ArticleItem Open Access Effect of Early and Split Weaning Performance on Crossbred Gilts (Landracex Desi)(Indian Journal of Veterinary Research, The, 2013) Ravi, P.; Pandey, H.N.; Porteen, K.; Selvaraju, G.; TANUVASEighteen gilts (62.5% Landrace and 37.5% Desi) were randomly divided into two groups (C and T, respectively) having 9 gilts each. Piglets ofcontrol group were allowed to suckle their dams until 56 days of age and kept as control and weaned thereafter. In other half (T), heavier piglets (> 1.2 kg body at birth) were weaned at 28 days and remaining comparatively lighter piglets were weaned at 42 days after birth. Data pertaining to body weight changes, feed intake and different reproductive traits were observed and recorded. Feed cost per sow and weaned piglet were calculated based on local prices of feed ingredients. There was no significant difference between body weights at different weeks post farrowing between two groups. However, both the groups significantly differed (P<0.05) in terms of total body weight loss during suckling period (21.02 and 14.34% loss of body weight in C and T groups, respectively. Weaning-to-oestrus interval was significantly (P<0.05) longer in C. Litter size at birth and average weight of piglet at birth were not affected by treatments. However, litter weight at weaning was significantly lower in T due to early weaning of piglets. There was 18.51 ± 1.46 lost days in C compared to T due to longer weaning to estrus. Litter index was also significantly (P<0.05) higher in T compared to C. Total feed cost per sow and total feed cost on sow per weaned piglets were also significantly (P<0.05) lower, in T compared to C. Thus, it could be concluded from the experiment that early and split weaning system had reduced lactation period in, gilts and also shortened weaning -to-estrus interval, thereby increased the chances of frequency of farrowings per female per year. It also significantly reduced the feed cost per gilts and per weaned piglet.ThesisItem Open Access Prepartum Feeding Management In Relation To Production And Reproduction Performance Of Crossbred Dairy Cows(Indian Veterinary Research Institute;Bareilly, 2003) Bhagirathi Panigrahi; Pandey, H.N.ArticleItem Open Access REPRODUCTIVE PERFORMANCE, MODULATION OF BODY WEIGHT AND FEED INTAKE OF GILTS UNDER SPLIT WEANING MANAGEMENT(Indian Veterinary Association Kerala, 2015-11) Ravi, P.; Pandey, H.N.; Porteen, K.; TANUVASA study on reproductive performance, modulation of body weight and feed intake of sow’sunder split weaning management was carried at Indian Veterinary Research Institute, Izatnagar. Eighteen selected pregnant gilts were randomly divided into two groups of 9 each. In control group the piglets were weaned at 56 days. Intreatment group heavier piglets (> 1.2 kg body at birth) were weaned at 28 days and remaining lighter piglets were weaned at 42 days. Data pertaining to reproductive traits, body weight changes and feed intake were observed and recorded. The result indicate that weaning-to-oes- trus interval was significantly (P<0.05) shorter in treatment group (5.17: 0.21 days) compared to control group (8.68 i 0.42 days). Significant difference has been observed in the body weight loss from farrowing to weaning. The body weight loss in treatment and control group were 20.38: 3.65 and 30.53: 3.18 kg respectively Total feed cost per sow was significantly (P<0.05) lower in treatment group (Rs.1281.42i 112.47) compared to control group (Rs.2022.93i 185.64). There was no signifi- cant difference in the average feed intake of gilts. In conclusion, the split weaning system has reduced the body weight loss, shortened weaning—to-estrus interval and reduce feed cost per gilt. The split weaning system may increase the frequency of farrowings and reduce the maintenance cost of sows
