To assess the acclimation of pigs to heat stress, the effects of high (33 degrees C) or thermoneutral (23 degrees C) constant temperatures on feeding behaviour and components of energy balance were studied in group-housed young pigs. Three groups of five pigs were used at each temperature. After 1 week of adaptation, voluntary feed intake (VFI) and heat production (HP) were recorded for thirtee...

BACKGROUND AND AIM In today era, broiler industry facing a problem of price hiking of feed of broiler, also in competitive era there should be lower feed cost, lower feed conversion ratio, low feed consumption yet good body weight at marketable age. MATERIALS AND METHODS Day-old commercial broiler chicks (n=200) were distributed randomly into 5 dietary treatment groups viz. control (T1), prob...

A study was conducted to determine 1) the effect of a dietary direct-fed microbial (DFM) on turkey poult performance, 2) the effect of a DFM on a Salmonella challenge, and 3) the effect of feed processing on the efficacy of the dietary DFM. Day-of-hatch Large White female poults were placed in 2 rooms in 2 Petersime batteries per room. Twelve pens of 7 birds each were used in each battery (24 p...

an experiment was conducted with two hundred and twenty day-old male broiler chicks (ross 308) in five groups to investigate the effects of different levels of 0, 0.2, 0.4 and 0.6% thyme extract in drinking water (including 27.4 mg sodium nitrate per liter) on broiler performance and antioxidantstatus and blood gas indices. no significant differences were observed between the treatments for bod...

the objective of the present study was to investigate the effects of high dietary levels of l-arginine during starter period on growth, intestine morphology and immune system of female ross broiler chicks. in this experiment, 192 day old female ross broiler chicks were fed with 4 dietary treatments in a completely randomized design, in which each dietary treatment included 4 replications. dieta...

A 1-year experiment was conducted to determine the role of the pineal gland in the seasonal sexual, antler development and feeding patterns of deer. Three mature male whitetailed deer were pinealectomized. These animals along with four normal bucks were housed in individual outdoor pens. Blood samples were drawn bi-weekly and analyzed for calcium and phosphorus, alkaline phosphatase, and total ...

We investigated the variation in eating speed by individual pregnant sows and the influence of feeding dry compared to wet feed. A total of 39 Norwegian Landrace × Yorkshire dry sows, 13 primiparous and 26 multiparous, were included in the experiment. In experimental period 1, each sow was offered 2.2 kg of a standard concentrate feed without added water. In experimental period 2, the sows were...
