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...

Summer heat stress negatively affects the dairy sector in Italy by harming animal welfare, increase environment pollution and reduce farms profitability. The decrease in farm profitability is caused by the decrease in cows annual milk production (feed and other expenses per liter of milk are increased when daily production is lower), reduction in milk quality (lower fat and protein content and increase in SCC), direct decrease in feed efficiency (when part of the feed energy consumed...

As this is written (Winter, 2012) feed prices continue to hover around historic highs and although milk prices have risen they have not kept pace with the increases in feed costs. Feed costs are usually the largest single expense on a dairy farm and with well-above average feed costs, the feeding management and nutrition of the dairy herd must be scrutinized now more than ever. ...

Introduction The challenge of the contemporary production of agricultural products is intrinsically linked to optimizing processes and production costs. Ensuring thermal comfort, considering that the intense incidence of solar radiation and the high temperatures observed practically throughout the year in the Brazilian semiarid region can cause stress, causing the animals to decline in production, can increase animal production (Leitão et al., 2013). Therefore,...

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,...

This article presents the results of a "cow cooling project", in northern Mexico, characterized by long hot and dry summer months, with the extreme conditions of heat stress in dairy cows. The farms where the cooling project took place are considered as large scale dairy farms, with high-yielding cows from the Holstein breed. The dairy farmers are aware of the existence of a negative effect on the indices of summer production, reproduction and health of the cows and the economic losses...

INTRODUCTION Grazed pasture soils are a potential source of nitrous oxide (N 2 O) due to elevated inorganic N pools. N 2 O is the dominant source of microbial denitrification, and under suitable conditions, N 2 O may be reduced in the soil to the environmentally harmless di-nitrogen gas (N 2 ). One of the key nitrogen (N) sources is urine deposited from grazing animals. The loading rate of N in a cow urine patch is determined by the dietary N...

Over the past two decades research in milking management has focused on decreasing the time that units are attached to cows by researching optimal teat stimulation and prep-lag time, pulsation ratios and liner compression and raising automatic take-off settings.
Optimal teat stimulation and prep lag time
Prep Lag time is the time from the start of teat stimulation, to milking unit attachment.
Nearly 50 years ago (1980) Ram Sagi achieved, a higher milk...

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...

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.

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...
