Performance, carcass characteristics and litter moisture in broilers housed at two densities Animal Sciences
Gopinger, Edenilse; Avila, Valdir Silveira de; Perondi, Dani; Catalan, Aiane Aparecida da Silva; Krabbe, Everton Luis; Roll, Victor Fernando Büttow.
The effect of stocking density in broiler chickens (11.08 and 13.20 birds m-2), between 5 and 45 days of age, was assessed with regard to performance, cut yield, litter moisture and frequency of pododermatitis injuries. Further, 476 one-day chicks Cobb 500® were distributed in a completely randomized design at two densities (birds m-²), with seven replications per treatment in 14 experimental units. Birds housed at a lower density (11.08) increased feed intake (p < 0.05), without any effect on weight gain and feed conversion. Retail yields were not influenced (p > 0.05) by treatments. In the case of higher density (3.20)the litter showed higher moisture content (p < 0.05) at 28 and 35 days of age. There was a higher occurrence of pododermatitis in...

Defining upper critical temperatures for an effective climate control to reduce heat stress CIGR Journal
Sanz, Salvador Calvet.
The definition of homeotherm animal responses to temperature has traditionally based on metabolic and thermal physiology studies. The thermoneutral zone is defined as the range of ambient temperature within which metabolic rate is at a minimum, and within which temperature regulation is achieved by non-evaporative physical processes alone. As temperature raises, animals the upper critical temperature is reached, which is the ambient temperature above which thermoregulatory evaporative heat loss processes of a resting thermoregulating animal are recruited. These temperatures depend on a variety of factors including animal species and breed, age, adaptation or animal status, among others. These are influenced by other environmental conditions such as...

Efficiency of eugenol as anesthetic for the early life stages of Nile tilapia (Oreochromis niloticus) Anais da ABC (AABC)
Ribeiro,Paula A.P.; Miranda-Filho,Kleber C.; Melo,Daniela C. de; Luz,Ronald K..
In aquaculture, activities with anesthetic compounds are usually used in order to ensure the welfare of farmed fish, allowing handling out of water with decreased trauma by stress. Presently, there is no information about anesthetic action of eugenol in early life stages of Nile tilapia (Oreochromis niloticus). The objective of this study was to evaluate different concentrations of eugenol for larvae and juveniles of Nile tilapia. Sixty animals were used for each group of weight, group I = 0.02 g; group II = 0.08 g; group III = 0.22 g; group IV = 2.62 g; and group V = 11.64 g. The eugenol concentrations tested were 50, 75, 100, 125, 150 and 175 mg L-1. No mortality was reported during the tests with eugenol. Tilapia larvae with 0.02 g and juveniles around...

Rearing system and behavioural adaptation of laying hens to furnished cages Ciência Rural
Roll,Victor Fernando Büttow; Levrino,Gustavo Adolfo Maria; Briz,Ricardo Cepero.
The influences of floor and cage-rearing on behavioural adaptation to furnished cages were investigated in laying hens. Two groups of 180 Isa Brown commercial layer pullets were reared in cages (CR) or floor pens (FR) and transferred to furnished cages, where their behavioural adaptation was observed throughout the laying period (18-78 wks of age). At 17 weeks of age, hens were placed in one of the 36 furnished cages with 10 birds in each cage, each containing a nest box, perches, a dust bath, and abrasive strips. At 50 and 54 weeks of age, direct visual observation and video recording were used to assess hen’s behaviour. From 21 weeks of age, the dust-bath activities of leg-banded hens in eight cages per treatment were recorded. The amount of time spent...

Comparison of salivary cortisol concentrations in Jaguars kept in captivity with differences in exposure to the public Ciência Rural
Montanha,Julio César; Silva,Sérgio Leme; Boere,Vanner.
For the most part, jaguars kept in captivity are used for educational and recreational purposes and it hasn't been determined the different impacts that public exposure would have on these animals. In this study, we compared the salivary cortisol, one of the stress indicator hormones, in seven captive jaguars exposed to the high and low public visitation. Saliva was collected using an absorbent material that was chewed by the animals and subsequently analyzed through an immunoenzymatic assay. Salivary cortisol concentrations were significantly higher in the jaguars with higher public exposure, which suggest a more hormonal stress response. These results indicated that jaguars, animals usually of solitary and secretive behavior, may have their welfare...

Vieira,Frederico Márcio Corrêa; Silva,Iran José Oliveira da; Barbosa Filho,José Antonio Delfino; Vieira,Afrânio Márcio Corrêa; Rodrigues-Sarnighausen,Valéria Cristina; Garcia,Danilo de Brito.
Concerning the reduction of preslaughter death losses, high temperature and relative humidity in the tropics are the major concerns regarding broiler survival prior slaughtering. However, the relationship between different lairage times under controlled environment and the thermal condition outside the holding area is still unclear. Thus, the aim of this study was to compare different intervals of lairage time with different environmental temperature and relationship with poultry mortality rates. A study was conducted in a commercial poultry abattoir in the State of Sao Paulo, Brazil, in the year of 2006. The historical data set from 13,937 trucks, about broiler mortality during preslaughter operations, was given by the abattoir. Factors that influence the...

Las microfinanzas en las condiciones de vida, ingreso y cultura financiera y empresarial. El caso de FINSOL Texcoco-Chimalhuacán, Estado de México Colegio de Postgraduados
Sampayo Paredes, Humberto.
En México, como en prácticamente todo el mundo, se experimenta un acelerado crecimiento del sector de las microfinanzas de corte comercial, aun cuando se trata de un sector relativamente nuevo; desde principios de la década los 90´s, para el caso específico de México. Ello se debe a cuatro factores básicos: a) La enorme demanda de servicios financieros por parte de millones de personas de bajos ingresos; b) El diseño de una tecnología apropiada para acercar estos servicios a esa población; c) La presencia de inversionistas dispuestos a invertir en esta industria y; d) La difusión mundial que se le ha dado como instrumento de combate a la pobreza (objetivos del milenio). Lo anterior ha dado origen a múltiples estudios enfocados a evaluar los...

Impacts of the 2010 Droughts and Floods on Community Welfare in Rural Thailand: Differential Effects of Village Educational Attainment Ecology and Society
Climatic events can have disastrous consequences on rural livelihoods, which rely mainly on agriculture and natural resources. The way households and communities respond to climatic shocks depends on their available resources. We formulated that education is a human capital asset that can increase coping abilities in difficult times because education improves access to both social and economic resources. Based on the Thai government surveys of the living conditions and life quality of 68,343 rural villages for the years 2009 and 2011, we investigated the impacts of floods and droughts in 2010 on community welfare, i.e., consumption and income in 2011 at the village level. Using difference-in-difference methods, we analyzed how differential demographic...
