INTRODUCTION Today’s dairy farms are changing dynamically, with increasing herd size and more hired employees. On larger U.S. farms, there is a reliance on non-family immigrant or contract laborers. Latinos have surpassed African-Americans as the nation’s largest minority group, constituting 17% of the U.S. total population in 2014 (1). This is reflected within the dairy industry, and the increasingly Latino...

Summer losses in milk production are usually related to the negative impact of summer heat stress on the lactating cow. Actually, this is true, due to the large negative effect of heat stress on feed consumption and the efficiency of feed utilization of the lactating cow, as well as on reproductive traits. Recently, it was found that also dry cows, although they are not producing milk, are negatively affected when subjected to heat stress conditions, mainly, due to lower milk and milk solids...

Livestock sector has been considered back bone of Indian farmers. India has cattle and buffalo population of 190.90 and 108.7 million respectively which are major contributors of milk production in the country (19th livestock census, 2012) but, the productivity of our animals are not at par with that of exotic animals. However, it can be improved by better management.
New concepts of dairy farming managerial practices are coming into force these days with their varied benefits. One...

As herds aspire to achieve higher levels of milk production there is a need for more focused management of all areas of the farm. The management of the milking center is no exception to this. In order to achieve success with the milking center the first step is to document what the current baseline is for all the major areas affecting the milking center. During the analysis of this baseline data one important distinction to make is whether the opportunity areas...

Introduction The practical and scientific knowledge obtained on the use of the Lactoperoxidase system (LPs) confirms its innocuity to human health (1), which allowed the lifting of the restriction that the system could not be used for milk products intended for international dairy market, in the Thirty-Second Session of the Commission Codex Alimentarius (2). The simple name of LPs generates confusion due to the association to hydrogen peroxide or oxygenated water, adding without...

Introduction The many hormones, growth factors and cell types involved in bovine mammary gland development and lactation make the elucidation of their roles difficult; a representative in vitro model of lactation would help in this regard. Previously we have isolated a mammary epithelial cell (MEC) clonal line that can undergo three-dimensional morphological and functional differentiation when cultured on a reconstituted basement membrane (McConochie et al., 2004). However, the...

Biosecurity means reducing chances of spread of infectious diseases at animal farm by animals or humans or by any other means. Biosecurity reduces the risk of infectious diseases at the farm. By management interventions we can do this.
Presence of infectious agent in an environment where the animals reside, may lead to cause disease in them under favorable conditions. That’s why; it becomes very necessary for livestock producers to take a...

Misconceptions Animals have to suffer on large confined operations. Abuse is rampant. Large herds only can exist through widespread use of antibiotics and hormones. Large farms pollute rivers. Meat and milk are laden with drug and hormone residues. Large operations exploit animals...

Cooling means to reduce heat stress from cows have been developed over the last four decades in Israel, 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. Cows are usually forced ventilated in resting area, if it is in free stalls or compost...

Introduction The major use of rangelands is grazing or browsing by livestock and wild herbivores. Semiarid and arid rangelands are often fragile and subjected to accelerated soil erosion if not managed appropriately. If rangelands are mismanaged, so that plants fail to provide sufficient soil cover, the composition of plant community changes, resulting in reduced productivity and increased erosion. Continued abuse of the rangeland system can also result in severe land...

Benefits of early detachment Faster milking. Early detachment reduces machine-on time. This may or may not result in milking more cows per hour depending on parlour size and milking routine. AMS benefit the most from a short machine-on time. Calm cows. Several studies have observed calmer cows when detaching at a higher flow rate. First lactation cows seem to be more sensible to overmilking than older cows. Improved teat...

INTRODUCTION Digital dermatitis (DD) is a widespread bacterial foot lesion in cattle that typically develops on the bulb of the heel, causing ulcerative lesions that may be uncomfortable or very painful (Cheli and Mortellaro, 1974; Döpfer et al., 1997). It is the most common foot lesion in confined dairy systems, with a prevalence ranging from 15 to 49% (Holzhauer et al., 2006; USDA, 2009; Solano et al., 2016) and...

Introduction Heat stress causes major losses ($ 2.4 billion) in animal production, including dairy cattle, beef cattle, swine and poultry in the USA (St-Pierre et al., 2003). Heat stress affects feed intake, body temperature, maintenance requirements and metabolic processes, feed efficiency, milk yield, reproductive efficiency, behavior and disease incidence (Cook et al., 2007; Tucker et al., 2007; Rhoads et al., 2009). Water is necessary for a proper rumination and digestion...
