Abstract:

The objective of the present review was to establish levels of conserved fodder wastage when feeding livestock (sheep, beef cattle, dairy cattle) under various conditions and using various feed-out systems, and to determine the factors affecting wastage. The mean wastage of hay recorded in the literature reviewed was 17% of the DM offered, but the range was from 4 to 77%. The main factors affecting the degree of wastage were storage method, packaging method, method of feeding out, amount of fodder on offer and its palatability and/or quality and the impact of wet weather.

Abstract:

In the last decades we have witnessed increasingly pronounced climate change worldwide resulting in environment transformation in various regions by making it not convenient for agricultural and livestock production. The global livestock sector contributes to anthropogenic greenhouse gas emission, but on the other hand, it can also deliver a significant share of the necessary mitigation effort. One of the most significant greenhouse gas is methane. Mitigation methods for the methane emissions in cattle can be classified as short and long term. Short-term methods imply increase of production pe

Abstract:

The evolutionary and domestic ancestors of sheep and cattle will have evolved diet selection behaviours that enabled them to select a diet that met their individual nutrient requirements whilst minimising the risk of being killed through predation or by eating toxins. Modern intensive farming generally involves grazing monocultures or feeding total mixed rations and these restrict the ability of livestock to select their own diet. Research has shown that grazing sheep and cattle have a partial preference of approximately 70% for clover (when offered as a monoculture sward alongside grass), and

Abstract:

Heat stress plays a role in livestock production in warm climates. Heat stress conditions impair animal welfare and compromise the productive and reproductive performance of dairy cattle. Under heat stress conditions, dairy cattle modify their behavior. Thus, the assessment of behavior alterations can be an indicator of environmental or physiological anomalies. Moreover, precision livestock farming allows for the individual and constant monitoring of animal behavior, arising as a tool to assess animal welfare. The purpose of this study was to evaluate the effect of heat stress on the behavior

Availability and access to fresh water will likely constrain future food production in many countries.

The main objective is to identify technologies that will help enhance LWP.

Promoting feed intake of lactating dairy cattle (particularly those in early lactation) is critical in terms of improving milk production, health, body condition and welfare of the animals (Grant and Albright, 1995).

Feeder design and stocking density can have a major impact on feed intake and aggressive behaviour; therefore it is an important consideration when designing housing and managing livestock.

Abstract:

Background: Animal feed is one of the main determinants of livestock production costs. Tofu dregs and dry-cooked rice waste is favoured by farmers as an additional feed for cattle because it is readily available and inexpensive. Tofu dregs and dry-cooked rice waste is considered to be able to provide adequate nutrition for cattle and is believed to be able to be a factor in increasing cattle daily body weight. The efficiency of feed use can be determined from feed conversion, namely the amount of feed consumed to achieve an increase of one kilogram of body weight. Purpose: To find out the aver

Abstract:

Recently, a new genotype of oat has been developed specifically for feed purposes by the Crop Development Centre called CDC SO-I (“SuperOat”) containing a low-lignin hull and a high-fat groat. However, no quantitative evaluation of protein supply from CDC SO-I to dairy cow has been done in terms of potential protein degradation balance (PDB) and total metabolizable protein (MP) supply. These data are crucial in order to develop more efficient, competitive and optimal feeding the new genotype of oat (CDC SO-I) for livestock.

Abstract:

Efficient liveweight gain is an important component of profitable livestock systems. In cattle, studies of residual feed intake (RFI) suggest that there are behavioural differences between efficient and inefficient animals; more efficient animals have less frequent, larger feed events. There is limited understanding of the association between feeding behaviour and feed conversion efficiency (measured as RFI) in sheep. We hypothesised that more efficient sheep would have lower daily number of meals but larger meal size than would less efficient sheep and that feeding behaviour would be repeatab

The nitrate (NO3) method requires that each baseline area must demonstrate a history of urea use.

The contemporary concern about anthropogenic release of greenhouse gas (GHG) into the environment and the contribution of livestock to this phenomenon have sparked animal scientists’ interest in predicting methane (CH4) emissions by ruminants.

Focusing on milk production, we address six basic nutrition models or feeding standards (mostly empirical systems) and five complex nutrition models (mo

However, gaseous byproducts from ruminant production systems, such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) are deleterious to the environment. It is estimated that CO2, CH4, and N2O from managed waste and grazed lands account for roughly 54% of emissions f

A 3 x 2 factorial experiment was initiated to observe effects of a mycotoxin binder, hydrated sodium calcium aluminosilicate (Engage-M, United Animal Health, Sheridan, IN), on cattle performance. Three treatment diets with elevated mycotoxin levels were amended with Engage-M fed at 0 or 14 g hd-1 d-1. S
