Insect base-protein: A new opportunity in animal nutrition
Published May 20, 2020
129-138

The consumption of insect protein, as well as its use in animal feeding, has become a trend. This trend is particularly receiving a lot of attention in animal nutrition because the current protein source of the highest quality in animal feeding which is fishmeal is unsustainable, expensive and its demand is higher than supply. Insect protei...n can be of great potential in combating world hunger as the world population continues to increase. The potential of insect protein is wide-ranging, it could improve the economics of feed production, lead to cleaner production due to its low environmental footprint.

This review focuses on the need, (nutritional and environmental) advantages of insect protein in feed production, as well as previous research findings.

The unanimous conclusion of the reviewed papers is that insect protein has a great potential in feed production in terms of nutritional value, environmental implication, sustainability as well as economic implication.

However, there is a need for the intensification of research on this alternative protein source in Europe, especially in aquaculture due to the approval of 7 insect species in aquafeeds by the European Union. Another reason for the intensification is that there is still much to be done as a result of past research which shows that growth effects vary based on species and inclusion level.

Some strategic aspects of animal protein production
Published September 5, 2018
11-19

The access to food shaped human societies and dietary models throughout the history of mankind. Animal protein consumption became a part of human culture. Data are presented showing the relationship of daily calorie and animal protein consumption as affected by capita GDP changes. Examples are presented how genetic improvement of animal and fod...der plants influenced the resource efficiency and the overall environmental footprint per unit product. The two examples presented are: the dairy industry of the USA the 1944 and 2007 situation, and the Hungarian broiler chicken sector considering data relevant to 1930, 1960 and 2010. In both cases, dramatic improvements in resource efficiency could be demonstrated. The agricultural area required to animal feed production was reduced by more than 80% in both cases per unit product. Future possibilities are briefly discussed, referring to the still unutilized land reserves of the Globe, the new evolving technologies in progress inclusive the CASPR/Cas 9 genetic editing methods.

Some Variable Traits of Broiler Genotypes
Published September 8, 2020
25-30

One the most effective ways to satisfy the requirements of mankind for food of animal origin is the fattening of chicken. Healthy and cheap meat with low fat and high protein content can be produced rapidly and in large quantities by broilers with low feed consumption. This paper presents the production results and carcass traits of three genot...ypes (Ross 308, Cobb 500, Ross broiler parent) females and males at the age of 42 days.
In both sexes, we found that the average body weight of the Ross parents genotype was higher (females: 2643 g; males: 3089 g) than the
average body weight of the other two hybrids – significant difference was found only between pullets. However, the smallest difference in the
average body weight between the two sexes (446 g) was found in this genotype. In both sexes, the lowest average weight was detectable in
the case of the Cobb 500 hybrids (females: 2443 g; males: 3052 g).The feed consumption ability of the females were worse – in all but one
case (Ross pullet) – than that of the males. For one kg of weight gain - in the order of genotypes – 1.79kg, 2.08kg and 2.08 kg of feed was
used. The same values for the males were as follows: 1.81kg, 1.80kg and 1.89 kg, respectively.
Carcass traits were examined and it was found that the average grillfertig weight, the weight of whole thigh meat and thigh meat of the
Ross parents’ genotype was higher than the average weight of the other two hybrids. Significant difference was found only in grillfertig- and
whole thigh meat weight. Pullets of the Ross parents’ paternal line had worse results in the average weight of breast meat with bone and
breast meat fillet than the other two genotypes. In the case of cocks was detectable the inverse of this: the average weight of breast meat with
bone was the highest in the cocks of the Ross parents’ maternal line.

Some basic problems concerning world animal production at the beginning of the XXI century
Published November 13, 2012
77-80

The author summarizes the main new challenges facing animal agriculture: growing GDP in many countries increasing animal protein demand, bioenergy industry as a new player using potential food or feedstuffs, increasing demand, Growing water and land scarcity, weaking the position of plant agriculture, feed production. Forecasts are summarized r...egarding the magnitude of meat consumption increases, and the possible plant biomass quantities required additionally in the next 20 years to cover the needs of food, feed and biofuel on a global scale.
Efficiencies of various animal production sectors, poultry, pork, beef, mutton meat, milk and eggs and their environmental footprints are compared, summarizing the most important research  results concerning UK, USA, OECD evaluations. Intensive systems using highly productive plant and animal population will play an even more important role in the future especially in poultry, pig, milk and aquaculture production system being efficient users of resources (feed, water, land) and the environmental foot print is smaller per unit product.
