ABSTRACT: The increasing of global demand for food has required more efficiency in the production process. Transportation represents a source of body dehydration for pigs transported from farm to slaughterhouses. This study aimed to evaluate the effects of the distances on the body dehydration of pigs transported to slaughter in tropical conditions. We analyzed 350 pigs shipments with a total of 68,588 heads using statistical software SAS by anova, means and corr procedures. The results showed a liveweight loss estimated at 12% which was increased gradually as the distance increased as pigs were deprived of water for a long time. The most cost-effective distance for the pigs' transportation under tropical condition is within the range below 100 km, where...

SOWS AND PIGLETS THERMAL COMFORT: A COMPARATIVE STUDY OF THE TILES USED IN THE FARROWING HOUSING
Provedor de dados: Engenharia Agrícola
Autores: Machado,Sivanilza T.; Nääs,Irenilza De A.; Reis,João G. M. Dos; Caldara,Fabiana R.; Santos,Rodrigo C.
ABSTRACT The global animal production is increasing as expected to meet world demand for food, especially for meat products. This research aimed to investigate the effect of two types of roofs (clay and fiber-cement tiles) in a tropical area on the thermal comfort of farrowing sows and piglets. Twelve sows and forty-eight piglets were observed during summer in the Southeast region of Brazil. Climate variables, thermal comfort and surface temperature (sows and piglets) were assessed. The type of roofs clearly affected the piglets' surface temperature during all studied periods, but the results were not similar in the sows' surface temperature. Temperature and humidity index found was high in the building with fiber-cement tiles. The pen location in the...

Ammonia emissions from a naturally and a mechanically ventilated broiler house in Brazil
Provedor de dados: Revista Brasileira de Engenharia Agrícola e Ambiental
Autores: Mendes,Luciano B.; Tinoco,Ilda F. F.; Ogink,Nico W. M.; Rocha,Keller S. O.; Osorio S.,Jairo A.; Santos,Marilú S.
This study was conducted with the aim of monitoring NH3 emissions from a mechanically and a naturally ventilated broiler house (MVB and NVB, respectively) and calculate their ammonia emission factors (fNH3). Bird stocking density was 13.5 and 11.1 birds m-2 for the MVB and NVB, respectively. The marketing age was 43 days and bedding consisted of dried coffee husks in its first time of use. Ventilation rates were calculated with the metabolic carbon dioxide mass balance method. Values of fNH3 were 0.32 ± 0.10 and 0.27 ± 0.07 g bird-1 d-1 for the MVB and NVB, respectively, and are in agreement to what was presented in other studies performed under similar conditions. The fNH3 estimated on yearly basis was 58 g bird-place-1 year-1. It was concluded that the...

LACTOPEROXIDASE SYSTEM UNDER TROPICAL CONDITIONS: USE, ADVANTAGES AND LIMITATIONS IN CONSERVATION OF RAW MILK AND POTENTIAL APPLICATIONS
Provedor de dados: Revista de Salud Animal
Autores: Ponce,P.
The existent knowledge about the use of the Lactoperoxidase system (LPs) on the preservation of raw milk confirms its innocuity to human health, which allowed the lifting of the restriction for system to be used for milk products for international dairy market. Under tropic conditions, thiocyanate concentration needed for activating LPs can be reduced to about half of the established in the Codex Alimentarius guidelines, increasing its use security. When the antimicrobial effect of the LPs disappeared, exacerbation of the pathogen microorganisms was not observed, neither an inhibitory effect on the lactofermentant bacteria, in every case in wich milk was previously pasteurized to 850C during 20 minutes. This method maintains the initial quality of raw...
