I. INTRODUCTIONBroiler breeders require adequate levels of nutrients to reach their genetic potential in terms of productive and reproductive performance, and to transfer essential nutrients from eggs to embryo for the development of chicks (Rajashree et al., 2014).It is known that oxidative stress impairs a breeder’s performance (particularly related to aging) and embryo development. This s ...

I. INTRODUCTIONMetabolizable energy (ME), digestible amino acids (dAA) and available phosphorus (avP) are the largest and most expensive components in broiler diets, considerable fractions of which still pass through the digestive tract undigested and are lost via excretion (Ravindran et al., 2013), hence, emphasizing the need for higher nutrient usage efficiency than current practice. Ability of ...

The induction of oxidative stress by heat exposure, as well as the relationship between selenium (Se), selenoproteins and oxidative stress, is well described in the scientific literature (Habibian et al.,2015). Zhao et al. (2017) showed that hydroxy-selenomethionine (OH-SeMet) differently affected the expression of the selenogenome as compared to sodium selenite (SS). Hence, it was hypothesised th ...

ABSTRACTThe primary objectives of this research were to measure total and phytic phosphorus (P) in a range of ingredients and to establish prediction model using near infrared spectroscopy (NIRS). A total of 227 ingredient samples was collected worldwide during one year and most of the sampled ingredients were cereals, cereal byproducts, oilseeds and oilseed meals. All of the s ...

ABSTRACTNutritive values of major ingredients vary considerably not only among different feedstuff but also the same ingredients of different batches. Rapid screening nutritive value has been a great challenge in the feed industry. This study assessed 4 soybean meal (SBM) samples using both NIRS technique and broiler experiments. In broiler Test 1, 4 SBM samples were assigned the&nb ...
