SummaryThe influences of the temperature during plant raising and the age of plants at transplanting on the time of hearting and head weight at maturity of the crisp lettuce variety Saladin R100 were determined in seven experiments between 1984 and 1986.Plants raised at ambient temperatures and transplanted before the end of May produced heads which were heavier and matured later than those from plants raised at higher temperatures under glass. The influence of transplant age on head weight was much smaller than that of raising conditions and there were inconsistent effects on the time of crop maturity. When the head weights at maturity of all treatments were considered there were highly significant positive correlations with total solar radiation in the periods 7 and 10 days before 50% hearting occurred. Further examination of this effect revealed that heads heavier than 800 g were strongly associated with mean daily solar radiation exceeding 15MJ/m2 in the periods 7 and 14 days before 50% hearting. This suggests that breeding for stability of head weight from crop to crop is likely to be aided by selection for consistency of head weight under a range of light levels in the prehearting phase.The coefficient of variation of the period from transplanting to maturity, measured in terms of various environmental characters, was lowest using effective day-degrees, which take account of different levels of solar radiation at the same mean temperature. This suggests that effective day-degrees may be the best indicator of the duration of crop growth and therefore of benefit in developing techniques to predict the time of crop maturity.

1. The effects of different levels of first winter nutrition over 3 years were studied from 18 months to maturity on the growth and development of groups of North and South Country Cheviot ewe hoggs (sheep between 6 months and 1½ years).2. Differences in live weight amongst treatment groups within breeds and years were not significant at 30 months or any subsequent age. Live weight increase continued up to 54 months. Although leg growth had virtually ceased in all treatment groups by 18 months, body growth continued beyond 27 months and differences between treatments, although not always significant, were still present at that time.3. The effects of first-winter treatment were also studied on the heavy and light hoggs (i.e. those above and below average weight) prior to treatment. Differences in weight and size between treatment groups were less persistent in the heavy animals, disappearing by 30 months, while in the light animals they were still present at that time. Regardless of treatment the within-group differences between heavy and light animals increased up to 54 months, the light animals showing relatively slower rates of gain.4. The difficulty of interpreting data on liveweight change due to age, state of maturity, level of feed, and season interactions is commented on. The probable effects of differential productivity resulting from treatment on growth and development from 18 months onwards are discussed.

<p>We determined the optimal content and ratio of threonine and tryptophan in the mix fodder of replacement chicks at different periods of their growing. We studied the effect of different levels of threonine and tryptophan in mixed fodder on chicken growth and development. We registered that under optimal AA content and ratio the replacement chickens at the end of the growing period outweighed the chickens from control group by 140 g. We also studied the influence of different content of AA and temporal changes in their ratio on digestibility of feed nutrients by replacement chickens from market egg flock. It was found that the optimal content of threonine and tryptophan and their ratio at certain periods of chicken growth caused the increase in digestibility of protein by 2 %, fiber – by 1 %, and BEV – by 2 %. We also proved that the decrease or increase of AA ratio in mix fodder of replacement chickens leads to the manifestation of antagonism between amino acids and the deterioration of their function in bird organism. The changes in AA ratio had significant effects on chicken productivity, the digestibility of feed nutrients, the assimilation, and efficiency of amino acid use. This effects were considerably stronger than the effect of changes in AA content. The degree of influence of the ratio between threonine and tryptophan varies throughout the growing period, it has been established that the ratio of threonine to tryptophan in the period of limited chick feeding (9-6 weeks) has a lesser effect on the productivity of repair young (R<sup>2</sup> = 0.89) the second one (R<sup>2</sup> = 0.92) and the last growing periods (R<sup>2</sup> = 0.92). We performed a mathematical model (polynomial trend line) to describe the growth of replacement chickens during all experiment periods, the pattern of dependences between chicken organism and AA content, AA ratio, age, and productivity. This nonlinear model is more relevant and reliable than linear dependence.</p>

The experiment is carried out on 3 groups of cows (1 - with productivity up to 7500 kg, 2 – from 7500 to 9000 kg and the 3rd group-9000 and above kg of milk for the previous lactation). Milk yield for 305 days of lactation of cows of group 3 averaged 9068 kg (P≤ 0,01), group 2-8682 (P≤ 0,05) and group 1 – 7940 kg of milk. Milk fat production in cows of group 3 - 369 kg (P≤ 0,05), group 2-351 and group 1 – 326 kg. The yield of milk protein from cows of group 3 is 285 kg (P≤ 0,01), group 2-270 (P≤ 0,05) and group 1-248 kg. A comparative analysis of the growth and development of heifers with mothers with different levels of productivity was carried out. At the 2nd month of growing, the weight of heifers of the 3rd group is 76 kg (P≤0,10), the 2nd - 72 kg (P≤0,10). The average daily growth of group 3 heifers at 6 months was 1244 g (P≤0,10), group 2 - 1127 and group 1-617 g.Group 3 Heifers at 9 months weighed 301,2 kg (P≤0,05), group 2 – 299,3 kg (P≤0,05). Heifers of group 3 at 12 months reached 380,6 kg (P≤0,05), group 2–378,5 (P≤0,05) and group 1 – 353,7 kg. The growth of experimental heifers of group 2 was 887,6 g (P≤0,05), group 3–829,6 and group 1 – 710 g per day. Monitoring of growth and development of heifers continues.

Business tourism is the oldest form of tourism in human history. Business tourism is based on four types of activities i.e. meetings, incentives, conferences, and exhibitions (MICE). The inbound business tourism performs a significant role in the economic growth and development of any country. The objectives of this chapter are as follows. First, to highlight the key constraints of inbound business tourism in Pakistan. Second, possible and suitable remedies to resolve these constraints. Third, to explain the importance of inbound business tourism from the perspective of the China-Pakistan economic corridor (CPEC). The present chapter divides the constraints of business tourism in Pakistan into four levels, namely: state-level constraints, government level constraints, industrial level constraints, and individual-level constraints. This study proposes different remedies against different levels of constraints such as an establishment of an international platform of business tourism of Pakistan.

The paper presents the results of a study of more than 3.5 thousand teachers of kindergartens and three levels of school education using the method of questionnaire. The study was focused at teachers’ knowledge in the field of pedagogical physiology and physiology of development. No significant differences were revealed between teachers of different levels of education; there was no correlation between the level of knowledge and teachers’ experience or age. The subject area the teachers work in have a certain nfluence on the level of knowledge: biologists and the teachers of physical education give correct answers more often than other teachers. In general, the correct answers to the questionnaire were given by 50-60% of the respondents. The most difficult questions concerned the dynamics of growth and age-related periodization in the ontogeny. The results of the study may be used to develop the content and the structure of a training course for teachers’ additional education "Growth and development of a child"
