ABSTRACT

Alteration during far off dry period feeding management was done to see its effect on body weight and body measurements of Jersey cross bred cows. This study was conducted on 14 healthy dairy animals which were separated into two comparable groups on the basis of almost similar age groups, parity, body weight, and body condition score. Statistically analyzed data revealed that there was significantly higher (p<0.01) tail head thickness in overall dry period and at calving in control group animals than treatment group animals. Significantly higher (p<0.01) overall abdominal girth after 4 months of lactation was found in control group animals as compared to treatment group animals. Significantly higher (p<0.01) body length during overall dry period and at calving was noticed in control group animals. Non significant (p>0.05) difference was reported in body weight and heart girth among control and treatment group animals. The coefficients of correlation indicated high and significant (P<0.01) correlation among body condition score, tail head thickness, body length, heart girth, abdominal girth in this study. It can be concluded that alteration of feeding management practices during far-off dry period does not significantly change body weight during dry period and post partum period but can lead to significant difference in some body measurements of Jersey crossbred cows at tropical lower Gangetic region. Correlation of parameters suggested that the larger body sized animal of same breed may produce more milk.

ABSTRACT

A Transferência de Embrião (TE) contribuiu efetivamente para a produção de equinos e outras espécies. O mercado de muares tem apresentado um contínuo crescimento, entretanto, a aplicação das biotecnologias para a produção desses animais ainda é escassa. O presente estudo avaliou a taxa de recuperação embrionária e as características dos embriões provenientes do cruzamento de éguas com jumentos. Os embriões foram recuperados entre os dias 6 e 9 após a ovulação, dessa forma foi realizada a avaliação da taxa de recuperação embrionária e avaliação das características relacionadas com a idade, morfologia e diâmetro embrionário. A taxa de recuperação embrionária total foi de 55,9% (71/127), e não apresentou diferença para as colheitas realizadas em diferentes dias (D6-D9). Foram recuperados embriões nos estágios de mórula, blastocisto inicial, blastocisto e blastocisto expandido. O tamanho dos embriões variou entre 147-1688μm e a média do diâmetro de todos os embriões recuperados foi de 438,04μm. A recuperação de embriões muares pode ser realizada entre os dias 6 e 9 após a ovulação, e propicia a recuperação de embriões nos primeiros estágios de desenvolvimento.(AU)


Production biotechnologies, particularly embryo transfer (ET) has constantly been contributed to reproduce horses and other species. The mules market has shown continuous growth, however, the biotechnology for mule assisted reproduction is still scarce. The aim of this study was to evaluate the embryo recovery rate and the features of the embryos from mares bred with donkeys. The embryos recovery attempts were performed on days 6 to 9 after ovulation, in order to evaluate the embryo recovery rate and the features related to age, morphology and embryonic diameter in each day. The overall embryo recovery rate was 55,9% (71/127), and there was no significant difference (p>0,05) on different days (D6-D9). Embryos were recovered in stages of mórula, early blastocyst, blastocyst and expanded blastocyst. The diameter of the embryos ranged from 147-1688μm and the mean diameter of all the embryos collected was 438,04μm. The collection of hybrid embryos might be performed between days 6 and 9 after ovulation, and provides recovery of embryos in the early stages of development.(AU)

ABSTRACT

Vinte e quatro bezerros mestiços de Bos indicus X B. taurus, com aproximadamente nove meses de idade, foram distribuídos em três grupos. Grupo I, composto por 18 animais com características fenotípicas consagradas do zebu (presença de cupim, barbeia, pregas prepuciais ou vulvares longas, pele fina e frouxa). O grupo lI foi constituído por seis animais também azebuados, entretanto, com as características acima mencionadas, incompletas e o grupo 111, foi considerado como a reunião (24 animais) dos dois grupos. Sem prejuízo desta classificação, os animais foram alojados em três piquetes. Em cada lote, ficaram oito animais (seis do grupo I e dois do grupo 11). Durante o período experimental, ou seja, de set/88 a ago/89, não foi realizada qualquer infestação artificial dos animais. A cada 14 dias, eram contadas, de todo o hemisfério direito de cada animal, as fêmeas ingurgitadas de Boophilus microplus com tamanho superior a 4,5 mm. O B. microplus esteve presente durante todo o período, contudo, o grau de infestação nos animais foi maior entre maio e setembro. Os bovinos do grupo 11 tiveram uma quantidade significativamente maior de B. microplus do que os animais do grupo I.


Twenty four calves cross-bred (Bos indicus x B. taurus) of both sexes and approximately nine months old were assorted in there groups. Group I comprised eighteen calves with typical zebu phenotype. Group 11 and group 111 were, respectively, consisted of six cross-bred calves without typical zebu phenotypes and ali calves in lhe experiment. Ali calves were kept in· Boophilus microplus infested pastures during lhe experimental period of one year, from Sept/88 to Aug/89. Tick numbers were assessed by counting ali engorged females lenghtierthan 4,5mm. Ticks were present throughout lhe year by infestation burdens was higher from May to September. Tick burdens were higher in group 11 in comparasion to group I.
