A Blueprint for Conducting a Veterinary Dairy Farm Audit

  Jos Noordhuizen

Farm situations and herd problems are commonly complex and multifactorial in nature. A dairy farm audit should therefore be well-structured and organized so that the farmer or veterinarian are not lost in their activities. This article presents a blueprint, a model, for conducting a dairy farm audit. For that purpose, an imaginary dairy farm and a herd problem was chosen: Metabolic disorders on a farm with 550 dairy cows. The subsequent steps in the farm audit are elaborated until the final farm audit report and veterinary advises, divided into priority advises and secondary advises

Assessment of the Reasons for Culling and its Relation to Age at Culling in Dairy Cows in and Around Mekelle City, Tigray, Ethiopia

  Idesa GD

Background: Culling is defined as the departure of cows from the herd because of sale, slaughter, salvage, or death. Culling is an important cost for dairy farms. At the same time, culling is a way to increase herd productivity and profitability, as keeping diseased and unproductive cows might result in lower herd milk production and deteriorated reproduction. In order to maximize profitability, the proportion of voluntary culling (selling for dairy purposes or culling due to low production) should be highest among the total culling rate. Previous studies indicate an ascending trend in the proportion of involuntary culling. This observational study used registry data of all cows from herds with ?5 cow-years in 2016-2017. Objective: This study was conducted to assess the reason for culling a dairy cow and its association with age at culling in and around Mekelle using a structured questioner format and direct observation. Visits were performed to each farm to collect data directly from owners or animal attendants and using direct observation. Materials and Methods: The cross sectional study was conducted in and around Mekelle city dairy farm from November, 2016 to April, 2017. Results: The most common causes of culling were disease and economic reasons. The most common causes of voluntary culling were economic reasons (17.39), low milk yield (20.29%), and aging (8.70%). The common causes of involuntary culling were diseases (34.78%), injury (7.25%), and infertility (5.80%). In this study rates of culling increased with parity. The highest rate of culling was in animals between parity 2 and 5, increased from (14.49%) to (21.74%) and slightly decreased from parity 6 to 7, i.e. (13.04) % to (8.70) %, respectively. The highest rates of culling were between 3 and 5 years, (17.39) % and (23.19) %, respectively. Conclusion: This study indicated animals were culled at premature age because of involuntary culling, which is economically not feasible, diseases were the most common causes of involuntary culling and voluntary culling was the most type of culling in dairy cattle farms and animals mostly culled for decreased production and economic reasons

Detection of a Brucella Melitensis Rev1 Vaccine Strain and Rev1-Like Strains in Unvaccinated Small Ruminants and Aborted Fetuses

  Boukouvala E

In this case study we report on the isolation of Brucella melitensis from two unvaccinated male animals (one ram and one buck) and from two aborted fetuses (lamb and calf). By applying both molecular and biochemical methods, investigating therefore the isolated strains at genus and species level they were classified in the case of buck as Rev1 vaccine strain while the rest three as Rev1-like since they exhibited some differences in their biochemical characteristics. It is worth mentioning that all the animals derived from intensively managed farm that had completely complied with the vaccination regiment

Consideration on animal nutrition in West Africa

  Maryline Kouba

In West African countries, the animal diet is poor because of the high price of major dietary ingredients such as corn and soya. However, these countries present a great biodiversity. The use of local plants not employed in human nutrition, available, free or very cheap in animal diets is a way to lower the price of the diet and to limit importations. We have used several plants first to give healthy meat and eggs (enriched by omega 3 fatty acids) with Euphorbia heterophylla supplemented diets in several poultry species, rabbit and guinea pig. Another experiment has shown that Heveabrasiliensis seeds meal can be used in pig and guinea fowl diets to replace soya without negative effect on performance. More research must be carried out to find plants as Heveabrasiliensis which can replace at least partly soyabean meal in animal diets to assure sustainability of small farms
