The objective of this study was to evaluate the efficacy of EK extender alone or incorporation with CoenzymeQ10 (CoQ10) and/or soyphosphatidylcholine (SPC) in poultry semen and their effects on seminal traits during temporal storage at 4⁰C for different time intervals (12 h, 24 h, and 36 h). Heterospermic pooled semen samples diluted (1:4) with EK, EK + SPC, EK+ CoQ10 and EK + SPC + CoQ10 extenders separately, preserved and different spermiogram were assessed. Various seminal traits within the same extender differ significantly (p<0.05) among different groups and with different time intervals of storage. CoQ10 and SPC in the EK extender exhibited favorable synergistic effect on sperm quality and were able to protect the male gametes against cold-stress up to 36h at 4⁰C. In this study, we concluded that incorporation of SPC and CoQ10 together in EK extender possess novel potentiality to maintain seminal quality during liquid storage of poultry semen at 4⁰C and for their safe transportation and further use for Artificial Reproductive technologies (ARTs).

Five studies were performed to determine factors affecting progesterone concentration in skim milk. Results of the first study indicated that progesterone concentration was higher in skim milk of samples kept 16 hours in an ice bath (0 C) than of those left at room temperature (21 C). In the second study, this temperature effect was found to be reversible, with skim milk progesterone concentration increasing when whole milk samples were cooled prior to centrifugation. In the third study, [3H]-labeled progesterone was used to determine the relationship between fat content of foremilk (the first milk obtained from the teats), midmilk (milk obtained through milking), and strippings (milk obtained immediately after milking machines have been removed) samples and temperature (4 C and 21 C) on the percentage of progesterone in the skim milk fraction. The relationship between percentage of butterfat and percentage of progesterone in skim milk was linear when the log of these variables was used for calculations. In the fourth study, assayable progesterone in the skim milk fraction of foremilk, midmilk, and strippings was affected by temperature. In the fifth study, a multiple-regression procedure was used to determine the amount of variation in percentage of radioactive progesterone in the skim milk fraction. Independent variables (whole milk butterfat and temperature of incubation [1, 3, 13, 22, 37, and 50 C]) and the natural log of each variable, were entered into a stepwise multiple-regression analysis. The log of the temperature and percentage of butterfat of whole milk at the time of centrifugation accounted for 89.2% (r2 = 0.892) of the variation in the log of the progesterone concentration in the skim milk fractions. The equation describing this relationship was: log percentage of progesterone in the skim milk fraction = 4.046 - 0.144 X (log of temperature of whole milk sample) - 0.688 X (log percentage of butterfat in whole milk sample). The loss of progesterone from skim milk fractions of warm whole milk samples is possibly a physical phenomenon dependent on the temperature of the sample and its percentage of butterfat. A nomograph was created to allow others to use these variables in making adjustments in progesterone concentrations.

Biogas plant is an anaerobic digester that produces biogas fromorganic materials. The general purpose of implementing biogas plant in an animal farm is to obtain biogas from animal manure and the effluent of biogas digester after fermentation process can be used as organic fertiliser. There are 15 biogas plants based on livestock waste that have been developed throughout Malaysia until 2018. Two more biogas plants are planned to be built in Segamat and Keningau. All biogas plants built were originally aimed for domestic use which is as source of energyused for cooking and incinerator as well as to generate electricity for farm use. Out of 15 biogas plants, 7 plants were built on cattle farms, 4 plants on pig farms, 3 plantson poultry farms and only 1 plant on buffalo farm. Total construction cost for each biogas plant is between MYR4,500 to MYR30 million. Based on the survey conducted, it revealed that only 40% of the plants are still functional. However, 60% were dormant or nonfunctional due to poor maintenance, design errors, lack of technical knowledge to run the system consistently, improper planning and monitoring or insufficient livestock waste to continuously producing biogas.

nematodes of ruminants, large scale technique for recovery of worms migrating from gastro-intestinal ingesta gelled in agar, significantly more male than female worms failed to migrate, L4 stages generally migrated more efficiently than did adult worms, some genera migrated more efficiently than others, applications for use in quantitative worm recovery such as in anthelmintic testing

The research in RUP Scientific and Practical Center of Animal Breeding of National Academy of Sciences on such parameters as consumption of forages, processes of rumen digestion, morphological and biochemical structure of blood has shown that usage of wet grain preserved with Kormoplus for young cattle fattening has a positive effect on physiological condition and digestibility of nutrients and promotes nitrogen usage by animals that increases at 7,0 and 1,6%

Usage of preservatives Kormoplus 1 and 2 lets us produce the silage of a highest quality and raise dry substance integrity at 8,7%, protein - at 12-9,4%. The researches determined that cereal silage, prepared with supplement Kormoplus 1 and 2, lets us raise digestibility of dry substance at 5,5% and 3,7%, organic substance - at t 5,5 and 4,0%, fiber- at 16,5 and 15,0% and raise nitrogen sediment at 17,4 and 20,8%. These forages didn't have any negative influence at health and biochemical performance of cow blood

In the conditions of the Republic of Belarus there was studied the efficiency of application of forage chemical preservatives Kormoplyus-1, Kormoplyus-2, and Kormoplyus-3 for grass fodder conservation. The analyzed preservatives contained acetous acid, urotropine and sodium acetate (only in Kormoplus-2). In course of the study there were established experimental batches with the studied sreservative; there was determined a chemical composition of prepared forages; in physiological and scientifical and economic experiment there was analyzed the feeding efficiency of cereal ensilage. Research results showed that application of preservatives Kormoplyus-1 and Kormoplyus-2 2 for preparation of cereal ensilage made it possible to receive a high quality ensilage and to increase the dry matter safety on 4,2-8,7% and protein on 12-9,4% on comparison with storage without preservatives. Also, it made it possible to increase the digestibility of dry matter in cattle diets respectively on 5.5% and3.7%; organic substance - on 5.5% and 4.0%; fibre - on 16,5% and 15,0%, and also to increase nitrogen deposition on 17,4 and 20,8%. Feeding with forages preserved with Kormoplyus-1 and 2 did not render negative influence on a health state and biochemical indices of animal blood.
