Dairy cattle - Management practices

Welcome to the page about Dairy cattle - Management practices of Engormix; a source of knowledge on Dairy cattle - Management practices.
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 Decisions concerning the milking center are some of the most complicated decisions a dairy producer has to make. Milking procedures, herd size, expansion plans, milking interval and the equity position of a producer influence these decisions. One parlor will not meet the needs of all dairy producers. Producers will have to make the following decisions before they can select or develop management protocols for a milking parlor: 1. How many cows will be milked...

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...

Introduction Despite many advances in our knowledge of calf management, the dairy industry continues to be challenged with finding ways to raise replacement dairy heifer calves in such a manner that not only optimizes health, growth, and efficiency, but also is best for their welfare. This paper will identify some of those welfare challenges and how we can use knowledge of replacement dairy calf behavior to identify housing and feeding programs that optimize growth, health, and...

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,...

1. Introduction Goat production in Chile is carried out by poor small-scale farmers in semi-arid to arid agricultural conditions [1]. Milk and cheese are the main products obtained using artisanal, cultural and traditionally preserved methods where women and children are usually in charge of production [2]. The products are directly consumed by the family or sold to by-passers at good prices [3]. These production systems are similar in goat production around the world,...

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...

INTRODUCTION Raising healthy calves is the foundation for a sustainable and profitable dairy herd. Dam nutrition during the last trimester, calving supervision/assistance, maternity facilities hygiene, umbilical care of calves, colostrum management, and calf nutrition are important factors that impact calf development and health (Lorenz et al., 2011). Calf mortality of 5% or less has been suggested as target for calfrearing operations (Lanuza, 2006). In Chile, however, there is...

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...
