Environmental issues are a growing concern within agriculture. Several of them can be categorized under the following headings: manure storage and handling, air quality, manure nutrient concentrations, and amounts of soil nutrients. Recently introduced, EcoCare feed (Land O'Lakes Purina Feed LLC, Shoreview, MN) is a dedicated and affordable feeding program addressing manure management, ammonia emissions, and nutrient excretion while optimizing pig performance. Components in EcoCare feed reduce manure solids and viscosity, resulting in improved physical uniformity of the manure, making it easier to agitate in manure storage pits and manipulate through manure-handling equipment. Internal research trials have indicated a reduction of 14% in solids and 22% in viscosity over a 45-d collection period; these physical changes may have positive implications for manure pit pump-out and facility sanitation. EcoCare feed also has the potential to reduce ammonia emissions. This is achieved primarily by inclusion of crystalline AA, specific Bacillus bacteria, and saponin-derived compounds. Emissions measured in a manure-pit simulation trial performed at LongView Animal Nutrition Center (Gray Summit, MO) demonstrated that pigs consuming EcoCare feed excreted manure in which ammonia volatilization was reduced by 18% over a 45-d period when compared with control pigs. Over time, EcoCare feed may result in reduced production of ammonia by up to 40% in commercial situations. Nutrient manipulation of feed can help greatly in the reduction of nutrient waste. Reducing N loss can be achieved by incorporating supplemental crystalline AA in the diet and by using specific feed additives that can reduce the volatilization of N-containing ammonia from manure pits. The excretion of P can be reduced by using phytase in the diet, thereby improving P digestibility and reducing the requirement for dietary inorganic P. These types of manipulations can be achieved without limiting swine growth performance. In fact, EcoCare feed has been shown to improve the feed conversion ratio by up to 4% over other standard feeds in field conditions.

The present invention includes a liquid sweetener made from a lactose containing liquid that can be used to coat animal feed to increase palatability. It also includes methods of making the liquid sweetener and making animal feed with increased palatability. The methods include hydrolyzing whey or whey derivatives and adding amino acids to promote a Maillard reaction to synthesize the sweetener.

Rumen performance and ruminant growth in growing ruminants is studied through rumen morphological studies and growing ruminant developmental studies. Based on the studies, a feed composition containing an effective amount of milk replacer, supplemental feed or both is administered to the ruminant over a growing period to optimize rumen growth. A method of formulating a feed formulation for a ruminant involves studying at least rumen morphology of one ruminant ingesting a diet with an amount of milk replacer, supplemental feed or both, and formulating the feed ration for another ruminant based on the study. A feed composition formulated based on rumen morphological studies includes an effective amount of nutrients to optimize rumen growth in the growing ruminants characterized by one or more of optimized rumen size, rumen papillae density, rumen papillae surface area, rumen papillae histology in the ruminant by twenty-four weeks of age.

The present invention includes extruded livestock feed particles comprising a high level of fat and methods of making these animal feed particles. The particles are palatable and digestible by the livestock animals and lead to an enhanced energy intake by the animals. The particles are also flowable. The method includes the use of a vacuum coater to incorporate the fat into extruded animal feed particles. The present invention also includes methods of feeding dairy cows.

A semi-solid animal feed block is provided to an animal as a feed supplement or as a complete feed. The feed block is formed of a liquid binder containing denatured wheat flour protein and sugar, and a nutrient mixture of at least one animal feed component. The denatured protein and the sugar bind the nutrient mixture to form the semi-solid animal feed block as a single mass. The nutrients may be formulated to promote digestive tract development of a recently weaned livestock animal, such as a piglet.

The present invention relates to treatment of milk and milk products such as waste-milk with an enhanced lactoperoxidase system. The enhanced lactoperoxidase system is activated by the addition of a hydrogen peroxide source and an oxidizable agent, such as a halide to the milk to inactivate the bacterial pathogens. The enhanced lactoperoxidase system may be used alone or in conjunction with pasteurization to reduce or eliminate the bacterial load in milk products.

The present invention relates to feed compositions that can modify the feeding behavior of animals. Supplements can be added to no or low roughage rations that improve the performance of animals. In particular, the addition of calcium chloride to a low or no roughage ration can increase the number of feedings but decrease the amount of feeding per meal. This can result in promoting enhances feed conversion and better cost of feed to weight gain.
