SUMMARY The work was conducted to evaluate the metabolic profile of lactating goats fed diets containing integral mango meal as a replacement for corn. Four levels of replacement (0, 33, 66 and 100%) were evaluated in diets with forage:concentrate ratio of 60:40. Eight crossbred multiparous lactating Saanen goats (48.72 ± 1.99 kg of BW) were introduced in the experiment 48 days postpartum and maintained up to 124 days of lactation. It was used a double Latin Square (4x4) experimental design, with four treatments, four periods and four animals per square. There was no effects (P>0.05) for the integral mango meal level on the intake of DM (1890 g/day), CP (278 g/day) and NDF (959 g/day). However, the intake of NFC and TDN decreased (P<0.05) 27.9 g/day and 0.082 kg/day, respectively, as the dietary integral mango meal increased. The concentrations of urea, creatinine, gamma glutamyl transferase, aspartate aminotransferase, albumin, total protein, glucose, triglycerides, total cholesterol, and magnesium were not altered (P>0.05) by replacement levels, with average values of 54.52 mg/dl, 0.71 mg/dl, 52.59 UI, 77.37 UI, 4.69 g/dl, 9.32 g/dl, 74.44 mg/dl, 40.10 mg/dl, 39.39 mg/dl, and 11.09 mg/dl, respectively. Considering the metabolic profile, mango meal whole can totally replace corn in diets of dairy goats.

In order to differentiate groups of hypocalcemic (G1) and normocalcemic animals (G2) and infer the influence of subclinical hypocalcemia on metabolic profiles, this study determined calcium concentrations during the transitional period in 35 dairy goats healthy, pregnant, primiparous or multiparous, crossbreed or pure-bred dairy goats producing average 3 kg/day/goat. Therefore, blood samples were collected before (30, 20 and 10 days before parturition), on the day of delivery and after parturition (10, 20, 30, 40, 50 and 60 days postpartum). The variables measured were glucose, nonesterified fatty acids, β-hydroxybutyrate, cholesterol, triglycerides, amylase, total protein, albumin, urea, creatinine, aspartate aminotransferase, gamma glutamyl transferase, creatine kinase, total calcium, phosphorus, magnesium, chlorides, cortisol and insulin, as well as ionized calcium (Ca++), sodium and potassium. Goats were considered to have subclinical hypocalcemia if Ca++ ≤0.72 mmol/L. The data were analyzed by ANOVA. In subclinically hypocalcemic goats, serum concentrations of Ca++ decreased earlier (10dbp) than in normocalcemic goats (parturition) and remained lower throughout the transitional period (p=0,004). Among the measured variables, Ca++ showed greater influence on the NEFA, glucose, insulin and total calcium but also influenced the protein profile. Lower food intake by goats with subclinical hypocalcemia was one of the main factors interfering with the metabolic profile and likely the productivity of these animals. Studies should be conducted to measure the effects of subclinical disease on the production rates and on the emergence of other transitional period diseases.

The objective of this trial was to evaluate the effect of the partial replacement of corn by forage cactus (Nopalea cochenillifera Salm Dyck) in the diets of lactating goats on the nutrient intake, milk production and composition and ingestive behavior. Five crossbreed Saanen x Pardo Alpina goats with body weights of 47 ± 3.3 kg were used in the study. The design was 5x5 Latin square design, in which the treatments were as follows: 20, 25, 30, 35 and 40% of girl cactus included in the diet as a partial replacement of corn, with 0, 18, 36, 54 and 72% of the added the cactus comprising of gliricidia (Gliricidia sepium (Jacq) Walp) as roughage in all treatments. Treatment did not affect (P > 0.05) the dry matter intake, crude protein, neutral detergent fiber, acid detergent fiber and total digestible nutrients with the increasing levels of cactus in the diet, presenting means of 1.64, 0.26, 0.82, 0.54 and 1.17 kg day-1, respectively. In the same way, no influence was observed on the daily milk production and levels of fat, protein, lactose and total solids of milk, which averaged 1.18 kg day-1; 3.74, 3.34, 5.06 and 13.56%, respectively. The inclusion of cactus also had no influence (P > 0.05) on the ingestion behavior. The treatment with 35% cactus showed a lower impairment of food intake (31%). The partial replacement of the corn by the girl cactus in the diets of dairy goats can be accomplished because it does not alter the intake, milk yield and composition and feeding behavior. The replacement of up to 54% corn by the cactus is recommended to reduce producer costs for food.

AbstractThe aim of this study was to evaluate the effects of the hot season and nutrition on the oxidative status and metabolic profile of lactating goats during mid lactation. Twenty-four Red Syrian goats were allocated into three groups that were offered the following diets: natural pasture (P), pasture+500 g/h per day of concentrate (PC) and hay plus 500 g/h per day of concentrate (HC). Blood samples were taken in spring (85±7 days in milk (DIM)) and summer (120±7 DIM) and assayed for reactive oxygen metabolites (ROMs), α-tocopherol, glucose, triglycerides, cholesterol, non-esterified fatty acids, total protein, albumin and globulin concentrations and glutathione peroxidase (GHS-Px) and superoxide dismutase (SOD) activities. Milk yield and milk composition were also measured. SOD, GSH-Px and ROMs levels increased during summer when temperature humidity index values were high. The increase in ROMs in the PC and HC groups could be ascribed to the improved nutritional regime and to their higher production level. The markers of the oxidative status and of the metabolic profile measured in this study indicate that goats may have experienced moderate oxidative stress. It seems that, seasonal rather than nutritional factors have a more pronounced effect on oxidative status markers. Concentrate supplementation sustained milk yield and may represent a useful means to extend the lactation period in dairy goats during late spring and summer.

Abstarct. The aim of the present investigation was to evaluate the effects of aflatoxin B1 and Mycotox NG applied either independently or together, on blood total protein, albumin, blood glucose, total bilirubin, triglycerides, cholesterol, enzyme activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (AP), gamma-glutamyl transferase (γ GT), lactate dehydrogenase (LDH) and changes in liver morphology. At the same time, the potential of supplementation of feed with a mycosorbent (Mycotox NG) was evaluated. Experiments were carried out with 40 1-day-old Toulouse geese from mixed sexes divided into one control and three treatment groups (n=10). Groups were as followed: Group I – control (0 mg/kg AFB1 not supplemented with Mycotox NG); Group II (0.5 g/kg Mycotox NG), Group III (0.5 mg/kg AFB1) and Group IV (0.5 mg/kg AFB1 and 0.5 g/kg Mycotox NG). In this study, commercially available geese of Toulouse strain were reared from day one to forty two days in the deep litter system of management and the birds were divided into four groups. Normal feed tested free of aflatoxin (AFB1), was given to the control (Group – 1). 0.5 g/kg Mycotox was supplemented with the feed to Group 2, Aflatoxin (0.5 mg/kg feed) was supplemented with the feed to Group 3 and Mycotox Ng (0.5 g/kg feed) + 0.5 mg/kg feed AFB1 was supplemented with the feed to Group 4. The duration of the experiments was 42 days. The monitored blood chemical parameters were analysed on post treatment days 21 and 42. In birds treated only with AFB1, (group III) increased blood activities of studied enzymes. At the same time, blood total protein, albumin, cholesterol, glucose and triglycerides were reduced as compared to controls. The observed histopathological changes in the liver consisted in various extent of dystrophy (congestion, vacuolar and granular dystrophy, round cell proliferation, necrobiotic changes, hyperplasia of gallbladder epithelium). The addition of mycosorbent (Mycotox NG) to the feed of Groups IV reduced substantially the changes in blood chemistry and the severity and frequency of liver histological lesions. The addition of mycosorbent (Mycotox NG) to the feed of Groups IV reduced substantially the changes in blood chemistry and the severity and frequency of liver histological lesions.

The present study was carried out to examine the physical, microscopical and biochemical parameters of the synovial fluid from the carpal joints of donkeys suffering from Strongylus spp. and Parascaris equorum infestation. Forty-five donkeys were selected out from a total of sixty animals based on faecal analysis. Animals were divided into 3 groups, which included Strongylus spp. (n=23), mixed infestation (n=17, Strongylus spp. and Parascaris equorum) and control (n=5) groups. The aspirated synovial fluid from all animals (n=45) was examined physically and microscopically. Then, the total protein, albumin, globulins, calcium, phosphorus, magnesium, glucose levels, and gamma glutamyl transferase (GGT) and alkaline phosphatase (ALP) activities were measured in the serum and synovial fluid of all animals. The results revealed no changes of the physical and microscopical features of the synovial fluid of the infested and control animals but there were significant decreases in total protein, albumin, globulin, glucose and magnesium levels in the serum of Strongylus and mixed infection groups. The synovial fluid analysis exhibited an increase of calcium and phosphorus levels, and ALP activity, and decreased levels of total protein, glucose and GGT in Strongylus and mixed groups. The results of this study suggested significant changes in some biochemical parameters in both serum and synovial fluids in donkeys suffering from parasitic infestation.

Artemisia abyssinica leaves, a traditional medicine for the treatment of various disorders, were fed to male Wistar rats at 2% and 10% of the standard diet for 6 weeks. A 2% A. abyssinica leaf diet was not toxic to rats. Depression in growth, hepatopathy and nephropathy were observed in rats fed a diet containing 10% of A. abyssinica leaves. These findings were accompanied by leukopenia, anaemia and alterations of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) and gamma glutamyl transferase (GGT) activities with changes in concentrations of total protein, albumin, cholesterol and urea.

Abstract Provision of good quality colostrum is essential for the passive immunity and nutrition of newborn calves. In order to better predict the quality of colostrum and the transfer of passive immunity, the relationships between colostrum components and between calf serum components were examined in this study. Samples of bulk tank milk, colostrum pooled from several cows 0–4 d postpartum, and colostrum collected from individual cows twice daily for 3 d post-partum were compared. With the exception of fat percentage, there were strong correlations between the levels of the components in the pooled colostrum and in the individual cow colostrum collected 0–1 d postpartum. The correlations between total solids as measured by Brix refractometry and total protein, immunoglobulin G (IgG), lactose % and protein % in colostrum within 1 d postpartum and pooled colostrum were 0.92, 0.90, −0.88 and 0.98, respectively. These high correlations enabled these colostrum components to be accurately predicted from Brix % and therefore, the volume of colostrum required to feed neonate calves can be optimised based on Brix refractometry to avoid failure of passive immunity transfer. To assess whether the components obtained from colostrum were correlated in calf blood, newborn calves were separated from their dams before suckling and blood sampled before feeding (day 0), and on days 1 and 7, after receiving colostrum or milk twice a day. The correlations between glucose, total protein, IgG, and gamma-glutamyl transferase (GGT) levels in the calf blood were lower than the correlations observed between the colostrum components. The highest correlation was between serum protein measured by refractometer and serum IgG within one week postpartum. GGT activity was not a good indicator of serum IgG levels. However, serum protein refractometer measurements predicted serum IgG level with high accuracy, providing an on-farm test to determine that calves have received sufficient passive immunity and colostrum components.

Aim: This study was conducted to evaluate the possible association between values of certain serum biochemical parameters and seropositivity against Anaplasma marginale in dairy cows. Materials and Methods: Serum samples from 60 seropositive and 40 seronegative cows were used to determine the values of beta-hydroxybutyrate (BHB), glucose, creatinine, blood urea nitrogen, total protein, albumin, alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine transaminase (ALT), lactate dehydrogenase (LDH), and gamma-glutamyl transferase (GGT) using commercially available kits and reagents. The serostatus of cows against A. marginale was determined using a commercially available cellular enzyme-linked immunosorbent assay kit according to the manufacturer's recommendations. Significant differences in serum biochemical values between seropositive and seronegative groups were evaluated using independent Student's t-test. Possible associations between the serostatus of the cows and different biochemical parameters were evaluated using univariate followed by multivariate logistic regression analyses. Results: There was a statistically significant increase (p≤0.05) in values of total protein, BHB, LDH, and AST in seropositive cows compared to seronegative cows while a non-significant increase in values of ALP, ALT, and GGT was detected in seropositive cows. A strong correlation (R=0.69) between serum levels of BHB, LDH, and AST and seropositivity against A. marginale was detected. Conclusion: There is evidence of a possible association between A. marginale infection and liver damage/hepatic fatty degeneration in dairy cows. Further studies, however, are required to elucidate the exact pathophysiological mechanisms of this relationship.

Physiological Variations

This study aimed to evaluate the physiological variations in the serum biochemical profile of neonate (3-5 days old) Senepol and crossbreed Holstein x Gir calves in Uberlândia, state of Minas Gerais, Brazil, and to compare values between breeds and sexes. In total, 168 healthy Senepol (n = 80, 28 females and 52 males) and crossbred Holstein x Gir (n = 88, 49 females and 39 males) calves were evaluated. From each animal, approximately 5 mL of blood was collected by jugular venipuncture into a sterile tube without anticoagulant to obtain serum. Serum concentrations of total protein, albumin, creatinine, urea, total cholesterol, triglycerides, calcium, and phosphorus; and the activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, and gamma-glutamyl transferase (GGT) were determined on a automated multichannel analyzer. There were significant differences (p &lt; 0.05) in serum concentrations for total protein, globulin, albumin/globulin ratio (A:G), creatinine, urea, phosphorus, calcium/phosphorus ratio (Ca:P), AST, and GGT between Senepol calves and crossbred Holstein x Gir calves, but no significant differences in serum concentrations were observed between male and female calves for either breed (p &gt; 0.05). It was concluded that the serum biochemistry profile of newborn Senepol and crossbred Holstein x Gir calves was affected by differences in colostrum intake management and breed characteristics. Also, no differences in blood parameters were observed between male and female calves.
