1. A method is described suitable for the estimation of the milk yield of sheep under natural grazing conditions.2. The yields obtained from Welsh Mountain sheep in two environments are shown.3. A close but diminishing relationship is shown to exist between the milk yield of the ewe and the growth of the lamb. Evidence is given of the effect of milk yield at later stages.4. The estimation of the ewe's milk yield from the weight of the young lamb is discussed. These estimates are used in conjunction with actual milk records in the present study.5. The ewe's milk yield is shown to be significantly related to nutrition, body weight, udder size and the lamb's birth weight.6. The relation of milk yield to weight gain during lactation, fleece weight and fleece type were mainly non-significant.7. From the limited data available, it seems that milk yield has a fairly high repeatability and heritability.

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.

Fleece Weight

1. The influence of seasonal, maternal and genetic variation on body weight and fleece characters of Welsh Mountain sheep is reported.2. Fertility and rearing ability of ewes improved from first to third lamb crop.3. Male lambs were on average 0·4 lb. heavier at birth than females. Birth weight increased with number of pregnancies of the dam.4. Early growth of the lamb between birth and marking (24 days old) used partly as a measure of milk production of the ewe, was greater in males than in females. Lambs born to older ewes made the greatest gains over this period, although the trend was not significant.5. Weaning weight of the lamb was affected by the dam's weight at tupping, the number of preceeding pregnancies, her milk yield and also by the season in which the lamb was born. Despite these effects weaning weight proved a good guide to the weight (at subsequent matings) at 1½ and 2½ years old.Heritability by intra-sire parent-offspring regression was 0·51±0·07 (P<0·001) and repeatability was 0·43 (P<0·001).6. Fleece weight was not affected by season or age of ewe. However, the heaviest lambs at weaning tended to have heaviest fleeces the following year.Heritability by intra-sire daughter-dam comparison was 0·58±0·11 (P<0·001) and repeatability was 0·46 (P<0·001).7. Staple length measured on the mid-side of the animal had a repeatability between years of 0·56 (P<0·001) while heritability by daughter-dam regression was 0·38±0·ll (P<0·001).8. Fourteen Welsh Mountain rams were progeny tested. Nine of the rams were purchased at local sales and 5 were home bred. They were not selected for the traits examined.No statistically significant differences were obtained between sire progeny groups for weaning weight and fleece weight.

Mixed Breed

We tested whether the milk yield capacity of mixed-breed goats on a Chihuahuan desert rangeland in northern Mexico during the dry season affects milk composition, body weight gain, and weaning weight of their progeny. Milk yield and composition, and progeny postnatal growth performance, were recorded weekly. One week after kidding, mixed-breed goats (a mixture of Criollo × dairy breeds; n = 40) were allotted into medium (MP) or low (LP) milk yielding groups (20 goats per group). Mean 105-d total milk yield for MP and LP goats was 45.2 ± 12.5 and 20.7 ± 5.2 L, respectively. Milk lactose (4.3 vs. 4.2%) and solids-non-fat (SNF; 8.2 vs. 8.0) differed (p < 0.05) between MP and LP goats; milk protein content tended to differ (p = 0.08) between MP and LP goats with no difference for milk fat content (p > 0.05). Maternal body weight was positively associated with milk yield, milk lactose, and SNF content (p < 0.05 to p < 0.001). Goats giving birth to males produce more milk than goats giving birth to females, but milk fat percentage was higher in goats bearing females (p < 0.001). Milk yield and composition throughout lactation did not influence body weight gain (47.8 vs. 48.7 g/day for kids from MP and LP goats) and weaning weight (6.7 vs. 6.7 kg from MP and LP goats) of the offspring (p > 0.05). Birth weight and weaning weight of the progeny were positively related to maternal body weight (p ≤ 0.05). The postnatal growth of the kids was reduced, extending the time to reach market weight. Nevertheless, non-supplemented mixed-breed goats reared on semi-arid rangeland of northern Mexico have the potential for moderate milk production. Therefore, due to the limited nutrients ingested by grazing goats during the dry season, a nutritional supplement is necessary to keep up milk production and adequate growth of kids.

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.

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.

Causes Of Mortality

This study investigates the relation between birth order (BO), birth weight (BW0), colostrum intake (CI), level of passive immunity and pre-weaning mortality of piglets. The animals used were 551 cross-bred piglets [Piétrain × (Large-White × Landrace)] born from 40 sows. Colostrum immunoglobulins G (IgG) determinations were made from 17 sows. Colostrum samples were obtained at birth of the first piglet then at 3, 6, 12, 24, and 36 h later, and on the first-two and the last-two piglets born. Serum IgG determinations from 68 piglets were made at 2d of age and at weaning. Individual CI was estimated from body weight gain. Relative birth order (RBO) and BW0 within-litter were weakly (R2<0.05) but positively correlated (p<0.01). Colostrum intake of piglets was independent from RBO (p>0.10) but increased by 26 ± 1.6 g per 100 g increase in BW0 (p<0.001). Serum IgG concentrations of the last two born piglets were 29.5% lower (p<0.01) than the first two born at 2 d of age, and 25% (p<0.05) at weaning. They were also lower at weaning than at 2 d of age (p<0.001). Serum IgG concentrations of piglets at weaning and at 2 d of age were positively correlated (R2=0.50, p<0.001). Within-litter, CI explained 11% (p<0.01) of the variation observed in piglets’ IgG at 2d of age. Mortality of piglets was irrespective of RBO (p>0.10). It was concluded that despite last-born piglets obtained less passive immunity than first-born, they were not at higher risk of dying before weaning. Major causes of mortality were low birth weight and insufficient colostrum (energy) intake.

THE EFFECT OF INFANT MASSAGE STIMULATION TOWARDS THE WEIGHT GAIN ON INFANTS WITH LOW BIRTH WEIGHT IN YOGYAKARTADwi Nur Octaviani Katili1, Djaswadi Dasuki2, Retno Mawarti3Universitas Muhammadiyah GorontaloEmail: [email protected]: Infants with low birth weight (LBW) require more nutrients inputs in order to optimize their growth and development. The increase of infants weight is used as the best indicator to determine the growth of infants with LBW. The massage on infant with LBW is a form of stimulus/kinesthetic tactile stimulation as a verbal communication to the infants. It can increase endurance, the activity of the digestive function, and the activity of the vagus nerve.Objective: To determine the benefits of infant massage stimulation as an effective non-medical way in gaining body weight on infants with low birth weight (LBW).Methods: The design of the study is Randomized Controlled Trial. The sampling technique is concecutive sample with the total samples are 15 respondents for each group (treatment and control). The data were analyzed with bivariate analysis stage by using independent t-test with a significance level of p value &lt;0.05 as well as multivariate analysisby using linear regression.Results: The t-test results showed that there is average difference in the gaining of body weight on infants with the low birth weight in the treatment and the control group as big as 53.67 grams with a p value &lt;0.001, 95% CI = -79.02 - (- 28.38).Conclusions: The weight gain on infants with low birth weight who do massage stimulation for 14 days is greater than infants who are not massaged.

The study was conducted to know the effect of different levels of pre and post-natal nutrition on the performances of ewes and their lambs until 1 year of age and the profitable slaughter age of lambs under semi intensive system. Twenty eight (28) native Bengal ewes at 7 weeks of gestation were randomly assigned to four groups (T0, T1, T2, T3) and supplemented with a concentrate mixture at 0.0, 1.0, 1.5, 2.0% of their body weight respectively. Ewes were allowed to graze 8 hours daily. Creep mixture (20 g/lamb/day) was provided to lambs from 2 weeks age with an increment of 10 g/lamb/week. After weaning, 20 growing male lambs were selected and reared 01 year of age with concentrate mixture at 1.5% of their body weight and 8 hours grazing irrespective of treatment groups. Parameters like, ewe’s litter size, daily milk yield, post-partum heat and lamb’s birth weight, weaning weight, live weight at 06, 09 and 12 months were recorded. The data were analyzed in an ANOVA with CRD by using SPSS v. 20. The mean differences were tested by DMRT at a probability level of P<0.05. After weaning, the lamb growths were analyzed considering age as fixed factor. Regression correlations among different parameters with different ages were also performed. Significantly higher daily milk yield (P<0.01), weaning weight (P<0.05) and daily weight gain of lamb until weaning (P<0.05) were observed in T2 group. Besides, lambs weight at 06, 09, and 12 months differ significantly (P<0.01) along with corresponding daily weight gain (P<0.05). Lambs daily weight gain did not differ significantly from weaning to 09 months of age but significantly reduced (P<0.05) from 09 to 12months age. Finally, it may be concluded that a concentrate diet containing 20% CP during late pregnancy to lactation should be supplied to obtain maximum performances of ewes and their lambs. Besides, native Bengal lamb would be slaughtered between 06 to 09 months of age to get maximum return. Bang. J. Livs. Res. Vol. 26 (1&2), 2019: P. 43-50

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
