Livestock offers substantial opportunities for food security and sustainable development with appropriate adaptation to climate change. Nowadays, change is among the critical problems facing less privileged rural people directly depending on livestock survive. This paper aimed analyse existing literature identify knowledge gaps about impacts response strategies in production of South Africa. Th...

Phytic acid (InsP(6)) is considered to be the major source of phosphorus and inositol phosphates in most cereal grains. However, InsP(6) is not utilized efficiently by monogastric animals due to lack of phytase enzyme. Furthermore, due to its ability to chelate mineral cations, phytic acid is considered to be an antinutrient that renders these minerals unavailable for absorption. In view of the...

This study examined the feasibility of using the promoter of the pig parotid secretory protein (PSP) gene for expression of the phytase transgene in mouse models. The pig parotid secretory protein gene is specifically expressed at high levels in the salivary glands. The 10-kb upstream promoter region of the gene necessary for tissue-specific expression has been identified. We have constructed p...

Phosphorus of plant-based feedstuffs for monogastric animals is mainly in the form of phytic P, which has a very low bioavailability. The nondigested phytic P may contribute to P pollution. Furthermore, phytic acid may reduce digestibility of other minerals and protein. This study evaluated effects of the microbial 6-phytase RONOZYME HiPhos on apparent ileal digestibility of P, phytic acid, Ca,...

Mungbean has claimed its rich source of protein and premium quality of starch; however the disadvantage of antinutritional factor phytic acid in monogastric animals is needed to be decreased. Understanding both upand down-stream of phytic acid biosynthetic pathway will be a great benefit for controlling the appropriate level phytic acid in legumes. Cloning of D-myo-inositol 3-phosphate synthase...

As a monogastric herbivore, the rabbit presents a unique feeding behaviour compared to other domestic animals, since he belongs to the Lagomorpha order (Leporidae family: rabbits and hares, Grassé and Dekeuser, 1955), and consequently possess a main specificity that is the caecotrophy. For recall (see details in chapter 1), the caecotrophy is a complete behaviour involving an excretion and an i...

Rates of oxalate degradation by mixed bacterial populations in cecal contents from wild rats ranged from 2.5 to 20.6 mumol/g (dry weight) per h. The oxalate-degrading activity in cecal contents from three strains of laboratory rats (Long-Evans, Wistar, and Sprague-Dawley) from four commercial breeders was generally lower, ranging from 1.8 to 3.5 mumol/g (dry weight) of cecal contents per h. Thi...

Tannase (EC 3.1.1.20) is an enzyme that hydrolyzes the ester and depside bonds of tannic acid to gallic acid and glucose. In the production of foods and beverages, it contributes to the removal of the undesirable effects of tannins. The aim of this study is to investigate the potential of endophytic fungi isolated from jamun (Syzygium cumini (L.) Skeels) leaves, and identified as Pestalotiopsis...

Vitamin A (retinol) is an essential micronutrient with a crucial role in the immune system of non-ruminant animals, such as swine and poultry. It includes three chemical compounds distinct properties functions body: retinol, retinal, retinoic acid. In monogastric feed, vitamin primarily present form retinyl esters. The metabolism dietary esters involves their conversion to which then transporte...
