Material type: ; Format:
print
; Literary form:
not fiction
Publisher: 1992Dissertation note: A total of 32 Nili-Ravi cyclic buffaloes were selected for this study. Cyclicity was determined on the basis of presence of corpus luteum and was confirmed by luteal phase levels of progesterone. 10 animals were treated with PGF2-alpha to induce oestrus. The oestrus detection was made by teasing, behavioural symptoins, physical changes and rectal palpation. The receptivity of male was taken as a time for start of oestrus. The ovulation time was determined by repeated palpation and was confirmed by blood progesterone levels. The behavioural signs noted were; acceptance of teaser bull, frequent urination, raised tail, bellowing, restlessness, acceptance of mounting by other females, licking of external genitalia of other animals and loss of appetite. The physical changes recorded were; uterine tone, swollen vulva, mucous discharge on rectal palpation, absence of wrinkles on vulvular lips, hypraemia and wetness in the vagina. There was a little difference in the behavioural symptoms and physical changes among the groups. In the PGF2-alpha treated group the behavioural symptoms and physical changes were slightly more pronounced as compared to natural groups.
The length of oestrus in the natural groups was 23.5 ± 1.5 hours, whereas it was 27.2 ± 2.4 hours in the treatment group. The difference in the length of oestrus among the two groups was statistically significant. The ovulation time in he natural group was 34.6 ± 1.7 hours from the start of oestrus and 11.2 ± 0.5 hours from the end of oestrus. The ovulation time in animals treated with prostaglandin F2-alpha was 39.8 ± 2.9 and 12.6 ± 1 .2 hours in relation to the start and the end of oestrus, respectively. The difference in the ovulation time both in relation to the start and to the end of oestrus between the two groups was significant. The progesterone Values at the time of oestrus were 0. 1 ± 0.02 ng/ml and 0. 1 ± 0. 1 ng/ml in natural and treated groups respectively. And in the luteal phase (13), the progesterone values were 2.1 ± 0.2 and 2.6 ± 1.6 ng/ml in natural and treated groups respectively.

Publisher: 1991Dissertation note: This study was designed to test suitable drugs on the basis of their theraputic effect which are currently in practice to treat endometritis, a problem of high significance among the reproductive disorders of the buffalo in Pakistan.
One hundred and twenty Nili-Ravi buffaloes suffering from 1st degree of endometritis were used in this study. Six groups were constituted, having 20 animals in each group.
Twenty Nili-Ravi buffaloes in group A' were injected 500 mg of cloprostenol (Estrumate) and inseminated at the following oestrous.
Twenty Nili-Ravi buffaloes included in group 'B' were treated with oxytetracycline for five days using intra-uterine route. On next heat the buffaloes were inseminated.
Twenty buffaloes of group 'C' were treated with oxytet-racycline, opted single dose after intrarectally palpating the corpus luteum on the ovary. The buffaloes were inseminated on next heat
Twenty buffaloes of group 'D' were treated with Chioramphenicol for five days using intra-uterine route. The animals were inseminated on next heat
Nili- Ravi buffaloes included in group 'E' were treated with Chloramphenicol after palpating the corpus luteurn. opting single dose. The animals were inseminated on next heat.
The Nili-Ravi buffaloes included in Group 'F' were used as control and inseminated without treatment. During the fertility trials the conception rate calculated after rectal-palpation for pregnancy diagnosis was 60%, 55%, 45%, 50%, 40% and 35% for groups A, B, C, D, E and F respectively.
On the basis of conception rate percentage(60%) and services per conception (1.6) estrumate was declared as drug of choice1,among these tested in the present study.

Publisher: 1992Dissertation note: The comparative study of various egg yolk levels in the extenders used for deep freezing of buffalo semen was conducted at Semen Production Unit, Qadirabad (Sahiwal). The routinely used Lactose-Fructose-Glycerol semen extender was added with 20, 15, 10, 5 and 0% egg yolk concentration in five experimental extenders. 50 ejaculates collected from 10 buffalo bulls were frozen in Liquid Nitrogen. Each semen sample from all bulls and egg yolk levels was evaluated for post-thaw sperm motility, livability and absolute index of livability.
The average values obtained from egg yolk levels and bulls for all test parameters were found statistically high (P < 0.01) at 10 percent egg yolk level as compared to all others. The order of merit for post-thaw motility, livability and the absolute index of livability at 10, 20, 15, 5 and 0% egg yolk level was 45.9%, 43.5%, 42.9%, 33.7% and 8.7% for motility, 9.8, 9.34, 9.3, 7.68 and 2.75 (Hours) for livability and 231.6, 207.95, 204.85, 123.25 and 13.85 for livability index, respectively.
The comparative mean values obtained from each bull were observed non-significant for post-thaw sperm motility but were found significantly higher (P < 0.05) among bulls regarding livability and the absolute index of livability.
On the basis of the results obtained in the present study it may be concluded that due to synergestic effect between glycerol and the presence of 10% concentration of egg yolk in the extender, being comparatively more economical, exhibiting better visibility and on account of high values obtained from motility, livability and absolute index of livability, an extender containing 10% egg yolk level is recommended for the preservation and deep freezing of buffalo bull semen in Liquid Nitrogen for obtaining optimal semen quality.

Publisher: 1993Dissertation note: Data of spermatological traits of 3490 ejaculates obtained during four years (1987 to 1990) from ten Friesian bulls were investigated to see the effects of age, seasons and bulls upon different seminal attributes. The age-wise overall mean values of different attributes of these bulls were: age and body weight at first ejaculation 329.7 days and 337.1 kilograms, number of ejaculates 7.41, ejaculate volume 4.08 ml, mass motility 1.14 grades, initial motility 51.43 per cent, sperm cells concentration 601.09 millions per ml, discarded ejaculates 3.17 and doses produced per ejaculate 32.66 number.
Age exerted highly significant effect (P<0.01) upon number of ejaculates, ejaculate volume, sperm concentration, ejaculate discarded and doses per ejaculate. A significant effect (P<0.05) was observed on percentage motility. There was a non-significant effect on moss motility. The 4th year was proved to be the best age for semen production because mean values of three seminal characteristics namely number of ejaculates, ejaculate volume and percentage motility were maximum during this year. Minimum mean ejaculates were also discarded during the 4th year.
Second year was observed as the worst year for semen production. Minimum mean values of number of ejaculates, ejaculate volume and percentage motility were observed in this year. Maximum mean ejaculates were also discarded during second year of age.
Seasons exerted highly significant effect (P<0.01) upon mass motility, percentage motility, sperm concentration, discarded ejaculates and doses per ejaculate. A significant effect (P<0.05) of seasons was observed upon number of ejaculates but the effect on ejaculate volume was non-significant (P>0 05)
The winter was proved to be the best semen producing season, because two seminal characteristics i.e. mass motility and pci centage motility had maximum mean values in this season Minimum mean ejaculates were also discarded in winter season The second best season was spring, in which ejaculate volume and doses per ejaculate were at their highest mean values
The worst season for semen production was humid hot season. Four seminal attributes i.e. number of ejaculates, mass motility, percentage motility and sperm concentration had minimum mean values in this season. Maximum mean ejaculates were also discarded in humid hot season. The second worst season was autumn. Only mean ejaculate volume and doses per ejaculate were at their lowest margin in autumn.
Highly significant effect (P<0.01) of bulls was observed upon ejaculate volume, mass motility and sperm concentration. Significant effect (P<0.05) of bulls was recorded for initial percentage motility and semen doses per ejaculate. The effect of bulls upon number of ejaculates and ejaculates discarded was found to be non-significant (P>0.05).
Bull No. F 16 proved to be the best bull for semen quantity and quality withmaximum number of ejaculates and maximum ejaculate volume. F 16 was also good in percentage motility, sperm cell concentration and doses per ejaculate. Moreover minimum ejaculates were discarded of F 16 too.
Bull No. 10 was the worst bull. Lowest values were observed in number of ejaculates, percentage motility and sperm concentration. F 10 was also not good in mass motility and maximum ejaculates were discarded from this bull.
The principle conclusion of this study is that if appropriate steps are taken to mitigate the effects of climate and high level of management practices is maintained, there appears to be no reason why high ambient temperatures and humidities should be inimical to successful semen production with Friesian bulls in the subtropical environments

Publisher: 1996Dissertation note: Buffalo plays a pivotal role in the economy of poor and landless farmers. Seasonal calving trend of buffalo has caused shortage of milk during the Summer season when it is required more. This study was undertaken to determine the effect of season on reproductive and productive traits of buffaloes.
In this project Artificial Insemination data of 5 Districts of Central Punjab and breeding data of the Livestock Experimental Station, Rakh Dera Chahi, Lahore were used. Analysis of variance was applied to study the effect of season on Artificial Insemination and Farm data.
Data analysis indicated a significant effect of season on breeding, fertility and calving. Both Artificial Insemination and Farm data indicated high (P<0.05) breeding trend during Autumn and Winter season. Fertility were significantly (P<0.05) low during Autumn. There was no significant effect (P>0.05) of calving season on the calving interval and milk production.
The conclusion revealed that the provision of ideal management, avoiding the extreme weather conditions, ensuring the availability of balanced adequate ration throughout the year and protection from other stresses of diseases etc., it may be possible to derive all the productive and reproductive traits from this versatile animal round the year without any significant effect of the various seasons.
