“…The does (n=15) received 12.5mg of PGF 2α , was administered (11 days apart) to the does, that does not exhibit behavioral symptoms of oestrus. In this study, estrous periods occurring within 1 to 7 days post-injection were classified as synchronized, although other investigators (Omontese et al, 2014(Omontese et al, , 2016Famakinde et al, 2017;Bello et al, 2019;Parmar et al, 2020) have reported oestrus to begin, after an average interval of ≤50 hrs.…”

In order to provide a more reliable, non-invasive method for defining the reproductive phase and determining the optimum time of ovulation, fifteen (15) apparently normal, non-pregnant cycling Red Sokoto does were used to evaluate exfoliative vaginal cytology sequential pattern; as well as temperature (rectal and vaginal) changes relative to various stages of the oestrus cycle. The does were synchronized by treatment with two luteolytic dosages of PGF 2α analogue (Lutalyse ® , Dinoprost tromethamine), 12.5mg administered intramuscularly in the gluteal region, 11 days apart. Vaginal smears were stained using a modified Papanicolaou method while the vaginal or rectal temperatures ( o C) was recorded with a standard (dry-bulb) clinical thermometer taken from 07:30 to 08:30 hrs daily and monitored throughout the period of experiment. In vaginal cytological smear examination, five exfoliated cell types were identifiable viz; anucleated superficial cells, superficial nucleated cells, intermediate cells, parabasal cells and leucocytes. Typically, the proestrus witnessed an increase in the proportion of anucleated superficial and superficial nucleated cells, with marked reduction in both intermediate and parabasal cells. Oestrous vaginal smear cells were highly cellular and consisted predominantly of superficial nucleated cells. Metestrus and Diestrus phases were markedly similar with respect to cell population and distribution. Metestrus phase showed drastic reduction in number of superficial cells and the proportion of leucocytes in smears began to rise while the desquamation of parabasal and intermediate cells with leucocytosis characterized the diestrus phase. In thermal study, there was significant (P< 0.05) difference in both mean rectal temperature (MRT) and mean vaginal temperature (MVT) values on day of estrus, the same not the case during the three other stages of the oestrous cycle, however, there was no significant (P> 0.05) difference between the mean rectal temperature (MRT) and mean vaginal temperature (MVT). Taken together, these results indicate that vaginal cytologic evaluation and temperature changes can be used as an adjunct tool during oestrus detection and for predicting time of ovulation in this breed; and furthermore, either of diurnal temperature rhythms, MRT or MVT can be used, in combination with other diagnostic tools, as a potential on-farm indicator of oestrous stage in Nigerian indigenous breeds of Red Sokoto does.

“…Adebayo and Chineke [11] in a similar work discovered the presence of extra teat in 5% of goats sampled in the South Western part of Nigeria. The Kalahari red goat is a newly introduced breed of goat into Nigeria few years ago with certain unique features such as ability to adapt easily to the arid and semi-arid savannah, high-quality foraging tendency and excellent mothering aptitude [12] consequently it is popularly known as a "minimum care/maximum profit" breed [13]. The Kalahari red goat has been found to have coat colours similar to the indigenous red sokoto goats but tending more towards the reddish brown colour.…”

Supernumerary Teats in Kalahari Red Goats in the Humid Tropics

2019

Supernumerary teats (SNT) are additional to the usual number of teats found on a cow (four), goat or sheep (two). Information has been provided on the occurrence of teat abnormalities in the indigenous goat breeds in Nigeria but there remains a dearth of information on the incidence of teat abnormalities in the Kalahari red goats (KRG). Fifty two female lactating KRG aged between 2-5 years were classified on the basis of the number of SNT by visual appraisal. Data was analyzed using descriptive statistics and independent sample T-test. 76.1% of the population possesses SNT, 10.9% had one, 43.5% had two, 10.9% had three while 10.9% had four SNT. 60% of the population of KRG with SNT had none of such teats functional/patent. 11.4% had one patent SNT, 25.7% had two patent SNT, 2.9% had four patent SNT. The location of the SNT in relation to the primary teat reveals that 86.3% of the SNT are cranial, 1.3% of the SNT are caudal, 10.0% of the SNT are medial while 2.5% of the SNT are lateral. 74.36% of KRG studied had symmetrical udders while 25.45% had asymmetrical udder. The study concluded that possible reproductive implications of high percentage of SNT in KRG may include neonatal death of kids especially in multiple births and higher risk of mastitis in does. Reproductive Veterinarians and breeders should watch out for goats with SNT when carrying out breeding soundness examination. Contribution/Originality:This study is one of the few studies which have investigated the occurrence of Supernumerary teats in the Kalahari red goats with its reproductive implications. The study also provides one of the earliest reports of Supernumerary teats that are positioned lateral and medial to the primary teat in the goat. INTRODUCTIONSupernumerary teat (SNT) have been described as teats that are additional to the usual number of teats found on a cow (four), goat (two), or sheep (two). Such SNT's can most of the times be non-functional and rudimentary although sometimes they may produce milk [1]. SNT's that have no duct connecting them to the main gland cistern are usually non-functional irrespective of their sizes while SNT's that are functional may be connected to small gland or the main gland cistern thereby possessing the ability to produce milk. The primary teat is a functional teat properly connected to the gland cistern with external orifice. It is usually larger and easily distinguishable from the SNT. Presence of supernumerary teat also known as Hyperthelia, is a common teat abnormality in certain species of livestock which has been reported to have detrimental effects on milking functionality especially with the milking machine. It reduces the machine milking efficiency thereby increasing Animal Review
