Similar improvements in reproductive performance of male line, female line and parent stock broiler breeders genetically selected in the UK or in South America

A study was carried out to monitor the effect of feed manipulation on the growth and development of male and female line Hubbard broiler parent stock reared under tropical open sided poultry house without any form of cooling system or any temperature regulating mechanism. A total of 255 females and 105 males for the male line and 360 females and 150 males for the female line were used. The birds were fed a normal soya cake/groundnut cake and maize based broiler starter ration of 2900kcal/kg ME and 20% CP and a grower ration containing 2650kcal/kg ME with 16% CP as stipulated by the Hubbard rearing guide. The birds were fed ad libitum for the first 2 weeks and thereafter placed on restricted feeding in line with the standard rearing guideline provided by the Hubbard breeding company for optimum growth and development. It was observed that the body weights of the birds did not differ much from the standard body weight expected at 20 weeks even though they were reared in the normal tropical open sided poultry house without sophisticated modern facilities. This shows that feed manipulation can be used to achieve desired weight in broiler parent stock rearing

Abstract We study the largest exposed example of an early Cambrian palaeokarst, associated with laterites and developed during rifting of the Ossa–Morena Zone. The lithostratigraphy, biostratigraphy, facies and the genesis reflect episodes of sea-level fall (Cerro del Hierro Regression) related to tectonic events and palaeoclimate. This palaeokarst can be primarily considered as the result of early Cambrian polyphase karstification in an extensional tectonic regime, later modified by Neogene–Quaternary geomorphological processes. The event may correlate with other regressive events of a similar age in Spain, Italy, United Kingdom, South America and Australia. This episode also has local names (e.g. Cerro del Hierro Regression in the Mediterranean region; Woodlands Regression in the UK). It is sometimes accompanied by additional karst development outside of Spain that is compared and interpreted in a global context.

Farm Livestock

The role of stockmanship in relation to the wellbeing of farm animals has been emphasised in the UK Codes of Recommendations for the Welfare of Farm Livestock (MAFF, 1983). Moreover, previous research work has demonstrated important effects of good and bad stockmanship not only on welfare but also on growth, lactational and reproductive performance of pigs and other farm livestock (Hemsworth et al, 1987). There is a need, therefore, to establish the factors which motivate and demotivate stockpeople since the degree of job satisfaction is likely to have a considerable influence on the attitude and performance of stockpeople and on their empathy with the animals in their care. With this objective in mind, a questionnaire was designed to investigate the aspects which could have an influence on the job satisfaction of the stockpeople involved in pig production.

This paper explores the female line in the Bible that Joseph Ratzinger identifies as running in parallel to, and being indispensable for, the male line in the Bible. This female line expands the understanding of Salvation History as described by Dei Verbum so that it runs not just from Adam through to Jesus, but also from Adam and Eve to Mary and Jesus, the final Adam. Ratzinger’s female line demonstrates that women are at the heart of God’s plan for humanity. I illustrate that this line is evident when Ratzinger’s method of biblical interpretation is applied to the women of Scripture. Its full potential comes into view through Ratzinger’s development of the Christian notion of person: Person as revealed by Jesus Christ is relatedness without reserve with God and is fully applicable to the human being through Christ. I argue that together, the male and female lines in the Bible form the human line in the Bible, in which the male line represents “the humanity”, every human being, while the female line represents the communal aspect of humanity. Moreover, I contend that Christianity’s notion of mother in relation to God (as Father, Son and Holy Spirit) should be understood through Mary’s response at the Annunciation. Mother in relation to God is to be understood through the Incarnation when Mary, as person, lived her life wholly in relation with and for God.

AbstractThe objectives of this study were to investigate reproductive performance and the influence of maternal environment on reproductive performance in two genetic lines of maiden heifers. These were given food and managed in the same way at the Langhill Dairy Cattle Research Centre. The two genetic lines were established in 1973; one has been selected for high combined yield of fat plus protein (selection line; S) and the other has been maintained at around the UK average for genetic merit of yield of fat plus protein (control line; C). Analysis of the reproductive performance of 988 heifers born between 1981 and 1998 showed that S heifers were poorer (all P < 0·05) than C heifers for all reproductive measures: conception at first service (S: 0·64, s.e. 0·02; C: 0·71, s.e. 0·03), interval between first and last service (S: 18·2 days, s.e. 2·2; C: 13·4 days, s.e. 2·2) and number of services per conception (S: 1·49 services, s.e. 0·06; C: 1·39 services, s.e. 0·06). S heifers were also younger at first service than C heifers (474·9 days v. 480·1 days, s.e. 1·9, for S and C respectively; P • 01). Fertility of service sires may have had some influence on these results, but this could not be investigated here, as S heifers were mated only to high merit bulls and C heifers to average merit bulls. However, within genetic line, the yearly downward trend in the average number of services per conception of heifers was significantly different from zero for the S line, but not the C line. There were no statistically significant relationships between conception rates in maiden heifers and their subsequent reproductive performance in first lactation. The effect of maternal environment on the reproductive performance of daughters as maiden heifers was investigated. There were no statistically significant relationships between daughter reproductive performance and dam parity or the feeding system of the dam (either a high or low level of concentrates). Within the limited range of nutritional status of dams during the periods post calving and in early pregnancy, there was no statistically significant effect of maternal nutrition on daughter reproductive performance.

Fertility Traits

Fertility traits have been included within breed selection programmes for the Norwegian Red (NR) dairy cow population in Norway for over thirty years. As a consequence, a 60 day non-return rate to first artificial insemination (AI) of 72.5% was recently calculated for NR cows in Norway (Garmo et al., 2008). In view of this long term breeding programme, and current fertility performance within Norway, there is considerable interest in the NR breed as a means of overcoming the high levels of infertility that currently exist within the Holstein-Friesian (HF) breed. However, farming systems within Norway are very different from those within the UK, with herd sizes in particular being much smaller. Thus an experiment was established on 19 commercial dairy farms to compare the fertility performance of cows of the NR and HF breeds.
