INTERNAL ORGANS CHAR ACTERISTICS OF NATIVE CHICKEN FED BY COCONUT OIL (Cocos nucifera) ON DIET. The research was carried to determine the internal organs characteristics of buras chickens fed coconut (Cocos mucifera) oil in diet. A total 100 unsexed buras chickens was used in this experiment. The design used in this study was a completely randomized design (CRD) consisting of 5 treatments and 5 replications (4 hens each). The data were subjected to analysis of variance, when the treatments indicated significant effect it was continued Duncan’s Multiple Range Test. Five dietary treatments containing 0, 0.5%, 1 %, 1,5%, and 2% levels of coconut oil (CO) with five replicates were applied to chickens.  Parameters measured were body weight, heart, liver, pancreas  and gizzard weight. Result showed that CO in the ration significantly increased the body weight (P<0.01) but did not affect to heart weight, liver weight, pancreas weight and gizzard weight.(P>0.05) It can be concluded that coconut oil in the diet can’t increase the internal organ characteristics. We can gave the 2% CO in the diet for the best results. Key words: Internal Organs, Coconut Oil, Buras Chickens

AbstractThe experiment was conducted on 10 Wistar rats, male and female, with initial body weight 270–280 g (males) and 250–260 g (females). The drug was administered using a spray cap in 10 doses of 0.1 mg at 45 min intervals. The average cumulative dose of the drug per naloxone hydrochloride was 36.6 mg/kg for males and 39.4 mg/kg for females. The animals were monitored for 2 weeks after the exposure and then euthanized by a gentle decapitation.We noticed that after each drug administration the animals showed a decrease in motor activity. During the observation period there were no animal deaths or signs of abnormalities in their general state or behavior. Beginning on day 7 a significant increase in body weight of the animals was noted in comparison with the initial data. The relative mass of the internal organs of the treated rats remained within the physiological norm.We conclude that naloxone hydrochloride after an intranasal administration at 36.6 mg/kg for males and 39.4 mg/kg for females does not cause death of animals and or have a toxic effect on their general state, does not change their protein metabolism characteristics or the appearance of the internal organs and their mass.

Native breeds of ducks have been the subject of many studies in the past, yet the relevant knowledge is still incomplete and needs to be further expanded. The objective of this study was to provide information about differences in growth performance, dressing percentage, carcass composition and digestive morphometry among three lines of Pekin ducks from conservation flocks raised in Poland. The study used 180 sexed Pekin ducks—30 males and 30 females of line P33 (ducks of Polish origin), 30 males and 30 females of line P8 (ducks of Danish origin), and 30 males and 30 females of line P9 (ducks of French origin). Throughout the study (49 d), ducks were confined indoors in six pens. Birds were fed complete commercial diets ad libitum and had unrestricted access to water. The compared lines of ducks differed significantly in body weight from 1 to 49 d of age except of ducks of both sexes at 14 d. At 49 d of age, significant differences were observed between the tested ducks in all the body measurements. Duck genotype had a significant effect on preslaughter body weight, carcass weight and breast muscle, neck and remainders contents, caeca length, liver weight and gizzard percentage. The results show that the tested ducks were significantly different and unique, mainly in terms of the body biometric characteristics.

SUMMARYFlocks of 9-month-old Merino and Border Leicester & Merino sheep were sampled over the full range of body weights present within flocks. Six pairs of ewes and wethers of equal body weight were taken. The sheep were weighed and slaughtered after a 36 h fast. Total weights of blood, skin, head, feet, internal organs and carcasses were obtained for each animal. Each component was analysed for ash, crude protein, ether extract and total energy. Half of each carcass was dissected into bone, muscle, fat and waste.The compositions of the sheep were compared by regression analyses of weights of body components on empty body weight (EBW) between the four groups and by means of percentages of EBW. There were highly significant linear relationships between both fresh and dry weights of body components, carcass components, and chemical components with EBW; moisture content was not related to EBW. Rates of change with EBW in weights of body components, or in amounts of ash, crude protein, ether extract and energy were the same for all groups of sheep with the exceptions of bone and skin ether extract (EE) weight. However, intercepts of regression lines frequently differed, indicating that body composition differed between groups at the same EBW.All groups had the same dry weight of blood, internal organs and muscle, weight of ether extract, and total energy in the whole body at the same EBW. Border Leicester × Merinos had lighter skins with less wool, but their carcass weights were higher than Merinos. There were other differences between breeds in the chemical composition of individual components. Wethers had heavier head + feet weights and carcass bone than had ewes. There were also some sex differences in chemical composition of body components. In general, there were fewer sex than breed differences in body composition. The breed differences cannot be explained on the basis of early and later maturing types.

Nineteen young and eighteen mature lean Holstein cows were purchased from a commercial source and fed a high energy diet ad libitum based on high moisture corn and haylage. Six young and six mature cows were slaughtered at the start of the trial to give an estimate of the initial weight of the offal components. After 68 days on feed, two young cows and two mature cows were slaughtered on a weekly basis until the conclusion of the trial. The offal components were weighed fresh and the alimentary components emptied of digesta. The growth pattern of each offal component relative to empty body weight was estimated from the allometric equation (Y = aXb). Growth coefficients were homogeneous between young and mature cows, indicating that cow age did not influence the relative growth of offal. The internal organs concerned with vital body functions tended to be related to empty body weight to the power of 0.67, which is proportional to the basal metabolic rate. The internal fat depots, however, all had growth coefficients in excess of one. At a constant empty body weight young cows had heavier hides (P < 0.5) and tended to have less hot carcass weight (5.4 kg) than mature cows.

Toxicological study of L-asparaginase Was79, obtained by modification of native enzyme Wolinella succinogenes in Research Institute of Genetics and Selection, was performed in male and female inbred rats. L-asparaginase was injected intraperitoneally at the 1 and 10 therapeutic dose (15x1200 IU/kg or 15x12000 IU/kg with 24-h interval). Dynamics of body weight, hematological parameters, blood biochemical parameters, electrocardiography and urinalysis were performed for all animals. Five animals in each group were sacrificed 1 and 15 days post treatment. At necropsy, the organs were inspected macroscopically. The mass coefficients of heart, kidneys, liver, spleen and thymus were calculated. The pathomorphological evaluation was performed for internal organs. The results of the study demonstrate that the treatment with L-asparaginase Was79 did not produce any changes in body weight, hematology, blood biochemical or urinary parameters. Hematological, renal, gastrointestinal, and pancreatic toxicity of L-asparaginase have been documented only by microscopic pathology observation. Liver toxicity, revealed in the histopathological findings, was supported by the results of clinical chemistry. Marked elevation of ALT and alkaline phosphatase in serum was found in both treated groups. Most of these abnormalities were reversible and dose-dependent.

The aim of this study was to evaluate the effect of monochromatic light on broiler performance, fear and stress response during pre-slaughter handling and transportation. Two thousand unsexed one-day old Cobb broiler chicks were used. At day 34, two hundreds broilers of similar live body weight were selected and divided into two equal groups (2 group x 5 replicates). Broilers were reared under white light (WL) from 0-34 day. From 35 to 49 day, the first group was reared under WL and the second group under blue light (BL). Final body weight (FBW), tonic immobility reactions (TI), respiratory rate (RR), heterophils to lymphocytes (H/L) ratio and interlukien-1? (IL-1?) were estimated at day 49 before and after transportation. After transportation, weight of internal organs (liver, spleen, heart and bursa of fabricius) as a percentage of FBW was calculated. Results showed that there was a significant (P<0.05) increase in FBW and reduced weight loss due to transportation in broilers reared under BL. In broilers reared under BL: TI duration, RR, H/L ratio, IL-1? and weight of internal organs (except the heart) were significantly (P < 0.05) lower. The interaction effect of light and transportation on TI duration, RR, lymphocytes, H/L ratio and IL-1? were significant (P < 0.05). Therefore, it is suggested that BL may be a good tool for improving welfare and mitigating stress not only in pre-slaughter handling but also during transportation of broilers.

Abstract This study aimed to develop equations to predict the empty body weight (EBW) using the shrunk body weight (SBW) of water buffaloes of three genetic groups (GG:Jafarabadi, Mediterranean, and Murrah; n = 65 for each GG), considering possible variations among GG. One-hundred-ninety-five non-castrated males (390±32 days of age; 327±51.96 kg of initial body weight - BW) from two years of similar experiments were used. Animals of each GG were allocated in collective pens for 28 days of adaptation period. Diet and water were offered ad libitum. Animal SBW were recorded at the beginning and every 28 days until the averages SBW reached the values determined (420, 480, and 540kg of SBW). After slaughter and to obtain the EBW, the non-carcass components of each animal [blood, paws, head, leather, tail, gastrointestinal tract (GIT), liver, kidneys, internal fat, and other internal organs] were weighed. The full GIT of each animal was weighed to obtain the total weight, and then emptied, washed, drained, and weighed to obtain the weight of the GIT content. Initially, data were analyzed using UNIVARIATE procedure in SAS. SBW recorded prior to slaughter were categorized according to SBW proposed considering the coefficient of variation below 10% for each GG to increase the precision of the data used, which decreased the initial n to 104 animals. Equations were developed and tested for GG effect using GLM and REG procedures in SAS. Tendency of GG effect was detected (P = 0.06). Thus, different prediction equations were determined for each GG, and a general prediction equation was developed for the three GG (Table 1). In conclusion, the results suggest it is possible to use distinct equations to predict the EBW according to GG as well as a general equation can be also used, resulting in high predictions of EBW of water buffaloes finished in feedlot.

Introduction. Currently, many xenobiotics are widely used in industry and agriculture, which can cause serious disorders of pregnancy and fetal development. In this regard, the study of the effect of pesticides on embryogenesis in experiments on laboratory animals is a mandatory stage of sanitary and Toxicological research. The aim of the study was to investigate the long-term effects of a compound of the class of benzothiadiazinones for the assessment of embryotoxic and teratogenic effects, as well as reproductive toxicity by the method of two generations, with repeated oral intake of it into the body of warm-blooded animals (rats), establishing the levels of inactive doses for parents and offspring, and determining the hazard class. Material and methods. The embryotoxic and teratogenic effects were evaluated in female and male rats with a bodyweight of 230-240 g at the beginning of the study. Tested doses: 40.0; 100.0 and 250.0 mg / kg body weight (1 control and 3 experimental groups, 15 individuals each). Mating of females was performed with intact males in a ratio of 2:1. the Compound was introduced during 20 days of pregnancy. In the dynamics of the experiment, the state and behavior of rats, water and feed consumption, and changes in body weight were observed. The analysis of embryonic material took into account: the absolute and relative mass of internal organs (thymus, heart, lungs, liver, kidneys), to determine the teratogenic effect, a group of fruits (1/3) was fixed in Buena fluid and used to study internal organs using the Wilson method modified by Dyban the remaining 1/3 of the fetuses was fixed in ethanol to study the state of the skeleton using the Dawson method. When studying the reproductive toxicity of benzothiadiazinones in mammals (rats) using the method of two generations at doses of 15.0; 50.0 and 200.0 mg/kg of body weight (1 control and 3 experimental groups, 20 individuals each). Female F0 of the parent generation was primed during the mating period, pregnancy, and continued until the end of the feeding of the F2 generation. Mating 2:1. Results. Based on the results of studying the embryotoxic and teratogenic effects, invalid doses were established at the following levels: Noel for the mother - 100.0 mg/kg of body weight; Noel for embryotoxicity - 100.0 mg/kg of body weight; NOEL for teratogenicity-100.0 mg/kg of body weight. Results on the study of reproductive activity: NOEL for parents and offspring-50.0 mg/kg of body weight. Discussion. Studies on the effects of a long-term action of a technical product - “generic”, belonging to the class of benzothiadiazinones, found the studied compound for teratogenic, embryotoxic effects, as well as for its effect on reproductive toxicity, in accordance with the hygienic classification of pesticides by hazard (SanPiN 1.2.2584-10)to be a moderately dangerous compound (hazard class 3). Studied product class benzothiadiazinones on toxicological parameters are identical with the technical product is “originator”. Conclusion. Thus, the research shows that it is necessary to study the effects of long-term action of xenobiotics on the mammalian body when conducting sanitary and toxicological studies, to increase the reliability of the developed hygiene standards in environmental objects and food products.

We studied the chronic toxicity of the compounds of Iron(iv). We monitored the dynamics of the body weight, relative weight coefficients of the internal organs, the content of the hemoglobin, the morphological parameters of blood, and biochemical parameters of serum of blood of quails after use of Iron(IV) clathrochelate complexes at the doses 1/10 and 1/5 DL50 them for 30 days. Daily drinking of quails of experimental groups of solution of Iron(IV) clathrochelate complexes3 at the doses 76.43 and 152.86 mg/kg of body weight caused the reduction of body weight by 3 and 5% respectively on the thirtieth day. A tendency to increase the relative weight of the kidneys and to decrease the relative weight of the liver, heart and spleen showed an excessive load of Iron(IV) clathrochelate complexes on the internal organs of quails. Hemoglobin in the blood of the quails of the experimental groups was less by 2-34% (P 0.05) than the control indicator but the indicator of the number of erythrocytes in the quails of the control and experimental groups for 30 days was within the physiological values. The use of Iron(IV) clathrochelate complexes caused the development of hypoproteinemia, hypoalbuminemia, and short-term hypoglycemia in the serum of the blood of the quails of the experimental groups. Changes in an activity of alanine aminotransferase and aspartate aminotransferase for 30 days were not expressed, but the activity of alkaline phosphatase was significantly higher compared to the control indicators during the experimental period. Drinking the solution of Iron(IV) clathrochelate complexes caused hypercreatinemia and hyperuricemia, which indicates a decrease in the filtration capacity of the kidney glomeruli. We have seen an increase in the levels total Calcium and inorganic Phosphorus.
