SEGES Pig Research Centre tested three different types of supplementary air inlets in a farrowing house to evaluate the effect on the sows’ immediate environment during the summer. The three different types included trough valves, a single ceiling inlet per sow and transverse ceiling inlets in the section. No supplementary air inlets were installed in the control section. The primary parameters...

Seventy-two Friesian calves (BW = 102.0 +/- 1.8 kg) were bought from a commercial calf farm and distributed to a factorial arrangement of treatments in a complete block design with 3 treatments and 3 blocks of similar fasted BW to study the effect of increasing the number of feeding places per pen on performance, behavior, and welfare indicators during the 4 wk after arrival. Treatments consist...

We investigated the effects of forest fragmentation on bird assemblages in an Amazonian savannah landscape with forest fragments that have been isolated for more than 100 years. The study was conducted in areas surrounding the village of Alter do Chão (2°31'S, 55°00'W), Santarém, Brazil. Bird surveys and measurements of tree density were undertaken in 25 areas, with 19 plots in forest fragments...

Our objectives were to describe and test refined procedures for quantifying excreta produced from whole pens of dairy heifers. Previous research efforts attempting to make whole-pen measurements of excreta output have been complicated by the use of organic bedding, which requires cumbersome analytical techniques to quantify excreta apart from the bedding. Research pens equipped with sand-bedded...

A study was conducted to evaluate the effects of dietary levels of calcium (Ca), nonphytate P (NPP), phytase (Phy) and 25-hydroxycholecalciferol (25-OH) on live performance and bone development in male chicks fed a corn-based diet. Dietary treatments consisted of a 2×2×4×4 factorial arrangements with two levels of supplemental phytase (0 or 1200 FTU kg ), two levels of 25-OH (0 or 69 μg kg ), f...

A total of 320 pigs (DNA 241 × 600; initially 26.2 ± 0.48 lb BW) were used in a 21-d growth study to determine the available P (aP) release curve for Smizyme TS G5 2,500 (Barentz, Woodbury, MN). At approximately 19 d age, weaned, randomly allotted pens, and fed common starter diets. Pigs blocked by average pen body weight (BW) 1 8 dietary treatments on 18 post-weaning, considered 0 study. Dieta...

Abstract This study was to investigate the effects of dietary supplementation benzoic acid and sodium benzoate on growth performance nursery pigs. A total 432 pigs (6.9 ± 0.9 kg BW) were assigned 8 treatments (6 pigs/pen, n = 9) in a randomized complete block design with initial BW as fed for 41 d 3 phases (7/17/17 d, respectively). Treatments 1) basal diet (BD), 2) BD + antibiotic, 3) 0.30% be...

the present experiment was carried out to determine the effects of  antibiotic  growth promoters, blend of medicinal plants, prebiotic and organic acid on performance and nutrients apparent digestibility in a six week period, using one hundred ninety two one- day- old broiler chicks (cobb 500) on a randomized complete block design experiment with six treatments consisting of 4 replications and ...

The effects of ground flaxseed (FS) and a multicarbohydrase enzyme (C) supplement on piglet performance, gastrointestinal microbial activity, and nutrient digestibility were investigated in a 28-d trial. The enzyme supplement provided 500 units of pectinase, 50 units of cellulase, 400 units of mannanase, 1,200 units of xylanase, 450 units of glucanase, and 45 units of galactanase per kilogram o...
