Global warming and the constant increase in cow’s milk yield exacerbate the summer problem in dairy farms and increase the production loss caused to milk producers. In order to quantify these losses, I collected data from five large scale high yielding dairy farms (1,500 to 3,000 cows per herd), located in the Torreon region, north Mexico, characterized by a desert climate, with close to 180 stressful days, where cows are exposed to heat stress conditions. Despite the desire to compare...

Summer heat stress is currently one of the biggest causes of economic losses to the global dairy industry, especially in the hot regions of the world. The International Dairy Federation (IDF) decided to deal with the problem and established recently an expert's committee to examine the issue and recommend ways to deal with it at the global level. After being recommended by the Israeli Dairy Board to participate in this committee, I found myself serving in a central role in...

Pneumonia of calves is a respiratory disease caused by the entry of bacteria and respiratory viruses into the body of calves, which occurs at the age of two to five months, and is more common in closed places and in the winter season. The best prevention of this pneumonia disease in calves is to give colostrum to calves. ...

INTRODUCTION The profitability of dairy farms is an increasing concern in many economies around the world (Ellis et al., 2020; Ojo et al., 2020). This is the result of continuous economic, political, social, and environmental factors affecting different countries and regions (O’Leary et al., 2018; Ramsbottom et al., 2021). Therefore, dairy farmers are continuously searching and updating strategies and technologies that can improve the dairy farm technical and economic...

Post-calving care for cattle is a critical phase in dairy farming that significantly impacts the health and productivity of both cows and their offspring. Proper care during this period is essential to ensure a smooth transition from pregnancy to lactation and to prevent potential complications. In this article, we will delve into the key aspects of post-calving care for cattle and why it is of utmost importance. Understanding the Significance of Post-Calving Care Calving...

Introduction Milk yield of a dairy cow depends on four main factors: (a) genetic ability; (b) feeding program; (c) herd management; and (d) health. As cows continue to improve genetically, we must also improve nutrition and management to allow the cow to produce to her inherited potential. A good dairy feeding program must consider the quantity fed, the suitability of the feed and how and when the feeds are offered. Dry Matter...

An article dealing with this topic was recently published in the prestigious journal of the dairy industry, Journal of Dairy Science (Espinoza-Sandoval et. al., JDS 106: 2023). The article examines, using a statistical model, the feasibility of investing in cooling the cows in the summer in various countries around the Mediterranean Sea (Europe, North Africa and the Middle East), where there are different “climate zones” regarding dairy farming. The model presented in this...

When talking about the negative impact of heat stress on milk production, we usually refer to the impact on milk volume (liters per cow per day or per lactation). The reality is that this is only part of the problem, which causes economic losses to farmers and dairy industry. As will be presented in this article, heat stress negatively affects milk fat and protein content and reduce milk quality, by increasing milk Somatic Cell Count (SCC) and bacterial count. In some cases, especially in...

Dear All, My friend is facing a problem on dairy farm..there is Watery Nasal Discharge,Hypersalivation,Normal temp.Milk production was slightly decreased but now its normal.Initially one of the aborted cows started showing these signs but that was high temp. and after that all other are showing these signs but with normal temp. please guide me what could be the possibilities and ways to manage this. feeding components are Silage,Green fodder,vanda,Gluten,mineral and soda...

I opened my own farm last year in North India. I have a herd of 150 HF cows and I bought all the cows in advanced pregnancy stages. I had good results in calving and milk. Then we started the AI of them as per the normal practice i.e. as per the visible heat and also used synchronization using protocols based on receptals. Now I have 10 cows which are not getting pregnant and are almost at the point of being dry. So neither I can sell them (nobody would buy them)...

Heat stress related production loss, compromised welfare and cattle mortality are global concerns, which are increasing in the context of climate change and increase productivity of the cows. Cattle response to heat stress varies, based on individuality and thermal environment. In this article I intend to describe heat stress monitoring, in individual and herd basis, making use of thermal indices, as well as physiological and behavioral changes occurring in the heat stressed cow. 1....

Heat stress related production loss, compromised welfare and cattle mortality are global concerns which are increasing in the context of climate change and global warming. To maintain the welfare and performance of livestock, monitoring the effects of climatic extremes is important. Farming systems are becoming increasingly automated and remote/automated monitoring of animals is an ultimate need to overcome the limitations of human observation for continuous characterization of cows...

Introduction Downer cow syndrome (DCS) is defined as lateral or sternal recumbency that persists for longer than 24 hours [1], or that persists for longer than two weeks despite of treatment [2]. The incidence of this syndrome ranges from 4.5 to 14% [3]. Downer cow syndrome can be seen in all stages of the animal’s reproductive cycle but the majority of all downer cows are diagnosed shortly after parturition. A multitude of metabolic, infectious, toxic, degenerative and...

Introduction The metabolic cages are used to study the metabolism of feeds in the animal. Metabolic trials are conducted to collect the feces, urine and feeds residue using precisely for analysis nutrients intake, digestibility, nitrogen and mineral balance. It is generally conducted in confined shed/shelter with underground place for urine collection. It is observed that due to movement of animal urine collection pipes comes out of the drum resulting in loss of urine. In this...

INTRODUCTION Early detection of mastitis is considered to be the best method to allow the cows the best chance for prompt recovery. Most farms base mastitis detection on visualization of clinical signs such as swollen quarters or altered milk. However, on large farms that have hired workers for milking it may prove challenging to have good mastitis detection. Therefore, new technologies are being constantly tested to automatically detect mastitis in the milking...

INTRODUCTION Milk conductivity has been evaluated for mastitis detection in the past without a clear picture of how it works. The information shown in this descriptive study shows the normal variation that occurs throughout the lactation in dairy cows. MATERIALS AND METHODS Data from different farms was used for this study. All farms had milk meters equipped with conductivity probes (Afimilk, Israel). Cows were automatically...
