“…of the pullets are associated with such experiments. Some effects of handling, with and without blood sampling, on growth have been reported by McPherson et al (1961), Reichmann et al (1978), and Gross and Siegel (1979). In preliminary studies, Zaalmink (1979) measured metabolic rate in pullets 3 to 5 days after immunization; however, the immediate response of injection or immunization on metabolic rate was not measured.…”

The effect of intramuscular (IM) injection, per se, on heat (H) production was investigated in ad libitum- and restricted-fed pullets held at normal (21 C) and low (10 C) environmental temperatures. At 21 C IM injection, per se, decreased H-production of ad libitum- and restricted-fed pullets for 2 to 4 hr after injection. This effect was significant (P less than .01) in ad libitum-fed pullets, held at 21 C as well as at 10 C. Thus, when studying the effect of an immune response on the energy metabolism, an effect may be confounded with the effect of the IM injection per se when the measurements are made during the first 2 to 4 hr following injection.

“…The enhanced disease resistance and immune response in those studies could be associated with the stress modulating effect of human contact. However, others demonstrated that positive tactile interaction either had negligible [47] or negative effect [48] on growth performance. Nature of the physical contact, breed and age differences may have accounted for the discrepancies.…”

Humans and animals are in regular and at times close contact in modern intensive farming systems. The quality of human-animal interactions can have a profound impact on the productivity and welfare of farm animals. Interactions by humans may be neutral, positive or negative in nature. Regular pleasant contact with humans may result in desirable alterations in the physiology, behaviour, health and productivity of farm animals. On the contrary, animals that were subjected to aversive human contact were highly fearful of humans and their growth and reproductive performance could be compromised. Farm animals are particularly sensitive to human stimulation that occurs early in life, while many systems of the animals are still developing. This may have long-lasting impact and could possibly modify their genetic potential. The question as to how human contact can have a positive impact on responses to stressors, and productivity is not well understood. Recent work in our laboratory suggested that pleasant human contact may alter ability to tolerate various stressors through enhanced heat shock protein (hsp) 70 expression. The induction of hsp is often associated with increased tolerance to environmental stressors and disease resistance in animals. The attitude and consequent behaviour of stockpeople affect the animals’ fear of human which eventually influence animals’ productivity and welfare. Other than attitude and behaviour, technical skills, knowledge, job motivation, commitment and job satisfaction are prerequisites for high job performance.

“…A total of 370 serum samples were collected via venipuncture of the wing vein from the farms under study ( Supplementary Table). Sera were separated as previously described [30]. The collected sera were heat inactivated at 56°C for 30 min then stored at -20°C.…”

Molecular characterization and phylogenetic analyses of virulent infectious bronchitis viruses isolated from chickens in Eastern Saudi Arabia

et al. 2017

Infectious bronchitis virus (IBV) is one of the major respiratory viral threats for chickens. Despite the intensive application of IBV vaccines, several outbreaks have been reported worldwide. Here, we report several IBV outbreaks in thirteen poultry farms in Eastern Saudi Arabia (ESA) from 2013 to 2014. The main goals of the current study were as follows: (1) isolation and molecular characterization of the currently circulating strains in ESA (Al-Hasa, Dammam, and Buqayq) and (2) evaluation of the immune status of these birds to IBV. To achieve our goals, tissue specimens (trachea, lungs, liver, kidney and cecal tonsils) and sera were collected. High morbidity up to 100% and mortality ranging from 18 to 90% were reported. Severe infection was observed in the trachea, bronchi, and kidneys of the infected birds. IBV strains were isolated using embryonated chicken eggs. The isolated viruses induced hemorrhage, dwarfing and death of the inoculated embryos 3-5 days post-infection. The circulating IBV strains were identified by sequencing the partial IBV-N and IBV-S1 genes. These viruses showed 95% sequence identity to Indian, Italian, Egyptian and Chinese strains and were quite distinct from the locally used vaccines on the genomic level. Interestingly, high antibody titers against IBV were reported in some of these farms, suggesting the presence of new virulent strains in ESA. The seroconversion of infected birds was reported among the affected flocks. In conclusion, very virulent IBV strains are currently circulating in ESA. Further studies are currently in progress to molecularly characterize these IBV strains.

Effects of regular handling and blood sampling by wing vein puncture on the performance of broilers and pullets

Abstract: 1. Broilers and pullets were regularly handled or bled by wing vein puncture over periods of 5 and 31 weeks respectively. 2. Neither procedure had any effect on body weight, food consumption nor on egg production, egg weight, shell quality or the percentage of non-marketable eggs.
