Introduction Phosphorus is an important nutrient for laying hens, e.g. for bone development and egg formation, but also plays an important role in environmental contamination. However, research on the phosphorus requirement of laying hens is dated (Van der Klis and Blok, 1997). The modern laying hen with a high egg number and laying persistency probably has a different phosphorus requirement than birds from 20 to 30 years ago. Furthermore, age and level of physical activity,...

Feeding of livestock is a scientific task to make all the nutrients available for maintenance, production, growth and reproduction. The right selection of ingredients for the optimum level of animal response is the least cost ration. The feeding of imbalanced ration would not only enhance the cost of production but also affect the health of the animal. It is a non contested fact that animal response is more crucial than ration computing. Therefore, the digestibility of nutrients in the...

Introduction The projected doubling of the human population by 2060 will require a 100% increase in food production coming from plants and animals with most of this increase coming from new technology and greater efficiency [1]. In animal production agriculture, feed is the highest input cost (50 to 70% of total) in raising an animal to market weight and feed costs can spike as observed during the severe drought in the US in 2012 [2]. Great strides have been made in animal...

ABSTRACT
The objective of this study was to evaluate the effects of a low-Ca diet, followed by a high-Ca diet in combination with feeding of anionic salts and/or vitamin D 3 on Ca and acid-base homeostasis of finishing steers. Twenty Hereford steers (448 _ 26 kg) were individually penned and fed at 0800 and 1600 with a ration consisting of 90% barley grain-based...

ABSTRACT
The objective of this study was to evaluate the effect of supplementing high levels of vitamin D 3 to steers fed barley-grain-based finishing diets on Ca metabolism. Fifteen Hereford steers (607 ± 12 kg) were individually penned and fed at 0800 and 1600 with a ration consisting of 90% barley-grain-based concentrate and 10% barley silage [dry matter...

Introduction Legislatures such as The Renewable Fuel Standard in the U.S.A. and The Renewable Transport Fuel Obligation in the U.K. have driven massive increases in bioethanol production from cereal (first-generation bioethanol). In 2011, the estimated global production was around 113 billion liters (OECD-FAO Agricultural Outlook 2012-2021). The rising volume of bioethanol production also results in increasing quantities of the current coproduct, distiller’s dried grains...

INTRODUCTION Temperature is the most important environmental factor in animal production and directly affects animal responses. Domestic birds are homeotherm animals and therefore must expend energy to maintain body temperature, in order to have adequate biochemical, physiological and behavioral responses (Al-Saffar, 2002). At high temperatures, the feather coverage is one of the factors that impair dissipation of the...

Introduction Poultry meat being a high quality animal protein source plays significant role in maintaining the health and nutrition of the people (Shahzad et al ., 2011). Along with broilers, 35.4 million spent birds (27.4 million layers and 8.0 million breeders) are also being used at the end of egg production cycle contributing more than 46,000 metric tones of poultry meat per annum in Pakistan (Anonymous, 2009; Mahmud et al .,...

There are multiple approaches a swine nutritionist can take in diet formulation: maximize performance, minimize cost, or maximize profit. Within each of these approaches, there are suboptions to decide from: Growth performance basis Maximize average daily gain (ADG) Minimize feed efficiency (F/G) Cost reduction basis Minimize cost per kg of diet Minimize feed cost per kg of...

Introduction In order to lower feed costs, crystalline AA are used routinely in swine diets to replace a portion of the soybean meal. The AA that are currently available to add to swine diets include lysine, threonine, methionine, tryptophan, and valine. The increased availability of crystalline AA sources has created the opportunity to formulate grain-based diets to the fifth or sixth limiting AA. If this can be accomplished without negatively affecting pig growth performance,...

Introduction India has a very large population of livestock both of productive and unproductive animals. Ruminants are mostly fed on low-quality roughages, which are poor in protein, energy, minerals, and vitamin contents. Addition of cereal and leguminous fodder in ruminant diets can improve the utilization of low-quality roughages mainly through the supply of N to rumen microbes. The ruminants can make efficient use of mill by-products, crop residues, and other...

Background After pigs are weaned from their dams, morphological and functional changes occur in their small intestine. Pluske et al. [1] reported decreased villi height and increased crypt dept. Because newly-weaned pigs are transitioned from milk to dry feed, the pig’s intestinal tract is unable to fully digest and absorb the more complex plant-based macronutrients in the feed. Various researchers [2,3] have reported that this accumulation of undigested and unabsorbed...
