The proven complex of technologies for embryo transplantation on an industrial scale will provide a 3-5-fold acceleration of reproduction of highly productive cows. As a result of scientific research, biotechnological methods of accelerated reproduction of dairy cattle have been substantiated and introduced … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 14 Oct 2024 · 4,298 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAbsorption of Food Along the Guts of Parachanna obscura and Clarias gariepinusEunice O. Idowu, Adewumi A. Adejoke, Josephine B. Edward et al.The knowledge of feeding habit and absorption of food in the gut of fish is important for fish farmers to boost their production and meet the ever increasing demand for man consumption. The carbohydrate, protein and lipid contents of the food ingested and their absorption in the intestine of Parachanna obscura and Clarias gareipinus inhabiting Ogbese River in Ekiti State … …American Journal of Environmental Sciences, Vol. 16, Issue 1 · 26 Feb 2020 · 7,325 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMicroalgae Schizochytrium sp. in Feed for Piau Leporinus fridericiAline D.S. Prates, Marianne Schorer, Guilherme S. Moura et al.The objective of the study was to evaluate the growth of piau (Leporinus friderici) juveniles fed with diet supplemented with different levels of Schizochytrium sp. One hundred and forty juveniles of L. friderici were stocked in 20 aquariums (35 L) at the density of 0.2 fish L-1, weighing and measuring 11.80±1.08 g and 9.68±0.31 cm, respectively.

The purpose of this study is to examine the development of soil and water quality as well as the behavior of soil and water quality parameters, which act as a limiting factor and determinant of the quality of natural food and fish life … …American Journal of Environmental Sciences, Vol. 12, Issue 1 · 2 Mar 2016 · 7,202 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Dietary Inositol on Growth, Feed Utilization and Blood Biochemical Parameters for Juvenile Barramundi (Lates calcarifer Bloch)Shi-Qiang Diao, Zhong Huang, Shui-Sheng Chen et al.Problem statement: The utilization of inositol was detected for growth performance and erum biochemical parameters of juvenile barramundi (Lates calcarifer). Approach: A 56 day feeding trial was conducted to evaluate the effect of inositol on growth, feed utilization and serum biochemical parameters for juvenile barramundi Lates calcarifer (initial size 5.51±0.07g). Six experimental fish meal-based isonitrogenous (42% crude protein) and isolipidic … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,322 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Supplemental Lysine and Methionine on Growth Performance and Body Composition for Grass Carp (Ctenopharyngodon idella)Hui Jun Yang, Yong Jian Liu, Li Xia Tian et al.Problem statement: The utilization of crystalline amino acids was detected for growth performance and body composition of juvenile grass carp (Ctenopharyngodon idella). Approach: L-Lysine sulphate and Methionine Hydroxy Analog-Ca (MHA-Ca) were selected for determination. Two diets were formulated with or without amino acids supplementation. Each diet was assigned to 10 tanks in a completely randomized design for 8 weeks. Results: … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 8,657 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Feeding Strategy and Carbohydrate Source on Carbohydrate Utilization by Grass Carp (Ctenopharyngodon idella)L.X. Tian, Y.J. Liu, S.S.O. Hung et al.Problem statement: Feeding strategy is the important factor in aquaculture. Feeding strategy not only could affect the growth performance of grass carp and feed efficiency, but also could affect the quality and environment of water resource. We have proved that glucose was more suitable than starch as the carbohydrate source for grass carp under the restricted feeding frequency. While different … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 8,991 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPotential, Implications and Solutions Regarding the Use of Rendered Animal Fats in AquafeedsJesse T. Trushenski, Rebecca T. LochmannProblem statement: In the past, aquafeeds were comprised largely of fish meal and fish oil derived from marine reduction fisheries. In addition to being highly palatable and readily digested by cultured fishes, these feedstuffs were historically inexpensive sources of protein, energy and essential nutrients. However, increasing cost and concerns over safety and sustainability have greatly incentivized the transition from fish … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 13,998 accessesView PDF Cite
