A study was carried out to determine the epidemiology of gastrointestinal nematodes in indigenous Tuli cattle and the effect of dietary protein supplementation and anthelmintic treatment on productivity in young growing cattle. Forty steers with an average age of 18 months were divided into 4 groups; 1) fenbendazole (slow release bolus) and cottonseed meal (FCSM group), 2) fenbendazole (FBZ group), 3) cottonseed meal (CSM group) and 4) control (no cottonseed meal and no fenbendazole) (control group). Performance parameters measured included wormeggs per gram of faeces (EPG), packed cell volume (PCV), albumin and live-weight gain. Results showed that faecal worm egg counts were lower and PCV was higher in the FCSM and FBZ groups than in the CSM and control groups (P < 0.01). Weight gains were higher in the CSMand FCSM groups than in the FBZ and control groups (P < 0.05). The cost benefits of anthelmintic treatment and dietary supplementation were apparent in this study. The improved growth performance of the FCSM, FBZ and CSM groups reflected a financial gain over the controls on termination of the study. The dominant genera of gastrointestinal nematodes on faecal culture, pasture larval counts and necropsy were Cooperia and Haemonchus. The incidences of Trichostrongylus, Oesophagostomum and Bunostomum were low.

The purpose of the research is studying the efficacy of Eprimek (Eprinomectin) against gastrointestinal nematodes in sheep.Materials and methods. A commercial experiment to study the antiparasitic efficacy of Eprimek was carried out in June 2020 on 300 lambs of the North Caucasian breed in a private flock of Filimonovskaya Village, Izobilnensky District, the Stavropol Territory, which were divided into two groups. The experimental group of lambs (290 animals) was injected Eprimek subcutaneously at the earset at a dose of 1 ml/50 kg of live weight (10 mg of Eprinomectin in 1 ml), and 10 lambs were not treated; they were used as control. We collected feces from the lambs of the experimental and control groups before administration of the drugs and after 15 and 30 days. Fecal samples were examined by the flotation technique with a saturated solution of ammonium nitrate with counting nematode eggs in 1 g of feces. The results were processed statistically.Results and discussion. Eprimek showed a decrease in the number of excreted helminth eggs from 225.1±28.2 to 4.1±2.3 in production environment at a dose of 1 ml/50 kg of live weight, according to coprological studies on the 15th day after treatment in the experimental group of lambs. The efficacy was 98.2%, and 70% of the animals were free from the infection. The intensity of infection of the control lambs by gastrointestinal nematodes was 131–151 eggs per 1 g of feces at 100% prevalence.

Изучение влияния пробиотического препарата ЭМ-курунга на приросты, анализы крови и помёта птиц проведено на примере цыплят техасских белых перепелов. В качестве объекта исследований использовались цыплята перепелов, начиная с суточного возраста. Средняя масса цыплят на начало эксперимента составила 9,2±0,12 г. Цыплят забивали в возрасте 90 суток. Установлено, что введение в рацион цыплят пробиотического препарата ЭМ-курунга в количестве 0,2 мл на 1 кг живого веса увеличивает сохранность молодняка на 14,8% и приросты птенцов – на 10%. Сравнительный анализ биохимических данных опытной и контрольной групп птицы показал, что введение в рацион опытной группы пробиотика практически не повлияло на белковый обмен. Общий белок у опытной птицы был недостоверно меньше, по сравнению с контролем, на 1,25%, та же картина наблюдалась по уровню альбуминов – меньше на 1,9%, глобулинов – на 1%. Сравнительный анализ показателя кислотности кала птиц опытной и контрольной групп показал достоверное различие. Так, у контрольной группы рН кала имел среднее значение 6,5, у перепелов опытной группы – 7,5. Таким образом, у опытной птицы, в сравнении с контрольной, активная кислотность кишечного содержимого достоверно сдвинулась в слабощелочную сторону, что свидетельствует о благоприятном воздействии пробиотика на микрофлору желудочно-кишечного тракта перепелов, снижая уровень патогенной микрофлоры, активно развивающейся в кислой среде. The study of the effect of the probiotic preparation EM-Kurunga on gains, blood tests and poultry litter was carried out using the example of White Texas quail chickens. Quail chickens starting at daily age were used as the subject of research. The average weight of chickens at the beginning of the experiment was 9.2±0.12 g. Chickens were slaughtered at the age of 90 days. It was established that the introduction of the probiotic preparation EM-Kurunga into the diet of chickens in the amount of 0.2 ml per 1 kg of live weight increases the safety of young animals by 14.8% and the gains of poults – by 10%. A comparative analysis of the biochemical data of the experimental and control groups of poultry showed that the introduction of the probiotic into the diet of the experimental group had practically no effect on protein metabolism. The total protein in the experimental poultry was insignificantly less than in the control by 1.25%, the same pattern was observed in the level of albumin – less by 1.9%, globulins – by 1%. Comparative analysis of the acidity index of poultry feces from the experimental and control groups showed a significant difference. So, in the control group the pH of feces had an average value of 6.5, in the quails of the experimental group – 7.5. Thus, in the experimental poultry in comparison with the control one the active acidity of the intestinal contents significantly shifted to the slightly alkaline side, which indicates a favorable effect of the probiotic on the microbiota of the quail gastrointestinal tract, reducing the level of pathogenic microflora actively developing in an acidic condition.

Moxidectin administered in January or February at a single dose was tested for efficacy in horses on two farms for 12 and 11 months, respectively. Horses were infected with cyathostomes naturally in the previous grazing period. Forty horses of farm 1 and 20 horses of farm 2 were used in controlled tests to evaluate the efficacy of moxidectin 2% gel formulation at the dosage 0.4 mg moxidectin per kg of live weight, ivermectin commercial paste formulation at the dosage 0.2 mg ivermectin per kg of live weight, mebendazole and fenbendazole commercial paste formulation at the dosage both 7.5 mg mebendazole and fenbendazole per kg of live weight, all applied orally. Three control groups of 10 horses each (farm 1) were treated twice a year with ivermectin and benzimidazoles, respectively. Individual faecal egg counts, faecal cultures and larval differentiation were performed. Moxidectin had more prolonged and greater suppressive effects on the post-treatment reappearance and magnitude of strongyle egg counts than did ivermectin or benzimidazoles. In the moxidectin treated group (M1) strongyle eggs were seen for the first time in April and a slight increase in the mean count of eggs per gram of faeces (EPG) was observed during the rest of the season. Litter larval counts significantly reflected levels of exposure during the tested season. Twenty animals of farm 2 were allocated into two groups of ten horses each based on pre-treatment eggs per gram (EPG) counts (moxidectin treated group and control group). In the moxidectin treated group mean egg counts remained very low throughout the study. A plateau was reached by autumn, with egg counts ranging from 74 to 145 EPG. The faecal egg counts of moxidectin treated group (M2) were significantly higher in March, April, May and June.

6 heifers of 4—9 months suffering from indigestion were given oat meal containing 80 mg of Aureomycin for 43 days. 6 similar heifers, serving as controls, were kept on the same diet and in the same shed. The average daily additional growth of the group receiving aureomycin was 285 g; the corresponding additional growth of the control groups was 108 g. The average increases for the test and control group, respectively, were: live weight 14.45 kg/6.48 kg, length 9.33 cm/3.33 cm, chest circumference 6.50 cm/4.33 cm, height of withers 1.8 cm/1.2 cm, pelvic breadth at the tubera coxae 1.7 cm/0.7 cm. Serum calcium and copper fell and potassium rose in the material as a whole. There were no statistically significant differences between the test and control groups except in Na, which rose in the test and fell the control groups. In view of the small size of each group and the nevertheless nearly significant difference in average weights (0.05 < P < 0.1), it would seem that aureomycin additive in the feed was beneficial for the heifers in these conditions. Economic consiferations will decide whether it is generally advisable to resort to aureomycin additive. The blood changes were regarded as being due to the transfer of the animals from the cold winter air indoors to a warm shed.

A feeding trial was conducted on 21 crossbred (Local×Friesian, Local×Sahiwal, Sahiwal×Friesian) calves of around one week age for a period of 70 days with the objective of evaluating effects of probiotic on growth performances of calves. Calves were selected and distributed equally into three groups maintaining equal sex ratio in each group, namely the farm practice (FP), control and probiotic groups. The calves were fed on milk as 12% of their live weight up to 14 days and then 10% milk of their live weight up to 70 days of age and wheat bran was supplied to the calves from 50th day at the rate of 250g/calf. The calves of probiotic group werefedaprobiotic mixture containing lactic acid bacteria (LAB) at 0.5 g /d. The data of feed intake and growth for all groups were recorded up to 35 days and then up to 70 days for probiotic and control groups. The calves under probiotic group were achieved 82.8% and 74.5% higher gain (P<0.05) than that of FP and control group, respectively and feed conversion ratio was observed significantly (P<0.05) better in probiotic group (1.83) than that in FP (3.41) and the control group (3.50) up to 35 days of trial. However, no significant differences were found in average live weight gain and feed conversion ratio between probiotic and the control groups (1.99 vs 2.07, respectively) up to 70 days of the trial. Average counts of E. coli were lower in probiotic group than that in the control and FP. The incidence of diarrhoea in probiotic fed group was found 3 and 13 times lower compared to FP and the control group, respectively. Bangladesh J. of Livestock Res. 21-25: 89-102, 2018

The article presents the results of research on the use of linear sheep of edilbaevsky, saryarkinsky and Kazakh short-tailed semi-coarse breeds on the uterus of the non-tribal part of the herds in order to improve their meat productivity. The research was conducted on farms in West Kazakhstan and Karaganda regions. The average live weight of linear rams used in the experimental group of Queens and producers of the control group was 114 and 102 kg for the edilbaev breed, 99 and 93 kg for the saryarkin breed, and 95 and 91.5 kg for the Kazakh short – tailed semi – rough – haired breed. The average live weight of Queens of the experimental and control groups: 62.4 and 62.6; 57.4 and 57.2 kg and 53.2-53.0 kg. The results of research showed that in all variants of selection, the descendants of linear rams are born larger and become highly reliable by 4-4,5 and 16-18 months of age. The rate of meat production per uterus at the time of lambs weaning was 36.5-41.5 kg in the linear rams groups, or 5.2-5.7% higher than in the non-linear producers groups. When carrying out control slaughters of rams in 4 and 16 months. in terms of age, both in terms of slaughter indicators and meat qualities, the advantage was on the side of linear rams.The use of linear rams on the uterus of the non-tribal part of the sheep herds of edilbaevsky, saryarkinsky and Kazakh short-tailed semi-coarse breeds contributed to the production of young animals with a higher intensity and energy of growth in comparison with off spring from non-linear producers, which provided higher production of meat per uterus.

Conjugated linoleic acid (CLA) is a collective term for the positional and geometric isomers of a conjugated diene of linoleic acid (C18:2, n-6). The aims of the present study were to evaluate whether levels of hepatic α-tocopherol, α-tocopherol transfer protein (α-TTP), and antioxidant enzymes in mice were affected by a CLA-supplemented diet. C57BL/6 J mice were divided into the CLA and control groups, which were fed, respectively, a 5 % fat diet with or without 1 g/100 g of CLA (1:1 mixture of cis-9, trans-11 and trans-10, cis-12) for four weeks. α-Tocopherol levels in plasma and liver were significantly higher in the CLA group than in the control group. Liver α-TTP levels were also significantly increased in the CLA group, the α-TTP/β-actin ratio being 2.5-fold higher than that in control mice (p<0.01). Thiobarbituric acid-reactive substances were significantly decreased in the CLA group (p<0.01). There were no significant differences between the two groups in levels of three antioxidant enzymes (superoxide dismutase, glutathione peroxidase, and catalase). The accumulation of liver α-tocopherol seen with the CLA diet can be attributed to the antioxidant potential of CLA and the ability of α-TTP induction. The lack of changes in antioxidant enzyme protein levels and the reduced lipid peroxidation in the liver of CLA mice are due to α-tocopherol accumulation.
