N’Dama Cattle

Records of 4184 N'Dama calves born between 1947 and 1984 at Fashola Stock Farm, Oyo State, Nigeria was used to compute inbreeding coefficient and determine its effects on calving intervals of cows. Only 273 of the 4184 calves (6.53%) were inbred with an average inbreeding coefficient of 9.71%, while five out of 293 sires had inbreeding coefficient of 9.25% and 43 out of 1849 dams had inbreeding coefficient of 9.95%. The inbreeding coefficient for the entire population was 0.63%, respectively 0.70% and 0.58% for male and female calves. The average calving interval was 445.34 ± 2.68 days within the herd while year of birth, parity of dam, age of dam and dam's age at first calving all significantly (P<0.05) impacted calving intervals of cows. Season of birth and inbreeding coefficient of dam did not exert statistical (P>0.05) influence on calving intervals of dams. Although the number of inbred animals in the population is relatively low, however the inbreeding level of these animals is high, which may be attributed to the fact that breeding policy on the farm was not strictly adhered to, and lack of proper and adequate registration system coupled with inconsistent animal identification system on the farm may be responsible for the inbreeding observed in the N'Dama population at Fashola Stock Farm.

Control And Management

The Federal scientific Agroengineering center VIM has developed technical tools, algorithms and software for the intelligent automatic control system for milking animals “Stimul” on the “Herringbone” milking unit in three versions. The created system does not include automatic selection gates for effective management of zootechnical and veterinary services of animals. (Research purpose) The research purpose is in developing an intelligent machine for automatic sorting of animals for servicing and managing the herd according to specified characteristics. (Materials and methods) The article presents the development of control and management systems in dairy farming based on the conceptual principles of digital transformation. The digital control system is based on a multifunctional panel controller. The created control unit has a port for connecting to the RS 485 network and provides support for network functions via the Modbus Protocol. The programming of the control unit has been made in the SMLogix tool environment, which supports the FBD function block language. (Results and discussion) The article presents an intelligent machine for automatic sorting of animal flows for servicing and managing the herd according to specified characteristics with the unification of hardware, software modules and interface. The article describes the necessary parameters for the automatic remote animal identification system, the basic component of the control system of an intelligent machine for sorting animals according to specified characteristics. (Conclusions) The machine allows to automatically identify, sort and send animals to the specified areas for individual service.

Barge, P., Gay, P., Merlino, V. and Tortia, C. 2013. Radio frequency identification technologies for livestock management and meat supply chain traceability. Can. J. Anim. Sci. 93: 23–33. Animal electronic identification could be exploited by farmers as an interesting opportunity to increase the efficiency of herd management and traceability. Although radio frequency identification (RFID) solutions for animal identification have already been envisaged, the integration of a RFID traceability system at farm level has to be carried out carefully, considering different aspects (farm type, number and species of animals, barn structure). The tag persistence on the animal after application, the tag-to-tag collisions in the case of many animals contemporarily present in the reading area of the same antenna and the barn layout play determinant roles in system reliability. The goal of this paper is to evaluate the RFID identification system performance and determine the best practice to apply these devices in livestock management. RFID systems were tested both in laboratory, on the farm and in slaughterhouses for the implementation of a traceability system with automatic animal data capture. For this purpose a complete system for animal identification and tracking, accomplishing regulatory compliance as well as supply chain management requirements, has been developed and is described in the paper. Results were encouraging for identification of calves both in farms and slaughterhouses, while in swine breeding, identification was critical for small piglets. In this case, the design of a RFID gate where tag-to-tag collisions are avoided should be envisaged.

To lessen the threat of an intentional or naturally occurring livestock disease, the Animal Plant Health Inspection Service of the United States Department of Agriculture introduced the National Animal Identification System (NAIS), encouraging the use of innovative tools such as radio frequency identification (RFID) tags to track cattle across the country. In this study, the author examines the barriers to adoption of NAIS and RFID technology as risk-reduction tools. Diffusion of innovation literature is used to analyze a case study of a state livestock association advocating the rejection of NAIS and RFID technology. Implications for the diffusion of risk reduction tools are provided.

Data collected on 1438 male and 1492 female pure bred N'Dama calves calved between 1948 and 1961 at Fashola Stock farm were used to study the relationship between five N'Dama cattle linear measurements at pre and post Weaning ages. The measurements were Head to Shoulder (HDS); Shoulder to tail drop (STD); Height at withers (HTW); Heart girth (HGT) and Body length (BLT). All measurements had positive values which ranged from 0.2 - 91 except HTW and HDS which had a negative value (-02) in males at yearling age. There was a predominance of positive and highly significant relationship (P<0.01) between height measurement (HTW) and circumference measurement (HGT) which ranged from .04 - .76 with pre weaning measurements having higher values (.69 - .76) in both sexes. High and positive correlation values were also observed between length measurements (HDS, STD and BLT) which therefore shows that only one of such measurements is sufficient for length measurement Generally measurements taken at pre weaning had higher correlation values than those taken at post weaning.

AbstractIn 1998, the European Community, the Region Wallonne, and the Province du Hainaut funded the project known as the Centre for the control of animal health and its management (CESAM). This project was initiated in the Hainaut province of Belgium to answer problems encountered by cattle producers. Its overall goal is the identification of stages in the entire bovine production process where economic efficiency can be increased. A part of this project aims principally at the study of the impact of health-related problems on dairy production. For this part of the project, 32 veterinarians and 51 farmers started collecting data in the field. The methodology for data collection was based mainly on the harmony between the farmer and the veterinarian. Therefore, several procedures were implemented to ensure adequate motivation of both farmers and veterinarians. Farmers note all events of their livestock using a list, which contains disease events, preventive treatments, reasons for culling, and management practices. A veterinarian visits farms monthly to validate collected data and to discuss specific problems. During these farm visits, veterinarians collect body condition scores on adult cows. Veterinarians record also information on health problems they encounter during their normal practice using an international health data recording nomenclature. A national organization provides unique animal identification system. Production data will be recorded and feeding practices, milking procedures and barn comfort indices will be regularly investigated. All data will be collected on pre-printed documents, scanned at CESAM and centralized in a relational computer database. Criteria to evaluate the quality of the proposed methodology are presented.
