight of 859 ± 59 g with each experimental unit consisting of 8 - 9 tails. The design used was a completely randomized design with 5 treatments and 3 replications. Treatment is given (T0 = Comersial feeds, T1 = Feed with pollard without processing, T2 = Feed with pollard treated physically, T3 = Feed with pollard treated physically and biologically, and T4 = Feed with pollard treated physically and biology 60%) and 3 replications. Based on the results of the study it can be concluded that the administration of pollard treated physically and biologically has not been able to increase all the relative weights of the digestive organs of broiler chickens aged 7 weeks. In the proventriculus organ, the treatment can increase the relative weight of broiler digestive organs, but the relative weight of the proventriculus produced is still relatively normal. Measurement of broiler chicken organ weight needs to be done per week to determine the rate of increase in the relative weight of the optimal digestive organs, so that the maximum data on the growth of broiler organs are obtained optimally

Background: Monosodium glutamate (MSG) a sodium salt of naturally occurring (non-essential) L-form of glutamic acid is one of the main flavor enhancer used as an ingredient in various food products. It is widely used in restaurants, packaged food industries and household kitchens, in Nigeria, most communities and individuals often use MSG as a bleaching agent for the removal of stains from clothes. Materials and Methods: Twenty (20) female adult wistar rats were used for this experiment. The rats with average weight of 181g were randomly assigned into four groups of five each (Groups A, B, C and D). Group A, B and C served as treatments groups while group D as the control. Each rat in the treatment groups A, B and C received 0.1g/kg, 0.15g/kg and 0.20g/kg of monosodium glutamate respectively in 0.5ml of water orally three times daily for two weeks. Result: The histopathological evaluation of the tissues of the ovary showed Infiltration of inflammatory cells in and around the oocyte as well as in the zonal granulosa layer. There was distortion of tissue architecture. Conclusion: MSG alters the histology of the ovary, therefore its consumption should be stopped and to work out safe level of consumption further in depth studies are recommended.
