In recent years, adjustments to the production costs in the dairy industry becomes crucial in light of current circumstances. There has been a continuous reduction in profit margins and increasing instability in this industry. Each stage in the production process requires maximum efficiency from both professional and economic points of view. The calf rearing stage is an integral part of the dairy business, and takes large part in determining the future quality of a dairy herd.

Nowadays that pandemic is of actuality some epidemiology lessons can be extracted to understand lameness prevention. To address lameness prevention in an academic way we must follow the basis of preventative medicine stablished by Wirchow based on 3 steps: There are 3 level of prevention: 1 Avoid disease appearance 2 Minimize clinical expression 3 Treat clinical cases to minimize severity Level 1 Starts since the decision of...
Q: What are the main consequences of heat stress? A: Regarding milk production, there are different factors, not just volume, but also fat content and protein in the milk and quality of the milk;...
Cooling means to reduce heat stress from cows have been developed over the last four decades in Israel and around the world, and are applied to a different degree of success in many farms in the world. Cooling cows in the farm is based largely on the daily routine, which includes cooling the cows in the waiting yards before and between milking sessions, as well as in the feeding line, around feeding time. In farms with robotic milking, there are no milking hours defined, and each...
1. Data The dataset in this article describes the new water footprint for animal products in fifteen countries of the Middle East and North Africa. Fig. 1 presents the methodology for calculating the local and imported green, blue, and grey water footprint of animal products. Fig. 2 shows the weighted average water footprint (WF) of feed items disaggregated by source (local and imported fractions), and by type (green, blue, and greywater). Fig. 3 shows the WF of an animal...
Introduction The very word behavior doesn’t comply with humans only, it is with animals too. Animals, as humans do, also have their typical feeding habits. They behave in different manner to different feeds. Ethology is the name given to the science that deals with animal behavior. Better understanding of Ethology helps us to make better and efficient feeding management which is an inevitable part of a farm operation. Types of ingestive...

Introduction As any other Latin American country, bovine brucellosis is a significant animal health problem and a relevant zoonosis in Costa Rica (CR). Consequently, the disease is of veterinary and of public health relevance. Bovine brucellosis (then recognized as “Bang´s disease”) was clinically described in the Central Valley and in the volcanic highlands at the end of the XIX century, when different breeds of cattle were imported from United States and...
1. Traditional tethered feeding: Mainly centered on cowshed, feeding, resting and milking cows on the same bed. The management of dairy farms is parallel to each other, and a personnel contract is adopted in the mode of the management contract. That is to say, each person contracted 15-25 cows. The feeding, milking, and excrement of these cows are all under the responsibility of one person. Its advantage is that feeding management can be refined. The disadvantage is that it is laborious,...
Summer losses in milk production are usually related to the negative impact of summer heat stress on the lactating cow. In the last 40 years, some studies realized in different parts of the world showed that also dry cows are negatively affected, when subjected to heat stress conditions. These losses are mainly related to lower milk volume and solids production, as well as fertility traits in early stages of the subsequent lactation. Heat stressed dry cows also suffer from higher incidences...
1. Introduction Crop husbandry and animal husbandry are two main pillars of Indian agriculture which play crucial role in Indian economy. Animal husbandry particularly dairy development has great potential and prospects for eradicating rural poverty and bringing the rural masses above poverty line. Dairy development can provide employment opportunity to earn livelihood for weaker strata of society [17] and also improve their nutritional status through milk consumption. The major...
In a survey that we carried out recently in Israel, we found a great variation between farms, in terms of the number of hours along the day the cows are in "heat stress" condition (body temperature above normal). This variation is correlated with cow’s milk yield and breeding performance during summer months. As time in a day, cows face heat stress is longer, the drop in milk production and conception rate in the summer (as compared to winter levels) is greater. In this article,...
Climate change is one of the most important environmental realities that human faces in this century. Not only because of the effects it has on the different human spheres, but because it represents a challenge for the development model that human has assumed since the industrialization period (Estenssoro 2010 and Lemaire et al. 2019). High temperatures and variations in the relative humidity of the environment are common in tropical summers and are considered as the most influential...
In a lecture I gave at the 29th Israel Dairy Conference, held in Jerusalem in November 2017, I presented the principles of my work in consulting dairy farms around the world on coping with negative effect of summer heat stress, and the achievements we reached in different countries due to the correct implementation of cow cooling methods. At the beginning of my lecture, I presented the basic conditions for obtaining the best results from cooling the cows, in projects in which I operate,...
Introduction In field conditions, body condition scoring has been accepted as most satisfactory tool for easy judgment of dairy animals for their energy status as compared to the laboratory methods like estimation of plasma NEFA, BHBA, glucose, urea, protein, etc. but they are laboratory methods which require a well-equipped lab facility, and it is expensive too. BCS is a method commonly used to determine negative energy (NE) balance and in conducting appropriate nutrition...
The organizers of the upcoming Animal AgTech Innovation Summit spoke to Lyndsay Chapman, Chief Executive at Centre For Innovation Excellence in Livestock about improving animal welfare, maximising animal health interventions and the benefits for animals, farmers and consumers.
