Managing Air and Heating for Quality Silage 

Silage quality is made up of not just the nutritional quality of the crop when it is cut, but also the fermentation and hygienic quality. Managing air is a critical step in reducing damage and losses in silage caused by these ‘bad bugs’ or spoilage organisms that thrive on air. Getting rid of the air […]

In a Pickle with High Acetic Acid Silages

The goal of ensiling a forage crop is to conserve as much as possible of the nutrient and dry matter (DM) content in the crop at the time of harvest. Lallemand Animal Nutrition specialists say the ensiling process is actually quite simple: Chopped forage is packed in a pit to exclude the air, lactic acid [...]

Transition Cow Nutrition

Various factors contribute to the profitability of any New Zealand dairy herd, production, longevity, fertility and cow health could all be considered key factors. Managing a successful transition period is a key element to achieving all these factors. Poor feeding and management during the transition period can result in a host of problems around calving [...]

Benefits of Calf Rearing Supplements

Trials in NZ and overseas have demonstrated the long term benefits of good calf rearing in terms of improved production and health. Freshly born calves have yet to develop their immune systems, so rely initially on antibodies in colostrum for early protection against potential pathogens. However, this does not provide complete protection, especially during periods [...]

Transition Cow Feeding and Management

A significant proportion of any herd’s health and welfare costs can come from the 3 weeks pre-calving to the 3 weeks post-calving. This is the period where the cow lays down the building blocks for the coming lactation, so minimising metabolic disease and implementing a system to reduce negative energy balance and maximise post-calving dry [...]

Silage Inoculants for Maize & Whole Crop Silages

Last month’s article considered principles and techniques for making high quality maize and whole crop silages, including the use of appropriate inoculants. The preference until fairly recently was to rely on homofermentative lactic acid producing bacterial inoculants, due to lactic being a strong acid so aiding rapid fermentation thus lower dry matter losses than untreated [...]

Ensiling Maize & Whole Crop Cereals

Silage making is about preserving as much high quality forage as possible, especially when grown on one’s own farm, as it is a major contributor to farm profitability. This starts with harvesting the crop at its optimum quality and yield, retaining as much of it as possible, and feeding it out efficiently by minimising losses [...]

Managing Heat Stress

Heat stress occurs when cows are unable to control their body temperature at high temperatures, which leads to reduced feed intake, rumination, rumen function, milk yield and milk fat and protein levels, and increased respiration rate and risk of acidosis. The higher the relative humidity (RH) the lower the temperature at which heat stress occurs, [...]
