Abstract A system for semi-continuous lamb production was evaluated using Barbados Blackbelly and St. Croix hair sheep ewes under 8-mo accelerated mating. Ewes were managed in a forage-based production system using rotational grazing. Two flocks of ewes (n = 30–35), equally representing the breeds, were bred 4 mo apart. Ewes were synchronized by feeding melengestrol acetate for 10 d, and mated in two single sire groups to like breed sires in November (NOV), March (MAR), and July (JUL) in a 25-d mating period. Pregnancy was recorded by transrectal ultrasound 22 d after breeding. Ewes were supplemented with corn/soybean meal during late gestation (0.75% of BW) and during lactation (1.5% of BW). They lambed on pasture with limited supervision, and lambs were weaned at 2 mo of age. Lambs had access to the supplement provided to ewes. Ewe performance (pregnancy rate, litter size, lamb survival, and birth and weaning weight) was recorded during a 2 yr production cycle, and analyzed for the effect of mating season. Pregnancy rate was not statistically different (P > 0.1) between season, and ranged from 93.9% in NOV, to 85.9 and 86.6% in MAR and JUL. Litter size (lambs born/ewe lambing) was higher (P < 0.05) in NOV (2.09) than MAR (1.68) and JUL (1.82). Lamb survival at birth was reduced (P < 0.001) in JUL (86.5%) compared to NOV (99%) and MAR (100 %), but was not different between seasons for survival to weaning (86 to 90%). Lamb birth weights were higher (P < 0.05) in MAR (3.16 kg) than JUL (2.99 kg), with NOV (3.05 kg) intermediate, while lamb weaning weights were higher (P < 0.001) in NOV (13.6 kg) compared with MAR (11.9 kg) and JUL (11.4 kg) mating. Data suggest that dual flock, accelerated mating of landrace hair sheep ewes can produce lamb cohorts of similar size in 4 mo intervals under a low-input, forage-based production system.

Continuous Preparation

The continuous production of water-soluble low-molecular-weight chitosan (WSLMWC) was successfully achieved with an innovative continuous production system which consisted of ozone generating subsystem, degradation subsystem, and fractionation subsystem. The continuous production of the WSLMWC was performed through three uninterrupted steps: the first, the continuous preparation of the ozone from compressed oxygen, the second, the continuous degradation of chitosan by ozone treatment, and the last, the continuous fractionation of the WSLMWC from the degraded chitosan solution (DCS) by ultrafiltration (UF) membrane. The DCS as the most suitable feed supplied to UF membrane was ascertained. Three different WSLMWC products as useful materials in biomedicine and food were obtained, namely LMWC-3KDa, LMWC-5KDa, and LMWC-10KDa.

Rice–crayfish continuous production system offers high economic and ecology benefits, which developed rapidly in China. To investigate the effects of different mechanical transplanting methods and planting densities on rice yield and quality, Nanjing 2728 was used to determine rice growth performance under mechanically transplanted carpet seedling (MTCS) with equal row spacing (30 cm) at five spacings and mechanically transplanted pot seedling (MTPS) with wide and narrow rows (23 + 33 cm) at five spacings. The results showed that MTPS presented significantly higher rice yields than MTCS as more spikelets per panicle. Rice yields of both mechanical transplanting methods first increased and then reduced with decreasing planting density, and its highest value was obtained at 77.9 × 104 seedlings ha−1. Compared with MTCS at the same stage, rice tiller dynamics of MTPS first increased and then decreased. Additionally, its dry matter accumulation per stem at jointing, heading, and maturity stages, leaf area index, photosynthetic potential, crop growth rate, and net assimilation rate were all significantly higher relative to MTCS. For each mechanical transplanting method, dry matter accumulation per panicle, leaf area index, photosynthetic potential, crop growth rate, and net assimilation rate from the sowing to jointing stages declined with decreasing planting density, while dry matter accumulation per stem and net assimilation rate from the heading to maturity stages increased. Compared with MTCS, MTPS significantly improved rice milling and appearance quality, decreasing density was also beneficial to rice milling and appearance quality, while grain content of amylose and protein were not sensitive to both transplanting method and planting density. Consequently, MTPS with 13.8 cm plant spacing is a suitable mechanical transplanting method for Nanjing 2728 to obtain better yield and quality under rice–crayfish continuous production system.

Manufacturing Information

Real-time information feed describing the state of production system is the key to successful management of any company, because up-to-date information is necessary basis for decision making in company operating on globalised market. Data describing the state of the production system should be collected in the manufacturing system, pre-processed, interpreted, filtered, archived and finally, either used in IT systems supporting company management (MES, ERP), or directly presented to crew and managers responsible for specific areas of interest. Possibility of data acquisition in companies strongly depends on specific of branch of industry, technological processes automation level, number of operations performed manually, type of production, etc. Acquisition of data on state of the production system should be carried-on automatically, without involvement of workers. This paper presents overall description of issues of data acquisition in company, proposed Manufacturing Information Acquisition System (MIAS) and the case study of data acquisition in company leading continuous, automated production processes Central Wastewater Treatment Plant (WWTP) in Gliwice, Poland.
