Effect Of Thermo-Insulated Kid Hutch On Location Preference, Growth Performance, And Blood Haemato-Biochemical Indices Of Winter-Born Goat Kids (Capra Hircus), Ajoy Das, Dilip Kumar Mandal, Asish Debbarma, Muthupalani Karunakaran, Anupam Chatterjee, Debajyoti Sarkar

Turkish Journal of Veterinary & Animal Sciences

This study assessed the effect of thermo-insulated kid hutch (TIKH) on location preference, body surface temperature, growth performance, and blood haemato-biochemical indices of winter-born Black Bengal goat kids. Does were maintained in the same shed, born kids (n = 12) were divided into two groups along with mothers to begin experiments from day 1 of birth. The treatment group (TIKH) of kids was given a TIKH to which kids had free access, but not the adults. However, in the control group (CONT) kids were reared without TIKH. The floor surface temperature of TIKH was significantly (p < 0.05) higher at night as compared to goat shed in December (4.28%), January (3.98%), and February (7.72%). The interior roof surface of TIKH had 25.12%, 33.55%, 31.85%, 10.99%, and 4.37% higher (p < 0.01) temperatures at night compared to the roof surface temperature of the goat shed in December, January, February, March, and April, respectively. The presence of kids inside the TIKH at the age of 1–15 days was the greatest in morning (80.5%) and evening (72.2%). Between the ages of 16–-60 days, the preference of kids for the TIKH varied from 69.2% to 54.2% in the morning and from 70.0% to 66.7% in the evening. However, at the age of 61–75 days, kids’ preference for TIKH gradually declined in the morning (11.6%) and evening (19.9%) due to the increased inside temperature. Kids weaning weight was 23.25% higher (p < 0.05) in the TIKH group as compared to that of CONT. The average daily gain (0–30 days) was higher (41.34%; p < 0.05) in kids in the TIKH compared to the CONT shed. The haemato-biochemical profiles of kids were similar in both groups except for blood serum glucose, which was greater (p < 0.05) in kids of the TIKH than that of CONT shed. In conclusion, the provision of TIKH improved the growth and overall performance of winter-born Black Bengal goat kids during pre and postweaning periods.

Water Buffalo Social Networks During Their Activities On Pasture Under The Rain, Eleni Tsiobani, Maria Yiakoulaki, Nikolaos Hasanagas, Ioannis Antoniou Dec 2023

Water Buffalo Social Networks During Their Activities On Pasture Under The Rain, Eleni Tsiobani, Maria Yiakoulaki, Nikolaos Hasanagas, Ioannis Antoniou

Turkish Journal of Veterinary & Animal Sciences

Water buffaloes exhibit various social structures during their activities on pasture, but the impact of abiotic factors (i.e. rainfall) on these structures remains unknown. While existing research has provided evidence concerning the effect of weather conditions on grazing animals’ behavior, they have not examined how animals differentiate their social organization within the herd during their activities on pasture under the rainfall. This study utilized social network analysis to construct, depict, and analyze the proximity networks among buffaloes in each activity they perform on pasture before, during, and after the rainfall. By applying various network indices, we have shown that water …

The zoonotic origin of the COVID-19 pandemic virus highlights the need to fill the vast gaps in our knowledge of SARS-CoV-2 ecology and evolution in non-human hosts. Here, we detected that SARS-CoV-2 was introduced from humans into white-tailed deer more than 30 times in Ohio, USA during November 2021-March 2022. Subsequently, deer-to-deer transmission persisted for 2–8 months, disseminating across hundreds of kilometers. Newly developed Bayesian phylogenetic methods quantified how SARS-CoV-2 evolution is not only three-times faster in white-tailed deer compared to the rate observed in humans but also driven by different mutational biases and selection pressures. The long-term effect of …

Highly pathogenic avian influenza A(H5N1) viruses of clade 2.3.4.4b underwent an explosive geographic expansion in 2021 among wild birds and domestic poultry across Asia, Europe, and Africa. By the end of 2021, 2.3.4.4b viruses were detected in North America, signifying further intercontinental spread. Here we show that the western movement of clade 2.3.4.4b was quickly followed by reassortment with viruses circulating in wild birds in North America, resulting in the acquisition of different combinations of ribonucleoprotein genes. These reassortant A(H5N1) viruses are genotypically and phenotypically diverse, with many causing severe disease with dramatic neurologic involvement in mammals. The proclivity of …

The Developmental Process For Adenoviral Vectored Canine Influenza Vaccines, Nicholas Jeanjaquet Dec 2023

The Developmental Process For Adenoviral Vectored Canine Influenza Vaccines, Nicholas Jeanjaquet

School of Biological Sciences: Dissertations, Theses, and Student Research

Canine Influenza Virus (CIV) is a recently emerged branch of Influenza A virus that is highly infectious in dogs. The first strain was isolated in 2003, and it has quickly become endemic in areas with dense dog populations, most notably in Asia. The proximity of dogs to humans, along with their potential to serve as mixing vessels for reassortment, raises concern for possible zoonotic transmission and a potential human pandemic. Available vaccines are not frequently updated and struggle to prevent the spread of currently circulating strains. This highlights the need for a new and more effective vaccine. We outline the …

Comparison Of Carcass Characteristics, Meat Quality, And Fatty Acid Composition In Slowand Fast-Growing Broilers At Different Slaughter Weights, Büşra Yaranoğlu, Hi̇lal Çapar Akyüz, Esi̇n Ebru Onbaşilar

Turkish Journal of Veterinary & Animal Sciences

This study aimed to compare the slaughter, meat quality characteristics, and fatty acid composition of fast-growing (FAG) and slow-growing (SWG) broilers at different slaughter weights. In the experiments, a total of 90 carcasses were used: 45 SWG (Hubbard-Isa Red JA) and 45 FAG broilers (Ross 308) with 15 carcasses from each slaughter weight group (1500 ± 50 g, 2000 ± 50 g, 2500 ± 50 g). Hot carcass yield and cold carcass yield detected in the FAG broilers were higher than in SGW broilers (p < 0.001). As the weight of slaughter increased, hot carcass and cold carcass yield increased (p < 0.001). The breast percentage was significantly lower in the SWG broilers compared to the FAG broilers (p < 0.001). In contrast, thigh, wing, and abdominal fat percentages were higher in the SWG broilers (p < 0.001). The breast percentage increased as the slaughter weight increased (p < 0.001). SWG broilers had significantly lower pH, except for the pH 24 of the thigh meat (p < 0.01). The L*, a*, and b* values of the SWG broilers were lower than the FAG broilers (p < 0.01). In terms of a* values determined initially and at the 24th h in the breast and thigh meat, the 1500 g slaughter weight group had by far the highest value (p < 0.01). SWG broilers had significantly lower values in terms of cooking loss, water-holding capacity, and drip loss (p < 0.001). C18:2ω6 was detected at higher amounts in the FAG broilers (p < 0.05). The FAG broilers had higher PUFA, desired fatty acids, PUFA/SFA, and thrombogenic index values (p < 0.05). The results show that FAG broilers can meet the strong worldwide demand for meat quantity and quality. Slaughter weight changes only affected the quantity of the meat.

This study aimed to evaluate quantitative and morphometric analyses of preantral follicles and the ultrastructural characteristics of antral follicles in different oestrous cycle stages in Anatolian water buffaloes. Twenty-four ovaries collected from twelve slaughtered Anatolian water buffaloes were classified macroscopically as luteal or follicular stages. The ovaries were prepared for histological examination (Hematoxylin-eosin staining), and primordial, primary, and secondary follicle numbers were calculated, and the diameters of oocytes, follicles, and nuclei were measured under a light microscope with a micrometre. The theca and granulosa cells of antral follicles were observed under a transmission electron microscope. The mean number of preantral …

Highly pathogenic avian influenza viruses (HPAIVs) of the A/goose/Guangdong/1/1996 lineage H5 clade 2.3.4.4b continue to have a devastating effect on domestic and wild birds. Full genome sequence analyses using 1369 H5N1 HPAIVs detected in the United States (U.S.) in wild birds, commercial poultry, and backyard flocks from December 2021 to April 2022, showed three phylogenetically distinct H5N1 virus introductions in the U.S. by wild birds. Unreassorted Eurasian genotypes A1 and A2 entered the Northeast Atlantic states, whereas a genetically distinct A3 genotype was detected in Alaska. The A1 genotype spread westward via wild bird migration and reassorted with North American …
