Summer heat stress has been considered in these days as one of the greatest causes for losses in the world dairy sector. Italian Breeders Association (A.I.A.), adopted the Summer to Winter ratio (S:W) index, a heat stress assessment tool based on the ratio between summer (July – September) and winter (January – March) farm performances. S:W ratio has been developed in Israel and adopted recently in Italy and other countries, as a tool for detecting performance pitfalls in summer...

Introduction The nutritional management of young dairy calves can have both short- and long-term effects, from influencing morbidity and mortality rates (Urie et al., 2018a) to reproductive efficiency and first-lactation milk yield (Faber et al., 2005; Soberon et al., 2012; Gelsinger et al., 2015). Although major improvements in calf nutritional strategies have been made over the past decade, dairy calves continue to suffer from the highest rates of...

Background Providing adequate amounts of essential minerals is critical to maintain health and maximize productivity of dairy cows (NRC, 2001). Organic minerals can be described as nutritionally essential minerals attached to a carbon–hydrogen based molecule which acts as a ligand. Ligands that are used most frequently include amino acids, peptides and proteins. In particular, complexes where a mineral is bonded to amino acids with at least two bonds from each amino acid...

Adult lactating cows receive more attention when it comes to the negative effects of heat stress, as compared to heifers. This is because lactating cows need to dissipate more heat, running out of milk production and feed consumption and digestion to support it. The losses, caused by exposing adult cows to heat stress conditions include drop in milk production and composition, fertility, health and cow's performance in the subsequent lactation, when exposed to heat stress conditions in...

Introduction Although several species of parasites are harbored in the gastro intestinal tract of animals only few species are clinically and economically important. Clinically important parasites of farm animals prevalent in tropical conditions like Chitwan are Paramphistomum Spp., Fasciola Spp., Toxocara Spp., Monoeiza Spp., Ascaris Spp., Taenia Spp., Haemonchus Spp. and other different nematodes species. The major problem associated with Gastro intestinal parasitic...

Introduction At birth, the rumen is non-functional, making calves pre-ruminants. By weaning, the rumen is the principal site of volatile fatty acid (VFA) absorption, responsible for over 50% of all VFA being absorbed (Allen, 1997). Consequently, the calf rumen must undergo a ruminant transition, where the rumen goes from non-functional to functional in 6-10 weeks, coinciding with the period when most dairy calves are weaned (USDA, 2012). The transition...

Introduction Coccidiosis is an infectious disease of the intestinal tract of wild and domestic animals caused by different protozoa. These include but are not limited to Isospora, Neospora, Cryptosporidium, and Eimeria of the phylum Apicomplexa. Those parasites are widespread, especially where intensive production systems are used to raise livestock. They cause mortality, poor growth, and impaired performance. In addition to mortality and reduced growth, coccidiosis also affects...

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.

For the last few months, it seems that immunity has been at the forefront of our thought process – not just for the dairy industry but world-wide. While everyone has been focused on staying healthy and have become increasingly aware of the importance of a well-functioning immune system (IS), these are concepts that the dairy producer needs to keep in mind almost every day.
The IS in all animals is critical and complex. Life is dependent on a functional IS. Its primary function...

Dear Users, This is an interesting forum from our Spanish community, generated by Enrique Astorga from Canada: As a dairy farmer if you should take a hit of over 80 of mastitis treating the problem without resorting to antibiotics, is to leave your old practices using antibiotics or try to see other alternatives? What would you say if you have 90 success in treatment? Many dairy farmers in North America are in the search for alternative treatments without...

Introduction Bovine respiratory disease (BRD) is the most important cause of economic loss of the beef industry in many parts of the world (12, 14, 26). It is a multifactorial condition that involves host and environmental factors, and several viruses and bacteria. The most common viruses associated in cattle with BRD are bovine herpesvirus (BHV-1), bovine parainfluenza virus 3 (BPIV-3), bovine viral diarrhea virus 1 and 2 (BVDV-1/2), bovine respiratory syncytial virus (BRSV)...

According to the severity of twisting, it is decided to apply a rolling method or surgical treatment to correct uterine torsion in time, return to the normal anatomical position and ensure calving smoothly. Conservative treatment "Rolling Maternal Method" to correct uterine twist: lay soft grass on the broad flat ground lay down cows, tie the forelimbs and hind limbs with ropes respectively, leaving about 100 cm of rope head. The cows lie on the same side of the uterus twist and pull the...
