“…Enquanto Campos et al (2010) observaram que na ausência de enriquecimento ambiental, os leitões brincam menos, fuçam mais e apresentam aumento de comportamento estereotipado. Quando se enriquece o ambiente se quebra a monotonia estimulando o leitão a apresentar outros comportamentos como brincar e explorar o ambiente em detrimento das atividades de brigar, vício de sucção e manipulação da cauda (BEZERRA et al, 2019).…”

O ambiente em que o animal habita está relacionado com o comportamento que esse vai expressar, portanto, problemas comportamentais podem ser indicativos de deficiências ambientais ou de manejo, alterando o bem-estar do animal. O objetivo deste trabalho foi avaliar o comportamento de leitões, na fase de creche, de acordo com variações de temperatura e umidade do ambiente em granja comercial localizada em Maranguape-Ceará. Foram utilizados 60 leitões de ambos os sexos desmamados aos 21 dias de idade com peso médio de 6,1±0,4 kg distribuídos em quatro baias de 15 animais cada, que foram observados em dois horários por dia. Foi instalada uma câmera, na parte superior da baia, para fazer a filmagem dos leitões, que filmava das 05:00 horas às 07:00 horas da manhã, e de 12:00 horas às 14:00 horas da tarde, além de serem registradas a temperatura e umidade, através de um termohigrômetro. Para analisar o comportamento dos animais foi utilizada uma ficha de etograma, calculando-se os percentuais de ocorrência de cada comportamento. As médias de temperatura registradas foram 25 e 28 °C e de umidade 84% e 73% para os horários 05:00 horas e 12:00 horas, respectivamente. Os animais passaram a maior parte do tempo dormindo ou deitados (69 e 70%) em ambos os horários de observação. O comportamento apresentado pelo animal pode ser um indicativo de conforto térmico, situação essencial para expressão de seu potencial produtivo. Palavras-chave: Bem-Estar Animal. Conforto Térmico.

Abstract The environment in which the animal lives is related to the behavior it will express, so behavioral problems may be indicative of environmental or management deficiencies, altering the animal’s welfare. The objective of this work is to evaluate the piglets behavior in the nursery phase according to temperature and humidity variations in a commercial farm located in Maranguape-Ceará. Sixty piglets of both sexes weaned at 21 days of age with an average weight of 6.1±0.4 kg were used, distributed in four pens of 15 animals each, which were observed at two times per day. A camera was installed in the upper part of the pen for filming the piglets, which filmed from 5:00 am to 7:00 am, and from 12:00 pm to 2:00 pm, and was recorded at temperature and humidity through a hygrometer term. To analyze the animals behavior, an ethogram form was used. The average temperatures recorded were 25 and 28 °C and humidity 84% and 73% at 05:00 a.m. and 12:00 p.m. hours, respectively. The animals spent most of the time sleeping or lying down (69 and 70%) at both observation times. The behavior shown by the animal can be an indication of thermal comfort, an essential situation for the expression of its productive potential. Keywords: Animal Welfare. Thermal Comfort. Ethogram.

Homeopathic Products as a Complementary Dietary Additive for Pigs in their Growing and Finishing Phases

et al. 2022

Background Homeopathic products (HP) have been proposed for the prevention of disease and as a complementary dietary additive in pig farming, with resulting improved performance and quality of life of the animals and with benefits for food safety. The aim of this study was to assess the addition of HP to pig feed and its effects on growth performance, dietary protein utilization, nutrient digestibility, meat quality, and economic feasibility. Methods A total of 80 male pigs, body weight 32.8±2.3kg, were allocated in a randomized design, with two treatments of 10 replications and four animals per experimental unit. Treatments were composed of a control diet (CD) or CD+HP (Finalvitaplus+Figotonus, 1.1kg/ton feed of each product). The outcome measures used were growth performance (body weight gain) and feed efficiency (body weight gain per unit of feed consumed), efficiency of dietary protein utilization (blood urea nitrogen), nutrient digestibility (apparent digestibility coefficient and apparent nutrient digestibility), meat quality (including pH, temperature, color, liquid loss by cooking and thawing, intramuscular fat and meat tenderness), and economic feasibility (cost of the diets). Results There was no effect (p >0.05) of treatments on growth performance of the pigs, though the group that received HP showed an 8.93% greater feed efficiency than the control group (p=0.077). The animals in the control group had a 14.37% higher blood urea nitrogen concentration in the finishing I phase (70–100kg body weight) compared with those fed HP (p=0.028), indicating lower protein utilization in the controls. There was comparative improvement in digestibility coefficient and in nutrient digestibility in pigs fed HP in the growing–finishing phase (p <0.05). There was no differential effect of treatments on meat quality or economic feasibility (p >0.05). Conclusion The addition of HP to the diet of growing–finishing pigs produced some improvement in their dietary protein utilization, nutrient digestibility and feed efficiency, though it did not affect their growth performance, meat quality or economic feasibility.

“…The ratio between neutrophils and lymphocytes was measured from each differential WBC in order to obtain N:L ratio. Quantification of serum malondialdehyde (MdA) was performed according to (BEZERRA et al, 2019) and expressed in serum as nmol/mL (dRAPER & HAdLEY, 1990).…”

Considering the benefits that massage can promote, this research aimed to apply the stroking massage in five adult goats (G1-G5) assessed in group and individually for ten days. Parameters related to massage, immune system, physiology and behavior of goats were observed. There was only significant difference (P<0.05) regarding behavior expressed in the presence of the masseur in G4 and G5, between week 1 and 2. Most goats accepted massage, except G2, with greater demonstrations of positive than negative behavior towards the masseur. Therefore, stroking massage promoted positive interactions between the masseur and goats, and should be explored as an alternative method to those existing in improving the relationship between humans and farm animals.
