Piglets from 51 litters were weighed weekly over a 5-wk lactation in an experiment that studied the effects of farrowing crate design and other factors on variation in piglet weight. Of two farrowing crates used, one had low horizontal bars that tended to impede access to the upper row of teats, while the other had angled vertical bars which permitted freer access. Fourteen-day weights were more uniform in the vertical-bar crates than in the horizontal-bar crates (P < 0.025), but the difference waned by day 35 (P > 0.05). There were no significant differences in mean body weight owing to crate type (P < 0.05) for any of the weekly measurements but, by day 14, there was a significant linear trend (P < 0.05) at decreasing mean body weight with increasing litter size. The interaction between crate type and litter size was significant at the later ages (P < 0.01 at day 35) because the linear trend was more pronounced for horizontal-bar crates than for vertical. Litters differed greatly in the uniformity of their body weights. Much of the variation became established in the first and, to a lesser extent, the second week after birth. In those weeks, weight gains were highly variable and were not closely related to weight at the beginning of the week. Thereafter, the established differences tended to be perpetuated to 35 d, because weight gains were largely proportional to body weight. Within-litter competition appeared to influence weight gain considerably. Key words: Piglet, body weight, suckling behavior, sow, farrowing crate design, litter size

Background: Wasting is a common feature in tuberculosis and treatment is aimed at achieving weight gain in pulmonary tuberculosis patients. The aims and objectives of the study were to study the extent of body weight gain during treatment and to identify the effect of different factors on weight gain among TB patients.Methods: The study was conducted on a total of 326 patients residing in the area of PHC Verka and registered with District Tuberculosis Centre, Amritsar. Weight change was assessed by taking the difference of weight at initial diagnosis and after completion of continuation phase therapy.Results: A total of 228 patients participated in the study. The mean (±SD) body weights (in kg) for the patients were 44.92±12.7 at diagnosis and 48.79±12.9 at the end of treatment. The mean (±SD) weight gain was 3.86±4.55 kgs at the end of treatment. The gain in weight at the end of treatment was associated with supervision of treatment and outcome of the TB patient.Conclusions: The findings showed that there is an association between gain in weight with supervision of treatment and outcome of the TB patient.

Two experiments were conducted to evaluate naked oats as a feedstuff for male chicken roaster and female turkey broilers. In exp. 1, grower and finisher roaster diets were formulated to contain 18, 36, 54, or 72% naked oats (Avena nuda L. 'Tibor'). The starter diet contained no naked oats. Two trials were conducted utilizing 1344 birds. Treatment diets were fed to four pens of roasters each, from 21 to 64 d of age. In exp. 2, grower and finisher turkey diets were formulated to contain 0, 22, 44, or 66% naked oats. The starter diet contained no naked oats. Two trials involving 964 birds were conducted. Treatment diets were fed to four pens of turkeys each, beginning at 21 d of age. Level of naked oats did not affect weight gain, feed efficiency or mortality of the roasters. The turkey poults consuming the 66% naked oats diet had significantly heavier 10-wk body weights and greater weight gains from 3 to 10 wk of age than those fed the other diets. In Trial 1, treatment had no significant effect on weight gains or feed efficiency for the finishing period (10–16 wk). In Trial 2, birds fed the 66% naked oats diet consumed significantly less feed than those fed the other diets, and had significantly heavier 12-wk body weights than birds fed the 22 and 44% naked oats diets. Treatment had no significant effect on weight gain or feed efficiency for the finishing period (10–12 wk). It appears that naked oats were a suitable feedstuff for the birds in this study.

Black Bengal Goat

The present investigation was carried out to detect the status of different productive and reproductive parameters of Black Bengal and Crossbred goats at Bandaikhara village under Atrai Upazilla of Naogaon district during the period of September to December/2005. The average age at first sign of heat of Black Bengal goats was better than that of Crossbred goats. In Black Bengal goat the average age at first kidding was 360.5±10 days, whereas, in crossbred goats it was 411.5±15.5 day. Significantly (P<0.01) lower the post partum heat period in Black Bengal goat than the crossbred goat. The average kidding interval in Black Bengal and Crossbred goats were 179±20 and 270±22 days respectively and differences are statistically significant (P<0.01). The usual numbers of kids at one time in Black Bengal goats vary from single to quadruplet. On the other hand, litter size of crossbred goat was single or twin. The average birth weight of Black Bengal goat was lower than Crossbred goats, which are statistically significant (P<0.05). The average body weight gain after 365 days is better in Crossbred than Black Bengal goats and statistically significant (P<0.01). The average milk yield in Crossbred goat was 1.05 liter/day, whereas, in Black Bengal goat, it produces milk that only nourished its kids. It was concluded that the reproductive performance like early maturity, larger litter size, shorter postpartum period, minimum kidding interval are better in Black Bengal goat. On the other hand productive performance like higher birth weight, maximum body weight gain, high milk yield, longer lactation length are suitable in crossbred goat.

The aim of our study was to evaluate the effects of chosen factors (crossbreds, sex, litter size, age of ewes and interaction between sex and litter size) on the growth of lambs crossbreds of the breeds Charollais (Ch), Suffolk (Sf) and Improved Valachian (IV). The evaluation was performed in the year 2004 on the farm Růžďka and involved altogether 96 lambs. The growth ability was evaluated at the following crossbreds: Ch x Sf (n = 28), (Ch x Sf) x Sf (n = 28), IV x Sf (n = 21) and (IV x Sf) x Sf (n = 19). All lambs under study were born indoor in January. Lambs were kept indoor till the end of the evaluation. From the evaluation of effects of crossbreds, sex and age of ewes on the live body weights and daily gains of lambs above all result that these factors showed a significant effect only on the live body weight at birth. On the other hand, the factors of litter size and interaction between sex and litter size showed a highly significant (P < 0.01) effect on the live body weights of lambs at birth, at 70 and at 100 days of age as well as on their daily gains within the intervals from birth to 70 and 100 days of age. It can be concluded that the daily gains were highly uniform but relatively low in all crossbreds under the study within the time interval from birth to the age of 100 days, while the non-significantly highest daily gain was recorded in the crossbreds of IV x Sf (211 g). On the other hand the lowest ones were observed in the crossbreds of CH x Sf and (IV x Sf) x Sf (199 g).

The main aim of the study was the evaluation of the growth, meatiness and fattiness in vivo in lambs (n = 122) of chosen breeds (CH: Charollais and T: Texel) and crossbreeds (CH x Sf (Suffolk), CH x T, EF (East Friesiane) x CH and EF x T. Whithin the frame of this study were also evaluated the effects of sex (S), litter size (LS), age of the dams (AD) and year of the observation (YO) on aforementioned indicators. The study was carried out on the farm in Kunčice pod Ondřejníkem during the years 2004 and 2005. Within the scope of evaluation of meatiness and fattiness in vivo in lambs the following ultrasound measurement were carried out: area (Am.l.l.t., in cm2) and depth (Dm.l.l.t., in mm) of musculus longissimus lumborum et thoracis (m.l.l.t.) and fat thickness (FT, in mm). Genotype had a significant effect on body weight at birth and on daily gains (DGs) from 30 to 100 days of age and from birth to 100 days of age. Sex had a significant effect on most of body weights under study and on DGs from birth to 30 days of age, from 30 to 70 days of age and from birth to 100 days of age. The LS, AD and YO had a significant effect on most of growth indicators under study. Genotype had a significant effect on Am.l.l.t. at the age of 70 days, Dm.l.l.t. and FT at the age of 100 days. The S had a significant effect on Dm.l.l.t. and Am.l.l.t. at the age of 70 days and on Am.l.l.t. at the age of 100 days. The LS and YO had a significant effect on most of indicators of meatiness and fattiness in vivo under study. On the other hand only the AD had not significant effect on all parameters of meatiness and fattiness.

The monthly wool growth of three groups of rams was studied at Beltsville, Maryland. Group I received natural daylight (at 38° 53' N.) and was shorn monthly. Group II had a 7:17 hours of daylight to hours of darkness rhythm and was shorn every 6 months, once in winter and once in summer. Group III received natural daylight and was likewise shorn every 6 months. The rams of all groups produced more wool in summer than in winter. This difference was significant (P<0.001). The mean body weight and food intake were both greater in the winter months, which indicated that the seasonal rhythm of wool growth was not a consequence of poorer feeding in winter. The rams which were shorn monthly (group I) grew considerably more wool than the other two groups, but the difference was not statistically significant. The short-day treatment of group II did not increase the annual wool production nor decrease the seasonal rhythm of wool growth. The balance of evidence from this and other experiments indicates that temperature rather than light controls the seasonal rhythm of wool growth.

The purpose of this study was to evaluate the growth performance of cross-breeding of Belgian Blue (BB) and Ongole Grade (PO) cattle in the first generation (F1). Crossbred of BB and PO cattle used as many as 15 individuals consisting of 6 males and 9 females, also, 8 individual PO females are used which are kept in the Livestock Embryo Center (BET) Cipelang, Bogor. The observed variables were birth weight (BW), weaning weight (WW) 205 days, 1-year weight (YW) 365 days, daily body weight gain from birth (GBW) to weaning (GWW) and daily body weight gain from weaning (GWW) until the age of 1 year (GYW). Data were analyzed descriptively and the difference between cross-breeding (BB-PO) cattle and PO cattle was analyzed by t-test. The results of body weight and growth analysis showed that crossbred BB and PO cattle were higher than PO cattle at WW 205 days (165.2 ± 21.3 kg and 115 ± 15.2 kg), YW (365 days) (240.7 ± 28.1 kg and 194.9 ± 26.1 kg ) and GBW to GWW (0.675 ± 0.097 kg and 0.441 ± 0.059 kg). BW and GWW to GYW do not differ between crossbred BB-PO and PO cattle. The results of this study indicate that the cross-breeding program for BB cattle with PO cattle breeds can improve the performance of body weight and growth.

Breed effects on live weight gain, slaughter characteristics and carcass composition were compared in Aberdeen Angus, Charolais, Hereford and Simmental bulls. The experiment extended over 2 years and involved totally 96 animals. The target slaughter live weights were determined 550 kg for earlier maturing breeds Aberdeen Angus and Hereford and 630 kg for later maturing breeds Charolais and Simmental. Charolais and Simmental gained more rapidly (P &lt; 0.05) than Aberdeen Angus while Hereford were intermediate. Hereford had lower (P &lt; 0.05) dressing percentage than the other breeds. Percentages of grade I meat were significantly higher (P &lt; 0.05) in Charolais and Simmental. The highest percentage of separable fat was recorded in Hereford (P &lt; 0.05). Charolais and Simmental had lower (P &lt; 0.05) thickness of subcutaneous fat over MLLT than Aberdeen Angus andHereford. The later maturing bulls generally tended to achieve higher live weight gains during the experiment, produced less fat and had higher percentage of meat from high priced joints in comparison with earlier maturing animals. &nbsp;

Heat stress and competition for food are two major challenges in pigs reared in intensive conditions. The aim of the present work was to study the effect of providing a double feeder for pigs reared under two different environmental temperatures. In addition, two types of flooring, of 100% slat and 30% slat 70% concrete, were also considered. A total of 256 pigs in the growing-finishing period (from 27 kg to 110 kg) were housed using two environmental temperatures: control (from 18 °C to 25 °C) and heat stress (above 30 °C six hours a day). They were housed in 32 pens of 8 pigs each, distributed into 4 rooms (16 with one feeder and 16 with two). Pigs subjected to temperatures above 30 °C up to six hours had lower body weight gains than pigs subjected to a maximum temperature of 25 °C, confirming that thermal stress negatively affects performance in pigs. In addition, heat stress affected the final product by decreasing the lean percentage of carcasses by 2.6%. A double feeder reduced the presence of negative social behavior, especially in the feeding area, but body weight was lower than when one single feeder was used. A 30% slat 70% concrete floor showed better results in the pig stress indicators and body weights than 100% slat. It is concluded that providing a double feeder in the pens, although reducing the presence of negative social interactions, negatively affected body weight, in comparison to pigs fed with just one feeder.
