The aim of this study was to evaluate the effects of different frequency feeding and aging of leaves on increasing weight of silkworm instar IV-V and cocoon production. The research was conducted in Cultivation Center of Silkworm Candiroto, Temanggung. The research design was Factorial Design with three level of age from the leaves (the third – fourth leaves from tip of leaf; fifth-sixth leaves from tip of leaf; sevent-eight leaves from tip of a leaf, and three level of feeding frequency 3, 4, 5 times/day). The parameter observed were average daily gain (ADG), weight of cocoon, and weight of empty cocoon. The data gained were analyzed by analysis of variance and to find out the difference caused on the treatments, Duncan Multiple Range Test was used. It is concluded that the different frequency of feeding and age of leaves is significant (P less than 0.05) in ADG of silkworm and weight of empty cocoon. The seventh- eight leaf from tip of a leaf, and frequency of feeding five times/day resulting ADG and empty cocoon of the best.

The studies were carried out on three groups of superreplacement heifers of the Simmental breed, which were impregnated at the body weight of 360 kg. In the first group there were 32 unimpregnated heifers, in the second – 28 heifers, in the third – 30 heifers. The heifers of the first group after growing at the age of 18 months were taken for meat. 56 heifers gave the crop. The heifers were transferred for reproduction, and the bull-calves were put on cultivation and further fattening. To obtain well-fed animals, special diets were made so that the average daily gain was at least 650-700 g. After calving, the cows of the second group were taken for meat, and the cows of the third group were put on a 3-month fattening, and then taken for meat. The pre-slaughter weight of animals of the first group was 52 kg lower than that of animals of the second group and 104.7 kg lower than that of the third group. The difference was statistically significant at P>0.999. The interior fat mass was higher in the carcasses of cows of the second group by 1.1 and 3.2 kg compared to the animals of the third and first groups. The carcass yield was almost at the same level slightly ahead of the animals of the first group. Their slaughter yield was 60.1%, in other groups – 58.8-59.6%. The meatiness ratio was slightly higher in animals of the first group. The carcass weight of the first-calf heifers of the third group was 27.4 kg higher than that of the second group. Compared to the first group, this figure is higher by 52.6 kg. Specific carcass meat weight of the animals of the third group was 82.75%, which is higher than in the second and first groups by 0.41-0.85%, respectively. Heavy cowbanes weighing 32.6 and 40.4 kg were obtained from the animals. The skin of animals of the third group was 3.5-21.6 dm2 larger in area than of the animals of the second and first groups. Feeder bull-calves (n=27) had a removable mass of 532 kg. Heavy (282.3 kg) carcasses of good morphological composition were obtained from them. The sales revenue from first-calf heifers (second group) was higher than fattened heifers by 10.4%, and in comparison with fattened animals after calving (third group) it was lower by 9.4%. From the sale of one cow with a crop, 2.9 times more profit was received than from the sale of a heifer.

Abstract(An experiment with two groups of East Balkan pigs – castrated males (n=10) and females (n=10), was carried out to study the growth performance and fattening abilities of the animals from the weaning until slaughter. The pigs were included in the trial at 60 day age. The average live weight of the castrated males was 8. 65±1.08 kg and for the females, 8.5±0.62 kg.The pigs were reared using traditional technology, grazing on natural pastures in the Strandzha mountain, Bulgaria. In autumn, acorns were naturally present in their diet. According to the category, the animals additionally received ground organic feed (50% barley and 50% wheat). The trial lasted 304 days (from February to November, 2019). During this period the final live weight of the male castrated pigs reached 88.00 kg while that of the females was 84.4 kg. The difference, however, was not significant. Furthermore, no significant differences in the growth performance characteristics that could be attributed to the sex of the animals were observed. The average daily gain of both sexes tended to be lower in summer and higher in autumn. The feed conversion ratio was higher in summer. The animals showed high average daily weight gain at pasture when their live weight was over 50 kg.

Visfatin encoded by the <I>NAMPT</I> gene <I>(nicotinamide phosphoribosyltransferase,</I> formerly also known as <I>PBEF – pre-B cell colony-enhancing factor</I>) is suggested to play a role in lipid metabolism and pathophysiology of diabetes mellitus type 2. A new microsatellite <I>SCZ004</I> was detected within intron 9 of the <I>NAMPT</I> gene. In Czech Large White (<I>n</I> = 95) frequencies of alleles <I>282, 286, 287, 299</I>, and <I>304</I> were 0.02, 0.39, 0.07, 0.04, and 0.48, respectively. Allele <I>286</I> was predominant also in Landrace (<I>n</I> = 11) and Black Pied Prestice (<I>n</I> = 11) breeds. Association analysis was carried out between previously reported SNP AM999341:g.669T>C in intron 9 of the <I>NAMPT</I> gene and backfat thickness, average daily gain and lean meat content in Czech Large White (<I>n</I> = 215), Black Pied Prestice (<I>n</I> = 96) and Landrace (<I>n</I> = 105). The <I>CC</I> genotype was associated with higher backfat thickness (<I ≤ 0.01) in Black Pied Prestice, however in Czech Large White <I>CC</I> was associated with lower backfat thickness when compared to <I>TT</I> and <I>CT</I> genotypes (<I ≤ 0.05). In Czech Large White, <I>CC</I> genotype was associated with higher lean meat content when compared to <I>CT</I> (not significant) and <I>TT</I> genotype (<I ≤ 0.05) while in Landrace <I>CC</I> had the lowest lean meat content when compared to <I>CT</I> and <I>TT</I> genotypes but only the difference between <I>CC</I> and <I>CT</I>T was statistically significant (<I ≤ 0.05). In Black Pied Prestice no association with lean meat content was found. Average daily gain was not associated with the SNP in any breed.

Silkworm Bombyx Mori

Although the ecdysteroid of the silkworm had been studied for decades, the proteome of the prothoracic gland, the primary source of ecdysteroid hormones, has not been studied previously. In the present paper, we utilized a proteomic approach to investigate the fifth instar prothoracic gland during the growth and development of the silkworm, Bombyx mori L. The two-dimensional electrophoresis results showed that the majority of proteins were acidic proteins, especially concentrated in the area of 25–65 kDa, with pI values of between 4 and 7, and the difference was not distinct. When compared with Qiufeng (Japanese strain), the interspecific distinction was larger than the intraspecific distinction, and 19 particular spots, excized from the third, fifth and ninth days of p50 (Chinese strain) and Qiufeng were subjected to MALDI-TOF–MS (matrix-assisted laser-desorption ionization–time-of-flight MS) analysis. We sorted them into seven catagories: energetics and/or metabolism, storage proteins, protection, lipid metabolism, signal transduction, cell function and unknown function proteins. Of these proteins, arginine methyltransferase is discussed as playing an important role in regulating the activation of ecdysteroidogenesis via transcription or translation.

ABSTRACT: Three experiments were conducted to determine the nutritional composition of tilapia filleting waste meal (TFWM) for pigs in the initial phase. In the first experiment, the chemical composition and the values of digestible and metabolizable energy of TFWM were determined using 10 pigs (15.10 ± 0.74 kg), distributed in cages for metabolic research (2 treatments X 5 replicates). The TFWM replaced 20% of the reference diet based on corn and soybean meal. In the second experiment, the ileal digestibility coefficients of amino acids present in TFWM were determined, using chromic oxide as a marker, through the method of sacrifice, using 10 pigs (15.00 ± 0.27 kg), distributed in cages for metabolic research (2 treatments X 5 replicates). Treatments consisted of a basal diet and one without protein. In the third experiment, the performance of pigs fed diets containing different concentrations of TFWM (0, 5, 10, 15 and 20%) was evaluated. Forty pigs (15.00 ± 0.87 kg), distributed in pairs in nursery pens (5 treatments X 4 replicates) were used. The values of digestible and metabolizable energy corresponded to 3,632 and 3,260 kcal/kg, respectively. Inclusion of up to 10% TFWM in the diet of barrows from 15 to 30 kg did not affect the average daily gain and feed conversion of the animals.

The investigation was carried out in the “Rossiya” LLC in Mozhginsky district of Udmurt Republic. For research three groups of piglets of large white breed at the age of 30 days after weaning from sows were formed according to live weight at birth. The live weight of hogs at birth were determined by their weighing individually. The first group consists of the pigs whit an average live weight at birth 1.25 kg in the amount of 18 heads and the second and third – pigs whit an average live weight under birth 1.45 and 1.71 kg in the amount 14 and 11 heads, respectively. The animals were kept in the group pens. Their feeding was executed fodder of the own production. The conditions of the animals feed and kept in the groups were the same. The aim of the research was to study of a growth, development, and the feed qualities of the hogs in the dependence on theirs of a live weight at birth. The growth and development study of the hogs was carried out by weighing them in 30 days, in 3 months, in 5 months, in 7 months. The study of the feed qualities was carried out taking into account an average daily gain, the expenses of fodder on 1 kg gain and a thickness of the fat over thoracic vertebrae. The obtained experimental data were processed with use of a tabular editor Microsoft Excel – 2010. The reliability of the difference arithmetic means was determined with use of a Student’s -test. Studies have shown that the piglets of the II and III groups surpassed their peers in the I in live weight in 30 days. – by 1.22-2.64 kg, 3 months – 4.56-9.52 kg, 5 months – 11.36-15.17 kg, 7 months – 15.30-15.89 kg (P> 0.999). In terms of average daily gain, fodder costs and fat thickness, the boars of the II and III groups surpassed their peers in the I by: 51.81-91.31 g, 0.29-1.67 fodder. units and 5.78-11.56 mm (P> 0.999), respectively.
