INTRODUCTION Producing food from farmed animals is a large and very complex process that occurs in integrated networks made up of many individual animal producers, supporting businesses (veterinarians, feed suppliers, animal haulers, animal marketers, etc.), and processors (slaughter plants) (1–4). Farmed animal food has many names including Agri-Food systems, food animal value chains, food supply chains, livestock production systems, and others. For simplicity...

Trace elements are required for numerous metabolic functions in livestock. Optimal production and performance require adequate intake of balanced trace minerals. As trace mineral status of the animal declines from adequate to marginal, immunity and enzyme functions are compromised followed by the loss of performance and reproduction. ...

Introduction Animal-source feedstuffs are generally superior to plant-source ones for the growth and health of livestock, poultry, and fish (Wu 2018). This is due, in part, to the greater quantity of proteinogenic amino acids (AAs) and higher quality (the ratios and digestibilities of AAs) of the former than the latter. Traditionally, extensive research has focused on AAs that are not synthesized by animal cells and are known as nutritionally essential AAs (EAAs), including...

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.

Feed mixing and delivery is one of the most important activities on the dairy. Mixing and feeding a total mixed ration (TMR) is a multiple-times-per-day activity. Doing this job accurately and consistently time and time again, batch after batch and day after day is critical to production (volume and components), animal health and overall farm economics.
Accuracy and consistency of mixing and feed delivery may be one of the greatest effectors of production and feed efficiency on the...

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 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...

Introduction
Milk is one of the most important foods of human beings and is recognized globally as a complete diet due to presence of essential components required for human health. India has a good number of dairy animal populations which plays an important role in economy of the country. India continues to be the largest producer of milk in the world (19% of the world’s total milk production) with annual milk production of 176 million tons in 2017-18(BAHS,...

Introduction The rise in milk production has been accompanied by increasing incidence of health problems, declining ability to reproduce and declining the fertility of modern dairy cows. The transition from late gestation to early lactation is viewed as one of the most challenging elements of the production cycle. Perhaps the most important physiological change occurring during this period is the decrease in dry matter intake around...

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...

Introduction The transition period into lactation remains one of the most challenging and important phases of the production cycle in a dairy cow. It is a transient period around calving characterised by drastic changes in the hormonal status, 2 to 5-fold (Bradford, 2020) increases in nutrient demand and apportioning of 85% of body glucose to the mammary gland. Simultaneously, the requirement for specific fatty acids escalates by more than four times (Bell, 1995; McFadden and...

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...

1. Introduction Mycotoxins are secondary fungal metabolites that are harmful to animals and humans [1]. Monogastric animals are considered to be more susceptible to the toxic effects of mycotoxins than ruminants as the rumen microbiota are capable to degrade some of those toxic molecules to less toxic metabolites [2–4]. In addition, intrinsic rumen fluid factors, such as bacterial and yeast cell walls and feed particles, can deactivate mycotoxins (e.g., aflatoxins and...

Introduction The dominant primary plant formation in the Cacaueira is a dense ombrophilous forest, known like Atlantic rainforest or simply Atlantic forest. This biome is found along of the Brazilian coast, covering the coastal plains and eastern slopes of the Serra do Mar and Serra General, at altitudes of up to 600-700 m. The Forest Atlantic had as its basic characteristic, luxuriant vegetation, high and developed, whose structure and composition varied by region; presented...

INTRODUCTION Bovine viral diarrhea virus (BVDV) has been classified within the genus Pestivirus of the family Flaviviridae (Wengler et al., 1995). It has a positive single-stranded RNA genome of approximately 12.3kb size, encoding one open reading frame (ORF) that is translated into a single polyprotein of about 4000 kDa (Collett et al., 1988; Meyers and Thiel, 1996). The polyprotein is subsequently cleaved into 4 structural and 6 to 7 non-structural proteins by viral and...

THE PHASES OF THE RAISING PROCESS
Under intensive systems, the stage called Calf Rearing lasts approximately up to 60 days (30-60 days) and has three important phases:
1. Pre-ruminant phase - in which the main food is in liquid form, such as milk or a milk replacement. During this phase, the abomasum or true stomach fulfills the main digestive functions.
