background and objectives: the purpose of the present study was to investigate effects of various heat shock conditions and fast freezing and subsequent thawing on the viability and recovery of bacillus coagulans and bacillus subtilis as probiotic sporeformers, and also to compare spore plate and microscopic counts. materials and methods: after preparing the final suspensions of b. coagulans an...

This experiment was conducted to examine the effect of dietary supplement with green Brazilian propolis on body weight (BW), weight gain (BWG) and cecal microflora in broiler chickens raised under heat stress condition. A total of 504 15-d-old male broiler chickens (Ross 708) were randomly allocated to 6 treatments, each with 4 replicate pens per treatment, 21 chickens per pen from hatch to 42 ...

In the present study, the relationship between the temperature-humidity index (THI) and the incidence of medical treatments in lactating dairy cows in Lower Saxony, Germany, was investigated. Records of all veterinary-treated cases over 2 years (2003 and 2005) from eight Holstein-Friesian dairy herds raised in loose-housing systems (55 to 170 cows per herd) were evaluated. After exclusion of ma...

Forty-two individually housed entire male pigs weighing 37.5 ± 0.15 kg (mean ± SEM) were used in a randomized block design having 7 dietary treatments (n = 6). The dietary treatments were 5 semisynthetic diets containing 350 g/kg of soybean (Glycine max) meal (SBM) with variable heat treatments (0, 7, 14, 21, and 28 min autoclaved at 135°C), a protein free (N-free) diet, and an enzymatically hy...

BACKGROUND Heat stress adversely affects the physiological and metabolic status, and the productive performance of buffalo. METHODS The present study was conducted to explicate the effect of misting and wallowing cooling strategies during heat stress in lactating Murrah buffalo. The study was conducted for three months (May-July) of which first two months were hot dry and last month was hot h...
