| Summary, etc. | A study was conducted to find out the adaptability of two crossbred pigs, viz., CB1 (Duroc 50% and Large White Yorkshire 50 %) and CB2 (Desi 50% and Large White Yorkshire 50%) under different housing and feeding systems. Twenty-four weaned piglets from each genetic group were randomly divided into four groups of six animals each and were subjected to four treatments, i.e., group housing with wallowing facility, fed with conventional feed (T1), group housing with wallowing facility, fed with unconventional feed (T2), individual housing without wallowing facility, fed with conventional feed (T3) and individual housing without wallowing facility, fed with unconventional feed (T4). The climatological data, rectal temperature, pulse and respiratory rate at weekly intervals, daily feed intake, fortnightly body weight and behavioural scores of the animals were recorded. The average daily gain (ADG), feed conversion ratio (FCR), total cost of production per kg of live body weight, proximate principles of the feeds and faecal cortisol level were estimated. On attaining the slaughter weight two animals from each group were slaughtered for studying the carcass characteristics. There were no significant differences (P>0.05) in microclimatic variables, viz., maximum and minimum temperature and relative humidity between the treatments. There were no significant differences (P>0.05) in rectal temperature between the treatments but the pulse and respiratory rates were significantly higher (P<0.05) in group housed pigs than the individually housed pigs in both the genetic groups. Significantly higher (P<0.05) growth rate in T3 and T4 groups (individually housed) of CB1 and a trend for higher growth rate in T3 and T4 groups (individually housed) of CB2 were observed. The ADG was highest in T4 followed by T3, T2 and T1 and the FCR on dry matter basis was highest in T2 followed by T4, T1 and T3 in both the genetic groups. Though there were no significant differences (P>0.05) in the behavioural scores, the feeding behavioural score was better was higher in pigs fed with unconventional feed. The quantity of dung voided was highest in pigs fed with conventional feed. The slaughter weight and hot carcass weight (kg) were significantly higher (P<0.05) in the T3 and T4 of CB1 pigs but these traits were numerically higher in T4 followed by T3, T2 and T1 of CB2 pigs. Back fat thickness (mm) was lesser in CB1 than CB2. Individually housed pigs had relatively higher back fat thickness in both the breeds. The loin eye area (cm2) was numerically higher in CB1 than CB2 pigs. The dressing percentage was lower in groups fed with unconventional feed (T2 and T4) and meat yield (percentage) was higher in T3 and T4 in both the breeds. The meat bone ratio was numerically higher in CB2 when compared to CB1 pigs. The moisture level was more in swill (72.03%) followed by chicken waste (71.88%) and infertile egg (59.87)%. The crude protein and ether extract were highest in chicken waste followed in infertile egg and swill. There were no significant differences (P>0.05) in the faecal cortisol level between the treatments of both the breeds. From this study it is concluded that both genetic combination had better performance when they were maintained on unconventional feed irrespective of their housing and feeding systems. Among these two breeds Desi 50% and Large White Yorkshire 50%(CB2) seemed to be economical under unconventional feeding in both the housing systems, considering the cost of production per kg live body weight. |
