SUMMARYIn an experiment conducted in the sheds of the Animal Nutrition Division of the Indian Veterinary Research Institute in 1988/89, eight adult Black Bengal goats were divided into two groups of four animals each. Animals in the control group were offered a conventional diet (concentrate and available roughage as per National Research Council standards) and those in the experimental group were fed exclusively on fresh leucaena foliage (young and newly developed leaves and shoots) for 300 days. Dry matter intake (DMI) and body weight of animals in the experimental group decreased in the first 6 weeks; daily DMI/lOOkg body weight was 306 ± 0·34kg in the control group and 2·40 ± 0·18 kg in the experimental group.There were significant differences in the apparent digestibilities of crude protein and nitrogen-free extractives; contents of digestible crude protein (DCP) and total digestible nutrients were 5·2 and 20·3%, respectively, in the controls and 65·6 and 59·1 %, respectively, in the experimental group. DCP intake was significantly higher in the experimental group as a result of high protein content in foliage but it was not well utilized.In the control and experimental groups, respectively, daily mean retention of nitrogen was 2·01±0·14 and 1·54±0·12 g/day, of calcium 1·60±0·08 and 2·92±1·69 g/day, and of phosphorus 1·12±0·25 and 0·24±0·07 g/day, the phosphorus balance being significantly lower in the experimental group. Blood calcium and serum glutamate oxaloacetate transaminase/serum glutamate pyruvate transaminase concentrations were statistically similar in both groups but the concentration of inorganic P was significantly lower in the blood of animals fed leucaena.

Abstract. Title of the Paper: Investigation on N-reduced feeding and use of free amino acids in fattening pigs The aim of the present study was to investigate the N-reduced feeding by fattening pigs feed by cereals rieh feedmixture supplemented with the free amino-acids L-lysine, DL-methionine, L-threonine, L-tryptophane, Lleucine, L-isoleucine, L-histidine and L-valine. It was to test extreme low crude protein content by requirement sufficient supply on amino-aeid. The reaction of the animals in growth, carcass quality and the reduction of Nexeretion was to investigate. The pigs were divided in two groups (control and experimental group) with 24 animals per group (12 females and 12 castrates). The experiment was divided into three periods (25–60, 60–85 and 85–110 kg body weight). The protein content of the feedmixture was by the control group 18.3, 15.6 and 13.6% and by the experimental group 14.0, 11.8 and 10.7%, respectively. The lysine-energy ratio of the feedmixture was by all three feeding periods by 0.72 or 0.74, 0.61 or 0.62 and 0.55 or 0.57 g lysine per MJ ME in control feedmixture or experimental feedmixture, respectively. By a high Performance are the average daily life weight gain (control group 869 and experimental group 863 g) and the lean meat rate (control group 55.2 and experimental group 55:0%) not influenced by the high of crude protein supply. The calculated N-excretion were by the control group 4.16 kg (as 100%) and by experimental group 2.60 kg (62.5%) per 100 kg body weight gain.

Abstract The purpose of the study was to increase the nutritional quality of pork, and to investigate the effect of the synbiotic on the oxidative stability of lipid. A 4 weeks experiment was performed on 8 weaned piglets (age 47 days, TOPIGS), divided into 2 groups (C, E). The control group (C) received a conventional diet, while the experimental group (E) included a diet supplemented with organic Zn and 10 g/kg synbiotic mixture. The productive parameters were evaluated. After slaughtered, muscle (tenderloin, shoulder, loin, ham and belly) and organs samples (liver, spleen and kidney) were collected. The muscle and organs samples were analysed regarding the proximate chemical analysis (dry matter, crude protein, crude fat, and ash). The antioxidant capacity and thiobarbituric acid reactive substances (TBARS) were performed on shoulder and ham samples at first day of the trial, 4 and 7 days after refrigeration. The crude fat determined in the loin samples, recorded a significant increase in the E group compared to the C group. The ash was higher in the shoulder samples from C group than in E group. At 7 days of refrigeration, the MDA concentration was significantly lower in the shoulder and ham samples from E group than those from C group. The conclusion was that the diet supplemented with organic Zn and 10 g/kg synbiotic mixture contributed to the delay of the lipid oxidation process of the shoulder and ham samples during the refrigeration period.

Abstract This study was conducted to determine the effects of a low-protein diet supplemented with synthetic amino acids on the biochemical parameters in the blood serum, the indicators of fermentation processes, and nitrogen excretion in 12 crossbred piglets. The piglets (weaned at 28 days of age) were divided into two groups with 6 piglets each. The control group had an initial average body weight of 8.8 ± 0.6 kg and the experimental group with an average initial body weight of 8.6 ± 0.7 kg. The control diet contained 210.8 g.kg−1 crude protein and the experimental diet contained 186.4 g.kg−1. The experimental diet was supplemented with lysine, methionine and threonine to achieve a more ideal amino acid pattern. The blood collections from the sinus ophthalmicus for the determination of the biochemical parameters were performed 4 times at weekly intervals in the control and experimental groups 4—5 hours after feeding. The faeces were taken from the rectum at the end of the study period. The decrease in the dietary crude protein content of the experimental group was manifested by a significant decrease of the blood urea level (2.61 mmol.l−1 average concentration) compared to the control groups (4.21 mmol.l−1 average concentration) (P < 0.001). The other serum component concentrations (total protein, albumin, glucose, cholesterol, total lipids and selected enzymes) showed no significant statistical changes between the control and experimental groups. The results of the fermentation process analysis indicated that the butyrate concentration decreased (P = 0.0017) and the pH increased (P = 0.0180) in the experimental group compared to the control group. The levels of crude protein and ammonia in the faeces of experimental animals were significantly lower (P < 0.001) in comparison with those in the control animals.

<b><i>Background:</i></b> Debate continues over whether or not individuals with low total water intake (TWI) are in a chronic fluid deficit (i.e., low total body water) [<xref ref-type="bibr" rid="ref1">1</xref>]. When women with habitually low TWI (1.6 ± 0.5 L/day) increased their fluid intake (3.5 ± 0.1 L/day) for 4 days 24-h urine osmolality decreased, but there was no change in body weight, a proxy for total body water (TBW) [<xref ref-type="bibr" rid="ref2">2</xref>]. In a small (<i>n</i> = 5) study of adult men, there were no observable changes in TBW, as measured by bioelectrical impedance, after increasing TWI for 4 weeks [<xref ref-type="bibr" rid="ref3">3</xref>]. However, body weight increased and salivary osmolality decreased indicating that the study may have been underpowered to detect changes in TBW. Further, no studies to date have measured changes in blood volume (BV) when TWI is increased. <b><i>Objectives:</i></b> Therefore, the purpose of this study was to identify individuals with habitually low fluid intake and determine if increasing TWI, for 14 days, resulted in changes in TBW or BV. <b><i>Methods:</i></b> In order to identify individuals with low TWI, 889 healthy adults were screened. Participants with a self-reported TWI less than 1.8 L/day (men) or 1.2 L/day (women), and a 24-h urine osmolality greater than 800 mOsm were included in the intervention phase of the study. For the intervention phase, 15 participants were assigned to the experimental group and 8 participants were assigned to the control group. The intervention period lasted for 14 days and consisted of 2 visits to our laboratory: one before the intervention (baseline) and 14 days into the intervention (14-day follow-up). At these visits, BV was measured using a CO-rebreathe procedure and deuterium oxide (D<sub>2</sub>O) was administered to measure TBW. Urine samples were collected immediately prior, and 3–8 h after the D<sub>2</sub>O dose to allow for equilibration. Prior to each visit, participants collected 24-h urine to measure 24-h hydration status. After the baseline visit, the experimental group increased their TWI to 3.7 L for males and 2.7 L for females in order to meet the current Institute of Medicine recommendations for TWI. <b><i>Results:</i></b> Twenty-four-hour urine osmolality decreased (−438.7 ± 362.1 mOsm; <i>p</i> &#x3c; 0.001) and urine volume increased (1,526 ± 869 mL; <i>p</i> &#x3c; 0.001) in the experimental group from baseline, while there were no differences in osmolality (−74.7 ± 572 mOsm; <i>p</i> = 0.45), or urine volume (−32 ± 1,376 mL; <i>p</i> = 0.89) in the control group. However, there were no changes in BV (Fig. <xref ref-type="fig" rid="f01">1</xref>a) or changes in TBW (Fig. <xref ref-type="fig" rid="f01">1</xref>b) in either group. <b><i>Conclusions:</i></b> Increasing fluid intake in individuals with habitually low TWI increases 24-h urine volume and decreases urine osmolality but does not result in changes in TBW or BV. These findings are in agreement with previous work indicating that TWI interventions lasting 3 days [<xref ref-type="bibr" rid="ref2">2</xref>] to 4 weeks [<xref ref-type="bibr" rid="ref3">3</xref>] do not result in changes in TBW. Current evidence would suggest that the benefits of increasing TWI are not related changes in TBW.

Purpose: to study the effect of ethanol on the parameters of THC, the percentage of granulocytes and total protein in the hemolymph of the Red claw crayfish (Cherax quadricarinatus).Materials and methods. The object of this experiment was 26 males of the Australian red-clawed crayfish (Cherax quadricarinatus) weighing from 23 to 83 g. The individuals were evenly divided into two experimental groups - with an injection of ethanol and a control group without an injection of 13 crayfish for each group. The injection dose was 2515 mg per 100 g of body weight. A day after the introduction of ethanol, hemolymph was taken with a syringe from the ventral sinus, the syringe was pre-washed with a 4% EDTA-Na2 solution. Three parameters were determined: the total hemocyte count (THC), percent granulocytes and percent total protein content. Counting of hemocytes and determination of granulocytes were performed in a Goryaev chamber under a light microscope. The total protein was determined by the refractometric method.Results. Differences in THC and total protein between the groups were statistically unreliable (p>0,05). THC in the experimental group is 36% more than in the control group. The total protein after the introduction of ethanol actually increased by 0,7%, and relatively by 14%. There were statistically different indicators of the proportion of granulocytes (p<0,05) - the average value of 33,1% in the experimental group versus 24,5% in the control group. A reliable (p<0,05) strong feedback was revealed between the total protein and the mass of individuals in both experimental groups, while in the experimental group there is a visible shift in the values of dependent hemolymph indicators towards an increase in smaller individuals.Conclusion. A single injection of ethyl alcohol with a dosage of 2515 mg per 100 g of body weight into the hemolymph of C. quadricarinatus does not cause significant changes in the THC and total protein after 24 hours. At the same time, the proportion of granulocytes actually increases by 9%, relative to 37%. This may indicate that granulocytes are involved in the formation of cancer defense mechanisms when exposed to toxic substances. The effect of different dosages of ethanol injections and the duration of its effect on hematological parameters requires additional consideration. It is necessary to investigate its effect on other indicators, such as the pH and buffer capacity of the hemolymph, the concentration of hemocyanin, glucose, lactates and calcium.

Context: Neuromuscular training enhances unconscious motor responses by stimulating both the afferent signals and central mechanisms responsible for dynamic joint control. Dynamic joint-control training is a vital component of injury-prevention programs. Objective: To investigate the effects of body-weight neuromuscular training on Y-Balance Test (YBT) performance and postural control in female basketball players. Design: Randomized controlled clinical trial. Setting: Basketball practice sessions. Patients or Other Participants: A total of 28 healthy elite female basketball players were randomly assigned to an experimental (n = 14) or a control group (n = 14). Intervention(s): Before their regular practice sessions, the experimental group warmed up with body-weight neuromuscular exercises and the control group with standard tactical-technical exercises twice weekly for 8 weeks. Main Outcome Measure(s): Anterior-, posteromedial-, and posterolateral-reach and composite YBT scores were measured before and after 8 weeks of training. Results: Improvement over baseline scores was noted in the posteromedial (right = 86.5 ± 4.5 cm versus 89.6 ± 2.2 cm, +3.5%, P = .049; left = 85.5 ± 4.3 cm versus 90.2 ± 2.7 cm, +5.5%, P = .038)- and posterolateral (right = 90.7 ± 3.6 cm versus 94.0 ± 2.7 cm, +3.6%, P = .016; left = 90.9 ± 3.5 cm versus 94.2 ± 2.6 cm, +3.6%, P = .011)-reach directions and in the composite YBT scores (right = 88.6% ± 3.2% versus 94.0% ± 1.8%, +5.4%, P = .0004; left = 89.2% ± 3.2% versus 94.5% ± 3.0%, +5.8%, P = .001) of the experimental group. No differences in anterior reach were detected in either group. Differences were noted in postintervention scores for posteromedial reach (right = 89.6 ± 2.2 cm versus 84.3 ± 4.4 cm, +4.1%, P = .005; left = 94.2 ± 2.6 cm versus 84.8 ± 4.4 cm, +10%, P = .003) and composite scores (right = 94.0% ± 1.8% versus 87.3% ± 2.0%, +7.1%, P = .003; left = 94.8% ± 3.0% versus 87.9% ± 3.4%, +7.3%, P &lt; .0001) between the experimental and control groups. Conclusions: Body-weight neuromuscular training improved postural control and lower limb stability in female basketball players as assessed with the YBT. Incorporating neuromuscular training into the workout routines for basketball players may enhance joint awareness and reduce the risk of lower extremity injury.

Abstract Objective. To investigate the application of carbon nanoparticles in lymph node dissection and parathyroid gland protection during thyroid cancer surgery. Subjects and Methods. Retrospective analysis was performed on 282 cases of thyroid cancer surgery in our hospital from 2018 to 2019. All patients underwent total thyroidectomy and cervical central lymph node dissection. Nanocarbon was not used in the control group, but was used in the experimental group. The general situation of the patients, the number of postoperative lymph nodes and the number of metastasis were collected, and the differences between serum parathyroid hormone and blood calcium were compared before and on the 3rd and 30th day after surgery. Results. There was no difference in age, sex and TNM stage between the two groups (P > 0.05). The number of metastatic lymph nodes in the experimental group (9.80 ± 4.80) was different from that in the control group (6.95 ± 3.86) (P < 0.05), and the number of metastatic lymph nodes in the experimental group was different from that in the control group (χ2 = 14.968, P < 0.05). There was no difference in blood calcium and PTH between the two groups before and at 3 and 30 days after surgery (P > 0. 05). Conclusion. The application of carbon nanoparticles in thyroid cancer surgery can significantly increase the number of lymph nodes seized and the positive rate of metastatic lymph node removal, but the protection of parathyroid gland is not obvious.

Among the most important issues of food safety, which conducted an extensive international discussion, is the use in livestock of drugs, such as recombinant bovine growth hormone, or somatotropin, and, in particular, ractopamine, stimulating the growth of cattle, pigs and poultry. Ractopamine is used in veterinary medicine to increase the meatiness of the carcass. Ractopamine improves feed conversion, reduces body fat through lipolysis and an intense muscle-building. In the United States, Australia, Argentina, Brazil, Canada and many other countries, ractopamine is allowed for usage as growth stimulator in livestock. However, in most countries of the European Union the use of ractopamine is forbidden. In this regard, it seems very important to develop effective and safe drugs that can stimulate the production of endogenous somatotropic hormone (STH). We propose to use for this purpose Gamavit – well-studied veterinary medicine stimulating metabolism and widely used by veterinary specialists in the Russian Federation, Ukraine, Belarus and some other countries. The aim of this work was to study the effect of Gamavit on STH production in suckling piglets and lambs. Previously it was shown elsewhere that Gamavit induced 2-fold increase in the STH blood level in calves. The experiment was done using 30 suckling piglets of Landrace breed at the age of 0 to 7 days and 10 newborn lambs of the Stavropol breed. All animals were kept in identical conditions, they were fed the same balanced diet. The study was conducted according to the following protocol: The piglets of the 1st group (control) received 0.9% NaCl solution at a dose of 0.5 ml/kg intramuscularly on the 1st, 2nd, 3rd and 5th days of the experiment. Piglets of group 2 (experimental) were inoculated with Gamavit at a dose of 0.5 ml/kg intramuscularly on the 1st, 2nd, 3rd and 5th days of the experiment. Lambs were inoculated with Gamavit at a dose of 0.5 ml/kg of body weight on 7th, 14th and 21st days after birth. Using method of enzyme immunoassay we shown that during the study level of STH in the experimental group of piglets inoculated with Gamavit gradually increased from 8.5 mIU/l before the experiment to 14.3 mIU/l on the 5th day. In the control group it ranged from 7.5 mIU/l to 10.2 mIU\l. At the end of the experiment greatest body weight gain was observed in the experimental group and amounted 45.450 g compared with 26,700 g in the control group piglets. In the experimental group of newborn lambs Gamavit induced raise in the STH serum level 2 from 6.5 mIU/l at day 0 to 13.1 mIU/l at day 21. Thus, Gamavit, unlike synthetic growth hormone, ractopamine and other beta-agonists used in livestock, induces the production of endogenous STH, which stimulates growth of the animal, while being safe and rapidly metabolizing on its own metabolic pathway.

Background: Ovulation induction with clomiphene citrate in women with infertility has been practiced more than 40% years but in infertile patients this treatment plan proved to be ineffective with multiple complication. Body weight plays an important role modulating reproductive development and functioning. Aim: To observe the effects on body weight of female albino rat after use of clomiphene citrate and letrozole for consecutive 1-4 estrous cycles Method: Eighty four adult female Albino rats were equally divided into three groups for this research. Body weight of each rat was measured before and after the experiment. Vaginal smear cytology of each rat was performed to study different phases of estrous cycle. Control group A was given normal saline orally , In Experimental group B rats were given letrozole (Femara) at dose 5mg/kg orally and in Experimental group C rats were given clomiphene citrate at dose 100ug/kg orally. Results: Significant weight gain is observed in rats taking clomiphene citrate as compared to letrozole Conclusion : Comiphene citrate directly affects the body weight which indirectly reduces the ovulation induction and pregnancy rate. Letrozole is good alternate for ovulation induction and for CC resistant patients. Keywords: Estrous cycle, body weight, citrate and letrozole
