Current research studied the effect of partial replacing corn by glycerin and essential oils addition in diet Nellore bulls finished feedlot on feed intake, animal performance three markers were assessed to estimate apparent digestibility. Thirty with average weight 400 ± 34.1 kg 22 2 months old housed collective pens (10 x 20 m2) for 63 days. The randomly assigned 3 diets per treatment): CON – Control (without or Essential® oils); GLY Glycerin (15% dry matter - DM); GEO DM) (3 g day-1)....

Current study aimed to evaluate the performance of bulls (1/2 Purunã vs 1/2 Canchim) slaughtered at two ages and three different weights. One hundred thirteen were divided into slaughter (16 22 months) weights (light, 422 kg; medium, 470 heavy, 550 kg). The body weight was higher for 16 months. Daily gain, carcass dressing Feed intake months although feed efficiency better Carcass characteristics percentages muscle, fat bone meat similar between ages. animal lower lighter animals. conversion...

Intensive systems of milk production in Brazil and Holland are compared by SWOT analysis. Twenty-one farms, 10 Wageningen, central region Holland, 11 Castro, central-eastern the state Paraná, Brazil, were sampled. Data retrieved from semi-structured interviews with owners or people responsible for dairy activities, using a questionnaire guide digital recorder. After results analysed, table was elaborated representing strengths, weaknesses, opportunities risks each country. Dairy farms...

Chronic kidney disease (CKD) is one of the most common diseases in cats, with an estimated prevalence 1.6 to 20%. The affected cats are elderly over 12 years age. It has a progressive nature and irreversibly affects function. There several factors that can end up predisposing this disease, such as low water intake excessive consumption dry food but, time, it not possible establish origin problem. Clinical signs nonspecific diagnosis made based on clinical history, physical examination...

This study aimed to evaluate the effects of diets composed cottonseed hull on feed intake, in vitro digestibility, animal performance, carcass characteristics and ingestive behaviour young bulls (1/2 Simmental × 1/2 Nellore) fed a high-concentrate system. Thirty crossbred (319 ± 12.5 kg bodyweight, 11 0.8 months old) were assigned complete randomised experimental design three (CH21: 210 g/kg DM, basis; CH27: 270 DM CH33: 330 basis) with 10 animals per group. The kept feedlot for 162 days....

Pasture-feeding in lambs has been associated with dark-coloured meat and high contents of volatile indoles (skatole indole), which may be responsible for sensory defects. The risk off-flavours is even higher when graze alfalfa, because it particularly rich rapidly degradable proteins. Here, we investigated whether a short concentrate stall-finishing period that previously grazed alfalfa influences quality traits. We compared three feeding treatments, using groups 10 male Romane lambs:...

Abstract Intake, digestibility, nitrogen (N) balance, microbial protein synthesis, weight gain, yields of the main commercial cuts and carcass morphometric measurements were evaluated in lambs fed diets containing different levels chitosan. Sixty Santa Inês crossbred sheep with an average body (BW) 24 ± 2.2 kg assigned to three treatments (diets 0, 136 or 272 mg chitosan/kg BW) a completely randomized design. There was no effect chitosan on dry matter (DM) intake. Ingested retained N showed...
