Abstract

Insect meal is an unconventional feedstuff and is expected to be an alternative protein source in broiler diet in the future, as an impact of high price and a limited supply of a fish meal. The objective of this paper is to describe the potency of insects as a feedstuff in broiler diet. Some types of insects, i.e., bees, flies, crickets, grasshoppers, termites, ants, and cockroaches have the potential to be a feedstuff protein source. Several studies reported that insect has high protein content (10.3-76.2%). The use of insects as feedstuffs in broiler diet is constrained by several limiting factors, i.e. the presence of chitin, high crude fat content, and the presence of contaminants. Processing insects before being used as feedstuffs is necessary. Separation of chitin and crude fat content are highly recommended before using insect as protein source feedstuff in broiler diet. The use of insects in a broiler diet ranges from 4 to 29.65% depending on the type of insect, life phase of insect and the type of processing. Research and development to increase insect utilization in broiler diet are still needed.

Abstract

Lysozyme is one of the constituent proteins of chicken egg white that plays an important role in a protection system during the embryo growing process. Lysozyme protection systems can be applied in food and for health. This paper aims to describe the role of egg white lysozyme which has the antibacterial activity to improve food safety and health. Mechanism and activity of lysozyme protection can be explored by understanding the structure of proteins, type of amino acids, and the sequence of amino acids. The mechanism of lysozyme antibacterial activity against Gram positive bacteria occurs through its ability to breakdown the peptidoglycan glycosidic bonds in the bacterial cell wall membrane. The antibacterial activity of lysozyme can be increased when its normal lysozyme form was denatured/hydrolyzed through modifying the lysozyme structure by heat and enzymatic treatment. Heat treatment will reveal the active site of lysozyme after denaturation, leading to the destruction of the bacterial cell wall membrane. Enzymatic treatment through hydrolysis process of hydrolysis by protease enzymes will generate antibacterial peptides, which have the ability to inhibit the growth of Gram positive bacteria and Gram negative bacteria. Antibacterial lysozyme peptides and heat treated lysozyme are dominated by hydrophobic amino acids and positively charged to facilitate interaction between lysozyme and lipopolysaccharide which coats peptidoglycan. Antibacterial lysozyme peptide can be used as an antibiotic and a safe natural preservative compared to synthetic material and can reduce the risk of destructive bacteria and pathogenic bacteria. Lysozyme peptide is potential to protect human health since it has also other activities such as inhibition of angiotensin-converting enzyme, antihypertensive, antitumor, antioxidant, and antiviral agents.

Abstract

Biomass by-products or plant residues from the plantation system would play a crucial role in animal production since the utilization of forages from the underneath tree crops would be less or minimal when the palm oil crop mature. By-products generated from the palm oil system vary, but in relation to the animal production they could be generally categorized into the fibrous by-products and the non-fibrous (concentrate) by-products. Palm oil mill effluent (POME) and palm kernel cake (PKC) are concentrate by-products produced during the processing of palm oil extraction which have great potency to support sheep and goat production, although limiting factors such as contamination of shell and high copper level in PKC need to be considered in their utilization as feed. The fibrous palm oil by-products include oil palm fronds (OPF) and oil palm trunk (OPT) generated from the palm crop trees and oil palm empty fruit bunch (OPEFB) and palm pressed fiber (PPF) generated from processing of fresh fruits to yield crude oil. These fibrous by-products cannot meet the metabolisable energy required for high growth rate and for lactation of sheep and goats due to low DM digestibility, low crude protein content, low fermentable carbohydrate and low level of intake. Limited inclusion level in ration should be applied for those by-products to yield an acceptable production level of sheep and goats. Pretreatments (physical, chemical, and biological) gave some improvement in their nutritional qualities, however additional cost of pretreatments need to be considered. In the future, there would be a great challenge for the utilization of those fibrous by-products as animal feed since bioconversion of lignocellulosic materials to products such as chemicals (bioethanol, sugar, and bioplastic), fuels, and organic fertilizers are receiving greater interest. Some comparative advantages of these natural wastes are their relatively low cost, renewable and widespread in nature for used in an industrial operation.

Abstract

Indonesia has a number of cattle breeds that have certain advantages as meat-producing cattle with high adaptability to the local environment. Local beef cattle breeding has now been carried out by the government through technical implementation unit. Efforts to build local cattle breeding still need to be improved to be able to meet sustainably the demands of local cattle breeding stocks for the farmers. However, beef cattle breeding business is less attractive to investors because it is economically less profitable and requires a long maintenance time compared to the fattening business. This paper aims to provide an overview of thoughts in an effort to improve the performance of local beef cattle breeding in Indonesia. In supporting the local cattle breeding program, the role of central and regional governments still has to be dominant mainly in the establishing of breeding centers as the core and policies related to the operationalization of activities involving farmers and other stakeholders.

Abstract

African horse sickness (AHS) is one of the important arbovirus diseases in horse. The disease is fatal and should be transmitted by vector. This disease is potential to spread rapidly and has impacts in public health and socio-economic, especially in the international trade of horses and its products. The paper describes AHS, some factors that influence the disease, how to control the disease and its current situation in Indonesia. African horse sickness has been declared as notifiable disease in OIE list, therefore, the disease becomes strategic in the country that has high horse population. Climate changes affect vector population and spreading of the disease. In order to anticipate the entering of AHS infection in Indonesia, the government needs to facilitate the research on horse diseases including the safe laboratory facilities to handle exotic diseases and provide diagnostic tool for early detection.
