Concentrações plasmáticas de cortisol, hormônios tiroídeanos, metabólitos lipídicos e temperatura corporal de cabras alpinas submetidas ao estresse térmico

The objective of this work was to determine the plasma concentrations of cortisol, thyroid hormone, lipids metabolites and corporal temperature or lactating Alpine goats submitted to heat stress. Six lactating Alpine goats were allotted randomly in a crossover experimental design for two groups: thermoneutral conditions or thermal stress. An adaptation period of 28 days was followed by Four-periods of 14 days each, when the animals submitted to thermal stress were exposed to the average temperature of 33.84 degrees C; THI of 86.20; BGT of 36.18 and BT of 32.11 degrees C from 8:00 am to 5:00 pm, including simulated solar radiation from 10:00 am to 3:00 pm. There were no differences between the groups in the plasma concentrations of cortisol, thyroid hormones (T-3-triiodothyronine and T-(4) tiroxine), and lipid metabolites (cholesterol and HDL). Rectal temperature was higher during thermal stress when compared to the group of animals in thermoneutral conditions. The goats maintained the thyroid plasma hormone concentrations, when exposed to repealed and intermittent stress, in spite of the occurrence of hypertermia during heat stress.

Concentrações séricas de progesterona e metabólitos lipídicos em cabras mestiças alimentadas com dietas hiperlipídicas durante o ciclo estral

The serum concentration of progesterone and lipidics metabolites were studied using tallow as lipidic suplementation during the estrous cycle of 32 crossbred goats, with average age and weight of five months and 25 kg. The goats were randomlly allocated in four treatments as described: treatment 1, restricted intake; treatment 2, full feed; treatments 3 and 4, hiperlipidics diets with 2.5% and 5.0% of tallow, respectively. The female goats under restricted intake, showed the small serum progesterone level (P<0.05) at 0, 3, 6, 9 and 12 days of the estrous cycle, while the ones under hiperlipidics diets, treatments 3 and 4, showed greater levels. The same results were found for serum levels of cholesterol and HDL in the estrous cycle days 6, 9 and 21, and 12, 15 and 21, respectively, that is, the females under restricted diet showed the small level and the ones treated with hiperlipidics diets, the highest. The hiperlipidics diets were important factor in altering the serum cholesterol and HDL levels, showing that the lipidic metabolism may be effective in cyclic luteal progesterone production in the puberal female goats.

Salmonelas e coliformes fecais em águas de bebida para animais

Sixty small farms of Botucatu County, S. Paulo, Brazil, given over to cattle breeding were studied. These farms account for 15% of the total of 402 farms that exist in the county. The sample was drawn by simple probabilistic technique. There were found to be one hundred and thirteen drinking places located on the farms. Samples of water were taken from these drinking places and examined for bacteria of the genus Salmonella, for the determination of Most Probable Number (MNP) of fecal coliform bacteria as well as determination of the water's pH. Water temperature was measured before collection. Samples from 15 drinking places (13.3%) were positive for Salmonella. The drinking places belonged to 12 of the sixty farms studied (20%). The following serotypes were identified: S. dublin, S. newport, S. madelia, S. IV 43:g,z57:-, S. saphra, S. glostrup, S. IV ochsenzool; S. I9,12:i:- and two new serotypes S. IV 41:z52:- and S. IV 50:d:-. Of the 113 samples studied 14 (12.4%) presented MPN/100ml of fecal coliforms above 4,000. There was no relationship between MPN/100ml of fecal coliforms above 4,000 and positivity for Salmonella. Highest positivity both for Salmonella and MPN/100mL of fecal coliforms over 4,000 occurred at temperatures above 18 degrees C. As regards pH, in both situations the highest positivity occurred between 6.0 and 7.0.
