Intensive System

A total 20 (sixteen female and four male) growing rabbits aged 120 days have been distributed at each farmer’s level in 5 location of Bangladesh; F1 (Dhaka-Pollobi), F2 (Savar-Parbotinagor), F3 (Magura-Boralidhaho), F4 (Magura-Pannandualli), F5 (Magura-Radhanagor) to know the production response and cost effectiveness under intensive in rural condition. The rabbits were reared in their own arrangement. Age of sexual maturity, age of first kidding, percentage of does kidded, gestation period, litter size, weaning period, breeding ratio were not significantly different (P>0.05) among the locations. Feed cost per month was Tk. 903, Tk. 732, Tk. 772, Tk. 1221.96 and Tk. 976 for F1, F2, F3, F4 and F5 respectively for 20 rabbits rearing. Monthly consumption of rabbit meat per family was 4.5kg, 3kg, 2.4 kg, 6.0 kg, in F1, F2, F3, and F5 respectively. Kid mortality (0-10 days) was significantly different (P<0.01) among the locations and this value was recorded 8.47%, 11.11%,12.00%, 8.82% and 13.11% in F1, F2, F3, F4 and F5 respectively. Farmer earned some money by selling their rabbit which was Tk 10200, Tk7600, Tk8400, Tk12400 and Tk7200 /batch and can earn profit around the 49,564; 39,316; 38,536; 62,336 and 35,688 Tk/year in rearing (7batchs/year) 20 rabbit at in F1, F2, F3, F4 and F5, respectively. Rabbit production could be an important micro-livestock component to produce for meeting up extra demand of the country.Bangladesh J. of Livestock Res. 19(1-2): 107-111, Jan-Dec 2012

The study examined the effect of cooling on the reproductive performance of gilts using 27 Large White Experimental Gilts on a Completely Randomized Design (CRD) with 3 systems of cooling, namely Wallow Cooling (WC), Sprinkler Cooling (SC) and Zero Cooling (ZC). Gilts were weighed at the commencement of the experiment and thereafter fed ad libitum from service to farrowing. Feed intake till farrow, feed cost, gilt weight at farrow, date of farrow, litter size and weight were recorded. The feed/piglet weight, feed intake/litter, feed cost/litter and birth weight/piglet were derived. The results showed that feed intake per litter and feed per piglet weight were highest for gilts placed on WC(P< 0.05), followed by SC and least for sow placed on ZC; gilt weight before farrow was highest for sow placed on SC (69.78±0.92), followed by ZC (69.33±0.94) and least for gilts placed on WC (67.33±0.87); litter sizes of gilts placed under the WC and SC systems were similar (5.6±0.41) while that under the ZC system was comparatively smaller (5.4±0.40);while the date of farrow was lowest in the ZC system (113.8±0.32) followed by SC (114.0±0.33) and highest under the WC (114.1±0.33). However, the feed intake per litter, feed per piglet weight, litter sizes of gilts, birth weight per piglet of gilts and the average date of farrow among gilts placed on WC, SC and ZC were not statistically different at 5% level of significance. Though, there is no significant difference in the performance among gilts placed on WC, SC and ZC, temperature regulation through provision of efficient cooling system in piggery would help to increase litter size, improve feed intake per litter and reduce the average cost of feeding gilt per day in maximizing reproductive performances in pigs.Keywords: Cooling, gilts, service, farrow, piggery, litter size, piglet and birth weight

A lesser known vegetable fat, sheabutter fat (SBF) was compared with palm oil (PO) as a dietary ingredient during the rearing phase of pullets. Black Harco grower- pullets (12 weeks old) were assigned to diets in which PO and SBF each quantitatively replaces maize at 2.5 and 5.0% and a fifth diet containing 2.5% each of both PO and SBF. At the 20th week, they were fed a common layer diet until sexual maturity was attained on all treatments. Results at the growing phase did not reveal any significant effects (P>0.05) on feed intake, weight gain, feed/gain and feed cost/weight gain. Sexual maturity was attained by 148, 149, 151, 155 and 158 days for pullets fed 5% Palm Oil, 2.5% SBF, 2.5% PO, 5% SBF and 2.5% SBF/PO diets respectively. PO and SBF at the levels studied were equally tolerated and could replace maize with no adverse effects or growth response. However, a delay in time of lay occurred when both oils were mixed in the diet.

Thirty-six local dose have been used and were divided in to three groups sacording to weight, in each group twelve dose. In the first group the weights of the dose were higher than ( 2.5 kgs) and less than (3 kgs). The second groups was higher than 3 kgs) and less than (3.5 kgs). The third group was higher than (3.5 kgs) and less than (4 kgs). The aim of this study was to obtain the effect of doe weight on her reproductive efficiency (gestation period, litter size, litter weight at birth and weaning, growth rate of offspring preweaning, conception rate and preweaning mortility).  The weight of the doe had no significant effect upon the gestation period and this period was 30.9, 31.2, 31.3 days for the three groups respectively, on the other hand the litter size was affected significantly by doe weight and litter size was at birth and preaweaning (5.1 , 5.8 and 6.2), (4.5, 5.3 and 5.7) for the three groups respectively. The offspring weight at birth and weaning was affected significantly by doe weight and this weight was (40.1 , 48.2 and 53.3 gms), (203.6, 227.5 and 233.8 gms) for the three groups respectively while the conception rate was not affected by doe weight. The mortility percentage in the prewaning period was not significantly by doe weight

At and near Agra, in Uttar Pradesh, India, R. h. hardwickei had a strictly defined annual reproductive cycle. Although many females were inseminated during late February to mid April, ovulation was not recorded until 11 March. Progressively more females ovulated and conceived during the following weeks until the end of April and released one ovum from either of the ovaries with nearly equal frequency. A single conceptus was carried in the ipsilateral uterine cornu during each cycle. The gestation period was 95-100 days. Births occurred between the second week of June and the end of July. Lactation lasted at least 20 days. Females attained sexual maturity at an age of 8.5-9.0 months. Males took at least 16-17 months to attain sexual maturity. Females were segregated during lactation; during the rest of the year, males and females lived together.

ABSTRACTData from 265 female goats (does) from seven herds in Year 1 and 130 does from four herds in Year 2 were analysed using a general linear interactive model for factors affecting gestation period (GP), litter size (LS) and birth weight (BW) of offspring (kids). Gestation period could be described by the regression equation GP = α – 0·890LS –1·072S where S is the proportion of male kids in the litter and the constant (a) depends on breed and herd and was 154·240 (s.e., 0·843) days for British Saanen does in Herd 1. The model established for LS was a quadratic regressional relationship LS = a – 0·000103 (MW - 60))2 + 0-0172 (MW -60) where MW was live weight of the doe at mating and a at MW = 60 kg depends on herd and period of kidding. For early-kidding does in Herd 1 a was 2·277 (s.e., 0·090) kids. The expression BW —α 0·363LS + 0·057P is a simplified multiple regressional form involving BW, LS and parity (P) where a varies according to breed, herd and age of the doe. The estimate of a for kids from British Saanen, 1-year-old does in Herd 1 was 3·879 (s.e., 0·632) kg.

Litter size is an essential trait in rabbit meat production but with low heritability. A selection experiment for ovulation rate has been performed for 10 generations to improve litter size in rabbits. The selected line increased two ova more than the control line but nevertheless a negative correlation was observed with prenatal survival. A transcriptomic study was performed, using microarrays, in ovarian tissue from females belonging to the selected line and the control line. Our results showed 1357 differential expressed genes and nineteen potential biomarkers associated with prenatal mortality, which could explain differences between litter size in rabbits. Cell death was the most relevant process.

The Relationship

At Burgers' Ocean 7 male and 3 female blue spotted stingrays, Dasyatis kuhlii were born over a period of 4.5 years. This paper describes the experiences of the captive breeding results of this species. The first two young died within 2 days of birth. One of them had an internal yolk sac, which may feed the young in the first few days. The other eight animals started to feed after 4 to 9 days on a variety of food types. Birth size of the young increased with increasing age of the parents. Mating occurred directly after parturition, so no seasonality could be defined. Gestation length ranged between 138 and 169 days, with a mean of 144.9±9.0 days (N = 11). Litter size was one, possibly caused by only one active ovarium. Sexual maturity of the two parent animals is approximately 3.5 years. The average feeding rations for the adults ranged between 10.1% BW week−1 (131 kcal kg BW−1 week−1) and 11.3% BW week−1 (172 kcal kg BW−1 week−1), with a feeding frequency of 4 times per week. The relationship between body weight (BW) and wingspan (WS) is given as BW = 3.6 × 10−5* WS2.940 (R2 = 0.9645; N = 45).
