The objective of this study was to use human held ketone meter for the estimation of β-hydroxybutyrate (ketone body) for the diagnosis of sub-clinical ketosis in goat. A total of 210 samples from pregnant and lactating doe in Guwahati, Assam and nearby area were collected in aseptic condition from the Jugular Vein. Goats having blood ketone level more than 0.4 mmol/l and glucose level less than 30 mg/dl were considered positive for sub-clinical ketosis. Total 24 goats were diagnosed subclinical ketotic.

The present study was undertaken with an objective to determine diurnal changes of the eye temperature of buffalo young bulls under different shelter management to determine the effect of heat stress. Twenty four buffalo bulls were randomly divided into two groups, each group comprising of 12 animals based on age (16–18 months) and body weight (Control = 301 ± 8.24 kg and Treatment = 311.45 ± 6.24 kg). The control group was housed under normal management practices followed, and the height of the shed was 10 ft. and width was 12 ft. with concrete floor. Whereas, the treatment group was housed in shed having 15 ft. height and 25 ft. width along with rubber mat as flooring and the total area provided for each animal in both the groups was 45.96 sq. feet. They were also provided with dairy fans and mist cooling in day time to ameliorate the heat stress. The thermal humidity index (THI), floor and roof temperature variation of the shed was recorded. The eye temperature of bulls was measured to evaluate the effect of different housing on the animals’ thermal status under hot dry summer conditions.Results revealed that the THI of treatment shed was significantly (P< 0.01) lower than the control at different times. The floor and roof surface temperature of the treatment shed was significantly (P<0.05) lower than the control shed. Diurnal patterns of eye temperature measured in both the groups showed increased eye temperature in control group bulls compared to treatment group. The eye temperature at 7.00 hrs was similar in both groups, whereas it was highly significant (P<0.01) at 13.00 and 19.00 hrs. The heat stress in the buffalo bulls was exhibited by increased eye temperature. Thus, the variation in the eye temperature can be effectively used as an indicator of heat stress and the dairy fans and mist cooling along with rubber mat flooring can be utilized to ameliorate the heat stress in the buffalo bulls.

The present study was conducted in 20 growing female Mehsana buffalo calves to study the effect of feeding cotton seed cake with the objective to increase growth and blood biochemical profile. Mehsana buffalo calves of 3-6 months of age were randomly divided in two groups on the basis of body weight and age. Group I was control (T1) fed Banasdan (concentrate mixture) whereas, group II (T2) was fed with cottonseed cake @ 700g, 850g and 960g for 1st, 2nd and 3rd month of treatment, respectively in addition to concentrate feed. Both the groups fed green fodder @ 3kg and dry fodder @ 1kg per day throughout the experiment. Body weights of individual calves were recorded at the commencement of the experiment and followed by monthly interval. Blood- biochemical constituents were recorded on day 1 and thereafter on day 90 of experiment period to analyze the changes in blood constituents in T1 and T2 groups. Average daily body weight gain of calves during the experimental period was higher (P less than 0.01) in T2 group as compared to T1 group. The serum glucose level was higher (P less than 0.05) in T1 group than T2 on day 90. The values of serum cholesterol, protein, globulin, ALP, SGOT and SGPT concentration were also significantly (P less than 0.01) higher in T2 group than T1 on day 90. However, the differences for serum albumin, A/G ratio, calcium and phosphorus on day 90 were found to be non-significant whereas metabolic hormone level T3 and T4 were significantly (P less than 0.01) higher in T2 than T1 on day 90. The results are indicative of supplementation of cotton seed cake in addition to Banasdan accelerated the growth, blood biochemical parameters and hormonal levels.
