Primary changes in the physiological status of animals can be traced in the deviation from the norm of indicators of a number of substances in biological fl uids, since biochemical indicators are a kind of indicator of processes occurring in the body. Having knowledge of hematological changes in the body of cattle, managers and specialists of livestock farms can manage the productivity and health of highly productive animals. The purpose of the research was to determine and analyze the biochemical parameters of the blood of cows in the dry period and at the increasing the milk yield when wet crushed corn grain was introduced into their ration. The research has been carried out on cows of Black-and-White breed in LLC “Agrofi rma “Urozhai” in the Zonal district in the Altai Territory. During the research the prevalence of productivity indicators of cows of the experimental group over analogues from the control group was proved. Thus average daily milk yield for the accounting period (60 days) it was 30,9 kg, which was 5,2 kg more than the control herdmates (P > 0,95). The total productivity of one head was 1541,57 kg of milk in the control group and 1854,69 kg in the experimental group, which was 313,12 kg more (P > 0,95). It has been found that most of the studied biochemical parameters corresponded to the physiological norm. The exception was the increased content of total protein in the blood of lactating cows of the experimental group 5 g/l above the upper limit of the norm (P > 0,999). A low albumin content in the blood of animals of the experimental group has been noted, and this indicator was signifi cantly lower than that in the control group by 3,45 g/l (P > 0,99). An excess of the physiological norm of globulin in the blood of animals of both groups has been found, the indicators of the experimental group signifi cantly exceeded the control group by 9,5 g/l (P > 0,99). There was a low level of chlorides after the increasing the milk yield 88,1 mmol/l in the control group and 89,2 mmol/l in the experimental group, then excess of manganese after the increasing the milk yield was 4,50 mmol/l in the control group and 8,14 mmol/l in the experimental group, which could be associated with the increased content of this element in feed and soil.

The health status of cows is evaluated and depending on haematological and biochemical profile of blood. Nutrition is the main technological factor that can produce profound changes in the metabolic profile in animals (Dhiman et al., 1991; Khaled et al., 1999; Ingvartsen, 2006). Blood parameters analyze can lead to identify if there are errors in nutrition of lactating cows (Payne et al., 1970). The aim of this study was the evaluation of metabolic and biochemical changes that occur during colostrum period and in terms of number of lactations in cows. The biological material was represented by a total of 60 heads of dairy cows from a family farm from Sălaj County, Romania. The cows are all from Holstein breed and presented no clinical signs of any specific pathology. Blood samples were collected from the jugular vein of each cow and analyzed. 10 individuals from each of the six lactations have been randomly selected. Haematological and biochemical parameters showed variations depending on factors analyzed here. In lactation 1 Hb was 7.55±3.05 (g/dl), while in lactation 6 the value was 12.5±2.10 (g/dl). RBC ranged as follows: in lactation 1 - 28.50±2.05 and in lactation 6 - 30.02±2.05. Lymphocytes varied within very wide limits under the influence of lactation: in lactation 1 - 2.8±1.56 and in lactation 6 - 7.55±1.80. The number of lactations and lactation rank have influenced blood biochemical and hematological parameters in dairy cows. Biochemical parameters are influenced by post-partum day, showing the lowest values in the early days of colostral period and the highest in the last few days of the same period.

The present study designed  to investigate the hematological and blood biochemical changes in pre and post lambing periods in Iraqi Nuaemie ewes. Ten Nuaemie ewes weighed 35-45 kg and aged between 2-3 years were reared in animal's house of Veterinary College / Tikrit University from October-2018 to March-2019, Ten ml of blood samples were collected from each animal during the periods of last gestation month, at lambing and 2 weeks thereafter, Two and half ml of blood samples were collected in EDTA- containing tubes to determine the hematological parameters and the remaining was used to separate serum and stored at -20 °c for blood biochemical assessment. The results   revealed decreased in total red blood cells, haemoglobin and packed cell volume during post lambing period. The total white blood cells count and neutrophils were decreased during the post-partum period, while the lymphocyte was decreased at the day of lambing (50±5.8%). The biochemical parameters exhibited lesser total protein concentrations at the day of lambing (6.5± 1.85 g/dl ) while greater glucose, cholesterol and triglyceride concentrations during post-partum period. The concentration of urea and creatinine increased during the pre-partum period whereas, LDL and HDL concentrations increased in post- lambing period. The minerals concentrations revealed lesser concentrations of Zink and iron during the post-partum period while, copper concentration was greater during similar period. In conclusion, the physiological status of animals have clearly effects on the haematological and biochemical parameters in Iraqi Nuaemie ewes.

Serum Biochemical

Physiological status-related changes in serum biochemical values are known to occur in many species. The aim of the current study was to evaluate total serum protein, albumin, glucose, calcium and phosphorus concentration and these parameters were measured by the serum analyzer for lactating (n=50) and non-lactating (n=50) dairy cattle in selected dairy farms of Chittagong district. The results (mean ± standard deviation) of the study showed that among serum biochemical parameters total protein (82.3 ± 2.15 gm/l), albumin (27.45 ± 5.06 gm/l), calcium (12.97±6.67 mg/dl) and phosphorus (7.26 ± 0.41 mg/dl) level in non-lactating cows were higher than the value of lactating cows as (81.28 ± 2.41 gm/l), (14.09 ± 2.05 gm/l), (10.05 ± 2.51 mg/dl) and (6.52 ± 0.30 mg/dl) respectively. Only glucose level in lactating cows (63.01 ± 6.67 mg/dl) was found higher than the non lactating cows (58.47 ± 3.84 mg/dl). In case of parity-wise parameters insignificant variation was noticed. It may be concluded that biochemical variation present between lactating cow and non lactating cow is important for interpretation of laboratory data and also for physiological diagnosis.Asian J.

The use of traditional corn silage in the diets of lactating cows during the winter-stall period leads not only to the animal productivity decrease, but also to the milk quality. An increase in these indicators can be achieved by improving the feed quality, in particular by using non-traditional crops for silage, amaranth being one of them. A comparative assessment of the effect of amaranth and corn silages on animal health, blood biochemical parameters, milk productivity and quality during the wintering period was carried out. Scientific and economic experience was conducted on the basis of peasant farm by I.I. Korovnikov, in Khokholsky district of the Voronezh region. Two variants of silage were put: from the green mass of amaranth to the phase of milk-wax ripeness of seeds and corn silo. Two groups of dairy cows of Holstein-Friesian breed with an average productivity of about 4200 kg of milk, selected by the principle of analogues, were used in the experiment. Body temperature, heart rate and number of respiratory movements per minute, scar reduction were within normal limits for cows of both groups. Moreover, a reliable difference in clinical and physiological parameters between the experimental and control groups was not found out both at the beginning and at the end of the experiment. The inclusion of high-protein amaranth silage in the diet of lactating cows leads to normalization of the liver and, as a result, normalization of all metabolic processes. Amaranth silage had a positive effect on the quality of milk. So the milk obtained from the cows of the experimental group had a significant advantage in comparison with the control one in terms of fat (by 0.46%) and protein (by 0.18%). Feeding amaranth silage to cows showed that it is well eaten by animals, and its use increases the productivity of cows by 11.9% compared with the contro group. The results obtained allow us to recommend amaranth silage as the main bulk feed in the winter-stall period when preparing balanced diets for lactating cows.

This paper presents the values of blood biochemical parameters of Simmental cows (n = 60), divided into five groups (dry cows, early puerperium, late puerperium, the fifth month of lactation, and cows with an extended service period). The ration for lactating cows contained an insufficient amount of dry matter, a third less than the lower limit of their requirements. In all examined groups of cows, a strong protein deficiency and excess calcium was found in the diet. Total protein concentration in all groups of cows were on the upper physiological limit, and the concentrations of bilirubin, carotene, vitamin A and total lipids were within the normal range. Low concentrations of urea in the third, fourth and fifth group of cows (3.1?0.39 mmol/l, 2.9?0.38 mmol/l and 3.3?0.43 mmol/l, respectively) indicate the imbalance of protein and energy in the diet. The presence of an energy deficit is also indicated by the low blood glucose in all groups of cows, especially the second and fifth groups of cows (2.2?0.04 mmol/l and 2.3?0.07 mmol/l, respectively). The unfavorable ratio of calcium and phosphorus in the diet resulted in the narrowing of the calcium:phosporus ratio in blood serum, which is particularly evident in cows with an extended service period (2.1?0.07 mmol/l compared to 1.9? 0.11 mmol/l). Based on these results,we conclude that the tested herd exhibits subclinical health disorders, caused by an inadequate diet and with adverse effects on the productive and reproductive parameters.

Dietary Treatments

Lysophospholipids (LPL), a new feed additive, were supplemented to a pelleted total mixed ration (TMR) of dairy cows to examine its effects on feed intake, production, and composition of milk and plasma biochemical parameters. Two dietary treatments included diets supplemented without (control diet; CON) or with LPL at a dose of 0.5 g/kg of pelleted TMR. Twelve multiparous, mid-lactation, Holstein cows (Bodyweight 730 ± 9.3 kg; 100 ± 6.0 days in milk) were randomly assigned to one of the two dietary treatments with a 42-day measurement period after a 14-day adaptation period. Feed and water were provided ad libitum. Feed intake and milk yields were recorded daily, blood samples were collected fortnightly, and milk samples weekly. The results showed that the supplementation of LPL did not change feed dry matter intake, milk yields, and milk composition. However, it increased total protein and globulin and the activity of alkaline phosphatase and decreased total cholesterol in plasma. This study suggests that LPL may have beneficent effects in animal health but might be not a feasible feed additive to increase production for dairy cows fed a pelleted TMR.
