Dissertation note Three kiddings in two years or five kiddings in three years refers as accelerated kidding which is helpful to have more kids, helps to fetch higher market prices during off-season. This can also increase life time production in the form of meat, milk and fiber. High reproduction rate is the basiccondition to increase efficiency of production. Most of the goats do not follow seasonal breeding pattern and breed round the year resulting in management problems and high mortality during severe weather conditions. Accelerated kidding strategy is a viable option that affects the health and fertility of the flock. In the present investigation, three experiments were conducted at Small Ruminant Training and Research Centre (SRT&RC) Ravi Campus Pattoki, UVAS, Lahore. The experiment-I was about the initiation of estrus activity in anestrus Beetal goats during low breeding season. Twenty Beetal goats were selected from the existing flock, maintained at SRT&RC. These goats were divided randomly into 4 groups i.e. A, B, C and D having 5 animals in each group. Group A was treated as negative control by offering only green fodder, group B was provided flushing ration along with green fodder (control), group C was kept on green fodder along with hormone therapy of gonadotropin releasing hormone (GnRH) and prostagladin (PGF2?) while group D was provided with green fodder, flushing ration (600 gms/animal) and hormone therapy by providing GnRH and PGF2?. Hundred percent estrus induction was achieved in group B, C and D as compared to group A. The results revealed that fertility rate and kidding rate was high i.e. 80 and 60 percent among animals of B group while animals of control group had less fertility, kidding and gestation rate. The shortest gestation length was found in group B and C while triplet births were observed in goats of group D.
The experiment-II was regarding the initiation of estrus through buck effect in Beetal goats. This experiment was conducted in two phases. Phase 1 comprised two groups A and B for which estrus induction was done during pre-breeding (August) and normal breeding (September/October) season. Similarly, Phase 2 comprised two groups C and D in which estrus induction was done during post-breeding (December) and normal breeding (September/October) season. Different reproductive parameters like estrus, fertility percentage, were noted. The data regarding average birth weight (kg) and gestation length (days) were recorded. Estrus signs were maximum in group B while low in group C. However fertility rate was high in group A, instead of group B. Overall kidding percentage was higher in A group but the lowest in group D. The highest gestation length was observed in group D whereas the lowest value was found in group B. Average litter size was higher in group D as compared to A and B group, respectively.
The experiment-III was conducted to compare productive and reproductive performance of Beetal goats in accelerated and annual kidding systems. Total of 50 adult Beetal goats were divided into two groups viz. accelerated kidding and annual kidding having 25 animals each. The does were selected on the basis of their age, body size, weight and parity. Different breeding bucks were used for each group having similar size, weight and age. All the animals included in this study were fed according to national research council (NRC) nutrient requirements for goats (NRC, 1981). Flushing rations and estrus inducing hormones both were provided to the does of respective groups for preparation of breeding activity during out of season breeding. The annual kidding group was considered as the control group, while the does were bred every eight months for accelerated kidding. The offsprings produced by the pregnant does of 1st batch of both the groups were reared under similar managemental conditions up to maturity. Three crops were produced in accelerated kidding system as compared to two crops in annual kidding system. It was observed that more number of animals i.e. 17 out of 25 showed estrus signs as compared to annual kidding system where 15 animals showed estrus signs. There were non significant differences for number of services per conceptionin two crops under annual kidding groups. Higher percentage of estrus was observed in accelerated to annual kidding. Total number of kids produced in accelerated kidding system was 42 with an average 14 kids in three crops while 23 kids were produced in annual kidding system in two years. Average cost of concentrate was observed high in accelerated kidding system as compared to annual kidding system. Birth weight of kids produced in 3 different seasons i.e. March-April, October- November and June-July were found as 2.84, 2.91 and 2.98 kg. The overall results in term of reproductive efficiency, oestrus behavior and kidding percentage were better in accelerated group than annual kidding.
