Abstract Two types of mating had been practiced in the crossbreed of Jawarandu does and Boer buck that produced Boerja goat, the natural service and artificial insemination. This study aimed to compare the weaning rate, birth weight, and weaning weight of offspring from both mating methods and analyze the different birth and weaning weights on different sex and birth type. A total of 271 kids were born from naturally serviced (NS) and artificially inseminated (AI) does (221 and 50, respectively). All kids were managed in the same condition. The number of kid died pre-weaning, birth weight, and weaning weight were recorded and analyzed. The result showed that the weaning rate of AI kids was significantly higher than NS kids. The birth and weaning weights of kids from both groups were not significantly different. Male and single kids had heavier birth and weaning weights than female and twin kids. Overall, the survival rate of AI kids until weaning is better than NS kids. The birth and weaning weight in NS and AI are not different but male and single kids are heavier than female and twin kids in both groups.

Abstract Reproductive efficiency is critical for profitability, and age at weaning critically impacts weaning weight. The objective was to evaluate estrous synchronization and/or AI with conventional (CON) or gender-skewed (SEXED) semen on calving distribution. Beef females (n=1,620) were either 1) synchronized (7-CIDR:Syn) or not synchronized (Nonsyn) and mated to bulls, 2) synchronized (7-d CIDR) and mated to bulls (SynNS) or artificially inseminated (SynAI), or 3) synchronized (7-d CO-Synch plus CIDR) and AIed with CON or SEXED semen. Calving distribution and gender were determined at birth and were analyzed using the GLIMMIX procedure in SAS. Synchronization resulted in more calves born from d1 to 14 (P < 0.01; 62% vs 47%) of the calving season. There was no differences (P = 0.31) between Syn and Nonsyn in the percent of calves born after d21, but between d22 and 42, more (P = 0.04) calves were born in the Nonsyn group. A greater proportion (P < 0.02; 46% vs 38%) of calves were born in SynNS between d1 and 14 compared to SynAI. There was no difference between treatments (P > 0.12) from d1 to 42, but more calves were born for SynAI after d43. With SEXED semen, there were no differences (P > 0.14) between CON and SEXED for the proportion of calves born from d1 to 14 or d1 to 21; however, more of the desired gender were born in the SEXED group during d1 to 14 of the calving season (P < 0.01; 84% vs 68%). More total calves were born from d22 to 42 in the SEXED group compared to the CON group (P < 0.05; 49% vs 33%). In summary, synchronization increased the proportion of females that calved early in the calving season, and SEXED semen increased the proportion of the desired gender born early in the calving season.

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

The aim of this study was to facilitate artificial insemination training to enhance sustainable pig production within the developing smallholder pig production sector in Gauteng Province, South Africa. Eighteen smallholder pig farmers with requisite structures (pig house, pens), pigs (large white, landrace duroc or South African indigenous) and management (feeding, cleaning and record keeping) capacity were trained on routine pig management and artificial insemination procedures in a “learning by doing” on-farm supervised programme administered by Agricultural Research Council, Animal Production pig training team. Following estrus detection, 96 sows were artificially inseminated and 31 naturally served (NS). Farrowing rates (FR), total born (TB) and born alive (BA) piglets were recorded. The occurrence ccurrence of mummified fetuses (0.019 vs. 0.022%) and weak piglets (0.038 vs. 0.049%) did not differ between artificially inseminated sows and naturally mated sows. Born alive, birth weight and weaning weight were higher for artificial inseminated sows. The average litter size was 15± and 13±, birth weight 1.98±0.79 kg and 1.48±0.58 kg and weaning weight 9.89±0.87 kg and 7.23±0.71 kg for the AI and NS litters, respectively. Farmer demographic factors (age, gender and educational level) had no effect on farrowing rate, total born and piglets born alive. Therefore, implementation of artificial insemination techniques and pig production training was feasible under a smallholder pig production system.

In this study, we compared the growth and survival characteristics of Romanov × Morkaraman (F1 Rom), Romanov × F1 Romanov (G1 Rom) and Charollais × F1 Romanov (Charom) crossbreed lambs weaning weight at different ages. After birth, from three genotypes lambs were weaned at two different ages of 50 and 75 days and growth performance after weaning was examined at 120 days of age. The effect of three different genotypes and birth type on birth weight was very important, and sex effect was insignificant. In weaning weight, only the effect of birth type was found to be significant. Lamb birth and weaning weights were in Charom, F1 Rom, G1 Rom lambs, 3.38-15.28; 3.98-15.04; 3.21-15.55 kg, respectively. The type of birth showed variation in the birth weight of the lamb and the decrease in lamb birth weights (Single: 4.19 kg: Twin: 3.42 kg; Triplet: 3.15 kg and Quadrature: 2.88 kg) was observed as the number of offspring increased. The effect of the birth type on weaning weights was similar in single and triplet. Single-born lambs have higher weaning weights than those of twins and quadruplets. Average daily live weight gain (ADG) from weaning in single lambs, 247.37 g were found higher than twin (190.67 g), triplets (201.44 g) and quadruplets (178.57 g). The effect of weaning age was insignificant on weaning weights. The first month weight after weaning, effect of the genotype of the lamb, the birth type and the sex were insignificant; but effect of weaning age was significant weaning weights and first month after weaning weights the ADG. The late weaned lambs had higher next first month live weight (18.62-17.89 kg) and ADG (179.45-81.32 g). The live weights of the lambs on the 120 days were similar and none of the factors investigated were found to be effective.

AbstractGrowth and survival of 3673 female and cryptorchid lambs representing the range of types (second cross, first cross and Merino) produced in the Australian lamb industry are reported. The lambs were sired by a selection of Poll Dorset (D; no. = 7), Texel (T; no. = 10), Border Leicester (BL; no. = 12) and Merino (M; no. = 12) rams and born to Border Leicester × Merino (BLM) and Merino (M) dams, which resulted in six lamb genotypes (D×BLM, T×BLM, D×M, T×M, BL×M and M×M). The second cross lambs (D×BLM, T×BLM) were heavier at birth, weaning and post-weaning and had higher growth rates, than first cross lambs (D×M, T×M, BL×M), which were higher than M×M lambs (P< 0·01). For post-weaning weight (cryptorchids at 156 days) second cross lambs were 4·2 (s.e. 0·3) kg heavier than comparable sired first cross lambs, with the BL×M 2·6 (s.e. 0·5) kg lighter than other first cross types and the MxM a further 4·2 (s.e. 0·6) kg lighter. The average advantage of D over T crosses was 1·0 kg for post-weaning weight, with greater variation amongst individual sires.Lamb survival to weaning was 76% and it was affected by birth weight and birth type (P< 0·01). Sire breed had no significant effect on lamb survival, whereas lambs from BLM ewes had higher survival than those from M ewes (P< 0·01).Overall the proportion of ewes lambing was 84% with a mean litter size of 1·77. There was no difference infertility between AI (thawed frozen semen and laparoscopic insemination) and natural (single sire) mating, although the M were higher than the BLM ewes (P< 0·01). Gestation length was 2·3 days shorter (P< 0·01) for BLM than M ewes and there was no difference between D and T sire breeds. There was little effect of birth type on gestation length but it increased with birth weight within birth type categories. Between year repeatability of gestation length for ewes was 0·33 (s.e. 0·05).

The development of local genetic resources is important to meet the need of high demand of lamb meat in Indonesia, especially in West Java, through the selection of superior breeds of Garut sheep. The selection has to be initiated by studying the Garut sheep performances to determine the environmental factors affecting the preweaning performances of the sheep and involving those factors in the analysis of genetic parameters. The study was held on the Unit Pelayanan Teknis Dasar Balai Pengembangan Perbibitan Ternak Domba dan Kambing (UPTD-BPPTDK) Margawati Garut from August 21st to September 18th, 2019. The purpose of this experiment was to study the effect of sex and litter size on preweaning weight, i.e birth weight, weight on 30, 60, 90 days, and weaning weight (100 days). The traits were analyzed on 6.349 heads, 3.214 rams, and 3.135 ewes, from 2012 to 2019 using the General Linear Model (GLM) and Duncan multiple range test of SAS 9.0 software. The fixed effects used in the analysis were the sex and the birth type. The results showed that the performance of Garut Sheep based on the preweaning weight was affected significantly (P<0.05) by the sex, with the average of birth weight, 30, 60, 90 days weight and weaning weight (100 days) were 2.46 kg, 5.64 kg, 7.73 kg, 9.92 kg, 10.97 kg (rams) and 2.33 kg, 5.42 kg, 7.34 kg, 9.36 kg, and 10.28 kg (ewes). The pre-weaning weight was also significantly affected (P<0.05) by the birth type, in which  the average of birth weight, 30, 60, 90 days weight and weaning weight (100 days) were 2.96 kg, 6.49 kg, 8.98 kg, 11.29 kg, 12.52 kg (single), 2.25 kg, 5.09 kg, 6.78 kg, 8.71 kg, 9.52 kg (twin), 1.79 kg, 4.62 kg, 6.24 kg, 8.09 kg, 8.92 kg (triplet), 1.54 kg, 4.53 kg, 5.89 kg, 7.15 kg, 8.03 kg (quadruplet), and 1.51 kg, 3.84 kg, 5.23 kg, 6.58 kg, 7.15 kg (quintuplet). Based on the results, preweaning weight must be corrected by the sex and the birth type before the genetic parameters are analyzed to avoid bias of selection results.

Research related to the optimization of cow performans is done through concentrate feed and reproduction technology. This research was conducted in 2018 in Musi Village, Gerokgak Sub-district, Buleleng Regency, Bali. The study used a Completely Randomized Design (CRD) with 4 feed treatments and used 7 pregnant cows as replicates. The treatment is carried out when the cows enters 7 months pregnancy. Treatments tested: P0 cows given forage + rice bran 1 kg /cow/day + Bio Cas 5 ml/cow/day (mating with males), P1 = P0 cows mated with Artificial Imsemination (IB), P2 cows given forage + concentrates 1 kg/cow/day + bio cas 5 ml/cow/day (mating with a male), and P3 = P2 cattle mated with IB. Parameters observed that the parent body weight, weight gain calf, calf birth weight, weaning weight, calving interval, dry matter intake and feed rations convertions ratio. Data were analyzed by analysis of variance, if there are significant differences (P <0.05), followed by LSD 5%. The results showed that cows given feed concentrates and mated with IB (P3) result in weight gain of 0.52 kg/calf/ day was significantly higher (P <0.05) of P0 (0.40 kg/calf/day). Consumption of dry matter ration for P3 (2.59 kg) was significantly less (P <0.05) than P0 (2.87 kg) and resulted in the highest weight gain causing P3 FCR value of 4.98 was significantly lower than P0. Calf birth weight of all treatments showed no significant difference (P>0.05), but calf weight gain for P3 0.57 kg/calf/day was highest (P <0.05) compared to treatments P0 and P1 so that weaning weight calves P3 to 121.43 kg was significantly higher (P <0.05) than treatments P0 and P1. Estrus post partus for P3 is 2.87 months and calving interval is 12.36 months shorter than other treatments. This shows that the cows whose given concentrate feed mated through artificial insemination / males cattle produces the highest birth weight and calf weaning and short calving intervals.
