Introduction The optimal concentration of nutrients required by growing pigs generally decreases over the growing-finishing period with a phase feeding program used as an attempt to meet the needs of the pigs over the changing requirements. Thus, in commercial production, phase feeding is thought to improve economics and reduce nitrogen excretion by more closely meeting the pig’s nutrient requirements compared to feeding fewer phases. However, in practice, it is...
1. Introduction At times, sorghum provides, either partially or entirely, the feed grain base in Australian pig and poultry diets but it has been associated with sub-optimal or inconsistent growth performance in broiler chickens (Selle et al., 2010a; Liu et al., 2015a). A beneficial characteristic for including sorghum in broiler diets is as a source of energy, which is mainly derived from starch. However, energy...
Soybean hulls are a by-product of soybean oil processing, accounting for 10% of the total volume and 8% of the total weight of soybean. Soybean hulls are mainly the outer coating material of soybean, the color is beige or light yellow, the main components are cell wall and plant fiber. Molasses bean skin is a special product which is made by spraying concentrated soybean oligosaccharides onto soybean hulls and drying with unique technology. Molasses bean skin contains 30% of soybean...
Introduction The transition period into lactation remains one of the most challenging and important phases of the production cycle in a dairy cow. It is a transient period around calving characterised by drastic changes in the hormonal status, 2 to 5-fold (Bradford, 2020) increases in nutrient demand and apportioning of 85% of body glucose to the mammary gland. Simultaneously, the requirement for specific fatty acids escalates by more than four times (Bell, 1995; McFadden and...
Interesting facts The presence of fat in the diet inhibits the synthesis of fat from carbohydrates. The final composition of body fat is a pondered average among the fat produced endogenously from glucose, the quantity and composition of the fatty acids in the diet and the fat resulting from catabolism through b-oxidation (Ajuyah et al., 1991; Ferreira, 1999, Sanz et al., 2000b). Female broiler chickens tend to deposit more fat than male broiler chickens....
Nasser Odetallah, Executive Manager for Global Technical Services at Novus, speaks to us about raw materials quality during Novus 25th Anniversary Celebration held in their HQ in Saint Charles, Missouri....
Introduction Current broiler growth rate is partly the result of an intense genetic selection; 1 therefore, feeding is important to achieve the maximum productive expression. Success attained until now in this practice has been due to better knowledge of the functions that different nutriments carry out, which in turn allows higher precision when establishing nutrimental needs. 2 To be able to feed...
Michaela Braun (Kansas State University) presented her results on this research regarding the use of added enzymes in broilers, during IPPE 2020 in Atlanta, USA....
Leo Obaldo (Hawaii Department of Agriculture) discussed existing management practices and alternative sources of feed like Black Soldier Fly, during 2019 NIAA Annual Conference: Animal Agriculture - Innovation, Technology and Consumer Engagement in Des Moines, Iowa, USA....
1. Introduction Pelleting is the most used thermal processing method in poultry industry. The aim of pelleting processing is to agglomerate ingredients particles by mechanical action, in combination with moisture, pressure and temperature. Broilers fed pelleted diets present greater feed intake, better feed conversion ratio and greater weight gain [1-3]. The positive effect of pelleting on broiler performance is partly due to improved nutrients digestibility [4], increased feed...
Due to the COVID-19, we have made the unfortunate decision to cancel this years symposium. We hope that everyone stays healthy during this time of crisis. Please mark your calendars for 2021 as this will mark our 25th Anniversary symposium and we will be coming back to where it started in bourbon country, Louisville, Kentucky. The...
Yangchun Cao (Northwest A&F University) shared his research and talked about the effect of digestive processes and liver metabolism of lipogenic precursors on milk fat synthesis, during the 8th Symposium on Gut Health in Production of Food Animals in St. Louis, USA....
