Hi, I just want to have information about guar korma. is it used to feed dariy cattle? If yes how many kilos of it should be used per animal? I have heart that it is used by some feed mills in Turkey. But I have another information that it cause milk yield deppression? ...

Global demand for animal proteins is foreseen to increase by 22% (Figure 1). Thus, one of the main challenges for 2050, in addition to meeting the high expectations in terms of food production, is facing the various issues which threaten food quality and safety, as well as land management and sustainable beef production. This will directly influence how we will raise and feed our animals to meet consumers needs. ...

Since mid-1980s fertility of UK dairy herds has declined year-on-year as is evidenced by the current calving interval of around 420 days. To put it into perspective, NMR in 2010 estimated the cost of fertility in an average dairy herd of 100 cows was around £25,000 per year. This included lost milk output, excessive culling and attendant veterinary costs. It is argued that genetic selection for high milk production has compromised fertility. Although this...

1. Introduction In the agricultural areas of Venezuela, specifically in Píritu municipality, the main problem in animal nutrition is the energy component of balanced rations, due to the inadequacies of this nutrient and the high cost per unit of energy produced locally. At present, the demand for items used as ingredients for the production of animal feed, such as sorghum is covered up to 60% with imports, as well as 95% soybeans. Because, on the one hand, the...

Feeding fat and fat products to dairy cows is common on most, if not all, dairies. Understanding how to properly feed fats and fat products is another story and seems to change daily.
This is especially true as we work to understand the roles various fat components (fatty acids) play in the animal in terms of production (volume and components), health and reproduction.
And while it may not be necessary, let’s remember that fat feeding in the dairy animal is broken into...

Abstract This paper discusses the definition, methods, advantages and disadvantages of microencapsulation, and identifies the improvements achieved in animal nutrition with the advent of microencapsulation. Microencapsulation is used to improve product bioavailability, delivering nutrients and additives to the digestive tract at varying rates or sites of delivery with an aim to improve animal performance. Several techniques used for microencapsulating feed ingredients will be...

The optimisation of the use of nitrogen (N) in ruminants diet can be highly valuable in terms of profitability and sustainability of any farm. In this study it has been assessed the use of economical source of nitrogen in combination with natural plant extracts, mainly tannins, which can influence protein metabolism in the rumen. Ruminants can make use of certain non-protein nitrogen (or NPN) compounds, some of...

Background Carinata (Brassica carinata) is a new oilseed that shows great potential for the Midwest. This oilseed has been selectively bred for high oil concentration ideal for biofuels and bio-oil production. Carinata meal is the co-product resulting from the oil extraction of the seeds. This meal has high protein content (36-48% crude protein), highly degradable in the rumen, and with a total digestibility of the protein a...

Introduction Proper sampling of ration ingredients and submitting those samples for nutrient analysis to a good lab are essential components of diet formulation. The relative importance of sampling, analytical, and real variation on overall variation in nutrient composition data of ingredients has been discussed at previous conferences (Weiss et al., 2012; Weiss et al., 2014). Sampling variation was an equal or greater source of variation than was real month-to-month...

Going from the late dry period to early lactation requires an incredible adaptation of the cow’s metabolism. No period of her life is posing more physical and physiological challenges - with important consequences for her health. The energy requirement increases within days by factor 4. Energy intake via feed is not able to follow so the cow gets into a negative energy balance (NEBAL). That means she is starving. This condition can last up to 100 days....

The addition of yeasts as additive in ruminant diets has favorable effects on microbial population and on the ruminal fermentative indicators. Consequently, health and productivity of animals are improved (Stella et al. 2007 and Doleža et al. 2011). There are multiple products in the world market in which commercial strains of Saccharomyces cerevisiae yeast are employed as activators of ruminal fermentation (Chaucheyras et al. 2004). However, there are not plenty studies showing the...

Introduction Some 2.6 million hectares are cultivating in the world, where the greatest use of cactus for forage or fodder occurs in Tunisia: 600,000 ha, Algeria: 150,000 ha, Mexico: 230,000 ha (39), South Africa: 525,000 ha and Ethiopia: 355,000 ha (46), Brazil: > 600,000 ha (50) and Southern Morocco regions: 90,000 ha (1). For Argentina there is information on area cultivated with Opuntia only for fruit production: 2,000 ha in 2003 (44). The major limitation to cultivation...

Introduction The use of exogenous enzyme supplements for dairy and beef cattle has received much attention during the last several years. Research efforts have mainly focused on the application of fibrolytic enzymes as feed pre-treatment agents or as direct-fed supplements. Direct feeding of exogenous enzyme preparations is more practical and is supported by studies showing high stability of fungal carbohydrases in rumen fluid (Hristov et al., 1998; Morgavi et al., 2000) and...

INTRODUCTION In the past 30 yr, one of the strategies to supply dietary minerals for dairy animals was to cover a high proportion (50 % or more) of dairy animal requirements with a mineral mix composition with minimal or, in some cases, no consideration of mineral content in the other dietary ingredients, i.e. forages, grains, and byproducts. In some cases, data from NRC and mineral chemical analysis...

Introduction: Dairying has been considered to be one of the livelihood options for rural poor people, especially for landless, marginal, and small farmers in India and world. Generally, the productivity in dairy sector is low and smallholders are constrained by lack of access to quality feed. Although professionals have pointed out the importance of feeding, the ground realities or practices about concentrate feeds is entirely different. Due to shrinkage of grazing land and...

Fat found in milk originates from three sources; de novo fatty acids synthesised in the milk gland of the cow (short-chain C4 to C14) comprise about 20-30% of total milk fatty acids, preformed fatty acids (long chain C18:0, C18:1 and C18:3) represent 35-40%, and the mixed group of fatty acids (C16) make up about 35%.
Research has shown that the percentage of milk de novo fatty acids is positively correlated with the percentage of fat and true protein in the milk. It has also been...

ABSTRACT Coproducts of n-3 fatty acid production from algae are a potential feed resource for cattle. A study was conducted evaluating feeding algal biomass to cattle. Crossbred cattle (20 steers and 20 heifers, 255 kg initial BW, SD = 14) were individually fed 4 inclusions of condensed algal residue solubles (CARS; 0, 2.5, 5, 7.5% of diet DM) displacing dry-rolled corn in the finishing diet for a minimum of 97 d. Increasing CARS inclusion in the diet quadratically increased DMI...
