Effects of pH on blood physiological parameters and growth performance of Asian bumblebee catfish (Pseudomystus siamensis) were carried out in laboratory conditions. The experiment was set up in 8 weeks at different pH water levels. The results showed that the cumulative mortality of Asian bumblebee catfish (4 - 6 g/fish) in 24 hpi was 100% at pH = 11, 70.83% at pH = 10 and 62.5% at pH = 3. No mortality of fish was observed at pH = 4, 5, 6, 7, 8, 9 at 24 hpi. The high content of glucose was recorded in fish cultured in water with low (4.02 mmol/L at pH = 3) and high (3.22 mmol/L at pH = 10) pH levels. After 8 weeks of culture, the highest content of glucose was observed at pH = 8 (1.10 mmol/L). The daily weight gain and specific growth rate in weight of fish were 0.02 - 0.08 g/day and 0.35 - 0.99%/day, respectively. The daily length gain specific growth rate in length were 0.02 - 0.04 cm/day and 0.22 - 0.53%/day. The highest survival rate of fish was recorded at pH = 6 (95.96%) and the lowest survival rate of fish was recorded at pH = 8 (60%).

This present study makes an analysis of changing contribution of sub-sector and composition and growth performance in Indian economy. In addition to that, the contribution of sub-sector of service sector in state economy. The results revealed that the growth rate of Chandigarh was high due to providing especial emphasis on dominating sub-sectors of services and its most preferred destination for technology whereas, Sikkim and Arunachal Pradesh due to geographical and environmental conditions development were higher in floriculture and agriculture, although, tourism emerged as a new profession and have different opportunities. Apart of that, in the wake of some challenges in the form of lack of infrastructure, recent crisis in the world market, foreign direct investment (FDI) restrictions and outsourcing backlash were major limiting factor.

How to maximize the use of the genetic merits of the high-ranking boars (also called superior ones) is a considerable question in the pig breeding industry, considering the money and time spent on selection. Somatic cell nuclear transfer (SCNT) is one of the potential ways to answer the question, which can be applied to produce clones with genetic resources of superior boar for the production of commercial pigs. For practical application, it is essential to investigate whether the clones and their progeny keep behaving better than the “normal boars”, considering that in vitro culture and transfer manipulation would cause a series of harmful effects to the development of clones. In this study, 59,061 cloned embryos were transferred into 250 recipient sows to produce the clones of superior Pietrain boars. The growth performance of 12 clones and 36 non-clones and the semen quality of 19 clones and 28 non-clones were compared. The reproductive performance of 21 clones and 25 non-clones were also tested. Furthermore, we made a comparison in the growth performance between 466 progeny of the clones and 822 progeny of the non-clones. Our results showed that no significant difference in semen quality and reproductive performance was observed between the clones and the non-clones, although the clones grew slower and exhibited smaller body size than the non-clones. The F1 progeny of the clones showed a greater growth rate than the non-clones. Our results demonstrated through the large animal population showed that SCNT manipulation resulted in a low growth rate and small body size, but the clones could normally produce F1 progeny with excellent growth traits to bring more economic benefits. Therefore, SCNT could be effective in enlarging the merit genetics of the superior boars and increasing the economic benefits in pig reproduction and breeding.

Data for a total of approximately 1100 lambs tested in 12 trials from 1992 to 1995 in commercial lamb test stations in Quebec were used to determine the effect of sex, sire breed and genetic type on growth performance and carcass characteristics. Lambs were housed two to a pen and fed commercial diets. Maximum test length was 112 d. Lambs were slaughtered when their liveweight was approximately 47 ± 5 kg for the males and 43 ± 4 kg for the females. Feed intake and growth rate were measured during the test, and carcass measurements were taken at slaughter and at 24 h following slaughter. Feed intake was the average for the pen, while the growth and carcass measurements were taken individually. Males ate more per day, had better gain and were younger at slaughter than females. Females had more body fat and better carcass conformation scores than males. However, males did not have a greater loin muscle thickness compared to females. Lambs sired by Hampshire or Suffolk rams had superior growth performance and leaner carcasses than lambs sired by Dorset rams. However, Hampshire and Suffolk-sired lambs did not have a greater loin muscle thickness compared to Dorset-sired lambs. Analysis of different genetic types did not demonstrate a pronounced effect on lamb performance. No specific genetic composition was clearly superior to the others for the various variables studied. Genetic quality within a breed of sheep bought or kept for reproduction is as important as the choice of breed or the combination of breeds. Key words: Lamb, growth performance, carcass composition

Abstract Subject and purpose of work: The study aims to evaluate the growth performance of spice crops in Haryana state of India. Materials and methods: The study is based on secondary data obtained over the period of 17 years i.e., from 2001-2002 to 2017-2018. Four spice crop – ginger, turmeric, garlic and fenugreek were selected from rabi and kharif season on the basis of the largest area sown. In order to analyze the data descriptive statistics (mean and C.V.) and CGR (compound growth rate) were employed. Results: T he s tudy r evealed a significant p ositive g rowth r ate o f 2.20%, 4.50% and 2.20% in the area, production and productivity of ginger in the district of Panchkula, respectively. In the district of Yamunanagar, a growth rate 13.80% and 10.20% was found in the area and production of turmeric. However, a negative productivity growth rate of -3.20% was also revealed. A positive growth rate 1.50%, 3.30% and 0.17% was found in the area, production and productivity of garlic in Karnal district. In the district of Yamunanagar, a growth rate for fenugreek of 7.30% and 7.60% and 13.90% in the area, production and productivity was found. The state of Haryana recorded a significant growth of 1.7%, 2.8% and 1.1% per annum in the area, production and productivity of spice crops respectively. Conclusions: T he s tudy r evealed a positive g rowth rate across all the selected spice crops, indicating improving prospects of spice crops in Haryana state.
