Environmental And Genetic Effects On Birth Weight And Survival Rate In Holstein Calves, Serdar Koçak, Mustafa Tekerli̇, Ceyhan Özbeyaz, Banu Yüceer

Turkish Journal of Veterinary & Animal Sciences

This study was undertaken to investigate the effects of certain factors on birth weight and survival rate, utilizing the records of 8399 Holstein calves maintained at the Ceylanpınar State Farm in southeastern Anatolia. The data were collected from the calf barn sheets, including birth weight, pedigree details, and calf fate. The survival rate was scored as 1 (alive) or 0 (died) in accordance with the records. Analysis of variance indicated that the effects of year, season, parity, and calf sex on birth weight were significant (P < 0.01). Only calf sex had a significant (P < 0.01) influence on survival rate. The least squares means of birth weight for all calves averaged 38.79 ± 0.171 kg. The survival rates were 0.95 ± 0.004, 0.94 ± 0.004, and 0.92 ± 0.005 at 3, 6, and 12 months of life, respectively. Heritabilities were 0.115 ± 0.0023 for birth weight and 0.020 ± 0.009, 0.011 ± 0.008, and 0.011 ± 0.008 for 3-month, 6-month, and 12-month survival rates. Genetic correlations between birth weight and every rate of survival were estimated as -0.113, -0.012, and 0.106. The corresponding phenotypic correlations were 0.022, 0.014, and -0.013. It was concluded that the birth weight and survival rates of Holstein calves reared at Ceylanpınar State Farm were acceptable. However, further improvements can be accomplished by more effective feeding and management based on the low heritabilities.

The Pet Food Recall Puzzle: Who, What, Why, And How Much, Roxanne Greitz Miller

Education Faculty Articles and Research

Last spring, North America was gripped in the largest pet food recall in history. News outlets reported tens of thousands of dogs and cats becoming ill, and many dying, as a result of ingesting contaminated pet food. Several pet owners have filed lawsuits against the manufacturers and distributors of the pet food products. I think this is an excellent real-life science story to use with students to show science investigation in action, and to discuss the intersections between the role of regulatory agencies and the public.

In order to understand the case, you first have to know the facts. We'll …

Haemato-Biochemical Aspects Of Parturient Haemoglobinuria In Buffalo, Muhammad Zubair Akhtar, Ahrar Khan, Muhammad Zargham Khan, Ghulam Muhammad

Turkish Journal of Veterinary & Animal Sciences

This study aimed to determine the haematological and biochemical changes that occur in buffaloes with parturient haemoglobinuria (PHU). For this purpose, serum samples from 60 PHU-affected and 60 apparently healthy buffaloes were collected and analysed. Mean erythrocyte count (3.6 ± 1.0 10^{12}/l), haemoglobin concentration (5.8 ± 1.4 g/dl), and haematocrit (16.9 ± 2.8 %) of the PHU-affected buffaloes were lower (P < 0.001), while their erythrocyte sedimentation rate (104.1 ± 36.2 mm/h) was higher (P < 0.001) in comparison to the healthy buffaloes. Neutrophils (43.0 ± 4.5%), urea (49.7 ± 7.8 mg/dl) and creatinine (2.1 ± 0.4 mg/dl) concentrations were significantly higher in the PHU-affected buffaloes, while lymphocytes (48.7 ± 2.9%) and erythrocytic glucose-6-phosphate dehydrogenase (G6PD) (92.3 ± 13.2 mU/10^9 TECs) were lower than in the healthy buffaloes. Serum phosphorus (1.9 ± 0.6 mg/dl) and copper (65.4 ± 6.0 \mu g/dl) were lower (P < 0.001), while molybdenum (171.5 ± 56.7 \mu g/dl) was higher in the PHU-affected buffaloes as compared to those values in the healthy buffaloes. It was concluded that PHU-affected buffaloes usually suffer from severe anaemia and hypophosphataemia, and erythrocytes with significantly reduced G6PD are prone to haemolysis, leading to haemoglobinuria in buffaloes.

Research Strategies To Reduce Bovine Tuberculosis Transmission From Wildlife To Cattle, Are R. Brentensen, Mike R. Dunbar, Robert G. Mclean

Michigan Bovine Tuberculosis Bibliography and Database

Bovine tuberculosis (bTB) is a zoonotic disease caused by Mycobaterium bovis, and is transmissible to humans, wildlife and domestic livestock. In the northern Lower Peninsula of Michigan, white-tailed deer ( Odocoileus virginianus) serve as a reservoir for the disease and pose a significant threat to domestic cattle and captive cervids. Scientists at USDA, APHIS, Wildlife Services, National Wildlife Research Center have designed a variety of laboratory and field studies aimed at reducing or eliminating bTB infection in cattle by interrupting the transmission of the disease from wildlife reservoirs. These strategies include reducing bTB in deer by delivery of …

Research Strategies Of The National Wildlife Research Center To Control Bovine Tuberculosis In Wildlife In Michigan, Usa, A. R. Berentsen, M. R. Dunbary, R. G. Mclean

Michigan Bovine Tuberculosis Bibliography and Database

Bovine tuberculosis (bTB) is a zoonotic disease caused by Mycobaterium bovis and is transmissible to humans, wildlife, and domestic livestock. In the United Kingdom, the suspected wildlife reservoir of bTB is the badger (Meles meles) (HUTCHINGS and HARRIS, 1997), and in New Zealand, the culprit is the brush-tailed possum (Trichosurus vulpecula) (MORRIS et al., 1994). In northern Michigan, USA, bovine tuberculosis is endemic in white-tailed deer (Odocoileus virginianus). In 1975 a hunter-killed white-tailed deer in Alpena County, Michigan, USA, was tested positive for bTB. Subsequent surveillance by the Michigan Department of Natural Resources (MDNR) …

Michigan Bovine Tuberculosis Bibliography and Database

In recent decades the management of large game mammals has become increasingly intensive in south central Spain (SCS), resulting in complex epidemiological scenarios for disease maintenance, and has probably impeded schemes to eradicate tuberculosis (TB) in domestic livestock. We conducted an analysis of risk factors which investigated associations between the pattern of tuberculosis-like lesions (TBL) in wild boar (Sus scrofa) and red deer (Cervus elaphus) across 19 hunting estates from SCS and an extensive set of variables related to game management, land use and habitat structure. The aggregation of wild boar at artificial watering sites was …

Vaccination Of White-Tailed Deer (Odocoileus Virginianus) With Mycobacterium Bovis Bacillus Calmette Guerin, M. V. Palmer, T. C. Thacker, W. R. Waters

Michigan Bovine Tuberculosis Bibliography and Database

Wildlife reservoirs of Mycobacterium bovis represent serious obstacles to the eradication of tuberculosis in domestic livestock. In Michigan, USA tuberculous white-tailed deer transmit M. bovis to cattle. One approach in dealing with this wildlife reservoir is to vaccinate deer in order to interrupt the cycle of deer to deer and deer to cattle transmission. Thirty-one white-tailed deer were assigned to one of three groups; 2 SC doses of 10⁷ CFU of M. bovis BCG (n = 11); 1 SC dose of 10⁷ CFU of M. bovis BCG (n = 10); or unvaccinated deer (n = 10). …

Evaluating The Effect Of Two Commercial Antimicrobial Products On Salmonella Spp. In The Aquatic Habitat Of The Red-Eared Slider Turtle (Trachemys Scripta Elegans), Trevor Theadore Zachariah

LSU Master's Theses

Turtle-associated salmonellosis was recognized as a public health concern in the 1960’s, particularly due to an increase in the incidence of disease among children. In response to the public health threat, the United States Food and Drug Administration (FDA) implemented regulations in 1975 restricting the sale of turtle eggs and turtles with a carapace length less than 10.2 cm. Since that time, attempts to eliminate Salmonella from turtles using antibiotics have been unsuccessful and lead to antibiotic resistant strains of Salmonella on turtle farms. Recent work has focused on identifying non-antibiotic products to suppress or eliminate Salmonella and reverse the …

Depletion Of 32-Kbp Circular Plasmids From Borrelia Burgdorferi, Amanda Paige Derouen Polito

LSU Master's Theses

The Lyme disease spirochete Borrelia burgdorferi has a very unusual genome composed of one linear chromosome and up to 21 linear and circular plasmids. Several plasmids are known to be important either for mammalian infection or tick colonization. A single spirochete harbors up to 7 different cp32 plasmids; however, nothing is known about their role in mammalian infection. The plasmids in this family are well maintained during in vitro cultivation, making it difficult to study their functions. To effectively deplete the plasmids, an 8kbp fragment containing essential elements for replication and partitioning in B. burgdorferi was amplified from one of …

The Role Of Toll-Like Receptor 7 In The Neuropathogenesis Of Retrovirus Infection In Neonates, Stephanie Diane Lewis

LSU Master's Theses

Viral infections of the central nervous system (CNS) in infants are rare; however, they are associated with high morbidity and mortality rates. These virus infections often induce strong innate immune responses in the brain including: the production of cytokines and chemokines, the activation of astrocytes and microglia and the recruitment of macrophages. Innate immune responses are often initiated by toll-like receptors (TLR). Several studies have demonstrated that toll-like receptor 7 (TLR7) can be stimulated by single-stranded RNA from multiple viruses. In the current study, we examined the mechanism by which TLR7 contributes to neuroinflammation in the neonatal brain using a …

Effect Of Feeding Supplemental Tallow On The Performance Of Lactating Nili-Ravi Buffaloes, Haq Nawaz, Muhammad Yaqoob, Muhammad Abdullah

Turkish Journal of Veterinary & Animal Sciences

In order to determine the feeding value of tallow for lactating Nili-Ravi buffaloes, 4 buffaloes were fed 0%, 2%, 4%, or 6% tallow in a 4 X 4 Latin square experiment. The intakes of dry matter (DM), organic matter (OM), crude protein (CP), acid detergent fiber (ADF), and neutral detergent fiber (NDF) decreased (P < 0.01), but the intakes of ether extract (EE) (P < 0.01) and digestible energy (DE) (P < 0.05) increased with increasing levels of tallow in the diets. Intake of net energy for lactation (NE_L) did not differ (P < 0.01) with varying levels of supplemental tallow. Daily milk yield increased (P < 0.01) from 11.00 to 13.2 kg/day. Production of 4% fat corrected milk (FCM), solid corrected milk (SCM), and energy corrected milk (ECM) increased quadratically (P < 0.05) with the increasing level of tallow in the diets. Milk fat content and total milk fat increased linearly (P < 0.01) and quadratically (P < 0.05), respectively, as the level of tallow in the diet increased. There was no difference in protein and lactose content due to feeding tallow. Total solid content increased quadratically (P < 0.05) from 16.45% to 17.67% but solid not fat (SNF) percentages did not vary with varying levels of tallow. The gross energy (GE) of the milk increased from 1096 to 1160 Kcal/kg (P < 0.01) with increasing levels of tallow in the diets. Energetic efficiency of milk production improved in a quadratic (P < 0.05) manner with 2%, 4%, and 6% tallow, with the highest being 47.6% with 4% supplemental tallow. The proportion of C_{8:0} to C_{16:1} fatty acids (FA) decreased from 53.66% to 35.52%, whereas the concentration of C_{18:0} to C_{20:0} increased (44.93% to 62.84%) in the milk fat of buffaloes fed diets containing different levels of tallow. Gains in body weight (BW) were higher (P < 0.05) in buffaloes fed diets containing supplemental tallow as compared to those fed the control diet. This study suggests that tallow up to 6% of diet DM is a suitable fat supplement as an economical energy source for lactating buffaloes.
