Abstract Piglet weaning weight is a critical factor that influences post-weaning growth and performance. Weaning weight is a function of birth weight and the amount and nutrient density of the milk consumed during lactation. Milk production is influenced by sow mammary gland development and diet consumption but may also be a biological function of teat location along the udder line. The objective of this study was then to determine the effects of piglet nursing location along the udder on overall piglet gain and weaning weight. A total of 1,078 individual piglets were observed during the nursing period at three time points during lactation. The teat pairs along the udder line were labeled from anterior to posterior (1-7, respectively) to define nursing location. At the end of the lactation period, the observed piglet nursing location was evaluated for both actual weaning weight and overall piglet weight gain during lactation. Data were evaluated by analysis of variance with the statistical model utilizing litter size as a covariate. As expected, when litter size was utilized as a covariate, there was a significant effect on piglet weaning weight (P < 0.0001), and there was both a linear and quadratic effect of location (L, P < 0.0001; Q, P = 0.0009) on both weaning weight and lactation piglet gain. Heavier piglets were weaned from more anterior teats (teat pairs 1-4), with the numerically heaviest piglets weaned from teat pair 4 (6.12 kg), with the lowest weight piglets being weaned from teat pair 7 (5.17 kg). Piglet weight gain during lactation was impacted by litter size (P < 0.0001), but nursing location did not affect lactation weight gain (P = 0.57). Due to the differences in piglet weights at weaning, it can be concluded that piglet nursing location influences overall piglet weaning weight.

ABSTRAK. Tujuan penelitian ini untuk mengukur seberapa besar pengaruh minyak ikan yang sudah terenkapsulasi terhadap kolesterol darah dan performa pada Domba. Penelitian telah dilakukan di Sub Unit Pelayanan Pengembangan Pembibitan Ternak Domba dan Kambing (SUPPPTDK) Bunihayu, Subang pada tanggal 20 Januari 2020 sampai 27 Maret 2020. Sebanyak 18 ekor domba Ekor Tipis jantan dengan bobot 15,99±0,98 kg dialokasikan ke dalam 3 perlakuan secara acak. Domba tersebut diberi ransum perlakuan yang disuplementasi dengan mikroenkapsulasi minyak ikan sebanyak 0% (P0), 2,5% (P1), dan 5% (P2). Data yang terkumpul dilakukan analisis ragam dan bila hasil berbeda nyata maka dilanjutkan dengan uji Duncan. Hasil menunjukkan bahwa mikroenkapsulasi minyak ikan dapat menurunkan kolesterol darah (P0,05), namun tidak berpengaruh nyata terhadap pertambahan bobot badan, konsumsi dan konversi ransum (P0,05). Penurunan kadar kolesterol terjadi pada kelompok domba dengan perlakuan mikroenkapsulasi sebanyak 2,5% (P1) dan mikroenkapsulasi 5% (P2). Kadar kolesterol darah masing-masing perlakuan berturut-turut adalah 100,70 mg/dl (P0); 96,20 mg/dl (P1); dan 78,76 mg/dl (P2). Rataan yang terbaik pada pertambahan bobot badan, konsumsi bahan kering harian, dan konversi ransum terdapat pada P2 yaitu 63,96 g/hari, 574,13 g/hari, dan 9,08. Hasil penelitian dapat disimpulkan bahwa mikroenkapsulasi minyak ikan dapat menurunkan kolesterol darah, dengan penurunan tertinggi pada pemberian 5%.  (The impact of microencapsulation fish oil in feed on blood cholesterols and performance on sheep) ABSTRAK. This study measured the effect of encapsulated fish oil on blood cholesterol and sheep performance. The study was conducted at the Bunihayu Sheep and Goat Breeding Services Bunihayu, Subang on January 20, 2020 to March 27, 2020. A total of 18 male thin-tailed sheep 15.99±0.98 kg were allocated randomly into 3 treatments. The sheep were given feed supplemented with fish oil microencapsulation of 0% (P0), 2.5% (P1), and 5% (P2). The data were collected and analyzed by analysis of variance and, if the result is significantly different, continued by Duncan's test. The results showed that fish oil microencapsulation decreased blood cholesterol levels (P0.05). However, it did not affect body weight gain, consumption, and feed conversion (P0.05). Decreased levels of cholesterol occurred in the group of sheep with 2.5% microencapsulation (P1) and 5% microencapsulation (P2). Blood cholesterol levels of each treatment were 100.70 mg/dl (P0); 96.20 mg/dl (P1); and 78.76 mg/dl (P2), respectively. Averagely, the highest body weight gain, dry matter intake and feed conversion were found in P2 as much as 63.96 g/day, 574.13 g/day, and 9.08, respectively. The results can be concluded that microencapsulation of fish oil can reduce blood cholesterol, with the highest decrease at the level of 5%.

THE EFFECT OF BIRTH WEIGHT WITH THE APPEARANCE OF THE PIGLETS UNTIL WEANING. The purpose of this research is to determine the corellation of birth weight with the appearance of the piglets until weaning. This research used the method of observation. Results or data obtained in this research, piglets from each parent is divided into 3 categories: high, medium, low. Retrieval of data held on a new born piglets, piglets aged 1 week until the time of weaning. Parameters observed in this research is the birth weight of piglets per head, body weight gain, the weight of piglets, and mortality (MRTA) piglets before weaned (%). Data were analyzed and presented descriptively, which is describing and explaining the general picture of direct observation. Based on the results of this research we concluded that litter size piglets, determines how high the birth weight, weaning weight, body weight gain, and mortality. The greater the birth weight more likely to obtain a high weaning weight as in this research the highest birth weight is 1.64 kg after weaning reached 7.54 kg.

This experiment was undertaken to know the phenotypic characteristics of native sheep. The study was conducted to investigate morphometric characters of sheep in three different field sites (Naogaon, Noakhali and Tangail) and Bangladesh Livestock Research Institute (BLRI) nucleus flock through close observation, measuring and record keeping. Characteristics of body weight, body length, heart girth, wither height, fore leg length, hind leg length, head length, ear length, ear width, horn length etc were collected from mature sheep. The results indicate that the average litter size, birth weight, weaning weight and body weight gain were comparatively higher in sheep of BLRI nucleus flock than those of other three regions. The average numbers of service/conception, post partum heat period (days), age at first heat (days), age at first lambing (days), lambing interval (days) were 1.30, 34.13, 266.50, 432.72, 192.17 respectively in BLRI nucleus flock which were comparatively better than the other three regions. The average litter size, birth weight (kg), weaning weight (kg) and body weight gain (g) in nucleus flock were 1.80, 1.19, 6.74 and 60.70 consequently. The overall performance of the sheep of BLRI nucleus flock were comparatively better than the others which may be due to the result of selective breeding, improve feeding, housing, health management etc. DOI: http://dx.doi.org/10.3329/bjas.v38i1-2.9906 BJAS 2009; 38(1-2): 1-6

Two experiments were conducted to study the performance of 3- and 5-wk-weaned pigs fed creep or starter diets of differing complexity. In experiment 1, 36 litters, adjusted to seven or eight pigs per litter, were randomly allotted to four dietary treatments: no creep feed or ad libitum access to a feed of a simple, semi-complex or complex formulation during the pre-weaning period from 10 days of age until weaning at 3 wk of age. After weaning, pigs were paired by weight, within litters and treatments and each pair randomly allotted to one of the three diets. The post-weaning feeding period was from 3 to 7 wk of age. In experiment 2 the same creep and starter treatments as were used in experiment 1 were fed to 48 litters from 2 to 5 wk of age. After weaning, litter sizes were adjusted to seven or eight pigs and four litters from each pre-weaning treatment were allotted to each of the diets from 5 to 8 wk of age. In both experiments, creep feed intake was low for all three diets and though more of the complex diet was eaten in both experiments there were no significant differences in mean piglet weaning weight. In the post-weaning period, increase in diet complexity led to a corresponding increase in feed intake and weight gain. Only in the first experiment were the differences in post-weaning weight gain significant (P < 0.001). The digestibility coefficient for energy increased with an increase in diet complexity. Significant creep–starter interactions were only observed in the second experiment; the possible reasons for this have been discussed.

RELATIONSHIP OF WEIGHT BIRTH PIGLET WITH ADDITION OF AGENCY WEIGHT, WEANING WEIGHT, MORTALITY, AND LITTER SIZE WEANING IN LIVESTOCK PT. KARYA PROSPEK SATWA. This study aims to determine how much the relationship of birth weight with weight gain, weaning weight, mortality, and litter size of weaning in animal husbandry companies owned by Animal Prospects. The material used is 7 pregnant sows from Yorkshire and Landrace, with an average body weight of 140 kg which will be taken by 54 children randomly. Furthermore, this research data obtained from weighing piglets during parturition, weighing weekly during weaning and weighing when weaned and taking data on live and dead piglets during the study. The data is then processed by procentage descriptive method and evaluated by simple correlation (r) and determination (R) tests. The variables measured in the study were body weight gain, weaning weight, mortality, and weaning litter size. Birth weight has a very close relationship with weight gain and weaning weight, but litter size weaning has a very weak relation. While mortality is not related. Key words: Piglets, Birth weight, Weight gain, Weaning weight, Mortality, Litter size weaning.

Abstract A total of 109 sows (Line 241; DNA, Columbus, NE) were used to evaluate the effect of increasing dietary phytase in lactation diets, already adequate in P, on sow and litter performance. On d 107 of gestation, sows were blocked by body weight and parity and allotted to 1 of 3 dietary treatments of increasing phytase concentration (0, 1,000, or 3,000 FYT/kg; Ronozyme Hi Phos GT 2700, DSM Nutritional Products, Inc., Parsippany, NJ). The control diet contained no phytase and was formulated to contain 0.50% standardized total tract digestible phosphorus (STTD P; 0.45% available P) and 0.62% STTD Calcium (0.90% total Ca). The phytase diets that contained 1,000 or 3,000 FYT/kg were also formulated to 0.50% STTD P and 0.62% STTD Ca including the release of 0.132% STTD P and 0.096% STTD Ca. Diets were balanced for net energy and fed from d 107 of gestation until weaning (d 18 ±3). All farrowings were monitored, with farrowing duration starting at the time the first pig was born until the first dispersal of placental tissues with no subsequent pigs born. Litters were cross-fostered within treatment until 48 h post-farrowing to equalize litter size. There were no differences among treatments in sow body weight at d 107 of gestation, 24-h after farrowing, or at weaning. Sow average daily feed intake from farrowing to weaning tended to increase (linear, P = 0.093) as phytase increased. There was no evidence for difference in the number of total born pigs, as well as the percentage of stillborns, mummies, and born alive pigs at the completion of farrowing. Similarly, phytase supplementation did not influence (P &gt; 0.05) wean-to-estrus interval or litter size after cross-fostering among dietary treatments. Although not significant (linear, P = 0.226), farrowing duration decreased as added phytase increased with a decrease of 47 minutes (12%) for 3,000 FYT compared to the control. There were no differences in pig weight at weaning, but as a result of increased survivability (linear, P = 0.002), litter weaning weight and overall litter weight gain increased (quadratic, P &lt; 0.05) up to 1,000 FYT of added phytase with no further benefit observed in sows fed 3,000 FYT. In conclusion, sow feed intake tended to increase linearly with increasing added phytase. Feeding 1,000 FYT/kg maximized overall litter gain and weaning weight; however, a larger scale study with more sows is needed to determine the addition of phytase in lactation diets to reduce farrowing duration.

The Impact

The paper provides new survey evidence on effects of concentrated ownership upon investment and performance in Russian industrial enterprises. Authors trace major changes in their ownership profile, assess pace of post-privatization redistribution of shareholdings and provide evidence on ownership concentration in the Russian industry. The major econometric findings are that the first largest shareholding is negatively associated with the firm’s investment and performance but surprisingly the second largest shareholding is positively associated with them. Moreover, these relationships do not depend on identity of majority shareholders. These results are consistent with the assumption that the entrenched controlling owners are engaged in extracting "control premium" but sizable shareholdings accumulated by other blockholders may put brakes on their expropriating behavior and thus be conductive for efficiency enhancing. The most interesting topic for further more detailed analysis is formation, stability and roles of coalitions of large blockholders in the corporate sector of post-socialist countries.

The State of Qatar has implemented several family policies in order to improve the wellbeing of Qatari families and ensure fair distribution of development benefits for both men and women. However, there is a linkage between female employment outside the home and instability in the marriages of Qatari families. This paper investigates the impact of female employment on marital stability, based on the results of primary data collected in Qatar, a questionnaire that consisted of several sections such as challenges in the workplace, supervisor, family and spouse relations, work motivation and performance. Of the 824 questionnaires that were returned, 807 were completed and valid for analysis. Regression analysis and an ANOVA test have been used to test the relationship between the variables. The results of the research have produced mixed findings about how wives’ employment increases marital instability and have yielded few significant differences on mean scores of discuss on work demands, insufficient time together, housework, financial matters, communication, relatives and rearing children. The results indicates that in general Qatar working women face several challenges in relation to their marital life as part of cultural and social constraints.

Abstract Agri-food systems include branching ramifications, which connect in the upstream the input suppliers with farmers, and downstream farmers, processors, retailers and consumers. In the last decades, at the level of the regions, food systems have undergone rapid transformation as a result of technological progress. The paper analyzes the changes made to the structure, behavior and performance of the agri-food system and the impact on farmers and consumers. Also, the role of agricultural research as a determinant factor of transformation of agri-food system is analyzed. The research objective is to develop technologies that cover the entire food chain (from farm to fork) and meet the specific requirements of consumers (from fork to farm) through scientific solutions in line with the principles of sustainable agriculture and ensuring the safety and food safety of the population.
